Justification and Approval (J&A) for Other Than Full and Open Competition

This document justifies the use of other than full and open competition for the procurement of a Cooling Tower (Baltimore Aircoil Company) as a Firm Fixed Priced Task Order from Pittsburgh MATOC Contracts. The action is being processed to address the needs of the Central Utility Plant and the facility's chilled water system.

• Procurement of a Baltimore Aircoil Company cooling tower.

• The cooling tower is essential for the facility's major, highly specialized chilled water system, which includes chillers, mechanical and piping components, electrical infrastructure, and distribution piping.

• Statutory Authority: Cites 41 USC §3304(a)(1) - Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements.

• Nature of Action: Changing manufacturers would increase cooling system downtime, causing unacceptable delays in patient care. Utilizing the existing Baltimore Aircoil Company cooling tower preserves investment in spare parts and maintenance personnel training. Cooling towers and chillers are not plug-and-play and require matching existing systems to function efficiently.

• Unique Qualifications/Acquisition Nature: The system requires specific components (Baltimore Aircoil Company cooling tower and potentially Trane chillers) that are not interchangeable without significant cost and complexity. Market research indicated that other manufacturers' products, or products lacking specific features, do not meet or cannot be modified to meet the agency's needs without extensive reconfiguration.

• Cost Impact: Using a non-specified cooling tower would result in a large increase in costs due to necessary reconfiguration of the piping system, alterations to the electrical system, and reconstruction of the floor. Replacing existing viable Trane chillers would also significantly increase project costs.

• Market Research: Manufacturer literature was examined, and while operational similarities exist, piping, electrical, and size/weight configurations are unique to each manufacturer. The designer of record investigated other chillers, finding the additional cost outweighed benefits and would result in a more complex and less reliable system.

• Contract Type: Firm Fixed Priced Task Order.

• Contracting Activity: Department of Veterans Affairs, VISN4, NCO4, Construction West, VAPHS University Drive Medical Center, Pittsburgh PA 15240.

This document is a justification for sole-source procurement and does not contain submission or evaluation criteria for proposals.

Justification and Approval (J&A) for Other Than Full and Open Competition

This document justifies the use of other than full and open competition for the procurement of a Cooling Tower (Baltimore Aircoil Company) as a Firm Fixed Priced Task Order from Pittsburgh MATOC Contracts. The procurement is necessary to maintain the Central Utility Plant's chilled water system, which is critical for patient care at the hospital.

• Procurement of a Baltimore Aircoil Company cooling tower.

• The cooling tower must be compatible with the existing chilled water system, including chillers, mechanical and piping components, electrical infrastructure, and distribution piping.

• Sole Responsible Source: The Baltimore Aircoil Company cooling tower is required because changing manufacturers would lead to unacceptable downtime and delays in patient care. Existing chillers are compatible with this brand, and replacement of existing chillers would significantly increase costs.

• Unique Qualifications/Nature of Acquisition: The system's components (piping, electrical, size/weight configurations) are unique to the manufacturer, making direct replacement or modification of other brands impractical and costly.

• Market Research: Market research indicated that while some similarities exist between manufacturers, the specific configurations required for this system are unique. Using a non-Baltimore Aircoil cooling tower would necessitate extensive and costly reconfiguration of the piping, electrical systems, and floor structure.

• Cost: Utilizing the existing Baltimore Aircoil Company cooling tower avoids substantial duplication of costs associated with spare parts, training, and system reconfiguration.

• Contract Type: Firm Fixed Priced Task Order.

• Procurement Method: Other Than Full and Open Competition.

This document is a justification for a sole-source procurement and does not contain submission or evaluation criteria for proposals.

Not applicable, as this is a justification for other than full and open competition.

• The acquisition plan action ID is 36C244-26-AP-0073.

Justification and Approval (J&A) for Other Than Full and Open Competition

This document justifies the Department of Veterans Affairs' intent to procure a Trane Centrifugal Chiller and associated Baltimore Aircoil Company cooling tower on a brand-name basis, utilizing other than full and open competition. The procurement is for the VAPHS UD Chiller Plant to match and integrate with the existing 3 chillers.

• A Trane Centrifugal Chiller.

• A Baltimore Aircoil Company cooling tower.

• The items are to be procured using a Firm Fixed Priced Task order from Pittsburgh MATOC Contracts.

• Only One Responsible Source: The existing system is designed for Trane chillers. Utilizing a different brand would require significant reconfiguration of piping, electrical systems, and floor space, leading to substantial cost increases and potential system downtime. The current chillers are viable and will remain so for the foreseeable future.

• Unique Qualifications: Trane chillers and associated cooling towers are already in use, and the existing chillers are compatible. Replacing them would be exponentially more expensive.

• Market Research: While other manufacturers (York, Carrier) were considered, their products would require extensive modifications to integrate, increasing costs and complexity.

• Cost: The anticipated cost is determined to be fair and reasonable, with the brand-name specification avoiding duplication of costs for spare parts and maintenance training.

• The procurement is an RFP (Request for Proposal).

• The contract award will be a Firm Fixed Price.

• Evaluation criteria will be based on all source selection criteria in the solicitation.

• The Source Selection Authority's decision will be based on business judgments and trade-offs.

• The document mentions that the Prime Contractor responsible for acquiring the unit will be an SDVOSB (Service-Disabled Veteran-Owned Small Business), and there are numerous Trane distributors with SDVOSB affiliations.
