NOTE
If a hole is observed, monitor the
bridge or rafts performance. If
visual evidence of taking on water
is observed (such as riding low in
water), pump the water out while
operations continue. If the water
intake is faster than the pumping
capacity, remove and replace the
damaged bay. The damaged bay is
deadlined until repairs are made.
