The loads used in the design of abutments include the reactions transferred from the superstructure to the bearing, horizontal earth pressures, live loads, and surcharge loads. Substructure. End walls should withstand the outward horizontal thrust due to arch action. The function of substructure is the transfer of loads from the superstructure to the underlying soil. Reinforced poured concrete basement construction is a multiple step operation. In order for a site to be developed a number of other groundwork activities may have to take place and other substructures may have to be constructed.On sloping sites retaining walls may have to be constructed to make a level development platform to enable the best usage of the site area to be achieved. The soil profile is investigated thoroughly by a geotechnical engineer and it is finalized before adding a suitable foundation in the building structure. The soil or rock is removed section by section, instead of continuously in the CFA piling process. d. It transfers the loads to subsoil at a shallow depth, close to the ground level. The substructure is the part of the building that is built below the ground level whereas superstructure is the part of the structure that is constructed above the ground level.
