Gold Coast Rapid Transit
Project Summary
The Gold Coast Rapid Transit (GCRT) is a
major infrastructure project that aims to integrate new and existing transport
systems, support urban regeneration and facilitate sustainable transit-oriented
development.
The GCRT Project comprises a 13km light rail system between the
Gold Coast University Hospital on Parklands Drive in Southport and the
Broadbeach South Station adjacent to Pacific Fair Shopping Centre. The Project
brings together the world’s best infrastructure and urban design solutions to
create a vibrant and bold future for the City.
Cardno’s involvement with the
GCRT Project has been to provide consulting services in regard to underground
utilities, landscape architecture and urban design, building structures,
building services, building certification, way finding and temporary traffic
management planning.
The Challenge
The major 12d task undertaken by Cardno on the GCRT Project was the assessment
of existing underground utilities and space-proofing of proposed and relocated
utilities. Accurate underground utilities records are rare. Records are usually
incorrect, incomplete, or inadequate.
Cardno was faced with the challenge of coordinating a variety of survey data,
identify existing utilities that clash with the proposed track alignment, and
provide design solutions for the protection or relocation of these utilities.
This included allocation of corridors for utility owners to commence detailed
design.
The Solution
Incoming field data was assessed and re-modelled where accuracy was lacking. The
field survey data was received in strings & points format. Cardno designers
converted these raw strings into 3d pipe & conduit super strings. Where field
data was not provided, gaps were interpolated or extrapolated to provide a
completed model.
Existing underground
manholes and pits are traditionally surveyed with a point to represent the
structure. To provide a complete existing model, manhole extents and pits sizes
were also surveyed and then accurately modelled.
By utilising the developed 12d model, clashes with the track alignment were
easily identified which enabled the Cardno team to allocate corridors for the
various utility owners.
The Result
The result is an interactive 12d model containing the proposed track, all known
services and proposed service corridors along the construction route.
