A measured building survey records the dimensions, geometry and visible features of an existing building. It is typically presented as floor plans, elevations and sections, giving your team a measured basis for design, planning, refurbishment and fit-out.
A measured building survey records the dimensions, geometry and visible features of an existing building. It is typically presented as floor plans, elevations and sections, giving your team a measured basis for design, planning, refurbishment and fit-out.
The building and the decisions you need to make determine the coverage and drawing detail. Roof plans, reflected ceiling plans, area schedules, 3D models and point cloud data can be included in the agreed package.
These are the principal drawing outputs of a measured building survey. Choose the views that explain the building and support the work your team is planning.
Layered CAD drawings and PDF issue sheets are supplied in the agreed formats. Dimensions, levels, annotations, drawing scale and detail are defined in the survey specification.
Horizontal views of each agreed floor, recording the layout, walls, openings, stairs and visible features.
For space planning, layout design and understanding circulation.
DWG / PDF
External or internal views recording building faces, openings, heights and architectural detail to the agreed specification.
For façade design, planning drawings and alterations to existing spaces.
DWG / PDF
Selected vertical cuts through the building, showing floor levels, room heights, stairs and roof relationships.
For resolving changes in level, vertical clearances and structural interfaces.

A survey can cover the whole building or a defined part. Include additional views and schedules where they answer a specific project question.
Roof layout, outlines and agreed visible roof features.
Ceiling geometry, levels and selected visible services or fixtures.
IPMS, GIA or NIA measurements to the agreed basis and extent.
Surrounding levels and external features through a coordinated topographical survey.
Measured building information can be supplied as drawings, a survey-based model, point cloud data or a combination. Choose the representation your team will use, then agree its coverage and detail.
Start with the purpose of the survey. A well-positioned section may resolve the question; a coordinated model may be more useful when your team needs to work with building elements in 3D.
Floor plans, elevations, sections and other agreed views prepared from Geo Scan’s own laser scan survey data. Coverage, drawing detail and file requirements are agreed around your project.
DWG / PDF
Building geometry developed into a structured survey-based model for your design workflow. Agree the elements, modelling detail, tolerances and exchange requirements before production.
RVT / IFC
Work directly with the measured 3D dataset, or use it alongside the drawings. Cleaning, organisation, sampling and software requirements are agreed for the handover.
E57 / RCP or agreed format
“Measured building survey” describes the measurement and recording of a building. “As-built” describes information about what exists or has been constructed. A measured survey can therefore produce as-built drawings or models. For verification of installed work or a record at a particular project stage, agree that purpose explicitly.
Develop proposals from a measured existing layout, elevations and level relationships.
Understand altered spaces and interfaces where existing drawings are incomplete or out of date.
Record irregular geometry and agreed architectural detail for conservation and change.
Create consistent layout and area information across buildings and property portfolios.
We combine surveying expertise with 3D laser scanning and appropriate control, then interpret the measured data into the agreed drawings or models.
The typical outputs are floor plans, elevations and sections. Roof plans, reflected ceiling plans, schedules, models and point clouds can also be included. The quotation identifies the areas and outputs in your particular package.
Yes. The measured information can be developed into a survey-based Revit model or supplied in an agreed IFC exchange format. Model elements, detail and tolerances are specified for your intended workflow.
A measured building survey records dimensions and geometry. A condition or structural survey assesses defects or performance. Those assessments are separate specialist services; a measured survey does not replace them.
Yes. A brief can cover selected floors, rooms, façades or section positions. Tell us which interfaces and surrounding context your design needs so the scope provides useful information.
Accuracy is specified for the intended use, site conditions and critical interfaces. Drawing scale and scanner specifications alone do not establish the accuracy of the finished survey.
Survey accuracy and specification
Yes. We agree access, working hours and phasing with the site team. Restricted or obscured areas are identified, and any return visits or additional access requirements are agreed.
Timescales depend on the extent, complexity, access and required outputs. Site capture, processing and drawing or model production are distinct stages. We confirm a project-specific programme with the quotation.
Send the site address, building extent, intended use, required outputs, access information and target issue date. Existing drawings, a survey specification or an example deliverable help us define and price the brief.
