Diversi’s infrastructure engineering experience ranges from roads, rail works, mass transit, light rail, mining sites and bridges to water management, hydraulics and wastewater treatment. Services include civil engineering, structural, hydraulic, electrical engineering design, water management and more.

Sydney Rapid Transit Stabling Yard Rouse Hill

Transport for NSW (TfNSW) proposes to develop a Rapid Transit Rail Facility on land between Tallawong Road, Schofields Road and First Ponds Creek in the localities of Rouse Hill and Schofields.  The Rapid Transit Rail Facility will comprise a purpose-built train stabling and maintenance facility to support Sydney’s new rapid transit rail network.

Diversi Consulting has been engaged by JBA and Transport NSW to prepare a report on the availability of services in the area for the Rapid Transit Rail Facility (RTRF) at Tallawong Road, Schofields. Diversi also defined what utility service lead-in works are required to adequately service this facility.

This now forms part of the Sydney Metropolitan Rail Link.

Mount Piper Area Coal Mine Haul Road

Due to a planned expansion of coal mining operations in the area, the mine operator proposed the construction of a new 1.5km long haul road linking the mine to a new coal wash facility. The road comprised a 10m wide rural road to carry B-doubles, carrying up to 5 million tonnes per year. The route of the haul road is a complex route constrained by existing mine storage/ treatment dams, creeks, a highway, floodplain and a future coal freight rail link.

Diversi Consulting were engaged to evaluate two route options including the concept design of each road option. This involved an evaluation of the stormwater drainage, flood assessments (for a 20km2 catchment), weir and spillway requirements for each of the three large dams (150ML to 500ML). The concept designs also included bridges, up to 120m long, and the major culverts over the highway, floodplain and local roads.

As a result of the engagement, Diversi Consulting was able to optimise a preferred route which minimised earthworks; future operational noise on the local community; minimised works on existing dams and reduced the length and size of the bridge and culverts required.

Sydney Light Rail – Enabling Works – Moore Park Tennis Centre

Diversi Consulting were engaged by Laing O’Rourke to design some of the enabling works for the new Sydney Light Rail (SLR) project. One of the 12 sub-projects for the enabling works was the Moore Park Tennis Centre. This design work was to allow for the new light rail route along Anzac Parade, so it was therefore necessary to relocate the Moore Park Tennis Centre car park and the adjacent netball complex amenities building.

The carpark works included: earthworks, stormwater drainage pits & pipes, new pavements (some consisting of permeable pavements), footpaths and disabled parking. Diversi were also engaged to design the retaining walls, kerb and gutters, lines/signs, lighting, new trunk stormwater drainage culverts and fences.

The amenities building comprised a single storey brick building, steel frames, with a concrete raft slab on piers standing over the existing trunk drainage culverts. The building design included change rooms, office, store room, canteen and utilities.

Diversi Consulting provided civil, structural, hydraulic and electrical engineering design services for the works. By providing a comprehensive design solution, Diversi were able to provide the design in a tight timeframe and work with the difficult site constraints to further minimise the structural elements. Diversi customised the building design to be constructed over and around the existing trunk stormwater culverts (which were heritage listed) and build over the uncontrolled fill in the area.
