General Abstract: Cost advice through estimating is one of the core competencies expected from a Quantity Surveyor as he/ she shall take professional liability for accuracy of that cost advice. The substructure cost of buildings and civil engineering works mostly depend on foreseeability of subsurface conditions, reliability of geological investigations, technology used, method of construction and Structural Engineering design concept. The shoring or earth retaining systems is a significant attribute of substructure cost, time and risks. Therefore, the knowledge in substructure construction and earth retaining systems, such as diaphragm walls, secant piling, micro piling etc., are key enablers to provide a reasonably accurate cost advice. IQSSL presents this CPD to enhance your knowledge in methods of shoring or earth retaining systems of basement constructions in Structural Engineering perspectives in terms of cost, time and risks involved.
