As-built surveys for refurbishment give project teams the dependable existing building information needed before retrofit, fit-out, reconfiguration, and refurbishment work moves into design, pricing, and delivery.
An as-built survey for refurbishment provides an accurate record of a building's existing condition before or during renovation, retrofit or fit-out works. It gives architects, contractors and developers reliable information about the building they are actually working with, rather than relying on outdated drawings or assumptions.
Refurbishment projects often involve existing structures, irregular geometry, previous alterations and building services that are not fully documented. Accurate existing building information allows these conditions to be understood before design and construction decisions are made.
At Geo Scan, we capture existing building conditions using measured survey techniques , 3D laser scanning and other appropriate surveying technologies. The resulting information can be delivered as measured drawings, point clouds, CAD files or BIM models according to your project requirements — as part of wider as-built survey programmes.
A detailed as-built survey can help reduce design risk, improve pricing accuracy and support better coordination between architects, engineers and contractors — with methodology aligned to RICS measured survey guidance . See our as-built handover guide for post-refurbishment records.
Survey data is processed and checked against the agreed specification, aligned with RICS measured survey guidance , before drawings, point clouds or BIM models are issued.
Refurbishment projects frequently take place while buildings remain operational. We plan survey activities around access restrictions, tenants, staff, contractors and site programmes — using fast non-intrusive scanning where appropriate to minimise disruption while capturing detailed existing-condition information.
Our process is designed to reassure busy refurbishment teams: clear brief, planned access, fast capture, QA, and delivery aligned to design and construction programmes.
We review scope, constraints, access windows and programme milestones, then agree deliverables and formats. Contact us to discuss occupied areas, phasing and site logistics before capture.
Measured survey and 3D laser scanning capture complex existing conditions with minimal disruption — coordinated with measured survey workflows on live refurbishment sites.
Survey data is registered, checked and issued as CAD, PDFs, BIM models and point clouds — aligned to as-built and measured survey specifications and RICS measured survey principles.
Final deliverables in agreed formats (DWG, PDF, RVT, IFC, LAS/LAZ/E57) integrated into your design and construction workflow.
An as-built survey for refurbishment is an accurate record of the existing building before or during renovation, retrofit or fit-out works. It helps reduce design assumptions and identify constraints early — supporting wider as-built survey programmes and handover planning .
Offices, retail, hospitality, residential and mixed-use refurbishments — including occupied and live sites. For London-specific enquiries, see As-Built Surveys London and our parent as-built surveys service.
Floor plans, elevations, sections, 2D CAD, PDFs, registered point clouds and BIM models (RVT/IFC) where required — via measured building survey , 3D laser scanning and scan-to-BIM workflows scoped to each project.
Timelines depend on building size, complexity, access and deliverables. Site capture may range from part of a day to several days; processing and drawing production follow the agreed scope. Contact us for a project-specific programme and quotation.
We coordinate access and working hours with site managers. 3D laser scanning and measured survey methods capture detailed information quickly with minimal impact on occupants and ongoing works.
Yes. Survey and 3D laser scanning data can be used to create BIM models for refurbishment and retrofit projects, supporting architectural design, spatial coordination, clash detection and MEP integration — including heritage and complex buildings (see scan-to-BIM for listed buildings ).
Typical formats include DWG, PDF, RVT, IFC and point cloud formats such as LAS, LAZ and E57 — agreed during survey specification alongside measured survey , laser scanning and as-built deliverable requirements.
Yes. We can provide updated as-built drawings and digital models following refurbishment works for handover, O&M documentation and facilities management — see our as-built handover process guide and as-built survey service.
