Specifications are essential documents in construction and engineering projects, providing comprehensive details about the materials, workmanship, quality, and standards required for a project. They often contain specific requirements that are not fully illustrated in the plans, such as the types of materials to use, performance criteria, and industry standards that must be adhered to.

The detail provided in specifications is generally much greater than that found in the plans.
