TL;DR: In this article, a study was conducted to determine the influence of BIM benefits from the Malaysian construction stakeholders' perception towards its implementation, which revealed that most of the construction companies lack of awareness about BIM technology and its implementation could significantly increase project productivity and performance.

TL;DR: In this article, the authors present results of the still ongoing study which is in relatively under-researched area and examines the global perception of sustainable construction project risks, and compare different stakeholders' evaluation of risks and stakeholders influence on project success.

TL;DR: In this paper , the authors analyzed 108 fall fatalities in Malaysia from 2010 to 2018 to find the critical, relevant variables, including financial constraints, job complexity, dangerous working procedures, unguarded edges/holes at higher elevations, and rushing to complete the job.

TL;DR: In this article, a study was conducted to determine the rate of occurrence of fatal accidents after BIM implementation in Malaysia, and the results indicated that the types of accidents identified are similar to that of most countries in the world.

Abstract: Disposal of palm oil mill waste material has become a significant factor impacting the environmental situation. Among the palm-oil waste the Palm Oil clinker (POC) is usually discarded in the landfill with no economic use. The use of waste materials as modifiers for bitumen mixtures is one of the better alternatives. For this study, the impact of short-term aging on Palm oil clinker fine (POCF) modified asphaltic mixtures was investigated. The POC chunks were initially grounded and sieved through the British standard (BS) 0.075 mm sieve to obtain the POCF that can be utilized as a bitumen modifier at 4%, 6%, and 8% by weight of bitumen. In this investigation, 4.9% optimum bitumen content was selected with a 60/70 penetration grade bitumen to investigates the properties of the POCF on the ACW 14 modified asphalt mixture before and after aging. The study implemented a laboratory simulation of short-time aging (S-TA). Volumetric and Marshall properties were evaluated and analysed to compare the unaged and aged samples. Furthermore, the regression model validates significantly (R2 value 0.89-0.99) that variation in the aging condition and POCF content is directly related to the variation in the Marshall and volumetric properties. The investigation shows that the aging condition and POCF content had a significant effect on voids, Marshall stability, and Marshall quotient, as the S-TA sample showed better results compared to unaged this finding was also verified by ANOVA analysis. The research finding indicates that mixtures with POCF-MB have better performance as compared to conventional mix even under S-TA.
