Demolition of the existing site was completed last summer, an extraordinarily complex process that was implemented without error or an injury. The site has been a hub of activity ever since, and the indispensable crane has been central to the ongoing progress of Ottawa’s largest development project in years.

“This is the time that we move in the steel and place it structurally so that the OCC shell is formed,” said Valerie Roux, Engineering Manager at the OCC. “We have been fortunate that the weather has cooperated with us, but regardless of the weather, we will not slow down. The iron and steel workers have been outstanding in their efforts and performance.”

For the OCC, steel or rebar is the priority right now. Rebar, or reinforcing bar, is a common steel bar, commonly used in reinforced concrete and reinforced masonry structures. It is usually formed from carbon steel, and is given ridges for better mechanical anchoring into the concrete.

“The iron workers on site at the OCC have a critical role to play,” said Gaeten Sigouin, business manager of the International Association of Bridge, Structural, and Ornamental & Reinforcing Iron Workers Local 765. “The installation of metal structures forms the skeleton, and as well provides the structural and architectural concrete components for the new OCC. It is great to see the facility begin to take shape.”

The iron and steel workers have been working closely with the ‘form’ workers, the individuals responsible for pouring the concrete and ensuring the form fits the design.

“The concrete was just poured on Level 3, where the multi-purpose room is situated,” said Del Boudreau, of Carpenters Local 93. “We are next going to do level four which represents the upper height of the facility so we are progressing well. Ottawa is in an earthquake zone which makes the installation of steel structures particularly important.”
