Supporting structure

The forms for the columns are made of curved steel sections bolted together. Here, the far sides of the columns are in place but the near sides are still open while the steel workers install the rebars. Later, the columns will be completed by bolting on the remaining steel forms, and then filled with cement. When cured, the forms will be removed, revealling the finished concrete column.

Scaffolding has been erected around both columns, and temporary steel beams cross the street. A working platform is being built on top of the steel beams.

  1. Neat! I'm out of town for awhile, and it's fun to be able to follow Ottawa projects through your blogs! Thanks.

  2. This is great Eric! We no longer need to visualize what an impact this arch is going to have in the neighbourhood. What a HUGE new landmark for Ottawa.
