This AC pavement comes under “Bid Item # 0006:

Deductive Item No.5: The Basis for this deductive Item No.5 is to delete road near ECP”. Please advise if this 18” Barrier curb falls under Bid Item # 0006 or Bid Item # 0008 or Base Bid Item # 0001.

ANSWER: See revised drawing CS401 in Amendment 0004.

82. In specification section 31 23 00.00 20 paragraph 3.15.2.4, please consider clarifying the requirements for compaction testing subgrade and fill materials every 250 SF to apply only to subgrades and structural fills below buildings/foundations. For the open site grading and compaction, such as below the gravel pavement, sidewalks, vegetated berms, & AC roads, recommend the requirement could be changed to something less stringent; possibly one test per 250 square yards? As an example, the >28,000 SF of Type A Gravel Pavement, would require ~112 density tests on the subgrade. Testing on a 16’ grid, seems excessive, for areas that will receive a fairly consistent compaction effort.
