Topographical, Land, Engineering & Laser Scanning Surveys
A topographical survey is a detailed measured plan showing all physical features, levels, boundaries, structures, utilities and ground details on a site. It provides an accurate base for architects, planners, engineers and developers.
Laser scanning (3D scanning) uses high‑precision LiDAR technology to capture millions of measurement points and create a high‑accuracy 3D model of buildings, structures or environments.
It is ideal for:
Measured building surveys
Heritage sites
Complex structures
As‑built verification
Clash detection and BIM modelling
Laser scanning is recommended when:
You need high‑detail internal or external measurements
The structure is complex or irregular
You require 3D models, point clouds or BIM‑ready data
You need accurate as‑built information for construction or refurbishment
You want minimal disruption — scanning is fast and non‑intrusive
Traditional surveying is still ideal for open land, boundaries, utilities and engineering control.
Typical outputs include:
Point clouds (E57, LAS, PLY)
3D mesh models
Revit‑ready BIM models
2D plans, elevations and sections
High‑resolution panoramic images
Digital twins (on request)
Laser scanning typically achieves:
Sub‑centimetre accuracy for most structures
2–5mm accuracy for engineering‑grade scans
Accuracy depends on site conditions, access and required specification.
Timelines vary by complexity:
Small residential property: 1–3 hours
Medium commercial building: ½–1 day
Large industrial sites: 1–3 days
Processing and modelling usually take 3–10 working days depending on deliverables.
Yes — for internal laser scanning or measured building surveys, we require access to all relevant rooms, floors and areas.
For external scanning only, internal access is not required.
Simply contact us with:
Site address
Purpose of the survey
Any existing drawings
Required deliverables
We will confirm availability and provide a quotation
We use professional-grade scanners such as:
Leica RTC360 / BLK360
Trimble X7
FARO Focus
These produce high‑density point clouds and accurate 3D models suitable for engineering and architectural workflows.
No — laser scanning captures visible surfaces only.
For underground utilities, we use:
GPR (Ground Penetrating Radar)
EML (Electromagnetic Locators)
Drainage tracing tools
We can combine laser scanning + utility mapping for full above‑ and below‑ground datasets.
A topo survey typically includes:
Ground levels and contours
Buildings and structures
Boundaries, fences and walls
Roads, kerbs, footpaths
Trees and vegetation
Drainage covers and visible utilities
Watercourses and landscape features
Site access points and features
Deliverables are provided digitally in:
DWG / DXF
PDF plans
CSV coordinate files
Point clouds (E57, LAS, PLY)
Revit / IFC models (if requested)
Hard copies can be provided on request.
Yes — we set out:
Foundations
Gridlines
Drainage
Roads and kerbs
Structural steel
Earthworks and levels
All work is carried out by qualified engineering surveyors.
Timelines vary by complexity:
Small residential property: 1–3 hours
Medium commercial building: ½–1 day
Large industrial sites: 1–3 days
Processing and modelling usually take 3–10 working days depending on deliverables.
Costs depend on:
Site size
Complexity
Access conditions
Required deliverables
