As part of the NorthConnex government mega project to link the M1 Pacific Motorway at Wahroonga to the Hills M2 Motorway at West Pennant Hills, integration work was essential along the Hills M2 Motorway. NEPEAN Engineering and Innovation were awarded the subcontract for structural steel works through project Builder LLBJV in Mid-2018. The specifications included the detailing, supply, fabrication and installation of the HS01 Substation & Southern Vent Facility.

The building at the southern ventilation facility consisted of steel framing, structural beams and metal decking, in addition to the structural steel works for the substation at Coral tree Drive. All access platforms, stairs, handrail and gratings were included under NEPEAN Engineering and Innovation scope of works.

NEPEAN Engineering and Innovation works extended in the project to include the supply, fabrication and installation of the maintenance facility’s covered service yard steel structure works.

The project required approximately 300 Tonnes of steel and NEPEAN Engineering and Innovation successfully overcame the challenges that related to project logistics, design development and tight scheduling to deliver the project successfully.
