Specifications are detailed descriptions of the materials, components, and workmanship that are required for a construction project. These descriptions usually include information about the size, quality, and type of materials that will be used, as well as any requirements for installation or assembly. Specifications are used to ensure that the finished product meets the required standards and will function as intended. They also provide a detailed outline of the work that will be required to complete the project, and are an important tool for bidding, cost estimating and construction management.
