location of buildings which will be constructed, arrangement of material and technical basis in order to serve construction process and human life within the boundaries of construction site Construction site layout is a very important content indispensable in the “construction organization design” and “construction management plan” files General concept of construction site layout design includes the following issues: + Determine specific location of buildings planned on the land granted to construct + Locate cranes, main equipment, and plants for construction + Design transportation system on the site + Design storage areas on the site + Design auxiliary workshops + Design temporary facilities on the site + Design temporary technical network on the site (electricity, water supply and drainage…) + Design systems of safety, security, and site cleaning Principles to design construction logistics: + Construction site layout must be designed so that temporary technical and material basis provide the best services for construction process, not affect technology, quality, construction duration, labour safety and environmental sanitation + Reduce the cost of constructing temporary
