Inquiry #1: There are no drainage plans or profiles for drainage systems 1, 2, 3, 4, 5, or 8 included in the plan sheets for this project. Can you please provide?
Inquiry submitted 08/05/2019

Response #1:Submitted for consideration.
Response posted 08/05/2019


Response #2:There are no drainage plans or profiles for drainage systems 1, 2, 3, 4, 5, or 8 included in the plan sheets. Refer to Note on plan sheet DQ-1. These locations are Cure In Place Pipeliner (CIPP).
Response posted 08/05/2019




Inquiry #2: It is understood that these locations are cured in place pipeliner installations, however, a pipeliner installer need the information that the profile sheets supply. Also, a pipeliner installer doesn't even know where the locations are where the liners are to be installed. Makes it difficult to supply a realistic bid number.

Inquiry #3: Supplemental information included several cross sections for the project however, there are no cross sections for the mainline other than the areas crossing under Mountain View Ave and Bethel Ave. Can the State provide cross sections for the entire Mainline?
Inquiry submitted 08/14/2019

Response #1:Submitted for consideration.
Response posted 08/14/2019


Response #2:There are no cross sections for the mainline other than the areas crossing under Mountain View Ave and Bethel Ave. because there is no profile change at these locations.

Inquiry #4: JPCP quantities
Sheet 222 of 318, Summary of quantities, shows 157.7 CY of concrete for the JPCP work from station 825+80.02 to 837+15.80 NB and 158.4 CY of concrete for JPCP work from station 825+90.53 to 837+31.
The quantities appear to be insufficient to perform the work detailed in the plans for JPCP between the indicated stations.
Would you please review the quantities and indicate if they are correct or if the quantities and or required work will be changed.

Inquiry #5: Ramp Transition Paving.
Sheet 222 of 318, Summary of quantities, Ramp Transition Paving table provides quantities of concrete for the ramp transitions. It appears the amount of concrete provided is intended to cover placing both the ramp transition and the adjacent mainline shoulder. Is the mainline shoulder to be consider part of the Ramp Transition and reinforced per Table S, on standard plan P35.
If the shoulder is part of the ramp transition paving, what is the location of the Isolation Joint. I.E., between the JPCP ramp and the JPCP shoulder or between the JPCP shoulder and the CRCP lane.
Additionally, would the longitudinal joint that is not the isolation Joint be tied?

Inquiry submitted 08/28/2019

Response #1:Submitted for consideration.
Response posted 08/28/2019


Response #2:The mainline shoulder is not part of ramp transition paving. See Typical Cross Section X-2.

Inquiry #8: On Sheet X-4 and sheet 228, Mountain View Ave cross section is shown depicting the new retaining walls, MBGR and existing roadway section. The existing guard rail will need to be removed prior to excavating for the proposed retaining wall, as the excavation will directly impact the structural integrity of the MBGR Posts. We will need additional K-Rail quantity to both protect the travelling public as well as our crews. Will the State please add additional K-Rail quantities for this work? Furthermore will the State please add additional Dike and AC quantity, as the excavation will more than likely destroy existing Dike and a portion of the AC shoulder? Section 12-4.02C(3) of the specifications does not address allowing flagging or lane closures on Mountain View Avenue. Will the State please provide a lane closure chart for the work involved at these locations?

Inquiry #11: Will the State please consider increasing the allowable number of working days for this project? Currently the maximum number of working days is set at 255 WD. This extremely tight timeline does not appear to be achievable with 6 phases each at just over 42 Working days apiece. Please consider revising the allowable number of working days on this project.

Inquiry #12: The cross sections, quantity tables and layout for the ramp areas are ambiguous.
For example
From mainline station 837+31.09 to 875+40.00 the typical cross section on sheet X-2 shows that the CRCP is 26 feet wide and on layout sheet L-2 from station 837+15.80 to 848+73.70 shows that JPCP paved shoulder is 10ft wide. It appears that there is a 2-foot overlap of the JPCP and the CRCP. Additionally, it appears that the quantity of the concrete in this 2-foot overlap is included in both the CRCP and JPCP quantity summaries.
Please clarify what cross section is to be constructed at each of ramp locations and make any need corrections to the quantities of JPCP and CRCP needed.

Inquiry submitted 09/06/2019

Response #1:Submitted for consideration.
Response posted 09/08/2019


Response #2:Written stations shown on Plan sheet X-2 include the widths of the CRCP. No corrections on the quantities are needed.
Response posted 09/10/2019




Inquiry #13: In the response to Inquiry #12, you addressed the widths of the CRCP in the ramp transition areas and the quantities of CRCP, but you failed to address the JPCP. As you have not provided details for the JPCP paving outside of the ramp transition paving, i.e., the JPCP on the mainline shoulders, one is left to scale dimensions from the provided layout sheets that show the areas of JPCP. Scaling the JPCP areas indicates that the JPCP overlaps the CRCP. Further, on Layout sheet L-2 at station 848+73.70 for ramp R-1, the dimensions given for the JPCP is 10 feet. With what you have provided in your response to Inquiry #12, the width of the JPCP at this location would need to be 8ft rather than the 10ft that is called out on the layout sheet. This same callout of 10ft is repeated at R-2, R-5, R-6, R-7, R-8, R-9 and R-10. If the JPCP paving between the Ramp Transition Paving and the CRCP is something other than the 10ft shown then you need to correct your quantities of the JPCP as originally requested in Inquiry #12.

Response #2:Mainline stations 837+31.09 to 875+40.00; the typical cross section for CRCP is 26 feet wide as shown on sheet X-2. Exception will be at the JPCP "RAMP TRANSITION PAVING" where the CRCP is 24 feet wide.

Attention is directed to: Typical Cross Sections Sheet X-2, "Ramp Transition Paving"(cross section); Layout Sheet L-1, "Legend" - "Ramp Transition Paving JPCP Shld"; and the respective Layout Sheets with cross hatching represented by the hatching described in the "Legend".
