Kaikoura SH1 Rebuild (NCTIR)
Reconnecting an earthquake stricken community.
HEB Construction is part of the NCTIR alliance and has been responsible for rebuilding and repairing several bridges damaged in the quake. These included the seven-span Irongate Bridge and six debris flow bridges (three road and three rail), Bridge 908 south of Ward, and the 480-metre rail bridge across the Clarence River.
Construction of the new bridges required 144 concrete bridge beams. Because of the time and supply constraints of the project, most of these beams were manufactured in the North Island – the majority – about 80 percent – from plants in Rotorua, Hastings, Christchurch and HEB’s plant in Mount Maunganui.
HEB transport was required to project manage the transport of the 144 concrete bridge beams with delivery of all 144 beams to occur over a 12-week period.
Protecting Kaikōura’s ecosystems was a key objective during the rebuild, and the site team ensured that ecological protections were incorporated into the project plan early on. In the end, ecological crews shifted over 16,000 seals, 5,000 fish and 150 lizards to protect them from earthquake damage and related works. Plus, 34 archaeological sites were discovered with more than 400 artefacts moved to a new whare taonga for protection.
