Oman commitment for Sustainable Development Goals 2030 pushes green building at the forefront of construction industry. However, its green building progress is slower than other Gulf Cooperation Council countries, and only a handful of local contractors have been involved in green project development. Understanding the barriers to green project delivery will open avenues for better project planning and preparation. This research aims to identify the barriers experienced by the contractors when constructing green buildings in Oman.

Qualitative research, via a semi-structured interview process, explores the barriers experienced by 14 contractors when constructing Leadership in Energy and Environmental Design (LEED) green building projects in Oman. Using NVivo 12 software, thematic analysis was conducted through the generation of coding and themes which enable the identification of the relevant barriers.

The research uncovered 10 barriers and grouped them into five categories. The five categories are as follows: (1) insufficient skills development, (2) lack of government support and regulatory adjustment, (3) limitation in materials procurement, (4) documentation and coordination limitation and (5) difficulty in green rating compliance.

The research identified 10 barriers of constructing green buildings in Oman. These barriers gravitated on 4 issues: knowledge and competency, green rating requirements, government involvement and materials procurement. It streamlined clusters of the potential research area for more effective green building action plans in the future. Two barriers are deemed uniquely applied to Oman, namely “lack of needed regulatory adjustment” and “absence of local rating tools”. This insight can serve as a valuable steppingstone to push more green buildings for the country.

This study explored the ramifications of COVID-19 on construction operations in Malaysia.

Following a detailed literature review, 37 ramifications are identified and divided into nine aspects. A self-designed survey is then employed to seek the perceptions of construction practitioners around the Klang Valley region regarding the significance of the ramifications. A total of 203 valid responses are subjected to statistical analyses to prioritise the ramifications.

All the potential ramifications are perceived to be significant, with the five utmost critical ramifications being rescheduling the project timeline, compliance with government SOP, delay in the handover project, compulsory COVID-19 test for all workers and the extra cost incurred to provide COVID-19 test for workers.

This study highlights the ramifications of COVID-19 on construction operations and deliberately informs construction organizations regarding the shortcomings of recent construction management. Besides, the insights suggested that industry practitioners devise corresponding strategies for project sustainability in future similar crises.

The findings serve as a valuable reference and are benign to industry professionals and researchers from developing nations, especially nations that share similar characteristics to Malaysia.

The paper examines the influence of procurement capabilities (skills) and procurement planning on project success in Ghana. The paper further examines the mediating role of procurement planning.

Drawing insights from human capital theory, a model of four hypotheses was developed and validated. The proposed model was validated using survey data from 200 procurement and construction professionals at construction firms in Ghana. The data gathered was analysed using structural equation modelling. Confirmatory factor analysis using Amos software was conducted to establish reliability and validity of the constructs. Hayes process was employed to test the structural model.

Our study revealed that procurement capabilities and procurement planning directly improve project success in the construction sector in Ghana. We found procurement planning acts as a pathway for achieving greater success in construction projects.

This study is among the very few attempts to demonstrate how project success could be enhanced through developing procurement capabilities for effective procurement planning. Theoretically, this study is among the first attempts to theorise the effect of procurement capabilities and planning on project success from the human capital perspective. Our findings also offer practical insight to practitioners in the construction setting by emphasising the need to pay crucial attention to capabilities and planning in the quest to enhance project success in the construction setting. The findings indicate that building capabilities alone is not enough; rather, the ability to deploy such capabilities for effective procurement planning is necessary for driving project success.

The aim of this study is to investigate the influence of Project Management Office (PMO) functions on project performance in businesses in Lower Middle-Income Countries (LMIC) using Partial Least Square–Structural Equation Modelling (PLS–SEM).

Utilizing close-ended questionnaires in a cross-sectional survey, 256 project professionals from 10 business sectors in Ghana views were elicited. The questions were developed through a comprehensive literature review and involved 27 PMO functional measures grouped into 6 and 19 project performance measures grouped into 6. Data collected was then analysed using the PLS–SEM to validate the hypothetical relationship.

The PLS–SEM model supported 13 (t > 1.65) out of 36 hypotheses investigating the relationship between PMO functions and project performance. Variations in the PMO functions moderately (R2 = 0.34) explained the performance of projects. The aggregate activities of the PMO had the highest significant influence on environmental performance (R2 = 0.467). The topmost PMO function was identified as monitoring and controlling project performance, and it was significantly associated with cost (ß = 0.265, p < 0.05), quality (ß = 0.291, p < 0.05) and project scope (ß = 0.265 p < 0.05) performance.

This research has brought more illumination to the functions of PMOs and its influence on project performance. The results suggest that PMO activities, when tailored to the business context, can significantly change project performance variables.

Most research on PMO and project performance has been limited to developed countries or a single sector. This study uniquely expands the business sectors and focuses on LMICs.

Ghana’s legal framework for procurement has undergone substantial reform to increase its efficacy. However, disregard for legal obligations set forth has resulted in issues of fraud, corruption and poor oversight. This study seeks to synthesize literature on the recognition of legal obligations arising from tendering procedures and measures to promote fairness, transparency and accountability under Ghana’s procurement framework.

Legal frameworks and publications from diverse countries have been synthesized using a systematic literature review across three databases (Scopus, JSTOR and HeinOnline) to illuminate key concepts, issues and best practices relevant to the study. Data obtained from included publications was synthesized using Sandelowski and Barroso’s two-step approach by using a qualitative meta-summary and thematic synthesis.

The study reveals that issues of conflict of interest, corruption, lack of capacity, inadequate oversight and insufficient legal follow-through hinder the effectiveness of procurement regulations. The findings highlight the need for targeted improvements in resource allocation for consistent application of transparency measures, regular publication of notices and robust enforcement of accountability mechanisms. The report proposes the creation of a common data environment for networking and information dissemination, implementing feedback systems and trust rating schemes.

The study contributes to the body of knowledge on procurement regulation by providing a thorough analysis of Ghana’s procurement framework. The findings will help policymakers close the observed implementation gaps by guiding the revision of current legislation and the introduction of new regulations. Research findings can be used to guide the creation of focused training courses.

This study, one of the first of its kind in Ghana, examines the current procurement framework, including legal obligations and implementation challenges. It contributes to the body of knowledge on the subject by providing a current and fact-based analysis as well as relevant recommendations for strengthening the framework.

Evaluating project success within the construction industry presents challenges due to the unique characteristics of the sector, the complexity of projects, and the involvement of diverse stakeholders. Conducting a bibliometric analysis, this paper aims to unravel the major research themes and methodologies utilised by researchers in studying the critical success criteria for construction projects, as well as extracting these success criteria.

The researchers systematically searched and screened 95 papers from Scopus and Web of Science (WoS) databases. This study conducted research focus parallelship network (RFPN) analysis and keywords co-occurrence network (KCON) analysis using BibExcel and Gephi to cluster the papers, illuminate the relationships among keywords within each cluster, and identify the primary research directions.

Using the RFPN analysis, this study classified the papers into three distinct clusters: infrastructure and public projects success, risk and knowledge management, and contractors and procurement management. Statistical techniques such as structural equation modelling (SEM) and multi-criteria decision-making methods such as analytic hierarchy process (AHP) have been used to analyse project success in the construction industry.

Considering the intensified demand for streamlined digital interactions and the increasing emphasis on sustainability and safety performance, construction companies are recommended to allocate greater investments toward the automation and digitisation of their products and processes. Prioritising modular construction and embracing transformative technologies alongside data science is crucial for enabling well-informed decision-making, and enhancing project success.

This study contributes to the existing body of knowledge by conducting a quantitative and systematic evaluation of the literature on project success criteria in the construction industry and uncovering key research areas. It addresses the pressing need to understand the complexities of construction projects amidst evolving industry dynamics and emerging disruptions. Moreover, by highlighting the implications of digital innovations and modular construction, this study urges deeper exploration into their impact on project performance and stakeholder satisfaction. This research sets a comprehensive framework for investigating the interplay between project complexity, technological advancements, and sustainable practices in the construction sector, paving the way for strategic advancements in the field.

This paper investigates the impact of green construction procurement practices (GCPPs) on circular economy (CE) success by identifying environmentally sustainable procurement practices that can promote a CE in the construction industry. The goal was to promote circularity in construction through GCPPs.

A quantitative research approach was adopted and purposively selected 100 respondents for a cross-sectional questionnaire survey. Data from the questionnaire survey were analysed using mean score ranking, One-sample t-test and regression analysis.

The study found that using on-site systematic waste management, project stakeholder commitment and support for green practices and environmental requirements in technical specifications, significantly impact CE success in construction, with a 12.8% variance in CE when green procurement is practised. This implies that GCPPs have positive repercussions on CE success, where the CE success is expected to change as GCPPs levels increase.

The study provides insights into green procurement, promoting its use in infrastructure development and aiding clients, particularly in the government sector with insights into the challenges and practices involved in green procurement. Practitioners can also benefit from better implementing CE strategies to draft and manage contracts for infrastructure projects that prioritize circularity.

The limited impact of GCPPs on advancing CE principles in construction suggests policy and practice must strengthen procurement requirements to fully leverage spending and drive the sector’s transition towards a circular model. Also, novel insight is provided into the most effective types of GCPPs for promoting CE success, aiding policymakers in optimizing construction procurement strategies.
