This project involved the strengthening of the concrete arched ribs on two hangars. Steel arch plates were bolted and epoxy bedded to the top and underside of the concrete arches using Ultraplus bolts. Because of the high ceiling, the contract was a major exercise in scaffolding. To strengthen the ribs, Dominion Constructors built a large mobile scaffold the full height of the hangar, which was winched progressively from the front to the rear.
