Site 14A:
~ The railroad flagman was on site despite the fact there was no ongoing work over the railroad. It was noted that this would have been a good job for A+B bidding for the railroad flagging pay item.
~ The Materials and Tests unit noted that the Type 3 bolts in the end bent diaphragm were weathering bolts, but the Standard Specifications require mechanically galvanized bolts for painted structural steel connections.
Site 14B:
~ It was noted that an improved design of the end bents would have shortened the bridge by several feet.
~ There were questions on the final location of the barrier rail in relation to the coping on top of the very long MSE walls.
~ The Geotechnical Engineering Unit is considering the use of alternative backfill material for MSE walls.
~ There were questions on the cost-benefits of large modular joints.
A/I ~ Structure Design will work with the Project Services Unit -- Contract Office to develop and try a couple of alternative flagging payment methods.
