Item No. 6d_supp Meeting Date: December 10, 2019 Fire Pump Replacement CIP C800794 Tyler Salisbury AV PMG - Infrastructure Project Scope and Location • Replace four (4) emergency fire pumps - Originally installed in 1970's • Install isolation valves - Single pump isolation for maintenance • Install a flow meter system - Annual in-house certification 2 Fire Pump Replacement Water Tower Fill Supply Loop Boosted supply • • • • Original Building - 1970s (Green) Building expansion and Pump Upgrade - 2000's (Yellow) Isolate and Replace High Flow needs • 19,000 GPM at 110 PSI (Hanger fire) • Minimum of 5 pumps needed to sustain the need 3 Fire Pump Replacement Equipment to be replaced: • Diesel engine • Battery bank • Pump head and shaft • Controller panel • Check valve • Pressure relief valve Install of new equipment: • Isolation valve 4 Flow Measurement Water Tower Fill Boosted supply • Annual Flow Certification • Bypass line • Linear requirements • Inline flow meter system (Direct pressure measurement) • Fill reservoir when testing 5 Schedule • Commission for Design and Construction - 4 Quarter 2019 Alternate Procurement - Building Engineering Systems • Advertise for Bid - 1st Quarter 2020 • Contract Award - 2nd Quarter 2020 • Design Complete - 4th Quarter 2020 • Construction Start - 4th Quarter 2021 • Substantial Completion - 3rd Quarter 2021 6 Project Risks 1. Pump Failure - This project will remove 4 pumps from the 10 existing used as fire protection. If one of the 6 remaining pumps has a significant failure event that takes it out of service the system will only have 5 pumps available. Mitigation - The system is periodically checked to ensure the pumps will operate as needed. Peak load will only require 5 pumps at a minimum to maintain coverage. 2. Competitive market - This project is small in comparison to other projects being advertised. Mitigation - Additional steps are being taken to advertise the solicitation to entice additional 7 Appendix • Alternatives 8 Alternative 1 • Defer replacing the pumps until they are no longer operable. • Cost Estimate: $75,000 would need to be expensed. Pros • This defers the expense to a later date. Cons • This alternative may result in additional costs if the pumps need to be replaced on an emergency need. • This alternative removes the additional capacity if multiple pumps are out of service. • This alternative does not address the need for an inline measurement for annual flow testing. • This alternative does not resolve the isolation issue on the pumps if one in the bank of four needs service. • This alternative will result in an increased maintenance cost to keep underperforming pumps in operation. This is not the recommended alternative. 9 Alternative 2 • Replace 4 pumps only. • Cost Estimate: $4,500,000 Pros • The replacement pumps will have a new service life. • Common equipment for all four pumps. • Reduced maintenance costs. Cons • This alternative requires an outside contractor to certify the pumps annually. • This does not allow for individual isolation of each pump. This is not the recommended alternative. 10 Alternative 3 - Recomended • Replace four fire pumps, install isolation valves, and install a flow metering system. • Cost Estimate: $5,000,000 Pros • This alternative provides the most reliable means to fight a fire. • The alternative replaces four pumps, reducing costs as compared to performing two projects replacing two pumps. • This allows for each pump to be isolated for maintenance. • This will allow the boiler shop employees the ability to re-certify the pumps annually. Cons • This is the highest capital investment 11
