A key element of the Tomakin Sewage Treatment Plant project is the development of a comprehensive 3D model that encompasses the existing features of the site and the proposed underground infrastructures and underground utilities such as stormwater drainage, water, and electrical systems. NSWPW is now applying this digital methodology to similar projects, improving outcomes and efficiencies.

Background

The existing Tomakin Sewage Scheme serves the urban communities of Rosedale, Guerilla Bay, Mogo, Tomakin, Mossy Point, and Broulee located south of Batemans Bay.

Currently, sewage collected within the gravity and pressure  sewer catchments is pumped to the Tomakin Sewage Treatment Plant (STP). In preparation of urban zone expansion, augmentation of the scheme is being planned to allow for the future sewage loads.

This ensures the STP’s treatment capacity is sufficient to accommodate present and expected future loads, while producing effluent that will meet regulatory requirements.

Key project facts

  • Developed 3D models that can produce construction drawings and provide inputs for further engineering analyses.
  • Identified potential design clashes prior to the commencement of construction.
  • Enhances the likelihood of completing the project within the allocated budget and schedule.

Our role

NSW Public Works (NSWPW) were engaged to  develop an upgrade concept for the Tomakin STP which will form the basis of subsequent detailed design and construction documentation.

In support of NSWPW’s Water Resources  Management group, the Digital Engineering (DE) team spearheaded the 3D modelling effort required for the Tomakin STP augmentation works.

This involved developing 3D models of existing features, proposed buildings, surrounding civil works, and underground pipelines such as storm water drainage, water, sewer, and electrical.

The overall project was delivered via a cloud-based common data environment platform managed by  the NSWPW DE team.

Outcomes

The result is a federated 3D model which allows designers to identify potential clashes between existing and proposed assets prior to the construction phase. The federated model also creates realistic visualisations that enable stakeholders’ participation during the design development phase.

The STP augmentation design work is currently at 75% detailed design. The goal is to achieve a clash-free federated model (Level of Details 300)
at 100% detailed design stage.

Integration of survey outputs, such as point clouds, into engineering workflows was also made possible with the help of common data environment which streamlines the data exchange processes between teams.

Having access to the latest digital tools and  familiarity to digital delivery practices bring the dispersed NSWPW teams across the 4 regional offices together to collaborate effectively.
