Leaders who lack leadership energy may struggle to demonstrate sustained competence and achieve effectiveness in difficult leadership situations. This research investigates the sources of leadership energy and examines the impact of leadership energy on the development and sustainability of leadership effectiveness and competence. This study employ...

Individuals and their leadership competencies have been the sole focus of project leadership research, rather than the project leadership’s behaviour and functions in project and organisational settings. As a result, this study investigates the project leadership functions and behaviours required for various project and organisational situations in...

This study aims to examine whether ready-mixed concrete (RMC) production in Nigeria is sustainable. This study proposes that RMC production will be sustainable, assuming the RMC plant, RMC products, plant management, RMC supply, RMC quality, and demand for RMC are sustainable. Based on a constructivist worldview, the proposition of RMC production’s...

INTRODUCTION Productivity is the efficiency in the process of transforming inputs (i.e. Labor and capital) into outputs (i.e. goods and services). Thus, productivity growth implies the ability and capacity to produce more goods and services from the same amount of inputs i.e. labor, capital, land, energy, etc. So, improved productivity can generate...

Scotland currently has 76·7% of all implemented timber-framed buildings in the UK housing market. England's figure is 16%. The English contribution is considered relatively low given its demand for more sustainable, low-cost social housing. The aim of this study is to investigate potential contemporary barriers to the adoption of timber as a primar...

Traditional methods of design are becoming less relevant and prevalent, due to institutionalising of Building Information Modelling (BIM) within statutory regulations and the huge amount of data that BIM presents to practice; especially in 3D models. This can be seen in the A1 Dishforth-to-Barton road infrastructure improvement scheme which compris...

The recycling of steel chips into an environmentally friendly, responsive, and profitable commodity in the manufacturing and construction industries is a huge and difficult challenge. Several strategies designed for the management and processing of this waste in developed countries have been largely unsuccessful in developing countries mainly due t...

The majority of the sandcrete blocks used in the Nigerian building industry fall short of the minimum specification standards. There is evidence to suggest a wide variation in compressive strength from one block manufacturer to another and also within block samples from a single source. This problem has been attributed to poor quality control and s...

The state of infrastructure and services is widely perceived as a measure of development and a major catalyst for growth in both developed and developing economies. However, financing, maintaining and replicating existing infrastructures in areas of need have been mostly ineffective. In view of the widespread failures and poor state of infrastructu...

The high failure rate of infrastructures around the world is alarming, most especially when such failures constrain economic growth and development. In most cases, existing institutions or strategies designed to maintain and reproduce effective infrastructures in areas that lack them have been mostly unsuccessful, particularly in sub-Saharan Africa...

The current extensive use of low priced fine aggregate (sand) deposits in sandcrete block making in Nigeria is of concern because there appears to be a level of ignorance surrounding their existing properties and implications. To this end, silt contents and some grading parameters of the most commonly used fine aggregate deposits in parts of midwes...

One of the major outcomes of the present ailing social and economic conditions in sub-Saharan Africa is the enormous waste of resources due to project delay and cost escalation in the region. This paper critically analyses the causes and effects of project delay and cost escalation in sub-Saharan Africa taking Nigeria as a case study. The major cau...

The high failure rate of most infrastructures in sub-Saharan Africa is alarming, particularly in Nigeria, where the dearth and deterioration of infrastructure constantly imposes severe constraints on economic growth and development. Consequently, existing institutions or strategies which are designed to reproduce effective infrastructures in areas...
