| Abstract: |
Waiho – (verb) (-ngia,-tia)to let be, leave alone, put, place, ignore. SH6 Waiho Bailey Bridge is located just south of Franz Josef township in the South Island of New Zealand and is a critical connection for the West Coast. The Bailey bridge was first constructed in 1990 and has since been raised and extended three times due to significant aggradation of the riverbed. During a massive storm event on March 26, 2019 the northern abutment and northern- most pier were washed out leading to collapse of several spans of the bridge. The cost caused by the loss of the bridge was estimated to be in the order of $2-3M per day. Consequently, there was intense pressure on Waka Kotahi NZ Transport Agency to restore access across the river. As Team Leader and Deputy Team Leader of the West Coast Bridge Management Contract, Jeremy Waldin and Ben Baty led the $6.5M emergency recovery managing an emergency response team which worked across multiple organisations to recover this 170m long bridge in just 18 days. |
