Abergeldie has been awarded a contract to design and construct an underpass for pedestrians beneath the rail corridor within the new Site 3 Pocket Park at Sydney Olympic Park. The new underpass will link Pocket Park and the boundary of Site 68 (a development that is being undertaken separately by the Principal).
Construction involves excavation through the rail embankment to allow installation of the box culvert section, terracing, retaining walls, paving, seating and street furniture, lighting, gabion wall cladding, handrails and stormwater drainage. Park landscaping will include new and transplanted large trees, with an irrigation system operated from a centralised time control system.
The installation of the precast concrete box culvert will be carried out during a 72hr rail possession. Timing will be critical, with each step of the works programmed on an hour by hour basis, to avoid late hand back of the rail corridor which must be reopened for trains early the following morning. A lifting and skidding system will be used to jack up and slide precast culvert into place.
