Abstract

Mechanical electrical and plumbing (MEP) job is a job in construction project and the implementation is conducted after the workers conduct structural work. The use of materials has an important part from project total cost because waste will be happened if it is used uncontrollable. The aim of this study was identifying JIT application to electrical work in Leedon Hotel Surabaya. The condition before the researcher implemented JIT in Leedon Hotel project, it was identified waste caused by design change, lack of coordination between project and Head Office, and materials availability with excess material stocks. The limited size of the warehouse as MEP materials storage made the material storage not optimal and it had potential to be waste. Applying just in time concept had a focus on waste elimination by planning - needs - use in the field based on the application of JIT method in the Leedon Hotel project. Limited warehouse conditions could still carry out material control without using excess material inventory which had an impact on minimizing the emergence of waste.

Abstract

The construction project is one of the jobs that demands the final result to align with the planning, necessitating a check on the performance obtained during the project to address any deviations from the initial plan. The Earned Value method is one of the techniques that can be used to assess project performance based on cost and time. The objective of implementing an evaluation with the Earned Value method is to understand the project's performance based on value variances and performance indexes and to identify solutions as early as possible if the project is experiencing delays. Calculations using the Earned Value method are based on budgeted cost of work scheduled (BCWS), cost for work performed (BCWP), and actual cost of work performed (ACWP). The research results on the Gunung Anyar apartment project reveal that the project experienced a delay of 3 weeks from the initial plan and a cost overrun of IDR 21,863,495,000 from the budget of IDR 19,533,411,725 (-12%). From the evaluation, it is evident that the Earned Value method needs to be applied during the ongoing project, especially when facing delays, to find solutions as early as possible to overcome the issues and prevent further significant losses.
