Every page of water conservancy and hydropower construction drawing design needs to be stamped with the special seal for engineering construction drawing design, the signature of four-level qualification examination and the seal of supervision. Theoretically, all new, rebuilt and expanded buildings need to be approved by national or local planning departments, design units and drawing review units, which is a formal process.

Construction management is the work of organizing, inspecting, coordinating and controlling all the construction processes of water conservancy projects. Its purpose is to ensure the quality and safety of the project according to the design requirements with the least manpower, material resources and funds, so that the project can be completed and put into production as scheduled or ahead of schedule and bring benefits into play.
