Evergreen Line Rapid Transit Project - Aberdeen Ave Storm Culvert & Roadworks

Contract Value

$800,000

Location

Aberdeen Avenue, between Bond Street & Lansdowne Drive, Coquitlam

Completion Date

April 30, 2016

Description

Storm Culvert work began with the demolition of an existing concrete headwall and box culvert. The inlet structure was replaced by a fibreglass headwall and 1350mm concrete pipe connected to a 3,050mm x 3,050mm box manhole 6m deep. The 1350mm pipe was then extended 100m from the manhole and tied into an existing CMP. Installation of the box manhole proved very difficult due to the extreme wet weather, the underlying wet and soft clay supporting the box manhole and the proximity to the guideway. The Roadwork portion included grading, paving, concrete curb and gutter and street lighting on Aberdeen Avenue. Work on Barnet Highway involved realignment of traffic island to effect the change in traffic pattern entering Aberdeen Avenue.
