What is a measured building survey?
A measured building survey — also called a building measurement survey, measurement survey or architectural survey — is a precise record of an existing building’s dimensions, layout and features. Using 3D laser scanning or traditional measurement methods, the survey produces floor plans, elevations, sections and 3D models that architects, engineers, developers and facilities managers use as the data foundation for design, planning, construction and building management.
Measured building surveys deliver:
- Floor plans, elevations and cross-sections
- CAD drawings in DWG, RVT and IFC formats
- 3D models and point clouds
- Photogrammetry and orthophotos for heritage work
All Red Laser measured building surveys are carried out in compliance with the RICS Measured Survey specification. Processed in-house, quality checked and issued in the agreed formats — ready to use.

How we capture measured building survey data
Red Laser uses Leica RTC360 3D laser scanners as the primary instrument for measured building surveys. The scanner captures up to two million data points per second, producing a complete point cloud of the building — every wall, ceiling, floor, window opening and structural element — in a single site visit. All data is registered and processed in-house by our survey team.

What does a full measured building survey include?
Everything agreed at quote stage — processed in-house, quality checked, issued in the formats you need.
Every measured building survey is scoped to your project requirements. The deliverables below represent the full range available from a complete survey. Your quote confirms exactly what is included.
2D CAD drawings
- Floor plans — Plan views of every floor showing walls, doors, windows, columns and fixed features to the agreed Level of Detail. The most frequently requested deliverable.
- Reflected ceiling plans — Ceiling heights, beams, coffers, light fittings and sprinklers mapped from above. Essential for fit-out, interior design and MEP coordination.
- Internal elevations — Every internal wall face with accurate heights, openings, fixtures and features. Standard for refurbishment, fit-out and interior design projects.
- External elevations — All façades showing external appearance, materials and architectural detail. Required for planning applications, heritage submissions and design development.
- Cross-sections — Vertical cuts through the building showing floor-to-floor heights, structural elements and the relationship between levels. Used by architects and structural engineers.
- Roof plan — Complete roof geometry including parapet heights, plant equipment, roof lights and drainage. Essential for roof replacement, extension and planning work.
3D models
Produced directly from the point cloud. More detailed than traditional measured drawings — used for BIM coordination, design development, clash detection and client presentations.
- Revit model — BIM-ready, IFC-exportable — A fully coordinated 3D model built in Revit. Ready to use in BIM workflows, clash detection and design development. Exportable to IFC for open BIM projects.
- SketchUp model — 3D model in SketchUp format. Used for early-stage design exploration, client presentations and planning visualisations.
- AutoCAD 3D model (DWG) —3D model in DWG format for teams working in AutoCAD-based workflows.
- 3D mesh model — Detailed surface mesh capturing complex geometry, curves and irregular features. Used for heritage recording, conservation projects and buildings where standard modelling methods are insufficient.
Schedules & calculations
Supporting documents derived from the survey data. Commonly requested alongside the main drawing package.
- Window and door schedules — Dimensioned schedule of every opening across the building — type, size, position and reference. Standard for refurbishment specifications, fit-out and planning submissions.
- Area calculations (GIA, GEA, NIA, NLA) — Floor area measurements to RICS Code of Measuring Practice. Used for property valuation, lease agreements, planning applications and space planning.
Point cloud
The raw output of the 3D laser scan — and a deliverable in its own right. A point cloud is a dense set of millions of measured data points capturing every surface of the building to ±1mm accuracy. It contains more information than any drawing or model derived from it, and can be revisited at any time if additional outputs are needed without returning to site.
- Point cloud (E57, RCP) — Importable directly into Revit, AutoCAD, ArchiCAD and Autodesk ReCap. Used by BIM managers, architects and engineers who need direct access to the raw scan data.

How much does a measured building survey cost?
Every project is scoped and priced individually. Quote within 24 hours.
Every project is different.The cost of a measured building survey is determined by the following factors:
- Floor areaThe most significant factor. Larger buildings require more scan positions and more processing time.
- Number of floorsEach floor requires separate scan setup and registration. Multi-storey buildings take longer.
- Level of Detail (LOD)A full measured survey with all fittings, MEP and ceiling detail costs more than a basic structural survey.
- Deliverables requiredA point cloud only is less expensive than a full suite of CAD drawings, 3D model and BIM model.
- Access and complexityRestricted access, unusual geometry, listed building constraints or multi-occupier sites add time on site.
Straightforward pricing. No hidden fees.

Why clients choose Red Laser for measured building surveys
"I must say that at first glance I consider them to be some of the most well-considered survey drawings that I have come across in a long time. Thank you and your team for their obvious diligence."
- Reliable data. ±1mm accuracyYour measured building survey is captured using Leica RTC360 3D laser scanners, to ±1mm positional accuracy across the full building. Every scan station is registered to a controlled survey network — so drawings are geometrically consistent from floor to floor and elevation to elevation. Accurate survey data removes the need for redesign caused by incorrect dimensions. Before any deliverable is issued, it is checked against your project brief by a second surveyor. You receive the files once they have passed QC — not before.
- Itemised quote. No scope surprisesYour quote lists every element — deliverables, drawing scale, Level of Detail, format and delivery programme — before a single scan is taken. What is quoted is what you receive. There are no format revisions or scope additions after the survey is complete, because everything is confirmed before it begins.
- Direct access from day oneWhen you contact Red Laser, everyone you speak to has a professional background in surveying, construction or engineering. That means the person scoping your building survey understands your project — not just the process of booking one. Urgent and next-day site slots are available.

How Red Laser prevents survey errors
Five safeguards on every measured building survey
Professional buyers commission building surveys because the cost of inaccurate data — in aborted design, rework or failed planning applications — far exceeds the cost of the survey itself. These are the safeguards built into every Red Laser project.
- Scope, format or scale wrong on deliveryDeliverables, format, scale and Level of Detail confirmed in writing before mobilisation — floor by floor, drawing by drawing
- Drawings contain dimensional errorsAll deliverables checked against your project brief by a second surveyor before issue
- All data is processed in-house by our survey teamAll deliverables checked against your project brief by a second surveyor before issue
- Access issues cause incomplete captureSite programme and access requirements confirmed before the team arrives on site

Frequently asked questions about measured building surveys
What is a measured building survey?
A measured building survey — also called a building measurement survey, measurement survey or architectural survey — is a precise record of an existing building’s dimensions, layout and features. Using 3D laser scanning, it produces floor plans, elevations, sections and 3D models for use in design, planning, construction and building management. Used at every stage of a building’s life — from planning and design through to refurbishment, acquisition and facilities management.
When do I need a measured building survey?
You need a measured building survey whenever design or construction decisions depend on accurate existing conditions data — typically at the start of a refurbishment, before a planning application, during pre-acquisition due diligence, or when creating a BIM model of an existing building. It is the essential first step for any architect, developer or engineer working with an existing structure.
What deliverables do I receive from a measured building survey?
You receive the deliverables agreed at quote stage — from a floor plan–only package to a full set including CAD drawings, a Revit model, point cloud data and area schedules. Standard outputs include floor plans, reflected ceiling plans, internal and external elevations, cross sections, roof plans, and point cloud in your required format. All deliverables are quality-checked against your brief before issue.
What affects the cost of a measured building survey?
Measured building survey cost is determined by building size and number of floors, the Level of Detail required, the deliverables needed, access conditions on site, and the drawing scale specified. Red Laser provides a detailed, itemised quote within 24 hours — covering every element of scope with no cost surprises after the survey is complete.
How long does a measured building survey take?
Site survey duration depends on building size, number of floors, complexity and Level of Detail required — confirmed at quote stage. The delivery programme for drawings and models is agreed in writing before the survey begins. Urgent and next-day site slots are available for time-critical projects.
Can you carry out a measured house survey on a residential property?
Yes. Red Laser carries out measured building surveys on residential properties of all types — from single-storey extensions to multi-storey period townhouses. The same Leica RTC360 process applies, with deliverables produced at the scale and Level of Detail the architect or planning consultant requires. Surveys on listed residential buildings use non-contact methods throughout.
Does Red Laser follow RICS measured building survey specifications?
Yes. All Red Laser measured building surveys are carried out in compliance with the RICS Measured Survey specification — the governing standard for building measurement across the UK. Area calculations — GIA, NIA, GEA and NLA — follow the RICS Code of Measuring Practice. Compliance is confirmed in project documentation and available on request.
What is the difference between a measured building survey and a building measurement survey?
A measured building survey and a building measurement survey are the same service — the terms are used interchangeably across the industry. Both describe a precise survey of an existing building’s dimensions and layout, producing drawings and models for design, planning and construction use. Red Laser delivers both under the same RICS-compliant process.
