PointBIM carried out a colour terrestrial laser scan of the historic front entrance to Colston Hall—now Bristol Beacon—to capture a reliable record of the façade, foyer threshold and immediate streetscape before refurbishment.

01

Project Scope

The client required a precise 3D record of the old entrance, including:

  • Principal façade, canopies, doors and steps
  • Foyer threshold and ticket-hall interface (as accessible)
  • Adjacent paving, kerbs and street furniture for context
    The aim was to fix existing geometry ahead of demolition/alteration and to support downstream modelling by others.

02

Our Approach

We completed a short, tightly sequenced scan programme outside public opening hours to minimise disruption. A small control network was established and checked; all scans were colourised and registered to a common project coordinate system. QA checks covered overlap, residuals and coverage, with a brief scan report issued alongside the data.

03

Deliverables

  • Unified registered, colour point cloud: RCP/RCS for Autodesk users and E57 exchange file
  • Project coordinate report and scan limits sketch
  • Basic clipping groups/view recommendations to speed up downstream modelling

Notes: This commission delivered point cloud only. The design team handled all post-processing/model build in their own software.
