Evaluation of the building information modelling (BIM) implementation in construction projects on Lombok Island using analytical hierarchy process (AHP) and SWOT analysis

Abstract

Building Information Modelling (BIM) is a breakthrough in the construction world. BIM facilitates data validity with excellent visualization. In addition, data accuracy is also a major advantage of BIM applications for construction work. In this study, an evaluation of the implementation of BIM in construction work on Lombok Island was conducted. The evaluation resulted in strategies that can be applied to overcome obstacles to using BIM in the field. The data were obtained by giving questionnaires to 30 respondents spread across 4 large construction projects on Lombok Island. Furthermore, data processing was carried out by utilizing the Analytical Hierarchy Process (AHP) as a determinant of variables that influence the obstacles to the use of BIM and SWOT analysis to compile a method that is expected to be able to solve problems based on existing variables. Based on the data processing results, 21 variables were obtained, and six aspects were considered obstacles in the application of BIM. By ranking using AHP, 12 variables were obtained as a reference in determining strategies using SWOT. Then, seven strategies were obtained that can be applied to resolve the obstacles to applying BIM, as follows: Carrying out training activities to obtain a certificate of expertise; carrying out routine briefings to improve understanding of the duties and functions in BIM operations; improving the quality of human resources to overcome planning conventionally; procuring hardware following the regulatory standards of each application; procuring application licenses; recruiting BIM experts; and recruiting human resources to meet the requirements in BIM.
