Abstract
The leading causes of work accidents on construction projects are related to the unique characteristics of the construction project, different work locations, openness, and weather conditions. The professionalism of the parties involved in implementing a construction project significantly affects a construction project's safety and success. A review of engineers' professionalism on the failure and accidents of construction projects took a case study on the Pier Head PCB 34 Toll Road Bekasi Cawang Kampung Melayu, which was carried out fast track. The method chosen was to carry out a literature study and a simple analysis of these incidents. A simple analysis shows that the failure and accidents of the construction project are caused by the deterioration of the already plastic steel material, which has a direct impact on the bracket's ability to withstand loads during casting. Such deterioration does not need to occur if the entire project cycle is carried out properly with the parties' professional handling.
