LAFAYETTE — Structural deficiencies identified in late 2008 at the Cajundome have been completed ahead of schedule and under budget, said the arena’s operation manager.

Since late 2008, support beams had been used to provide extra reinforcement to weak points identified within the outer wall system of the building.

A permanent bracing system along 84 points in the outer corridor of the arena is now in place, said Phil Ashurst, Cajundome operations director.

Steel plates were bolted together to the inside and outside of the walls creating a sandwich system, he said.

“We’re good for another 50 or 75 years,” Ashurst said.

The reinforcement was needed because adequate steel reinforcement wasn’t used in the building’s initial construction nearly 30 years ago, he said.

Initially, the repair estimate was $1.2 million, but the lowest bid came in at $1.7 million for the scope of work.

The state’s Interim Emergency Board had approved the $1.2 million in funding with the university covering the additional cost, Ashurst said.

J.B. Mouton Inc. began the work in August 2010 with an expected 18-month completion date, but the contractors were able to complete the work this past March despite having to work around the arena’s scheduled events.

The final project was about $1.65 million and included additional repairs such as new sidewalks along the building’s exterior, Ashurst said.
