BBR Contech has recently installed a self-monitoring cathodic protection system on Dunedin’s Kaikoura Estuary Bridge – an important commuter link between the city and the coastal community of Brighton.
Thought to be the first building in New Zealand to use PRESSS technology for a steel structure, the Centre is being built using four pairs of structural steel frames, each vertically post-tensioned to the foundations with unbonded, high-strength steel bars. The frames are able to rock during earthquakes, with the post-tensioning providing a restoring force to help the building to return to centre.
Failure of epoxy linings were identified within newly built sewage wet well pumping structures, located on the foreshore of McLeod’s Bay. These structures service both gravity reticulated and pumped raw sewage from the residential catchments of McLeod’s and Urquhart’s Bay on the Whangarei Headlands.
The effects of heavy transport on a critical bridge linking Hawke’s Bay with points north and south led to a significant FRP strengthening project for BBR Contech.
