Hansen Yuncken partnered with Downer to construct nine buildings at the Pakenham Train Maintenance Facility. The project is part of the $2.3b High Capacity Metro Trains Project PPP, with these buildings providing ancillary support for the upkeep, maintenance and operation of 65 trains. At 160 metres in length, each train comprises seven carriages and has capacity for up to 1,100 passengers. Completion of this project significantly increased capacity of the Cranbourne-Packenham train line.
The Packenham site resembled a teardrop shape (over two kilometres long by one kilometre wide) and the nine buildings (approximately 25,000m2 under roof) were widely dispersed across the large project site. The project delivered the largest extension to the rail system in Melbourne in over 50 years, and consisted of Integrated Testing, Maintenance, Bio-Washing and other specialist buildings.
The contract included the delivery of buildings, Integrated services and fitout as well as significant coordination and integration with specialist contractors involved with the rail infrastructure delivery.
