E.2.1 Addendum Evaluation -Commercial Items

Basis for Award

The Government intends to award multiple firm-fixed price IDIQ contract resulting from this solicitation utilizing the Lowest Price Technically Acceptable (LPTA) source selection process as prescribed in FAR 15.101-2. Awards will be made on an LPTA basis to the responsible offeror that submits an offer meeting the solicitation requirements and is the lowest priced technically acceptable offer. The contract awards will be based upon the following evaluation factors:

Factor 1 Price

Subfactor A Lowest Price Acceptable

Subfactor B Past Performance

Factor 2 Technical Acceptability

Subfactor A Manufacturer/Distributor Business Documentation

Subfactor B Product Technical Literature and Warranty Information

Factor 3 Sample Product Demonstration

The Lowest Price proposals will be evaluated against stated factor criteria, and adjectively rated using Acceptable or Unacceptable. Awards will be made to the proposals that are Lowest Priced and Technically Acceptable.

The Government will review the offeror s Commercial Price List as part of the fair and reasonable determination of the proposed prices and will not receive an adjectival rating. We use this to verify the information you are submitting is accurate.

Only the lowest priced proposal will be submitted for Phase 2 Technical Acceptability evaluation.

The adjectives are clearly defined in the table provided below:

Adjective

Definition

Acceptable

All the minimum acceptable criteria are clearly set forth in the offeror s proposal(s). The offeror s proposal(s) meets the performance and technical acceptability requirements as set forth in the statement of work.

Unacceptable

Not all the minimum acceptable criteria are met by the proposal(s). The Offeror s proposal(s) contains one or more deficiencies. The proposal(s) fails to meet specified minimum performance and technical acceptability requirements set forth in the statement of work.

Note: If the offeror s response to one of the subfactor s in an factor evaluation as unacceptable, the OVERALL determination for that factor may still be acceptable. However, if any evaluation factor receives an unacceptable in the overall rating, the entire proposal becomes unacceptable.

The evaluation will be conducted in four Phases:

Phase 1 Factor 1 Price:

Proposals received in response to this solicitation, will have an initial screening process in which each offeror will be ranked from lowest to highest total evaluated price by each CLIN category from the grand total in the Attachment 1 ALD Pricing Schedule.

The Government will conduct evaluation price proposals by reviewing and validating the dollar amounts and calculation of each contract line item and the subsequent option periods Attachment 1 - ALD Price Schedule (Proposal Pricing Sheet), submitted by the Offerors. The Government will refer to the price of each CLIN/SLIN category which includes the total price for all five contract periods for each contract line item, resulting in the total evaluated price.

Contract Line Item Number Evaluation: evaluation of prices will be conducted on each CLIN separately. The proposed prices of offered brand/model/packages will be evaluated to determine whether the lowest proposed prices are fair and reasonable. Each assistive listening device model/package offered for a CLIN shall be separately priced for the base and all options to arrive at a total price for evaluation purposes. A total price for evaluation for each model/package offered for a CLIN is calculated by multiplying the unit price by the year estimated quantity and summing the total prices for the base year and all option periods, to determine the lowest evaluated price. The CO shall consider for up to 4 awards for brand/make/model per CLIN.

EXAMPLE: More than one award of various assistive listening devices brand/models/packages offered for a CLIN may be made. If more than one award is made for a CLIN the awarded offers will still be determined to be the lowest evaluated price and technically acceptable offers. For example, assume for CLIN 0001 that multiple offers of various brand/model/package assistive listening devices were received. If all offers are compliant with the solicitation (i.e. FAR 52.225-5 Trade Agreements and C.11. FAR 52.225-6 Trade Agreements Certificate regarding U.S.-made or designated country end products requirements), and are technically acceptable, but the Government decided it will make four awards, then it will look to the four lowest evaluated priced offers for CLIN 0001. The remainder proposals for CLIN 0001 would be unsuccessful due to price.

Note: The prices offered for any Schedule B.3 OPTIONAL SUB-LINE Accessories and/or parts (Attachment 2) offered will be excluded from the price evaluation for CLIN award purposes. The Base and all Options prices for the Schedule B.3 accessories and/or parts will be evaluated for price reasonableness IF an award for a corresponding assistive listening device brand/model/package offered for a CLIN, is made. The Government will award B.3 Optional Sub Line Accessories and/or parts if it is in the best interest to the government at time of award.

Proposals that fail to include a price for the base year and each of the four option years for line items may be rejected and receive no further consideration.

The Government shall evaluate the proposed price to determine whether it is fair and reasonable. The Government shall evaluate price reasonableness using price analysis techniques as prescribed in FAR 15.404-1(b)(2).

Unbalanced Pricing: Unbalanced pricing exists when despite an acceptable total evaluated price, one or more contract line items is significantly overstated or understated as indicated by price analysis techniques outlined in FAR 15.404-1. A proposal may be rejected if the Contracting Officer determines the lack of balance poses an unacceptable risk to the Government.

Subfactor A: Lowest Price Acceptable

If the lowest priced proposal is not determined to be Acceptable in both Phase 1 Factor 1 Price then the next lowest-priced proposal will be submitted for evaluation.

The lowest proposal will be submitted for technical evaluation under Phase 2 (technical acceptability). If the offeror s proposal passes phase 2 (technical acceptability), the proposal will enter phase 3 (product demonstration) for evaluation. If a proposal fails to pass any phase of the evaluation, it will be removed from consideration and the next lowest priced proposal will be submitted to be evaluated.

The lowest priced proposals that passes all phases of the evaluation, will receive the award.

Phase 2 Factor 2: Technical Acceptability Evaluation:

The Government shall perform a technical evaluation on the lowest priced offeror s prepared Technical Acceptable documents to determine whether the contractor s capabilities allow for the successful performance of this requirement. The Source Selection Evaluation Board (SSEB) will evaluate the lowest technically priced proposal against the Technical Acceptability and its subfactors as stated in the solicitation. This results in a determination of that the proposal are Acceptable or Unacceptable for Phase 2 of the evaluation. The proposal that passes Phase 2 with Acceptable rating then will advance to Phase 3 Product Demonstration.

Any proposal that fails to provide sufficient evidence of compliance to the statement of work and instruction to offerors will receive an Unacceptable rating and no further consideration for award.

If the proposal fails to provide sufficient evidence of compliance Factor 2- Technical Acceptability the proposal will receive an Unacceptable rating and no further consideration for award. The Source Selection Evaluation Board will then review the next Lowest Price Technically Acceptable proposal.

The following Subfactors will be evaluated: (Subfactors A through B are of equal importance)

Subfactor A: Manufacturer/Distributor Business Documentation

The government will review the Manufacturer/Distributor Business Documentation for each model offered to determine whether or not the business documentation meets or exceeds the minimum technical requirements as stated the solicitation.

An offer will be considered technically acceptable if it meets the following criteria:

If the offeror is a distributor, a letter of commitment will be evaluated to determine whether the offeror s source of supply is sufficient to satisfy the Government requirements for the duration of the contract period of performance to include base and option periods.

The letter shall:

Be on the manufacturer s own company letterhead.

Note the commitment by the product name, brand, product country of origin and information on shipment procedures.

Offerors will attest in writing whether or not their products being offered are in compliance with the TAA, Non-Manufacturer Rule, or BAA.

Identify the manufacturer s UEI, TIN, and FDA Registration for the current year (if FDA registration is applicable).

Identify the time frame of shipments to F.O.B destination upon from receipt of order from the government; and

State an overview of how the offeror s business relationship will work between manufacturer and distributor and include the offeror s shipment procedures

This evaluation will result in a determination that the business documentation is Acceptable or Unacceptable. All documentation that fails to provide sufficient evidence of compliance with the minimum technical requirements will receive Unacceptable and no further consideration.

Subfactor B Product Technical Literature and Warranty Information

The product technical literature and warranty information will be evaluated to determine whether the proposed items meet the MTRs in the solicitation. All documentation that fails to provide enough evidence of compliance with the minimum technical requirements will receive and unacceptable no further consideration. The Government will review Attachment 2 Detailed Product Information Form which will be submitted for all proposed items for accuracy and compliance to minimum technical requirements.

This evaluation will result in a determination that the business documentation is Acceptable or Unacceptable. All documentation that fails to provide sufficient evidence of compliance with the minimum technical requirements will receive Unacceptable and no further consideration.

The following subfactors will be evaluated as follows:

Descriptive Literature:

The Government will evaluate the offeror s product technical literature for each CLIN/SLIN proposed to evaluate if it meets the minimum technical requirements as stated in this solicitation in Section E.2.2.

For the purpose of determining technical acceptability, descriptive literature must identify the appropriate Make, Model, Type to clearly demonstrate the items meet the minimum technical requirements.

Note: Product notes in a catalog is not acceptable and will be considered unacceptable. Information that is not marked properly for offered CLIN(s)/SLIN(s) will be considered technically unacceptable.

Product Warranty:

The Government will review Attachment 2 Product Detail is where the contractor shall list the detail of their warranty information. The warranty will be reviewed in its entirety to determine the extent to which the provided warranty meets and/or exceeds the minimum requirement.

Subfactor C - Past Performance

The offeror shall submit a list of three (3) to five (5) references on projects covered in similar magnitude from within the last three years using, Attachment 8 Past Performance References as guidance. The past performance questionnaire is for the offerors to send to their current and or previous references with instructions to return to the completed questionnaire to the Government.

NOTE: IN THE CASE OF AN OFFEROR WITHOUT A RECORD OF RELEVANT PAST PERFORMANCE OR FOR WHOM INFORMATION ON PAST PERFORMANCE IS NOT AVAIALBLE, THE OFFEROR MAY NOT BE EVALUATED FAVORABLE OR UNFAVORABLE ON PAST PERFORMANCE (SEE FAR 15.305(A)(2)(iv) AND WILL RECEIVE NEUTRAL RATING. AS THIS REQUIREMENT IS LPTA A NEUTRAL RATING SHALL BE CONSIDERED ACCEPTABLE.

Phase 3 - Factor 3: Product Demonstration:
