PAS 128 · RICS-aligned · CAA-approved drone operations

We measure the ground
so nothing gets built on a guess.

LiDAR, GNSS, topographical, utility (GPR) and drone survey services for engineers, architects and contractors who need data they can design against — not just a drawing that looks right.

Survey methods

Five ways to capture the truth on site

Every project gets the capture method that fits the brief — often more than one, combined into a single coordinated dataset.

METHOD / 01

LiDAR scanning

Static terrestrial and mobile LiDAR capture producing dense, registered point clouds for as-built surveys, clash detection and BIM-ready models.

Point cloud±3–5mmLAS / LAZ / E57
METHOD / 02

GNSS surveys

RTK and network-corrected GNSS positioning tied to OS National Grid or project datum, for control networks, topographic detail and boundary work.

RTK / VRSControl networksOSGB36 & ETRS89
METHOD / 03

Topographical surveys

Detailed ground-level and detail surveys — levels, features, boundaries and vegetation — plotted to the accuracy your design team can build on.

LevelsSite plansDWG / DXF
METHOD / 04

Utility surveys (GPR)

PAS 128-compliant detection and mapping of buried utilities using ground-penetrating radar and electromagnetic locating, before you break ground.

METHOD / 05

Drone surveys

Aerial photogrammetry and orthomosaic mapping for volumetric surveys, stockpile monitoring, and topography across large or difficult-access sites.

Tell us the site, we'll tell you the method

Most briefs combine two or three capture methods into one dataset. Send us the location and what the design team needs, and we'll scope it.

How a survey runs

From enquiry to deliverable, in five stages

The same coordinated workflow whether it's a single boundary or a multi-hectare site.

STAGE 01

Brief & desk study

We review existing records, drawings and utility plans before anyone sets foot on site.

STAGE 02

Site reconnaissance

Access, control points and capture method are confirmed against the real conditions on the ground.

STAGE 03

Data capture

LiDAR, GNSS, GPR and drone capture, tied to a common control network and datum.

STAGE 04

Processing & QA

Point clouds registered, data classified, and every dataset checked against control before it leaves the office.

STAGE 05

Deliverable

Drawings, models or point clouds handed over in the format your design team actually works in.
