AS-BUILT SURVEYS
As-Built Surveys record what has actually been constructed, installed or altered on site. AMS Surveys can measure completed or partially completed works and provide drawings, point clouds or verification information that gives project teams an independent record of existing construction. This can support handover, design coordination, future alteration, asset records or comparison against issued drawings and BIM information.

TYPICAL PROJECTS AND APPLICATIONS
As-Built Surveys are commonly commissioned for projects such as:
Post-construction records before project handover
Verification of refurbishment and fit-out works
Checking completed building geometry against design drawings
Capturing existing conditions before a later project phase
Creating reliable records where contractor red-line drawings are incomplete
Commercial and estate management where current building information is required
For a broader existing-building package, see Measured Building Surveys. Related AMS Surveys services can be coordinated where the project also requires design, condition or heritage input.
COMMON OUTPUTS PROVIDED
Depending on the agreed scope, AMS Surveys can provide:
As-built floor plans, elevations and sections
Point cloud datasets showing completed conditions
CAD drawings in DWG and PDF formats
Revit or BIM models where included in the brief
Dimensional verification of agreed features
Photographic or survey notes where relevant to the agreed scope

MEASURED BUILDING SURVEY FAQs
Q: What is a measured building survey?
A: A measured building survey provides accurate drawings of an existing property, supporting planning, refurbishment, retrofit and redevelopment work.
Q: Do you work with heritage and listed buildings?
A: Yes, we regularly survey historic and heritage assets, producing elevations and sections suitable for conservation-led projects.
Q: What formats do you provide?
A: Survey drawings are typically issued as PDF and CAD-ready files, tailored to the design team’s requirements.
Q: Is this suitable for commercial buildings?
A: Yes, our measured surveys are commonly commissioned for offices, retail units, industrial buildings and mixed-use developments.
ABOUT AS-BUILT SURVEYS
An as-built survey is different from simply redrawing the design information. It measures the physical building so the record reflects the condition found on site. The required tolerance and extent depend on the reason for the survey. A handover record may need a broad building layout, while verification of a critical opening, structural element or fit-out may require more focused control and tighter checking. AMS Surveys agrees the purpose first, then selects the survey method and deliverables around the information the client needs to rely upon.
