Waterloo Integrated Station Development

The Waterloo Integrated Station Development (ISD) includes the construction of the new Waterloo metro station and Waterloo Metro Quarter, which includes four buildings above and next to the station.

John Holland is constructing the new Waterloo Sydney Metro station, while a John Holland and Mirvac joint venture will develop and build the Waterloo Metro Quarter development.

Veris were engaged by John Holland to provide surveying services for both the metro station and over station development. This has included feature surveys of the site and surrounds, and subsequently the construction works of the Waterloo Station ISD.

Scope

The scope of services provided by Veris includes:

  • Feature surveys conducted by 3D laser scanner of the site and surrounds, including underground utilities, boundary and stratum.
  • Construction surveys for the Waterloo metro station, including the station box, services, station platforms and vertical supports
  • Monitoring surveys
  • Management of the survey process for the client
  • Survey works for various project activities.

Highlights

Upon taking possession of site, the client required a greater understanding of the station box to satisfy handover, contractual and design purposes. The critical items were the shore walls and the anchor bolt relationship to the MCO line.

Veris provided an innovative solution, using 3D scanning technology to capture all data within the station box area. The scans were then georeferenced to site datum, allowing a creation of a single point of truth.

Key deliverables and insights enabled by this approach included:

  • Updating of the design model and a dynamic digital twin in Revit showing all locations of the 1000+ bolts.
  • Providing a comparison works of protruding bolts vs MCO line and the cutting required as highlighted by red and green items and to then be shown in a visualisation timeline format for programming.
  • Developing heatmap comparisons showing shore wall vs MCO to understand grinding and infill for quantities.
  • Submission of station-box as-built in 3D BIM, using Navisworks, which can be combined with upcoming construction works to develop a single BIM model for the project and minimise Digital Engineering processing requirements.

As a result, from a single data capture exercise and offsite analysis we were able to supply a comprehensive understanding of the work that would need to be executed on site. The approach was a true innovation, through the application of Digital Engineering (DE) technology.

Veris provided a solution to a construction problem using scanning and modelling techniques, which has led to savings on programme and delivery. Instead of using a conventional method, which would have been more costly, it provided an approach that gave greater clarity on costs earlier and reduced programme risk, with an overall benefit of reduced safety risk for the project.
