Construction Monitoring & As-Built Maps

High-accuracy RTK drone surveys to monitor construction progress, verify built works and produce auditable as-built records for civil engineering projects. We capture time-stamped surface levels and visible site features using RTK control and site calibration to your project grid.

Deliverables: time-stamped orthomosaic images, 2D CAD as-built plans, 3D terrain models, contour maps and photo reports aligned to your site grid and local control network.

Typical use cases

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

Data we capture

✔   RTK-controlled ground and surface levels tied to your site grid
✔   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 every survey campaign

Who 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
✔   Designers and consultants who need as-built models and redline drawings to update design
✔   Developers and asset owners who require reliable documentation of what has been built
