INDIANAPOLIS -- Heavy thunderstorms that hit Indianapolis late Tuesday caused some flooding at Lucas Oil Stadium, the new home of the Indianapolis Colts scheduled to open next month.

The Indiana Stadium and Convention Building Authority on Wednesday discussed the extent of the damage, 6News' Norman Cox reported.

Officials said the roof did not leak, but three of 20 drains designed to gather and direct water away from the stadium were damaged. By Wednesday afternoon, officials said all three had been fixed.

On the southwest corner of the stadium, lower rooms that include electrical and phone equipment had water damage.

Floors were saturated in meeting rooms on the northeast corner of the stadium. Water also got into a data room that stores wireless equipment.

Some of the underground loading docks were also damaged, stadium officials said.

There was no damage to the playing field, suites or regular seating area.

It was not immediately known if the strength of the storm, a construction issue or design flaw caused the damage.

A worker who wanted to remain anonymous told 6News Wednesday morning that as much as 4 feet of water was standing in some places.

The cost to repair the damage was not immediately known. Stadium officials said the August opening of the stadium is not expected to be delayed.

Contractors began working to shore up the damaged areas shortly after the storm ended.

"Crews responded immediately to manage, assess and begin the process of damage repair and restoration and will continue working to ensure the project is completed on time," said John Klipsch, executive director of the ISCBA.

The $700 million stadium will host the Super Bowl in 2012.
