Analysis of Factors Contributing to Project Delays in Separate Contracts: A Case Research of Elevator Work in A 10-Story Office Building Construction Project

Abstract

Construction projects often face delays, which can significantly impact both time and cost. This research focuses on identifying the factors contributing to delays in elevator work within the context of a 10-story office building construction project in Gresik, Indonesia. The objective of this research is to assess the causes of delays in elevator work and evaluate their impact on the overall project schedule and budget. The research uses a quantitative approach, analyzing secondary data from project documentation, interviews with relevant parties, and comparative analysis. Findings indicate that elevator work delays resulted in a 91-day deviation from the planned schedule. These delays were primarily caused by technical issues, such as late design approvals and the need to modify construction methods, which led to increased costs. The research also emphasizes the domino effect of these delays on other project components, thereby underlining the importance of effective coordination and planning. The research concludes by offering strategic recommendations to mitigate similar delays in future projects, particularly when using separate contracting methods.
