The Georgia Mountains Center parking deck under construction in downtown Gainesville is being precast according to schedule, and builders say they aren’t fazed by this week’s deck collapse in Atlanta.

"The biggest step in construction to avoid something like that is inspection," said project manager Jarrett Nash. "We’re using all due diligence to have qualified contractors and inspect them to make sure they’re following through with job requirements."

On Monday, part of a six-floor parking deck near the Georgia Tech campus fell, crushing 35 cars. A horizontal beam designed to hold up a floor section of the deck collapsed, but structural engineers haven’t determined why it happened, David Tyndall of Gateway Development told WSB-TV.

J.P. Spillane, Atlanta police assistant commander of the zone where the deck is located, told the Associated Press there were signs of bolts popping on the other side and he was worried about "the entire soundness of the structure."

The accident was "probably a failure in connection or some type of overload," said David Bass of Bass Precast Erecting, the Cleveland company that is building the downtown Gainesville parking deck.

"I can assure you that our precast is engineered correctly," he said Thursday. "I was at the site this morning, and our job is right on its five-week schedule."

University of Georgia officials have asked for inspections of two parking decks under construction by the same contractor as the garage that collapsed in Atlanta.

A 488-space deck at UGA intramural fields and a 445-space deck near the Performing and Visual Arts Center on East Campus are slated for completion by fall. Atlanta-based Hardin Construction Co. is overseeing the projects and volunteered to have an independent engineer chosen by UGA to inspect the decks under construction.

Precasting concrete has "been around for a long time," Bass said. "The reason owners choose that over pour-in-place is because it’s faster, cleaner and comes in multiple colors. Instead of taking six months, we can erect it in five weeks."

The four-level deck, expected to be complete in September, will hold 419 vehicles when complete, and is designed to allow growth to a six-level deck.
