The Tatin Creek crossing consisted of a multiplate pipe arch carrying Tatin Creek under Highway 16, approximately 1 kilometre east of Endako, BC. The pipe arch had failed and was causing continuous deterioration of the highway at this crossing.
Allnorth was engaged by the Ministry of Transportation and Infrastructure to provide conceptual designs and a detailed design for a new bridge and road approaches.
The crossing was designed as an 18.65 metre long, pre-cast/pre-stressed box girder bridge on pre-cast concrete pile caps, supported by steel pipe piles. Allnorth’s scope of work also included preparation of tender documents, an engineering construction cost estimate, potential construction procedures, a traffic management plan, an environmental management plan, a culvert deactivation plan and environmental permitting.
