Project scope

On June 19th 2018 Coldstream Concrete Ltd. supplied a ten-piece open-bottom precast concrete culvert to Wayne Schwartz Construction Ltd. (Miller Group) in Grey County, Ontario. The culvert spans 5.5m and sits 2.5m tall. In typical precast fashion it was installed in less than one day, resulting in shorter road closure times for the public. The second phase is set to be installed in mid August which includes a second precast culvert with similar properties of 10 + 590.

Fleming Road

Plympton-Wyoming, Ontario

Project scope

On July 11th Coldstream Concrete Ltd. supplied a 12-piece “all skewed box culvert” for the town of Plympton-Wyoming. Each piece of he 3.6m span by 2.1m rise box culvert was constructed on a 30-degree skew. This was done in order to avoid large/heavy end units which are typical for precast skewed end culverts. Due to the fact that all pieces were designed to the same physical dimension (without large heavy end units), all 12 pieces were installed quickly and safely by 2pm the day they were delivered.

Chinnick Drain and Pump Station

Chinnick Drain and Pump Station

Mun. Chatham-Kent

Project scope

In June 2015 Coldstream Concrete supplied 2 large pump stations that were 7.2m x 3.8m x 6.2m deep to the Chinnick Drain and Pump project in the Municipality of Chatham Kent. These chambers house pump intakes and collect water from the Chinnick Drain which is then pumped into Lake St. Clair. The entire one end was open to receive water from the drain. Due to the high water levels buoyancy issues had to be considered. The 3 walled chamber caused structural problems. This was remedied by inserting 25m rebar into preformed vertical tubes that extended through all the riser sections, base and cap. This created horizontal and vertical reinforcing grid and joined all the elements together. Each chamber consisted of 9 units. All 18 united were installed in the winter with water issue over 1.5 days.

Bridge 417 – Thompson Line

Central Elgin County

On October 15, 2015 Coldstream Concrete supplied an open bottom precast culvert that had a 11.5m span and 3.5m rise to the County of Central Elgin. Relatively dry conditions were very helpful during the installation due to the size of the watercourse and excavation. The culvert consisted of 15 units to create a 16m wide roadway. This single structure replaced a design for a dual box culvert. This is turn reduced the total project cost and created better watercourse flow. Coldstream also supplied precast concrete footings. The total installation time for footing and bridge elements was under 2 day.
