Lachlans Line, Macquarie Park

The project is located on a 12ha site at the corner of Epping and Dehli Roads, North Ryde.

The project involves the subdivision of the site, up to approximately 2,000 dwellings in high density / mix use development, with central park, retail precinct and bus interchange for the railway station.

Diversi were engaged by Christie Civil and Urban Growth NSW for the design of the civil infrastructure works including bulk earthworks, site works (including all roads, stormwater drainage, trunk drainage culverts and creek works as well as lines, signs and services coordination), Wicks Road intersection (including new traffic signals, service modifications, new stormwater drainage and pavement works) and Epping Road works (comprising a deceleration lane, pavements, stormwater drainage and services relocations).

The project has been complex and often challenging given the flooding and services in Wicks Road as well as the tight design and construction program. However, Diversi were able to meet the tight programme and provided valuable design of the trunk stormwater system in order to reduce construction costs and flooding to Wicks Road. In addition Diversi were able to provide a creative solution to the design of the stormwater drainage system in Wicks Roads due to the extensive number of services constraining the works.
