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
