St. Thomas · St. Croix · St. John

Construction surveying for Virgin Islands jobsites.

Earthwork quantities, progress topo, 360° site records, and as-built models for active jobsites on St. Thomas, St. Croix, and St. John — delivered in the formats your project team already works in. Flown on NDAA-compliant aircraft, under a USVI-licensed surveyor of record.

Construction support

Four disciplines, one mobilization.

One mobilization to an active site produces the quantities, the basemap, the progress record, and the as-built model. One coordination call, one site visit, one set of data the whole project team works from — instead of four vendors flying over the same ground four times.

Why DSS

Compliant hardware.
Licensed deliverables.

Most of the capital moving through the Virgin Islands right now is federal. Federal money brings procurement rules with it — and a great deal of drone hardware on the market cannot legally be used on that work.

  • NDAA-compliant, Blue UAS aircraft. Eligible for federally funded and agency work without a waiver conversation.
  • USVI-licensed surveyor of record. Survey deliverables are reviewed and signed — not handed over as raw drone output.
  • Engineering input arranged on scope. Where a deliverable will be designed against rather than filed, professional engineering review is arranged as part of that scope.
  • FAA Part 107 with airspace coordination. Including the controlled airspace around Cyril E. King and Henry E. Rohlsen.
  • Locally staffed on St. Thomas. Aerial capture, scanning, processing, and site documentation run out of Red Hook, with no mainland mobilization behind them. Work that does mobilize a crew is scoped and scheduled as such, in the proposal.

Coverage

We work the whole territory.

Each island presents a different survey problem. We plan for the one in front of us.

Coverage across the U.S. Virgin Islands A schematic map of the territory. St. Thomas and St. John sit close together in the northern group, with Water Island just south of St. Thomas. St. Croix lies about forty miles further south and is reached as a separate mobilization. Dashed rings mark the controlled airspace around Cyril E. King on St. Thomas and Henry E. Rohlsen on St. Croix. St. Thomas St. John St. Croix TIST TISX Water Island about 40 miles N
Schematic, not to scale. The northern group works as a single mobilization; St. Croix is a separate one. Dashed rings mark the controlled airspace around Cyril E. King (TIST) and Henry E. Rohlsen (TISX), which is coordinated before a flight is scheduled rather than during it.

How it works

From first call to final file.

A fixed, repeatable sequence, so you always know what happens next and what it costs.

  1. Scope

    Send the site, the schedule, and what you need out of it. A short call fixes the site limits, the accuracy target, the deliverable formats and any airspace constraint, and a fixed-fee scope comes back within one business day.

  2. Control

    Ground control and check points set with GNSS or total station, tied to the coordinate system your project already uses. Accuracy is measured, not assumed.

  3. Capture

    Flight and scan executed in a single mobilization wherever the site allows — aerial, terrestrial, and 360° captured on the same visit. Coordinated around active work, not against it.

  4. Deliver

    Processed, verified against the check points, and reviewed by a person before anything is released. Handed off as the DWG, surface, point cloud, model or report your team asked for, with the accuracy report, typically within 48 hours. BIM runs on its own quoted schedule.

Where we fit

Most projects reconstruct their history after the fact.

From photos on somebody’s phone, from memory, and from a schedule that stopped matching the field weeks ago. The alternative is documenting the job as it happens.

/ The problem

What projects run into

  • Progress is reported, not shown. A dispute about what was complete on what date gets settled from memory.
  • Interior conditions disappear behind finishes. Nobody photographed the wall before it closed.
  • Quantities and as-builts get assembled at the end, under deadline, from incomplete field data.
  • Mainland crews mean lead time, mobilization cost, and a schedule that bends around travel.
/ The answer

Where DSS fits

  • A dated, measurable record. Georeferenced orthomosaics and point clouds you can measure against, flight over flight, at 0.10 ft.
  • The interior captured too. 360° walkthroughs pinned to the floor plan, so any date and any room is one click away.
  • Deliverables your team already uses. Civil 3D surfaces, Revit models, takeoff quantities, and scaled drawings — not a login to somebody’s portal.
  • Based in the territory. The aerial, scanning and documentation crews and their equipment are here, not flown in per visit. Where a job does mobilize a crew, we scope and price it as exactly that.

Tell us about the site.

Send the island, the parcel, and what you need out the other end. We’ll come back with a scoped, fixed-fee proposal within one business day.
