Effective procurement of infrastructure is linked to the attainment of the sustainable development goals set by the United Nations. While the capacity of organisations is generally thought to be related to organisational performance, there is a lack of empirical insights concerning the contribution of procurement capacity of public organisations towards the attainment of procurement objectives in infrastructure procurement. Thus, it is unclear which aspects of the capacity of public procurement organisations contribute the most to the attainment of procurement objectives in the procurement of infrastructure. This research sought to address this gap.

The research used a survey of public procurement professionals which yielded 590 responses.

Exploratory factor analysis of 23 organisational capacity items revealed three components of organisational procurement capacity: “management of the procurement process”; “human and physical resources”; and “financial resources and management”. Multiple regression modelling of the relationship between the components and the attainment of 12 procurement objectives further reveals that there is a significant positive relationship between the three components and all the objectives. However, “management of the procurement process” emerged as the greatest contributor to the attainment of seven objectives, whereas “human and physical resources”, and “financial resources and management” were the greatest contributor to the attainment of one objective and four objectives, respectively.

The study provides strong empirical justification for investment in the development of procurement capacity of public agencies involved in procurement of infrastructure. Furthermore, procurement capacity development of specific capacity components can be prioritised based on the relative contribution of capacity components to the attainment of desired procurement objectives. This should be useful to government policymakers as well as multilateral organisations that fund infrastructure and procurement reforms in various countries.

The achievement of sustainable development goals is linked to the procurement of public infrastructure in a manner that meets key procurement objectives, such as sustainability, value-for-money, transparency and accountability. At the heart of achieving these procurement objectives and others is the capacity of public procurement institutions. Whereas previous reports have hinted that there are deficiencies in procurement capacity in Nigeria, insights regarding critical aspects of organisational capacity deficiencies among different tiers of government agencies is limited. The purpose of this paper is to investigate the critical gaps in the procurement capacity of state and local government agencies involved in the procurement of public infrastructure in Nigeria.

The study employed a survey of public infrastructure procurement personnel which yielded 288 responses.

Among 23 operationalised items that are related to organisational procurement capacity, none is perceived to be adequate by the procurement personnel. Additionally, among 14 procurement objectives only 1 is perceived as being attained to at least a high extent.

The findings underscore the acuteness of organisational procurement capacity weaknesses among public procurement institutions within Nigeria’s governance structure. It is, thus, imperative for policy makers within state and local government to formulate, resource and implement procurement capacity building initiatives/programmes to address these deficiencies. Additionally, the organisational procurement capacity items operationalised in this study could serve as a useful blueprint for studying capacity deficiencies among public infrastructure procurement agencies in other developing countries, especially within sub-Saharan Africa where several countries have been implementing public procurement reforms.

Designers have a key role to play in the Prevention through Design (PtD) practices in construction projects. Nonetheless, previous studies indicated that the issue of competencies to perform and sustain such practices over time is of a significant concern. This study aims to explore the key attributes of designers' competencies for PtD practices in construction.

By using the Scopus database, a total of 86 papers related to PtD in construction published in peer-reviewed journals were reviewed and analysed using the well-established systematic literature review (SLR) methodology.

The review indicates that in order to be competent in PtD implementation, designers need to be equipped with tacit and explicit knowledge, technical and soft skills and experience related to PtD. Furthermore, the review identifies attributes of these competencies. Additionally, a framework that links key PtD elements/principles with the PtD competencies is presented.

The findings would enable contribution to the industry by providing the necessary references for design organisations to improve their designers' PtD competencies and hence, be able to meet their responsibility under relevant occupational safety and health (OSH) legislative framework.

This study extends the PtD literature in the construction context by providing deeper insights into the conceptualisation of relationship between competent designers and PtD elements. The novelty also lies in the consolidation of PtD competency attributes for designers in construction that could act as a reference for any future developments related to PtD competency assessment for designers.

The emergence of building information modelling (BIM) has led to the need for pre-qualification and selection of organisations capable of working within a BIM environment. Several criteria have been proposed for the assessment of an organisation’s BIM capability during the pre-qualification and selection phase of projects. However, no studies have sought to empirically establish whether organisations selected on the basis of such criteria have actually been the most successful at delivering BIM on projects. The purpose of this paper is to address the aforementioned gap through a comparison of predicted BIM capability and post-selection performance.

BIM capability of firms in a case study was predicted using 28 BIM pre-qualification and selection criteria, prioritised based on their perceived contribution to BIM delivery success from a survey of practitioners on BIM-enabled projects. The comparison of predicted BIM capability and post-selection performance was, on the other hand, achieved through the application of the Technique to Order Preference by Similarity to Ideal Solution and fuzzy sets theory (Fuzzy-TOPSIS).

Findings underscore the reliability of the 28 BIM pre-qualification and selection criteria as well as the priority weightings proposed for their use in predicting BIM capability and likelihood of performance. The findings have highlighted the importance of criteria related as previous BIM use experience as well as information processing maturity as critical indicators of the capability of organisations, particularly design firms.

Overall, the findings highlight the need for prioritisation of BIM pre-qualification and selection criteria on the basis of their actual contribution to delivery success from post-selection evaluation of performance.

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.

Work on construction sites involves individuals with diverse character, temperament,age, physical strength, culture, religion and experience level. A good number of these individuals are also alleged to involve themselves in substance and alcohol abuse due to the physically demanding nature of their work. These could promote the prevalence of violence on construction sites which could in turn affect safety on construction sites. However, there is a lack of empirical insight into the effect of violent behaviour and unsafe behaviour on construction sites. This study therefore pioneers an empirical inquiry into the relationship between violent behaviour and unsafe behaviour on construction sites.

Seventeen violent behaviours and 15 unsafe behaviours were measured on 12 construction sites among 305 respondents using a structured questionnaire. A total of 207 valid questionnaire responses were collected from site workers. Partial least square–structural equation modelling (PLS-SEM) technique was used to examine the relationship between violent behaviour and unsafe behaviour.

The results indicate that there is a significant positive relationship between violent behaviour and unsafe behaviour on construction sites.

The findings from this study provide valuable insight into a less investigated dimension of the problem of construction site safety management. A focus on attitudinal issues such as how workers relate toward others and toward self should be an important consideration in safety improvement interventions on construction sites.

The Furniture, Fixture and Equipment (FFE) sector is well placed to leverage virtual reality (VR) technology for competitive and operational advantages; however, the diffusion of VR applications in this sector has followed a steep curve. This study reports on the implementation of two novel VR applications in the FFE sector and also investigates the challenges and benefits associated with their use and adaptability.

A sequential exploratory mixed research methodology consisting of three phases was adopted for this study. This included identification of factors that affect/facilitate the implementation of VR (Challenges and Benefits) using experiments during in-house prototyping of VR applications, a rigorous literature review and questionnaire survey to solicit FFE Stakeholder's (n = 117) opinion on the utility and usefulness of the proposed applications and to the understand factors that facilitate and inhibit their implementation in FFE's context, particularly as a design communication and coordination tool.

The findings of this study revealed that distributed and single-user VR has become essential to digitalising the FFE sector's design communication with improved design communication being regarded as the most important benefit of its use. Conversely, the most critical challenge that inhibits the implementation of these two VR applications in the FFE sector is the perceived cost.

This study provides valuable insight to FFE's stakeholders to devise action plans to mitigate myriad complex and interrelated factors that affect the adoption of virtual reality technology in the FFE sector that are otherwise very hard to understand, and the consequential implementation of any mitigation plans cannot be devised.

Although building information modelling (BIM) adoption in developed countries has largely been incentivised by government, in developing countries, adoption is often driven by desires of industry professionals, which is dependent on awareness of BIM and availability of skills among the professionals. Thus, BIM awareness and competence among professionals have become useful baseline measures of BIM readiness. To ascertain BIM readiness within the Seychelles construction industry, this study aims to investigate the level of BIM awareness and level of BIM competence among construction professionals.

The study involved a questionnaire survey of construction professionals (n = 96) and data analysis using both descriptive statistics and association analysis.

The results indicate a moderate level of BIM awareness, but a low level of engagement in BIM education/training. Also, the professionals have very low BIM technical skills, notably the ability to use BIM-related tools and to perform BIM-related task. Furthermore, this study suggests that the experience of working on collaborative projects could be a useful premise for BIM implementation among construction professionals.

The implication is that construction professionals in the Seychelles need to start readying themselves for greater BIM adoption by taking steps to address the BIM technical skills deficiencies and the low engagement in BIM education/training.

In spite of emerging research on building information modelling (BIM) capability assessment, there is a general dearth of knowledge about the links between often pre-emptive capability measurement attributes and actual delivery success. More so, current studies have not considered success from the wider construction supply chain (CSC) perspective. So far, the perceived importance of capability metrics is not based on post-project evaluations of their contribution to BIM delivery success. This paper aims to identify relevant BIM capability attributes used for qualifying CSC organisations for projects and further aims to investigate their relative importance and influence on some key aspects of BIM delivery success.

Based on heretofore validated set of BIM capability attributes from semi-structured interviews and a Delphi study, a survey of CSC firms on BIM-enabled projects was used to model the influence of BIM capability attributes on BIM delivery success. Multiple regression modelling was performed to ascertain the nature of the relationship between BIM capability attributes and the key aspects of BIM delivery success as identified from the literature.

BIM staff experience and the suitability of proposed methodology prior to project commencement were identified as the most influential on BIM delivery quality, as well as delivery within schedule and on budget. Conversely, the administrative and strategic-level capacities were found as the most influential in leveraging collaboration, coordination or integration of the CSC on projects through BIM.

This study provides a step change in prioritising BIM capability criteria based on evidence of their contribution to delivery success in key performance areas, rather than their perceived importance as capability metrics as widely practised.

Procurement of public infrastructure that is fit for purpose partly depends on the competencies of procurement personnel. In many developing countries in Sub-Saharan Africa, including Nigeria, there is a deficit in the quantity and quality of infrastructure and their procurement is further riddled with deficiencies in the capacity of public procuring entities. The purpose of this study was to ascertain the critical skills development needs of public personnel involved in the procurement of infrastructure in Nigeria.

Based on a quantitative research strategy, this study sought to address the knowledge gap through a survey of public infrastructure procurement personnel (n = 288) in different tiers of government (i.e. state and local government) and geopolitical contexts (north and south) in Nigeria.

Of the 45 procurement skill areas operationalised, there is need for further development in 38 of them including: computing/ICT; problem-solving; communication; decision-making; health and safety management; quality management; relationship management; team building; project monitoring and evaluation; time management and procurement planning.

A key implication of this study is for policymakers in state and local government to formulate and implement infrastructure procurement capacity development reforms that address the competency gaps of procurement personnel. Such reforms need to take into account the suitable methods for developing procurement competencies. Additionally, the procurement skill areas operationalised in this capacity assessment study could serve as a useful blueprint for studying capacity deficiencies amongst public infrastructure procurement personnel in other developing countries.
