Construction Law covers all legal issues regarding the construction process from acquiring land and financing a project to post-construction dispute resolution. These matters include a wide scope of matters, such as building contracts, construction and builders' liens, bonds and sureties, tendering, and construction claims, which pertain to all parties in the construction industry, including architects, subcontractors, general contractors, material suppliers, builders, designers, developers, planners, engineers and financial institutions.

Construction law may embody improvements of all sizes and complexity from basic, residential work, to enormous, complex projects of hydroelectric impoundment and generation, city planning, and mass transportation. While construction law cuts across a broad spectrum of laws, it is still closely interrelated with many of the traditionally recognized principals and doctrines of the law, including: real property, contracts, torts, business organizations, labor, tax, and (possible) conflicts of laws.

Contract terms and definitions in construction contracts are very important, because they eliminate ambiguity and misunderstanding; they also govern the specific understanding and agreement of the parties to the contract, and provide the framework for interpretation and resolution of construct contract claims under the laws of each state.
