National Jamboree Construction Update | CONSOL Energy Bridge | Summit Bechtel Reserve

Need jamboree info? Go to http://bsajamboree.org Good weather and strong teamwork has resulted in lots of construction progress on the CONSOL Energy wingtip bridge. We've got rebar and concrete in the abutments as well as substantial progress on the pier and masts. This stuff isn't easy. As the concrete gets poured here at the Summit, we have to make sure that it's meeting the strength requirements of the design. The testing process is pretty cool. Each truck gets tested. So, our engineers grab a few cylinders of concrete from every batch, and cure them individually. Then (the fun part) we get to break each one as they've cured for different periods of time. If they don't pass the cure test, we go back for a new batch of concrete. We're also drilling holes for the anchors. The concrete has to all the way down into the hole; 133 feet! All this work is adding up to one really impressive bridge. The Wingtip Bridge will be a showpiece in the 2013 National Jamboree, and at the Summit for generations to come.
