Challenges to BIM-Cloud Integration: Implication of Security Issues on Secure Collaboration

Emerging information technologies such as Building Information Modelling (BIM) offer the architecture, engineering and construction (AEC) industry enormous potential to develop collaborative workflows. Cloud computing has similarly gained popularity in the IT service provision for efficient web based data exchange and storage with enormous potential benefits for BIM, resulting in recent calls for their integration. Security and privacy concerns, however, continue to impede wide spread adoption of both technologies. The implication of real and perceived threats on secure collaboration is analysed systematically, towards formulation of a research agenda. It is observed that, secure collaboration threats within the AEC need appropriate characterization in relation to four levels of protective solutions, namely: infrastructure and technical, information partitioning and protection, legal and contractual management and relationship management. This will aid appropriate selection or adoption of the best available cloud technology offerings towards appropriate fit of BIM-cloud integration. Research towards formulation of this agenda is proposed through a high level project-based security or risk assessment framework for BIM-cloud integration and adoption.

Developing Capability of Public Sector Procurement in Ghana: An Assessment of the Road Subsector Client

The Ghanaian public sector procurement is experiencing a paradigm shift from a clerical role to a more strategic function targeting optimum achievement of value for money. For this to be fully realised, the skills of the workforce must be developed to meet contemporary expectations. Under-performance and misapplication of the public sector procurement function has been linked to a shortage of an adequately-skilled workforce. This study was designed to ascertain the nature and level of professional development required to enhance competencies of the workforce for successful delivery of the procurement function. The study employed questionnaires and interviews in a mixed methodology to collect data from the procurement management workforce within the Ghanaian Road Subsector. The findings of the study suggest weaknesses in key skill areas required of modern procurement practice which inhibit the achievement of maximum value for money. Up-skilling is recommended through appropriate training and continuous professional development with focus on the key areas identified.

Critical BIM qualification criteria for construction pre-qualification and selection

ABSTRACT Despite emerging research on Building Information Modelling (BIM) capability, there remain no studies that specifically look at criteria for the pre-qualification and selection of construction supply chain (CSC) firms for BIM projects. As a consequence, there is insufficient theoretical insight and empirical justification for critical BIM qualification criteria for the CSC context. In order to bridge this knowledge gap, a study was conducted to ascertain the most critical BIM capability attributes, as well as relevance to the pre-qualification and selection of suitable CSC firms for BIM-enabled projects. The relative importance of these criteria was determined based on their perceived influence on overall BIM delivery success on recent BIM-enabled projects. A sequential exploratory mixed methodological research design was adopted involving semi-structured interviews (n = 8) and a Delphi survey (n = 25) of experts, as well as a survey of CSC firms (n = 64) on BIM-enabled projects. The findings reinforce the criticality of past BIM experience in delivery success. Furthermore, it revealed that while technological infrastructure-related capacities (such as software and hardware availability) are perceived as very important qualification criteria, their actual contribution to delivery success is not as high in comparison to criteria related to previous BIM experience. This study provides insights on prioritising BIM capability criteria based on evidence on their contribution to delivery success in practice rather than their perceived importance as capability metrics.

Occupational safety and health management in developing countries: A study of construction companies in Malawi

Purpose. Whilst occupational safety and health (OSH) management is recognized as an important mechanism for addressing poor OSH performance, limited empirical insight is available on OSH management by construction companies in sub-Saharan Africa. This study investigated OSH management by construction companies (i.e., contractors) in Malawi in order to unpick implementation issues that need attention. Materials and methods. 46 OSH management practices were probed through a survey of contractors. Results. Implementation of OSH practices amongst contractors is low, particularly for practices related to the policy, organizing, measuring and reviewing, and auditing elements of OSH management. Company size is associated with implementation of nearly half of the 46 OSH practices. Certification of the company to Standard No. OHSAS 1800:2007 is associated with the implementation of fewer practices. Conclusions. OSH management improvement efforts would need to focus on the elements with particularly low implementation of practices as well as include initiatives that focus on helping microenterprises to improve their OSH management. The association between business characteristics and OSH management may be more evident with certain elements, such as the organizing element. Furthermore, certification to Standard No. OHSAS 1800:2007 may not necessarily translate into greater implementation of OSH management practices, especially in developing countries.

Design for occupational safety and health of workers in construction in developing countries: A study of architects in Nigeria

Purpose. Design for safety (DfS) of workers is amongst the prominent ways of tackling poor occupational safety and health performance in construction. However, in developing countries there is extremely limited research on DfS. This study thus makes an important contribution to the subject of DfS in developing countries by specifically examining the awareness and practice of DfS amongst architects within the construction sector of Nigeria. Materials and methods. A survey of architects, yielding 161 valid responses, was conducted. Results. While there is high awareness of the concept of DfS, the actual practice is low. Additionally, although there is high interest in DfS training, the engagement in DfS training is low. Significantly, awareness of DfS, training and education related to DfS, and membership of a design professional body have very limited bearing on the practice of DfS by architects. Conclusions. The findings are thus symptomatic of the prevalence of influential DfS implementation barriers within the construction sector. Industry stakeholders should seek to raise the profile of DfS practice within the sector. Furthermore, similar empirical studies in the construction sector of other developing countries would be useful in shedding light on the status of DfS in these countries.

Framework of performance measurement practices in construction companies in Egypt

Abstract Construction industry is considered as one of the most important sectors in Egypt. One of the major challenges faced by the industry, however, is the unavailability of suitable performance measurement systems for assessing companies’ performance. Modern performance assessment systems adopt a more universal approach to the measurement of construction company performance as opposed to the traditional project triangle. This paper aims to examine the practice of performance measurement in the Egyptian construction industry. Results show dominant role of in-house developed performance management systems as well as the use of KPIs as a method of performance assessment. The study further reveals that the highest importance is given to measures related to the time of project delivery, quality of works, clients’ satisfaction and profitability. Hence, the traditional project triangle of project’s success is the most prevalent approach to performance evaluation in the construction industry in Egypt. However, a shift towards a more holistic approach to performance assessment in larger companies was observed.

Infrastructure procurement skills gap amongst procurement personnel in Nigeria’s public sector

Purpose 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. Design/methodology/approach 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. Findings 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. Originality/value 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.
