BIM-based Construction Networks (BbCNs) are teams comprising members from several specialist organisations to undertake BIM-related tasks on BIM-enabled projects. Fostering collaboration within BbCNs is a top priority for construction project managers, yet no explicit body of knowledge has focused on investigating the relevant research gaps in knowledge.The present study intends to address this gap by plotting the storyline of relevant research studies in the last 10 years (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016). A "Collaboration Pentagon" consisted of context, process, artefact, structure and agent as the theoretical lens is created through integration of relevant frameworks. The study draws upon a scientometric analysis of 1031 studies on BIM alongside the outcome of a qualitative evaluation of a total of 62 carefully selected papers on collaboration in BbCNs. The findings reveal that the scholarship on collaboration on BIMenabled projects has predominately focused on technology as one antecedent of collaboration while project-related and managerial antecedents have remained under-researched. Moreover, though enhancing collaboration necessitates inclusion of all influential antecedents, studies with such an all-inclusive perspective are non-existent. The study contributes to the field through this inclusive Collaboration Pentagon and by providing a systematic and objective evaluation of available literature on collaboration in BbCNs and uncovering respective gaps.

BackgroundThe functions of everyday life can stall due to disasters, irrespective of where the disasters take place, causing a wide range of consequences in a wide range of areas such as, human, economic, social, political, psychological and environmental concerns for communities. Disaster losses cannot be measured simply in monetary terms as the loss of lives is immeasurable and the impact on communities is either direct or indirect in nature. Disaster losses occur at all levels, from individual household losses to national and international level losses resulting from exceptional catastrophic events (UNDP, 2004).With the increase in natural and man-made disaster losses, policy makers, practitioners and the research community all over the world are seeking effective and efficient means of overcoming or minimising such losses. This has resulted in various theoretical constructs being introduced related to the disaster risk management domain. Although many of these theoretical constructs such as 'disaster risk', 'susceptibility', 'resilience', 'resistant', 'disaster risk reduction', 'vulnerability reduction', and 'hazard mitigation' have been advantageous for disaster management scholarship, they have failed to sufficiently address the triggering agents, functional areas, actors, variables, and disciplines pertaining to disaster events (McEntire et al., 2002). Aim of the paper'Disaster risk reduction' and 'vulnerability reduction' are commonly discussed topics in the current disaster management domain. They are used interchangeably to mean ways of overcoming and minimising disaster losses. In this context, this paper focuses on establishing a relationship between these two theoretical constructs to develop a holistic approach to disaster risk reduction with particular reference to improving its applicability in practical settings. Research methodologyThis paper is based on a literature review and an overall understanding gained through two case studies conducted on post-disaster infrastructure reconstruction projects in Sri Lanka and three expert interviews in the United Kingdom and Sri Lanka. The literature review and the empirical research explored 'the influence of integration of disaster risk reduction into infrastructure reconstruction on socio-economic development'.Both qualitative and quantitative data were collected and analysed to investigate the influence of integration of disaster risk reduction into infrastructure reconstruction on projects' and communities' vulnerability reduction. Two case studies were conducted within a water supply and sanitation reconstruction project and a road reconstruction project following the tsunami of 2004. The case studies consisted of a series of semistructured interviews and a questionnaire survey. The questionnaire survey was mainly conducted to triangulate the data gathered from the semi-structured interviews. It added depth to the study by using multiple sources of evidence. While the semi-structured interviews were analysed using NVivo (version 8) software, the ...

Purpose -Reality suggests that the whole world is currently facing an unprecedented scale of natural disasters. Sri Lanka fell into this category after being one of the hardest hit countries of tsunami 2004. Irrespective of the major losses that tsunami 2004 resulted in, Sri Lanka is prone to certain natural disasters such as floods, landslides, etc., which frequently bring in severe damage throughout the country. Within the context of continuous occurrence of hazards and growing vulnerability, risk reduction has become one of the important solutions to mitigate disasters and for speedy recovery after a disaster. Disaster risk reduction entails measures to curb disaster losses by addressing hazards and the vulnerability of people, to them. Disaster risk reduction measures can be categorised in various ways. From another perspective, achieving best quality through reconstruction has shown poor results. However, there is a clear two-way relationship between the concept of disaster risk reduction and quality of infrastructure, but it is not well explored. This paper aims to explore this issue. Design/methodology/approach -Research on which this paper is based focuses on the need for investigating and exploring the relationship between disaster risk reduction and quality of infrastructure. Accordingly, this paper presents the background of the study based on a critical literature review, mainly the rationale behind selection of this particular research and the expected research approach to be adopted. Findings -The findings suggest the notion that disaster risk reduction has an ability to influence the ultimate quality of a construction project, ultimately the success of the project. Originality/value -There is a clear two-way relationship between the concept of disaster risk reduction and quality of infrastructure, which is not yet well explored. This research will be further extended towards investigating this two-way relationship.

AbStrACt. the "construction output shock" that was generated by the massive reconstruction programmes after the Indian ocean tsunami in sri Lanka spread through the economic system and was reflected in economic indicators due to the multiple linkages that the construction industry has with other economic sectors. on the ground, it was observed that the prices of construction materials, labour and plant rose suddenly in the affected regions making the reconstruction effort more costly. this paper considers the responses of major economic and construction indicators to the construction shock due to post-tsunami reconstruction and the amount of time needed before they returned to an equilibrium state. Empirical results indicate that the construction output shock had a significant impact on material, labour and equipment price indices in the short run but other indicators showed only a very marginal response indicating that the remoteness of the disaster would have delayed the propagation.
