Abstract

Construction project control is a systematic process aimed at ensuring that project objectives align with planning standards. One method used to accelerate project duration is "crashing," which involves reducing the time of specific activities that affect project completion, focusing particularly on activities on the critical path. This research adopts a descriptive method to collect and analyze data on the status of current symptoms related to project time management. Data collection was conducted through documentation, utilizing records, images, and work outputs. The results show that total project costs decrease significantly as the level of time compression (reduction of project duration) increases. However, increasing labor costs exhibits a small but consistent rise, indicating lower cost efficiency. The most optimal project costs were observed when additional working time was utilized, as opposed to adding more labor. In conclusion, while the crashing method is effective for reducing the risk of fines and indirect costs, selecting the best alternative requires balancing productivity and marginal costs (cost-time trade-off). For similar projects, extending working hours proves more cost-effective than increasing workforce size.

Abstract

The development of educational infrastructure is a crucial aspect in supporting the improvement of the quality of learning and human resource development in Indonesia. However, in its implementation, construction projects often face challenges in the form of delays in completion and cost inefficiencies, which impact the disruption of the educational process and increase the budget. This study aims to analyze the cost efficiency and acceleration of the implementation time of the Sunan Ampel Jombang Junior High School construction project through the crashing method approach, which is a technique in project management used to accelerate project completion time by selectively adding resources to critical activities. The delay in the start of a project is the main problem faced by the implementers of the Sunan Ampel Jombang Junior High School construction project, resulting in delays in final completion and an inflated project value. Based on the analysis conducted, this study also provides solutions to overcome this. The results of the analysis of the Sunan Ampel Jombang Junior High School construction project show an additional cost of Rp. 163,845,745.00 from the normal work cost to Rp. 2,623,114,845.00, an increase of 0.93%. This research provides practical contributions for project managers and contractors in making strategic decisions related to controlling project time and costs and can be a reference in managing the risk of project delays in the future.
