All piling works completed within scheduled programme and rail occupation deadlines.
The removal of Mountain Hwy and Scoresby Rd level crossings was highlighted as an early priority for the Victorian State Government as part of their commitment to remove 50 of their most dangerous level crossings. Keller were engaged early in the planning stages to assist LORFHJV in the delivery of nearly 800No. x 900mm and 1050mm diameter bored piles for retention walls and bridge abutment foundations. Piles were between 18m to 24m deep.
Rail corridor work adjacent to live running rail always presents numerous safety, logistic and programming challenges. Many areas required weekend or short term rail occupations with 24/7 works and multiple rigs to ensure full advantage of the trains being taken offline. Heavy reinforcement cages were required to be safely installed next to live rail and, in some areas, in less than 10m head height restrictions under live overhead services.
Close liaison and co-operation with the client was required to program works around the predetermined rail occupations. The Mait 130 Limited Head Room setup allowed 900mm diameter piles, up to 18.0m deep, to be constructed under live power.
