Construction of Jakarta Mass Rapid Transit Project (Phase 2) Contract Package 203 Underground Section-Civil 03 PT Hutama Karya

In every building construction, all structural components must have the strength to withstand the load they carry. Beams and columns are very important structural components in building construction; both structural components must be calculated and analyzed based on the appropriate combination of loads and factored forces. In compiling this research report, the author reviews the use of concrete columns in the Tangerang city sports field construction project. This review aims to determine how many pieces of reinforcement are used and how much concrete volume is needed for each column. From the results of the author's review, the column used in this project is the K1 column type with dimensions of 60x60 cm with 12D25 reinforcement, with a column height of 13 m, the volume per column is 4.68 m3, with a concrete volume per column of 4.6286 m3. So that the results obtained on 70 column pillars require a concrete volume of 324,002 m3, with a large mixer truck capacity of 7.5 m3, it requires 44 trucks to transport the ready mix concrete.
