Currently, the development of knowledge in the field of civil engineering is very rapid. The development of knowledge in the field of civil engineering has given rise to many ways to facilitate work on multi-story building structures. This development has given rise to many ways to make work easier. One way is to use precast hollow core slabs as a substitute for conventional concrete slabs. The Hollow Core Slab precast system first uses a special holder for placing the prestressed cable which is then pulled or what is called a pretensioning system. The relationship that can be drawn between precast concrete and prestressed concrete is that many prestressed concrete constructions are precast concrete. One example of precast concrete is Hollow Core Slabs (HCS). Based on the results of structural analysis using software, the maximum deviation was 34.62 mm. The results of the re-planning obtained an HCS design using a height of 150 mm and a width of 1200 mm, using 6 strands with a diameter of 7/16 in with a quality of 270 ksi low relax strand. The inverted T-beam has dimensions of 300 mm wide and 500 mm high and the column has dimensions of 450 mm x 450 mm
