9b Presentation Main Terminal Infrastructure Upgrades
Item No. 9b_supp Meeting Date: September 22, 2020 Main Terminal Infrastructure Upgrades History Main Terminal built in 1970s North Extension added in 1980s South extension added in 2000 All code requirements met at time of renovations Background Code did not require sprinklers Projects have upgraded spaces as work is completed Inefficient, and doesn't address the full issue No longer viable option going forward Entirety of the building must have fire sprinklers Limited ability for future construction until this project is started Project Purpose Upgrade the Main Terminal to meet current fire & building code Improve passenger safety by upgrading several life safety systems New, reliable means of providing emergency power for a majority of the airport Remove a large amount of asbestos fireproofing and other asbestos containing materials 4 Fire Sprinklers - Scope Install new fire sprinklers throughout the Main Terminal (Ticketing, Esplanade, Mezzanine, and Baggage Claim) and above both the departure and arrivals drives Add additional fire standpipes to meet current code 5 Ceiling and Lighting - Scope Replace existing ceiling that is no longer manufactured while installing new systems Replace existing lighting with new energy efficient LEDs New emergency exit signage and new signage that is hung from the ceiling 6 Asbestos Removal - Scope Significant amounts of asbestos fireproofing remain in the Main Terminal Reduces overall removal cost by doing it all at once instead of spot abatement Removal reduces cost and time required to conduct maintenance of systems 7 Smoke Control & Emergency Power - Scope Install new smoke control exhaust Replace the existing emergency power generating system Outdated Unable to meet the new load of the smoke control system System supports Concourse B, C, and D; Main Terminal; C1; and SSAT New fire doors on the terminal side of skybridges 8 Project Impacts to Operations Critical to manage impact to passenger movement in the Main Terminal Multiple phases of construction Scaffolding required to perform work Limited laydown areas, especially with social distancing needs 9 Risks Total emergency power need unknown Unknown location for generators Unknown exhaust routes and requirements for smoke control Budget Initial Budget: $350,000,000 Current Range: $300,000,000 - $400,000,000 The number of phases required, complexity of work, and need to minimize passenger impacts increases cost. Overall duration of the project. 11 Preliminary Design Objectives Design smoke control system for the Main Terminal and Concourses B, C, and D to determine emergency power load requirements Evaluate means and methods of replacing the emergency power generating system Evaluate ways to minimize passenger impacts Provide estimate for project budget 12 Next Steps October 2020 - Request Commission Authorization for Preliminary Design December 2021 Complete Preliminary Design Q1 2022 Update Commission on findings of preliminary design and request full design funding 13 Questions 15
Limitations of Translatable Documents
PDF files are created with text and images are placed at an exact position on a page of a fixed size.
Web pages are fluid in nature, and the exact positioning of PDF text creates presentation problems.
PDFs that are full page graphics, or scanned pages are generally unable to be made accessible, In these cases, viewing whatever plain text could be extracted is the only alternative.
