Cost overrun is a significant issue in construction, an undesirable feature the industry has long been associated with. Poor procurement practices are often blamed for subsequent cost overruns in construction, especially with conventional procurement methods leading to outrageous cost overruns. The purpose of this study is to review the features of the new models of construction procurement (NMCP) and assess their potential to reduce cost overruns in construction projects.

A literature review was conducted to identify the issues of procurement leading to cost escalations. Primary data were obtained through exploratory, semi-structured interviews using a case study approach.

Clients’ lack of knowledge was highlighted as a key issue in procurement that interlinks with many factors causing cost escalation. The findings suggest that the features contained within the NMCP, such as early contractor involvement and collaboration throughout the project team, have the potential to make a positive contribution to addressing cost escalation in construction.

The primary research was undertaken as an exploratory study and presents the contractor's perspective. Further research is therefore suggested, with multiple organisations representing all key stakeholders in a construction project, including clients, consultants, sub-contractors and suppliers.

The study recommends awareness of the NMCP be raised throughout the industry, and simplified information must be made available to help widen uptake of these contemporary procurement methods.

Addressing the dearth of research concerning the use of NMCP within the industry, this study makes a niche contribution to the body of knowledge on construction cost management by illustrating the potential offered by these new procurement methods for addressing cost escalation. For an industry where collaboration is accepted with reservations, this case study demonstrates how novel collaborative strategies such as open book costing, project bank accounts and shared pain and gain mechanisms can be implemented as part of the procurement strategy and how such strategies can contribute towards minimising the cost escalation inherent in construction projects.

Offsite construction (OC) is an efficient method to reduce waste in the construction industry from a circular economy perspective. Yet, its uptake is subdued by the ambiguities around its supply chain. Hence, the purpose of this study is twofold: to identify the OC project delivery models, the limitations in their procurement approach to facilitate the resilience of the supply chain and interventions to promote supply chain resilience (SCR) and to identify the gaps in the existing procurement process and propose further research areas that implement strategies to improve SCR.

The study was conducted as a systematic literature review. In total, 41 peer-reviewed research papers published between 2013 and 2023 were shortlisted through the preferred reporting items for systematic reviews and meta-analysis guidelines. A descriptive analysis was conducted, followed by a thematic analysis.

The descriptive analysis reveals that the emphasis on digitising OC has shifted to transforming the business model, procurement and supply chain with a human-centric view. In thematic analysis, the predictability of the SC partners and the probabilities of evaluating the prospects are revealed as arbitrary characteristics in the current procurement strategies. Rewarding collaborative relationships among SC partners and incorporating provisions to postpone the module delivery are some interventions to promote flexibility. Drafting comprehensive and effective contracts that address transparency issues and facilitating the need for continuous development of capabilities through procurement are among the further research avenues proposed.

This study is a precursor demonstrating the potential of the procurement process to implement the decrees of SCR for better goal congruence of the OC supply chain.

The purpose of this study is to investigate the influences of the characteristics of procurement strategies, in this instance labour-only, on project performance concerning health and safety (H&S), a project performance indicator.

Using non-probability purposeful and snowballing sampling methods, questionnaires were used to collect data from construction professionals in Nigeria. This was then analysed using descriptive (frequency and mean scores) and inferential statistics (Mann–Whitney-U and Kendall's Tau_b tests).

The findings indicate a statistically significant negative correlation between ‘the level of client involvement and ‘fatalities' and a positive one with ‘conducting of health and safety risk assessment' and ‘conducting employee surveys on health and safety attitude’. Poor hygiene is found to be the worst lagging indicator, while conducting of inspection is the most adopted leading indicator of project health and safety performance. It also emerged that there is no significant difference in the health and safety performance of projects procured through the procurement strategy in urban and rural areas.

The study provides valuable insight into the complexities in H&S management due to the high level of client involvement in labour-only procurement system (LoPS) projects and the level of diversity in their responsibilities therein. It creates a fundamental direction for developing a detailed framework or guidance notes for client involvement in the integration of H&S into LoPS projects.

This is the first study that examines the influence of the characteristics of procurement strategy on project health and safety performance. Evidence in the literature shows that project delivery outcomes significantly improve if procurement is strategically used, including when it is considered early in projects. However, integrating H&S into procurement strategies has received little attention.

This study aims to explore the experiences of using competitive dialogue (CD) as a procurement procedure and the freedom it provides to the contracting parties in Norway.

This study opted for qualitative research design. Data were collected from four case projects through document reviews and in-depth interviews with procurement experts and key contract partners of the projects.

Results indicate that CD has some room for maneuver that is worth trying. Furthermore, the research identified several measures that can be implemented to use the procedure effectively. Contracting parties that have used the procedure have had various positive experiences.

The findings have implications in improving project outputs, building better trust and cooperation between the contracting parties and better use of public money on projects that have lasting outcomes for the society.

The authors studied four actual projects that used CD as a procurement procedure and aimed to provide first-hand information on the degree of freedom that it offered to the contracting parties.

International development projects are a dominant means by which aid is distributed to countries. Over the past 70 years, the distribution of trillions of dollars of development aid has been mediated by the United Nations (UN). However, most of this aid has failed to deliver the expected outcomes for which it was assigned. Nevertheless, a significant proportion of projects can be considered successful. Despite the glaring question as to which factors contribute to the success or failure of projects, no study has comprehensively documented the relationship between procurement mechanisms invoked to deliver aid projects and project outcomes. This study aims to assess this relationship.

Leveraging network analysis methodology, this study examines the World Bank data set of over 247,000 developmental contracts worldwide granted over the past 20 years. It identifies the range of procurement practices used and interrogates their ability to deliver satisfactory project outcomes.

Eleven prevalent practices are identified covering aid projects across twelve sectors. As might be expected, Africa is the largest recipient of aid, while the Middle East is the least. Overwhelmingly, international competitive bidding (ICB) is the leading procurement procedure, both in terms of contract number and total dollar value. However, ICB does not always deliver the best outcomes, with other, more boutique approaches sometimes doing better.

The breadth of this study, encompassing such a vast data resource, and generating such a rich pool of findings will now empower researchers to take the next important step, which is to progress this study in exploring why it is that certain procurement strategies have worked for some sectors, but not others. Countries, financial institutions, the UN and construction enterprises alike will be very interested in the results.

The spectrum of outcomes identified will be of interest to academics and practitioners alike wishing to investigate further the drivers behind the results described here.

The purpose of this study is to investigate the benefits and challenges of implementing circular economy (CE), as well as shed light on the influence of procurement strategy in CE implementation in construction projects.

A qualitative research approach with abductive reasoning was adopted. The empirical data were collected from the construction industry in the United Arab Emirates (UAE).

The results reveal that clients, consultants and contractors have limited awareness, knowledge and motivation to implement CE in construction projects. The absence of incentives to design projects following CE principles, lack of involvement of contractors and suppliers, non-use of materials that use CE principles and current procurement strategies are the main challenges for the implementation of CE in the UAE.

Previous research offers limited knowledge on CE and its implementation in construction projects particularly from a procurement strategy perspective. The findings of the study provide new knowledge of the benefits, challenges and role of procurement strategy for implementing CE. It is suggested that collaborative and partnering-based procurement methods are needed to facilitate the effective implementation of CE.

Pre-construction of a project comprises stages that are pivotal for the procurement performance. It is defined as the duration from the project's initiation to construction. However, Private Public Partnerships (PPPs) have been subjected to a long pre-construction, thereby leading to an inefficient development process. Therefore, the purpose of this paper is to pay attention to the influencing factors elongating the pre-construction duration.

Based on data of 5,677 PPP projects between 2009 and 2021 in China, the authors adopt the Accelerated Failure Time (AFT) model in duration analysis to empirically analyze the following underlying dynamics determining the duration of PPP pre-construction stages: (1) policy uncertainty; (2) corruption; and (3) procurement method selection. To observe the influencing paths more specifically, the authors divided the pre-construction duration into the pre-tendering period and tendering period and regressed them separately.

The results indicate that the pre-construction duration is significantly prolonged with increased policy uncertainty and corruption degree as well as the use of tendering methods. Meanwhile, the above factors have a greater impact on the pre-tendering period than the tendering period.

The contribution of this study is twofold: (1) theoretically, this paper provides new evidence on the impact of PPP policy uncertainty, corruption and procurement method selection on the pre-construction duration. It complements empirical studies on the factors elongating the time efficiency of PPPs projects. (2) In practice, it provides a specific path for the government to improve the time efficiency of PPPs.

Previous studies have established to a great extent that regulatory frameworks and, in particular, procurement approaches – that are common in a particular context – have a major impact on the success of building information modelling (BIM) implementation in construction projects. Despite the close links between these two concepts, research on the effect of procurement approaches on BIM implementation is scarce. To address this gap, this paper aims to investigate the barriers that affect BIM implementation through the lens of procurement approaches.

A mixed-method approach was adopted using a questionnaire survey (n = 116) and interviews with key stakeholders (n = 12) in Jordan. The outcomes of the quantitative parts were augmented with findings from interviews.

It was revealed that the deployment of unfavourable construction procurement approaches represents a major hurdle towards BIM implementation. Though essential for enhancing BIM implementation, it is revealed that a fundamental change from the common design-bid-build (DBB) to more collaborative procurement approaches remains infeasible in view of the realities that govern the construction industry.

It was revealed the deployment of unfavourable construction procurement approaches represents a major hurdle towards BIM implementation. Though essential for enhancing BIM implementation, it is revealed that a fundamental change from the common DBB to more collaborative procurement approaches remains infeasible given the realities that govern the construction industry.

As the first of its kind, a set of recommendations for establishing supportive, workable procurement that does not deviate significantly from common procedures and practices is presented. Rather than advocating a shift to procurement approaches that are aligned with BIM, the findings offer novel insight into the necessity of developing a framework within the boundaries of the current and widely adopted procurement approaches to address the identified construction procurement issues and facilitate BIM implementation.

Construction frameworks are recognised by the UK Government as an integrated procurement path to deliver efficiency, collaboration and sustainability. This research paper aims to develop a performance-driving model for framework procurement to align with the government construction policy objectives.

A quantitative hierarchical regression analysis was conducted to examine the causal relationships between project outcomes and performance drivers. A successive qualitative multiple-case study involving eight typical construction framework projects was examined to further explain casual relationships.

Conclusive results from the quantitative and qualitative analyses validated the performance-driving model, generalising a framework procurement principle that project outcomes of time, cost, quality, sustainability and closer relationships are significantly driven by supplier's task and contextual performance drivers, and client's organisational drivers.

The investigation followed two major public-sector organisations in the UK: infrastructure offices of local authorities and estate offices of universities. Further research should be extended to other public-sector situations to enhance the model further.

Using this model, framework managers can drive project outcomes by applying task and contextual performance drivers in order to select the best suppliers at the procurement phase, and by adopting the client's organisational factors at both procurement and construction monitoring phases.

The empirical evidence supports the use of frameworks by public sector policymakers as a key strategy to develop the performance drivers further and improve efficiency and quality outcomes.

The results will be of value to support the policy of public-sector works organisations contemplating using framework procurement for executing continuing construction activities.

Effective procurement of infrastructure is partly dependent on infrastructure procurement personnel having the skills that are important for the discharge of their role. Addressing the infrastructure deficits in developing countries, therefore, calls for an understanding of the skills that are important for the discharge of the roles of public personnel that are involved in infrastructure procurement. This study aims to investigate these skills from the perspective of public infrastructure procurement personnel in the sub-Saharan African region.

A questionnaire survey of procurement personnel yielded 590 useable responses, which were analysed using t-tests and exploratory factor analysis (EFA).

EFA established eight key components of important infrastructure procurement skills to include skills related to: project success factors; social and environmental sustainability; marketing and e-procurement; project phase management, the application of procurement laws and procedures; soft skills, ICT and communication; and data analysis and team building.

The findings are crucial in developing infrastructure procurement capacity building programmes that would be appropriate for infrastructure procurement personnel in developing country contexts. Infrastructure procurement personnel ought to engage more in capacity development training that is aligned to enhancing skills within the eight components.
