As-Built Drawing Services

From Existing Structures to ew Builds-As-Built Drawings Done Right

What is

As-built Drawing?

As-built drawings answer one important question: what was actually built? Things change on a construction site—a pipe gets rerouted, a wall shifts slightly, an opening gets added. As-built drawings update the original plans to reflect every one of those real-world changes, creating an accurate permanent record of the finished structure.

  • Accurate Records
  • Facility Management
  • Renovation Support
  • Legal Compliance

What it includes

  • All field changes marked and updated in CAD
  • Actual dimensions, material changes, and final positions
  • Revised MEP routes, structural adjustments, and layout shifts

Why it matters

Years from now, when someone needs to renovate, repair, or insure this building these drawings are the only reliable record of what's actually inside the walls and under the floors.

Real example

A hospital is planning a renovation. Before anyone opens a wall, the team pulls the as-built drawings to find exactly where the electrical conduits and water pipes are running—avoiding a potentially dangerous and costly mistake.

The Basics

When Are As-Built Drawings Required?

  • ✓At construction project closeout for permit sign-off
  • ✓Before building sale or property transfer
  • ✓During renovation or tenant improvement planning
  • ✓For facility management and ongoing maintenance
  • ✓When applying for change-of-use or occupancy permits
  • ✓For insurance documentation and risk assessment
  • ✓When updating a building to current code compliance

Why It Matters

Why Building Owners Can't Afford to Skip As-Builts

Accurate as-built documentation protects your investment, reduces renovation risk, and keeps operations running smoothly for decades.

PC

Permit & Code Compliance

Most jurisdictions require as-built drawings as part of construction closeout before issuing a Certificate of Occupancy. Without them, your permit stays open indefinitely, blocking your CO, your mortgage, and your tenants.

RT

Renovation & Tenant Improvement

When you're ready to renovate or fit out a tenant space, your architect needs to know where every wall, duct, pipe, and conduit actually runs. Without as-builts, you're guessing and rework costs rise quickly.

FM

Facility Management

Facility managers rely on as-built drawings every day to locate shutoffs, plan preventive maintenance, manage equipment replacements, and coordinate service vendors with fewer delays.

PV

Property Value & Financing

Lenders, investors, and buyers frequently require as-built drawings during due diligence. Incomplete documentation can delay closings and trigger value reductions on commercial deals.

ER

Emergency Response

In a plumbing emergency, gas leak, or fire event, first responders and maintenance teams need exact utility and system locations. Inaccurate drawings can cost lives and millions in property damage.

IR

Insurance & Risk Documentation

Insurers increasingly require current as-built documentation for commercial property policies. Accurate records establish pre-loss building conditions and support claim validation.

Client Reviews

What Our Clients Say About Us

We sent DraftingBuddies a stack of contractor redlines from a 40,000 sq ft office renovation. They came back with a complete, organized CAD set in 5 days. Clean layers, correct dimensions, everything. Will absolutely use them again.

Our hospital needed as-built MEP drawings for a wing built in the 1990s - no digital files existed anywhere. DraftingBuddies coordinated with our facilities team, did the field verification work, and delivered a complete Revit model. Incredible service.

We're a GC and we outsource all our as-built drafting to DraftingBuddies. Faster than hiring in-house, always AIA-compliant, and they understand permit submission requirements. Highly recommend for any construction team needing closeout docs.

FAQs:

You Ask, We Draft

As-built drawings answer one important question: what was actually built? They update the original construction plans to reflect every real-world change made on site - rerouted pipes, shifted walls, added openings - creating an accurate permanent record of the finished structure for closeout, renovation, and facility management.
