Public organizations responsible for building permits are increasingly considering the potential applications of Building Information Modelling (BIM) in their workflows, but BIM adoption still remains a complex challenge. This research aims to investigate the factors affecting BIM adoption for building permits through a case study of a public organization currently developing and piloting a BIM-based building permit process. A thematic analysis of semi-structured interview data revealed ten factors that influence BIM adoption for building permits: complexity (in both development and use) of a BIM-based building permit system; relative advantages/disadvantages of BIM for building permits; the existing building permit system; management support for a BIM-based building permit process; organizational culture; BIM awareness; training and learning; available expertise for a BIM-based building permit process; external pressure; and legal context. The findings are important for public authorities’ understanding of both the enablers and challenges of the BIM-based building permit process, and have practical implications for professionals in public authorities in particular, and also the Architecture Engineering Construction/Facilities Management (AEC/FM) industry in general, to guide their steps towards adopting BIM. This research also highlights the potential benefits of BIM adoption for the building permit process.

BIM adoption is a complex process and relatively little information exists on the BIM adoption processes of public authorities. This research aims to address this gap by examining how a contemporary public authority is approaching BIM adoption for their building permitting process. Firstly, a systematic literature review was carried out to understand extant descriptions of BIM adoption processes and the factors affecting adoption success. This resulted in the derivation of a generic BIM adoption process and the classification of factors that affect BIM adoption with reference to the Technology Organization and Environment (TOE) framework. The case of the BIM adoption process and the factors affecting its implementation in a contemporary public authority were then analysed in terms of the generic adoption process and factor classification derived from the literature. The findings reveal the planning strategies and execution steps for BIM adoption and the factors affecting them. This study provides a systematic approach to investigating BIM adoption in a public authority. It contributes to the understanding of BIM adoption processes and factors affecting them and is anticipated to be useful for AEC/FM professionals in understanding and facilitating successful BIM adoption.

Cost overrun is an increase of cost of project from approved budget which was signed by parties at the time of tender. Cost overrun in construction of highway projects is a common problem worldwide and construction industry of Pakistan is also facing this crucial problem of cost overrun in highway projects of Pakistan. The main objective of this research is to identify the causative factors of cost overrun in highway projects of Sindh province of Pakistan. A well designed questionnaire was developed based on 64 common factors of cost overrun from literature review. Developed questionnaire was distributed among selected 30 experts from owner/client, designer/consultant and contractor who have experience more than 20 years' experience in highway projects. The collected data was statistical analyzed. After analysis results showed that delay process in payment by client, inadequate planning, client interference, poor contract management, delay of decision making, change of scope of project and financial problems faced by client were most causative factors of cost overrun in highway projects. This research will provide alertness to stakeholders of highway projects of Sindh province to avoid cost overrun in projects.

Any construction practitioner fundamental goal is to complete the projects within estimated duration and budgets, and expected quality targets. However, time and cost overruns are regular and universal phenomenon in construction projects and the construction projects in Malaysia has no exemption from the problems of time overrun and cost overrun. In order to accomplish the successful completion of construction projects on specified time and within planned cost, there are various factors that should be given serious attention so that issues such as time and cost overrun can be addressed. This paper aims to construct a framework for the causes of time overrun and cost overrun in construction projects of Malaysia. Based on the relevant literature review, causative factors of time overrun and cost overrun in Malaysian construction projects are summarized and the theoretical frameworks of the causes of construction time overrun and cost overrun is constructed. The developed frameworks for construction time and cost overruns based on the existing literature will assist the construction practitioners to plan the efficient approaches for achieving successful completion of the projects.
