This study aims to analyze the timeliness in the construction of a project. Time efficiency of project implementation is one of the efforts in optimizing the use of implementation time. CPM is a network method used to determine the critical path of each implementation. Schedule delays in construction projects are one of the problems that can harm various parties to the project. This method is taken by eliminating multitasking, student syndrome, parkinson's law and providing a buffer at the end of the project. This study uses a System Literature Review (SLR) approach which is used to identify and answer existing questions and the results are relevant. Project implementation wants to find a useful method to improve the quality of planning and control in the face of a complex number of activities. Then a network method was found that serves to provide systematic planning, scheduling, and control. With the PERT and CPM methods, the time scheduling of a project will be more regular, as well as the availability of human resources which greatly affect the success of the development of a project. This study aims to compare the Pert and CPM methods in carrying out the development of a project. Based on research using this method to prove that by using the PERT and CPM methods the development of a project will run optimally, effectively and efficiently. So that it can be used as a reference in project implementation performance.
