Buller District Council (BDC) (Principal) are seeking tenders for the protective coating refurbishments of two bridges in the Karamea area. These bridges are the Oparara river bridge and Mosseyburn Bridge located on SH67 Karamea Highway, Kohaihai Road, 5.6 km and 17km North of the Karamea township. These bridges are located in C5 & C4 Corrosivity zones on the West Coast. BDC is seeking tender submissions and prices for two specified protective coating options.
