Inquiry #3: Bid item 58 Concrete Barrier 60MGC has 31,800LF. Can the state give a table detailing the height of the wall every 50' to allow for accurate estimating? Just giving the range of the variable for this item does not help because the length of the item is so large.

Inquiry #8: Bid Items 58 (60MGC), 61 (60MGCF), 65 (60MGC Mod.) and 92 (60MC Mod.) are all labeled as some sort of C barrier which will required Cross Sections that give elevations for both sides of the barrier. This information is required to correctly calculate the additional concrete, rebar and labor to install taller walls. Giving a range does not work. This information is critical not only for calculations but also productions. With this information missing the state must push the bid date in order to accurately bid these items.
