EXECUTIVE SUMMARY The Satellite Transit System (STS) transports passengers to and from the North and South Satellites. This project is a renewal and replacement of the STS's Automated Train Control (ATC) system. The current ATC system is 20 years old and is at the end of its useful life. This project installs new STS network infrastructure, replaces end of life ATC systems equipment, and updates the ATC with the most current version of the manufacturer's controls software while maintaining passenger service to the North and South Satellites. This authorization allows for the selection and award of an Automated People Mover (APM) consultant contract, the design of a new hardened STS fiber optic network, and the preparation of documents necessary for the procurement, installation and testing of new ATC equipment. After finalizing equipment requirements, and revised estimates, staff will return to Commission for authorization to execute construction and goods and services contracts.

COMMISSION AGENDA Action Item No. 6i Page 2 of 6 Meeting Date: July 14, 2020 The STS Controls Renewal and Replacement Project (CIP 801043) is included in the 2020-2024 capital budget and plan of finance. The project was approved on the 2020 #2 Majority-In-Interest (MII) ballot. JUSTIFICATION This project provides important benefits for continued operations, security, and safety. The STS is the primary conveyance method to move passengers efficiently to and from the Main Terminal to the thirty-five gates in the North and South Satellites. In 2019, the STS carried approximately 28 million passengers. The last major STS upgrade was completed in 2003 under CIP #100783. The current ATC subsystem was installed around 2001 and major components are now either obsolete or at the end of their useful life. The ATC system is an integrated set of computerized hardware, software and networks that safely operate the automatic movements of the train system. The STS will cease to operate without a functioning ATC. Key suppliers and repair facilities have indicated that remaining repair inventories are no longer being manufactured and will be gone within a few years. Action is required now to ensure the STS remains operational before more critical pieces of the ATC become obsolete or irreparable. A catastrophic failure or even a prolonged failure of the STS would significantly impact operations at the Airport. In addition to the obsolescence need for the project, a benefit of updating the controls system software is the flexibility to run an additional set of train cars on each of the STS loops. Each loop currently runs two sets of train cars that can carry a maximum of 3,300 passengers per hour. An additional set or three sets of train cars can carry a maximum of 4,950 passages per loop per hour. After the International Arrivals Facility Bridge is operational, reductions in the number of STS vehicles operating in the South loop may be possible and would free additional vehicles for the North loop. Purchase of additional or replacement STS vehicles is not part of the scope of this project. The Airport will be going through a modeling effort to optimize STS vehicle availability balanced against airline passenger demand. This project scope was informed by the December 2018 STS Audit and Alternatives Analysis study and similar ATC system replacement projects in recent years at San Francisco International Airport (SFO), Dallas Fort Worth International Airport (DFW) and London's Heathrow Airport (LHR). Diversity in Contracting The project team with the Diversity in Contracting Department determined a Women and Minority Business Enterprise (WMBE) participation aspirational goal of six percent for the Design and Automated People Mover Consultant contract.

COMMISSION AGENDA Action Item No. 6i Page 3 of 6 Meeting Date: July 14, 2020 DETAILS This project installs modern and redundant fiber optic and radio networks, replaces end of life ATC systems hardware, and updates the ATC system with the most current version of the manufacturer's controls softwarewhile maintaining passenger service to the North and South Satellites. The project is divided into two distinct phases. The first phase, an enabling project, is the design and construction of new STS network infrastructure; the second phase is the design, installation and testing of the ATC equipment. Scope of Work Phase 1 Design and construction of a new hardened STS controls fiber optic network including conduit, fiber optic cable, server rooms, and supporting electrical infrastructure. Work will primarily be performed within the 1.7 miles of STS tunnels and maintenance support spaces. Phase 2 Design, installation, testing and certification of a new STS train controls system including new ATC software and associated equipment (hardware, servers, computers, radios, networking equipment), STS car retrofits, system testing, certification and decommissioning of the old system. Both phases will require over the ramp busing and passenger wayfinding support. Impacts to Operations The project will have major impacts to operations at the North and South Satellites. Installation, testing and certification of the whole system is expected to take approximately 30 months and will require parts of the STS to be out of service. The current plan is to limit STS service outages to the North and South Satellites to a nightly 6-hour window for a 15-18 month period. Over the ramp busing will be required during outages to maintain access to the North and South Satellites. Impacts are expected to begin late 2022 and run through the end of 2024. Acquisition Methodology The project is predominantly equipment replacement with a supporting construction project to provide new physical network infrastructure. Several types of contracts are expected to include: (1) Consulting services for the Automated People Mover and Design Consultant; (2) Construction; (3) Equipment Procurement; (4) Services for busing and wayfinding support. This request is only for the Automated People Mover and Design Consultant. Seventy-five percent of the overall contracting opportunity is for the purchase, installation, testing and certification of ATC equipment which comes from an Automated People Mover (APM) Template revised June 27, 2019 (Diversity in Contracting). COMMISSION AGENDA Action Item No. 6i Page 4 of 6 Meeting Date: July 14, 2020 system manufacturer. The APM manufacturer is responsible for the design, installation, integration, testing and certification for passenger use. ATC software equipment configuration is proprietary to each APM manufacturer. Staff advertised Request for Information (RFI) 20-3 to determine which suppliers could provide, install and certify a replacement ATC for the STS. Only Bombardier Transportation LTD responded. Pursuant to CPO-6 and RCW 39.04.280 staff plans to utilize a CPO-5 waiver to directly negotiate with Bombardier Transportation for the equipment purchase.

The status quo or delayed implementation options place the STS system replacement beyond 2024 which would significantly increase the risk of system failure and therefore were not considered viable options. At the forecasted rate of use, the STS will reach the end of its expected useful life around 2030; with additional renovation, renewal and replacement expenditures the STS subsystems life may be extended several years beyond that. It is expected that a new STS or an alternate means of travel to and from the North and South Satellites will be required no later than 2034. Airport staff are commissioning a study to look at alternatives and make a recommendation for future passenger conveyance to the North and South Satellites. Alternative 1 Whole STS replacement. This would include replacing the entire automated people mover system: remove all existing systems and replace with yet to be determined new Template revised June 27, 2019 (Diversity in Contracting). COMMISSION AGENDA Action Item No. 6i Page 5 of 6 Meeting Date: July 14, 2020 system that include new cars, new power rail, new power centers, new controls, and integration into the existing facilities footprint. Cost Implications: Cost range $600M to $800M Pros: (1) New 30 year APM System (2) Competed requirement Cons: (1) High Cost (2) Loss of 10 years of STS life (3) STS Service shutdowns (will require months of extensive and continuous shutdown) (4) Full time busing to Satellite Terminals or construction of a new tunnel/bridge (5) Increased risk of failure while planning and designing replacement project. This is not the recommended alternative. Alternative 2 Renewal and replacement of the ATC system to reduce risk of failure. The project justification and description above speak to this alternative. This option provides the lead time required to evaluate new technologies and develop a better understanding of a future SEA facility layout that the new transportation system will integrate into. In this option, the equipment manufacturer is given a 6-hour working window each night. Cost Implications: Cost range $65M to $95M Pros: (1) Maximizes flexibility of STS vehicle Fleet (2) Required for additional passenger throughput (3) Decreases the risk of major disruption to Satellite Services due to failure (4) Ten-year minimum additional useful life of the STS system Cons: (1) Single source negotiations with the STS manufacturer (2) Nighttime STS shutdowns (3) May have limited useful life (10 years), given future airport growth projections. This is the recommended alternative.

ADDITIONAL BACKGROUND The STS was the first inter-terminal Automated People Mover (APM) system in the world and the second operational APM at an Airport. Construction of the STS started in 1969 with passenger service beginning in 1973. The 2003 upgrade of the STS installed twenty-one (21) new vehicles, a more modern ATC system, electrical distribution components, and a new guiderail in the existing STS tunnel complex and was expected to last 30 years. The original power rail and travel path are still in service.
