The Casey 2 Estate (Springbank Rise) was a highly successful development for Lend Lease Communities. It comprises of around 1,200 residential lots, a commercial area for a local centre and leisure facilities, and large ornamental ponds/ wetlands which provide a key landscape feature and the water quality control facility for the estate..
Indesco was given the opportunity to work with Lendlease communities to develop this truly first-class estate where the recreation, community facilities
and environmental protections were high on the desirable outcome list. In addition to the residential estate the project also included a bulk water supply
pump station and rising main. Indesco was engaged to undertake the masterplanning for the entire estate.
Design challenges included stormwater drainage management to divide a major flow path to a manageable magnitude thereby reducing flood risk
and infrastructure cost. Further challenges included creating centrepiece ponds and wetlands with low maintenance WSUD features, an interface with remnant bushland to the west, a bulk supply water main through the estate and staging to deliver 1,200 lots within the clients program.
Tree retention and efficient earthwork management between stages demanded a high level of design management and bulk earthwork master planning. Critical infrastructure and accesses were constrained from opposite directions, requiring careful detailed design planning to avoid abortive or temporary work.
On completion of the masterplanning, Indesco was engaged to prepare the EDPs and detailed design for each stage. We provided engineering services for a multi-disciplinary design team. The client utilised in-house project managers and urban designers. Indesco worked collaboratively with the design team and other key sub-consultants.
Subsequently, Indesco was further engaged to provide contract administration and construction surveillance services across all stages during the progressive rollout of the estate. This resulted in an ongoing involvement on the project for over 5 years.
Particular challenges on this project included steep terrain and large quantities of rock which required blasting and crushing to incorporate within the works. Also included significant challenges with other ground conditions such as slope wash, ground water and unsuitable materials. Ongoing co-ordination was also required throughout the project with ICON water for construction around their bulk watermain which ran through the estate.
