Building information modeling (BIM) application has the potential to revolutionize the quantity surveying practice. It appears that quantity surveyors are still lagging behind in BIM application compared to other professionals. Low adoption among quantity surveyors is due to lack of awareness of the potential of BIM application toward their profession. Quantity surveyors are still unsure of the capability of BIM in their practice. It is still generally underexplored how BIM application contributes to quantity surveyors performance improvement. This research attempts to identify the capabilities of BIM application in quantity surveying practice to increase awareness. The scope of this research limited to pre-construction stage. The potential capabilities are found through literatures and verify through interviews with eight quantity surveyors till achieve saturation. The findings indicated that there are 11 potential BIM capabilities that can enhance quantity surveyors' performance and majorities of them are confirmed by the interviewees. These findings provide clear understanding that BIM application has the capabilities to enhance quantity surveyors' performance where traditionally their works are known as time-consuming and error-prone.

Abstract. Building Information Modeling (BIM) is a new buzzword that is gaining a momentum within the construction industry in Malaysia, and worldwide. BIM is a way of working that involves the automation of the entire project team using a 4D model that can do many of the traditional fuctions of a Quatity Surveyor (QS). As BIM is removing more of the traditional work of QS, there are rising fears that it could threaten the viability of the QS professions especially for small firms that still rely on producing bills of quantities. This paper aims to review the challenges and opportunities gained from BIM advancement in QS profession, especially in Malaysia. Despite of serious cost and commercial challenges of BIM implementation, BIM will work wonder as a tool that will cut the amount of time QS have to spend on analysis and provides opportunities to direct QS talents towards being more efficient. This is resulting to better project coordination with a lot less conflict, a more sustainable building in the final instance and also throughout the process, as less time is spent on each stage.

Abstract. There is increasing demand on sustainability-led design to reduce negative impacts brought by construction development. The capability of Building Information Modeling (BIM) to achieve sustainability is widely acknowledged. Various sustainability analysis and calculation can be performed at early stages to help the designers in decision making. However, the level of implementation is still not popular in the construction industry. Many of the industry players are still rely on traditional 2D method for designing and analysis. Hence, this study aims to demonstrate a proof concept of using BIM for sustainability design. The first phase of this study conducted a critical review of existing assessment schemes: BREEAM, LEED, SBTool, CASBEE, BEAM Plus, Green Star, Green Mark and GBI, to develop a set of main criteria to be considered for sustainability design. The findings revealed that fourteen criteria are considered, which are management, sustainable site, transport, indoor environmental quality, energy, waste, water, material, pollution, innovation, economics, social, culture and quality of services. It was found that most of the existing schemes emphasized on environmental aspect as compared to economics, social and culture except SBTool. The next phase of this study will conduct a case study to demonstrate sustainability design through BIM by using the criteria developed from the first phase.

PurposeClimate change and global warming have increased concerns over the influence of weather on workers' health and productivity in construction projects. A significant number of studies can be found in the weather and productivity interplay area. The purpose of this paper is to review the recently published papers in this area to explore the trends of research and topics discussed and to determine knowledge gaps and directions for future research.Design/methodology/approachRecent papers published between 2014 and 2019 were synthesized, reviewed and analyzed using bibliometric and text mining analysis.FindingsThe results revealed the trends of publications, the main authors contributed to this area and countries that attracted most of the research papers. Based on the review, this study presented a taxonomy of studies consisting of seven clusters, namely productivity management, seasons, weather factors, participants' conditions, uniform and clothing, work time and health and safety.Originality/valueThis review paper sheds a light into the topics discussed in this area, the interrelationship between the topics and the significant topics that should be continued in the future. Global warming concerns necessitate the need for more studies in tropical countries and countries that are expected to expose to high temperatures and heat stress, which greatly impact labor productivity. The paper highlighted the need to understand how weather influences workers' psychological conditions and subsequently their productivity.
