McMahon Services lifts crane award

At the recent CICA (Crane Industry Council of Australia) national conference held in Perth, McMahon Services was awarded the main award for Category A – Lift of the year for cranes over 130 tonnes.

The accolade was given in recognition for our performance on the Adelaide Convention Centre Redevelopment Stage two project. The project was based around the deconstruction of the 1987 built Convention Hall called the Plenary Building, to make way for new construction, which forms part of the $350 million Riverside Precinct Upgrade.

During a six-month intensive planning phase, a deconstruction process using cranage was identified as:

  • The best method to minimise disturbance to stakeholders
  • The best way to reduce risks associated with uncontrolled collapsing
  • The best method to maintain integrity of the suspended plaza slab

The scope of works for the deconstruction lifts included the following:

  • Pre-planning, engineering and scheduling
  • Internal strip out of all interior linings, operable walls, insulation, seating, and glazing
  • Removal of roof sheeting and multiple acoustic insulation layers (compressed straw panels)
  • Removal of all perimeter precast wall panels
  • Removal of all secondary structural members
  • Removal of all mechanical plant (air handling units) from high level plant rooms
  • Removal of all external primary structural steel
  • Removal of high level precast concrete cladding
  • Removal of floor slabs from plant rooms
  • Removal of main box truss structures
  • Removal of remaining tower floor slabs
  • Removal of northern lift shaft

The delivery of this project required over 5,000 crane lifts, and at its peak McMahon Services had five cranes operating in the same vicinity, on the suspended slab with very limited access.

Key Highlights
  • Over 5,000 individual crane lifts
  • 4,620 crane hours
  • 49,050 man hours
  • No lost time injuries
  • Incident free
