Sydney Airport RESA (Runway End Safety Area) project has won the infrastructure projects award at the NSW Engineering Excellence Awards in Sydney. Construction of the 90 x 90 m2 cleared and paved safety area at the western end of the east-west runway (07/25) was a significant engineering challenge as it had to be built over a major heritage listed sewerage line, the M5 East Motorway tunnel, and a major electricity cable.
Menard Bachy was awarded the challenging task of constructing the double purpose retaining and cut-off wall system a and sufficiently improving the ground for supporting the formworks and struts using jet grouting. Murray Yates, the successful project manager of the project, has recently been transferred to GFWA. Babak Hamidi has made a presentation of the project in Perth’s Ground Improvement Workshop held on 11 and 12 June 2010. The paper co-authored by Murray and a number of other Menard Bachy engineers has been published in the December 2010 issue of Australian Geomechanics Journal.
