Identification of critical barriers of industrialized building system (IBS) in construction industry: Analysis using the analytical hierarchy process (AHP)

Industrialized Building System (IBS) is one of the system that was widely used in construction since 1960.Many benefits when apply the IBS in construction but the level of construction in rural areas is still using conventional method compare than Industrialized Building System (IBS). The use of conventional method in rural area can cause a project take time to complete, produce the poor construction quality, and all the materials will be placed at the construction site.The purpose of this study to determine barriers to IBS implementation and identify the critical barriers that preventing the implementation of IBS in rural area projects.The methodology used is Analytical Hierarchy Process (AHP) method, in which set of questionnaire based on the pairwise comparison method are distributed to selected respondents. From this study, the result show that barriers for implementing IBS in rural area projects are quality design, cost, materials, building design, security of building, labour cost, environment control cost, quality of materials, materials cost, reliability of building, transportation cost, flexibility design of building, tangibility of building, supply of materials, and creativity design of building.The result also identify quality design as the most critical barrier that need further consideration the contractors. Expected findings of this study is for the policy makers or company may use the findings or guideline to formulate new policy or strategy in construction industry.In future research, the number of respondent are involve should be large to generalized the idea
