As-Built Drawing Requirements: What Goes in a Complete As-Built Package

John Dutton

As-built drawings are typically required by contract, but many contractors don't know exactly what format is expected, what level of detail is needed, or how to produce a package that satisfies the owner and closes the permit. This guide covers what goes into a complete as-built package in 2026.

What format should as-built drawings be in?

The required format depends on the contract and the owner's needs. Common formats:

  • Marked-up paper drawings — the traditional approach. Red-lined copies of the original drawings with field changes noted by hand. Still acceptable on many projects, but harder to store, share, and use long-term.
  • Updated CAD files — the design team's CAD drawings updated to reflect field conditions. More useful for future work but requires the design team's involvement and adds cost.
  • PDF with markups — digital version of the marked-up drawing approach. Easier to share and store.
  • 3D model — increasingly common, especially for MEP-heavy projects. A spatial record of the space as built that allows remote measurement and coordination.
  • Photo documentation package — GPS-tagged, timestamped photos organised by project, often with a PDF report. Practical for most residential and light commercial work.

If the contract specifies a format, follow it. If not, a combination of photo documentation and PDF report is the minimum viable as-built for most projects.

What information must be included?

A complete as-built package for a typical commercial project includes:

Architectural

  • Final room dimensions (length, width, ceiling height)
  • Door and window opening sizes and locations as installed
  • Any partition changes from original design
  • Finish materials as installed (including substitutions)

Structural

  • Any structural member changes from design (relocated beams, added columns, modified connections)
  • Foundation modifications
  • Embedment and anchor locations

Mechanical

  • HVAC equipment locations as installed
  • Ductwork routing as installed (this almost always differs from design)
  • Equipment model numbers and capacities as installed
  • Control system wiring and device locations

Electrical

  • Panel locations and completed panel schedules
  • Conduit routing as installed
  • Device locations (outlets, switches, fixtures) with circuit assignments
  • Emergency system device locations

Plumbing

  • Pipe routing as installed (supply and drain)
  • Fixture locations and specifications as installed
  • Valve locations — especially shut-offs, which facility managers need most
  • Water heater and equipment locations

What about residential projects?

For residential renovation and new construction, the as-built requirements are often less formal but equally important. The minimum useful as-built for a residential project:

  • GPS-tagged photos of all rough-in before closing
  • Final room dimensions
  • Equipment model numbers and locations
  • Panel schedule

A PDF report from Manifold containing all project photos with GPS data and timestamps satisfies this requirement for most residential work.

Using Orbit Measure for as-built documentation

Manifold's Orbit Measure feature captures spatial as-built data from any iOS or Android phone. Walk a space for 60 seconds, upload the video, receive a measurable 3D model. You can take measurements between any two points in the model remotely — useful for verifying dimensions for the as-built package without returning to site.

The 3D model can be shared as a browser link — engineers, architects, and facility managers can view and measure from their desks without installing anything.

As-built documentation costs

Traditional as-built production (survey crew, CAD drafter) runs $500–5,000+ per project. Phone-based documentation through Manifold costs $24/user/month on the Photo+Scan plan — no per-project fees, no seat minimums.
