01
Retrace the baseline.
The closeout visit works from the baseline's own index: every room, elevation, and defect callout becomes a position to re-shoot. Nothing is left to judgment on site.
Post-construction surveys, New York
The after,
shot to match
the before.
A post construction survey re-documents every position from the pre-construction baseline after the work wraps. Same rooms, same elevations, same frames. Set side by side, the two records answer the only question a damage claim ever asks: did this exist before the project.
Section 01Why the second pass matters
A baseline without a closeout is half a defense.
Before proves prior.
After proves nothing new.
After proves nothing new.
What the baseline can prove.
The pre construction survey establishes what already existed. A crack documented before excavation predates the project, and no argument moves it. That half of the defense is airtight on its own.
What only the closeout can prove.
That nothing new appeared. A claim filed months after demobilization says the damage happened during your project. Without an end-state record, you're comparing a photograph against a memory. With one, you're comparing two dated photographs of the same wall.
Claims rarely arrive while the crew is still on site. They arrive after the fence comes down, when a neighbor notices something, or when a building changes hands and a new owner inspects closely for the first time. The closeout survey is what makes that late claim a lookup instead of a lawsuit.
Section 02How the comparison works
Retrace, re-shoot, set side by side.
Same frames.
New dates.
New dates.
02
Match the frames.
Each capture repeats the original angle and coverage, geotagged and timestamped like the first pass. Where the baseline flagged an existing defect, the closeout shot of the same spot is deliberate and close.
03
Deliver the pair.
The comparison report presents before and after together, organized by property and room, with both archives kept on file past closeout. A late claim gets answered with a page number.
Section 03What gets re-documented
Everything the baseline touched, inside and out.
Interiors. Exteriors.
Shared surfaces.

Closeout documentation
Closeout captures, shot to match the baseline.
Retainage releases faster when the end state is on file.
The closeout pass is also the natural moment to document the finished work itself. Owners often add interior and exterior photography of the completed project on the same visit, and for long builds the months between baseline and closeout are covered by construction progress photography, so the project file reads as one continuous, dated record. The report format matches our pre construction survey sample report structure end to end.

What is a post construction survey?
The closeout documentation pass. After the work wraps, the same rooms, elevations, and surfaces recorded in the pre-construction baseline are photographed again, from the same positions, so the two records show exactly what changed during the project and what didn't.
When should it happen?
At substantial completion, before demobilization if possible. Late enough that the work that could affect neighbors is finished, early enough that the record closes out the project file while access is still simple to arrange.
Do you need to have shot the original baseline?
No. The comparison is cleanest when we shot both ends, since the closeout pass retraces our own capture positions. If another firm produced the baseline, we match its coverage as closely as the record allows and document the differences in method.
What does the closeout report include?
High-resolution photographs of the same interior and exterior positions as the baseline, geotagged and timestamped, with condition notes. Where the baseline recorded an existing defect, the closeout image of the same spot sits beside it, so any claimed change is verifiable in one look.
Who orders one?
The same parties that order the baseline: general contractors closing out a project, developers and owners protecting against late claims, and insurers or counsel who want the documented end state on file before releasing retainage or closing a claim window.
Does it cover the neighbors or the site?
Primarily the adjacent properties the baseline covered, since that's where damage claims come from. The construction site itself can be included in the same closeout visit, which many owners want for the record of the finished work.
What if a neighbor claims damage after closeout?
The paired records answer it. The baseline shows the condition before work, the closeout shows it after, and both carry capture dates in the image data. If the crack is in the baseline, it predates the project. If it's in neither record, it postdates closeout. The archive stays on file for exactly this moment.
How long does the closeout pass take?
Usually the same footprint as the baseline: about a day or less per adjacent property depending on size and access, with the compiled comparison report following within days.
Is this required by NYC code?
The code requirement in NYC Building Code Section 3309.4.3 attaches to the pre-construction side. The closeout survey is the half that makes the baseline useful: without an end-state record, the baseline can prove a defect predates the project but not that the project caused nothing new. Most teams that invest in the baseline close the loop.
How much does it cost?
Quoted per project, based on the number of properties, their size, and access, and typically scoped alongside the baseline so the pair is priced as one documentation cycle. Send the project details through the form and we return a quote, usually within two business hours.
Section 05Scope both ends at once
The pair costs less scoped together than ordered apart.
One documentation cycle.
Two dated records.
Two dated records.
If your project hasn't broken ground yet, the efficient move is to scope the baseline and the closeout as one engagement. The capture plan gets built once, the positions carry over, and the comparison report is guaranteed to match frame for frame.
