Statement of Work

Medical-Grade Liquid Bulk Oxygen

The Contractor shall provide Medical-Grade Liquid Bulk Oxygen to:

Veteran Affairs Medical Center (VAMC) Providence

Building 1

830 Chalkstone Avenue

Providence, RI 02908-4734

Period of Performance

The period of performance is one-year base period plus four one-year option periods.

1. General

1.1 The purpose of this requirement is to establish a committed source of supply of medical-grade liquid bulk oxygen for this facility. This Government facility does not own its own bulk oxygen tank. The current contractor has provided a contractor-owned 3000-gallon tank with an appropriate 400-gallon reserve tank back-up system meeting NFPA 99 code standards. If warranted, the new contractor shall provide a new contractor-owned tank and reserve tank with equal or greater capacities. New tank and reserve tank back-up system shall meet NFPA 99 code standards. If warranted, the new tank shall be located on Armed Forces Blvd on the existing gated concrete tank slab. The contract shall also provide for digital readouts of all tank parameters in two (2) separate and distinct locations within Building 1. Specifications for this facility are listed in the O2 Tank Pad As-Builts (Appendix A), Med Gas EOSC Final Report & Commissioning Report (Appendix B).

1.2 If warranted, the contractor shall coordinate removal of the existing tanks and back-up system with the existing contractor and submit a plan to provide uninterrupted service during the changeover. The contractor shall make all the necessary connections, tie-ins and adjustments to ensure that the newly installed tank is properly connected to the existing Medical Center distribution system utilizing the attached Bulk Oxygen Commissioning Report dated 26 March 2018 by Fitzemyer & Tocci Associates. Contractor is responsible for ensuring that the new tank is tied into the existing building distribution system without any interruption to service. The contractor shall coordinate the tie-in of the new system during the weekend hours so as not to impact clinical operations.

1.3 The contractor shall provide the total cost as well as the unit cost per Cubic Foot (CF) to supply 36,500 CCF of medical-grade, liquid oxygen which is the estimated approximate total annual requirement for the Providence VA Medical Center. There is no express or implied guarantee that these quantities will be purchased. Please note that the contract that includes the installation of contractor-owned equipment may include a 30 day transition period at the beginning and end of the contract period. (See paragraph 5.1). The contractor shall provide two (2) line item costs in submitting their bid; (1) total cost/unit cost for 36,500 CCF of medical-grade bulk oxygen (2) annual/mthly rental cost for the storage tank.

1.4 Prior to first filling, contractor must perform in service training to include the following facets for contractor owned and government owned systems: the refill procedure, any preventative maintenance support requirements that may be needed from the Medical Center systems, and an explanation of all the volume alarms and low pressure set-points. The contractor will provide written procedures and training for VA staff for protocols to accomplish emergency shutdowns or other sudden, unplanned termination of the refilling process. Contractor will provide 24/7 emergency contact name(s) and telephone number(s).

1.5 Prior to first filling, and annually thereafter, alarm set point testing and written verification must be presented through the use of a qualified third party expert per NFPA 99, latest Edition for contractor owned and government owned systems. Any code deficiencies in the Medical Center s existing system, as defined by NFPA 50, 1.3.3, Bulk Oxygen System , must be identified by the contractor. A detailed explanation of these deficiencies must be present in writing to the COR. Receipt of this written explanation must be signed by the COR.

1.6 Prior to the first filling, and as part of the contractor s regular maintenance and inspection plan, the contractor must verify in writing the accuracy of all gauges on contractor owned tasks. If the gauge(s) are government owned, contractor will provide, if requested after award, a written proposal with price to verify accuracy of the gauges(s). This facility may choose to exercise this option at its desire.

U.S.P. 23

Density data and volume measurement equivalents published in Compressed Gas Association Pamphlet No. P-6, titled Standard Density Data, Atmospheric Gases and Hydrogen shall be used when necessary to convert measurement of gases from one form to another. For example, the following conversion factor shall apply for conversion from gallons to cubic feet.

Calculation based on data in CGA P-6

1ft3 liquid O2 = 860.6 ft3 gas (Table 1)

1ft3 liquid O2 = 7.48052 gal (Table 2)

Therefore:

7.48052 gal (1ft3) liquid O2 = 860.6 ft3 gas

1 gal liquid O2 = 860.6 ft3 gas

7.48052

1 gal liquid O2 = 115.05 ft3 gas

Or more commonly quoted as 1 gal liquid O2 = 115.1 ft3 gas

9. Contractor Owned Cylinders

9.1 This section applies to all contractor owned cylinders that are provided under this contract as a back-up system to a primary bulk oxygen system.

9.4 All unauthorized or inapplicable markings, tags, and labels shall be removed. When shipment is by commercial carrier, shipping tags complying with Federal Standard 123F dated 5/15/91 shall be attached to each cylinder so as to be protected by the valve protection cap. The contract data marking required by the applicable standard shall be applied to one side of the tag and the identification markings on the reverse side. Consignee markings may be omitted when shipment is by contractor s truck.

The following factors shall be used to evaluate quotations:

Technical or Quality

Past Performance

Price

Evaluation Approach. The Government will evaluate quotations using the comparative evaluation process outlined in, where quotations will be compared to one another to determine which provides the best benefit to the Government. The Government reserves the right to consider a quotation other than the lowest price that provides additional benefit(s). Quotations may exceed minimum requirements of the solicitation. The Government reserves the right to select a quotation that provides benefit to the Government that exceeds the minimum requirements of the solicitation but is not required to do so. Each response must meet the minimum requirements of the solicitation. The Government is not requesting or accepting alternate quotations. The evaluation will consider the following:

Technical or Quality: The quotation will be evaluated to the extent to which it can meet and/or exceed the Government s requirements as outlined in the solicitation and based on the information requested in the instructions to quoters section of the solicitation.

Past Performance: The past performance evaluation will assess the relative risks associated with a quoter s likelihood of success in fulfilling the solicitation s requirements as indicated by the quoter s record of past performance. The past performance evaluation may be based on the contracting officer s knowledge of and previous experience with the supply or service being acquired; Customer surveys, and past performance questionnaire replies; Contractor Performance Assessment Reporting System (CPARS) at http://www.cpars.gov/; or any other reasonable basis.

Price: The Government will evaluate the price by adding the total of all line-item prices, including all options. The Total Evaluated Price will be that sum.

Options. The Government will evaluate quotations for award purposes by adding the total price for all options to the total price for the basic requirement. This includes options under FAR 52.217-8, Option to Extend Services, which applies to this solicitation. Evaluation of options under FAR 52.217-8 will be accomplished by adding six months of the quoter's price for the last potential period of performance under this contract to the quoter's total price. For example, if the contract includes option periods that are exercisable under FAR 52.217-9, the quoter's total price for the purpose of evaluation will include the base period, all option periods, and an additional six months of the last option period. Quoters must price only the base and option periods specified in the contract line item numbers (CLINs), and shall not submit a price for the potential six-month extension of services under FAR 52.217-8. The Government reserves the right to exercise the option under FAR 52.217-8 before the end of any of the contractor's performance periods and will be exercised at the price and/or rates in effect at the time the clause is exercised. Evaluation of options shall not obligate the Government to exercise the option(s).
