Project Description

Robinson Consultants Inc. was retained by the City of Ottawa to complete the preliminary and detail design of the extension of Brian Coburn Boulevard from Mer Bleue Road to Navan Road, and the widening of Mer Bleue Road, from the previous widening limits at the Hydro One corridor (south of Innes Road) to north of Renaud Road. The Mer Bleue Road portion included design and construction of a 1km section of the existing Mer Bleue Road corridor from a two-lane rural cross-section to a four-lane urban arterial cross-section, complete with pedestrian facilities and dedicated cycle lanes. The Brian Coburn Boulevard portion included the design of the ultimate four-lane cross-section and the design and construction of the interim two-lane cross-section for the new 3.2km Brian Coburn Boulevard corridor, including on-road and off-road cycling facilities. Both roadways included stormwater management (SWM) analysis and drainage design, and construction of roundabouts at all intersections.

The design for the project was extended to include development of a Species at Risk compensation plan and the development of a temporary Park and Ride facility concept adjacent to the project site, adjustments to the Mer Bleue Road construction limits, and the requirement for the design of the future outlet sewer. Other additional scope included temporary utility relocations, and post tender design modifications to address updated AODA requirements, streetlighting changes identified by the City, asbestos removal and dewatering required for one property demolition identified after the project had been tendered and temporary intersection repairs required at the intersection of Mer Bleue Road and Brian Coburn Boulevard.
