SH20 to Airport, Manukau, Auckland - Platipus Anchors®
SH20A is the primary route to and from Auckland Airport and forms a strategic link between SH20 & SH16, the Airport Business District and the greater Auckland area. The NZ Transport Agency’s upgrade of SH20A to motorway standard has provided a safer, more reliable route to and from the airport and has increased freight efficiency around South Auckland.
Cirtex worked with FCC temporary works engineers to design working platforms over very weak ground conditions for the safe operation of heavy machinery. Cirtex also provided an alternative slope stability solution, saving significant time and money.
Two layers of SecuGrid® were used to reinforce the gravel raft providing efficient load distribution of the stresses transferred from the heavy plant and equipment. As an alternative to sheet piling Platipus® Anchors were used in conjunction with CombiGrid® to stabilise steep cuts.
The products used provided the following benefits to the project:
- Platipus provided an anchor system that was cost effective in comparison to other systems
- CombiGrid and Platipus anchors were chosen to stabilise steep cuts as they used readily available equipment for installation
- SecuGrid assisted in providing an efficient and safe working platform
