Problem:

The new walkways around Arrowhead are part of the million dollar renovation taking place at the stadium. Several new beams were constructed to support these extended walkways. After the steel for the beams had been assembled concrete was poured into the forms prior to an inspector approving the construction. The inspector required an accurate, non-invasive method of confirming the reinforcing steel and stirrups were properly constructed.

Solution:

The on-site structural engineers contacted Construction Solutions to have someone "X-Ray" the beams in question. GPR equipment was brought on-site to evaluate the beams. Seen above is one of the beams in question. The rebar and stirrups were laid out with temporary marking and results were noted by the engineers and inspector. Upon completion of the GPR scans on all related beams it was confirmed that the beams were properly constructed, saving the contractor thousands of dollars from exposing the steel and repairing the beams.
