Definition
Construction drawings are the set the project is actually built from: plans, sections, elevations and architectural, structural and MEP details with enough dimensions, levels and specifications for the contractor to work without guessing.
Why it matters on a project
Anything missing from them turns on site into an RFI, a variation or a defect. A complete set before award also makes contractor bids comparable.
Measurement and pricing
Usually priced per square metre of built-up area or as a lump sum, depending on disciplines and level of detail.
Common mistake
Starting work from the building-permit drawings alone, which do not carry enough detail to build from.
Frequently asked questions
What is the difference between permit drawings and construction drawings?
Permit drawings are enough for municipal approval and show the general layout and areas; construction drawings add the dimensions, levels, details and specifications needed to build.
Which disciplines do construction drawings cover?
Architecture, structure, electrical, HVAC, plumbing and fire protection, and sometimes landscape and interiors depending on the project.
