Deck Installation

Supreme Steel was engaged by the APJV to complete the installation of the new bridge deck at the Walterdale Bridge Replacement project. This project in Edmonton’s river valley, included a bridge realignment with 675 ft. span over the mighty North Saskatchewan River. The 5,500-ton bridge structure consists of deck steel hanging from a complex double arch. Supreme’s scope was to erect 25 bays and 240 meters of bridge deck simultaneously from each side of the river.

This project showcased the excellent supervision and construction experience of Supreme’s personnel. The scope was completed 2 weeks ahead of the contract schedule, despite losing two weeks to rain, wind and rising river levels. Supreme provided this significant time and cost saving to our client by utilizing existing large crawler cranes on site which negated the need to erect the steel from the deck. This allowed APJV access to install forms and to pour their concrete deck sooner. Supreme is very proud that our crews worked 18,000 man-hours on this project scope with no lost time!


Share Pathway Installation

The finished Walterdale Bridge Replacement Bridge, already an impressive structure, also includes a dreamy architectural pedestrian structure hanging on the downstream side arch. Based on the success achieved during the installation of the Walterdale Bridge deck, APJV awarded Supreme with the assembly and installation of the Shared Use Path (SUP), which runs parallel to the bridge.

Supreme’s scope included the assembly of 58 modules (previously fabricated in Korea) into 11 super modules at our Acheson location before transporting them to the Walterdale site and completing the installation. The project created a unique set of challenges for the project team. With the early involvement we see in most projects, we are able to work with designers to create a product that is fabricator and erector friendly; however, that was not the case with this project. As these components where delivered in completed sections, Supreme had to look at different ways to execute our scope, developing and execution strategy based on what was available to us and not necessarily what we would have preferred to see. While this was a challenge at the time, it was a great opportunity for the project team to think outside of our normal execution mentality and still provide our customer with the right end product at the right price.
