Refer to Section 12-4.02C(3)(o). The roadway must be kept open. The contractor may open the incomplete roadway during construction operations. You are responsible for providing a safe, traversable surface including grading, repairs, dust control, and ramping. See Addendum #1. Response date: 08/23/2021
Specification No. 19 Earthwork
Specs call for additional 3' of compaction outside the paved area, the plans are only showing this at the petromat stations, does this additional 3' also take place outside the CCPR areas as well?
Please clarify. (RFC 28446 submitted 8/17/2021)
No. The sections have different shoulder prep requirements. Response date: 08/23/2021
When does the County anticipate this project to start? Is the County going to suspend the start of the project until spring of 2022? (RFC 28448 submitted 8/17/2021)
This project is anticipated to start 30 days after award. You may request a suspension of work if weather or other conditions interfere with work. Response date: 08/23/2021

The details are general and are to be followed based upon existing conditions. Response date: 08/23/2021
Please clarify what Item 48, Class 2 Aggregate Base, is intended to be for. (RFC 28454 submitted 8/18/2021)
The quantity for Agg. Base was included as part of dig outs. It has been removed from the quantities. Please refer to Section 39-3.02 for replace asphalt concrete surfacing. See Addendum #1. Response date: 08/23/2021
Specification No. Section 30
Item #21 Imported Aggregate is not shown anywhere on the plans. Will the County please provide additional information on where this item is to be placed and what specific requirements there are for this material, Gradation, compaction, etc? (RFC 28472 submitted 8/19/2021)
The existing shoulders are native soil and the material is proposed to be replaced with Cold Recycled Pavement in lieu of base. Imported Aggregate is included to supplement where there is an insufficient RAP quantity. See Addendum #1. Response date: 08/23/2021
Specification No. 19-9.02
per this section, the contractor is allowed to use the dirt/native soil coming from the road excavation operations for the shoulder backing, is the contractor expected to screen this material prior to reusing it? (RFC 28474 submitted 8/19/2021)
Yes. Material must pass the limits in the section. See Addendum #1. Response date: 08/23/2021

Yes, the onsite hauling should be prevailing wage. Response date: 08/23/2021
Specification No. 30-7.03C(2)
Section 30-7.03C(2) states that the cold-planing machine must have a 12 foot minimum wide cutter. This equipment specification is typical of a Cold In-Place Recycling project that is recycled using a train set up. As this project is utilizing a centralized plant location instead of a recycling train is it acceptable to utilize mills with a smaller cutter to preform the initial milling of the roadway? Using a 12-foot cutter would make it difficult or impossible to ensure that the entire roadway is milled, considering there will be corners, edges, and detail milling which must be done using smaller mills. (RFC 28478 submitted 8/19/2021)
The minimum cutter width requirement has been removed. See Addendum #1. Response date: 08/23/2021
Specification No. 30-7.03D(3)
Section 30-7.03D(3) States that RAP shall be crushed and screened to a maximum size of 1" and section 30-7.02D states that RAP must be processed by mechanical means to pass a 1.5" sieve. Can you clarify what the maximum allowable gradation is for this project? (RFC 28479 submitted 8/19/2021)
The maximum allowable gradation is 1". See Addendum #1. Response date: 08/23/2021
Specification No. 30-7.03D(7)
Section 30-7.03D(7) States that cement is to be added into the recycling process at the mill head as a slurry or added directly into the pug mill as a slurry. Section 30-7.01C(6) states that cement may be introduced directly into the pugmill by weight of RAP. Can you please verify that introducing dry Type II/V cement directly into the pugmill by weight of RAP is an acceptable method to introduce the cement into the recycling mixture? (RFC 28480 submitted 8/19/2021)
Either dry cement or slurry is acceptable. See Addendum #1. Response date: 08/23/2021
