Abstract

The construction industry plays an important role in the economy, and the activities of the industry are also vital to the achievement of national socio-economic development goals of providing shelter, infrastructure and employment. It is clear that construction activities affect nearly every aspect of the economy and that the industry is vital to the continued growth of the economy. Surprisingly, the construction industry was left out from the list of major growth drivers of the economy. In order for construction to ably perform this role, there is a need to provide information on its economic value and its place in the overall economy of a country needs to be placed in perspective, if its function is to be fully understood. This study attempted to investigate the relationship between the construction sector and aggregate economy. Time series data from 1990 - 2009 on construction output and Gross Domestic Product (GDP) used for the study were extracted from the United Nation Statistic Division. This paper uses econometric techniques such as unit root test, cointegration test as well as Granger causality test to analyze the significance of construction linkage with the aggregate economy. The result indicates that construction output is Granger caused by GDP, while the construction output also granger causes the GDP. Both GDP and construction output lead each other by one year. The study concluded that the Nigerian construction sector is very important because of its capacity to lead the economy of Nigeria.

... The construction sector remains very important in policy due to its roles in the economy. The contributions and the dynamics of the construction sector vary largely during the development process as an economy transforms from a low income economy into a middle income economy, and eventually into a high income economy (Anaman & Osei-Amponsah, 2007;Oladinrin, Ogunsemi & Aje, 2012;Isa, Jimoh & Achuenu, 2013). ...
... Recent studies now emphasize the impact of the construction sector on the GDP using Nigerian TSD. Oladinrin, Ogunsemi and Aje, (2012) investigate the relationships between the construction sector and the GDP using TSD from 1990 -2009. The study uses econometric techniques and finds bidirectional granger causality between the construction sector and the GDP. ...
... Most of the early studies of construction sector and GDP relationships have been criticised for -limitations of the coverage; the use of CSD across countries rather than country's TSD or panel data; and the focus on the correlation between the construction sector and GDP/GDP per capita (Wong et al. 2008;Lopes, Nunes & Balsa, 2011). More recently the application of econometric methodology has opened a new vista on this subject (Oladinrin, Ogunsemi & Aje, 2012;Abubakar, Abdullahi & Bala, 2018). Anaman (2003) examines the relationship between the construction sector and the GDP using Brunei TSD and finds that the GDP (-1) positively Granger-causes the construction sector. ...

The construction sector makes significant contribution to employment, domestic capital formation and the Gross Domestic Product (GDP). However, the Nigerian Construction Sector (NCS) is beset by a number of challenges including over-dependent on foreign inputs, economic volatility, low linkages and poor project cost and time performance. The study investigates the impact of the construction sector on the GDP using a 47-year annualized Time Series Data (TSD) gotten from the United Nations Statistics Department (UNSD) database. The study employs econometric methodology which involves series of tests and procedures including tests for unit root and cointegration and Polynomial Distributed Lag (PDL) model. The summary of the estimates including the PDL indicate significant effect of the construction sector on the GDP only when the lag of the GDP is not included as one of the regressors. The study concludes that the effect of the construction sector on the GDP is not robust. Finally, the study recommends for a new national housing and transport infrastructure policy for the sustainable development of the Nigerian constructed infrastructure facilities. The study has demonstrated the relationship between the NCS and GDP. The study added to the body of knowledge by using time series data involving the use of distributed lag model (DLM), autoregressive distributed lag (ADL) model and polynomial distributed lag (PDL) model to assess the relationship.
... In other words, the interactions of public policy with the economy have produced the reality of the NCS. Thus, the NCS tends to oscillate with public policies and the economy (Oladinrin et al., 2012). The massive construction investment programme of the 1970s led to construction boom however, the harsh policies of the 1980s including the Structural Adjustment Programmes (SAPs) produced a reverse effect with crushing drop-in construction activities and near shut down of the NCS. ...
... In developing economies, the government has overriding need for improved infrastructure in the total construction output more than developed countries. Since the government institutions are responsible in most countries for the provision of physical infrastructure, the role of the public sector as a client of the CNS in developing economies is generally higher than in developed economies (Opawole and Jagboro, 2017;Oladinrin et al., 2012). Unfortunately, public sector clients are the most liable to default of contract provisions which put construction contractors at serious difficulties. ...
... The Nigerian economy is yet to achieve the much-desired goal of rapid growth and transformation, improved welfare for the citizenry and the reduction in poverty. The real sectors of the economy i.e. agriculture and manufacturing, as well as an important service sector such as the NCS remain in comatose with dwindling contribution to the GDP (Oladinrin et al., 2012). The causes of underdevelopment in the country may therefore be traced mainly to poor economic management, arising from ineptitude of political leadership and economic programmes. ...

Purpose The complex interaction of politics and the economy is a critical factor for the sustainable growth and development of the construction sector (CNS). This study aims to investigate the effects of type of political administration including democracy and military on the performance of CNS using the Nigerian Construction Sector (NCS) as a case study. Design/methodology/approach A 48 year (1970–2017) time series data (TSD) on the NCS and the gross domestic product (GDP) based on 2010 constant USD were extracted from the United Nations Statistical Department database. Analysis of variance (ANOVA) and analysis of covariance (ANCOVA) models were used to analyze the TSD. The ANCOVA model includes the GDP as correlational variable or covariate. Findings The estimates of the ANOVA model indicate that democratic administration is significantly better than military administration in construction performance. However, the ANCOVA model indicates that the GDP is more important than political administration in the performance of the CNS. The study recommends for a new national construction policy, favourable fiscal and monetary policy, local content development policy and construction credit guaranty scheme for the rapid growth and development of the NCS. Originality/value Hitherto, little is known about the influence of political administration on the performance of the CNS. This study provides empirical evidence from a developing economy perspective. It presents the relationships and highlights recommendations for driving growth in the construction industry.
... Building materials industry accounting for more than 50% materials used in the construction industry resulting in the achievement of the national socioeconomic development goals [2]. The sector also regarded as capital goods because its products and services usually constitute other economic activities in another sector [3]. That suggests building materials contributed majorly to the construction industry as materials constitute the largest parts to the construction industry, therefore, providing shelter, infrastructure and employment [2]. ...
... It also suggests that building/construction is one of the major sources of economic growth, development and economic activities bringing all categories of labour force together, such as unskilled, semi-skilled and skilled. That implies building and construction industry is an oil wheel on the Nigerian economy accounting for 60% of capital investment [3]. Without oil, the wheel cannot function effectively. ...
... The building materials industry is an essential component of manufacturing firms and highly visible contributor to the process of growth and prime source of employment generation through production and marketing of products offering job opportunities to unskilled, semiskilled and skilled millions of people globally including Nigeria [3]. However, the sector regarded as corruption haven due to poor quality of materials produce, nonavailability of materials to meet up with demands, overrun budgets, over dependant of foreign materials, and high cost of materials. ...

This study examines the association between the monitoring committee of the board and the financial performance of listed building materials companies in Nigeria for the period 2008-2018. The study population is 15 listed building materials companies in Nigeria, out of which a sample of 11 utilized due to non-accessibility and unavailability of data. The independent variable was board monitoring committees proxies by the executive committee, finance and general-purpose committee, nomination and remuneration committee and statutory audit committee, while return on assets (ROA) used to measured financial performance. Data collected from a secondary source through the annual reports and accounts of building materials companies for the period under review. The ordinary least square (OLS) regression techniques employed for data analysis. The finding reveals a positive and significant association between executive committee, statutory audit committee and financial performance, while shows a negative and significant relationship between nomination and remuneration committee and financial performance. The study recommends that board monitoring committees: the executive committee should increase to the maximum of 5 members, the statutory audit committee should increase from 6 to 8 members, nomination and remuneration should decrease to the maximum of 5 members for all building materials companies operating in Nigeria.
... Babatunde [16] describes government spending on infrastructure as a waste of scare resources that is detrimental to the Nigerian taxpayers because the growth in economy does not reflect the physical really of infrastructural development. As a result, construction industry has not been listed among the major drivers of economic growth in Nigeria [19]. ...
... Empirically, scholars have expressed divergent views on whether public investments in construction sector propel economic growth or vice versa [16,20,26,[44][45][46][47], and especially in Nigeria [3,19,[48][49][50][51][52][53]. However, the perceived need of investments in construction sector is directly dependent on the state of economy and government fiscal and monetary policies [54]. ...
... Oladinrin et al. [19] studied the role of construction sector in economic growth in Nigeria using econometric models and found that there is bidirectional causal relation between construction output and gross domestic product (GDP). This implies that both construction output and GDP drive each other in both forward and backward directions. ...
... Infrastructures development -provision and investment -in Nigeria has been described as good driver of economic growth, especially that most of purported obtained public foreign and domestic loan facilities were meant for infrastructural development (Ojo, 2010) and economically huge (Oladinrin et al., 2012) in terms of fixed capital formation. Also, a number of reports (Stewart, 2010;Oladinrin et al., 2012;Olaoye, 2016;Fasoranti, 2016) confirmed the performance trajectory of the construction sector's GDP share contribution of 3.8% (in year 1960), 4.22% (in year 1965), 4.38% (in year 1970), 5.70% (in year 1975) and massive 10% (in year 1979) before its declined to an average of 4% in the late 1980s and 1990s. ...

Anyanwu (2012) opined that the decline may be due to shocks in government revenue, political instability of the military eras, public corruption, public economic policies summersault and deficits in public infrastructure spending. ...
... Agbonkhese and A.E. Ojo Asekome (2014) are of the opinion that public expenditure explains the seeming market economic failure, inefficient and inequitable allocation of economic resources for social and economic infrastructure development. Oladinrin et al. (2012) earlier study of the significant causality linkage and relationship between the Nigerian construction sector output and aggregate economy between years 1990-2009, concluded that construction output is Granger caused by GDP and vice versa. Ajayi and Kolapo (2018) examined the sensitivity of domestic private investment to macroeconomic indicators in Nigeria from 1986 to 2015. ...
... The relationship between the Economic Growth and Environment Sustainability (EGNES) 1(2) (2022) 58-63 construction industry and the economy is such that an increase in construction activities will most likely result to an increase in GDP of a country through the multiplier effect. The multiplier also gives rise to an increased demand for construction requisitions (Oladinrin, Ogunsemi and Aje , 2012). The level of the GDP is a major determinant of the demand of the demand for construction work in any economy. ...
... Provided there is stability and high value in the price of crude oil (which is the main stay of the Nigerian economy) in the international market, the construction in Nigeria is estimated to continue on a growth trajectory if the development of capital project that will boost socio-economic activities remains a priority of the government (Oladinrin et al., 2012;Dantata, 2008). ...

All over the world, there is a general consensus that the construction industry is an important driver of economic growth and prosperity in developing countries such as Nigeria. The nature of activities in the industry is such that human and material resources are mobilized and effectively deployed in both the construction, rehabilitation and maintenance of housing and infrastructure projects for the purpose of reducing unemployment locally and enhancing the general economic wellbeing of a nation through the provision of the requisite infrastructural and commercial structure which are indispensable requirements for the advancement of all other sectors of any economy. However, due to its uniqueness and coupled with the huge financial resources required to actualize a construction product, its procurement has been known to be susceptible to wastage, fraud and other forms of corrupt practices. It was these susceptibilities that led to the introduction of the Nigerian Public Procurement Act in 2007. Consequently, this paper looks at the likely effect of an effective procurement procedure for construction projects on national development. Data for this paper were sourced from mainly from secondary data sources which include journal articles, textbooks, the internet and other types of literature. The paper concluded that a anybody found to have contravened the provisions of the Public Procurement Act no matter how highly placed should be prosecuted publicly and appropriate sanctions meted out to deter any other would be offender also, a sound public procurement system for public projects in the construction industry and a motivated workforce will significantly impact productivity and national development, enhance effectiveness in government spending, ensure infrastructural development and improve the welfare of the people while also reducing corruption, wastages and sharp practices to the barest minimum.
... Many large-scale construction projects have failed due to cultural differences among companies [42]. Given the importance of the construction industry, it is essential to pinpoint the key problems hindering its effectiveness and implement solutions to boost Pakistan's economic growth and development [43]. To improve the construction sector's effectiveness and advance Pakistan's economic development, it is essential to identify the key problems and take remedial action [44]. ...

The construction industry is considered a driver of economic growth, especially in developing countries. However, the successful completion of construction projects is a major challenge, due to the lack of competencies. The current study explores the effects of communication management practices, clarity in the scope of the construction project, and organizational culture to enhance project success. A project manager is essential in running a project smoothly and according to the schedule. Keeping in view the predominant role of the project manager, this study aims to find the moderating impact of manager competencies to improve the construction project routine and generate successful projects. A questionnaire survey was conducted to collect the data and determine how these variables influence construction project progress. The current research results show an excellent association between a construction project’s success and the discussed independent variables. Additionally, it was found that a competent project manager can play a better role in preventing the uncomfortable influences of independent variables on the dependent variable. The obtained outcomes highlight the importance of adequately handling organizational culture, communication management, and clarity to achieve project success. These outcomes are helpful for the professionals working in the construction sector to raise the project success rate and enhance their construction management capabilities.
... Safety issues in the construction industry The global construction industry has remarkably evolved over the years, with significant stake in economic development through infrastructure projects (Okeola, 2009;Oladinrin et al., 2012). Despite this stride, issues regarding operational safety still plagues the industry. ...
... Safety dynamics in the Nigerian construction industry Despite the socio-economic benefits derived from the construction industry in Nigeria (Isa et al., 2013;Oladinrin et al., 2012), the safety dynamics in the industry has been deplorable (Agbede et al., 2016). The construction industry employing the largest labour force in developing countries such as Nigeria has been noted to account for a relatively high number of all occupational injuries and fatalities resulting from accidents on work sites (Arumugam & Thirumurthy, 2007). ...

Designing for construction safety entails safety considerations of construction workers and end-users in the design of a project with a view to improving safety performance in construction project delivery. Despite the apparent potential benefits of Design for Safety (DfS) in curbing the persistent safety hazards and accidents faced in the conduct of construction activities, little or no effort has been made in most developing countries including Nigeria to ensure its wide adoption and implementation. This has been argued to be largely due to the dogmatic attitude of such developing industries towards conventional safety support systems and mechanisms. Thus, with a view to put the argument into clearer perspective, and also set the scene for effective DfS implementation in Nigeria, this study aimed to assess the level of awareness and readiness of professionals towards accepting the concept of DfS, and the possible changes that need to be made in the industry to facilitate its implementation. A quantitative research approach was adopted using a structured questionnaire to elicit data from randomly sampled professionals often involved in design for construction projects in the Nigerian construction industry. Data collected was analyzed using descriptive statistical methods. The findings of the study showed a relatively low level of awareness of the concept of DfS amongst industry professionals, and the need to constitute safety training programs that will go a long way in changing the perception of the design professionals towards safety. This will provide them with deeper insight on the contemporary trends in safety management tools and techniques for improved safety performance.
... The construction industry globally is a fundamental economic sector that permeates most of the other sectors as it transforms various resources into physical, economic and social infrastructure necessary for socio-economic development (Oladinrin et al., 2012). In Nigeria, the construction industry occupies an important position in the economy and has great potentials of becoming one of the biggest construction markets, yet it contributes less than other industries (Olowa, 2018). ...
... The activities of the industry are also proportional to the achievement of socioeconomic developmental goals. This view was corroborated by Oladinrin, Ogunsemi, and Aje (2012), that the construction industry, by its nature, has many special problems and requirements that contribute to developmental growth. Some of the problems are a result of the way the industry run and carry out its activities. ...
... The 10 most important effect of delay from the overall view of respondents As shown in Figure 2, the top 10 effects of delay in Algerian construction project were: 1) Time overrun: all the three parts agreed to classify 'time overrun' as the first most important effect with an importance index of 4.14; when projects are delayed, more days of work is required to finish the execution of the project, as a result, the prescribed delivery time is extended and the project is said to have experienced time overrun [19,41]. This result was supported by various researches [1,3,15,24,28,30,31,33,35,37,39,41,45] in which 'time overrun' was the first most important effect of delay. ...
... 5) Failure of the project: received 5 th from the overall ranking with RII of 3.76; a successful project is one that has reached its triple constraints of time, cost, and quality [15,28]. Delay in construction project causes time overrun [1,3,15,17,19,27,33,35,39,41,45], cost overrun [1,3,6,15,16,24,25,27,39,41,42,45], poor quality [15,17,34,41,42,45], non-achievement of objectives and thus failure of the project. This result was supported by [16] 6) Negative impact on the economy of the country: is the 6 th effect with an index of 3.76. ...

This paper examines the effects of delays in the Algerian construction industry in order to identify the various critical aspects of the causes for improving the economy in the construction sector. A questionnaire survey was conducted to assess the perceptions of all players in the construction industry, which led to the identification of the most significant impacts of delays. The results show that ten main effects of delays in the construction sector are at the origin of many constraints that have a negative impact on the economy of the country. Further, the factor analysis technique was performed to categorize the identified effects into main groups, and it yielded 5 groups (factors). As an important contribution, the relationship between these groups was tested using the SMART-PLS, and a structural model has been developed. Also, a comparative study with other previous works on the most critical effect of delays in construction projects has been conducted and the results show that the main effects of delays in the construction industry are at the root of many constraints in reaching and achieving the objectives.
... Construction activities are generally referred to as a leading economic sector since it forecasts an economy's overall path. Also, it contributes significantly to attaining national socialeconomic development goals by providing shelter, infrastructure, and job opportunities [16,37].

This study identifies that the underlying root cause of construction disputes is contract incompleteness caused by bounded rationality and uncertainty. Using the relative importance index (RII) and confirmatory factor analysis(CFA) from SEM AMOS, this study examines the occurrence likelihood and significant effect on dispute occurrence in the contract incompleteness minefield (ambiguity of contract document (AOD), deficiency of contract document (DOD), inconsistency of contract document (IOD), and defectiveness of contract document (CDD)), and the manifestation of opportunism (violation of commitment(VOC), forced renegotiation (FRC), evasion of obligations (EOB), and refusal to adapt to change (RAC)). A large-scale survey of 350 professionals from the Nigerian construction industry was conducted. The RII result of the highly ranked minefield of the manifestation of contract incompleteness shows the interrelationship between contract incompleteness and dispute occurrence. Likewise, the CFA result significantly affects contract incompleteness on dispute occurrence. Therefore, the need to minimise contract incompleteness in the Nigerian construction industry becomes a pertinent issue to reduce dispute occurrence.
... The construction industry is very crucial to the development of any country [1,2]. The interdependency of the sector to the economic growth of any nation can be measured by development in physical infrastructures, such as buildings, roads and bridges [3][4][5][6]. Isa, Jimoh, and Achuenu [7] opined that the sector contribute significantly to the country's Gross Domestic Product (GDP) and he industry is full of inherent potentials, such as self-sufficiency in cement production that will stabilize the materials sector and the huge deficit in physical infrastructure which is key to creating opportunities for sustainable development. ...

The research focuses on the construction site management practices and the challenges that impede such practices in Ondo and Lagos states of Nigeria respectively with the view of minimizing waste and improve sustainability concept on public project delivery. The research survey targeted Architects, Quantity Surveyors, Builders and Civil Engineers affiliated with indigenous contracting firms through the administration of well-structured questionnaires. A simple random sampling technique was adopted in choosing the research respondents. The collected data were analyzed using both descriptive and inferential statistics. Out of 301 questionnaires distributed, only 135 questionnaires were returned and analyzed with 44.85% response rate. In-depth interview were also conducted on some selected site workers (labors) to elicit their views on the level of awareness and adoption of site management practices in their various sites. The results shows that minutes writing, resource leveling, cash flow management, proper payroll and daily work report are the five (5) topmost site management practices adopted on construction sites in the study area. The study also shows that respondents are highly aware about the site management practices. The result further shows that Lack of standardization in equipment management, plant hiring/purchasing problems, lack of on-site assistance, wrong curing procedures, ineffective communication practices, are the five major challenges that impede site management practices in the study area. Analysis of the transcribed interview shows that the site workers (labour) aware about the site management practices but are rarely followed judiciously. The research seeks the opinion view of construction professionals in the study area which may not be generalize to all other construction sites in southwestern geopolitical zone of Nigeria; construction site workers needs to be kept abreast of the site management practices by organizing regular training for all cadre of site workers. The implication for practice is that investing in training will improve productivity, loyalty, minimizing of waste to the environment and increase contractors profitability. The study seeks to support the concept of buttressing the awareness on practicing adequate site management strategies on construction sites rather than relying on theoretical concept on the subject matter. It supports the proposition that adequate awareness of these practices will improve construction project performance.

The construction workers are facing several problems due to COVID-19 in the construction industry like anxiety, depression, fatigue, and mental disorders, it also causes workplace injuries, disabilities and reduces productivity, and has a negative impact over the performance of the project. So, it is important to find out the remedial measures of the COVID-19 pandemic on workers’ health and productivity, as COVID-19 has affected the construction industry globally. From the questionnaires factors of COVID-19 and productivity had been ranked according to their mean value, then the unstructured interviews have been conducted from the field experts and obtained possible remedial measures from the interviews found to be safety precautions, friendly environment, security measures and others. If the construction industry faces a reduction in productivity, thenfor increasing productivity employees must know about their job status, set achievable deadlines for work, and take decisions wisely.
... Hence, it is essential to examine both the micro and macro parameters involved to make continuous progress in the construction sector [5,6]. The sector is the demonstration of business growth, providing opportunities via socio-economic activities [7][8][9]. The growth of this sector is based on the adaptability of new technologies [10][11][12]. ...

Digitalization in the construction sector is a need of the modern world. Not only the infrastructure, but also the quality of life, is improved by the digital transformation in the construction sector. Digital technologies are being widely used in construction. The impacts of implementing digital technology on transformation in the construction industry, however, have not yet been thoroughly understood. Considering this aspect of the construction industry, this study reviews the articles in the field of digitalization of various segments in the construction industry. In this manner, the Scopus database was considered to gather the relevant articles based on the keywords (((“Digitalization” OR “Digitalisation”) OR “Reforms”) AND “Construction” AND “Energy”). These keyword combinations provided a list of 126 articles and, following the protocol of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), the number was reduced to 35. The review showed that the major targeted areas in the construction sector based on digital transformation are smart construction, optimization of energy, sustainable environment, wireless technology, and economic and architectural growth in which the role of Building Information Modelling (BIM) and prefabricated construction is noteworthy. The involvement of digitalization in numerous fields has improved quality of life. It increases production and has the potential to automate the industry more effectively. This study shows how the adoption of digital technology has improved comprehension and laid the foundation for a digital transformation in the construction industry.
... Construction products serve as hosts to economic activities, while the construction process provides direct and indirect employments to citizens thereby enhancing the overall economy of a nation. Globally, the construction industry remains critical to the attainment of the socio-economic objectives of nations, and this is amplified in the case of the Global South [1]. Taken together, construction and related industries account for more than 10% of Nigeria's GDP [2]. ...

Considerable efforts have been made in literature to mitigate the occurrence of errors in construction projects without much results. Previous studies on construction errors overly focused on design errors, neglecting errors which may originate from other construction procurement documents. Errors in procurement documents often undermine the attainment of construction project objectives in terms of completion within agreed time, quality and cost. Yet, this phenomenon finds inadequate explanation in the literature. This study was undertaken to evaluate errors in construction procurement documents, ascertain the difference in the impacts of documentation errors in different procurement methods, and determine the influence of documentation errors on the cost performance of construction projects. The respondents, architects, engineers, builders and quantity surveyors (n=81), were selected using convenient and snowballing techniques, and the data were analyzed using severity index (SI), mean score (SC) and Kruskal Wallis test. Based on the respondents' opinions, errors in project contextual factors have the highest rank in terms of impact on the cost performance of projects followed by errors in project time schedule and design errors. The Kruskal Wallis test confirmed that these three highest ranking errors have significant effects on the eventual cost performance of projects. Clients and project managers should ensure that contextual factors are fully understood by project participants in order to obtain procurement documents that are devoid of errors. This study opines that construction procurement documentation errors should be assessed by their impacts on cost project performance, and not merely by their occurrence.

Efficient project delivery in the context of contemporary construction management is dependent on large volumes of data. However, due to pertinent challenges underlying implementation, easy access to key construction management data remains a significant hurdle. Management is quickly transforming to facilitate the employment of predictive decision-making methods, wherein the digitalization of construction data functions as a crucial component. The Architectural, Engineering, and Construction (AEC) industry has been trailing behind in the implementation of modern management concepts as well as novel technologies. However, it is vital to re-engineer construction management to be on par with other related industries, such as manufacturing, oil, and gas. The advent of Building Information Modeling (BIM) has been attributed to the paradigm shift that construction management is currently undergoing. BIM is a platform equipped with unique and effective tools to support the implementation of management techniques. This research critically reviews challenges plaguing conventional construction management and decision-making solutions for construction management as devised by BIM. This review focuses on construction management’s four key bottom lines (i.e., schedule, cost, quality, and safety management) and how a BIM-based construction management platform helps monitor these aspects. This review revealed that the primary focus of the researchers was to develop BIM-based automated prediction models and enhance communication and collaboration among project participants. Based on the findings of this research, a BIM-based construction decision-making framework was proposed. This roadmap provides construction organizations with the information required to implement a BIM-based decision support system for project management. Finally, the research identified several knowledge gaps and the potential for future research.

The construction sector in India is in the government's intense focus on creating a world-class infrastructure balancing environmental conservation. Adopting green procurement practices by mitigating adoption barriers is necessary for Indian construction firms to achieve the goal. However, none of the existing research identified the comprehensive list of barriers, analysed their impacts on green procurement adoption, prioritized the barriers and formulated the solution strategies to mitigate them and maximize green procurement adoption for the Indian construction sector. To bridge this gap, this study has identified barriers, analysed their impact, prioritized the criticality, and developed the solution strategies to alleviate them. Questionnaire surveys and descriptive statistics are first performed for data analysis of the firms based on the firm's size and domain of expertise. Later, an analysis of variance (ANOVA) is performed and identified the significant differences in the impact of the barriers on Indian construction firms having different sizes or domains of expertise. The fuzzy best-worst method (FBWM) is then used to identify the most significant barriers as “reduced commitment from higher management”, “lack of management support”, and “perception of higher cost for adhering to green procurement”. Finally, the Delphi technique and assessment of various portals of the Government of India (GOI) have been carried out to identify the solutions to mitigate the barriers. The research results in an original and unique approach to identifying and analysing the critical barriers to green procurement adoption and their impact on different categories of Indian construction firms. It has identified the topmost barriers and then the solution strategies Indian construction firms and GOI need to focus on to embrace green procurement. The procurement managers can identify the top-rated barriers derived from the present study to closely focus and make strategies to eliminate them, helping their organisations adopt green procurement practices. The solution strategies derived from the study may be ready to implement action plans for construction and infrastructure companies of India, environmental and social development of the country, and assisting the GOI in developing and implementing the policy of green procurement for the Indian construction industry.

The construction sector plays a significant role in contributing to uplifts in economic stability by generating employment and providing standardized social development. Economic sustainability in the construction sector has been less addressed despite its wide applicability in the economy. This study aimed to perform a comparative analysis to determine the application of a circular economy in the construction sector toward economic sustainability, along with its long-term forecasting. A time series analysis was used on the construction sector of the United States of America (USA), China, and the United Kingdom (UK) from 1970 to 2020, by taking into account individual effects to propose a framework with global validity. Statistical analysis was performed to analyze the dependence of the construction sector and determine its short- and long-term contributions. The results revealed that the construction sectors in these countries tend to bounce back to equilibrium in the case of short-term effects; however, the construction sector behaves differently with respect to each sector after experiencing long-term effects. The results show that the explanatory power of the forecasting model (R2) was found to be 0.997, 0.992, and 0.996 for the USA, China, and the UK. Based on the concept of the circular economy, it was concluded that the USA will become a leader in attaining sustainability in construction owing to its ability to recover quickly from shocks, and that the USA will become the largest construction sector in terms of GDP, with a USD 0.3 trillion higher GDP than that of the Chinese sector. Meanwhile, there will be no significant change in the construction GDP of the UK up to the end of 2050. Moreover, the speeds of the construction sector toward equilibrium in the long run in the USA, China, and the UK, and regaining of their original positions, is 0.267%, 1.04%, and 0.41% of their original positions, respectively. This study has a significance in acting as a guideline for introducing economic and environmental sustainability in construction policies, because of the potential of the construction sectors to recover from possible recessions in their respective countries.
... The Egyptian government is making significant efforts to execute many construction megaprojects to meet Egypt's Strategic Growth Strategy 2030 goals. Economically, the construction industry significantly increases countries' gross domestic products (GDP), provides new employment opportunities, provides fixed capital assets and infrastructure to most countries, and allows other industrial sectors to flourish [1]. Construction projects are rarely completed on schedule or within budget, and reworking is frequently required to meet customers' needs [2]. ...

Despite the use of numerous new and advanced technologies in construction projects, the industry’s efficiency remains low. This business has faced significant challenges for a long time, such as non-value-added activities, also known as waste. Lean construction (L.C.) is one method for improving the situation by reducing waste and increasing value for the client. This study provides an in-depth literature review to provide a comprehensive list of all critical drivers and groups all these drivers into one research paper in order to determine the importance (weights) of these drivers and their relative importance, and to propose an innovative methodology for ranking them using Simos’ approach. Seven construction project case studies were proposed. Their lean status was assessed, the key-list was verified using a Weighted-Sum Model as a multi-criteria decision-making technique to rank them, the best one in terms of lean implementation was found. Subsequently, a sensitivity analysis was conducted to determine the most critical criterion for the key list. The following are some of the study’s main findings: 18 key drivers were identified and ranked, a clear definition of the client’s requirements was the most global weight between factors, and the case studies demonstrated that more than 60% of the lean drivers are implemented in Egypt. Day-to-day observation and standardized work were the top two most widely used lean practices in Egypt.

This study presents evidence of a developed ensemble of ensembles predictive model for delay prediction-a global phenomenon that has continued to strangle the construction sector despite considerable mitigation efforts. At first, a review of the existing body of knowledge on influencing factors of construction project delay was used to survey experts to approach its quantitative data collection. Secondly, data cleaning, feature selection, and engineering, hyperparameter optimization, and algorithm evaluation were carried out using the quantitative data to train ensemble machine learning algorithms (EMLA)-bagging, boosting, and naïve bayes, which in turn was used to develop hyperparameter optimized predictive models: Decision Tree, Random Forest, Bagging, Extremely Randomized Trees, Adaptive Boosting (CART), Gradient Boosting Machine, Extreme Gradient Boosting, Bernoulli Naive Bayes, Multinomial Naive Bayes, and Gaussian Naive Bayes. Finally, a multilayer high performant ensemble of ensembles (stacking) predictive model was developed to maximize the overall performance of the EMLA combined. Results from the evaluation metrics: accuracy score, confusion matrix, precision, recall, f1 score, and Compute Area Under the Receiver Operating Characteristic Curve (ROC AUC) indeed proved that ensemble algorithms are capable of improving the predictive force relative to the use of a single algorithm in predicting construction projects delay.

The disruption by COVID-19 from its entry into Lagos in February, 2020, has affected various sectors of the economy and particularly, the fisheries sector. While it has been reported that COVID-19 virus does not infect seafoods, it has been found to alter food systems. This study assessed the pains and gains (impacts) of COVID-19 pandemic on the fisheries at the fishing settlement, retail, wholesale and industrial levels using questionnaires, interview sessions with key management and relevant personnel, focused group discussions as well as secondary data from the target industry. It covered period before lockdown (pre-COVID-19; December 2019-February, 2020), during lockdown (COVID-19 lockdown; March-June, 2020) and that following the lockdown (post-COVID-19; July-August, 2020). Qualitative and quantitative data from artisanal, retail, wholesale and industrial sub-sectors showed that while the pandemic caused decline in income and impairment of livelihood, it increased costs of logistics, electricity supply, production and commuting while the quality of seafood harvested was unaffected. It had positive impacts on personnel health consciousness and hygiene, fish catch at both the artisanal and industrial sub-sectors, and reduced stress levels but varying effects on fish consumption, staff emolument and cost of products.

Purpose – The paper aims to establish the most underlying factors causing construction projects delay from the most applicable. Design/methodology/approach – The paper conducted survey of experts using systematic review of vast body of literature which revealed 23 common factors affecting construction delay. Consequently, we carried out reliability analysis, ranking using the significance index measurement of delay parameters (SIDP), correlation analysis and factor analysis. From the result of factor analysis, we grouped a specific underlying factor into three of the six applicable factors that correlated strongly with construction project delay. Findings – The paper finds all factors from the reliability test to be consistent. It suggests project quality control, project schedule/program of work, contractors’ financial difficulties, political influence, site conditions and price fluctuation to be the six most applicable factors for construction project delay, which are in the top 25 percent according to the SIDP score and at the same time are strongly associated with construction project delay. Research limitations/implications – This paper is recommending that prospective research should use a qualitative and inductive approach to investigate whether any new underlying factors that impact construction projects delay can be discovered since it followed an inductive research approach. Practical implications – The paper includes implications for the policymakers in the construction industry in Nigeria to focus on measuring the key suppliers’ delivery performance as late delivery of materials by supplier can result in rescheduling of work activities and extra time or waiting time for construction workers as well as for the management team at site. Also, construction stakeholders in Nigeria are encouraged to leverage the amount of data produced from backlog of project schedules, as-built drawings and models, Computer-Aided Designs (CAD), costs, invoices, and employee details, among many others through the aid of state-of-the-art data driven technologies such as artificial intelligence or machine learning to make key business decisions that will help drive further profitability. Furthermore, this study suggests that these stakeholders use climatological data that can be obtained from weather observations to minimize impact of bad weather during construction. Originality/value – This paper establishes the three underlying factors (late delivery of materials by supplier, poor decision making and Inclement or bad weather) causing construction projects delay in Nigeria from the most applicable.

Life management controls the quality of one’s work while ensuring one’s quality of life with minimum conflicts. The contractor’s site quantity surveyor (QS), who has to shoulder many responsibilities on-site amongst time constraints, can most probably experience a life imbalance. Because the personal responsibilities of female and male site QSs differ, the aim of this study was to identify the strategies that will enhance the life management of contractor’s site quantity surveyors. The qualitative approach was adopted in the study, and the required empirical data were collected by interviewing 20 females and 20 males contractor’s site QSs. The interview findings were analysed using manual content analysis. Thirty-one and twenty-eight causes of life imbalance in male and female QSs respectively were identified. In addition, 50 and 48 strategies that will facilitate satisfactory life management in male and female QSs, respectively were identified. Some of the identified causes and strategies were common to both male and females QSs.

Chapter
The contribution of the construction industry to the economy of any nation has been proven to be very important not just because it provides the infrastructural need which serves as an indicator of its development but also its immense contribution to the Gross Domestic Product (GDP) . This has placed the industry in a vantage position in calls for adequate financing. In developing countries such as Nigeria, the government is largely responsible for financing capital projects. Over time, it has been experienced that the low gross domestic savings of the nation has inhibited the adequate financing of capital projects, hence leading to a deficit in the provision of infrastructure. Foreign investment which could be either Foreign Direct Investment (FDI) or Foreign Portfolio Investment (FPI) serves as an alternative for capital investment financing and comes with its own benefits to the host nation. This study theoretically examines the infrastructural development in Nigeria and foreign investment in Nigeria with particular emphasis on the construction industry. Findings revealed that the inflow of foreign investment into the construction industry has been irregular and being inhibited by varying factors. The study concludes by emphasizing the need for collaborative efforts by government and other stakeholders to ensure the increase and stabilized inflow of foreign investment into the construction industry by creating a convenient investment environment and strengthening existing enabling investment laws.

The impact of different hazardous substances of the construction industry being released to the environment is alarming. This constitutes an adverse effect on the quality of life of construction workers and the populace at large. To reduce this menace, Environmental Management System (EMS) was put in place. Meanwhile, the implementation of EMS in the Nigerian construction industry (NCI) is not certain. This study, therefore, investigated the barriers to EMS implementation in the NCI to group them into a smaller form, i.e., fewer numbers. A questionnaire survey was developed and administered to construction professionals in Nigeria using a purposive sampling technique. The retrieved 106 copies of the questionnaires were subjected to both descriptive and inferential statistics such as mean score, standard deviation, analysis of variance test, post hoc test and exploratory factor analysis. An exploratory factor analysis was conducted three times to identify the critical barriers to EMS implementation in the NCI. The study findings reveal three main categories of barriers affecting EMS implementation, namely; (1) knowledge barrier; (2) process barrier; and (3) culture and management barrier. The study concluded that the three factors indicate the major cardinal barriers that could describe the impediment of EMS in the NCI. It was recommended that the training of construction professionals is important to enhance improvement culture in the NCI.

Public policy on construction will reflect the economic, political, social, and cultural status of Sri Lanka. The construction industry in Sri Lanka has faced many issues in the recent past because of unsuccessful government policies. Therefore, an effective national policy for the construction industry has become necessary. Thus, the aim of this study was to examine the effectiveness of the existing construction policies. The empirical data required were collected by interviewing ten experts, who were selected using snowball sampling. The collected data were manually analysed using content analysis. The findings revealed that the National Policy on Construction (NPC), formulated by the National Advisory Council on Construction, which was set up under the Construction Industry Development Act No. 33 of 2014, is the only construction policy that has been formulated in Sri Lanka so far. NPC contains eighteen (18) policies applied for both the public and private sectors. Although according to the literature, policies in Sri Lanka change along with the change of governments, the study revealed that NPC, which has remained unchanged since its formulation in 2014, is still applicable in the country.

The increasing rate of poverty and unemployment in Nigeria has necessitated further efforts towards alternative means of reducing the trend, outside the government's microeconomic mechanisms. As a sector with multiplier effects on other sectors of economy through its numerous activities, the construction sector is expected to reduce both poverty and unemployment. This study, therefore, examined the relationships between construction sector variables, poverty and unemployment rates in Nigeria. Using socioeconomic data published by the Central Bank of Nigeria, National Bureau of Statistics, United Nations Development Program and World Bank from 1981-2019, the study deployed an Autoregressive Distributed Lag (ARDL) approach to analyze the relationships between construction sector variables, poverty, and unemployment rates. It also used Granger causality test to determine the direction of causation between the variables under investigation. The results showed that there are both long-run and short-run dynamic relationships between poverty rate and construction sector variables (F-stat. (3.93) > upper (3.67) and lower (2.79)) bounds. It showed that no long-run balanced relationship exists between the unemployment rate and construction sector variables (F-stat. (2.01) < lower (2.79) and upper (3.67)) bounds. The result further revealed that there are significant and positive linear correlations between construction sector variables, poverty, and unemployment rates; except between construction output and poverty rate, where an insignificant linear relation was established. Nevertheless, the relationships could not result to direct causal effect, except a unidirectional Granger causal relationship that flows from government capital expenditure to construction service recurrent expenditure and construction output, and from construction service recurrent expenditure to construction output. Consequently, the study suggested that construction sector expenditure and output should be directed towards poverty and unemployment reduction. This could be done through the diversification and integration of all construction sub-sectors, particularly the private sector into the nation's economic equation. Thus, this study would direct the paths of policy makers and construction planners towards the right construction policies and plans that would lead to reduction in unemployment and poverty rates with a long-term economic transformation in Nigeria.

... The construction industry is one of the sectors that creates the most employment opportunities for unskilled and semi-skilled workers from impoverished local communities due to its relatively labourintensive nature (Phoya, 2012). It is the driving force behind the economic growth due to its operations having an impact on most sectors of the economy (Oladinrin, Ogunsemi and Aje, 2012). In addition, it contributes indirectly to employment creation in other sectors as most materials used are sourced from these sectors of the economy (Ngandu, Garcia and Arndt, 2010).Notwithstanding its important role and contribution to economic growth, the construction industry remains a risky sector where the most vulnerable (unskilled and semi-skilled) workers are continually involved in serious construction accidents. ...

The purpose of this study was to develop a client-driven H&S rating model to be used by construction clients to improve their overall project H&S performance. The attitude of clients towards H&S is critical in the overall H&S improvement effort on construction projects. This hypothesis was tested and verified using Covariance-Based Structural Equation Modelling (CB-SEM). Using the framework of factors from previous studies, a survey method was adopted for collecting data for this study. Contrary to the findings of the previous studies, the final CB-SEM results suggested that the contractual H&S arrangement is the only construct which has a direct effect on project H&S performance. Mediation hypothesis testing was performed, and results were that attitude and selection of contractors based on their historical health and safety performance have an indirect effect of project health and safety performance. The study was limited to a selection of projects for a range of clients executed by a major construction contracting organization. The study highlighted the urgent need to change the traditional mind-set that H&S is the responsibility of the construction contractors alone.

Recycling addresses environmental issues associated with solid waste by minimizing overall resource consumption and environmental impact. In the construction industry, concrete recycling is crucial because concrete is the most dominant waste of construction and demolition waste. However, its implementation is at a low level in numerous countries becauseconstruction managers refuse to adopt concrete recycling in practice. This study’s objective is to identify factors that are affecting decisions in adopting concrete recycling from the constructionmanagers’ perspective. To achieve this objective, open-ended interview data with constructionmanagers are analyzed. Eleven factors affecting decisions in adopting concrete recycling inure identified. The factors are recycling factories, availability of raw material, quality, cost, reliable standard, government encouragement, legally, acceptance factor, proper planning, skilled workforce, and management. This research contributes to the body of knowledge in the analysis of factors that influence the acceptance of concrete recycling from industry practitioners’ perspectives, which could help researchers and industry practitioners develop strategies to reduce the rejection of concrete recycling among construction managers. The findings of this research would help improve the success of adopting concrete recycling in the construction industry.

Inflation and CO2 emission are the two most deleterious elements in the construction industry. However, so far no linkage between the two has been estimated. Therefore, this study examines the relationship between carbon dioxide (CO2) emission and the inflation rate in the construction industry of Malaysia and proposes a CO2 emission calculator framework. As it is not possible to calculate the effect directly, therefore, an indirect assessment of the correlation coefficient was performed between the inflation rate (independent variable) and construction rates, i.e., building material prices and value of construction work (dependent variables) along with percentage deviation of each variable. The results show that with a decrease in the inflation rate, the prices of the building materials also decrease, whereas the value of the construction work increases. The relationship looks attractive from an end-user perspective, but it creates a major problem of CO2 emission. The effect impacts directly on environmental sustainability as it is not suitable for the greenhouse effect because it triggers CO2 emission. While estimating how much CO2 emission occurs from the value of construction work of Malaysia, it was revealed that there is no such calculator available to perform the estimation. Therefore, a CO2 emission calculator framework is proposed, which will be beneficial after its practical implementation for the construction industry stakeholders and government/policy makers to monitor the emissions and control the adverse effects of massive construction work.

Effective communication among construction stakeholders has been a serious challenge in the global industry. Implementation of Building Information Modeling (BIM) has been established as a useful approach to overcome the challenge. However, lack of a single strategy for effective implementation of BIM tool during construction activities has made its application in a developing nation such as Nigeria to be very slow. Therefore, this paper aims to identify a single strategy that can be used to effectively implement BIM in Nigeria construction industry. This was achieved by conducting a mixed methods research in some selected construction firms located in Abuja the capital city of Nigeria in the year 2019. Interview and questionnaires were the main instruments used for data collection in the mixed methods research design. The findings of the study showed that BIM has not been maximally tapped by construction firms in Nigeria. The finding of the study also revealed that establishment of enforcement bodies that will ensure BIM application in every project is a significant strategy for BIM implementation in Nigeria construction industry. Such finding streamlined several strategies that can be used by project actors to understand the concept of BIM adoption in the study context. This could lead to affordable BIM projects delivery in Nigeria and consequently improve the performance of global construction industry. The study recommends that the underlying strategies that can be used to overcome the challenges of BIM enforcement in Nigeria construction industry should be investigated by prospective BIM researchers.

The study assessed response of Nigerian Construction Industry to economic growth of Nigeria. The research was conducted using secondary data. The secondary data used was the National Account Dataset from 1981 to 2018 as 2010 constant price year. This was gotten from the Central Bank of Nigeria (CBN) publication reports. The response was evaluated through Impact propensity (IP), Finite Distributed Lag (FDL) and the Long Run Propensity (LRP). These parameters were calculated from the time series regression analysis using ordinary Least Square Method of estimation. The results show that the impact propensity of economic growth on construction is weak with correlation coefficient of -0.012. Delayed impact of economic growth on construction was observed with finite distributed lag of two year cycle. Maximum correlation coefficient of 1.265 with the economics of the preceding year (t-1) was observed. Long run propensity of 1.333 establishes a high growth propensity for construction industry given a one percent permanent GDP growth. Therefore, the study concluded that a consistent economic growth is desirable so as to achieve improved construction industry contribution to GDP.

A major factor in climate change is the building industry, which is one of the leading producers of greenhouse gas emissions. Construction has a significant negative impact on the environment since it devastates habitats and extracts materials from priceless resources. Understanding the industry holistically and how the process, materials, and design all contribute to climate change can help to better comprehend its effects. Due to the rapid growth of the construction industry in the Maldives, there is various environmental impacts arise in the Maldives. Hence, the research aim was to minimize the environmental impact that occurred in the Maldives due to construction activities. Accordingly, the mixed-method research approach was selected. For the questionnaire survey, 150 professionals were selected as a sample and distributed the questionnaire survey. However, 117 responses were received for the questionnaire survey. Six numbers of professionals were selected as a sample for the qualitative approach. Accordingly, the study revealed that generation of inter waste, inert water, and inland water pollution, dust generation from construction activities chemicals pollution, increase land usage, operations with high potential soil erosion, water pollution, toxic generation, operations with vegetation removals, unnecessary building consumption, and shortage of natural resources are the main environmental impact occurred in the Maldives due to the construction industry. In addition to that, the study shows that lack of proper EMS process, lack of management level support, lack of proper guidance, and lack of knowledge regarding EMS by the stakeholders are the major problems in Maldives construction industry to implement and maintain proper environmental management system. Hence, this research identified by implementing proper rules and guidelines, enhancing the knowledge of stakeholders, adapting proper construction processes, adapting proper health and safety measures, and conducting awareness sessions and training sessions will lead to avoiding or minimizing the environmental impact and major problems mentioned above. Ultimately these strategies help to enhance the management of Maldives' environment.

Supply chain management concept has found its way into the construction sector of the economy as a result of the inherent opportunity to improve performance. The concept has continued to attract increasing support among major stakeholders in the execution of construction projects. However, it was observed that the strategy is still at low level of adoption among professionals in the industry. Moreover, the low level of knowledge of the strategy and the inability to effectively put the principles of supply chain management to practice hinders the application. This study therefore advances the knowledge of supply chain management by undertaking an examination of few key areas on the concept with a view to improving the awareness and understanding among professionals and assist in designing a supply chain management strategy suitable for building development process. Relevant studies were identified for review by literature search using key words and concepts related to the topic of the current study. Thematic areas of discussion include the construction industry outlook, building development process, the principles and essentials of construction supply chain management. The understanding of basic principles and essentials of supply chain management is important to adopting, adapting, designing and deployment of the strategy in the construction industry and this constituted the purpose and focus of the study.

This change in emphasis is noticeable partly because construction site waste management and minimization have rarely been planned for in the past few decades and ultimately may eliminate waste in the construction process. It has dramatically changed the urban landscape in recent times, especially in major cities in developed countries. Waste in construction occurs in a variety of ways, in a variety of forms, and in great magnitudes/degrees. For example, there are very few building operations that are absolutely waste-free. Contemporarily, reducing wastage across the building construction process has been discussed broadly in the scientific community by professionals in the built environment and of course by the general public. With the growing construction activities worldwide, it raises a swirl of questions, how did we get to this point, and are the alternatives more desirable? In answering this question, this paper identified and discussed extensively fifteen major distinct trends that are responsible for the wastage in building construction in most cities

One of the key indicators of the viability of the economy of any nation is the aggregate output of its construction industry. To this end, it is highly encouraged that significant investment portions of any country should be devoted to capital investment to spur development and ultimately boost the Gross Domestic Product (GDP). However, capital projects are usually attributed with the demands of enormous financial input, hence, due to low gross domestic savings, alternative source of financing such as foreign direct investment (FDI) as against the conventional government-sourced financing experienced in most developing countries is highly encouraged. In the light of the aforementioned, this study assesses the benefits of FDI in the South African construction industry. Construction professionals formed the population of the study, while the data elicited from the respondents was analysed with appropriate analytical tools. Findings from the study shows that the most significant benefits of the flow of FDI into the South African construction industry are technology transfer, enhanced productivity and human resource development. Conclusively, the study makes recommendations that would help in stimulating the flow of FDI into the construction industry in South Africa considering the inherent benefits as revealed in its findings.

The expansion of annual capital budget over the years without a corresponding increase in the volume and quality of infrastructural development in Nigeria has been attributed to those factors assumed to have great impact on the economic performance of the country. This study examined the effect of selected economic factors on the size of construction sector expenditure in Nigeria using economic data from 1981-2020. It employed econometrics statistics. The result revealed that there was a long-run co-integration among the variables with ARDL bound estimate values of F-stat. (7.40) and t-stat. (-6.56) respectively. These are higher than both the lower and upper bound critical values at 1%, 2.5%, 5% and 10% respectively. The result further revealed that exchange rate, oil prices, population, trade openness, foreign direct investment, unemployment rate, public debt and real GDP were important determinants of the size of construction sector expenditure in Nigeria. It also revealed that construction output, inflation rate, government revenue and taxation had trivial determinants due to issues relating to policy, management and execution of capital budget. The study suggested that government should make and implement apposite policies, and be diligent in allocation and management of public fund to ensure a sustainable economy through infrastructural development.

Old buildings are known to have poor energy performance and have limited improvement options as they approach their end-of-life. The demand for sustainable design and construction of new buildings and the desire to improve the performance of existing ones is rapidly increasing. Given numerous retrofit options available, it is imperative to determine which criteria should be used to arrive at a logical and impartial choice. Multifarious and conflicting factors such as environmental, economic, social, and technical performance further complicate the decision-making process. To address this, a systematic hybrid decision framework is developed to evaluate energy retrofit strategies and to identify a compromise retrofit scenario which considers all stakeholders involved. The Analytic Hierarchy Process (AHP) is used to determine the relative weight of each criterion based on stakeholders’ judgement while VIKOR is used to arrive at a compromise retrofit solution using relevant performance metrics. Although a Net-Zero Energy (NZE) scenario was proven technically feasible, this scenario was not identified as a compromise solution. Instead, three retrofit scenarios - on-site generation with high energy potential, mechanical/electrical with moderate energy potential, and building envelope with low energy potential showed good compromise for stakeholders. The proposed framework can be used as a tool by decision makers to arrive at compromise solutions that can benefit stakeholders.

Modular prefabricated construction has attracted global attention to meet increasing housing demands and infrastructural deficits owing to its construction speed and efficiency. Unfortunately, the benefits of such modular prefabricated structures are undermined by heavy steel utilization, which is susceptible to corrosion, and contributes to their heavy weight leading to transportation and erection problems during construction. Bioinspired lightweight sandwich CFRP composite reinforcement is investigated as an alternative to steel along with recycled concrete for sustainable prefabricated construction using a performance-based hybrid Taguchi-Response surface methodology multi-objective optimization approach. The optimized result exhibited improved mechanical properties and favourable, ductile failure mode attributed to the Bauschinger strain-reversal effects and composite actions of the bio-inspired CFRP reinforcements. Comparatively, the bioinspired sandwich composite reinforcement was found to be 0.73-4.4 times more cost-effective than steel reinforced concrete structures in terms of fracture toughness and has potential applications in lightweight prefabricated (modular) concrete structures. This study also revealed prevalence of behavioral, technical, infrastructural, market and legal barriers which hinder adoption of prefabricated construction and can be overcomed through appropriate regulatory framework, standards, centers of excellence, demonstration projects and incentives for advanced prefabricated construction. Government authorities should promote advanced prefabricated composite construction in new construction projects and future smart cities to minimize construction wastes and carbon emission problems prevalent in most cities, providing employment support to construction companies, improving safety/welfare training and encourage collaboration among construction firms to improve the resilience of the construction industry to Covid-19.

Companies of the construction sector face a significant impact on the environment and people: consume massive amounts of natural resources, emit pollutants, and generate large amounts of waste, are a place of danger and accidents at work. It is well established that implementation of CSR principles can lead to several economic, social, and environmental benefits. This is shown by numerous studies carried out in various countries among companies from different sectors of the economy. The aim of the article is to identify the most determining activity motives, barriers, and effects of implementing CSR principles by enterprises of the Polish construction sector and to determine the differences in this aspect between large, medium, and small-size enterprises. A questionnaire survey covered 177 enterprises. Factor like size, a place of origin, type of capital (domestic, foreign), annual turnover and time in the market were also considered. The documents of enterprises, reports, statistical data, and internal regulations of companies were also examined. The research results show large variations in terms of motives, barriers and expected benefits out of the implementation of CSR principles in various types of construction enterprises. There are different ways of implementing CSR principles and incorporating this area into organizational structures of the companies. A special role is assigned to large enterprises that show the greatest commitment in this scope. They become sources of good practices for other types of enterprises.

The construction sector exerts an exceptional impact on economic development all over the world. Adequate buildings and infrastructures made by the construction sector ensure that a country reaches certain targets like social development, industrialization, freight transportation, sustainable development, and urbanization. This study aims to determine the construction sector’s connectivity with other sectors through complex linkages that contribute immensely to the economy and gross domestic product (GDP). The data were collected from the Department of Statistics Malaysia and the World Bank from the year 1970 to 2019, and the Pearson correlation test, the cointegration test, and the Granger causality test were conducted. The vector error correction model (VECM) was created for short-term and long-term equilibrium analysis and impulse response function (IRF) was performed to study construction industry behavior. Afterwards, the forecasting was done for the year 2020 to 2050 of the Malaysian economy and GDP for the required sectors. It was revealed that some sectors, such as agriculture and services, have forward linkages while other sectors, such as manufacturing and mining, are independent of construction sector causality, which signifies the behavior of the contributing sectors when a recession occurs, hence generating significant revenue. The Malaysian economy is moving towards sustainable production with more emphasis on the construction sector. The outcome can be used as a benchmark by other countries to achieve sustainable development. The significance of this study is its usefulness for experts all over the world in terms of allocating resources to make the construction sector a sustainable sector after receiving a shock. A sustainable conceptual framework has been suggested for global application that shows the factors involved in the growth of the construction industry to ensure its sustainable development with time.

Indian construction industry has not been addressed adequately in the context of green supply chain practices. However, various drivers, enablers and barriers for adoption of green supply chain practices have been reported in the literature. In view of these stylists facts, the main aim of the present research work is first to investigate the adaptability of green supply chain practices by various categories of Indian construction companies followed by identifying the correlation of drivers, enablers and barriers with the construction industry readiness of adaptation of green supply chain practices. Finally, these drivers, enablers and barriers are prioritized by using the AHP methodology. A questionnaire survey was disseminated to senior construction project managers of Indian construction companies having different size as well as area of operations. Preliminary analysis is performed by using the descriptive statistics. Four hypotheses are tested using ANOVA and spearman’s correlation coefficient. The priority structure of drives, enablers and barriers is also developed by using the AHP methodology. Results demonstrate that institutional theory, complexity theory, ecological modernization theory, resource-based view and resource dependency theory are well supported. The study will be helpful for the construction project managers/clean production policy makers in taking more informed, systematic and efficient decisions, while adapting the sustainable supply chain practices in the context of construction industry.

The growth of urban areas is one of the major factors that leads to cutback of vegetation. This paper is set to assess the effect of urbanization on vegetation cover in the Minna metropolis, Niger State, Nigeria. The remote sensing Quick Bird satellite images of Minna for the year 2010, 2015 and 2020 were used to obtained land use information change. Remote Sensing Data Image (RSDI) was processed using GIS Arc Map 10.1 for digitization and calculation of built-up areas and the land use change. Two neighborhoods were chosen for examination and analysis, Tayi village neighborhood and old Advanced Teachers’ College (ATC) layout; presently called Zarumai New Extension Neighborhood, all in Minna, Nigeria. It was found that study areas have grown double between 2010 and 2020, speedy urban development due to population increase led to massive de-vegetation, as at 2010 the built-up area in Tayi was 20%, but by 2020 built up area has increased to 46% while in old ATC in 2010 was 30.8% but as at 2020 the built-up area has grown to 82.8%. Research limitation/implications: In evaluating the influence of urbanization on vegetation in the study areas, selected neighborhoods were examined by segmenting eleven years into two at the interval of six years and five years, that is, 2010 to 2015 and 2016 to 2020 respectively. Therefore, the gradual effect of urbanization on vegetation was examined from 2010 to 2020. The study revealed that, the method of land acquisition is through customary and informal purchase, less concentration was given to open space development and management and the relationship between built up areas and vegetation cover was opposite, as built-up areas enlarged, the vegetation covers decreased.

The study assessed-excusable delay (NEDs) factors affecting contractors' performance in project delivery in Akure metropolis, Ondo State, Nigeria. A structured questionnaire was used to obtain data from consultants, contractors, architects, and quantity surveyors from a sample of one hundred respondents using convenience and snowball sampling techniques. The study used descriptive statistic to explain the demographic characteristics of the respondents; relative important index (RII) for ranking of factors based on the perception of the respondents as well as the Kendall's coefficient of concordance and Kruskal-Wallis (KW) Test for the hypotheses. The findings revealed that there is an existence of NEDs factors in Akure Metropolis. Also, from the findings, there is a significant degree of agreement among the respondents regarding the NEDs factors affecting contractors' performance in project delivery in Akure metropolis, (p-value (sig) < 0.05). Similarly, there was no significant difference in the perception of the respondents (p-value > 0.05). Thus, contractors must be active in the utilization of finances, time, and human resources as identified as causes of NEDs, as this will help to mitigate delays in project delivery.
