Analysis of The Influence of Labor, Materials, and Site Characteristics on Individual Performance and Time Performance in The Implementation of Steel Frame Bridge Projects

Understanding the impact of project time performance on individual performance is key to demonstrating reliability, commitment, and valuable time management skills. This study aims to To find out, obtain, and analyze the influence of labor, material and site characteristics on individual performance of steel bridge construction projects, find out get, and analyze the influence of labor on Individual performance, find out get, and analyze the influence of material on Individual performance, find out get, and analyze the influence of site characteristics on Individual performance, find out, obtain, and analyze the influence of individual performance on time performance. find out, obtain, and analyze the control of labor factors, site characteristics, and materials on individual performance and time performance of steel bridge construction projects. The type of research used is quantitative research, with a sample size of 100 people consisting of contractors, consultants and suppliers, with regression analysis assisted by spss 21 software and path analysis with SmartPLS 4 software. The results of the study of labor, materials, and characteristics of the place together have a significant effect on individual performance in bridge construction projects, labor has a positive and significant effect on individual performance in bridge construction projects, materials have a positive and significant effect on individual performance in bridge construction projects, characteristics of the place have a positive and significant effect on individual performance in bridge construction projects, individual performance has a positive and significant effect on time performance in bridge construction projects and Control of labor factors.
