Cloud Computing as a Construction Collaboration Tool for Precast Supply Chain Management
Abstract and Figures
Precast construction projects are characterized by many activities, the involvement of numerous parties, a lot of effort and enormous processes. Precast supply chain phases are classified as: planning, design, manufacturing, transportation, installation and construction. Achieving integrated construction requires the parties within the precast supply chain phases to have efficient communication and effective collaboration to deliver proper and up-to-date information. The aim of this research is to explore cloud computing technology as the construction collaboration tool and to propose the cloud system architecture for precast supply chain management. The findings in this research are based on a comprehensive review of supply chain management, cloud computing and the precast industry. Findings illustrate that the major obstacles to precast construction are: poor planning and scheduling, less flexibility in design, production lead time, heavy precast components and poor on-site coordination. These obstacles could contribute to the negative consequences for the efficiency and effectiveness of precast project delivery. Therefore, cloud computing technology has valuable potential to mitigate these obstacles and deliver an effective collaboration system within the precast construction industry.

Keterlambatan proyek konstruksi sering kali terjadi akibat berbagai faktor, seperti perubahan gambar kerja dari pihak developer, keterlambatan pembayaran, serta perubahan volume Rencana Anggaran Biaya (RAB) yang disebabkan oleh adanya pekerjaan tambahan. Penelitian ini menggunakan pendekatan kualitatif dengan metode wawancara dan analisis dokumen untuk mengidentifikasi faktor penyebab keterlambatan serta dampaknya terhadap estimasi biaya dan waktu penyelesaian proyek. Hasil analisis menunjukkan bahwa keterlambatan proyek tidak hanya menyebabkan peningkatan biaya tenaga kerja dan material tetapi juga memperpanjang durasi penyelesaian pekerjaan secara keseluruhan. Penerapan metode earned value mengungkapkan bahwa nilai Cost Performance Index (CPI) berada di atas 1, yang menunjukkan bahwa biaya aktual lebih rendah dibandingkan anggaran yang direncanakan. Namun, Schedule Performance Index (SPI) dalam beberapa minggu menunjukkan angka di bawah 1, yang menandakan adanya keterlambatan dalam penyelesaian proyek. Temuan penelitian ini menekankan pentingnya perencanaan yang lebih matang, koordinasi yang lebih efektif antara tim proyek dan developer, serta perbaikan sistem persetujuan pembayaran guna mencegah keterlambatan di masa mendatang. Dengan menerapkan strategi mitigasi risiko dan manajemen proyek yang lebih baik, proyek konstruksi diharapkan dapat berjalan lebih efisien dan sesuai dengan target yang telah ditetapkan.
... Understanding the importance of collaboration is imperative for every project manager since it eliminates ambiguities, uncertainties and risks commonly identified within construction projects, as endorsed by Walker, Davis and Stevenson (2017). Abedi et al. (2014) also revealed that construction management must include cloud-based real-time project planning. Chang, Cui and Zhong (2012) added that real-time monitoring and modelling are used to anticipate and analyse the building timeline. ...
The construction industry is confronted with persistent challenges in the enhancement of project planning and collaboration to enhance efficiency and performance. Nevertheless, recent technological advancements have introduced cloud-based real-time collaboration (CRTC) tools as promising solutions for streamlining project planning processes. The objectives of this research are: (1) to investigate the current adoption and tools of CRTC in the construction industry within the project planning phase, (2) to identify the implementation of construction projects that adopted CRTC and (3) to analyse the critical success factors that contribute to the adoption of CRTC in the construction industry. The quantitative method was employed, utilising a structured questionnaire survey to gather data from 120 respondents who represent various construction industry players. The research findings highlighted that the current adoption is “moderately familiar” with CRTC in the construction industry and the implementation of construction projects is “significantly better” when CRTC is adopted. Five key factors impact the successful adoption of CRTC tools into construction project planning processes: (1) top management support, (2) budget and cost, (3) data security and privacy, (4) compatibility and (5) perceived industry pressure. By comprehending and identifying these factors, construction stakeholders can develop targeted strategies to effectively expedite the adoption of CRTC tools. Furthermore, this research contributes to the expanding body of knowledge on digital transformation within the construction industry and provides valuable insights for decision-makers, project teams and technology providers. The research was aligned with the Construction 4.0 Strategic Plan (2021–2025), Malaysian Digital Economic Blueprint and Sustainable Development Goals no. 9. Additionally, the outcomes of this research have the potential to cultivate a collaborative environment within the construction industry, resulting in improved project planning and execution, reduced project delays and enhanced overall project outcomes.

While initial costs in building economics cover a small portion of the costs incurred during its life-cycle, most occur in construction, operation, and subsequent processes. Despite its numerous contributions to building economics, the construction industry is slowly adapting to digital technologies. To overcome the barriers and crown the assets with their proper management, dynamic applications of digital tools and techniques of Industry 4.0 need to emerge in the construction industry. Therefore, this study aims to present an integrative approach that combines quantitative and qualitative analysis techniques to critically review the available literature on the potential contributions of digital construction technologies to building economics through the post-design phases of the life cycle. The primary focus of the investigation is how digital technologies can overcome prevalent problems and how they can impact building economics. The study contributes to the field by providing an awareness that will inform researchers and practitioners of the trends, gaps, and more profound exchange of ideas in future research efforts.

This article takes the relevant construction supply chain (CSC) literature of the Web of Science Core Collection Database in the past 20 years and its construction supply chain - blockchain as the object, and then aims to identify and analyze the articles related to the application of blockchain technology in the CSC, and analyze the related problems and potential of the CSC in the application of blockchain technology. An analysis and exploration of a total of 395 articles was conducted. Through VOS viewer software, the author in collaboration network, key term co-occurrence network, and theme classification visualization network of the research field are extracted. The research status of blockchain technology in the CSC is analyzed, and the two key issues of the CSC are focused on through literature reading, so as to explore the application prospects of blockchain technology, and make relevant discussions and some application prospects for the application of blockchain technology in the future.
Supply chain (SC) networks now need to submit structural adjustments to respond to events like natural and unanticipated disasters that tend to cause interruptions and damage the continuity of business operations. Artificial intelligence, robotics, blockchain, 3D printing, 5G, and the Internet of Things are just a few examples of disruptive technologies that are being widely used and will drastically alter how SCs sustainability is conducted in the real world. The sustainability of SC operations can be greatly enhanced by disruptive technology. Organizational competency is needed to strike a balance between sustainability and SC disruption. Sustainable SCs may not have enough resilience to survive disruptive events since they prioritize efficiency and economic aspects. That is why sustainable SC management studies trends toward disruption utilizing new technologies. To adapt SCs to the needs of contemporary manufacturing processes, innovations in environmental conservation and social development have been put into place. In contrast, even though the fact that sustainability and disruptive technologies have each been extensively examined separately, few suggestions combine them in the measuring of SC performance. Since there are not any studies in the literature that identify the influence of disruptive technologies on SC sustainability generally, in this research we concentrate on several disruptive technologies that are used to provide SC sustainability. The objective of this work's suggestion is to provide a framework that integrates multi-criteria analysis methods with neutrosophic theory to evaluate the influence of disruptive technologies on the sustainability of SCs. This framework is an integration of the α-discounting technique for multi-criteria decision-making (α-D MCDM) and the Vlse Kriterijumska Optimizacija Kompromisno Resenje (VIKOR) method. The new α-D MCDM approach overcomes the analytical hierarchy process's (AHP) method limitations of pairwise comparison to n-wise comparisons and also deals with inconsistent problems. SC sustainability has three main criteria which are economic, environmental, and social, their weights are measured using α-D MCDM with n-wise comparison. Also, the twenty sub-criteria weights were evaluated using the standard AHP method with consistent comparison. To rank the disruptive technologies that influence SC sustainability, we utilize the VIKOR method. The proposed framework is applied under a neutrosophic environment to ensure more accurate results and deal with uncertainty and vague conditions. Finally, sensitivity and comparative analyses were performed to confirm the verity, strength, and stability of the enhanced methodology.
The objective of this study is to ascertain the essential elements that contribute to the successful implementation of cloud computing in small-scale construction projects, with the ultimate goal of promoting intelligent development in Malaysia. The construction sector is undergoing rapid transformation, and the integration of cloud computing technology can make a substantial contribution to the achievement of project objectives and the promotion of sustainable development. Nonetheless, there exists a dearth of comprehension regarding the function of cloud computing in minor construction undertakings within the Malaysian context. In order to bridge this gap, a mixed-methods approach was implemented, which encompassed a comprehensive review of the literature, interviews with experts, and a preliminary survey that involved 160 participants. Utilizing the findings of the pilot survey, the process of Exploratory Factor Analysis (EFA) was employed to discern and eliminate nonessential determinants of success. A survey utilizing primary questionnaires was conducted with a sample size of 230 participants. The subsequent analysis of 16 critical success factors was carried out through the application of Structural Equation Modeling (SEM). The findings indicate that there are four fundamental constructs that play a crucial role in the effective execution of a project. These include cost, quality, and time management (β = 0.352); planning success (β = 0.360); organizational success (β = 0.351); and communication and coordination (β = 0.299). The research results have favorable ramifications for the construction sector in Malaysia. The integration of cloud computing technology in minor construction endeavors has the potential to augment project efficacy and foster sustainable development. This study offers a roadmap for stakeholders in the construction industry to effectively utilize cloud computing technology for smart development by identifying critical success factors.
The construction industry utilizes a substantial number of resources, which has negative impacts on both environmental and socioeconomic aspects. Therefore, it is important to reduce these negative impacts and maintain sustainable development (SD). Recent studies suggest that integrating Industry 4.0 (also called Construction 4.0 (C4.0) in the construction industry) and SD may help address these concerns, which is a new and ever-evolving field. In order to fully understand SD in the C4.0 context, this paper offers a verifiable and reproducible systematic literature review and bibliometric analysis of associated topics. Through a review of 229 works, this article presents the publication trend, the most prolific journals, countries, institutions, researchers, and keywords analysis , as well as the content analysis of C4.0 impacts on SD based on triple-bottom-line (TBL) dimensions. The authors also identify and summarize the critical success factors (CSFs) of C4.0 toward SD. Overall, findings reveal the potential benefits of C4.0 on SD and contribute to the evaluation of sustainable C4.0 innovations. The key topics and CSFs identified in this work could potentially serve as the basis for future investigations, encouraging and directing interested researchers, and thus supporting both theoretical and practical progress in this evolving research area.

BIM is a complex technology. Although its potential benefits are clear, its integration in structural engineering firms requires leadership and persistence as well as careful planning. Sophisticated three-dimensional parametric modelling software for precast concrete structures has been commercially available since 2005. Early adopters have gained sufficient experience with precast concrete buildings to allow analysis and comparison of their adoption strategies. Four detailed case-studies, observed at two mid-sized engineering firms in the last two years, have been recorded and analysed. They shed light on the obstacles that had to be overcome, the achievements and disappointments, and the changes in workflow and personnel that the firms have experienced. The results reveal clear improvement in engineering design quality, in terms of error-free drawings, and steadily increasing improvement in labour productivity. The firms' clients have also begun to exploit the rich information available with BIM, but not to the extent expected. Progress in adopting BIM is slow but certain. The conclusions may help the managers of structural engineering firms who are planning their own adoption process to avoid some of the pitfalls of replacing 2D CAD practices with BIM.
Since construction is considered as one of the main sources of environmental pollution in the world, the level of knowledge and awareness of project participants, especially project managers, regarding the construction impacts on the environment are required to be enhanced. The aim of this paper is to develop a prototype of a Sustainable-Construction Planning System (SCPS) in order to mitigate the negative impacts of the construction industry on the environment. To achieve this aim, frequency and severity of known environmental impacts of construction process of residential buildings were investigated through interviews with a safety expert panel in Malaysia. Then, risk level associated with each environmental impact was calculated based on the relevant risk matrix. The SCPS extracts current construction activities from any computer-based schedule (Microsoft Project® in this study) and identifies sustainable strategies, and environmental impacts related to each activity as a report. The SCPS was presented to an expert panel who was asked to assess the reliability and usability of the SCPS. It can be concluded that the SCPS is efficient and helpful in mitigating construction related impacts on the environment. The practical implication of this study is to promote sustainable construction by promoting the project participants' knowledge and awareness of significant environmental impacts related to construction operations. This study could be a platform for developing automated sustainable planning systems that can be used broadly in construction projects.

The reasons precast concrete systems are not used extensively in the United States were explored through four mail surveys that were sent to 100 contractors, 100 design firms, 100 precast concrete manufacturers, and 100 local labor unions. The findings indicate that most of the prerequisite conditions for the extensive use of industrialized building systems already exist. The findings also indicate, however, that there is a major shortage of expert personnel capable of designing and organizing projects involving precast concrete systems and that almost half the contractors surveyed did not observe significant cost savings when they used precast concrete systems. Architects' and engineers' awareness of precast concrete systems and the number of competent precast concrete designers and erectors can be increased by providing adequate exposure of engineering and architecture students to these systems and by providing frequent and numerous continuous education programs for the benefit of active professionals.
