It is important to recruit site supervisors with the right attributes as they play an important role in raising construction productivity and improving project outcomes. The purpose of this paper is to investigate the association between a site supervisor’s attributes and project outcomes. The specific objectives are to: identify the attributes of site supervisors that are significantly correlated with project outcomes (cost, time, quality and client satisfaction); examine whether site supervisors with different educational levels and job experience have different attributes; and recommend the attributes to be considered when selecting site supervisors.

A questionnaire was designed based on the attributes identified from the literature review. The sampling frame was Singapore-based construction site supervisors. The data collected were analysed using the Statistical Package for the Social Sciences software.

The results show that site supervisors who have IT skills are also likely to have projects that have good time, quality and satisfaction outcomes. In addition, the projects of supervisors with longer work experience show significantly better time performance and higher client satisfaction.

The limitations include low response rate, and the subjective nature of a Likert scale which was used to rate the attributes of site supervisors. While the importance of hard and soft skills is known, the contribution to knowledge is that this study showed the important role that educational qualifications play in site supervisors’ performance and their soft skills.

It is recommended that contractors employ site supervisors who have at least a construction diploma, have IT skills and possess job experience in order to optimise their project outcomes.

The study revealed that certain demographic characteristics of site supervisors (i.e. length of work experience and educational qualifications) have significant impact on project outcomes. Site supervisors with higher educational qualifications and more job experience also have better soft skills.

The purpose of this paper is to investigate relational practices that can improve construction project outcomes in Malaysia.

Based on the literature review, a questionnaire was designed containing 14 relational practices that were identified and grouped under five relational norms. Using a survey questionnaire, data were collected from clients, consultants and contractors in Malaysia’s construction industry. In-depth interviews were conducted to validate the statistical findings.

When contracts are adjustable to address uncertainties, the projects concerned have better cost and quality outcomes. A better schedule outcome is correlated with coordinating and monitoring plans jointly. Open communication and sharing trustworthy project information have been found to produce better client-consultant and consultant-contractor relationships at the end of a project. When parties maintain a social relationship outside of a project, relationships between clients, contractors and consultants also improve significantly.

The findings are not easily generalisable due to the relatively small sample size, low response rate and the data being collected from only three regions in Malaysia.

Clients need to take the lead in adopting relational practices, as these may give rise to warmer relationships and better project outcomes. Showing too much commitment and flexibility may harm the project schedule because of the frequent changes.

This study found that the theory of relational contracting norms applies to Malaysia’s construction industry. The parties do not rely strictly on contract conditions but embrace role integrity, preserve relations and harmony to avoid relational conflict, and achieve their goals through proper means.

The purpose of this paper is to introduce and discuss a process for specifying project scope and success criteria more completely – in terms of expected project outcomes, benefits and outputs.

The paper reports on the third in a series of five action research case studies along with a validation exercise conducted at an Australian state police force senior management conference.

The findings confirmed that project stakeholders are able to identify, prioritise and define intangible project outcomes when provided with a process for doing so. The process described in this paper provides project stakeholders with the means to cross‐reference hitherto inexplicit intangible outcomes to explicit tangible outputs. Results indicate strong support for the process as a planning/review tool for projects required to deliver a combination of tangible and intangible outcomes.

The series of five action research case studies was drawn from the public sector. Nevertheless, the authors propose that the approach can be applied more generally to projects which require the delivery of intangible project outcomes. The validation exercise conducted at an Australian state police force senior management conference collected workshop attendees' responses to brief pre‐ and post‐workshop surveys. Whilst encouraging, the results should be treated with caution because survey responses were only collected from people responsible for delivering project outcomes, not receiving them.

The key breakthrough contribution of the process described in this paper is the use of outcome profiles to cross‐reference intangible outcomes to tangible outputs; making the intangible tangible.

Earned value management systems (EVMS), also called integrated project and program management systems, have been greatly examined in the literature, which has typically focused on their technical aspects rather than social. This study aims to hypothesize that improving both the technical maturity of EVMS and the social environment elements of EVMS applications together will significantly impact project performance outcomes. For the first time, empirical evidence supports a strong relationship between EVMS maturity and environment.

Data was collected from 35 projects through four workshops, attended by 31 industry practitioners with an average of 19 years of EVMS experience. These experts, representing 23 organizations, provided over 2,800 data points on sociotechnical integration and performance outcomes, covering projects totaling $21.8 billion. Statistical analyses were performed to derive findings on the impact of technical maturity and social environment on project success.

The results show statistically significant differences in cost growth, compliance, meeting project objectives and business drivers and customer satisfaction, between projects with high EVMS maturity and environment and projects with poor EVMS maturity and environment. Moreover, the technical and social dimensions were found to be significantly correlated.

Key contributions include a novel and tested performance-driven framework to support integrated project management using EVMS. The adoption of this detailed assessment framework by government and industry is driving a paradigm shift in project management of some of the largest and most complex projects in the U.S.; specifically transitioning from a project assessment based upon a binary approach for EVMS technical maturity (i.e. compliant/noncompliant to standards) to a wide-ranging scale (i.e. 0–1,000) across two dimensions.

The purpose of this paper is to examine the major management issues that impact on mega transportation infrastructure projects in the United Arab Emirates (UAE) and identify the factors that cause unsuccessful project completions. The paper further seeks to identify the changes that can be made to improve project success.

This is a qualitative study that involved face‐to‐face interviews with 20 key experienced transportation construction stakeholders who had been involved in a number of different projects in the UAE. This was followed by a focus group discussion involving ten key stakeholders who had been involved in the construction of a mega project – the Dubai Fujairah Highway. Analysis of the interview data was conducted using NVivo.

The findings highlight the complexity involved in managing mega transportation infrastructure projects in the UAE. Multiple stakeholders (government agencies, sponsors/clients, management firms, consultants and contractors) influence the various stages of projects. The need for effective communication, coordination, knowledge sharing and decision making amongst the stakeholders, especially during the planning and design stages, is highlighted as critical.

The main limitation is the small numbers interviewed for each stakeholder group. Nevertheless, the sample of interviews provides a good representation of the transport infrastructure construction industry in the UAE.

Three major practical implications relate to: improving communication and coordination amongst government departments and key stakeholders to streamline effective knowledge sharing and decision making, leading to successful project outcomes; improving the skills and competencies of professional staff at all levels and subsequently delegating authority to lower levels; and the adoption of global international standards to improve planning, design and construction activities.

The paper describes the first study of its kind conducted in the UAE that provides valuable insights with respect to transportation infrastructure project management.

The purpose of this study is to investigate the relationship between sustainable leadership and sustainable project performance. Specifically, the study aims to examine the mediating role of knowledge integration, examining how knowledge integration within an organization influences project outcomes. In addition, the study seeks to explore the moderating role of top management knowledge values, examining how the values and beliefs of top management influence the relationship between sustainable leadership and project performance.

A three-wave survey of 392 employees working in construction sector projects in Pakistan used both hierarchical regression analysis and Hayes’ PROCESS macro method to evaluate the hypotheses.

The study results show that sustainable leadership positively relates to sustainable project performance and knowledge integration mediating this relationship. In addition, the top management knowledge value moderates the indirect effect of sustainable leadership on sustainable project performance via knowledge integration.

Although the model was tested using three-wave data, it is important to note that the data were obtained from a single source. Therefore, it is possible that common method bias may have influenced the results, and this cannot be disregarded.

Organizations seek to prioritize sustainability and integrate sustainability considerations into their project management processes. Organizations can achieve improved sustainable project performance by investing in sustainable leadership development, fostering a culture of knowledge sharing and learning, prioritizing top management support for sustainable performance and integrating sustainable considerations into project management processes.

The study’s grounding on organizational learning theory adds an original and valuable perspective to the relationship between sustainable leadership and sustainable project performance. This investigation is original, as it combines sustainable leadership, knowledge integration and the moderating role of top management knowledge value to understand their impact on sustainable project performance. This unique approach contributes to the literature by providing new insights into these relationships and mechanisms in the construction industry.

The purpose of this paper is to report on research which has developed a new approach to capturing project‐based learning.

Action research was employed as part of a longitudinal single organization case study.

Project learning processes can be improved by using an event‐based approach to project knowledge integration that propagates duetero‐learning. The approach developed generates outputs that codify lessons learnt and promotes measurement of benefits. The event and the outputs, in effect, take the form of “boundary objects” which act as a bridge or means of translation between the participants, as well as to those who will use the learning to improve their own project practice on other projects.

The approach has only been applied within a single support services organization, but could provide a way of overcoming the considerable difficulties inherent in capturing lessons learned within project‐based environments.

The approach helps to overcome the key issues of obtaining management and staff buy‐in, and dealing with the time pressures that exist in project‐based environments. The outputs can be applied to encourage learning across projects and wider communities resulting in improved practice.

The process uses the concept of boundary objects to explain how some of the problems arising when complex abstract concepts are involved can be overcome, particularly in increasing understanding and buy‐in from the actors involved. Viewing learning events as boundary objects sees them as mediating information across project boundaries, between project practitioners and across business units. The event process can be adapted for a variety of scenarios and used by an organization or group of organizations to improve and apply learning more successfully.

The purpose of this paper is to identify control systems that give rise to better construction project performance; and develop and test project performance predictive models based on control systems adopted in the project.

Research design was questionnaire survey. Data were collected via Electronic mails. The sampling frame was Singapore-based construction firms.

In all, 16 control mechanisms are significantly correlated with project outcomes. The more important control mechanisms are: adequacy of project information to develop the project schedule; adequacy of float in the schedule; and quality of techniques used to support risk identification. Two relatively robust predictive models were constructed and validated to predict schedule and quality outcomes of construction projects. Schedule performance may be predicted by adequacy of float and stringency of criteria to select suppliers. Quality outcome is most significantly affected by competency of quality manager, rather than the hard systems adopted in the project.

The limitations include low response rate, and subjective nature of the five-point Likert scale used to rate project outcomes and extent to which control mechanisms were adopted in the project.

The implication of the findings is that merely having good project management practices and adequate resources are not sufficient to achieve good project outcomes. Instead, construction projects need to have control systems in place, as they play an important role in project outcomes.

The paper has shown empirically that control systems affect project outcomes. They are needed not just to control the project, but also help the project to achieve good outcomes. The research designed and tested two relatively robust models to predict schedule and quality outcomes of a project. These models may be used to make an initial assessment of the project's likely outcome, based on the control systems that contractors are going to adopt.

Communication plays an important role in the quality of the relationship, trust and collaboration among construction project teams. Literature suggests that effective communication is vital for achieving improved project performance. The purpose of this paper is to identify and assess the barriers to effective communication in the Nigerian construction industry, using attribution theory paradigm.

Questionnaires detailing 15 barriers to effective communication were administered to consultants and contractors engaged in the Nigerian construction sector. In total, 100 valid responses were analysed using mean score, factor analysis and factor score.

Unclear project objectives, ineffective reporting systems and poor leadership were ranked as the most significant barriers to effective communication. Factor analysis uncovered that the principal reasons responsible for ineffective communication include: managerial and technical barriers and credibility and background barriers.

The results provide information on barriers which needs to be addressed in order to improve communication in construction projects in Nigeria. There is a need to conduct post-completion reviews of construction projects so that project team members can learn and share knowledge on past experiences. Although the present study was conducted in the Nigerian context, it is envisaged that the research outcome will be widely applicable to other developing countries.

The study provides insights on the perceived barriers to effective communication in Nigerian construction projects. The paper presents the direction for further research aimed at improving communication in construction projects in Nigeria.

Perceived benefits of building information modelling (BIM) have been discussed for some time, but cost–benefit benchmarking has been inconsistent. The purpose of this paper is to investigate BIM feasibility and evaluate investment worth to elucidate and develop the current understanding of BIM merit. The aim of the study is to propose a research agenda towards a more holistic perspective of BIM use incorporating quantifying investment return.

An in-depth examination of research patterns has been conducted to identify challenges in the assessment of the investment value and return on investment (ROI) for BIM in the construction industry. A total of 75 research articles were considered for the final literature review. An evaluation of the literature is conducted using a combination of bibliometric analysis and systematic reviews.

This study, which analysed 75 articles, unveils key findings in quantifying BIM benefits, primarily through ROI calculation. Two major research gaps are identified: the absence of a standardized BIM ROI method and insufficient exploration of intangible benefits. Research focus varies across phases, emphasizing design and construction integration and exploring post-construction phases. The study categorizes quantifiable factors, including productivity, changes and rework reduction, requests for information reduction, schedule efficiency, safety, environmental sustainability and operations and facility management. These findings offer vital insights for researchers and practitioners, enhancing understanding of ’BIM’s financial benefits and signalling areas for further exploration in construction.

The ’study’s outcomes offer the latest insights for researchers and practitioners to create effective approaches for quantifying ’BIM’s financial benefits. Additionally, the proposed research agenda aims to improve the current limited understanding of BIM feasibility and investment worth evaluation. Results of the study could assist practitioners in overcoming limitations associated with BIM investment and economic evaluations in the construction industry.
