Okaloosa County BOCC — April 5, 2016 — Approval of the 2016 Overlay List and a Task Order for the 2016 Cold- — agenda request

BOARD OF COUNTY COMMISSIONERS AGENDA REQUEST DATE: April 5, 2016 TO: Honorable Chairman and Members of the Board FROM: Jason Autrey SUBJECT: Approval of the 2016 Overlay List and a Task Order for the 2016 Cold- Mix Road Preservation List DEPARTMENT: Public Works BCC DISTRICT: 1 & 3 STATEMENT OF ISSUE: Public Works staff annually provides a list of existing cold-mix roads proposed for preservation treatments to the Board of County Commissioners for consideration and approval. Traditional roadway overlay work is performed using in-house staff, but alternative preservation techniques used on cold-mix roadways require the services of an outside contractor. This request is for approval of a task order with the County's contractor and the associated 2016 Overlay/Cold-Mix preservation list. BACKGROUND: Asphalt Paving Systems, Inc is the contractor tasked with providing alternative road preservation techniques based upon staff recommended surface treatments. Treatments associated with this contract (C16-2369-PW) are utilized on cold mix roadways with the intent to preserve the existing roadway surface. Inherently, cold mix roadways do not have the service life of traditional hot-mix asphalt roadways; however, utilizing a surface treatment can significantly improve the roadway life at a minimal cost. Work on roadways scheduled to receive a traditional overlay of hot-mix asphalt is performed by in-house staff. Staff evaluates roadways considering the variety of treatment options available from the contractor and/or in-house services. Treatment options available from the contractor include chip seal, double chip seal and fog seal. For a road to be considered a viable option for chip seal or double chip seal, it must be an existing cold mix prepared roadway. Fog Seal treatments are used as the final surface wearing for chip seal and double chip seal methods. Placement of a single or double chip seal is most effective when the road shows minor to moderate loss of stone retention and no indication of a base failure. Chip seals typically do not improve the ride quality (smoothness) of the road, rather this treatment is intended to prevent the road from further deterioration. Application of a fog seal will bind stone further extending the roadway life. These alternative surface treatments extend the life expectancy of the roadway at a significantly lower cost than the traditional overlay. Utilization of these alternatives maximizes the funds allotted for road preservation. This list of roadway segments provided herein identifies candidate road segments for traditional overlay treatments (to be performed by in-house staff) and alternative surface treatments of cold- mix roads. These segments have been identified as those of the most critical need within each district, taking into consideration the funding available. OPTIONS: Approve/Disapprove Task Order 1 and the associated overlay/cold-mix road preservation list. RECOMMENDATIONS: Request approval of Task Order 1 for the not to exceed amount of $174,111.11 to Asphalt Paving Systems, Inc. under contract C16-2369-PW and approval of the associated 2016 road resurfacing list.
