Construction Documents
Construction documents (CDs) are the complete, legally binding set of drawings and written specifications that define every aspect of a construction project in enough detail for contractors to build and obtain permits. CDs are produced by the architect after design is finalized and represent the final, buildable version of the project.

Key Facts
- 1Construction documents for a commercial tenant improvement typically take 4–8 weeks to produce and cost $8,000–$30,000+ depending on project complexity
- 2CDs must be stamped by a licensed architect or engineer in most U.S. jurisdictions before they can be submitted for a building permit
- 3Incomplete or poorly coordinated CDs are the single largest driver of field change orders — each gap in the documents becomes a contractor decision made without owner input
What Construction Documents Include
- Architectural drawings: floor plans, reflected ceiling plans, elevations, sections, and details
- Structural drawings: framing plans and connection details (if structural work is required)
- MEP drawings: plumbing plans, electrical plans, HVAC plans, and equipment schedules
- Specifications: written requirements for materials, workmanship standards, and testing
- Finish schedule: what materials go where throughout the space
- Door and hardware schedule: door types, sizes, hardware sets, and fire ratings
- Equipment schedule: dimensions, utility connections, and clearances for all major equipment
Schematic Design vs. Design Development vs. Construction Documents
Architects typically work in phases: Schematic Design (SD) establishes the overall concept and layout; Design Development (DD) refines decisions on systems, materials, and details; Construction Documents produce the final buildable set. Each phase builds on the last and involves owner review and approval.
Many tenants skip to CDs too quickly, bypassing adequate SD and DD review. This leads to CDs that don't fully reflect the owner's intent — then expensive change orders when field conditions reveal the gap.
Frequently Asked Questions
Do I need construction documents for a small commercial buildout?
In most jurisdictions, yes — any commercial buildout requiring a building permit needs architect-stamped CDs. Even 'simple' projects like retail fit-outs require electrical, plumbing, and occupancy compliance documentation that must be reviewed by the building department.
What's the difference between permit drawings and construction documents?
Permit drawings are a subset of CDs submitted to the building department for approval. Full CDs include everything the contractor needs to build — including specifications and details that may not be required by the building department but are essential for quality construction.
