Runway 10R-28L Rehabilitation Project at Hayward Executive Airport: Approval of Plans and Specifications and Call for Bids
End
RECOMMENDATION
Recommendation
That Council adopts the attached resolution (Attachment I) approving the plans and specifications for the Runway 10R-28L Rehabilitation Project at Hayward Executive Airport project, calling for bids to be received on May 17, 2016.
Body
BACKGROUND
As previously presented at the Council Airport Committee meeting on January 22, 2015, rust resulting from the oxidation of iron minerals in the pavement aggregate is penetrating through the existing runway markings on Runway 10R-28L at the Hayward Executive Airport. This has reduced the contrast between the dark pavement and white paint markings and could create potential unsafe conditions for aircraft using the runway. This project calls for the rehabilitation of the main runway. The proposed improvements will remove the top two inches of oxidized pavement that will be replaced with new asphalt pavement. By carefully testing the new asphalt to confirm that it meets standards, we do not expect a reoccurrence of this problem.
DISCUSSION
Runway 10R-28L is primarily used by jet and turboprop aircraft and is the most critical runway for aircraft approaching the Airport. If oxidation of aggregate in the pavement is allowed to progress, particles could begin to flake and loosen from the pavement surface potentially causing damage to aircraft. A specialist from the Airport’s consultant, AECOM, evaluated the runway and recommended that milling the existing pavement and applying a two-inch asphalt lift with proper mix should alleviate the rust issue. It was determined there are no sealants or other chemical products on the market that can successfully address the rust issue as an alternative to removing the oxidized pavement layer and re-paving the runway.
A key staff objective is to reduce the overall cost of capital projects through the use of grants from local, state or federal government. On September 28, 2015, staff was informed that the Federal Aviation Administration (FAA) had tentatively approved funding in the amount of $1,935,000 to resurface Runway 10R-28L. This was in addition to a grant recently approved by Caltrans in the amount of $499,000 for the same project. To move forward with the FAA grant process, a resolution from Council approving the plans and specification and call for bids must be approved.
This project is categorically exempt under Section 15301(c) of the California Environmental Quality Act Guidelines for the operation, repair, maintenance, or minor alteration of existing facilities.
FISCAL IMPACT
The estimated project costs are as follows:
The estimated funding is as follows:
PUBLIC CONTACT
The public was initially informed of the project and the potential FAA and Caltrans grants in the staff report dated January 22, 2015 to the Council Airport Committee (CAC). Based on input from the Council members of CAC and the public, the Airport Manager subsequently formed an advisory group of airport tenants to provide feedback during the initial planning phase of the project. Two informational meetings with the advisory group were held on May 7, 2015 and March 1, 2016. Pavement experts participated in those meetings and presented options to address the concerns expressed by airport tenants.
The project was also the subject of additional staff reports and public presentations to the CAC on April 23, 2015 and October 22, 2015. The project was highlighted in airport newsletters dated August 2015 and April 2016. The newsletter is distributed to all airport tenants and posted online. Staff will work closely with paving experts and based tenants to minimize runway downtime.
NEXT STEPS
The final schedule will be determined based upon FAA grant approval. Once the bids are received, and a recommendation of award of the lowest responsible bidder is provided to the FAA, the FAA will provide notification of the available funding for this project.
Construction work will include a required sixty-calendar day mobilization and Airport safety training period with the closure of the main Runway 10R-28L for only seven consecutive calendar days as noted below. The completion of the remaining project work will not require runway closures.
The estimated schedule is as follows:
