Inquiry #1: Bid Item 7 Roadway Excavation, quantity 1,550 CY. I have reviewed the typical cross sections, construction details, and the quantity sheets. Other than location as listed in quantity sheets, I have been unable to determine exactly where, and what type of, excavation is being performed at those locations. I was unable to locate any reference to roadway excavation on either the typical cross sections or construction details. Please clarify.

Inquiry #2: 80 Working Days are not sufficient to complete the work at different 38 locations mill, chip seal, pave, stripe with all other minor hma work items and the electrical works based on the traffic closure charts and daily allowed shift hours. We recommend to revise/increase the allowed working days based on the nature of the work.

Inquiry #3: Section 12-4.02C(1) indicates the traveled way must be open, however closure charts do not address shoulder closures. Please confirm continuous shoulder closures will be allowed full duration of ramp work.

Response #2:No continuous shoulder closures are not allowed. Shoulders are allowed to be closed only for the duration of time shown in their respective ramp closure, connector closure, and lane closure charts.

Inquiry #4: Bid item 12 REPLACE ASPHALT CONCRETE SURFACING requires a total of approx 100 tons of HMA Type A, to be placed method compaction, in multiple locations. Please clarify if the standard QC items and costs will be required, e.g. Startup evaluation, field and lab testing, for this very small quantity of HMA placed in multiple shifts.

Response #2:Please refer to sections 39-3.02 Replace Asphalt Concrete Surfacing and 39-2.02 Type A Hot Mix Asphalt and bid per the current contract documents.

Inquiry #5: Per section 37-2.05A General: Traffic must not be allowed on a SAMI. This coupled with the limited night time work hours, will cause a lot of these ramp locations to be performed over multiple shifts. The State needs to rethink their design strategy in order to provide adequate access to the project. As the project is currently designed there is no way to complete the work in the amount of working days given. The state is trying to accomplish too much work in to small of work window with to few working days.

Inquiry #6: Section 39-2.01A(4)(i)(iii) Pavement Smoothness - Requires the MRI to be no greater than 75 in/mi for a 0.1-mile section. The preconstruction inertial profile data provided in the bid indicates that more than 36 percent of the existing roadway has an MRI greater than 150 in/mi. The average MRI of the sections exceeding an MRI of 120 is 190. The range of the MRI values exceeding 120 is 185 – 310.

If the placing the overlay allows for one opportunity to improve smoothness (provided that the roadway does not actually get rougher due to spalling or delamination) it is unrealistic for the State to expect the smoothness to be improved to an MRI of 75 in/mi. when areas of the existing pavement have MRI values greater than 120 without extensive corrections either to the existing surface prior to the cold planing or to the final HMA surface itself.

Based on the aforementioned existing pavement profile data, it is apparent that extensive depth corrections will be required to meet the final smoothness requirements. The State will have to allow corrections prior to the cold planing and/or via variable depth cold planing and of the HMA overlay to obtain the smoothness requirements. Thin sections or additional material quantities may be necessary to meet the smoothness requirements and match adjacent pavement constraints. Please provide information with respect to what portion of the project design, specifications and plans will be changed or waived and how such changes with be paid for. Regardless of which option is preferred, additional construction working days will be necessary.

Inquiry #7: Since Traffic is not allowed on SAMI, will the state allow Contractor to place SAMI on shoulders and not cover with RHMA in the same since there is no traffic on the shoulders?

Inquiry #8: Please provide either layout sheets and or Ramp Description for each line referenced in the the Summary Of Quantities. For example location 5 has the description EB OFF TO NB 15/ FAIRMONT on addendum 2 sheet #3 X-1.However addendum 2, sheet 26, Location 5 calls out 4 different line designation's for a location that describe's a single ramp.This is only one example as this scenario is repeated for multiple locations. Clarification ie. Ramp Descriptions for each Line Designation in each Location and or Layout sheets are needed to be able to properly quantify and build this bid. Line designations are helpful but without a geographical reference point for each line we have no way of determining where said line is located.
