X SCR 575.04 (c) calls for the deck to be assessed for deterioration and all areas repaired. Would the government be willing to state a quantity of repair the contractor should allow for? Some of the bridge contractors are leery to bid on this project due to the fact that they could be held liable for a large amount of repair should deterioration be uncovered on these bridges being paid Lump Sum. The government could end up paying much more than needed if the contractor is to bear all risk associated with the soundness of the bridge deck.
No. Bid accordingly. 10/10/2017

Yes. Sheet J.1 requires 4” x 4” ‐ W6 x W6 welded wire mesh OR No. 4 bars for slab reinforcement. Use epoxy coated material for all steel used in the construction of concrete pavement. See Subsection 709.01.

X Section 601 in the special provisions states that a water attachment is to be used on a special exposed aggregate broom.
