Avia NG Airport Consultants reached out to Forterra Canada in December 2017 for assistance to design and build an infiltration tank. The Ottawa International Airport was expanding its apron area and needed to infiltrate water runoff back into the site as opposed to discharging it. Several design criteria needed to be met: 1) Structurally must […]
In 2017, LDS Consultants Inc. of London, Ontario completed the design of the Fanshawe Park Road project. In the spring of 2019, this project was awarded to CH Excavating (2013). One of the challenging aspects of this project was the requirement to install a large 3.0m diameter maintenance hole in one of the busiest commuter […]
The City of North Bay designed and tendered the project for the High Street Culvert. The design, fabrication, and delivery was awarded to M CON Pipe and Products Ltd. (Ayr, Ontario). The install of the culvert was awarded to Ed Séguin and Sons Trucking and Paving Ltd. The City of North Bay’s Engineering team sized […]
During the design process, selecting the appropriate material is always challenging, especially when multiple constraints are attached to the project. Professional engineers constantly deal with various issues that require in-depth knowledge of the engineering field related to the project. Management skills become more important nowadays as the project goes through the following five phases: Initiating […]
The existing storm water drainage system in the northwest sector of the city of Medicine Hat, Alberta was over capacity and could not meet the demands of the continual commercial and industrial growth in the area. The City of Medicine Hat imposed development restrictions in the sector until a solution could be found to relieve […]
Precast concrete box culverts and other drainage structures are being supplied to the City of Calgary’s Bonnybrook Wastewater Treatment Plant (WWTP) by Inland Pipe as part of the plant’s expansion project. The expansion will involve multiple construction phases over 10 years and will cost taxpayers a total of $800 million. Bonnybrook WWTP currently services the […]
IntroductionPrecast concrete has been widely used in constructing infrastructure for decades. Its ability to accelerate the construction schedule and improve the quality of the concrete are considerably superior to castin-place applications. The use of precast though, is limited by the product transportation, lifting and handling capacities. The Eglington Crosstown LRT Mount Dennis Station was a […]
Sewer pipes not only function as a conduit to transport stormwater or wastewater, but they must also have the load-carrying capacity for whatever is built above them. One fundamental difference between a rigid pipe, like concrete, versus a flexible pipe, like plastic pipe or corrugated steel, is that a concrete pipe can be reinforced to […]
What is self-compacting bedding?Self-compacting bedding (SCB) materials, also known as self compacting soil, self-consolidating soil, or high-performing bedding in some areas, provides self-flowing, self-compacting abilities under gravity, has free draining characteristics, and restricts the penetration of fines. It is a cohesionless soil consisting of uniformly graded clean gravel or crushed stone usually with a grain […]
Many underground infrastructure capital improvement projects are driven by capacity issues. The South Surrey Interceptorproject is no different. Work is wrapping up on Phase 2 of the Johnston Road Section of the project and, what many believe to be, the largest diameter microtunnelling project in North America. The project owner, the Metro Vancouver Regional District […]
