High-quality RTK-enabled drone surveys to monitor construction progress, verify built works and produce auditable as-built records for civil engineering projects. We capture date-stamped site imagery and surface models and tie outputs to your project grid using site control and QA checkpoints, enabling clear comparisons against design and reliable reporting.
‍
Deliverables: date-stamped orthomosaics, 2D CAD as-built plans (where required), 3D terrain/surface models, contour maps and photo reports aligned to your site grid and project coordinate system.

Typical use cases

✔   Regular progress surveys for highways, energy projects and earthworks
✔   Checking levels, alignments and extents against design using overlaid data
✔   Measuring progress quantities for interim valuations and payment applications
✔   Recording exposed services and structures before backfilling (drainage, ducts, crossings)
✔   As-built surface models and plans to support handover, O&M manuals and asset records

Data we capture

✔   RTK-referenced ground and surface levels tied to your site grid using site control and QA checkpoints
✔   Built features – carriageway layers, kerbs, footways, platforms, attenuation ponds, chambers
✔   Linear features – drainage runs, ducts, cable routes, fence lines, barriers, batter toes and crests
✔   Control points and permanent benchmarks used to reference each survey campaign

Who is this service is for?

✔   Main contractors and client teams who need clear evidence of progress and as-built records
✔   Commercial managers and quantity surveyors preparing valuations and payment applications
✔   Site engineers and project managers who need accurate progress mapping for QA and reporting
✔   Designers and consultants who need as-built models and redline information to update design
✔   Developers and asset owners who require reliable documentation of what has been built
