Abstract

Each project has different standards according to the function and purpose of each building. There are several main components found in the building structure such as columns, beams, and slabs. Columns are vertical compression members that carry the weight of the entire building. Beams serve as a binder for columns and seats for the upper floor and roof. To make the desired shape of the column, beam or slab, formwork is needed which aims to be a concrete mold so that columns, beams and slabs can be formed according to the desired shape and design. Because formwork is a very important component of a building structure, a good formwork strength analysis is required. Each project has different reinforced concrete specifications according to the design that has been made. The specifications of a concrete can be fulfilled if it fulfills various requirements, to fulfill the requirements, before casting can be carried out a temperature test and a slump test. At each casting, before pouring the concrete it is very important to test the concrete so that it can monitor whether the concrete is of good quality and according to specifications. This is one of the methods of work carried out on the Upper West project in order to produce a building with good quality and on time. In the Upper West project there are also prestress beams that use a different quality of concrete from the other beams, namely FC 45 screening concrete. After casting, the prestress beams will also be subjected to a stress test and concrete compression test to determine their feasibility. An obstacle in the project needs to cause delays in existing progress, therefore it is necessary to prepare a catch up plan to overcome existing obstacles and minimize delays so that the project can still be completed on time without causing harm to the owner or the contractor himself.
