Room capacity improvement for classrooms at Bali State Polytechnic
Bali State Polytechnic is one of the vocational universities in Indonesia. Located in South Kuta District, Badung Regency, Bali, the Bali State Polytechnic is an attraction for high school/vocational school graduates from within and outside the region to receive education here. The increase in interest from prospective students is not in line with the addition of classroom facilities. The Bali State Polytechnic requires the addition of classrooms above 50 rooms, but to build a new building, the area used is no longer there. Therefore, one of the steps to add a classroom is to add a building floor to the exterior building. For this reason, it is necessary to conduct a study in terms of structural strength and financing for the addition of the floor. The structural study used is to conduct a hammer test and check the size of the foundation. The results of this study, by conducting a study on the strength of the structure, can be recommended to add floors, but with the reinforcement of the column foundation and the addition of columns on the 2nd floor. With the addition of the floor, the required cost is IDR 8,871,123,281 excluding tax
