This is a Physical Works contract for the demolition and replacement of SH26 Onetai Stream Bridge (BSN841). Onetai Stream Bridge is a 9m long bridge located approximately 14km north of Paeroa and carries SH26 over Onetai Stream.

The Contract Works comprise of:
• Replacement of the existing Onetai Stream Bridge with a bridge comprising a timber superstructure;
• Construction of new reinforced concrete abutment;
• Construction of new mechanically stabilised embankments with mass block retaining walls;
• Construction of instream scour protection measures including reno mattress and rip rap;
• Civil works including safety barriers, pavements, carriage widening, roadside furniture, signage and line marking;
• Temporary traffic management;
• Service relocations and protection
• Temporary Works design including but not limited to temporary propping, craneage and confirming adjacent ground conditions for crane foundations and improvements if needed.
• Riparian planting.

The Contract period is 60 Working Days and the Due Date for Completion of the Contract Works is no later than 30 June 2024. It is envisaged that the Contractor will utilise a single full road closure to undertake the majority of the site-based Contract works. This road closure has been included as a Separable Portion, with flexibility given to Contractors regarding the timing and duration of the Separable Portion.

The new timber superstructure is viewed by Waka Kotahi as a prototype solution for sustainable replacement of short-span vehicle bridges. The glue-laminated timber and plywood deck and kerb materials for the new superstructure are being supplied by Waka Kotahi.
