Site layout planning considers four key aspects: safety of temporary facilities, safety zones, optimal placement of facilities, and use of constructed spaces. It involves identifying temporary facilities needed to support construction, determining their size and placement within site boundaries. Temporary facilities include warehouses, job offices, workshops, batch plants, cranes, access roads, and welfare facilities. The primary goals of effective site layout are safety, productivity, and smooth material and equipment flow. It can also involve dynamic reorganization of temporary facility locations over time. Placement of facilities is especially important for restricted sites, where constructed spaces may be used for storage if available early and sufficiently sized.
