Reinforced poured concrete basement construction is a multiple step operation. The function of substructure is the transfer of loads from the superstructure to the underlying soil. Deep foundation solutions require piles to be sunk in to more stable ground beneath the structure. It provides stability to the structure as a whole. It is mainly used for masonry wall foundations. A finishing plate or mesh is attached to the bar ends to hold the slope face in place. In continuous footings, a footing is common for more than two columns in a row. A Pile foundation is a type of deep foundation comprising a long, slender column used to transfer the load from the superstructure to the lower-lying ground, providing overall support to the structure. Buildings and bridges are often the first structures to come to mind, because they are the most obvious engineering creations. Stairs and lifts, 9. A plinth beam helps to transfer and distribute the load evenly from the walls to the foundation. Pile foundations transfer the load through skin friction or end bearing mechanism. If contamination testing is specified a desk study of the site and its surrounding area should be undertaken, prior to the ground investigation, to help identify the past land usages of the site. More resistant to water because concrete has fewer and . The size and position of the strip foundation are dependent on the width of the wall. The settlement is uniform in this type of footing; hence, unnecessary stresses are not developed.
