Reality capture for construction

Documenting a site is cheap. Reconstructing what a site looked like eight months ago from memory and a few phone photos is not. A recurring flight on the same plan gives you a record that holds up in a meeting or a claim.

01/The problem

The record you wish you had is the one nobody took.

Quantities get disputed. Schedules get argued. Somebody remembers the pad differently than somebody else. In almost every case the fix would have been a dated, measurable record of the site on the day in question, and almost nobody has one.

A monthly flight on a fixed plan produces exactly that, plus earthwork volumes you can defend and an as built comparison against the design surface. It costs a fraction of a single change order fight.

What you get from a progress flight

  • Dated orthomosaic on a repeatable flight plan
  • Earthwork cut and fill against your design surface
  • Stockpile volumes with the arithmetic shown
  • As built surface comparison
  • Colorized site model for coordination
  • Progress exhibits for owner and lender reporting
  • Existing conditions record before mobilization
  • Thermal on roofs and envelope where relevant
02/Fit

Where contractors use it

01

Before you mobilize

Pre construction existing conditions with a date on them. The cheapest insurance on any job that touches an adjacent property.

02

Monthly progress

Same flight plan, same altitude, same time of day. Comparable months instead of a folder of unrelated photos.

03

Earthwork and quantities

Volumes derived from a surface rather than argued from a spreadsheet, with the surface delivered so anyone can check it.

04

Closeout and turnover

An as built record handed to the owner, which is increasingly what owners are asking for anyway.

03/Proof

Data from delivered work.

Photogrammetric model of a site under construction
Site model on a repeatable plan. Month over month comparisons stay honest.
Stockpile point cloud used for volume calculation
Volumes from the surface, not from a tape and an assumption.
High resolution orthomosaic of paving and site work
Orthorectified site imagery. Measurable, dated, and easy to hand to an owner.
04/Services

What we typically fly for this work.

05/Questions

Common questions.

How often should we fly an active site?
Monthly is the common rhythm and it lines up with pay applications. Sites moving a lot of dirt sometimes go every two weeks during earthwork and then drop back.
Can you fly while we are working?
Yes. We coordinate with the superintendent, stay clear of crane and lift operations, and plan around the day's activity.
Will the volumes hold up if they are challenged?
The surface comes with the volumes, so anyone can recompute them. That is a very different conversation than defending a number with no model behind it.
Do you work under the GC or directly for the owner?
Either. Owners increasingly want their own record, and GCs want the quantities. We have no problem with either arrangement as long as everyone knows who is receiving the data.
05/Next step

Start with one site.

Send the boundary and the deliverable you need. We scope it, fly it, and return the data in your format, typically in under seven days.
