Tench Reserve Project
Construction of a multilane boat ramp, trailer parking and associated infrastructure at Tench Reserve, Jamisontown (Penrith) has recently completed. These works form part of a wider masterplan for the banks of the Nepean River, funded jointly by the Australian Government and the NSW Boating Now Infrastructure Program.
New access roads, 10 new vehicle parking bays, jetties along the foreshore (including connection to the existing jetty), footpaths, stairs, balustrades, fencing, landscaping and lighting were also included in the upgrade.
Tench Reserve is located on the southern bank of the Nepean River, directly adjacent (and under) the M4 overpass. Northrop worked alongside Penrith City Council and Clouston Associates from concept phase through to completion to overcome complex site topography, hydrology and geology to deliver a cost effective, considered design.
A collaborative approach was taken to foster ongoing and regular involvement from the wider project team (geotechnical engineer and contractor) during the evolution of the overall civil design. This allowed the site earthworks and stormwater management strategy to be optimised, with a focus on cost and constructability.
With retaining wall heights exceeding 5m, the team delivered a compliant 34 space trailer parking facility on the side of a steep embankment (1:4) in a flood effected area on soils with extremely poor bearing capacity. Not only was the constructed design robust, it also met the desired aesthetic outcome envisaged at the project outset.
