Boundary wall layout were given in the Autocad 2D DWG drawing file. In this file raft footing sections were given. A raft foundation, also called a mat foundation, is essentially a continuous slab resting on the soil that extends over the entire footprint of the building, thereby supporting the building and transferring its weight to the ground. ... Stress is simply weight divided by area. In this boundary layout entry and exit line were mentioned. Depth, length, breath, dia of bar, number of bars and material used for the boundary wall were given in this drawing file. Thank you for the downloading the cad file and other cad program from our website.
