Project Information
On the corner of Gilmore Road and McPhee Drive in Berrinba, ESR are developing new, high-end office spaces and warehousing. With the ground level entrance coming off McPhee Drive, the adjacent car park area rises to meet the upper-level offices. To retain land for new car parks, ESR required a vertical retaining wall solution that could be placed as close to the new warehouse structure as possible and could be built around concrete piling installed for the causeway entering the office area from the carpark above.
DESIGN
Approximately 150m long and retained to a maximum height of 7.5m, a staggered MagnumStone wall was designed to take the carpark area traffic loading as it rose from McPhee Drive. The design used a combination of extender lengths to support the height variations as the wall extended up the slope. The exibility of MagnumStone’s design also allowed for a recessed section within the wall, curving approximately 1m into the cut face to bend around the concrete piling.
INSTALLATION
Construction of the retaining wall and warehouse occurred simultaneously on a tight site. After clearing the cut face and creating a at platform, the bottom layer of MagnumStone blocks was precisely positioned. Small excavators lifted and placed the blocks and extenders. Site fill was used behind the wall, reducing material needs, with the retained land usable once compacted and tested. The blocks were filled with drainage aggregate, and concrete was poured into the upper layer to allow for a handrail. MagnumStone’s versatile design solutions and speed of installation meant this aesthetically pleasing, vertical retaining wall solution allowed construction of the new warehouse, office space and carpark area to continue with minimal disruption.
The MagnumStone system provided the following benefits to the project:
- Versatile design solutions with quick and easy installation
- Able to use site fill behind the wall
- The MagnumStone Gravity Extender System was used to minimise site cut.
- An ascetically pleasing retaining wall system.
