PEARSALL, Texas -

A design flaw at Ted Flores Elementary School caused major problems with mold in the second-grade wing of the school.

"The roof stopped here and the wall was here (with a gap between them). The membrane over time eroded and leaked and then it went down the walls and into the ceiling and over time the moisture got in and cause the mold issue," said Robert Lindemann, chief financial officer of the Pearsall Independent School District.

At first, Pearsall ISD officials thought they could clean up individual classrooms on a case-by-case basis, but then decided to demolish the entire second-grade wing of the school.

"That would have been just piece-mealing it and really wouldn't have solved the problem. We probably would have still had the mold issue in other parts of the building. This way, we're going to clean the whole second-grade wing up," Lindemann said.

The closing date to submit bid for the demolition is Thursday, March 28.

The bids will then be submitted to the school board on April 9.

Soon after that, it is hoped the rebuilding process can begin, and the students and their parents can begin to breathe easier knowing there is no longer a health hazard at the school.

"The safety and the education of their children are our No. 1 priority," Lindemann said.

The entire project is projected to be completed in October 2013.
