Highway 29 Relocation – Design and Survey
Binnie was the Prime Consultant and Project Manager responsible for coordination of the Highway 29 relocation assignment in northeast BC. Binnie’s Project Manager oversaw this complex and multi-disciplined project, which included Environmental, Geotechnical, Structural, Geometric, Survey, Hydrological, Road Safety Audit, Multiple Accounts Evaluation, and Socio-Economic consultant team members. The project is 20 km in length with four major bridge crossings.
As part of their scope of work, Binnie Engineers prepared the Definition (Preliminary) Design of the new bridge structures and associated roadway infrastructure along the segments of Highway 29 that will be relocated. Geotechnical challenges included instability associated with poor fine grained silt and clay, sourcing of suitable riprap, landslide induced reservoir waves, and bank erosion.
Binnie survey crews established control for 60 km along Highway 29 using static GPS and levelling. They also provided topographic survey of a segment of the road.
