Geo Scan records agreed visible and accessible building or installed features at the time of survey. Architects, contractors and property teams receive a clearly scoped current record for design, coordination, refurbishment or handover.
Old drawings can miss later alterations, changed layouts or installed features. An as-built survey creates a dated record of the agreed building or installation state so the next project stage starts from measured information.
The brief determines what we capture and what we produce. An existing floor plan, a detailed section through an interface and an as-installed services record need different coverage and production effort.
An as-built survey defines the areas, features and state to record. If your requirement is specifically a measured DWG/PDF drawing package produced from Geo Scan capture, use Scan to CAD.
For a general building measurement brief, see measured building surveys. For retrofit, fit-out or reconfiguration, explore as-built surveys for refurbishment.
We agree required accuracy and the checking approach for the intended use. Control, registration, field conditions and output interpretation matter alongside the capture equipment. Tell us about critical dimensions, levels or interfaces before the survey so the method and deliverables can address them.
A surveyed record does not by itself certify regulatory compliance, structural adequacy, legal boundaries or concealed services.
Define areas, outputs, section positions, required accuracy, coordinate system and the decisions the survey must support.
Use measured survey methods and, where appropriate, terrestrial laser scanning. Record access restrictions and coverage gaps.
Process and register the data, then draft or model the agreed information. Check the outputs against the captured record and scope.
Supply the agreed files with drawing references, survey date, revision information and relevant coverage or interpretation notes.
An as-built survey records the building or installation as it exists at the time of capture. Its agreed outputs may include floor plans, elevations, sections, a point cloud or a model. The record covers the agreed areas and accessible, observable features; it does not reveal concealed construction.
The methods often overlap. A measured building survey describes the measurement of existing geometry. An as-built survey emphasises the record of what is actually present, including existing conditions or installed work. Tell us the decision you need to make so we can agree the appropriate scope.
Survey information can support an agreed comparison against supplied design information. The reference drawings, coordinate system, items to check and acceptance criteria must be defined first. A measured record alone does not certify workmanship, regulatory compliance or structural adequacy.
Required accuracy is agreed for the intended use. Survey control, capture conditions, registration, checking and drawing interpretation all affect the result. There is no single tolerance that suits every building or deliverable; critical dimensions and interfaces should be identified in the brief.
Access, working hours, occupancy and obstructions are reviewed before the visit. Restricted areas or hidden surfaces may need additional access or a return visit. We agree how coverage gaps will be recorded rather than presenting unseen areas as measured.
The quotation depends on building size and complexity, access, survey coverage, required detail, outputs and programme. Send the address, available plans, the areas to include and your target date. Capture and drawing or modelling time are considered separately.
