Measured Building Surveys and As-Built Surveys

A measured building survey gives you accurate plans, sections and elevations of an existing building; an as-built survey records what was actually constructed. Based in Lymington with an office in London, we survey across Hampshire, Dorset and nationwide.

Measured building surveys

We produce both from Leica RTC360 laser scans, so every dimension traces back to a point cloud you can check.

We scan the whole building inside and out, then draw from the point cloud. Because the cloud records every surface, drawings are complete and can be re-measured later without a return visit.

  • Floor plans and reflected ceiling plans
  • Sections and elevations
  • Roof plans from drone capture
  • Area schedules (GIA and NIA) to RICS Property Measurement
  • Delivered in DWG and PDF, with the point cloud in E57 or RCP

Used for planning applications, lease plans, refurbishment and extension design, fit-out tenders, dilapidations and party wall work.

As-built and construction verification surveys

We scan at the stages that matter (slab, frame, pre-cover-up, completion), compare the point cloud against the design model and report deviations with colour-coded heat maps and tables. As project managers and contract administrators ourselves, we know which deviations affect the next trade, the payment certificate or the handover file.

  • Slab flatness and level checks before frame or fit-out
  • Steel frame and envelope position against the structural model
  • Services routes before ceilings close
  • Completion as-builts for O&M and the building safety record

Outputs: deviation report, as-built point cloud, updated Revit or IFC model where required.

Why a laser-scanned survey

  • A complete record of the building, not just the dimensions someone thought to take
  • Re-measure from the point cloud at any time without revisiting
  • No scaffold or access equipment for most elevations; roofs by drone
  • Occupied buildings surveyed without disruption
  • One firm from capture to drawings: no handoff between a survey company and a CAD bureau

Turnaround

A single building is usually captured in a day. Registration and QA follow within 48 hours. Drawings typically take 5 to 10 working days from capture. We quote per project; send us the address, the areas and what the survey is for and we will quote within one working day.

Frequently asked questions

What is the difference between a measured building survey and a topographical survey?

A measured building survey records the building itself: plans, sections and elevations. A topographical survey records the land around it: levels, boundaries, trees and services. We provide both, the latter by drone photogrammetry.

Do I need a measured survey for a planning application?

Planning drawings must show the existing building accurately. A laser-scanned survey gives your architect true geometry, which avoids corrections after validation and disputes with neighbours over heights and distances.

What accuracy do I get?

Registered point clouds are typically within 2 to 5 mm; drawings are produced to the tolerance we agree with you, usually 10 mm for building surveys. The point cloud is supplied so any dimension can be checked.

Can you survey an occupied building?

Yes. Scanning is non-contact and quiet. We plan stations to avoid people in the data and can work out of hours.

How much does a measured building survey cost?

We quote per project based on floor area, complexity, the outputs you need and access. Send the address and a short brief and we will quote within one working day.
