Inquiry #1: Bid Item #9 for Prepaving Grinding is listed as a Lump Sum. Historically, this item has been quantified by days to avoid disputes tied to the new MRI/IRI specifications. By not quantifying this item with a suitable unit of measure, the design of the project now rests solely on the contractor as they may choose alternative methods of construction (Mill & Fill vs. ALR Grinding vs. HMA Leveling). This will ultimately lead to an imbalanced playing field as the contractors now partake into an integral part of design during the project bidding / building phase. For an example, if a contractor decides to mill the entire project limits to achieve the desired pre-pave MRI/IRI specifications, than the new .10’ layer of RHMA may not be sufficient as the overall structural section has been significantly reduced. Lump Sum bids received will not be true comparisons of each other nor reflect similar scope. This concern is currently being discussed in the STG meetings with Cal Trans Headquarters and has been determined that there are significant issues in changing the unit of measure from “Days” to “Lump Sum”.
Please change Bid Item 9 quantity from “Lump Sum” to “Days” and quantify the amount of days necessary so ALL contractors can accurately bid the project and ALL prices are reflective of the same scope.
[Feel free to reference contract 11-2M9604 (bid 2/16/17) and 10-1F5704 (bids 3/15/17) which had similar issues during the bidding phase pertaining to Prepaving Grinding. Ultimately, an addendum was issued on both of these contracts changing the unit of measure from Lump Sum to Days.]

Inquiry #3: On sheet Q-1, Summary of Quantities, Charts Repair failed areas and Shoulder repair failed areas have an overstated amount of Cold plane (bid item 16) as well as HMA (bid item 10). Specifically the first description in both charts EB Rte 152 On/Off-Ramp which has a length that is twice the amount shown on sheet C-2 for this location. However, the widths shown in the same charts appear to be correct. Will the state please verify their quantities for Bid item 16 and 10

Response #2:Quantities for Bid items 10 and 16 are correct. Length shown on Q-1, under "Repair Failed Areas" EB Rte. 152 ON/OFF Ramp is correct for ON-RAMP length and OFF-RAMP lengths together. As shown on sheet C-2:
EB Rte. 152 ON-RAMP = 1050 L.F.
EB Rte. 152 OFF-RAMP = 1050 L.F.
for a total of 2,100 L.F. (which is shown on Q-1)
For further clarification, please see Motorist Information Plan sheet MI-1 and MI-2.

Inquiry #4: On sheet Q1, Summary of quantities, Chart, Conform taper at Public road intersections has values that do not equate. All Area calculations are in error, as the width and length when multiplied do not equal the corresponding SY. Will the State please verify that their quantities are correct for bid item #10 (HMA)?

Response #2:Summary of Quantities, Chart, Conform taper at Public road intersections bid item #10 (HMA) quantities are correct.
Details shown on sheet C-1 identify values reflected on sheet Q-1 correctly, but additional quantities
are needed for the tapered portion of the public intersections. In order to account for flared/tapered sections of the public intersections and calculate total square yards, additional quantities were added.

Inquiry #5: In response to the State's response on inquiry #3. If the length is correct as Caltrans states in their response AT 1050 LF for each ramp, than the width is in error as neither ramp has a traveled way of 28' wide as currently shown. Sheet Q-1, Summary of Quantities, charts repair failed areas shows a width of 28' wide for 2100 LF. Obviously the width is 14', and can be easily field measured or viewed on Google earth. Basically EB Rte 152 ON-RAMP= 1050 LF Long and 14LF wide and EB Rte 152 Off RAMP =1050 LF long and 14 LF wide. When you multiply them you get a value of 3,267 SY not 6,534 SY as shown on Sheet Q-1. The same error exists in the Shoulder repair failed areas. Will the state please revise the quantity for the Cold plane and the HMA quantities?
