The basic phases of a construction project are predesign, design, construction and closeout. A more detailed list sometimes includes schematic design, design development, creation of construction documents and the bidding process.
Every construction project begins with planning, which starts with an idea to solve a problem. Planners identify the scope, or architectural program and infrastructure requirements, of a potential project in the predesign phase. They also evaluate the feasibility of the project.
Next, planners design the schematics of the construction project, which requires defining the size of spaces, the budget, and the building's style and access. Planners also work on the structural, electrical and mechanical schematics of the project. Design development is a continuation of schematic design. Planners further refine spaces, schematics and configurations. They also decide on materials and create a detailed image of the final project.
Next, planners create specifications for the project and check building codes. Specifications include the manufacturer and quality of the materials and tools used in the project. Once this is finished the project is put up for bidding.
Upon accepting a bid construction begins, and the winning bidder builds the structure according to the specifications. Once construction is completed the project enters the closeout phase, during which time the facility is turned over to the client.
