What construction documents are for

A documentation package typically includes:

• Drawings: plans, elevations, sections, details, schedules — the where and how big.

• Specifications: written requirements for materials, workmanship, standards and testing — the what quality.

• Schedules: doors, windows, finishes, hardware, equipment — structured lists.

• Reports and calculations from consultants (structural, services, fire, acoustic) where required.

Drawings and specifications work together; neither repeats everything the other says.

Authorities and certifiers check compliance for approvals. Estimators and contractors price the work. Builders and trades set out and build from them. Clients rely on them to get what they paid for. Each reads differently — the set must be complete, consistent and easy to navigate for all of them.

In most contracts the drawings and specification define the scope. Ambiguity or contradiction causes variations (extra cost), delays and disputes. Many contracts include an order of precedence clause saying which document governs when they conflict — but the goal is not to rely on it.

Concept and developed design documents communicate intent; approval documents show compliance; tender documents allow accurate pricing; construction documents are complete for building; as-built or record documents show what was actually built. Each issue has a stated purpose (status) on the title block.
