HomeMy WebLinkAboutA012 - Resolution approving preliminary plans & specs for 2026/27 Airport Airside Improvements Project (Reconstruction of Runway 01/19)ITEM #:13 DATE:06-09-26 DEPT:PW SUBJECT:2026/27 AIRPORT AIRSIDE IMPROVEMENTS (RECONSTRUCT RUNWAY 01/19) COUNCIL ACTION FORM BACKGROUND: The Capital Improvements Plan (CIP) includes the Airport Airside Improvements program, which provides for the reconstruction of Runway 01/19 and associated airfield improvements at the James Herman Banning Ames Municipal Airport. The project is programmed in FY 2025/26 and FY 2026/27 and represents a major airfield infrastructure investment intended to maintain long-term operational reliability, safety, and compliance with Federal Aviation Administration (FAA) design standards. Runway 01/19 is the primary runway at the Airport and has reached a condition where full reconstruction is needed. The existing pavement has a Pavement Condition Index (PCI) score of 45 out of 100 and is in need of full replacement. On April 8, 2025, the City Council approved a Professional Services Agreement with Bolton & Menk, Inc. for design, FAA coordination, construction phasing, bidding documents, and grant administration services associated with the project. On September 9, 2025, the City Council accepted an FAA Airport Improvement Program (AIP) grant agreement in the amount of $1,140,095 to fund the design phase of the project. At the May 26, 2026 City Council meeting, staff provided an informational update regarding the anticipated two-part FAA construction grant process, phased Notices to Proceed, construction sequencing, runway closure impacts, and the planned approach for bringing the project forward for bidding and future grant consideration. No action was requested with that report; it was instead intended to make the City Council aware of the unusual grant timing and phased project delivery strategy before formal action on the project. (Note: A copy of the report has been attached for reference.) The project includes full reconstruction of Runway 01/19 and associated airfield improvements, including portions of taxiways, lighting, drainage, grading, signage, and pavement markings necessary to maintain FAA design standards and long-term operational functionality. The runway is being designed to support regular use by larger business jet aircraft and to accommodate aircraft operations up to approximately 100,000 pounds without special operating restrictions. The project also includes work associated with airfield navigational aids . Although these NAVAIDs are owned and operated by the FAA, the FAA requires the Airport owner to reimburse FAA staff costs associated with project-related work on these facilities. These reimbursement costs are eligible for FAA grant participation as part of the project. 1 Although the Airport Master Plan conceptualizes a future extension to Runway 01/19, no runway extension is included as part of this project. However, the improvements are being designed to accommodate potential future extension considerations without jeopardizing the current investment. The FAA has indicated that construction funding is anticipated to be awarded through two separate grants over two federal fiscal years. The project specifications and contract documents have been prepared with phased Notices to Proceed (NTPs) tied to anticipated FAA grant authorizations. This approach is intended to limit the City’s financial exposure while ensuring that each authorized portion of work results in a usable unit of work and does not leave the runway in an unusable condition if grant timing changes. Preparatory work and drainage improvements are anticipated to begin in late 2026 without runway closures. Major runway paving and runway closure activities are anticipated during calendar year 2027, with Runway 01/19 anticipated to be closed from April through October 2027 and Runway 13/31 anticipated to be closed from July through September 2027 during runway intersection reconstruction activities. Remaining restoration and closeout activities are anticipated to extend into 2028. The Engineer ’s Opinion of Probable Cost for the construction work to be bid is $24,415,000. The total construction phase project cost, including professional services and FAA reimbursement costs, is estimated at $27,980,000. Final project costs will be dependent upon bid results and FAA participation eligibility. The FY 2024/25 Capital Improvements Plan included a standalone Airport drainage improvement project with an estimated cost of $250,000, including $25,000 from the Airport Improvements Fund as the local match. During final project development, the FAA authorized these drainage improvements to be incorporated into the Runway 01/19 Reconstruction Project as eligible work. As a result, approval of the plans, specifications, form of contract, and estimate of cost for this project will also authorize the reprogramming of the previously budgeted $25,000 Airport Improvements Fund contribution from the standalone drainage improvement project to the Runway 01/19 Reconstruction Project. This action does not increase the overall Airport Improvements Fund commitment previously programmed by the City, but instead allows the drainage improvements to be completed as part of the larger runway reconstruction effort. The project also includes a Bid Alternate A to replace the shelter that houses the precision approach equipment at the end of runway 01/19. The project is anticipated to be funded primarily through FAA Airport Improvement Program (AIP) grants, with local matching funds provided through General Obligation Bonds and Airport Improvement Funds consistent with the adopted CIP.

State Airport Engineer - Iowa 6 ITEM #:40 DEPT:PW May 26, 2026 Staff Report UPDATE ON RUNWAY 01/19 RECONSTRUCTION PROJECT BACKGROUND: Runway 01/19 is the primary runway at the Ames Municipal Airport and has reached a condition where full reconstruction is needed to maintain long-term operational reliability and safety. The existing pavement has a Pavement Condition Index (PCI) score of 45 out of 100 and is in need of full replacement. On April 8, 2025, the City Council approved a Professional Services Agreement with Bolton & Menk, Inc. for project design, FAA coordination, construction phasing, bidding documents, and grant administration. On September 9, 2025, the City Council accepted an FAA Airport Improvement Program (AIP) grant agreement in the amount of $1,140,095 to fund the design phase of the project. The construction and inspection portion of the project continues to be coordinated with FAA staff regarding future construction grant timing and eligibility. This portion of the project is programmed in the City’s Capital Improvements Plan (CIP) in two fiscal years: FY 2025/26 ($10,635,000) and FY 2026/27 ($16,440,000), for a project total of $27,075,000. PROJECT OVERVIEW: The project includes full reconstruction of Runway 01/19 and associated airfield improvements, including certain taxiways, lighting, drainage, grading, signage, and pavement markings necessary to maintain FAA design standards and long-term operational functionality. The runway is being designed to support regular use by larger business jet aircraft, with a proposed pavement section intended to accommodate aircraft operations up to approximately 100,000 pounds without special operating restrictions. This is not an absolute regulatory limit; larger aircraft may still be accommodated on a case-by-case basis when operational conditions, pavement capacity, and airport procedures allow. Although the Airport Master Plan conceptualizes a future extension to the existing length of Runway 01/19, there is no extension included as part of this project at this time. However, the proposed improvements are being designed so that a future runway 1 7 extension could be considered without jeopardizing the improvements included in this project. The future runway profile would continue from the elevations established at the south end of the current reconstruction limits. GRANT APPLICATION AND CONSTRUCTION TIMING: The FAA has indicated that construction funding is anticipated to be awarded through two separate grants over two federal fiscal years. Staff intends to bring preliminary plans and specifications to the City Council for consideration to solicit bids at the June 9, 2026 meeting, with bid results and contract award anticipated for consideration at the July 14, 2026 meeting. Following bid receipt and a conditional award which will be contingent upon FAA grant approval, Staff expects to apply for the first FAA construction grant, with the first grant offer award anticipated in August or September 2026 . The second FAA construction grant application is anticipated after October 1, 2026, with the second grant offer award anticipated in Spring 2027, likely around May 2027. The project is being designed with separate Notices to Proceed (NTP) tied to the applicable FAA grant awards . NTP #1 would authorize preparatory work, drainage, and some runway paving following the first grant offer award in 2026. NTP #2 would authorize the remaining major 2027 construction phases after the second grant authorization is in place. This structure is intended to limit the City’s financial exposure while ensuring that each authorized portion of work results in a usable unit of work and does not leave the runway in an unusable condition. If the second FAA grant offer award is delayed, NTP #2 could also be delayed. This could compress the 2027 construction window, extending runway closure periods later into the 2027 construction season, or require additional work to carry over into 2028. Preparatory work and drainage improvements are anticipated in late 2026 without runway closures. Major runway paving and runway closure activities are planned for calendar year 2027, with Runway 01/19 closed from April through October 2027 and Runway 13/31 closed from July through September 2027. Remaining Phase 3 work, restoration, punch list items, and project closeout activities are anticipated to extend into 2028, including a temporary Runway 13/31 closure in March and April 2028. PROJECT SCHEDULE AND PHASING: The schedule below summarizes the anticipated grant sequence, Notices to Proceed, construction phases, and runway closures. The overall schedule remains dependent on FAA grant timing, annual federal funding availability, issuance of Notices to Proceed, and final approval of the Construction Safety and Phasing Plan. 2 8 Activity Jun 2026 Jul 2026 Aug 2026 Sep 2026 Oct 2026 Nov 2026 Dec 2026 Jan 2027 Feb 2027 Mar 2027 Apr 2027 May 2027 Jun 2027 Jul 2027 Aug 2027 Sep 2027 Oct 2027 Nov 2027 Dec 2027 Jan 2028 Feb 2028 Mar 2028 Apr 2028 May 2028 Bid Opening Grant Application #1 Grant Offer #1 Award NTP #1 Grant Application #2 (earliest submittal) Grant Offer #2 Award NTP #2 Phase 1 Preparatory Work Phase 1 Major Construction Phase 2 Intersection Work Phase 3 Work Punch List / Final Restoration Runway 01/19 Availability Runway 13/31 Availability Legend: Bid / Grant Application / Grant Offer Notice to Proceed (NTP) Potential Grant Offer Window Construction Activity Runway Open Runway Closed Phase Description Phase 1 Preparatory Work Limited preparatory work in late 2026, including select storm sewer, grading west of Taxiway A, and northeast access improvements. This work is anticipated to occur without runway closures. Phase 1 Major Construction Major Runway 01/19 reconstruction work excluding the Runway 13/31 intersection area. Runway 01/19 would be closed during this phase while Runway 13/31 remains open. Phase 2 Runway 01/19 and Runway 13/31 intersection reconstruction. This phase requires closure of both runways and represents the most critical operational closure period. Phase 3 Remaining work outside the Runway 01/19 Runway Object Free Zone, including Runway 13/31, taxiway, lighting, signage, pavement marking, shoulder, and tie-in improvements. Runway 01/19 is anticipated to be open, with Runway 13/31 temporarily closed again in March and April 2028. Punch List / Final Restoration Final punch list, restoration, and project closeout activities anticipated in 2028, with only single-runway closures expected as needed. STAFF COMMENTS: No action is being requested of the City Council with this report. This update is intended to provide notice that construction funding is anticipated to be awarded through two separate FAA grants and that the construction plans and specifications are being prepared with phased Notices to Proceed to address FAA grant timing. Staff continues to coordinate with Bolton & Menk and regional FAA staff regarding final design, construction phasing, operational impacts, and funding strategy. The current schedule reflects 3 9 anticipated FAA grant sequencing and available federal funding levels while attempting to minimize impacts to airport users, tenants, and Fixed Base Operator (FBO) operations. Runway 01/19 is anticipated to be closed from April through October 2027. Runway 13/31 is anticipated to be closed from July through September 2027, including the runway intersection work. During the runway-runway intersection work, both runways will be closed, resulting in a full closure of Airport flight operations. Outside of that full- closure period, the phasing is intended to maintain limited Airport operations where feasible, although operations will be constrained by runway, taxiway, and construction area closures. Runway 13/31 is also anticipated to be temporarily closed in March and April 2028 for remaining Phase 3 work. The construction contract is anticipated to use multiple Notices to Proceed tied to FAA grant authorizations. Staff intends to maximize eligible work included in the first grant offer to the extent feasible, while maintaining the phased NTP structure to preserve operational flexibility, minimize financial exposure to the City, and keep the Airport functional as work progresses. FAA staff has informed City staff that the current intent is to award a second construction grant for the remaining eligible runway project costs. While City staff believes the risk is low, the second grant could be delayed or not awarded as anticipated. The plans and specifications are being prepared so each authorized portion of work results in a usable unit of work and the Airport can be left in a functional condition if grant timing changes. A delay in the second grant could compress the 2027 construction window, extend runway closure periods later into the season, or require additional work to carry over into 2028. This strategy is intended to allow authorized work to proceed while limiting the City’s financial exposure if the second grant is delayed or not awarded as anticipated. The City Council will have additional opportunities to consider project approvals, award actions, grant agreements, and any necessary project adjustments at future meetings. Staff will continue coordination with airport tenants, FAA representatives, emergency service providers, and other stakeholders as the project advances toward bidding and construction. Additional updates will be provided as project milestones are reached, FAA funding commitments are finalized, and construction phasing details continue to develop. No action is being requested from the City Council at this time. However, because of the unusual nature of a two part grant process, staff wants the City Council to be aware of the planned approach prior to being asked to take action on the first grant submittal.
