How to Brief a Measured Surveyor: What to Send Before You Ask for a Quote
You do not need a complicated technical specification before asking for a measured building survey quote. The most useful starting points are what the survey is for, who will use it, which parts of the property need to be covered, what drawings or models are required, and anything that could affect access. Existing plans, photographs and project information can also help a surveyor establish an appropriate scope.
A good measured survey brief is not about knowing surveying terminology. It is about giving enough context for the right areas to be measured and the right information to be delivered.
The person requesting the survey is not always the person who will use it. Starting with the end use can make the quotation clearer and help avoid commissioning detail the project does not need.
You do not need a perfect measured survey specification to ask for a quote
Every project is different. A residential extension may need a very different scope from a commercial refurbishment, heritage project or 3D modelling brief.
If an architect or consultant has prepared a measured survey specification, send it over. If not, explain what the project is trying to achieve and what the information will be used for. A specialist surveyor can then help clarify the level of detail and deliverables.
For readers who are still working out the basics, our guide to what a measured building survey includes explains how measured surveys can provide floor plans, elevations, sections and other accurate as-built information.
What information should you send for a measured building survey quote?
The following information helps a surveyor understand the likely scope without making the enquiry unnecessarily complicated.
1. Explain what the survey is for
Start with the purpose of the project. Are you planning an extension, refurbishment, redevelopment, interior fit-out, planning application or another form of design or construction work?
The intended use helps determine how much of the building needs to be captured and how much detail is appropriate.
2. Say who will use the survey
If an architect, designer or consultant has asked you to arrange the survey, find out what they actually need, such as particular areas, elevations, sections or a specific file format.
For example, if you are planning a rear extension, your architect may only need detailed information for the affected part of the building rather than a full survey of every room.
3. Describe the property and the areas to be surveyed
Provide the address, a simple description of the building and, if known, the number of floors. Say whether you need the whole property surveyed or only selected areas.
4. Confirm the drawings or model you need
A measured building survey can produce floor plans, roof plans, sections, elevations, 2D CAD drawings and 3D models. You do not automatically need every possible output.
If your design team needs a 3D Revit model, IFC files or information for a BIM workflow, mention this at the quotation stage. Our BIM and 3D modelling service can support projects that need reliable digital as-built information.
5. Send any plans, sketches, photographs or existing information
Existing floor plans, an architect’s mark-up, a property listing, photographs or even a rough sketch can help explain the building and the areas involved.
This reduces assumptions when the survey is scoped. The information provides context and does not replace professional measurements on site.
6. Forward any survey specification you have
If you have a written specification covering accuracy, detail, drawing content or output format, send it with the enquiry rather than trying to summarise it.
If you do not have one, explain what the information needs to achieve and the scope can be agreed from there.
7. Flag anything that could affect access
Mention if the building is occupied, tenants need notice, areas are locked or restricted, or the surveyor will need an induction, escort or other site arrangement.
Anything unusual that could affect access is useful to know and can help the site visit run efficiently with minimal disruption.
8. Give the project timescale
Explain when the site survey needs to happen and when the finished drawings or model are required.
If you are not sure when to commission the work, our guide to when to order a measured building survey gives some useful context.
What if your architect has simply said, “We need a measured survey”?
This is common. You do not need to write the specification yourself. Ask three straightforward questions:
- Which parts of the property need to be surveyed?
- Which drawings or models do you need?
- Which file format should the information be supplied in?
If they have a marked-up plan or specification, forward it. If not, explain the project and intended use and agree the scope from there.
A clearer brief can help avoid paying for information you do not need
A well-defined scope helps ensure the survey produces accurate, reliable as-built information for the next stage of the project. More detail is not automatically better. The right scope is the one that matches the job.
For example, an interior designer may need detailed elevations in selected rooms, while an architect designing an extension may only need plans, elevations and a section around the proposed works. A team working in 3D may benefit from receiving a Revit model rather than recreating 2D information later.
If the project also depends on levels, boundaries, contours or surrounding site features, discuss whether a topographical survey should be scoped at the same stage.
What if you do not have all this information yet?
Do not delay an enquiry because you cannot answer every question. An address, a short explanation of the project and any plans or photographs you have are a good starting point.
