Changes in the implementation of concrete in situ work method to a precast method
Abstract
Sulfur Jetty Development Project and TUKS Oil and Gas Dredging Project The Balikpapan RDMP RU V Project is located in Balikpapan City, East Kalimantan. In this project there are 2 (two) main work scopes, namely sulfur jetty work and dredging work. Like other projects, an engineering review of the design drawings, work volumes, work methods, and work schedules is also carried out. The purpose of this engineering review is to evaluate whether the change in the method of implementation of concrete works in Situ to Precast can maximize the work in accordance with the concepts of quality, time and cost. For this reason the submission of the amendment to PERTAMINAwas accompanied by several technical reasons that affected the work. For the method change, a number of processes were carried out such as the submission of design changes, changes in work methods, the process of calculating the structure and several other matters related to the quality of the structure due to changes in the method of implementation. From the results of the calculation of the structure has adjusted to the needs in accordance with the initial plan, by changing the installation method but still maintaining the strength of the structure in accordance with the initial plan. With this Precast method, the construction process is relatively safer and measurable in terms of cost and time.
