Total Project Cost: $4,555,238 Bonds Est. State and Local Taxes: $254,000 ACTION REQUESTED Request Commission authorization for the Chief Executive Officer to advertise for bids, award and execute a major works construction contract for the Combined Communication and Command Center (C4) Power Supply System Improvements project at Seattle-Tacoma International Airport. This authorization is for $2,219,238 for a total authorization of $4,555,238. SYNOPSIS This project will replace the obsolete and failing C4 Uninterruptible Power Supply (UPS) System. The existing system is no longer supported by the manufacturer and replacements parts cannot be sourced. The C4 UPS system provides power to a variety of life-safety, security, and operationally critical applications. These include the 911 Center, the Airport Communications Center, and the 800MHz Radio System, which provides airport-wide communications for Port of Seattle Police, Fire Department, Maintenance, and Airport Operations. This project will replace end of life batteries, upsize the current UPS and batteries system by 50% to meet future demand, and add system power feed redundancy to increase reliability and maintainability. This project was included in the 2016-2020 capital budget and plan of finance. BACKGROUND The 911 Center requires a UPS system to maintain certification as an Association of Public- Safety Communication Officials (APCO) 911 Center. The existing C4 UPS power distribution system is obsolete, near full capacity, and functionally deficient. The system includes two battery banks and two UPSs to provide redundancy, but we have experienced failures in both UPSs and both battery banks due to the UPSs and batteries being beyond their useful lives. Template revised May 30, 2013. COMMISSION AGENDA Ted Fick, Chief Executive Officer February 16, 2016 Page 2 of 6 Recent tests revealed one of the existing battery banks was dead; it was replaced as an expense item (approximately $200,000) to keep the system functional until the entire system can be replaced by this project. The existing batteries operate at a voltage that is not an industry standard; therefore, the replacement batteries may not be able to be incorporated into the system upgrade. The temporary replacement batteries will be surplused. The automatic power switching system does not function properly and cannot be corrected through repair. C ritical parts are no longer available and crucial equipment suppliers have gone out of business. The system also lacks redundant power paths to allow portions of the system to be de-energized for maintenance and repair without affecting critical airport operations. This project corrects all the C4 UPS deficiencies and provides 50% more capacity to accommodate growth. Breakdowns for this system are becoming increasingly frequent. PROJECT JUSTIFICATION AND DETAILS Project Objectives The project objective is to increase the reliability of the C4 UPS Power Distribution System by replacing obsolete equipment, eliminating single points of failure, and providing redundant power feeders. This project has been designed to be a highly reliable system to back-up critical life-safety, security, and business critical operations including the 911 Center, Airport Communications Center, and the 800 MHz Radio System. Scope of Work The scope of work for this project includes: Demolish and replace existing UPSs, paralleling cabinets, batteries, Automatic Transfer or Static Switches Provide wiring, testing, commissioning and associated equipment for a fully functional system with no single points of failure upstream of the power distribution units. Add Power Connection Box, Power Monitoring Equipment, Remote Monitoring, and Power System Filters. Provide rack mount automatic transfer switches or replace with static transfer switches (varies depending on final design); and Upgrade fire protection system. Schedule Project Notebook Approval: 4th Quarter 2014 Commission Authorization for Design: 2nd Quarter 2015 Design Start: 2nd Quarter 2015 Design Completion: 1st Quarter 2016 Commission Authorization for Construction: 1st Quarter 2016 Construction: 2nd Quarter 2016 through 2nd Quarter 2017 COMMISSION AGENDA Ted Fick, Chief Executive Officer February 16, 2016 Page 3 of 6 FINANCIAL IMPLICATIONS Budget/Authorization Summary Capital Expense Total Project Original Budget $2,052,000 $0 $2,052,000 Budget Increase (September 2014) $2,154,471 $348,767 $2,503,238 Revised Budget $4,206,471 $348,767 $4,555,238 Previous Authorizations (Original Scope) $1,987,233 $348,767 $2,336,000 Current request for authorization $2,219,238 $0 $2,219,238 Total Authorizations, including this request $4,206,471 $348,767 $4,555,238 Remaining budget to be authorized 0 0 Total Estimated Project Cost $4,206,471 $348,767 $4,555,238 Project Cost Breakdown This Request Total Project Design $498,238 $1,330,238 Construction $1,721,000 $2,971,000 Sales Tax $0 $254,000 Total $2,219,238 $4,555,238 Budget Status and Source of Funds This project, C800107, was included in the 2016-2020 capital budget and plan of finance at an estimated cost of $4,555,238. This project previously received project-wide authorization in 2007. The C4 UPS System was redesigned at that time, but a decision was made to delay moving forward with construction due to budget constraints resulting from an economic downturn. It has been determined that only 30% of the previous design work is now usable. Consequently, $348,767 was written off to expense in 2014. The amount needed to complete the design is estimated to be an additional $498,238. Given the amount of time that has passed since the original authorization in 2007, staff is returning to Commission to seek authorization to proceed with design and construction. The funding sources include the Airport Development Fund and revenue bonds. Staff is returning to request the construction authorization needed to complete the project. COMMISSION AGENDA Ted Fick, Chief Executive Officer February 16, 2016 Page 4 of 6 Financial Analysis and Summary CIP Category Renewal/Enhancement Project Type Renewal & Replacement Risk adjusted discount rate N/A Key risk factors N/A Project cost for analysis $4,555,238 Business Unit (BU) Admin (costs allocated to all cost centers) Effect on business performance NOI after depreciation will decrease IRR/NPV N/A CPE Impact $.01 in 2017 Lifecycle Cost and Savings The replacement of the existing Uninterruptable Power System will decrease the risk of unforeseen failures of obsolete equipment that can impact critical operations at the Airport; however, the replacement will not appreciably decrease the number of preventative maintenance activities performed on the system. Weekly UPS testing is required for 911 certification. STRATEGIES AND OBJECTIVES This project supports the Port's Century Agenda Objective of meeting the region's air transportation needs at Sea-Tac Airport for the next 25 years. Maintaining our existing assets and infrastructure is necessary to meeting this objective. ALTERNATIVES AND IMPLICATIONS CONSIDERED 1. Status Quo - Do not proceed with the project at this time. Delay replacement as long as possible. Cost Estimate: $0 capital cost in 2016, but increased maintenance expense in near term (approximately $50k per year) and $4.5 million plus escalation to replace system in future. Pros: Defers capital cost to future. Cons: The existing system is no longer supported by the manufacturer and replacements parts cannot be sourced. Port of Seattle may not meet National Fire Protection Association (NFPA) requirements for uninterruptable power supply to back up critical life/safety equipment and functions. The current design may be expensed at a cost of approximately $800,000. Port could lose its 911 certification and would no longer meet inter-local governmental agreements. COMMISSION AGENDA Ted Fick, Chief Executive Officer February 16, 2016 Page 5 of 6 Port and surrounding communities could be left without emergency communications services. This is not the recommended alternative due to the risks identified. 2. Replace obsolete equipment in kind without upsizing or reconfiguring the system to provide redundancy. Cost: $4,064,000 Pros: Saves $491,000 in construction costs. Cons: The current design would be expensed at a cost of approximately $800,000. Contrary to previous commission direction to provided added capacity for growth and system redundancy. Lacks capacity growth for future equipment additions. Less reliable, maintainable and does not eliminate single points of failure. o Failure would take a minimum of several hours and up to several months to correct. Port and surrounding areas left without emergency communications until corrected. This is not the recommended alternative. 3. Upsize and replace equipment in kind, without reconfiguring the system to provide redundancy. Cost: $4,147,000 Pros: Saves $408,000 in construction costs Similar to Alternative 2 above, but this option upsizes the system to meet future demands. Cons: The current design would be expensed at a cost of approximately $800,000. Contrary to previous Commission direction to add system redundancy. Less reliable, maintainable and does not eliminate single points of failure o Failure would take a minimum of several hours and up to several months to correct. Port and surrounding areas left without emergency communications until corrected. COMMISSION AGENDA Ted Fick, Chief Executive Officer February 16, 2016 Page 6 of 6 This is not the recommended alternative. 4. Redesign system and increase reliability by replacing obsolete equipment, increasing capacity by upsizing equipment, and providing redundancy. Cost: $4,555,238 Pros: Construction bid documents are complete Redundant system capable of supporting emergency communications for existing and future critical airport functions in the event of power outage or equipment failure. Cons: Originally the most expensive project alternative; however, since the design is now complete, this is the lowest time and cost alternative that meets Port and NFPA requirements. This is the recommended alternative. ATTACHMENTS TO THIS REQUEST None.
