Additional parts of Allen’s Eagle Stadium will need to be fixed before it can reopen, according to a new report released Thursday.
The report, done by engineering firm Nelson Forensics, found seven "structurally deficient" areas at Eagle Stadium: retaining walls, concourse framing, press box support columns, press box structure, single-story structures, main scoreboard and durability of the structure.
“These are primarily engineering failures,” said Ryan T. Chancey of Nelson Forensics, in a statement. “While the concourse is the largest and most serious area, we did find failures in the structural design throughout the stadium.”
Allen ISD said the problem areas do not meet building codes at the present time.
Structural problems include inadequate concrete columns that support the press box, insufficient steel framing of the press box, connections at the base of the main scoreboard that are not strong enough and a retaining wall that does not have adequate steel reinforcement. Allen ISD said the school board wants repairs to begin later this summer so the stadium can reopen in-time for graduation in May 2015.
Engineers found no issues in the concrete seating, the concrete pier foundations that support the above-ground structure and a smaller scoreboard.
The stadium was designed by PBK Architects and built by Pogue Construction. Both have agreed to pay for the repairs, but it’s unknown how much each company will pay.
“They have both committed publicly, verbally and in writing that the repairs to Eagle Stadium will not cost the community of Allen and that we will get the stadium that we initially asked for,” said Allen ISD Superintendent Dr. Lance Hindt. The stadium gained national recognition when it opened in 2012 - some good and some bad - for the amount of money spent by the district, $60 million, and its large seating capacity, 18,000.
Eagle Stadium has been closed since February when cracking in concrete throughout the concourse was deemed unsafe.
Now the focus is on whether or not parts stadium have to be torn down, or if the cracks can be sealed.
Chao says the smaller cracks can be filled while the columns might need reinforcement.
“There's a way you don't have to take that down,” said Chao. “It would make the cost too much; you could just make the columns stronger.”
But if the cracks let air and water corrode the ribar, the repairs may be more extensive and expensive.
In May, the district announced the stadium would be closed throughout the 2014 football season. Allen will play home games in neighboring stadiums in Plano.
