North Fremantle PSP
Project Overview: Undertaking the construction of a 2km-long, 4.6m-wide red asphalt Principal Shared Path (PSP) from Victoria Street to North Fremantle train station, with concurrent modifications to Curtin Ave to facilitate safe pedestrian crossings, presented a multifaceted endeavor. Key project components encompassed:
- Adhering to strict safety measures near the operational electrified railway, necessitating the formulation and execution of a comprehensive Rail Safety Management Plan, alongside the installation of 1.8km of temporary General Exemption Fencing.
- Collaboration with various authorities, including the City of Fremantle, Town of Mosman Park, Town of Cottesloe, Main Roads WA, and the Public Transport Authority, to navigate regulatory constraints.
- Coordination with multiple on-site contractors, such as Western Power for street lighting and underground power installation, Venture Smart for signalized pedestrian crossing modifications, and other entities utilizing Leighton Yard as a materials compound during construction.
- Development and execution of a sophisticated Traffic Management Plan accommodating day and night works, school zones, signalized pedestrian crossings, and spanning three distinct local government jurisdictions.
- Undertaking vegetation clearing spanning 1.3 hectares, coupled with responsible disposal of contaminated materials, including asbestos.
- Execution of bulk earthworks and embankment construction involving 12,000 cubic meters of material.
- Construction of the PSP pavement, incorporating crushed rock base materials and laying 10,000 square meters of 25mm lateritic red asphalt.
- Implementation of various concrete elements, such as stairs and a protective slab over an obsolete PTA tunnel.
- Pavement construction for road widening on Curtin Ave spanning 1150 square meters.
- Installation of diverse drainage structures, including pits, gully grates, cycle-safe wave grates, high-flow catch pits, concrete culverts, headwalls, and infiltration trench drainage.
- Mortared stone pitching for spoon drains, drainage structures, and V-drains.
- Kerbing installation, encompassing barrier, semi-barrier, semi-mountable, and mountable kerb types.
- Pram ramp installations, featuring tactile indicators and grab rails.
- Installation of a new Main Roads Western Australia (MRWA) lighting circuit switchboard and cabinet, with connection to Western Power mains.
- Installation of 67 PSP lighting poles and luminaires, reaching a height of 7m.
- Erection of 360m of 1.4m-high cycle-safe balustrade and 200m of 1.0m-high handrails for disabled access.
- Construction of 2km of 1.8m-high, triple-barb security fencing to PTA standards, inclusive of gates and isolation panels.
- Resurfacing of Curtin Ave over 8250 square meters, involving profiling and 30mm Dense Graded Asphalt (DGA).
- Construction of road widenings for median islands, pedestrian walkthroughs, and median island removal for road realignment, including 1500 square meters of 220mm deep full-depth asphalt pavement construction.
- Installation of 67m of W-beam safety barrier, complete with an ET-2000 end terminal.
- Application of line markings to the PSP and Curtin Ave, featuring thermoplastics, lines, and raised pavement markers.
- Preliminary landscaping works, encompassing topsoil, mulch, and hydro-mulch.
Advanteering maintained ongoing communication with the client and the designer, actively identifying challenges and proposing alternative solutions throughout the project's duration. This collaborative approach resulted in the successful completion of the project approximately $1 million under budget and ahead of schedule.
