Public Safety DAS Upgrade
Item No. 8c_supp Meeting Date: March 26, 2024 Public Safety Distributed Antenna System (DAS) Upgrade C801238 | N06489 Trevor Emtman AV-PMG Project Scope BDA-Bi-Directional Amplifier • Provides in-building public safety and critical radio coverage to responders at SEA. • DAS is beyond useful life and needs upgrade to digital and modular design. 2 Project Justification • Failure can result in loss of radio coverage impacting life-safety and emergency communication. • Modern equipment can carry multiple frequency range such as 700/800MHz, VHF spectrum, FirstNet Band 14, & LTE. • Compliance with NFPA-72 & 1225 and fire protection improvements. • RAC requires a redundant radio coverage system in case of single feeder failure. • Wireless coverage testing to determine deficiencies. 3 Schedule 2024 2025 2026 2027 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 PLANNING CX Design SD EXECUTED DESIGN CONSTRUCTION CX Construction Substantial Completion 4 Risks = High = Medium = Low Risk Impact Probability Mitigation Plan Lead Time to Delivery: This is the current lead time to delivery expected 16 weeks - Fiber optic cables as of Q2, 2023. It is expected to go down as the 12 weeks - Wireless equipment project progresses towards construction. CIBS communication rooms are not 2-hour DAS project is not expected to bring comm rooms fire rated. to 2-hr fire rating. Coordinate with AV F&I and POSFD on this risk as the project progresses. AV F&I and POSFD are working on a solution to make all comm rooms to be 2-hr fire rated for continuous fire rating. 5 Cone of Certainty W e are here 6 Requesting • Commission authorization for $10,976,000 to complete design, construction, and closeout phases of this project. • Approval to increase the project budget to a total estimated $11,226,000. 7 Requested Authorization Authorization Project Phase Amount Previous Authorizations Notebook + Survey $250,000 Current request for Authorization Design + Construction + Closeout $10,976,000 Total authorizations, including this Notebook + Survey + Design + $11,226,000 request Construction + Closeout Remaining amount to be authorized N/A $0 8 QUESTIONS? 9
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.
