Design the garage floor slab-on-grade, supported by the ground as shown in the attached image, in compliance with the SANS Code (South African Standards), considering factors such as soil bearing capacity, soil pressure, and subgrade modulus. If no soil investigation data is available, assume a G5 or G6 subbase for the soil. The garage floor may have a thickness of 125 mm with 193 mesh reinforcement. Additionally, design the strongroom as shown in the attached image according to the South African Code (SANS 953-2:2003). The strongroom will be a Category BC (brick and concrete construction) type, with walls made of brick outer and inner skins, reinforced by a concrete core. The ground-level floor shall be a 100 mm thick 15 MPa reinforced concrete slab. The walls will be 320 mm thick, composed of 110 mm thick 7 MPa masonry outer and inner skins, with a 100 mm thick 25 MPa reinforced concrete core. The roof will be 150 mm thick, with 25 MPa reinforced concrete. Fire resistance should also be incorporated into the strongroom design. The strongroom will have a Category 2 HD door, 50 mm thick, with a wall opening of 1950 x 940 mm, weighing 540 kg. Additionally, design the beam above the garage entrance as a standard beam in accordance with the SANS Code.
