About this real-data study

Site-visit photography, a display sample spanning a merged floor cloud and linework from the original GA. The photo-to-cloud move is an editorial transition; the photo has no calibrated scanner-camera pose. Dimensions are calculated between GA column centres: 8,612, 8,613, 8,986 and 8,785 mm. The handwritten notes read “Windows, south-facing light”, “Mullions encased in aluminium cover” and “See Column Fit drawing”. These illustrate a review; material and orientation notes need project verification. Anonymised study, not a construction drawing.

T&I / Digital project work

A clearer picture
of what’s there.

Turning building scans into something a project team can use: a view of the space, a section through it, a record to refer back to.

From the working data

One scan. Different ways to read it.

These are real extracts from our derived data. Each shows a different way of understanding the same part of a building.

Anonymised, cropped study views. Project names, locations and identifying annotations have been removed. Examples only, not drawings for construction.

01 / Spatial context

Point-cloud cutaway

A view made from the captured points, with the overhead layer cut away to reveal the space below. Useful for relating the separate drawings back to the building.

02 / In plan

Horizontal scan slice

A narrow band through the cloud reveals the returns at one height. It gives the drawing process a visible source to check against, including gaps and obstructions.

03 / Through the space

Section study

A vertical cut puts floor, structure and overhead returns in the same view. It helps explain relationships that a plan alone can miss.

Overhead-height study

A grid of observed overhead returns makes changes in height easier to see. Blank areas remain blank; this study does not establish minimum clearances.

Check the original plan

Do the columns line up?

A scan-to-plan comparison shows where the recorded column positions differ. Checking the alignment helps separate a global shift from a local discrepancy.

An original GA extract highlights column A with 591 mm remaining offset and column B with 88 mm after the global fit

The difference that remains.

In this example, fitting 13 shared column positions removes a 0.566° rotation trend. The median remaining offset is 54 mm.

591 mmstill separates column A’s recorded centres after that fit.

That is a focused check to take back to the original plan and the site. The alignment and column identification still need review before calling it a design or construction error.

Open the comparison

Grey linework and crosses come from the original GA. Orange points show the observed column centres after fitting the shared positions. This is a review study, not an approved setting-out check.

A simple sample viewer. Project drawings and source files remain in their project spaces.

The working approach

From capture to a useful record.

  1. 01

    Keep the source.

    The captured points provide the reference. Study views can be revisited as the project raises new questions.

  2. 02

    Make the evidence readable.

    Plans, sections and height studies isolate different parts of the scan. Interpretation and areas needing a check belong alongside the drawing.

  3. 03

    Bring it together.

    The project viewer brings drawings, scan views and supporting files into one place for review, with revisions and limitations kept visible.
