Accurate 3D Laser Scanning for Existing Buildings and Sites
Pinpoint Mapping provides professional 3D laser scanning across Bristol, Bath and the South West for buildings, structures and external sites. Survey-grade laser scanning captures visible surfaces from a series of coordinated positions, creating a detailed three-dimensional record of the existing conditions.
The registered scan data can support architectural design, refurbishment, construction planning, heritage recording and as-built documentation. Depending on the agreed brief, it can be supplied as point cloud data or used to produce 2D survey drawings and three-dimensional models.
Where floor plans, elevations and sections are required, the same captured information can support our measured building surveys. External levels, boundaries and site features can also be coordinated with a topographical survey.
Survey at a Glance
- Survey-grade Trimble X9 site capture
- Internal, external or combined coverage
- Registered three-dimensional point clouds
- DWG and PDF survey drawings where required
- Revit and BIM models to an agreed scope
- Survey accuracy and control matched to the brief
The required coverage, level of detail, survey control and final deliverables are confirmed before site attendance.
What We Deliver from a 3D Laser Scan
The final survey outputs are selected to suit the receiving software, intended project use and level of detail agreed within the brief.
Registered Point Clouds
Registered three-dimensional survey data can be supplied for viewing, measurement and use in compatible survey, design and modelling software.
See the separate 3D point cloud data service for available formats and data-only project requirements.
2D Survey Drawings
Floor plans, roof plans, elevations, sections and other measured drawings can be produced from the registered scan data where these form part of the commissioned work.
Finished drawings can be supplied in DWG and PDF formats to the agreed survey scope.
Revit and BIM Models
Three-dimensional building models can be developed by interpreting the registered laser scan data where Revit or BIM deliverables are required.
The model content, level of detail, software version and information requirements must be agreed before production.
Choosing the Correct Survey Output
A point cloud, a set of measured drawings and a BIM model are different deliverables. The correct option depends on the technical capability of the project team and how the measured information will be used.
Clients with suitable point cloud software may only need the registered survey data. Architects and property professionals often require finished 2D drawings, while coordinated design projects may require a separately specified three-dimensional model.
We confirm the intended workflow before the survey so the site capture and processing are planned around the final output.
When Is 3D Laser Scanning the Right Survey Method?
3D laser scanning is particularly useful when a project needs detailed existing-condition information across complex, irregular or extensive areas.
Project Situations Suited to Laser Scanning
- Refurbishment, extension and alteration projects
- Complex or irregular buildings and structures
- Heritage properties with detailed architectural features
- Commercial buildings, warehouses and industrial premises
- As-built records before or after construction work
- Plant areas and geometry that are difficult to measure manually
- Projects requiring coordinated internal and external information
- Sites where comprehensive capture can reduce avoidable return visits
Laser scanning records visible surfaces only. Furniture, machinery, stored materials, vegetation, vehicles and inaccessible areas can obscure parts of a building or site, so access and survey coverage are reviewed before attendance.
The survey method is selected to suit the site conditions, required accuracy, level of detail and intended outputs. Laser scanning can be used on its own or combined with other measured survey methods.

Our 3D Laser Scanning Process
The site work, data registration and final outputs are planned around the agreed project requirements.
01
Review the Project
We review the site, required coverage, access arrangements, intended use, survey control and final deliverables.
02
Capture the Site
The agreed buildings, structures or site areas are captured from a series of coordinated Trimble X9 scan positions.
03
Register & Check
The individual scans are registered into a coordinated point cloud and reviewed against the agreed requirements.
04
Prepare Outputs
The agreed point cloud, survey drawings or three-dimensional model is prepared, checked and supplied.

We support projects across Bristol, Bath and the wider South West, with clear communication from the initial enquiry through to delivery.
3D Laser Scanning FAQs
Answers to common questions about survey accuracy, point clouds, CAD drawings, BIM models, site access and project requirements.
What is a 3D laser scanning survey?
A 3D laser scanning survey captures visible surfaces across a building, site or structure from a series of coordinated scanner positions. The individual scans are registered together to create a detailed three-dimensional point cloud that can support measurement, drawings, models and as-built records.
How accurate is 3D laser scanning?
The achievable accuracy depends on the project specification, scanning distances, site conditions, registration method, survey control and intended use. We agree the required survey scope and workflow rather than applying one general accuracy figure to every project.
What is a 3D point cloud?
A point cloud is a three-dimensional dataset containing millions of measured points that represent the visible shape and position of surveyed surfaces. Depending on the agreed workflow, data can be exported in formats such as E57, LAS, PTX, RCP and Trimble formats for compatible software.
Can you provide 2D CAD drawings from the scan data?
Yes. Registered laser scan data can be used to produce floor plans, roof plans, elevations, sections and other measured drawings where these are included within the commissioned work. Drawings can normally be supplied in DWG and PDF formats.
Can you provide Revit or BIM models?
Yes. Laser scan data can support Revit and BIM model production. The model scope, level of detail, required content, software version and final outputs should be agreed before the survey and production work begin.
When should I use laser scanning instead of traditional survey methods?
Laser scanning is particularly useful for complex or irregular buildings, heritage properties, industrial premises, detailed as-built records and projects requiring coordinated internal and external information. The final method is selected according to the site, required accuracy, level of detail and intended outputs.
How long does a 3D laser scanning survey take?
The site time depends on the building or site size, complexity, access, required coverage, scan settings and working restrictions. Processing and production time also depends on whether the final deliverable is a point cloud, a set of drawings or a three-dimensional model. We confirm the expected programme within the quotation.
Do you provide 3D laser scanning in Bristol and Bath?
Yes. Pinpoint Mapping provides 3D laser scanning across Bristol, Bath and the wider South West. Projects farther afield can also be considered depending on the survey scope and required programme.
What information do you need to provide a quotation?
Please send the site address, approximate building or site size, required survey areas, internal or external coverage, intended use, required outputs, access arrangements and timescale. Existing plans, photographs, marked-up drawings and project specifications are particularly helpful.
