Installation of the 220-ton bridge girder for the North Bay Pedestrian Bridge, Toronto, ON. M A R C H 2 0 2 4 | 49 Structural Steel P H OTO G R A P H Y CO U RT E S Y WA LT ER S G RO U P As a fourth-generation family business, Walters Group is responsible for many iconic Canadian structures, including Calgary's The Bow featuring full height atrium spaces and exposed structural framing for all 58 floors. Two of its more recent projects also approach iconic status and are prime examples of tricky engineering logistics accom- plished with maximum efficiency. In December, Walters Group along with EllisDon installed the long-awaited North Bay Pedestrian Bridge that connects CIBC Square to Union Station in Toronto. The 220-ton bridge girder was shipped in a single piece by barge from Hamilton, and an engineered ramp was constructed to offload and transport the girder to the site. Pinnacle Logistics, along with Western Mechanical Electrical Millwright Services Ltd. (a heavy transport com- pany) were credited for managing the logistics that enabled Walters Group and its partners for taking only six days to complete the entire installation. Meanwhile, Walters Group and Suffolk Construction held a topping off ceremony in Boston for the new 10 World Trade building, a 555,000-square- foot structure with flexible floor plates and designed with swooping geometric forms (the building was also designed to address the effect of a predicted 40-inch rise in harbour water levels by 2070). Last but hardly least, family-owned Corbec, which has been providing solutions in the structural steel realm since 1965, has of late focused increasing attention on the benefits of galvanizing – in which Corbec is a leader thanks to four galvanizing facili- ties and generations of expertise. Corbec cites the Cariboo Falls project as an exam- ple of galvanizing being specified for its coating durability, corrosion performance, sustainability, plus initial and life-cycle costs. The four generating stations and other infra- structure clustered around Cariboo Falls in Northern Ontario were hot-dipped galvanized 60 years ago and remained maintenance free, so when it came time to undertake the first major upgrade, Ontario Power Generation again specified galvaniz- ing for all the exposed steel, including structural, fasteners, railings, and walkways. Corbec's experience with extra-durable HDG coating was vital for this project, and the high capacity of the HDG steel ensured rapid reliable turnaround of the two-and-a-half million pounds of steel needed during the short northern construction season. Also, Corbec's on-floor information systems ensured the proper identification and delivery of every piece of steel to each work site location, facili- tating seamless assembly and erection across the remote project complex.
