Arcadia Estate, Officer

Spiire’ Civil and Water Engineering teams were engaged by Satterley Property Group to undertake engineering services for the masterplanned Arcadia Estate development in Officer. The development incorporates 25Ha of open space including a number or waterways and wetland as well as arterial roads, signalised intersections, South East Water shared assets and a range of townhouses and conventional residential lots.

The scope included the delivery of the Officer South Drain, a major constructed waterway with an upstream catchment of approximately 800Ha. The Melbourne Water Drainage Scheme also required Spiire to deliver a second constructed waterway, a sediment pond, a complex network of Melbourne Water major drainage and two culverts crossings.

Due to out of sequence development in the Officer area there were a number of complexities in designing and constructing an outfall to allow flood water conveyance to Cardinia Creek. The Spiire team worked closely with Melbourne Water, VicRoads and a number of other stakeholders to enable a long-term interim design solution to mitigate flooding downstream rural properties and degrading the existing waterways.

Further challenges were faced during the development of an environmental management and construction plan and then during construction of the major 75m wide waterway. With such a large upstream catchment and high water table, the management of surface and groundwater was critical. Spiire’s close working relationship with the geotechnical engineer and the civil contractor has been pivotal to developing options to dewater and divert flows to enable construction to proceed.

Spiire’s Civil Engineering and Water Engineering teams also worked together to were engaged by provide detailed design for a 1500m reconstruction of Officer South Road. This reconstructed road will form a main thoroughfare through the Arcadia Estate development, enable direct access to the Monash Freeway, and is a Council and VicRoads requisite for the Estate.

Currently an existing road reserve which runs through the centre of the greenfield development, the road has been designed as a major dual carriage way arterial with the inclusion of two signalised intersections. Located in a large drainage catchment area, our Water Engineering team’s design includes culverts that cross over Officer South Road. Our team have also designed 300 meters of drainage which, in parts, measures up to a substantial 2.4 meters in diameter.

Our team have been busy as the lead consultant on the project which has involved significant coordination of services including the relocation of Telstra NBN, relocation of gas main and watermains 300mm in diameter. Working closely with the electrical consultants, our team have also coordinated the relocation of all underground and overhead electrical infrastructure along the existing road reserve.

This is a challenging project which utilised the collective expertise of our diverse Engineering team to deliver excellent outcomes for the local community. This project not only involved the upgrade to 1500 meters of the existing unsealed road to a dual carriage way arterial with signalised intersections, but also integrated critical South East Water assets and Melbourne Water main drainage infrastructure.

The Arcadia Estate is an excellent example of our integrated Civil and Water Engineering teams  collaborating to deliver a masterplanned community in the Cardinia growth corridor.
