SRCI Complex 1 Hot Water Heater Replacement Background/Statement of Work

Background: SRCI is located at 777 Stanton Blvd., Ontario, Or. and is a multi-security institution representing the largest facility in the department with 2,336 medium security beds, 154 minimum security beds and 510 Special Housing beds. Complex One opened in August of 1991, the original design had one- 250-gallon water heater per housing unit located on the roof. Since, SRCI Physical Plant has added one

ea. additional matching water heater per housing unit to provide more hot water and a backup if one were to go down.

Project: SRCI has 6 250-gallon gas fired 400,000 btu water heaters located on the roof of housing units A, B, And C. These water heaters have reached the end of life and need replacement. Increasing btu input to 800,000 btu’s will give each housing unit redundancy and prolong the life of the new water heaters.

SRCI Complex 1 Hot Water Heater Replacement Scope of Work

The scope of work for this project is to replace the 6 existing 250 gallon 400,000 btu gas fired water heaters with 6 new 250 gallon 800,000 btu gas fired water heaters for SRCI Complex 1 housing units A, B, and C. These water heaters need to have a horizontal mounted NEMA rated control enclosure (reference detail SB-92747-1) while meeting the specs of detail SB- 91833-1. The 18 existing thermostatic mixing valves are to be replaced with new digital mixing vales. Water heaters and tempering valve are to have BACnet capabilities and programmed into SRCI’s Carrier I-Vue building automation system. Each water heater will have a dedicated circuit and new heat trace on all roof top cold water and hot water lines. The panels servicing these water heaters are to be replaced with new service panels as well.

During demo, one existing water heater can provide sufficient hot water to the housing unit. Following Exhibit 7.15 (E) allows the institution to monitor hot water usage. For shutdowns lasting longer than 2 hours, contractor provides temporary hot water heater which will give the ability to replace both water heaters on each housing unit, minimizing crane picks and factory rep start up.
