Menard Oceania has recently completed ground stabilization works to support Seymour Whyte’s project on the International Terminal - Project 2C.
The works consisted in a campaign of jet grouting to provide lateral restraint to a sheet pile wall located adjacent to the RMS owned Giovanni Brunetti Bridge.
The jet grout plug spans an approximate area of 13m long by 7.5m wide. Our team installed a total of 42 columns at 1m to 1.5m deep.
This project brought us back to good memories from almost 7 years ago, when we were completing one of our biggest jet grouting job for Sydney Airport (Runway End Safety Area project), installing 5,600 lm of columns.
Menard secondly installed a mini pile solution that provided an alternate to typical large diameter piling; in conjunction with a wider piling package successfully delivered by its sister company AFS Bachy Soletanche. The final solution consisted in 8No. 25m deep & 275mm diameter piles in a restrained headroom of 4m utilising one of our 12t rigs. Quite a good performance in such a confined space!
“The site location was another challenging aspect on this job, being just next to a pedestrian walking lane and about 30m from the Cook River: this meant that all spoil generated by drilling activities had to be minimal and contained” explains Tin Le, project manager at Menard Oceania.
The team successfully implemented a continuous enclosed recycling drilling fluid system which caused minimal impact to surrounding environment.
