1.0. Background. The U.S. Army Electronic Proving Ground (EPG), Environmental

Test Facility (ETF), Fort Huachuca, Arizona utilizes several mechanical draft cooling towers through evaporation of water liberating waste heat extracted from 13 cascade cooling condensers located around the building compound. Each tower is equipped to constantly measure and meter chemicals which maintain critical pH, hardness, alkalinity, and conductivity levels within the systems. Low microbial activity, corrosion, scaling and fouling must be kept within precise parameters.

1.1. Objectives. The EPG ETF, Fort Huachuca, Arizona is soliciting proposal for full-service monthly chemical treatments for four cooling tower systems which are listed in

Table 1. Exhibit(s) A thru E below providing the Contractor data of all Four cooling tower systems that will be covered underneath this contract. Exhibits are annotated separately and are incorporated within statement of work.

1.2. Scope. The contractor must meet the following requirements for each of the cooling tower systems listed in above Table 1:

• Conduct initial onsite water testing to determine what treatment is necessary.

• Provide and maintain all chemicals required for general control of scale, corrosion, and microbiological fouling.

• Conduct a minimum of one service call per month beginning TBD March 2026 to TBD March 2027.

• Furnish and apply products to retard scale and corrosion in condensing water system.

• Remove empty chemical containers.

• Furnish and apply biocides as required.

• Check, clean, and calibrate chemical control and feed equipment.

• Check water treatment control equipment.

• Furnish and apply corrosion inhibitor to closed loop(s) (should water loss occur from system(s). Contractor will provide supplemental inhibitor to trat a maximum water loss of 10-percent system capacity).

• Submit written reports describing findings, along with recommendations for any changes required.

• Provide all laboratory analysis of water and necessary technical expertise.

• Clean all and refill chemical tanks.

• Clean and maintain chemical pumps.

• Clean and maintain conductivity and pH control equipment.

• Inspect cooling tower and clean Y strainers.

• Replace any and all filters used in the water treatment systems.

• Provide access to online service reporting, data trending, and operator logs.

• Control of inventory. Storage of chemicals is to be determined.

• Safety training of on-site personnel.

• Guarantee that the present degree of “operating efficiency” of the cooling tower systems listed in table 1 will be maintained while under the contractor program or it will be cleaned at no additional cost to the government.

• One time, annually clean the scale off the cooling towers, clean the basins and distribution nozzles.

1.3. Tasks. The contractor will provide service to the cooling towers in accordance with the statement of work (SOW) located at the Environmental Test Facility (ETF)

Compound.

1.4. Delivery.

• Deliverables: Monthly water treatment reports describing findings, along with recommendations for any changes required. The report can be delivered electronically via email. Report should be delivered within 24-hours of service completion.

• Delivery time: Each month following the monthly service call.

1.5. Government-Furnished Property, Material, Equipment, or Information (GFP, GFM, GFE, GFI)

The government will provide:

1. Fully functional chemical feed or control equipment.

2. Replace or repair equipment based on contractor recommendations.

3. Personnel to assist in daily minor operations.

1.6. Installation Access. Access to U.S. installations, buildings and controlled areas is limited to personnel who meet security criteria and are authorized. Failure to submit required information/data and obtain required documentation or clearances will be grounds for denying access to U.S. installations, buildings and controlled areas. The Contractor shall ensure that any subcontractors used in performance of this contract complies with these requirements and that all employees, of both the Contractor and any subcontractor utilized by the Contractor, are made aware of and comply with these requirements. The Contractor shall be aware of and comply with the requirements associated with Installation Access Control.
