Scope comprised fabrication and installation of a shelter canopy over the railway station’s central platform, underground substructures and service connections. The canopy was fabricated and partially pre-assembled off-site at the Regents Park Workshop of Abergeldie Structural Fabrications to minimise the duration of disruption to customer’s normal access to the station platform. Most works were carried out while the station remained open to customers, but some elements of scope could only be completed during weekend rail possession periods. Rail safe working requirements were strictly observed, with a rail Protection Officer in attendance for all on-site works.

Abergeldie delivered a package of works for ARTC across a number of track recon sites throughout the Hunter Valley. Scope involved the removal, reconditioning and replacement of existing rail track on the Ulan Line and Main North Line during rail possessions. Track was subsequently tamped utilising track resurfacing machines and welded. Total length of track work completed was 700 metres across 6 possessions. Packages were completed at Bengalla, Coggan Creek, Sandy Hollow, Scone and Wilpinjong.

Works were completed around the clock, with teams of over 100 personnel onsite during the possessions. Work locations were constrained by tight access.

Part of the Transport Access Program, this is a design and construct project to improve access for customers and deliver modern and secure transport infrastructure.

The scope of work included construction of three lift wells and installation of passenger lifts, a new electrical substation, electrical conduit connections beneath the rail corridor, upgrades to stairs, ramps and subways, signage, lighting, new rain shelters and amenities on all four platforms.

Innovation

Some works on the station platforms, at the station entrance and in the pedestrian tunnels beneath the tracks were carried out while the station remained open to the public. These elements were carefully staged to minimise disruption and maintain public safety.

The electrical demand of the new lifts required a new substation, with conduit connections installed by directional drilling, passing under the rail tracks.

Other works, such as excavation and piling for construction of the lift wells, could only be carried out during weekend rail possession periods within strictly pre-determined time windows.  Programming of works during possession periods was planned in hour by hour detail, with two shift teams working around the clock.

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.

PROJECT DESCRIPTION:

Sydney Trains awarded this project which involved the installation a 40m single span RSJ –composite deck, four lane bridge, 11kv Ausgrid and 750mm Water Main service relocation, road approaches, temporary retaining wall design and construction, bridge demolition works, overhead wiring construction works and other site finishing works. Some of the works involved working within the rail corridor which involved precisely planned rail track possession dates. Construction was carried out in stages.

PROJECT DESCRIPTION:

Transport for NSW awarded a contract to Abergeldie in November 2014 for the design and construction work to convert rail staff parking spaces into commuter parking spaces at 30 locations across the NSW network. (VIDEO SUPPLIED BY TfNSW).

The scope of work varied at each location across the 30 sites, with some sites involving the conversion of as little as six and others with as many as 70 commuter parking spaces. Where possible, Abergeldie managed the staging of construction to enable customers’ use of parking spaces during construction activities. During the project Abergeldie established and maintained relationships with multiple community groups, including bus operators and railway operations teams. Works were delivered under the NSW Government’s Transport Access Program.

PROJECT DESCRIPTION:

Abergeldie was awarded the contract to construct a 430m long 5m high reinforced concrete retaining wall for Queensland Rail as part of their $4.4billion New Generation Rolling Stock Project.

The contract required excavation and retention of an earth batter to provide additional access for the new railway bypass line into the facility. One major risk of the project was a high pressure gas main buried within the batter which was at risk of collapse during excavation. Abergeldie safely installed bored piers to support the gas main prior to constructing the wall.
