This Performance Work Statement (PWS) outlines the requirements for a non-personal services contract to provide water treatment chemicals, equipment, and associated technical services for boilers, cooling towers, and circulated hot/chilled water systems at Aberdeen Proving Ground (APG) in Maryland. The contractor is responsible for providing all necessary personnel, transportation, and materials to control scale, corrosion, and biological growth (such as Legionella) across six designated Government locations. Key technical requirements include weekly water testing, bi-weekly reporting, adjusting blow-down and water softener controls, performing chemical cleanings, managing equipment layups, and providing specialized amine treatment for the Edgewood steam lines. The contractor must also conduct annual training for Government staff, participate in annual business reviews, and review engineering plans for new facility projects. Contract administration is overseen by the Contracting Officer (KO) and Contracting Officer’s Representative (COR). The contractor must submit a Quality Control Plan (QCP) and a comprehensive transition plan within ten business days of award. Staffing requirements mandate a qualified, English-speaking Project Manager available 24/7, and on-site water treatment support personnel with at least five years of relevant experience. Additionally, all contractor personnel must comply with rigorous installation security policies, vehicle registration, and safety/environmental regulations.

This Quality Assurance Surveillance Plan (QASP) outlines how the government will monitor and evaluate contractor performance for the HVAC Water Treatment Contract at Aberdeen Proving Ground (APG). Its primary purpose is to ensure the contractor meets the standards specified in the Performance Work Statement (PWS). The plan defines the roles of key government personnel, including the Contracting Officer (KO), Contracting Officer’s Representative (COR), and Technical Monitor (TM). While the contractor is solely responsible for implementing its approved Quality Control Plan (QCP), the government will use specific surveillance methods—such as 100% inspection, customer feedback, periodic inspections, and task output observations—to monitor compliance. Contractor performance will be rated as Very Good, Satisfactory, Marginal, or Unsatisfactory. If the contractor fails to perform, the government can issue cure or show-cause notices, withhold a percentage of monthly payments, or terminate the contract for default. The Performance Requirements Summary (PRS) table details four critical service areas requiring 100% inspection with a 0% allowable deviation: 1. Submitting weekly written boiler reports bi-weekly. 2. Testing and reporting cooling tower circulating water weekly. 3. Conducting closed-loop system checks to maintain pH, nitrite, and biological limits. 4. Developing and maintaining an approved QCP. Non-conformance in these areas will lead to formal discrepancy reports, potential negative CPARS ratings, and payment reductions.

This document outlines the official site visit schedule for the HVAC Water Treatment Contract solicitation at Aberdeen Proving Ground, Maryland, scheduled for September 3, 2026. The purpose of the site visit is to tour various boiler and chiller plants. The document identifies key government attendees, including Army Contracting Command (ACC) contracting officers and specialists, alongside several Contracting Officer's Representatives (COR) from the Department of Public Works (DPW) Operations and Maintenance Division (OMD). The itinerary details a structured timeline starting at Building 4304 and includes tours of the 345 Boiler Plant, followed by sequential site visits and travel windows to Buildings 4119, 4219, 4312, and ending at Building E4404.

This document is a federal pricing schedule and bidding sheet for water treatment chemicals and on-site support services. It outlines the material and service requirements across multiple contract periods, including a Base Year, four subsequent Option Years (Years 1 through 4), and a final 6-Month Option. For each contract period, the requirements are split into two primary Clinical Investigation Number (CLIN) categories: - **CLIN XX01 (Water Treatment Products):** Quantifies the required chemical products and delivery types for boiler and cooling systems. Key supplies include phosphate for scale control, sulfite for corrosion control, amine condensate treatments, caustic soda, passivating oxygen scavengers, and various liquid and tablet-based microbiocides/antimicrobials (including bromine, chlorine, and isothiazolin). Delivery formats specify container sizes such as 5-gallon, 15-gallon, and 55-gallon mini-bulk deliveries. - **CLIN XX02 (On-Site Water Treatment Support):** Sets a flat monthly requirement (12 months for full years, 6 months for the final option) for professional on-site support to monitor and maintain the water systems. The bidding sheet provides structured columns for unit issues, estimated quantities (which are halved for the 6-Month Option), unit pricing, and total pricing. This template is designed to allow vendors to submit comprehensive, year-over-year pricing for the full lifecycle of the water treatment contract.

This government document, Technical Exhibit (TE) 1, is a detailed inventory of mechanical utilities across three distinct geographic sectors or facilities: Main/Unlabeled Area, Down Range, and Edgewood. The exhibit categorizes and counts critical building systems—specifically Cooling Towers, Steam Boilers, Hot Loops, and Chilled Loops—associated with designated building numbers. The primary purpose of this exhibit within a federal solicitation or contract is to define the physical scope of work for maintenance, water treatment, or facility management services. It specifies the distribution of equipment, detailing multiple installations of steam boilers and loop systems across dozens of individual buildings (such as Buildings 4600, E1930, and E5126). This data allows contractors to accurately assess workload, equipment types, and resource requirements needed to service the listed heating, ventilation, and air conditioning (HVAC) and hydronic systems.

This document, titled "Technical Exhibit 2 – Estimated Product List," outlines the 2024 estimated product requirements for water treatment chemicals at the Aberdeen facility. It serves as a reference list for government procurement, detailing specific chemical formulations, packaging sizes, and estimated quantities needed for facility maintenance. The list is divided into two primary categories of water treatment products: - **Boiler System Treatments:** Includes sulfite for corrosion control, amine condensate treatment, multi-functional low-pressure formulations, polymer scale inhibitors, nitrite-based closed loop inhibitors, and oxygen scavengers for boiler layups. - **Cooling System Treatments:** Includes open circulating system scale and corrosion inhibitors, liquid stabilized bromine antimicrobials, and glycol-compatible closed-loop nitrite inhibitors. Product delivery methods and packaging units of issue vary based on operational needs, ranging from 5-gallon pails and 15-gallon carboys to 55-gallon mini-bulk deliveries. This exhibit provides potential contractors with the necessary quantity and packaging specifications required to bid on and fulfill the facility's water treatment supply contract.
