Value Engineering Solution
  • Proposed alternative flexible unbound granular pavement in lieu of MRWA specified full depth asphalt pavement for the freeway component of the works.
  • Increasing the slope of the earthen embankments by using geofabric stabilization removing the need for stone pitched embankments and limestone retaining walls resulting in reduced earthworks and infrastructure in the freeway road reserve.
Unique Design Items
  • Design of the proposed underpass box culverts to AS 5100 for bridge loads and the footings/tie beams for the large retaining/surcharge loads.
  • Design of the crash barriers over the proposed underpass box culverts to Main Roads WA specifications.
  • Proposed use of inverted precast box culverts in the areas with larger retaining heights to expedite construction in the deeper excavations.
  • 2016 Master Builders WA - Winner, Best Retail Building (Awarded to Perkins Builders)

A first for Western Australia, BP opened two state of the art travel centres at Baldivis South and North and are expected to service approximately 9,000 customers daily.

The 10 hectare greenfield sites located on each side of the Kwinana Freeway between Mundijong and Safety Bay roads are each equipped with 39 fuelling stations and host McDonald’s, Red Rooster and BP’s Wild Bean Café with seating for 150. The sites offer a children’s play area, garden area with a BBQ, ATM facilities and a lounge for truck drivers. The sites provide parking for 10 b-double truck bays, three coach bays, three caravan bays and more than 100 car bays, BP Baldivis North also caters for cyclists providing access to the freeway dual use path and bicyclist facilities.

In another first for Western Australia, design and construction of the freeway on and off ramps were undertaken by a private developer under agreement with Main Roads Western Australia (MRWA).

Pritchard Francis undertook the civil and structural engineering works for the two travel centres and adjacent car and truck refuel canopies. In addition, the Pritchard Francis team acted as lead consultant for all the civil engineering aspects of the north bound and south bound freeway entry and exit ramps to MRWA requirements.

Close liaison with MRWA and Perkins on the design aspects of the works enabled key items to be identified and resolved early in the design process. Items that were resolved included consideration of alternative design options to reduce construction time and cost.

The project including both sites and freeway works were completed within 12 months and opened simultaneously to the public on the December 9, 2015.
