FDH Velocitel has received a five-year, $10 million contract from the U.S. Army Corps of Engineers to provide architectural and engineering services to complete testing of tension in tainter gate trunnion girder anchor rods.
Tainter gate anchorage systems, which contain post-tensioned anchor rods, have been used in major U.S. dams since the 1960s, according to FDH Velocitel. In addition, the company says the number of rod failures has grown recently. About 150 dams across the U.S. used the post-tensioned anchor rods, with more than 50,000 post-tensioned anchor rods in Corps inventory, according to an FDH Velocitel press release.
FDH Velocitel will use its proprietary nondestructive testing method to enable the Corps to safely and effectively manage its aging inventory of post-tensioned anchor rods. Development of this technology was made possible through legislation supported by Congressman David Price, FDH Velocitel says, which helped form the government-industry partnership that enabled the deployment of this test method on Corps dams.
“For the past four years, we have worked in partnership with the USACE Engineer Research and Development Center (ERDC) in Vicksburg, MS, to develop and deploy this service — which reduces testing costs by up to 90%, while significantly improving safety,” said Robert Lindyberg, PhD, PE, vice president of technology/R&D for FDH Velocitel.
FDH Velocitel is an infrastructure assessment, engineering and construction services company that supports the telecommunications, heavy civil and power transmission markets.
