SAN ANTONIO -- About six weeks after a light pole near a central Texas high school stadium crashed while spectators were watching a nearby soccer match, a San Antonio contractor is warning local school districts to check for faulty light poles after finding similar damage in other districts.

Bartlett Cocke General Contractors repaired the light pole hours after it fell in early March at Hays High School in Buda, Texas, and said it had seen other structural integrity problems in poles that had fallen across the region. The downed pole in Buda was manufactured by the Whitco Company out of Ft. Worth, Texas, said Kirk Kistner, Bartlett Cocke's vice president of marketing.

At least one school district in the Alamo City -- the Northside Independent School District -- had poles from the Whitco Company at one of its facilities. NISD Superintendent John Folks ordered the poles at Gustafson Stadium on the city's northwest side taken down after the Buda incident, said NISD spokesman Pascual Gonzalez.

"It was pretty shocking because these light poles are massive," he said. "They could cause a lot of damage (and) they could also hurt a lot of people had they fallen."

The poles, now laying on the ground, cost about $300,000, Gonzalez said, an amount the district would attempt to recover from the now-closed Whitco Company. Gustafson Stadium was the only facility in Northside ISD to use poles from Whitco, Gonzalez said.

Tests on the Gustafson Stadium poles found one with a hairline crack, Gonzalez said.

Kistner said they didn't know the specific cause of the problem with the poles -- either a problem with the steel itself or the manufacturing -- but that his company's engineers were working on figuring out the flaws and urged all school districts to test the integrity of its light poles.
