PRECAST CONCRETE
PRODUCTS

Downtown underground power projects continually face challenges with space and time, making turnkey solutions a welcome consideration. The Knelsen Precast Modular vault design is used under city sidewalks to house large transformers needed to power surrounding buildings. This design allows for flexibility in length, grade level, and surface finish while also clearing bridge decks, elevated guideways, and tight city streets during transport to the site. The end results are accelerated installation, reduced surface disturbance, and flexibility in surface finish.

Knelsen Precast offers a simple, fast, and effective solution to the installation of concrete-encased duct banks with the use of precast duct banks. These are generally cast in 3-meter lengths for easy handling and offered in multiple configurations—using 4, 5, 6, or 8-inch pipes. This precast solution will minimize onsite workers and traffic closures while enabling same-day excavation and backfill versus onsite rebar assembly, casting, and curing. Additionally, precast quality and in-house testing provide improved product performance and fitment on-site while also contributing to improved safety by reducing open excavation and the number of workers in the trench.

Knelsen has contributed to several key underground electrical utility projects throughout Western Canada. Most recently, our Precast Division worked on the new 30-acre, 304,000 sq. ft. plant owned and operated by SOFINA Foods in Calgary. This project required four large electrical vaults on-site, as well additional offsite vaults, to deliver power to the new plant. All vaults meet Canadian Traffic loads of CL-625, featuring 6-inch knockouts all around and providing maximum flexibility for current and future needs.

The City of Calgary LRT bridge design called for the use of precast concrete deck panels in tandem with cast-in-place elements for accelerated construction and long-term durability. These panels were constructed off-site under controlled conditions within our precast plant and brought to the bridge site ready to be installed and connected. The benefits of using these precast full-depth bridge deck panels include high-quality durable materials, minimal on-site construction, and increased safety for construction crews.
