Cost perspective for sustainability in Industrialised Building System (IBS) projects

Abstract

Since 1998, the Construction Development Industry Berhad (CIDB) has been long promoting Industrialised Building System (IBS) in Malaysia. However, the use of IBS has not achieved an impressive number which only 10% and 50% have widely used in the past said CIDB in 2006. This research study focused on why IBS practice is still in an unconvincing market state of use and how sustainability in its cost perspective influences the use of IBS in each project. A questionnaire has been developed consists of four sections and has been distributed to 30 respondents in different IBS projects within the Selangor area in Malaysia. The data has been analysed using SPSS 23 software to determine the descriptive statistics and rank regarding the issues of implementing of IBS in the industry based on a cost perspective. The research study determined the level of understanding of IBS acceptance and awareness among the Malaysian construction industry. The findings encountered the main problems by constructions player while implementing IBS. In conclusion, strategies and recommendations are also suggested.

Polar modification‐enhanced interfacial compatibility for high‐performance rubber blends

“…4,5 However, due to the poor compatibility between different elastomers, improving the interfacial compatibility between polar and non-polar rubbers has been a research hotspot. 6 Styrene-butadiene rubber (SBR) and nitrile rubber (NBR) are the most commonly used non-polar and polar synthetic rubbers, respectively. [6][7][8][9][10] SBR has excellent mechanical strength, mechanical properties, aging resistance and wear resistance, and is widely used in various fields such as tyres, hoses, and medical instruments, with excellent comprehensive properties.…”

[11][12][13] However, the styrene-butadiene rubber contain no polar groups, but contains rigid benzene rings, which leads to an increase in the distance between the molecular chains, thus making it easy for solvent oil to destroy the three-dimensional cross-linked network after vulcanization.…”

Stakeholders' Perception on the Current Practices of Industrial Building System (IBS) Construction Technology

“…Studies have shown that costs are heavily impacted by a wide variety of variables, from the time of project estimation until the time of project completion. Studies by the previous studies [10][11][12][13], and others have found the elements that significantly influence construction costs in different nations. They argue that these aspects have a direct bearing on the construction organizations' responsibilities for managing the cost, socio-cultural, economic, external, technological, and political settings in which they operate, all of which have an impact on the construction costs.…”
