Estimating is a fundamental part of the construction industry. The success or failure of a project is dependent on the accuracy of several estimates through‐out the course of the project. Construction estimating is the compilation and analysis of many items that influence and contribute to the cost of a project. Estimating which is done before the physical performance of the work requires a detailed study and careful analysis of the bidding documents, in order to achieve the most accurate estimate possible of the probable cost consistent with the bidding time available and the accuracy and completeness of the information submitted. Overestimated or underestimated cost has the potential to cause loss to local contracting companies. The objective of this paper is to identify the essential factors and their relative importance that affect accuracy of cost estimation of building contracts in the Gaza strip. The results of analyzing fifty one factors considered in a questionnaire survey concluded that the main factors are: location of the project, segmentation of the Gaza strip and limitation of movements between areas, political situation, and financial status of the owner.

The idea of implementing supply chain management (SCM) principles for the construction industry was embraced by construction stakeholders to enhance the sector's performance. The analysis from the literature revealed that the implementation of SCM in the construction industry enhances the industry's value in terms of cost-saving, time savings, material management, risk management and others. The construction supply chain (CSC) can be managed using the pull or push system. This chapter also discusses the origin and proliferation of SCM into the construction industry. The chapter revealed that the concept of SCM has passed through five different eras: the creation era, the use of ERP, globalisation stage, specialisation stage and electronic stage. The findings from the literature revealed that we are presently in the fourth industrial revolution (4IR) era. At this stage, the SCM witnesses the adoption of technologies and principles driven by the 4IR. This chapter also revealed that the practice of SCM in the construction industry is centred around integration, collaboration, communication and the structure of the supply chain (SC). The forms and challenges hindering the adoption of these practices were also discussed extensively in this chapter.

Stakeholder management plays a significant role in successfully delivering construction projects. However, being able to carry out effective stakeholder management in construction is contingent upon understanding the interrelationships among critical success factors (CSFs) for stakeholder management in construction and how they are related to project success (PS). This would enable the persons responsible for stakeholder management to know the logical process for addressing the CSFs in order to get stakeholder management right. The understanding of this relationship has not been addressed. The purpose of this paper is to investigate the interrelationships between the CSFs for stakeholder management and PS in construction.

From an extensive literature review, 23 CSFs for stakeholder management in construction were identified. A conceptual structural equation model (SEM) of the relationships between CSFs was developed (including measurement and structural models) using the groupings of the CSFs for stakeholder management in construction. A questionnaire survey was used to collect data from construction industry practitioners. The data so collected were analysed using SEM in analysis of moment structures (AMOS).

The SEM analysis of data collected resulted in the best fitting measurement model comprising 16 CSFs as indicators of four latent variables, namely, stakeholder characteristics and project characteristics (SCPC); stakeholder analysis (SA); stakeholder dynamics (SD); and stakeholder engagement/empowerment (SE). Furthermore, it was found that only SE has a direct positive impact on PS. The other three constructs SCPC, SA and understanding SD collectively impact on PS through the construct, SE.

The research reported in this paper was carried out in the UK; hence, the findings may have portrayed the UK construction professionals’ opinion. However, the theoretical principles on which the research was based are general and similar research could be replicated in different countries whose construction procurement processes and industries are structured like those of the UK or otherwise.

The main contribution of this study to existing knowledge is an empirical evidence of the interrelationships among the CSFs for stakeholder management in construction through their latent variables which is portrayed in the best fitting structural model showing the relationships between the constructs of CSFs for stakeholder management and PS. This should serve as a guide to construction project management team or responsible professionals for undertaking stakeholder management in construction projects.

The paper contributes to theory by empirically identifying the interrelationships among the CSFs for stakeholder management linking to PS which will serve as a guide to construction professionals.

Benchmarking can be an effective way of helping organizations to deliver better services through continuous improvement. The concept of benchmarking has been extensively applied to the construction industry in recent years to enhance the performance of the project delivery process. Success is hard to achieve, especially for a construction project delivered by an innovative procurement method – design and build, and the identification of critical success factors can enable project team leaders to make improvements in some particular areas. This paper aims to establish a conceptual framework of critical success factors (CSFs) for design‐build projects in construction. From the framework, it is hypothesized that project success of a design‐build project is a function of the interaction among project characteristics, project procedures, project management strategies, project‐related participants, project work atmosphere and project environment. The CSFs so identified can provide practitioners and academics with a better understanding of running a design‐build project successfully to develop a benchmark for the D&B project delivery process.

The purpose of this paper is to identify the critical success factors (CSFs) and key areas for improvement for public–private partnerships (PPP) in affordable housing schemes (AHS) projects, using Tanzania as a case study.

Semi-structured interviews were conducted with 10 public and private sector practitioners in Tanzania. The collected data and the interview transcripts were analysed using the standard qualitative analysis technique of content analysis.

The findings show the six most important CSFs as: a dedicated team of professionals to oversee the PPP projects, official and unofficial site visits and inspection, government support and guarantees, undertaking checks and balance from the design stage to construction stage, scrutiny of PPP project proposal and trust and integrity. The mapping of the CSFs across the PPP project lifecycle highlighted a higher incidence across the following phases: building (n = 11), preparation (n = 10) and operational (n = 9).

The identification of these CSFs would support PPP practitioners in successfully implementing PPP in AHS; besides, there is potential for their inclusion in the future development of the affordable housing PPP conceptual framework. Therefore, based on the identified CSFs, both the government and policy makers could use the findings as the basis for re-examining the existing PPP policy and regulations and reflecting on the existing situation with a view to improving the delivery of future PPP projects.

This paper provides the first empirical study by applying direct content analysis to identify and understand the CSFs and key areas for improvement for PPPs in AHS within the Tanzanian housing sector. This is rather an under researched subject around CSFs for PPPs from developing countries such as Tanzania.

The purpose of this paper is to report the findings of research into the levels of awareness, usage and benefits of risk assessment and management practices (RAMP) within the construction industry in Ghana.

The study was conducted through a structured questionnaire administered to 103 construction professionals practising with construction client (private and public), consultant and contractor organisations within the Ghanaian construction industry. The results were analysed to establish the current levels of awareness, usage and perceived benefits of risk management practices. Survey response data were subjected to descriptive statistics; subsequently, ANOVA and other non-parametric tests were used to examine the differences in the levels of agreement of the perceived benefits.

This study illustrates that although the majority of the respondents are aware of RAMP, some professionals found the process not to be formal. Relative to the benefits, there was a disparity in the ranking of agreement scores on two of the eight benefits among the respondents in relation to “product to the required quality” and “reduction in contract claims”. However, they all agreed on “improved team morale” as the most important benefits.

The research limitation of the study is that the cross-sectional data made it difficult to generalise the findings. Geographically, only respondents from construction organisations in the Greater Accra Region were considered. However, it is recommended that future work on RAMP be extended to cover all the regions of the country.

The findings of the study provide practical for organisations to measure the benefits and capture the awareness of risk management practices through the provision of a framework based on an index and scoring method. This can be used by senior management in assessing the current benefit levels within projects “internal benchmarking” and has potential for external benchmarking purposes. Furthermore, through education and training, both formal and informal process including more information and provision of expertise within RAMP could enhance the levels of awareness.

Little is known about the current levels of awareness, usage and benefits of risk management among Ghanaian construction organisations, and this study provides some insights and deepening our understanding on the uptake and perceived benefits of RAMP among construction professions in Ghana. These findings may help construction practitioners in having an increased awareness of risk management practices, and this can further lead to a higher uptake and usage resulting in reaping the advocated benefits of the implementing risk management practices such as achievement of project objectives of time, cost and quality, as well as enhanced decision-making processes.

In this chapter, the nature and extent of corruption in the construction industry is considered from a worldwide perspective, but particularly in the context of research conducted in South Africa. The definition of corruption is expanded to include conflict of interest and unethical conduct. Corruption in the construction industry is found to be universal and pervasive, occurring in all areas, at all stages, at all levels, and in all forms. A simple triangular model of corruption is replaced by a more complex four-dimensional risk-based model. The challenge for the construction industry, in combating corruption, will essentially require multilateral action in all four dimensions of the enhanced model: eliminating and reducing opportunities where possible; relieving the pressures to commit corrupt acts; rebutting the rationales and arguments used to excuse corruption; and substantially improving and innovating more forensic methods of detection. While the decision to engage in corruption is risk-based, particularly in terms of the capacity to evade detection; in essence corruption is a cultural and moral issue for society.
