Construction documents are the final set of drawings and specifications used to build a project. They translate the design into precise instructions: dimensions, materials, assemblies, finishes, and performance requirements. Contractors bid from them and build from them. Lawyers argue over them when things go wrong.

The set typically includes architectural, structural, mechanical, electrical, and plumbing drawings, plus a written specification book. Drawings show where things go. Specifications describe what they are and how they must perform. Together they define the scope of work.

Quality matters. Incomplete or contradictory documents lead to change orders, delays, and disputes. Good construction documents are coordinated: the architect's drawings match the engineer's, the specifications match the drawings, and the details actually work.

Technology has changed the format. Many projects now use BIM to generate construction documents, and some are built directly from models. But the purpose remains the same: give the contractor enough information to build it right.
