The traditional safety management approach is a control-oriented approach that seeks to direct and control workers to complete the expected company safety standards and regulations. This reactive approach to safety management is only partially compatible with the growing complexity of contemporary organisations. Therefore, a more comprehensive and modern approach is necessary, hence, the resilience management system. This study is part of a PhD programme. The study’s objective was to establish the level of resilience capabilities of construction safety management systems in Ghana’s construction industry. The targeted respondents were health and safety managers, managing directors, project managers, site engineers, and construction managers of D1K1, D2K2, D3K3, and D4K4 construction companies. The list of 144 construction companies surveyed in this study was obtained from the Association of Building and Civil Engineering Contractors Ghana and deemed to be in good standing. The study used purposive sampling techniques to reach out to the respondents. Descriptive statistics, a one-sample t-test, a one-way analysis of variance and its post hoc test, and the resilience analysis grid were employed. The results revealed that out of the seven safety management systems assessed, only ‘policy’ measured up to the acceptable level of resilience, thus establishing that the entire safety management system is not resilient. These findings have empirically established that safety management systems in the Ghanaian construction industry are not resilient. The results further highlight the necessity for contractors and stakeholders to switch from a conventional safety management strategy to a more proactive safety management approach and to establish a customised method to foster a robust safety management system.

This exploratory study investigates the implementation of capital budgeting practices (CBP) by selected public-sector construction firms (PSCFs) in Tanzania. This investigation seeks to assess the extent, to which such practices are used for effective investment decision-making, with a particular focus on the country’s housebuilding sector. A case study research design was adopted to collect data from five Tanzanian PSCFs, serving as cases through a mix of questionnaires, interviews, and document reviews. The emergent data was analysed using thematic analysis. An appreciable level of CBP implementation was observed in all the cases. The Internal Rate of Return (IRR), Net Present Value (NPV), and Payback Period (PBP) capital budgeting techniques (CBTs) were observed to be mostly used by these PSCFs, while sensitivity analysis was widely deployed for risk mitigation. The influence of top management in decision-making, political influence, and lack of advanced software were some of the implementation challenges identified. The findings contribute to the elucidation of CBP implementation praxis in the public sector organisation context in developing countries, as it relates to the housebuilding industry in Tanzania’s unexplored context. The study proves to be a valuable resource for public sector entities in developing countries intent for facilitating effective investment decision-making about infrastructure procurement, and it contributes to improving knowledge of CBP implementation, consideration of risk mitigation factors, and post-project implementation audits by public sector firms.

Open spaces are essential to the liveability of urban residential neighbourhoods. While formal open spaces, including neighbourhood parks, have been extensively studied for their environmental and social values, there is scanty research on marginal open spaces' potential uses and benefits. Drawing on an empirical study of residential neighbourhoods in a Nigerian urban centre, this study explores the temporary appropriation of marginal open spaces. The study adopts a mixed-method approach using a questionnaire survey, photographic recordings, observations, open space measurements, and interviews with local planning authorities (LPAs). Findings showed that marginal spaces exist in various types and forms, including open areas along neighbourhood streets and stream corridors. The three major types of temporary appropriation in the residential neighbourhoods were informal commerce, leisure/social pursuit, and sacralisation (religious activity). The most critical concerns regarding open space appropriation, measured on a fivepoint Likert scale, were lack of safety, absence of tree cover/shade, and stench from uncollected waste, with scales of 4.92, 4.68, and 4.42, respectively. Information gathered from the LPAs also showed that the users violated the planning regulations guiding the marginal spaces. The study concluded that although the temporary use of open spaces in residential neighbourhoods is essential for improving the residents' livelihoods and socio-cultural lives, the practice is fraught with several challenges. Consequently, practical policy recommendations were proffered to ensure that marginal spaces are produced as desirable areas for everyday life while maintaining hygiene, safety, cleanliness, and comfort.

This study was motivated by the need to deploy building information modeling (BIM) and its technologies to improve the realization of construction projects. Prior to the introduction of BIM, the construction industry was confronted with obstacles and was sluggish in adopting change. Until recently, existing BIM research has mostly focused on large enterprises, and there has been an apparent pattern of underrepresentation of medium-sized firms in BIM-related studies. Thus, the purpose of this paper is to investigate the major hindrances to BIM’s adoption in construction projects as well as the dynamics of these hindrances in a developing country like Nigeria, using the total interpretive structural modeling (TISM) approach. The TISM displayed an eleven-level hierarchy of hindrances made up of independent, dependent, and linkage categories. Based on the MICMAC analysis, "lack of skilled BIM personnel" had the highest driving and the lowest dependence (independent) power, thus indicating its importance in the adoption of BIM. The findings further showed that "lack of awareness of BIM" and "resistance to change" are critical for the adoption of BIM in construction projects. The drivers (dependents) for the ease of adoption of BIM by policymakers and practitioners within the built industry are thus defined in this study. This study contributes to the early studies of BIM adoption from a developing country’s perspective.

Inadequate transportation infrastructure is a significant obstacle to any economy's growth and development potential. A primary challenge to sustainable delivery is finance. Concerns about the efficacy of innovative mechanisms for financing infrastructure investments, primarily through public-private partnerships (PPP) abound in the literature and practice. Few studies focus on the critical success factors (CSFs) for PPP transport projects in emerging markets. This paper aims to identify the taxonomy and manifestations of CSFs associated with executing PPP-based transportation projects in developing countries. The study collected and analysed data using a questionnaire and in-depth interviews using a mixed-methods sequential explanatory investigation among built environment professionals, including general contractors, consultants, and government agencies. Findings indicated that good governance, the project's technical feasibility, the commitment of the public and private partners, appropriate risk allocation and sharing, and experience were the most critical success factors. Multivariate techniques using factor analysis identified four principal components: partnership and procurement, economic and governance technical, and political and social factors. The study contributes to the body of knowledge using mixed methods within an underexplored context, developing countries. The findings could be extended further using more robust statistical techniques. The localisation conditions for the effective delivery of transportation projects should be considered.

The purpose of this study is to assess the challenges and develop a regulatory framework for sustainable development of Micro and Small Enterprises (MSEs) in the construction industry. A structured questionnaire was used to collect the quantitative data and a semi-structured interview was conducted to get detailed insight about the MSEs development. Descriptive analysis was used for the quantitative data analysis and the qualitative data was analyzed thematically focusing on the challenges and applicable regulatory instruments. The identified internal challenges are associated with management practice, financial capacity, and technical capacity. The external challenges are ineffective policy support and regulation, week registration practice, and demand and price fluctuation. Considering these findings, an improvement regulatory framework with four pillars is developed. Pillars of the improvement regulatory framework are registration and follow-up, access to markets, access to finance, and training and advisory. The identified internal and external challenges are interrelated and situation dependent, therefore, continual monitoring and controlling of the operating environment would help to ensure sustainable development of MSEs. The nature of construction industry in developing countries shares common characteristics, hence the findings and the developed improvement framework can be extended to similar contexts.

This study sought to examine the occurrence of, and the most critical factors that cause, budget overruns in Ghana’s telecommunications industry construction projects by applying an exploratory sequential mixed method approach. A multiple case study approach was initially adopted to ensure a greater understanding of the differences and similarities between four cases drawn from companies engaged in the construction of network expansion projects. This was followed by a survey of 230 practitioners responsible for managing construction projects within the industry. The software programs, Atlas ti, SPSS, and AMOS version 25.0, were used in the data analysis. An exploratory factor analysis and a structural equation modelling were performed to test and validate the hypothetical model developed to illustrate the most critical factors that cause budget overruns. The findings resulted in the final model dubbed ‘Budget Overrun Flowerpot’, provides practitioners with better understanding of the most critical causal factors that need to be managed appropriately to improve project efficiency and budget performance.

The adoption of the Internet of Things (IoT) is essential because it facilitates project information, saves time, and cost and reduces risks on construction sites. The objectives of the study are to investigate the adoption, application, and challenges of IoT technologies in the Rwandan construction industry. The survey research design (open and close-ended questionnaire) was adopted for the study. The questionnaire was administered to registered construction professionals in Rwanda. The stratified random sampling technique was adopted for the study. The data for the study was analysed with frequencies, mean scores and student t-tests. The findings of the study indicated that none of the IoT technologies was well adopted, two were adopted, eleven were averagely adopted and twenty-two were slightly adopted. Also, IoT technologies were used for project management, efficient transportation, time management, and production of site plans. The significant challenges with the adoption of IoT technologies were a lack of training centres, lack of IoT awareness, lack of expertise, poor network connectivity, a requirement for extra budget to acquire IoT technologies, and poor collaboration among construction stakeholders. The study concluded that the level of adoption of IoT technologies in the Rwandan construction industry is low and there is no difference in the opinions of the respondents on the adoption and challenges of adopting IoT technologies in the construction industry. The study recommended that there is a need to create more awareness of the adoption of IoT technologies, and enact laws and policies that can foster the adoption of IoT technologies in the construction industry.

Technological development has placed pressure on Construction Industry (CI). Reviewing its activities due to increase in a globally competitive market has manifested from the changing need of the construction environment in meeting customer satisfaction. These pose challenges to many construction industries in the developing countries to improve on the quality of the product produced in meeting the customer need. The study aims to examine the impact of Information Technology (IT) application on Value Re-engineering (VRE) implementation that gives rise to customer Value Addition (VA), through enhanced profitability performance and cost reduction for the CI to offer benefit for customers to achieve satisfaction. The subjectivist methodology was utilised to establish critical success factors in forty purposefully sampled building construction operators within Abuja using purposive sampling techniques. The result further revealed that quality design and Collaborative Working (CW) among the VRE practitioners help the customer to derive the benefit of waste reduction by achieving value-added perspective through the use of high technology that influences both design and construction operations for the project. Early dissemination of information and design adequacy reduces pressure on both materials and labour scarcity. Finally, there is a significant need for the construction process to be re-engineered through the utility of change enablers, and the introduction of assistive technologies like IT as drivers of VRE implementation on VA that give rise to customer-derived benefits.

: The present paper attempts to identify and assess the individual perceptions of BIM benefits and implementation barriers in the construction industry in Algeria from architects’ perspective. An investigation was carried out through survey questionnaires distributed to Algerian architects with different profiles. A total of 100 questionnaires were used for the study. A subgroup analysis was conducted in order to investigate the differences in the individual perception of the different groups of architects segmented according to the respondent’s work type, organisation size, experience length, and CAD and BIM knowledge. The findings of the study revealed that the most important barriers to BIM implementation were people and policy factors. The subgroup analysis revealed that the architects working for design firms were more aware and had more readiness for adopting BIM, compared to those working for project owners and contractors. Moreover, there were differences in the BIM maturity level between the big size and small size organisations in Algeria. It was concluded that, in the actual BIM maturity level, the BIM implementation would not occur without the implication of local authorities and policymakers as they have a significant impact in promoting and accelerating BIM adoption in the country.
