Measured surveys, built around your project

Floor plans, elevations, topographical surveys, point clouds, Revit models and more. Use one of our survey services on its own, or combine several into one coordinated measured survey.

__ What is a measured survey?

One service, several combined, or the whole building

A measured survey creates an accurate record of a building or site as it exists today. It isn’t one fixed product. Depending on your project, it can be a single survey service or several brought together, captured on one visit and delivered as one coordinated set of information.

Option 1

On its own

Just need one thing? Each of our measured services can be ordered individually.

For example: a topographical survey for a planning application.
Option 2

Combined

Pick the services you need and we’ll capture them together, tied to the same survey control.

For example: a topo survey plus elevations and roof plans for an extension.
Option 3

Full measured building survey

Everything inside and out: floor plans, elevations, sections, roof plans and a model if you need one.

For example: a Revit model of an occupied office for a refurbishment.
__ How it comes together

Different capture methods, one set of data

We choose the right mix of capture methods for your project, then register everything into one coordinated dataset. That’s what lets internal, external, roof and site information line up.

Step 2

Level of detail

Not sure? That’s fine. We’ll recommend the right level, so you don’t pay for detail you won’t use. See what each level means.

__ Our measured survey services

The building blocks of a measured survey

Each of these can be ordered on its own, or combined as part of a wider measured survey.

__ Typical combinations

How clients put their surveys together

A few examples of how our services combine for common projects.

Planning an extension

An architect needs accurate existing drawings to design around.

Services
CAD drawings + Topographical survey
Outputs
Floor plans, elevations, roof plan, site levels

Refurbishment or retrofit

A design team working in Revit on an occupied building.

Services
Point clouds + Revit model
Outputs
Registered point cloud, Revit model at LOD 300

Buying or developing land

A developer assessing a site before design work starts.

Services
Topographical survey + 3D modelling
Outputs
Topo in CAD, contours, 3D site model

Estate and portfolio records

A property team with missing or out-of-date drawings.

Services
CAD drawings + Digital twins
Outputs
Floor plans and virtual tours for every building
__ Levels of detail

Only pay for the detail you need

The level of detail (LOD) depends on how the drawings or model will be used. Lower levels suit feasibility and space planning, while detailed design and BIM coordination need more. Choosing the right level keeps costs down, speeds up turnaround and stops CAD or Revit files becoming more complex than your project needs.

Roofs at LOD 100
__ When you need one

When is a measured survey required?

Planning, extensions & alterations

Accurate plans, elevations and dimensions so architects can design around the existing building.

Refurbishment & retrofit

Existing layouts, levels, openings and geometry, so work is planned around the building as it really is.

Revit & BIM projects

Point clouds and Revit models that give design teams a coordinated existing-building record.

Asset & property management

New or updated records where drawings are missing or out of date, for maintenance and space planning.

Commercial portfolios

Offices, industrial, retail, residential blocks and public estates, with consistent drawing standards across every site.

Higher-risk buildings

Up-to-date plans and elevations can form part of the golden thread of information. A measured survey supports this record, but doesn’t by itself demonstrate compliance with the Building Safety Act.

__ Accuracy & control

Planned around how the data will be used

The accuracy you need depends on what the information is for. Before we attend site, we agree:

  • The accuracy and level of detail required
  • The coordinate system, where data needs to sit on real-world coordinates
  • Survey control and ground control points
  • Drawing standards and final file formats

For guidance on accuracy and detail, see the RICS Measured surveys of land, buildings and utilities guidance note.

__ Pricing

How much does a measured survey cost?

It depends on the size and complexity of the building or site, the number of floors, access, the areas surveyed and the outputs you need. Projects range from data capture or a point cloud only, to full packages of drawings and Revit models.

To quote, we’ll need:

  • The property address
  • Approximate size and number of floors
  • Any existing plans (helpful, not essential)
  • The outputs and level of detail you need

Frequently asked questions

If yours isn’t covered here, give us a call on 0345 017 5592.

Can I order just one of these services?

Yes. Every measured survey service can be ordered on its own. If you need more than one, we’ll capture them together on the same visit, so the data lines up.

How accurate is a measured survey?

It depends on how the information will be used. Survey control and ground control points can be used where greater accuracy is needed, and we agree accuracy requirements before capture.

How do I know what level of detail I need?

The right LOD depends on how the drawings or model will be used. Tell us about your project and we’ll recommend a level that avoids unnecessary modelling, time and cost.

Can internal, external and roof data be combined?

Yes. We combine LiDAR, drone data and survey control to create one coordinated record of internal areas, elevations and roofs.

Do I need a measured building survey or a topographical survey?

A measured building survey records the building itself, while a topographical survey records the land, levels and external site features. Many projects need both, and we can capture them together.

Do I need existing drawings?

No. Existing drawings are helpful but not essential. We regularly survey buildings where plans are missing, out of date or inaccurate.

Can you survey an occupied building?

Yes. Surveys can usually be carried out in occupied buildings, with access and working arrangements planned beforehand to minimise disruption.
