Information system design using labor productivity measurement for construction

Abstract

Labor utilization in construction project is the most critical because it costs 30-50% of the total cost. In many projects, the labors e.g craftman are hired outside the company. Contractors and owners need sufficient information related to those labors whom they will work with. It is necessary for clients understanding each labor productivity performance in order to achieve the project quality. This study aims to provide the infomation needed by designing an information system that can be easily accessed. This is also to support clients for decision making in terms of teamwork project involved. The level of productivity is measured by Labor Utilization Rate (LUR) using three variables: effective working time, contributory working time, and ineffective working time. Software Development Life Cycle (SDLC) is applied in designing the information system. The finding showed that information system is properly implemented to assist clients in determining workers using productivity calculation. The system can inform the recommended workers by calculating and sorting their level of productivity that support client's decision making towards construction workers.
