Starting a Remodel
Request existing-condition drawings sized to the proposed design and permit needs. Link the scope to addition and remodel drafting.
As-Builts vs. Record Drawings: What Is the Difference?
"As-built" can mean a contractor's field markups, a final construction record, or a measured drawing of an older building. Those are not automatically interchangeable. The safest approach is to define the document by purpose, author, source information, and required accuracy.
As-Builts vs. Record Drawings at a Glance
| Document | Typical timing | Primary source | Common purpose |
|---|---|---|---|
| Contractor as-built markups | During construction | Field changes, measurements, redlines, RFIs, and approved changes | Preserve what changed from the issued drawings |
| Final record drawings | At project closeout | Design revisions plus contractor-provided as-built information | Create an organized owner record of the completed project |
| Existing-condition drawings | Before a remodel, addition, or planning effort | Field measurements, scans, photos, old plans, and observable conditions | Give the next design team a current building base |
| Certified as-built survey | As required during or after site work | Surveyed locations and elevations | Document site improvements, boundaries, grades, or compliance |
Project language controls. A homeowner using "as-built" to request a measured floor plan may be describing a different deliverable than a public owner requiring contractor closeout records.
How Formal Standards Draw the Line
The U.S. General Services Administration's P100 Facilities Standards distinguishes contractor redline as-built drawings from final record drawings. The redlines capture actual measurements, changes, and related field information. The final record drawings incorporate design changes and contractor-noted as-built conditions into an organized record set.
The federal Unified Facilities Guide Specification for Closeout Submittals defines as-built drawings as contractor-maintained markups showing actual conditions and deviations. It defines record drawings as the final compilation of the actual conditions reflected in those as-builts.
These public-sector examples do not impose one vocabulary on every residential project. They demonstrate why a contract should state who records changes, who prepares the final file, and whether the deliverable is a redline, CAD update, signed record drawing, or measured existing-condition set.
Where Residential Existing-Condition Drawings Fit
A homeowner planning a remodel usually needs a reliable picture of the house before proposed work begins. That may include floor plans, exterior elevations, roof information, selected sections, openings, stairs, fixtures, and visible structural clues. Apex treats this as an existing-condition drawing scope and defines the capture method before drafting.
The information can come from owner or contractor measurements, organized photos, a local field partner, a scan, old plans, or a combination. Old documents reduce setup time when they are legible, but critical geometry still needs verification. Concealed framing, wiring, plumbing, foundations, and other hidden conditions remain outside a visual measurement scope unless separately investigated.
Read the complete residential as-built guide for process and scope boundaries, then use the as-built measurement checklist to see what field capture requires.
Define the Deliverable With Five Questions
- What decision will the drawings support? Early layout, permit design, contractor pricing, fabrication, owner records, and legal documentation have different needs.
- Who supplies field information? Name the person or company responsible for measurements, scans, photos, and verification.
- Which sheets are included? Floor plans alone are not the same as plans, elevations, sections, roof, and site context.
- What file format is required? State whether the handoff is PDF, editable CAD, BIM, marked-up source sheets, or another format.
- What is not verified? List inaccessible areas, concealed conditions, owner-supplied dimensions, and survey or engineering exclusions.
Those questions are also the core of an apples-to-apples price comparison. The residential as-built cost guide explains how scope depth, capture responsibility, complexity, and file requirements drive fees.
A Practical Contract Description
A useful residential scope might say: "Prepare existing-condition floor plans and four exterior elevations from client-provided measurements, photographs, and available permit drawings. Deliver scaled PDF and editable CAD. Identify unverified or inaccessible areas. Exclude boundary survey, structural investigation, concealed systems, code certification, and professional seals unless added in writing."
A construction closeout scope would say something different. It might require the contractor to maintain redlines during work, record approved deviations, certify the markups, and submit final files using the owner's drawing standards. The Unified Facilities Guide Specification includes separate content, file, quality-control, and final-package requirements, another reminder that file rules belong in the requirement, not in an assumption.
Which Document Should You Request?
Closing Out Construction
Follow the contract. Preserve field redlines, approved changes, final consultant information, and the required record-file format.
Proving Site Location
Request the appropriate service from a licensed surveyor. Building plans do not establish certified boundaries or elevations.
For permit work, connect the existing base to a coordinated permit-ready plan set. For team handoffs, see how remote drafting works and what to send for an accurate quote.
As-Builts and Record Drawings FAQ
Are as-built drawings and record drawings the same thing?
The terms are often used loosely, but formal project standards may distinguish them. Contractor-marked as-builts typically record construction changes, while final record drawings may be prepared from those markups and other approved changes. Define the required deliverable in the contract.
What are existing-condition drawings?
Existing-condition drawings document the observable and measurable building that exists before a remodel, addition, or planning project. They are a design base, not automatically a certified construction record or land survey.
Who is responsible for construction as-builts?
Responsibility depends on the contract. Many construction specifications assign field markups and change records to the contractor, then require a final record set or CAD update at closeout. Read the project requirements rather than assuming.
Can old permit drawings serve as as-builts?
They are useful source documents but do not prove current conditions. Buildings can differ from approved plans or change later. Critical geometry and project-specific conditions should be verified under a defined capture scope.
Do as-built drawings replace a property survey?
No. Building drawings and boundary or topographic surveys establish different facts. A licensed land surveyor should provide certified property, boundary, elevation, or site-location information when required.
