This project is an expansion of the Ausgrid’s Macquarie Park Substation, a $7M facility that Haslin proudly delivered in 2020. The original project involved the construction of a 132/33kV step-down sub-transmission station in order to meet Macquarie Park’s growing power requirements, while this 2024/25 scope expands the substation with a third 132/33kV transformer.

The scope of work included the demolition of the existing oil containment systems, retaining wall, and sewer line, plus the removal of steel frames as required. The new bay work involves complex geotechnical and structural temporary works (including design co-ordination), form/reo/pour, precast wall segments, an oil containment system, low voltage system, structural steelwork and HV cable pulling.

Once Haslin completed the oil containment system and transformer bay, preparation and excavation of the 33kV and 132kV cables was undertaken. Then, low voltage works began and new distribution boards and circuits between the transformers were delivered. Finally, footings and finishing electrical works were undertaken, along with installation of proper signage and making good of driveway / yard alterations.

In order to exceed Ausgrid’s expectations on this project, Haslin drove a number of innovations including a crucial redesign of the temporary works, design development of the ground floor slab penetrations and unique management of complex crane lifts.
