What is AR floorplan capture for site surveys?

AR floorplan capture uses the camera and motion sensors on a smartphone or tablet to measure spaces and generate accurate digital floor plans as you walk around a building. The app overlays a real-time spatial grid onto the camera view, allowing the surveyor to mark corners, walls, doors, and windows by pointing at them rather than measuring manually.

How accurate are AR-generated floorplans?

On LiDAR-enabled devices, SiteSurvey AR floorplans typically achieve dimensional accuracy within 1 to 2% of the true measurement for rooms up to 20 metres in length. For a 10-metre wall, this translates to a variance of roughly 10 to 20 centimetres, which is acceptable for the majority of commercial survey, space planning, and fit-out applications.

What equipment do I need to capture AR floorplans on site?

To capture AR floorplans with SiteSurvey you need a compatible iOS or Android smartphone or tablet. No additional hardware is required to get started. The SiteSurvey app is available from the App Store and Google Play, and AR capture is included as part of the standard platform.

How long does it take to capture an AR floorplan on site?

A standard rectangular room of 20 to 50 square metres typically takes 2 to 5 minutes to capture using SiteSurvey AR floorplan capture. A full floor containing 10 to 15 rooms, including corridors and ancillary spaces, can usually be completed in under an hour by an operative working at a normal pace.

Can AR floorplans be exported to CAD or other formats?

Yes, AR floorplans captured in SiteSurvey can be exported in multiple formats from the web portal. DXF export allows plans to be opened and edited in AutoCAD, DraftSight, or any other CAD application that supports the DXF interchange format. This is the most commonly requested export for design, fit-out, and building management workflows.

How does AR floorplan capture compare to traditional tape measure surveys?

AR floorplan capture is faster than a traditional tape measure survey for most commercial spaces. Where a tape survey requires two people to measure each wall, record dimensions on a hand sketch, and then redraw the plan in a CAD or drawing package after leaving site, AR capture produces a dimensioned digital plan in real time as the surveyor walks the space. A single surveyor can capture a room with AR in the time it would take a pair to set up a tape for one wall.

Floor plans and space mapping

Walk the site.
Get the plan.

Point the phone and walk the rooms. SiteSurvey draws the floor plan as you go — doors, windows and stairs included — then turns every room into a space the office can open on the web.

A plan that builds itself

The floor plan is the survey — not an attachment to it.

No drawing to source, no tape measure, no CAD. Walk the building once and the whole team opens the same layout, with everything captured in each room attached to it.

Capability 01

Multi-room capture

Map room after room in a single session. Name each space as you finish it and watch the live plan take the shape of the building.

Capability 02

Doors, windows and stairs

Tag openings as you walk past them so the plan reads like a real drawing — including stair runs marked as their own space.

Capability 03

Polished in one tap

Polish squares the rooms, closes the gaps to wall thickness and draws real walls. Restore brings the raw capture straight back.

Capability 04

Or start from a drawing

Already have a PDF or CAD export? Upload it as the floor plan and position the spaces on it instead — everything after that is identical.

How the capture works

Point, tap, mark the openings, lock the length.

Nothing to set up and nothing to draw. Aim the phone at a corner and tap — then tell it where the doors and windows are, and lock in any length you already know is right.

Aiming the phone at a corner in augmented reality — a dotted measuring line extends to the corner and the length appears as a chip along the top — Step 01
Tap corner to corner
Aim at a corner and tap. The length lands in the room and the wall joins the plan you are building.

Tapping Window, then marking across a shuttered window — a 2.33m window is added to the plan — Step 02
Mark a window
Tap Window, then the two edges of the opening. It goes onto the plan at its real width — 2.33 m here.

Tapping Door, then marking across a doorway — a 0.85m door opening is added to the plan — Step 03
Mark a door
Same for doors and stairs. Mark them as you pass and the finished plan draws the opening where it belongs.

Adjusting a measurement from 7.60m to 8.00m on a slider, then tapping Lock so the measurement turns gold with a padlock — Step 04
Adjust it, then lock it
Know a wall is exactly 8 m? Slide to correct it and tap Lock. The length is trusted, and the opposite wall snaps to it.

Saving the walk creates a space for every room and syncs the layout. Office users see the whole floor on the Map, click into any room and find the products, forms, photos and sign-off captured there.

AR measurement

Measure what the plan cannot tell you.

Inside a space, switch to elevation and measure the things a floor plan leaves out — door heights, wall drops, mounting positions. Point the camera and tap corner to corner, with no tape measure and no drawing to start from.
