F11 Hunter Expressway
New South Wales, Australia
The project consisted of three twin viaducts of 196m, 254m and 329m lengths, built using a total of 560 precast segments.
Detailed models were created of each bridge using ABES geoDes.
Construction tolerances were extremely tight and ABES geoCon was used to ensure that segments were cast to the correct alignment.
ABES geoCon was able to support use of a robotic total station survey allowing three casting cells to be surveyed from a single instrument operated by one person.
The project was delivered successfully in 2012 by a consortium with VSL being responsible for geometry control and relying on ABES Software.
