RFP EQ5P2SS1P-17-0084, Glycol Cooling Tower Replacement, Everett M. Dirksen Courthouse, 219 S.

Dearborn St. Chicago IL 60604.

Amendment 06 is hereby issued to:

1) Respond to the following RFI:

1. The specifications list Aqua-Chem, Inc. as being the sole-sourced chemical treatment contractor. However, drawing MD200 identifies Chem-Aqua as the chemical treatment contractor. Can you please clarify which contractor we are to use for the chemical treatment, and can you possibly provide a contact name and number for that company? Aqua-Chem and Chem-Aqua are both chemical treatment companies and are not one in the same.Can you please confirm the chemical treatment scope of work? The drawings indicate that the contractor is to provide similar equipment for the new cooling tower and that the chemical treatment contractor is to modify piping and controls. The specifications state that chemical feed equipment is existing to remain and the installation procedure states to use existing equipment to add inhibitors, glycol, etc. to the system. No new chemical treatment or equipment is listed in the specifications.

A new chemical treatment system is required for the evaporation side of the new cooling tower to minimize the buildup of scale in the basin water and on the fill.

Chemical treatment in the form of glycol, inhibitors, etc needs to be added to accommodate the addition of fluid and piping to the glycol loop.

Finally, the chemical treatment system for the existing towers on the opposite end of the facility needs to be modified to accommodate the removal of the forced draft tower.

Efforts shall be performed by GSA contracted chemical service provider. Chem-aqua. Please remove any reference to Aqua-Chem.

2. 1.8-A-4 – Please confirm that the warranty period is five (5) years?

A: Please See RFI 23 on Amendment 03 Issued on January 16, 2018.
