Construction management or construction project management (CPM) is the overall planning, coordination, and control of a project from beginning to completion. CPM is aimed at meeting a client’s requirement in order to produce a functionally and financially viable project. CPM is project management that applies to the construction sector. The construction industry is composed of five sectors: residential, commercial, heavy civil, industrial, and environmental. A construction manager holds the same responsibilities and completes the same processes in each sector. All that separates a construction manager in one sector from one in another is the knowledge of the construction site. This may include different types of equipment, materials, subcontractors, and possibly locations. A contractor is assigned to a construction project once the design has been completed by the architect or is still in progress. This is done by going through a bidding process with different contractors. The contractor is selected by using one of the three selection methods: low-bid selection, best-value selection, or qualifications-based selection. A construction manager should have the ability to handle public safety, time management, decision making, mathematics, and human resources.
