8a. Remote Aircraft Deicing Memo
COMMISSION AGENDA MEMORANDUM Item No. 8b ACTION ITEM Date of Meeting August 13, 2019 DATE: August 5, 2019 TO: Stephen P. Metruck, Executive Director FROM: Jeffrey Brown, Director, Aviation Facility and Capital Program Daniel Zenk, Interim Director, Airport Operations Wayne Grotheer, Director, Aviation Project Management Group SUBJECT: Remote Aircraft Deicing (CIP #C801035) Amount of this request: $2,850,000 Total estimated project cost: $24,300,000 ACTION REQUESTED Request Commission authorization for the Executive Director to design and prepare construction bid documents for the Remote Aircraft Deicing project at the Seattle-Tacoma International Airport in an amount not to exceed $2,850,000 of a total estimated project cost of $24,300,000. EXECUTIVE SUMMARY This project will mitigate some of the delays caused by on-gate deicing, by constructing the infrastructure to provide two off-gate deicing positions on Taxiway A. Over the past few years, the airport has experienced rapid growth in both passenger and aircraft operations. The increased aircraft operations has created an aircraft gate deficiency and resulted in significant departure delays when aircraft on-gate deicing occurs. The on-gate deicing also requires arriving aircraft to hold for gates on the airfield, further congesting the movement area and exacerbating delays. Based on input from the Federal Aviation Administration Air Traffic Control Tower, aircraft departures during deicing operations could increase significantly with the addition of the proposed off-gate deicing positions that will be constructed on Taxiway A. The Remote Aircraft Deicing CIP #C801035 is not included in the 2019-2023 capital budget and plan of finance. A budget was transferred from the Aeronautical Reserve CIP (C800753) resulting in no net change in the total Aviation capital budget. Template revised January 10, 2019. COMMISSION AGENDA Action Item No. _8b__ Page 2 of 6 Meeting Date: August 13, 2019 JUSTIFICATION Based on the Bureau of Transportation Statistics data, Alaska Airlines had 296 hours and Delta Airlines had 392 hours of weather delay during the 2017/2018 and 2018/2019 winter seasons. The significant delays and inconvenience to the traveling public have caused negative traveling experiences. This project will mitigate some of the delays and support the strategy of the Port's Century Agenda objective to "Advance this region as a leading tourism destination and business gateway" by meeting the region's air transportation needs at the airport for the next 25 years. The construction of the two off-gate deicing positions will result in less aircraft holding for a gate on the airfield, or congesting the movement area, which will increase passenger level of service, reduce the long-term operating cost of the airlines, and support the long-term strategy of the Port's Century Agenda objective to "Bethe greenest, and most energy efficient port in North America" by reducing air pollutants and carbon emissions. In addition, less overall deicing fluid use is anticipated due to the higher efficiency of deicing on Taxiway A, supporting the King County Waste Water Permit agenda of reducing industrial waste water. Due to the rapid growth of aircraft operations, locations in the non-movement area that could accommodate off-gate deicing are increasing being utilized for other purposes such as hardstand operations, Remain-over-night (RON) parking of passenger aircraft, and cargo operations. The rapid growth of hardstand operations and competing uses has effectively eliminated the availability of these hardstands in the non-movement area for deicing operations. Projects included in the Sustainable Airport Master Plan (SAMP) Near-Term Projects (NTP) and currently in environmental review would resolve the existing deicing deficiency by adding additional gates and new multi-use hardstand positions in the non-movement area for off-gate deicing. If these projects received required approvals through the environmental review process, they will take several years to implement and interim solutions are needed now to alleviate the growing delays experienced during deicing operations. As part of SAMP, Taxiways A and B may be relocated to meet the 500-foot separation criteria from the runway. Should this portion of SAMP NTP be implemented, it would shorten the off-gate deicing project service life to approximately six to ten years from construction completion. Diversity in Contracting Project staff is working with the Diversity in Contracting Department in outreach to woman and minority business enterprises (WMBE) of this opportunity, and the establishment of the WMBE aspirational goal for this construction project. DETAILS During the 2017/2018 and 2018/2019 deicing season, two narrow body deicing positions were tested in the movement area at the north end of Taxiway A. The test helped mitigate some of the delays caused by the on-gate deicing without incident. With the addition of the two off-gate Template revised September 22, 2016; format updates October 19, 2016. COMMISSION AGENDA Action Item No. _8b__ Page 3 of 6 Meeting Date: August 13, 2019 deicing positions provided by this project, an Operational Safety Assessment was conducted with the FAA, Airlines, and Airport Operations in July 2019 to identify hazards and document mitigations to ensure safe airfield operations. This project will be constructed in 2020 between late summer and end of November to avoid the peak travel months and minimize operational impacts. A cross-over taxiway located north of Taxiway G will be constructed between Taxiways A and B to alleviate queueing back-ups during deicing operations. N ew asphalt pads for deicing equipment will be constructed along Taxiway A. Phased closures of sections of Taxiway A and Taxiway B will be needed for construction with the probable closure of Runway 16L/34R when operationally required for airfield traffic optimization. Construction phasing plan will be developed to minimize the impacts from construction to airfield operations. A Construction Safety Risk Management Panel will be conducted during project design with Airlines, FAA, and Airport Operations to ensure safe and efficient airfield operations during construction. A project labor agreement was evaluated in collaboration with Port of Seattle Labor Relations and will be used based on the location and complexity of this project and the importance of labor continuity and stability to minimize the operational impacts during construction. Scope of Work The main scope items are listed as follows: (1) The construction of a cross-over taxiway to alleviate queueing back-ups during deicing operations on the taxiways (2) Partial reconstruction of portions of Taxiway A and Taxiway B pavement and lighting infrastructure (3) The construction of asphalt pads along Taxiway A for Deicing Equipment (4) Industrial Waste and Storm Drainage System Improvements Schedule Activity Commission Design Authorization 2019 Quarter 3 Design start 2019 Quarter 3 Commission Construction Authorization 2020 Quarter 2 Construction start 2020 Quarter 3 In-use date 2020 Quarter 4 Template revised September 22, 2016; format updates October 19, 2016.

A budget was transferred from the Aeronautical Reserve CIP (C800753) resulting in no net change in the total Aviation capital budget. Given that the life of the asset would be six to ten years, the planned funding source will be 2020 revenue bonds with a short amortization to more closely match the life of the asset (ten years). The project was presented to the Airline Airport Affairs Committee (AAAC) on June 27, 2019. The majority-in-interest ballot will be submitted to AAAC in August. Financial Analysis and Summary Project cost for analysis $24,300,000 Business Unit (BU) Airfield Movement Area Effect on business performance (NOI after NOI will increase after depreciation depreciation) IRR/NPV (if relevant) N/A CPE Impact $0.22 for 6-year life or $0.15 for 10-year life Future Revenues and Expenses (Total cost of ownership) The design life for the various pavements will need to meet the minimum FAA design criteria, likely 20 years. Those assets that are likely to remain in service beyond possible SAMP implementation would be designed for 40 years or longer.
