STATEMENT OF WORK

Background:

The North Florida/South Georgia Veterans Health System has a requirement to replace chilled water (CW) pumps #1, 2, and 3, the associated variable speed drives, isolation and check valves and install a closed loop water treatment system for the A-wing CW plant.

CW Study conducted by AKEA in OCT20-FEB21 utilizing PIPE-FLO hydraulic analysis shows that the A-wing CW pumps are inadequate. Existing pumps have only 95 feet of head, the model calculations show a requirement for 170 feet of head. All three (3) CW pumps need to be changed from 50HP to 100 HP to provide required flow of 4905 GPM with 170 feet of head. Will require replacement of associated isolation valves, strainers and check valves as well.

Additionally, this provides an opportunity to provide a chemical free closed loop water treatment system to the A-Wing CW plant. Increase in pump size and associated piping and valves is required to increase chilled water flow in Building 1 of the main hospital to correct flow deficiencies throughout the chilled water system determined during the study.

Objective:

A qualified contractor must be brought in to replace existing 50 HP CW pumps 1, 2 and 3 with

100 HP pumps. Additionally, remove and replace existing isolation and check valves, strainers and variable speed drives. Install a closed loop, chemical free, water treatment system.

Connect the variable speed drives to the Desigo BAS
