“The Pacific Highway upgrade is one of the largest road infrastructure projects in NSW. It connects Sydney and Brisbane, and is a major contributor to Australia’s economic activity”.

As we prepare for our latest ground improvement works utilizing Controlled Modulus Columns (CMC) at Lisarow to Ourimbah, we take the chance to reflect on the many projects we have already completed in delivering the largest road infrastructure projects in NSW over the last few years:
BALLINA BYPASS – 2006
The Ballina Bypass is a 12 kilometre long section of the Pacific Highway upgrade running between the Bruxner Highway and the existing Highway at Tintenbar, north of Ross Lane.
For this project, The Menard Vacuum Consolidation technique was chosen as the ideal solution to produce the required soil consolidation within a reduced time with no risk of the embankment instability, additional project costs or delay in program.
This project was the first of its kind in Australia to embrace the Menard Vacuum Consolidation technology and has shown to be highly successful in Ballina soft soil conditions.
KEMPSEY BYPASS – 2011
The Kempsey Bypass Alliance scope of works included the design and construction of 14.5 km of four-lane divided highway from Kempsey to Frederickton.
The project had to be constructed on soft soils with settlement characteristics. To minimise the effect of settlement, Menard Oceania constructed 875 numbers CMC 450mm diameter piles to depths of between 7 and 11 metres.
NAMBUCCA HEADS TO URUNGA – 2014
Menard Oceania took on the task of ground improvement for 2 new bridges to be built crossing the Kalang River and Deep Creek in NSW.
As the works were close to the rivers, an environmentally-friendly technique was required. CMC is a method that generates minimal spoil which was well fitted to the challenge at hand. A total of 1640 numbers CMCs were installed over the 4 abutments.
OXLEY HIGHWAY – 2015
This section passing Port Macquarie included a major bridge structure over the Hastings River. Menard Oceania was engaged by Lend Lease to install Controlled Modulus Columns (CMC) as part of the soft soil treatment on the northern approach to the new bridge.
10,500 lm was installed using one rig with an average depth of 19m as well as more than 1,700 cum of concrete.
TUGGERAH INTERSECTION UPGRADE – 2016
Menard Oceania was awarded the design and construct contract by SWC on behalf of RMS to provide CMC ground improvement works to enable the widening of the intersection approaches to accommodate extra lanes and construction of approximately one kilometres of retaining walls. More than 500 columns were installed.
COMING NEXT: LISAROW TO OURIMBAH – utilizing CMC technique
“We are proud to have the opportunity to help deliver such an important infrastructure project for Australia” said Philippe Vincent, Managing Director of Menard Oceania.
We would like to thank all the companies we have had the pleasure of working with in delivering these ground improvement solutions and look forward to more opportunities to support this great project.
