Abstract

Cost overrun is one of the problems that often occurs in the implementation of construction projects, which can have an impact on reducing project efficiency, productivity and profitability. This research aims to identify and analyze the main factors causing cost overruns on construction projects. The research methodology used includes questionnaire surveys and interviews with project stakeholders, such as contractors, consultants and project owners.  The research results show that the main factors causing cost overruns are design changes during project implementation, inaccurate cost estimates, fluctuations in material prices, less effective project management, and late payments by the project owner. In addition, external factors such as poor weather conditions and government policies regarding construction also contribute to increased costs.  This research suggests a proactive approach to project planning and control, including improving the quality of cost estimates, risk management, and effective communication between all parties involved. By understanding the factors that cause cost overruns, it is hoped that construction projects can be carried out more efficiently and in accordance with the planned budget.

Abstract

The development of road infrastructure is an important factor in supporting economic growth and community welfare. One of the key aspects of road construction is the accurate calculation of material requirements, which can help reduce construction costs and improve road quality. This study aims to evaluate the effectiveness of using basic mathematics in calculating road material needs. The research method used is descriptive-analytical with a quantitative approach, with samples taken from completed road projects in Indonesia over the last five years. Data was collected through documentation, interviews, and observations. The results show that the use of basic mathematics in calculating material requirements is highly effective and accurate, with 2 out of 3 projects analyzed showing calculations that closely match the actual material needs in the field. External factors such as soil conditions and design changes during the project can affect calculation accuracy. The study concludes that a good understanding of basic mathematics is essential for civil engineering professionals, and recommends enhancing basic mathematics education to support the efficiency of road construction projects in Indonesia.
