THE APPLICATION OF STRUCTURAL EQUATION MODEL TO IMPROVE THE PERFORMANCE OF TIME IN CONSTRUCTION PROJECT
Abstract
The implementation of the Breeze Tower Apartment Project, South Tangerang, lndonesia, especially for Architecture work that was delayed due to the owner’s shop drawing investigation was not compliance with the plan, only 77 percent of the total work was completed. Based on that, this research needs to be done to determine alternatives to improve the project time performance by analyzing the causes of the project delay so that losses caused by delays can be minimized. To find out the alternative solutions to improve project time performance towards the most dominant caused of delay where the research was conducted at the Breeze Tower Apartment Project, South Tangerang, lndonesia. Modeling for this research using the software SEM SMARTPLS 3.0. version. Based on the analysis of structural models or path analysis in SEM Smart PLS, it was found that the most dominant cause of delay was the value of the path coefficients between the independent variables and the dependent variable with a value of 0.548, namely design and documents. Based on the results of expert validation, alternative solutions in increasing project time performance against the most dominant caused of delay are designs mat should go through a number of discussion processes to finalize the design, and the design planner must have a comparable design publishing target and in accordance with the target of carrying out the work by proposing the changes to the new design that most relevant to the field conditions, and includes analysis on each alternative design change. This research is limited to reviewing the causes of project delays, especially in architecture work that affects the time performance of the Breeze Tower Apartment Project, South Tangerang, lndonesia. The substance of the study describes 4 factors including material, equipment, environment, human resources to review the most dominant causes of project delays. Quantitative analysis in this study uses SEM Smart PLS tools where the studies raised will focus on architecture work to obtain the alternative solutions to improve the project time performance towards the most dominant causes of delay where this research is carried out on the Breeze Tower Apartment Project, South Tangerang Indonesia.
