Everything you build starts from a measurement.

Detail and levels across open ground, from a half-hectare infill plot to a forty-hectare coastal realignment. Delivered as a survey-grade DWG with a separate levelled surface, not a flat drawing with spot heights typed on.

Plans, sections and elevations of what is actually standing, including the parts that are out of plumb. Historic fabric is scanned before it is drawn, so the drawing can be checked against the cloud rather than against memory.

Registered point clouds for retrofit, clash detection and record. We publish the registration report with the cloud, so you can see the residual on every setup instead of taking the alignment on trust.

Single-beam and multibeam work in the estuaries and harbours along this coast, tied to the same datum as the land survey so the two halves of a sea wall meet in the middle. Tidal reduction from our own gauge, not an assumed curve.

Aerial capture where ground access is slow, unsafe or would take a week — quarry faces, roofs, forestry tracks, active earthworks. Always flown against ground control, because a flight without it is a picture, not a survey.

Control networks, setting out to the design model, and the as-built check that proves what went in. We keep the network adjusted for the life of the job, so month eleven is measured from the same points as week one.

Movement watched over months on retaining structures, quay walls and buildings next to deep excavation, with agreed trigger levels and a named person who phones when one is crossed rather than emailing a spreadsheet.

Electromagnetic and GPR detection of what is already under the site, surveyed in and stated at a quality level you can plan around. A drawing that quietly mixes QL-B and QL-D is worse than no drawing.
