The Precise Digital Record of Your Structure

As-Built Steel Surveys

By utilising point cloud data captured during a single laser survey, a precise as-built steel survey can be completed — delivering an accurate digital record of your structure's real-world geometry, connections and dimensions.

As-built steel surveys are increasingly specified across construction, refurbishment and infrastructure projects where the difference between design intent and installed reality needs to be clearly understood. Clients use them for a range of purposes including structural analysis, fabrication verification, clash detection and retrofit planning. These surveys provide a reliable dimensional foundation that hand measurements and legacy drawings simply cannot match.

One of the key advantages of an as-built steel survey is the ability to extract both 3D and 2D outputs from the same point cloud dataset. A full 3D model can be produced in formats including Revit, AutoCAD and Tekla, while 2D outputs such as elevations, sections and setting-out drawings can be generated to any required level of detail. Steel members, connection plates, bolt groups and weld positions can all be captured and documented accurately — giving fabricators, engineers and contractors a single trusted source of as-built dimensional data for the entire structure.
AutoCAD & Revit Deliverables
As-built steel surveys can be delivered in either AutoCAD or Revit format depending on your workflow — both fully compatible with Advance Steel for direct use in fabrication detailing, connection design and structural documentation.

AS-BUILT STEEL SURVEY Applications

FABRICATION VERIFICATION
Confirm installed steelwork matches fabrication drawings before handover/
RETROFIT & REFURBISHMENT
Capture existing steel geometry to inform new design around live structure/
CLASH DETECTION
Identify conflicts between structural steel and MEP services before they occur/
STRUCTURAL ANALYSIS
Provide accurate dimensional data to structural engineers for load and stress calculations/
SETTING OUT VERIFICATION
Check installed steel against design coordinates and tolerances on site/
PLANNING & DEMOLITION
Produce a complete as-built record of existing steel prior to alteration or removal/

As-built steel surveys give fabricators, engineers and contractors a single trusted dimensional record of the structure as it was actually built
