Item No. 10b_supp Meeting Date: July 27, 2021 Satellite Transit System (STS) Controls Renewal and Replacement Procurement and Construction Authorization Seattle-Tacoma International Airport The STS Moves Public to Airport's N & S Satellites Design and construction: 1969 - 1972 Last major upgrade: 1999 - 2003 2nd Airport APM in the World 6 Stations with 1.7 Miles of track Carried 28 Million Passengers in 2019 Replacement System needed by 2034 Project Purpose Renewal and replacement project for the STS's Automatic Train Control (ATC) sub-system and associated software, hardware & networks Reduces risk by replacing critical 20-year-old end of life & obsolete components Optimizes STS system capacity by allowing increased passenger throughput System recovery time improved STS Controls Project Scope Construction Goods & Services Phase I Phase 2 ATC System - Software - Hardware - Network - Radios - Certification Fiber/ Electrical Infrastructure VATC X 21 Cars Customer Experience Planning for STS shutdowns from 11PM to 5 AM Dedicated Wayfinding Staff Contracted Bus Support 5 Risks and Operational Impacts RISK DESCRIPTION PROBABILITY IMPACT MITIGATION PLAN Safety Safety is the utmost priority. An exposed Low High Both vendors and contractors will be 600V power rail, limited working area and required to adhere to stringent safety driverless moving train cars pose significate protocol for access and working within dangers to workers within the STS tunnels. the STS tunnels. Extended STS outages Major impacts to Satellite operations with Medium High Busing will be provided for STS outage extended STS outages periods. The current controls system will remain in place until the new system is completely tested and certified for passenger service. Procurement method The Controls System is proprietary to the Medium Medium The Port is utilizing a Specialist (single supplier STS Manufacture. Staff issued a sources Automated People Mover Consultant to negotiations) sought RFI to determine that only develop scope and pricing documents Bombardier Transportation could provide to evaluate pricing. Staff is analyzing the replacement controls. recent Controls Upgrades from other Public Owners. 6 Project Timeline 2020 2021 2022 2023 2024 Long APM Develop ATC D ATC Design Lead ATC Installation & Testing Consultant Bid Package Items C Phase 1 Phase Design Const.
