Abstract

Proper planning for a construction project is a vital thing that supports the success of the project. Success in a construction project can be seen from the timeliness and costs that have been determined and planned. During the construction implementation process, delays often occur resulting in temporary stops in a construction project. Therefore, control is needed to overcome deviations that occur, one of which is through the Earned Value Analysis method. The aim of this research is to control the project and identify performance, cost and time indicators in more detail through in-depth analysis. Research on this multi-storey building project occurred under budget in the 1st week to the 37th week because CPI > 1 and over budget occurred in the 38th to 44th week because the CPI < 1. Meanwhile, in the 18th week to the 37th week there was a project delay because the SPI < 1. Based on estimates, there will be an additional cost of 12.80% and an additional time of 4 days. Therefore, there is a need for a solution to overcome time delays or reduce cost overruns.

Abstract

The construction of hospital infrastructure requires precise construction techniques, especially in areas with complex soil conditions. This study aims to analyze the implementation method of retaining walls in the basement of the RSPON project in Cawang, Jakarta. The study was conducted using a descriptive-analytical approach through field observations, documentation, and literature review. The main focus of the research is to identify the construction stages, types of materials, and techniques used in the construction of retaining walls. The results show that the selection of construction methods is adjusted to local geological characteristics, structural loads, and land stability requirements. The applied method provides an effective solution in overcoming technical challenges at the project site, considering safety, efficiency, and construction quality aspects. This research is expected to contribute to the development of retaining wall construction techniques for similar infrastructure projects, especially in areas with complex soil conditions.
