The purpose of this paper is to report on primary research findings that sought to investigate and analyse salient issues on the implementation of 5D building information modelling (BIM) from the UK contractors’ perspective. Previous research and efforts have predominantly focussed on the use of technologies for cost estimation and quantity takeoff within a more traditional-led procurement, with a paucity of research focussing on how 5D BIM could facilitate costing within contractor-led procurement. This study fills this current knowledge gap and enhances the understanding of the specific costing challenges faced by contractors in contractor-led projects, leading to the development of 5D framework for use in future projects.

To develop a fully detailed understanding of the challenges and issues being faced in this regard, a phenomenological, qualitative-based study was undertaken through interviews involving 21 participants from UK-wide construction organisations. A thematic data analytical process was applied to the data to derive key issues, and this was then used to inform the development of a 5D-BIM costing framework.

Multi-disciplinary findings reveal a range of issues faced by contractors when implementing 5D BIM. These exist at strategic, operational and technological levels which require addressing successful implementation of 5D BIM on contractor-led projects adhering to Level 2 BIM standards. These findings cut across the range of stakeholders on contractor-led projects. Ultimately, the findings suggest strong commitment and leadership from organisational management are required to facilitate cost savings and generate accurate cost information.

This study highlights key issues for any party seeking to effectively deploy 5D BIM on a contractor-led construction project. A considerable cultural shift towards automating and digitising cost functions virtually, stronger collaborative working relationship relative to costing in design development, construction practice, maintenance and operation is required.

By analysing findings from primary research data, the work concludes with the development of a 5D BIM costing framework to support contractor-led projects which can be implemented to ensure that 5D BIM is successfully implemented.

The purpose of this paper is first to examine the effect of client-led and contractor-led supply chain initiatives on project performance in the Indian construction industry and second to assess how the client-led supply chain initiatives complement the contractor-led supply chain initiatives.

In this study, the effects of the client-led supply chain initiatives (reward power and competence trust of the construction clients) and the contractor-led supply chain initiatives (contractor integration and calculative commitment of the contractor) on project performance in construction projects are examined. The data were collected from 346 construction professionals working in Indian construction projects using purposive sampling. The proposed hypotheses were tested using structural equation modeling.

The contractor-led supply chain initiatives, in the form of contractor integration and the calculative relationship commitment of a contractor, were found to be strong mediators, indirectly affecting the project performance. On the other hand, the client-led supply chain initiatives, in the form of the reward power of the client and the competence trust of the client, directly influence the project performance.

This study reports the inevitable bias on the part of participants, who responded to the survey either in the capacity of client or contractor, although they might have executed projects in both capacities. Future studies could benefit from the use of objective data instead of behavioral data.

This study helps construction firms understand how to demarcate the client and contractor roles in the construction supply chain to improve the project performance.

The originality of this study lies in its investigation of the influence of client-led supply chain initiatives and contractor-led supply chain initiatives on project performance.

As clients have become more aware and demanding of the construction industry, they are also becoming less tolerant of the problems and the risks involved in the delivery of major projects. Presents a case study of design management within a design‐construct organization on a large residential apartment project. Identifies and analyses issues concerned with the organization, responsibilities, relationships and stages of development in a typical design‐construct project.

Lack of strict compliance to the principles of total quality management (TQM) by construction organizations has brought about poor quality of the finished building projects. This has been blamed for the incessant structural failure reported in Nigeria. This study appraised TQM implementation in the Nigerian construction industry, with a view to mitigating structural failure rate of construction projects. To achieve this aim, the study aims to assess the practice level of TQM and the factors hindering TQM implementation on construction projects.

The study utilized a well-structured questionnaire and convenient sampling method in the gathering and sampling of data among construction professionals in Imo state, Nigeria. Data analyses were done using, frequency, percentage, mean analytics and Pareto analysis.

The study revealed that major practice of TQM principles with respect to structural failure rate are purchasing: ensuring the procurement of materials of the specified quality standard, ensuring the use of a quality improvement construction process of the organization, site management responsibility: this entails ensuring quality supervision by the project management leadership and monitoring and control of quality during the construction to guarantee firm observance quality standards. Also, the major factors hindering TQM implementation on construction projects are: inadequacy of the necessary machineries, equipment, tools and facilities for the effective execution of work on construction site; breakdown in communication and information exchange between the management and supervisory teams on site; poor attitudes and strategies toward maintenance of equipment, tools and machines; and absence of prompt salary and incentive payment. It was recommended that construction firms must require the suppliers of construction materials to strictly comply with quality specification evidence in quality certification of delivered materials to mitigate structural failure.

This study appraised TQM implementation in the construction industry of Nigeria, with emphasis on Imo state. The study underscores the practice level of TQM and the key factors hindering TQM implementation on construction projects. Following the localized geographical limitation of the study area, a similar research in other part/states of Nigeria or even in other developing countries of African is necessary.

The practices level of TQM and the factors hindering TQM implementation were identified. This will be useful in guiding construction firms, other industry's key stakeholders and regulatory agencies in bringing about a sustainable quality management system for improve profit and value maximization and avoiding incessant structural failure.

This is one of the few studies that have assessed the practice level of TQM and the factors hindering TQM implementation on construction projects in Nigeria. This study took place in Imo state with records of periodic structural failure and building collapse.

Managing megaprojects is challenging due to their inherent complexity and uncertainty. Collaborative project delivery models have been introduced as an alternative to traditional project management in public infrastructure megaprojects and are often realized through collaborative contracts. These project organizations act as institutional arenas for logic interaction as actors with differing institutional backgrounds interact within the project. This paper aims to study the delivery phase of three megaprojects through an institutional lens, investigating the institutional interaction and alignment of logics therein.

A multiple case study was employed to reach deep insight into the phenomenon. Sixty-one interviews were conducted over 3 cases with representatives from all levels of the project hierarchy. Respondents were selected through snowball sampling. In two cases, observations of the shared project office were conducted. Data analysis built on first-order codes and second-order themes, collected into a theoretical framework.

The empirical evidence demonstrates the dynamics shaping institutional logics and gives evidence for changing logics in projects with a well-applied collaborative contract. However, there is a risk of resistance and a return to traditional logics since institutional change is slow and an unsuitably applied collaborative contract can lead to adherence to the conventional way of work.

Current research has focused on the regulatory framework and procurement phase of such models, but little attention has been given to the delivery phase and the interaction of conflicting logics. This paper can serve as an exemplar of the different logics found within public infrastructure projects and their interaction and alignment. Contributions include a heightened emphasis on the start of the project as a meeting point for differing institutional logics and the role change necessary when using a collaborative contract.

Failing to effectively play their leadership role can have a devastating effect not only on leaders, but also on the group or team they are responsible to lead, as well as on the organization or organizations they belong to and/or serve. In the following example of a leadership failure, the author’s inability to come to the plate to play her required role as a leader had a negative impact on her professional standing, as well as on a number of individuals who she was called to lead. This example illustrates the necessity to master “leading oneself” prior to leading others. Cleaning out the cobwebs in one’s own psyche and mastering emotional intelligence are pre-conditions for effective leadership. This is especially true when leading in a foreign cultural context as this chapter shows. A leader always faces the possibility of having to deal with individuals who bring out those inner parts of oneself that have not yet been dealt with and healed. This chapter focuses on the importance of the key ingredient of leading oneself, namely emotional intelligence. Within emotional intelligence, the author examines her leadership failure in relation to self-awareness and self-regulation while leading a US government foreign assistance project. She highlights the negative impact on her leadership of fear that arose from unresolved past conflicts remaining in my shadow side. “Self-betrayal” emerged as a key factor also in her leadership failure.

Demonstrates to the advanced FM professional, who is responsible for large construction projects, how to create a partnering relationship in the planning and construction process. Claims that effective partnering between the three major players – owner, architect and the general contractor – leads to successful projects where claims are minimized and eliminated. The concept of partnering replaces the historically adversarial environment inherent in most projects. Discusses examples of partnering agreements and workshops.

The purpose of this paper is to compare the performance levels of small scale local government contractors (SSLGCs) in northern part of Nigeria with international practice. Previous studies focused attention primarily on benchmarking the performance of contractors, but were mostly conceptual rather than from empirical findings. This continuous to pose a challenge to the sustainable development of the construction industry, particularly, in developing countries like Nigeria. There is therefore a need to identify, assess and compare performance practice levels of small scale contractors.

The performance of each contractor was evaluated using a five-point Likert scale used in obtaining mean performance levels in respect to three classes of performance practices. A questionnaire survey was administered to major parties in the industry; clients, contractors and consultants who were selected by using a proportionate stratified random sampling technique. The contractors’ performance was compared by using ANOVA with post hoc.

The results indicated that the SSLGCs in Nigeria were average performers and there were effects and differences among the various contractors’ levels of performance with international practice.

The study is limited to SSLGCs in northern part of Nigeria.

The study provided the criteria for evaluation of SSLGCs’ performance in Nigeria and other developing countries that faced similar problems.

The study created bases for self-evaluation and competition among small scale contractors in Nigeria for the enhancement of productivity particularly in rural areas and general national development.

This study emanated from the governmental reports and past researches in the area of performance management on the persistence of the poor performance of small scale contractors in construction industry.

Construction industry faces challenges in making objective decisions due to monetary value attached to quality. Among various quality management techniques available, cost of quality (COQ) is one such method used to address the concern. However, the absence of measurable COQ factors to monitor quality costs hampers the implementation of COQ framework in the construction industry. Therefore, this study aims to identify COQ factors focused on visible factors (VF) and hidden factors (HF) and the current requirements to achieve it.

This study is based on Preferred Reporting Items for Systematic Review and Meta-Analyses protocol guidelines. The present study identified 57 articles published between 1992 and 2023 in peer-reviewed journals.

The findings reveal 22 factors, which are grouped into four categories based on COQ. Through systematic review, the authors observed limited methodological and theoretical diversity. In fact, there are no quantitative frameworks to calculate COQ. The study, therefore, developed a framework comprising four major routes/paths of COQ factors within the framework.

The COQ routes developed through this study will enable the practitioners to meticulously categorise VF and HF, facilitating quantifying of quality throughout the lifecycle of project, which is currently absent from the existing quality assurance/quality control (QA/QC) approach. In addition, these COQ routes stand as essential construction strategies, significantly enhancing outcomes related to time, cost, quality, sustainability and fostering closer relationships within project frameworks.

The current study contributes significantly to the existing body of knowledge by developing various COQ routes and proposing future research directions to address gaps in the literature.

The purpose of this paper is to identify factors affecting cost estimate accuracy in each of five design stages preceding building construction: order of magnitude, conceptual/schematic, detailed design, construction document and bid phase.

Data were collected using an online survey completed by 138 respondents who work in design consultancy firms in Jordan, including project managers, architects and quantity surveyors (QSs). Survey responses were analyzed using descriptive statistics. Confirmatory interviews and case study comparisons were used to confirm the statistical analysis results.

The results of this study indicated that each design stage’s cost estimate was affected by several factors. Two significant factors were common across four of the five design stages: client experience and project team experience. In addition, a high level of agreement was observed among the project managers, architects and QSs regarding the factors affecting cost estimate accuracy.

Accurately estimating building construction costs during the design process has posed a challenge for designers and their clients in Jordan. Despite the care and effort involved in preparing cost estimates in each of the five design stages, deviations are commonly observed. Because the accuracy of building construction cost estimates directly affect the success or failure of a project, the results of this study can be used to reduce uncertainties in building construction cost estimation and subsequently increase the likelihood of project success
