What Our As Built Surveys Provide
We verify structural gridlines, primary setting-out points and control stations so you can demonstrate that the frame has been built in the correct position.
Foundations, piles, pile caps and ground beams are measured and checked against design coordinates and levels for compliance and record purposes.
Columns, steel frames, RC cores and structural walls are surveyed to confirm geometry, position and plumb, supporting structural verification and follow-on trades.
Finished floor levels (FFL), slab edges, steps, ramps and soffit levels are recorded to support cladding, partitions, MEP installation and tolerances.
Internal partitions, room layouts, door and window openings and key fit-out elements are captured so as built layouts can be compared directly with approved plans.
Brickwork, blockwork, cladding lines, curtain walling and façade positions are surveyed to support elevation checks, interfaces and external tolerance control.
Kerbs, roads, pavements, ramps, car parks and hard landscaping are measured as built for drainage, access, levels and completion documentation.
Where required, visible MEP routes, plant locations, risers and main service runs are captured to support coordination, record drawings and future maintenance.
As Built Survey Workflow
Scope and requirements
We define the as built survey scope, elements to be checked, design drawings to compare against, required tolerances, coordinate system and deliverables.
On-site as built survey
Our surveyors establish control and capture as built data using Leica total stations and 3D laser scanning, working efficiently around live construction activities.
Data processing and comparison
Measurements are processed into as built CAD drawings, schedules and models, then overlaid against design information to highlight variances and tolerance issues.
Final deliverables
We issue DWG as built drawings, scaled PDFs, variance reports and, where required, BIM-ready as built models and point clouds — clean, coordinated and ready for QA, building control and handover.
Applications of Our As Built Survey Services
Objective evidence that structural and architectural elements have been built within specified tolerances and align with construction drawings.
Piles, RC frames, steel frames, cores and substructure checked as built before cladding, façades and internal fit-out proceed.
As built information for floor levels, slab edges, walls and openings supports façade installation, partition setting-out and MEP coordination.
As built drawings and reports support building control submissions, completion certificates, warranties, O&M manuals and health and safety files.
Reliable record for landlords, building owners and facilities managers planning future fit-out, maintenance or refurbishment.
As built data used to update BIM models and digital twins so design-intent models reflect what has actually been constructed.
Accurate as built survey information reduces disputes, supports claims and provides a long-term record of completed construction.
Why Clients Choose Us as Their As Built Surveyor
Specialist experience in as built surveys, construction verification and tolerance checks on live projects.
Structured CAD drawings, record surveys and BIM-ready as built models that drop straight into architects’ and engineers’ environments.
Consistent site control, measured survey methods and internal QA procedures to maintain high precision and repeatable results.
Efficient survey programming, fast mobilisation and deliverables aligned with construction programmes and handover dates.
Transparent fees based on clearly defined scope, with competitive pricing on London and UK construction projects.
Understanding of how contractors, engineers and design teams use as built data for QA, sign-off and future works.
We operate as a dedicated as built survey partner, providing accurate, verifiable data that can be relied on throughout the construction lifecycle.
Output Standards
GA plans, elevations and sections issued in DWG with scaled PDF plots for easy review by project teams and stakeholders.
Professional drawing scales such as 1:50, 1:100 or 1:200 appropriate for structural verification, fit-out and record drawings.
Clear layering, line work, grid references and annotation so drawings can be understood quickly and used directly in CAD and BIM.
Optional variance reports and highlighted overlays showing differences between as built survey results and design or IFC drawings.
Surveys related to OS grid, site grid or structural grid as required for setting-out, coordination and future survey work.
Internal checks on control, levels and measurements to maintain accuracy and the highest standards of survey data.
These outputs are suitable for QA documentation, construction verification, BIM updates and long-term record information.
