Who owns record drawings and as-built drawings?
By SourceX Editorial · Reviewed by Noah Loul ·
Short answer
As-built drawings are usually prepared by the contractor and delivered to the owner under the construction contract, so the owner controls them, not the architect. Record drawings differ: the architect compiles them from contractor information, and they are typically treated as the architect's instruments of service. As-builts prepared by others are usually not the firm's to license.
Key takeaways
- Contractor as-builts are a closeout deliverable to the owner, so the design firm's copies are archive copies, not licensable assets.
- Record drawings prepared by the architect are usually instruments of service, subject to the owner's license and confidentiality terms.
- Owner-furnished existing conditions drawings and surveys stay with the owner or their original authors.
- The firm's own closeout process records, such as transfer logs and site observation reports, are the realistic licensing candidates.
- Sort every closeout package by who prepared each document before any reuse or licensing decision.
Who owns as-built drawings?#
As-built drawings are usually owned or controlled by the project owner, because the contractor prepares them as a closeout deliverable required by the construction contract. The architect may review them or receive copies during construction administration, but the markups are the contractor's work, delivered to the owner.
Record drawings, when the architect prepares them, sit on the other side of the line. They are drawings produced by the design firm from information the contractor supplied, and standard owner-architect forms usually treat them like other instruments of service, subject to the license granted to the owner. AIA B101-2017 Section 7.2, for example, deems the architect the author and owner of its instruments of service, and AIA A201-2017 Section 1.5.1 says the contractor and its subcontractors and suppliers do not own or claim copyright in them. A contractor's markups on those drawings do not move the architect's copyright, and a negotiated contract can change the default, so the signed agreement decides.
Record drawings vs as-builts: what is the difference?#
Record drawings and as-builts differ in who prepares them and what they claim to show. As-builts are the contractor's marked-up drawings, updated during construction to show deviations, concealed utilities, field changes and final locations. Record drawings are a clean set the architect or engineer produces by transferring those markups onto the design documents.
The difference matters for liability as much as for ownership. A record drawing reflects information the design firm did not verify in the field, which is why firms commonly add a note that the set relies on contractor-provided information. Owners and contractors also use the two terms loosely, so read the contract to see which document was actually required and from whom.
Who prepares each closeout document, and who usually holds it?#
Closeout and existing-conditions documents should be sorted by who prepared them before anyone decides what the firm can reuse or license. The table shows the typical position; your contracts may differ.
| Document | Who prepares it | Typical holder | Firm's to license? |
|---|---|---|---|
| Contractor as-builts (field redlines) | General contractor and subcontractors | Owner, under the construction contract | No |
| Record drawings | Architect or engineer, from contractor information | Firm keeps copyright and the owner holds a license, unless the contract says otherwise | Possibly, after rights and confidentiality review |
| Owner-furnished existing conditions drawings | Prior architects, surveyors or the owner's staff | Owner, or the original author | No |
| Surveys and utility locates | Licensed surveyor or locating service | Owner or surveyor, per their agreement | No |
| Consultant record sets for structure and MEP | Engineering consultants | Consultant, subject to its agreement | Only the consultant can decide |
| Field verification notes and site observation reports | Architect's staff | Firm | Candidate, after removing client identifiers |
| Operation and maintenance manuals and warranties | Contractor and manufacturers | Owner | No |
What the owner-architect agreement adds#
The owner-architect agreement decides whether record drawings are a required service and who controls them once delivered. Some agreements list record drawings as an additional service, others fold them into closeout, and owner-written contracts may define them as owner property along with all electronic files.
Electronic file releases deserve attention. When owners ask for native CAD or Revit files at closeout, firms often require a release that limits reliance and further use. Keep those releases with the project record, since they also document what the owner received and on what terms.
- Is preparing record drawings a basic or an additional service?
- Does the ownership clause cover record drawings and electronic files?
- Is there a disclaimer on the accuracy of contractor-provided information?
- Does the owner receive native files, and under what release terms?
- Do confidentiality terms cover facility information or security details?
As-built drawings and liability#
As-built drawings carry liability questions because owners rely on them for years after the design firm has left the project. Renovation designers, facility managers and utility crews use them to decide where to cut, dig or connect, so an error can surface long after closeout.
Design firms manage that exposure by being precise about provenance: which entries came from contractor markups, which were field-verified by the firm and which were never checked. Packaging records for any outside use should keep the same distinction, so a reader can tell observed fact from reported fact. Questions about how a specific license might interact with professional liability coverage belong with your broker and counsel.
What part of closeout records is the firm's to license?#
The firm's own closeout records are the realistic candidates: the process of producing record drawings, not the contractor's information inside them. That includes transfer logs, discrepancy notes, punch lists the firm prepared, site observation reports and the correspondence that resolved field conditions.
These records also tend to be the most useful. A sequence showing a field change, the RFI that triggered it, the architect's response and the final record entry captures professional judgment. A clean record set on its own mostly captures geometry.
Remove client names, addresses and facility details that could reveal security arrangements, and exclude projects where confidentiality clauses forbid disclosure to third parties.
Illustrative: sorting a closeout archive#
Illustrative: Ridgeline Studio, a fictional architecture firm, stores closeout packages in Procore and on its own file server. Each package mixes contractor as-builts, the firm's record drawings, operation and maintenance manuals and the firm's construction administration logs.
When a principal asks what the firm actually controls, the team splits each package by preparer. Contractor as-builts and manuals are tagged as owner deliverables and left alone. Record drawings wait for a contract review. The firm's site observation reports, RFI responses and record-transfer logs, which tie each change to its source, become the candidate set.
The exercise also surfaces a gap: on several projects the firm never kept the contractor markups it transferred, so the link between field change and record entry is lost. New projects now save them with the record set.
How SourceX approaches record and as-built drawings#
In the SourceX five-step transaction, the Rights step separates documents the firm prepared from documents others prepared, using the owner agreement and construction administration records. Only the firm's own records move to Preparation, where client identifiers and sensitive facility details are removed. The SourceX Evidence Packet records which documents were included, who prepared them and the rights relied on, so contractor or owner material is not delivered by accident.
Large record sets and models stay in the firm's own storage until delivery is approved, and the initial fit check asks only for metadata, such as which systems hold closeout packages and how many years they cover.
Frequently asked questions
Can we keep copies of contractor as-builts in our archive?
Firms commonly keep copies for their professional records and for defending future claims, and contracts usually allow it. Keeping a copy for your files is different from using or disclosing it elsewhere, which remains the owner's decision under the construction contract.
Does the owner need our permission to give record drawings to a future architect?
Under standard forms, owners usually hold a license to use the architect's instruments of service for using, maintaining, altering and adding to the project, which typically covers sharing record drawings with a future architect working on that building. Check the license grant in your agreement for any limits or release requirements.
What if the contract says the owner owns all drawings?
Then record drawings are likely the owner's too, and the firm should treat them as client deliverables. The firm may still control internal records, such as its logs and observation reports, unless the contract defines project information broadly enough to include them.
Who owns a BIM model updated to as-built conditions?
A record model follows the same logic as drawings: who updated it, and under which contract. When the architect updates its own design model from contractor information, the model is usually an instrument of service. When the contractor or a facility management consultant builds it, it belongs with them or the owner.
Are record drawings reliable enough to use as training material?
They are as reliable as the contractor information behind them. That limitation is a reason to pair record drawings with the RFIs, field reports and transfer logs that explain each change, so any user can see where each entry came from and how it was checked.
Are as-builts for public buildings public records?
Drawings held by a public owner may be subject to public records laws, although many jurisdictions limit access to security-sensitive building information. Public availability does not transfer copyright and does not give a design firm the right to license a contractor's work.
