Although several digital tools and technologies (DTT) have been employed in MiC projects, no previous research study has critically reviewed and analysed their implementation in MiC projects. The current study addresses this gap using a three-tier research approachβ data curation, science mapping, and systematic analysis to evaluate modular construction research studies. The findings revealed minimal application of DTT in the MiC prefab transportation phase and the potentiality of blockchain and other integrated DTT for use in MiC projects. Globally, Canada, China, and the USA are the leading countries that have applied DTT in MiC projects. Also, simulation, building information modelling (BIM), and optimization algorithms are the most frequently deployed DTT in modular construction. This study has provided valuable insights into the digital technologies adopted in MiC projects and potential areas for its future use in modular construction.

SSP is coined from the integration of digital technologies such as Building Information Modelling (BIM) to facilitate sustainability practices.
Design/methodology/approach β The study employed a quantitative research design approach using empirical questionnaire surveys to solicit the opinions of 69 and 97 construction practitioners in Nigeria and Hong Kong. Purposive and snowball sampling techniques were used to identify the potential survey respondents. The fuzzy synthetic evaluation technique was used to develop the PEMs.
Findings β The findings revealed that adequate technical expertise of the SSP processes is critical in enhancing its implementation in Hong Kong and Nigeria; as well as the provision of training programs for specialists in smart and sustainable initiatives. Meanwhile, the studyβs findings advocated that for an SSP- enabled construction project, its project performance is mainly influenced by the clientβs satisfaction level and the early involvement of the project teams.
Research limitations/implications β The studyβs results are limited to the Nigeria and Hong Kong construction industries.
Practical implications β Construction stakeholders such as the clients, developers, contractors can utilize the PEMs to determine and track SSP initiatives implementation in building projects in a reliable and practical way.
Originality/value β No tool has been developed for evaluating SSP initiatives at the project level in the construction industry. Using case studies of Hong Kong and Nigeria, PEM indices were developed to measure and track SSP implementation in construction projects.

However, the extant literature revealed salient gaps in the use of cloud-based systems and digital tools to evaluate buildingsβ sustainability performance. Consequently, the current study aims to develop and implement a cloud-based sustainability assessment (CSA) system to evaluate and compare the sustainability performance of buildings based on the Building Sustainability Assessment Method (BSAM) scheme green rating system. A design science research (DSR) approach was adopted in designing, developing, and validating the CSA system. The developed CSA system is based on the SaaS model of cloud computing. The methods evaluation validation of the CSA system when compared with other systems revealed that the developed CSA system would result in higher time and learning efficiency for the users. The findings from the case study validation of the CSA system, using four building projects, indicate that the developed artefact offers a better secured, automated, reliable, and value-adding tool for the building sustainability assessment process. It also eases the automated process of updating data, evaluating, and comparing building projects towards improving the overall building sustainability profile. More so, the CSA system has a great potential to assist stakeholders in their buildingsβ sustainability decision-making process and enhancing sustainable development.

The statistical population included active experts in the field of construction in the study area. The sample size was determined using the Cochrane formula, and purposive and convenience sampling was used to select 118 participants as the primary sample. The questionnaire used in this study was based on 63 CSFs items derived from the extant literature, which were categorised into eight CSFs categories. The findings indicated that the mean rank score of the CSFs for managing construction SMEs for the CSFs categories and each CSFs item ranged between medium and high, and all CSFs items and areas can be considered significant CSFs for managing construction SMEs in developing countries of the Middle East. Furthermore, in the ranking of the CSFs categories, technology with an average (MS) of 6.38 was rated the most significant CSFs category, followed by human resource management aspect (MSβ―=β―5.48), dynamic capabilities (MSβ―=β―5.30), and organisational management (MSβ―=β―4.76). It is expected that the study findings and recommendations would significantly contribute to improving project success and efficiency of construction SMEs in developing countries while deepening stakeholdersβ awareness of critical variables for prioritisation in order to remain competitive in the construction industry.

Content analysis, a two-round Delphi survey technique, and a series of validation and reliability tests helped establish the 18 key criteria for FAHP analysis. Consequently, data collected from experts through a pairwise comparison questionnaire form the basis for the inputs for the FAHP analysis. Consequently, the final weightings were derived for each of the key criteria and available contracting methods. The results indicate that the bilateral, cooperative, and trilateral contracting methods are the most suitable for WWP in Iran, with the highest weighting. The study provides useful guidance for the top management of project firms in selecting the optimal contracting method for their projects and offers significant contributions from theoretical and practical perspectives.

The study employed a conceptual framework design, expert surveys, and case studies to identify and establish the different components of the GBA framework. The developed GBA framework incorporates the BSAM scheme as its primary green building rating system and provides a cost-effective solution for sustainability appraisal. The findings revealed that the 4Ws of the information exchange workflows would facilitate the GBA systemβs implementation and the expert validation confirmed its suitability for the Nigerian context. The C-SDSS served as the digital component of the GBA system towards automating the sustainability performance assessment of buildings. The GBA system provides the construction industry with a useful tool that could ease comparing two or more building projects or its designs for several uses β such as contract bidding, evaluating alternative designs, and the like. The application of the GBA system can be extended to facilitate its adoption in other regions or countries. The studyβs deliverables are expected to enhance smart and eco- initiatives in Nigeria and sub-Saharan Africa.

Hence, the current study aims to investigate the key delay factors and provides salient recommendations. In this study, multi-criteria deci- sion-making β the Analytic Network Process (ANP) and the DEMATEL (Decision Making trial and evalu- ation laboratory) method was employed to help decision-makers in prioritizing these delay factors and evaluating their interactions, respectively. A Delphi approach was used to validate the studyβs findings via expert questionnaire surveys β based on a rail transportation development project for the Mobarakeh Steel Complex (MSC). The studyβs findings revealed the management factors as the most important delay factors, followed closely by the financial, design, and implementation factors. Other potent issues include the existence of numerous decision-making stations, lack of central role, and sufficient authority for the project managers are responsible for project delays. Overall, the results show that resolving problems with the βmanagementβ domain can significantly avoid or alleviate the extent of delays in rail transporta- tion development projects. The studyβs findings and recommendations can serve as a policy and consulta- tive instrument for the relevant stakeholders in the railway industry.

The consideration of the regional context in the development of green building rating systems is ... more The consideration of the regional context in the development of green building rating systems is well established in the extant literature, and this informs the development of a sustainability assessment method for sub-Saharan Africa. Hence, a multi-expert consultation method was carried out in Nigeria which is the largest economy in the region. This was performed via a structured questionnaire survey and interview approaches to identify the key sustainability assessment criteria, assign score-weights to the various criteria, and establish the certification grading system of buildings. The developed Building Sustainability Assessment Method (BSAM) scheme and its weighted criteria were validated using two existing building case studies. The established BSAM scheme was compared to six widely used green building rating systems. The comparative analysis reveals that the score-weights and priorities of the BSAM scheme were remarkably different from the existing rating systems. The study findings also show the increasing focus on the indoor environmental quality and energy criteria by all the rating systems. The developed BSAM scheme, meanwhile, has adequately considered the three main pillars of sustainable development unlike the existing green rating tools. Hence, it is expected for the proposed BSAM scheme to promote greener buildings and enhance sustainable urban development in the region.

Using the BSAM scheme β a green building rating system developed specifically for the sub-Saharan region of Africa, the generalized Choquet fuzzy integral method was employed to determine the importance weights of the sustainability assessment criteria. Data collected from industry experts form the base inputs for the impact of the various sustainability criteria based on the local variations. Consequently, the building sustainability evaluation index and grading scheme were developed to measure and evaluate the sustainability performance of buildings. The developed sustainability rating model was validated in four real-world case studies to demonstrate its usefulness and robustness in practice. The findings revealed that the conventional approach of aggregation of points used by the existing green rating tools is less effective in dealing with criteria that have interactive characteristics. Also, assessment criteria such as sustainable construction practices, transportation, and energy have a significant impact on the sustainability of buildings. The study provides substantial contributions to the existing body of knowledge about green building assessment systems for built environment stakeholders, both from the theoretical and practical perspectives.

The current research study aims to identify and assess the perceived benefits of and barriers to BIM implementation in the Hong Kong construction industry. The study adopted a quantitative research design using a structured empirical questionnaire survey. Also, a comparative analysis of the perceptions of the respondents' groupings was conducted. The major barriers to BIM adoption are related to the inherent resistance to change by construction stakeholders, inadequate organizational support and structure to execute BIM, and lack of BIM industry standards in Hong Kong. Meanwhile, the key benefits include better cost estimation and control, efficient construction planning and management, and improvement in design and project quality. Practical and insightful recommendations were suggested for policymakers, local authorities, construction firms, and other key stakeholders to increase the uptake of BIM in construction projects as well as to aid them in the quest for full adoption of BIM in the built environment. The practical implications of the research findings were also presented and discussed.

Design/methodology/approach β The research design adopted a qualitative approach which includes the desktop review of the extant literature as well as case study reviews of ten BIM projects using an explanatory case study technique to form the foundation upon which the study proposed the model. The moving basis heuristics technique was adopted to develop the scoring system.
Findings β The BIM benchmarking model and assessment template were developed which consisted of three-level concepts modeled to aid project organizations and project team in developing countries to assess and score the level of improvement and implementation of BIM in a project. A desktop review of BIM projects in developed countries demonstrated the significant improvements and benefits possible through the implementation of the established BIM benchmarking model.
Practical implications β The assessment template in conjunction with the benchmarking model is useful for a comparative evaluation of similar BIM projects and benchmarking purposes. The study also discussed how current findings extends and contradicts previous findings.
Originality/value β The findings have provided policymakers, construction stakeholders and professional bodies in the construction industry in developing countries with valuable insights and counter-intuitive perspective that could facilitate the uptake of BIM in construction projects.

Design/methodology/approach β This involves administering a questionnaire survey to registered members of the Nigerian Institute of Quantity Surveyors, the only recognized professional body of quantity surveyors in Nigeria, within Lagos state. The empirical questionnaire survey succeeds a literature review that isolates the key strategies used by quantity surveyors in material management and waste minimization at the post-contract stage. The validity of the questionnaire was carried out by two experienced construction industry researchers and three experienced professional quantity surveyors to ensure that the questionnaire was not ambiguous and that it consists of the right questions in tandem with the research. The respondents were grouped into consultantβs QS and contractorβs QS.
Findings β Key roles of quantity surveyors during the material management process are proper material storage, and material inventory and accounting are the most important material management and waste minimization practices during the institute stage. It revealed that there is a lack of material waste documentation practices during the construction stage. In addition, there is no statistically significant difference in the responses of the two groups. This may be because there is no clear compartmentalization between the practices of the two groups. In addition, these two groups had the same education training, as there is no difference between the educational training of the consultantβs QS and contractorβs QS.
Originality/value β This study assessed the quantity surveyorsβ roles with regard to material management and waste minimization. It would add to the scanty research work in this area. The study has also successfully revealed the strategies that are to be adopted by the quantity surveyors to achieve value for money during the post-contract stage.

An explanatory case study technique and case study evidence from four BIM construction projects form the study's research design. The study identified and established the three sub-criteria of the BIM-PIMF model which are the BIM process level factors, BIM product level factors, and the key indicators for a successful BIM deployment on construction project sites. These criterias were semantically linked to the development of the BIM-PIMF framework on a five-point metric scale. The deliverables of this study include the development of the BIM-PIMF framework, together with its analytical scoring system. The findings of the study will improve the information channels of and ease the integration of technological innovations in construction processes while improving the technical competencies of project staff. The study highlighted a basket of effective recommendations and strategies to enhance the deployment of BIM throughout a project lifecycle. Policymakers and government departments can utilize the model in assessing the level of usage of BIM in a construction project as one of the useful measures in gauging which construction firms to be provided subsidies.

Although it has a widespread impact on the industry, the systematic implementation of BIM in projects faces challenges. This study integrated BIM into the lifecycle of a building project with the introduction of a conceptual framework constituted by BIM Information Flow, BIM Model Chain, BIM Workflow, BIM Institutional Environment, and BIM-based Project Management Information System (PMIS). This conceptual framework identifies the key areas for integrating BIM into the project lifecycle and explains how BIM works for project management practice. Through an ethnographic action research approach, the study developed a BIM roadmap for the project lifecycle by systematically implementing BIM in the building project. The major findings and pieces of evidence derived via the implementation support the conceptual framework. The following discussions explain how BIM disrupts the project from the view of organization design and clarify the contributions of this study in project management, as well as BIM adoption and integration. Finally, the conclusions focus on the development of this research, the role of the conceptual framework to underlie the BIM roadmap, and the research limitations. Recommendations are provided toward future research works.

The aim of the study is to evaluate and compare the current and desired level of the satisfaction of clients with the quality of projects delivered. 115 responses were received from construction professionals working in clients' organizations, and the data were collated and analyzed. The findings revealed that clients relate quality to compliance with specification and design standards. The results also showed that factors influencing project quality in the Nigerian construction industry are management commitment, regular inspections, and audits, skilled workforce. It is evident from the analysis that the current level of project quality delivery is quite lower than the desired level, and with wider gaps between the two factors of cost and timeliness. It is recommended that every participant in the construction project team should be conscious that projects must comply with specification and design standards which are significant to clients' perception of quality among others.

In addition, these two groups had the same education training, as there is no difference between the educational training of the consultantβs QS and contractorβs QS.
Originality/value β This study assessed the quantity surveyorsβ roles with regard to material management and waste minimization. It would add to the scanty research work in this area. The study has also successfully revealed the strategies that are to be adopted by the quantity surveyors to achieve value for money during the post-contract stage.
Design/methodology/approach β The study gathered the worldwide perceptions of 220 survey participants from 21 countries which were analyzed using descriptive and inferential analytical methods. The identified individual benefits of green BIM were further categorized into their underlying clusters using factor analysis.
Findings β The key benefits are related to enhancing project efficiency and productivity, ensuring real-time sustainable design and multi-design alternatives, facilitating the selection of sustainable materials and components, together with reducing material wastage and projectβs environmental impact, among others. The study analyzed and compared the perceptions of the diverse groups of the respondents as well.
Practical implications β Effective blueprints and insightful recommendations for enhancing the various stakeholdersβ capacities to implement green BIM in their construction projects were put forward to achieve the aim of sustainable smart urbanization.
Originality/value β The study identified salient benefits of the adoption of BIM and sustainability practices. The proper integration of these concepts and the execution of the recommended useful strategies by construction stakeholders, policymakers and local authorities will enable the built environment to reap the gains of its implementation.
Hope you are doing well.
