1. Contracting Activity.

Naval Facilities Engineering Systems Command, Hawaii (NAVFAC HI), Architect-Engineer Contract Division, Joint Base Pearl Harbor Hickam (JBPHH).

2. Description of the Action Being Approved.

Request approval for use of Atlas Copco ZR 900 VSD Low Pressure Air Compressor (LPAC), Atlas Copco ND2500 VSD/Water Cooled Adsorption Dryer, and Atlas Copco Optimizer 4.0 Central Controller for Work Order Number 1547565, RM15-1622 Replace Station K10 and Modify Building 641 Electric Service, JBPHH, Honolulu, Hawaii.

3. Description of Supplies/Services.

The scope of work is to replace the existing low pressure air (LPA) system and high pressure air (HPA) system at Building 641 (B641). This includes the LPACs, HPACS, air dryers, cooling towers, pumps, heat exchangers, piping, transformers, switchgear, motor control center, and system controls. This project requires integrating the new equipment and controllers into the existing supervisory control and data acquisition (SCADA) system, which connects to Building 149 (B149).

SCADA will also be monitoring the existing emergency power Generator and new Automatic Transfer Switch operational status. The Atlas Copco Optimizer will be the central controller used for all Atlas Copco equipment. Per Unified Facilities Criteria (UFC) requirements, B641 requires 125 PSI at the outlets, which requires the plant to be set at 150 PSI. The UFC also requires the LPA system to be Grade “D” Breathing Air, which requires ISO 8573-1 Class-0 or “oil-free” construction.

The LPA system at B641 operates as the secondary plant for Shipyard & IMF, with B149 as the primary.

The existing systems will be replaced with one Atlas Copco ZR 900 VSD. The Atlas Copco LPAC is the largest capacity, oil-free, VFD-driven, 460V powered, rotary screw compressor, rated at 4,000 SCFM at 150 PSI. The Atlas Copco ZR 900 VSD is packaged together with the ND 2500 VSD/Water Cooled Adsorption Dryer. The Atlas Copco Optimizer 4.0 Central Controller is used to automatically synchronize and control the LPAC and integrated rotary drum dryer with a defined set-point.

The total estimated value for the use of the Atlas Copco equipment and controls is . The breakdown is as follows:

4. Statutory Authority Permitting Other Than Full and Open Competition.

This request is submitted pursuant to the authority of FAR 6.302-1 and Title 10 U.S.C. 2304(c)(1), only one responsible source and no other supplies or services will satisfy agency requirements.

5. Rationale Justifying Use of Cited Statutory Authority.

The Atlas Copco ZR 900 VSD is the only rotary screw compressor currently available in the market that efficiently exceeds the historic LPA demand, and meets UFC 4-150-02, relative to Grade-D Breathing Air requirements. The Atlas Copco ZR 900 VSD compressor is unique because it is packaged with the Atlas Copco ND2500 VSD/Water Cooled Adsorption Dryer. The compressor and dryer are controlled as a single unit. The Atlas Copco Optimizer 4.0 Central Controller contains propriety software to interface with the compressors and dryers.

NAVFAC HI seeks to replace the LPA system at B641 with Atlas Copco brand name compressor and associated equipment for the following reasons:

a. Meets UFC and Mission Requirements: The scope of this project was driven by the historical average continuous LPA system demand. The current operations do not meet the UFC required flow demand with 125 PSI at the outlets, which require the plants to be set at 150 PSI. In order to meet UFC requirements under UFC Sections 4-150-02 and 3-420-02FA, various options on the type and quantity of compressor and air dryers were evaluated, as well as the efficiency of the equipment. The various options included using only centrifugal base-load compressors; using only VFD-driven screw compressors; or using a combination of centrifugal base-loaded compressors and VFD-driven screw compressors. The design requirement determined to be the best option for this project in terms of operating most efficiently and streamlining equipment maintenance, operator training, and spare parts inventory is to utilize one oil free VSD rotary screw compressor that operates at 460V.

Centrifugal compressors rely on inlet vanes or inlet throttling valves that limit their overall range and efficiency of operation. Since the compressed air demand at the Shipyard is highly irregular and wide-ranging, two key components of compressor equipment selection are variable capacity control and flow at minimum-load conditions. Operating air compressors with high levels of inlet throttling and/or while unloaded is inefficient, and frequent start/stop cycles are detrimental to motors and mechanical components of the compressor. Controls must also operate flawlessly to prevent destructive surging of centrifugal compressors. The only equipment that meets all these criteria is the Atlas Copco ZR 900 VSD. The new

ATLAS Copco ZR 900 VSD compressor will exceed the actual capacity of the existing equipment by 60% at the UFC required 150 psi.

b. Reduces Operating Costs and Increases Functionality: Operating at 460V allows for a greater number of qualified NAVFAC HI personnel to maintain and repair the units, which contributes to lower installation and operating costs. The Atlas Copco Optimizer 4.0 Central Controller interfaces with all Atlas Copco compressors and dryers. This controller will interface with the Atlas Copco equipment in B149. B149 is connected to P-089 Satellite LPA Plant. By having all LPACs from B641, B149 and P-089 connected to the Optimizer 4.0 Central Controller, there is increased SCADA functionality which allows for standardization of hardware, software, and spare parts inventory. Functional readiness is also improved through greater efficiency in operating and maintenance personnel, in terms of streamlined operations, standardized maintenance, simplified troubleshooting, and common repair procedures.

As referenced in executed J&A No. 21-07, the Designer of Record (DOR) for the B149 project, performed a cost analysis to determine the most effective combination of compressors to use in order to meet the required capacity and UFC regulations. Three scenarios were evaluated: 1) using all Atlas Copco compressors; 2) using a combination of 2 different brand controls; and 3) using a combination of 3 different brand controls. The analysis determined that using all compressors of the same brand is the most cost effective. As Atlas Copco compressors are installed in P-089 Satellite LPA Plant, the most cost effective option is to install Atlas Copco compressors in B149 and B641 as well.

c. Decreases Cybersecurity Vulnerabilities: Utilizing the compressed air controls environment provided by Atlas Copco reduces the number of hardware and software attack vectors to potentially gain entry to the SCADA system, which decreases the exposure to cyber threats.

6. Description of Efforts Made to Solicit Offers from as Many Offerors as Practicable

Executed J&A No. 21-07 issued a sources sought in beta.sam.gov, Contract Opportunities on 15 April, 2021. The sources sought requested that all interested parties respond within 15 days after date of publication of the synopsis. The sources sought requested interested parties to respond to the requirement to be considered if able to provide compatible products to the Atlas Copco ZR 900 VSD, Atlas Copco ND 2500 VSD/Water Cooled Adsorption Dryer, and the Atlas Copco Optimizer

4.0 Central Controller. By the due date, two responses were received; however, neither firm provided the requested information. Therefore, it was reasonably assumed that Atlas Copco is the only source that could satisfy agency requirements. NAVFAC HI considers the beta.sam.gov synopsis as its market survey. Other manufacturers that produce LPACs, each with their own unique proprietary systems, are Sullair, Ingersoll-Rand, Kaeser Compressors, and Hitachi.

However, the only manufacturer that meets the project specifications and design parameters is Atlas Copco.

As referenced in executed J&A No. 21-07, also performed its own market research and provided their findings on 08 October 2020 to the Government. The market research evaluated four compressor types (oil free VSD Screw 2-stage; oil free constant speed Screw; oil free centrifugal 3-stage; and oil free centrifugal) and the various models of the compressors manufactured by Atlas Copco, Sullair, Ingersoll-Rand, Kaeser Compressors, and

Hitachi. The results indicated that Atlas Copco was the only manufacturer to meet project specifications and design parameters.

7. Determination of Fair and Reasonable Cost.

The Contracting Officer has determined the anticipated cost to the Government of the supplies/services covered by this J&A will be fair and reasonable.

8. Actions taken to remove barriers to future competition.

NAVFAC HI will continue to monitor the LPAC industry to determine if another LPAC system becomes available, and if another potential source emerges, NAVFAC HI will assess whether competition for future requirements is feasible.
