Case Study: Brisbane City Council accelerates tunnel resumption surveying with 12d Solutions

Brisbane City Council - Customer Case Study

The Brisbane City Council faced a significant challenge in acquiring the volumetric land parcels required for three major tunnelling projects (CLEM7, Legacy Way, and Airport Link). The process for calculating hundreds of complex underground lots for land resumption was manual, risky due to potential delays, and needed to be consistently repeatable to be legally defensible. 12d Solutions addressed this by developing a custom macro for use within the 12d Model software.

The solution from 12d Solutions automated the calculation of intersections between tunnel envelopes and surface lots, generating all necessary survey data in minutes. This custom macro ensured consistent, reproducible results and allowed for easy management of multiple survey suppliers. The innovation delivered the required information well ahead of schedule and proved its flexibility when a project change necessitated a full recalculation with minimal delay, significantly de-risking the entire land resumption process for the council.
