Key success factors implementing BIM based quantity take-off in fit-out office work using relative importance index

Abstract

Interior work is the last phase of a building project before it can be habitable. An important element of interior work is; 1. Function 2. success 3. Elements of Identity, branding, company priorities, and actualization. The need for office space that meet the requirements continues to increase discussing the use of materials to meet no 3 increasingly limited and constantly updated. Office Fit-Out work is directly related to the company's image and the productivity of its employees makes the budget for its construction so often in a large proportion. Like other construction work, a suitable work life cycle exiting the office will go through the design process, making Bill Of Quantity until the construction phase will go through the Quantity Take-Off process. Traditional quantity take-off takes time, low accuracy and create miscalculation, automatic take-off using BIM base Quantity take-off is a solution to help prepare cost estimation. Previous research found that a traditional take-off (manual take off) process took five times longer than the BIM Quantity Take-Off did. The quantity take-off for fit-out offices work has obstacles because the model for the Fit-out office building work has not been standardized. This study uses the Relative Important Index (RII) statistical tool to find the main factor that influences the BIM process of Quantity take-off with the results of the 10 sub factors that most influence the BIM Quantity take-off process.
