AMENDMENT TO REQUEST FOR PROPOSALS

Steam Turbine Generator

REQUEST FOR PROPOSALS #14P0012MG AMENDMENT NO. 2 Procurement Officer: Michael Grahek Effective Date: June 24, 2014 Issue Date: June 4, 2014 ISSUED TO: ISSUED BY: All Prospective Offerors University of Alaska Fairbanks Procurement & Contract Services PO Box 757940 Fairbanks AK 99775-7940

Dear Vendor:

The following clarifications, revisions, and changes have been made to Request for Proposals No. 14P0012MG for a Steam Turbine Generator:

QUESTIONS: The following questions were received from potential Offerors. They are presented in a Question and Answer format.

A2-Q1) For the Guarantee Case, as defined on pages 1 and 2, of Section 00 43 33, what is the efficiency evaluation basis?

A2-A1) The steam turbine heat rate values provided by Offerors in Section 00 43 33 will be used as the basis for the efficiency evaluation. Section V. (Proposal Evaluation and Award) of the RFP has been revised accordingly. (See Attachment 2 – Revised Proposal Evaluation and Award)

A2-Q2) Should (we) use $3,520/KW at generator terminals and $11,864/BTU/kw-Hr, (which are the Liquidated Damages specified on page 82 of the Request for Proposal)?

A2-A2) The generator performance will be measured at the generator terminals. Furthermore, the Heat Rate LD value has been adjusted to reflect the capacity required of the unit over the life of the facility. The revised value is $7,027 /BTU/kW-Hr. The Gross Output for the KW LD value has not changed. The LD values are NOT utilized in the efficiency evaluation.

CLARIFICATIONS:

A2-C1) The required extraction output has been changed from a basis of pressure and flow to a basis of pressure and enthalpy. This will provide a common basis for evaluation that accounts for potential differences in extraction temperatures between the Offerors’ varying designs. Section 00 43 33 has been updated and changes have been highlighted. (See Attachment 1)

A2-C2) The guarantee case has been modified to better represent an average operating point over the life of the equipment. Section 00 43 33 has been updated and changes have been highlighted. (See Attachment 1)

PROCUREMENT & CONTRACT SERVICES Request for Proposals No. 14P0012MG – Amendment No. 2

V. Proposal Evaluation and Award

UAF will award a contract to the responsive, responsible Offeror whose proposal, conforming to the RFP requirements, receives the greatest number of evaluation points, price and other factors considered. This methodology permits award of a contract to an Offeror whose proposal does not offer the lowest price. Conversely, this methodology also permits award of a contract to an Offeror whose proposal does not receive the highest technical score.

A. Preliminary Administrative Evaluation

Prior to review by the RFP evaluation committee, all proposals will be evaluated to determine if they are responsive to the administrative and submittal requirements as to form, format, and substance. This administrative evaluation, performed by the responsible Procurement Officer, will determine that:

1. The proposal was received prior to the deadline.

2. The proposal was submitted in the correct format.

3. The correct number of copies of the proposal were submitted (one signed original and three complete copies), along with one complete electronic file containing the technical proposal and ALL Required Forms, and a separate sealed envelope containing the Rate Response Form.

4. Proposal forms were properly completed, signed and dated.

5. Any other necessary forms are included. 6. All material alterations or erasures to any forms, if any, were initialed by the signer of the

proposal, and noted on the RFP Statement of Compliance Form.

7. The proposal includes evidence of a current State of Alaska business license which is required by State of Alaska Statute at the proposal submittal deadline in order for Alaska preferences to be applied, if applicable.

Proposals failing to comply with all administrative requirements may be declared non-responsive and removed from further consideration.

B. Technical Evaluation

Proposals which comply with the preliminary administrative requirements of this RFP will be forwarded to an evaluation committee made up of University employees, and others as may be described herein, to score proposals for technical merit according to the criteria included herein (see below). The committee will serve under the guidance of the Procurement Officer, who serves as chair and ex officio member of the committee, and will consist of at least three qualified evaluators to perform the technical evaluation. The Procurement Officer will perform the price evaluation.

RFP No. 14P0012MG – Steam Turbine Generator Page | 26

University of Alaska Fairbanks RFP No. 14P0012MG - Amendment No. 2Attachment 2 - Revised Proposal Evaluation

and Award


Proposals will be evaluated and scored using a weighted method as follows:

Criteria Table

Past Performance/Experience 10%

Demonstrated ability to meet schedules and performance guarantees for steam turbines in the 10-30MW range. Demonstrated cooperative relations with Buyers. Information will be obtained from submitted references.

Service Capability 10%

Evaluations will be based on the capability of the manufacturer’s service organization to provide trained personnel to the UAF site for service. Factors that will be considered are proximity to Fairbanks, AK and demonstrated ability to supply service when requested.

Schedule 5%

Proposed schedule meets RFP requirements. The schedule will be evaluated based on whether the submitted schedule meets the requirements or presents advantages or disadvantages to the overall project.

STG Efficiency/Performance 15%

Efficiency/Performance will be evaluated based on heat rate (btu/Kwh) for all load cases. The Guarantee Load Case will be given more weight in the evaluation as this is a load case that is representative of where the turbine will be operated during the facilities life cycle. The assignment of points for this evaluation will be comparative with other vendors, not against a standard.

Product Quality 20%

Compliance with the technical specifications outlined herein. Identified deviations to the specification will be evaluated for an increase in quality, equivalent quality, or a decrease in quality. If compliance with the specification deviates significantly so that the equipment cannot function intended, the proposal may be considered non-responsive. UAF will evaluate the quality of the product (equipment and services) in the Offeror’s Technical Proposal based on the following criteria:

• Reliability and length between major overhaul • Ease of Maintenance • Controls and ease of integration with Owner’s DCS system • Compliance with performance requirements • Quality of auxiliary equipment • Compliance with specifications and Scope of Supply

Efficiency (i.e., lowest heat rate as defined in specification)

Price 40%

Prices will be evaluated in accordance with the methodology outline in Paragraph C below.

TOTAL 100%



and Award


Non-price, technical evaluations of each proposal will be performed independently by each individual committee member, with no attempt to reach a scoring consensus. The committee may discuss the details and features contained in proposals for the purpose of ensuring there is agreement about what is contained there and/or to clarify parts of an offer which may be unclear. The committee may use technical evaluation reports prepared by the Engineer and UAF staff.

For this solicitation the technical evaluation shall consist of evaluating the Offeror’s descriptive literature to ensure that the products offered provide the salient characteristics sought herein.

For the purposes of this RFP, the highest number of points attainable is 1,000, weighted 40% (400 points) for price and 60% (600 points) for technical, or non-price factors. If a proposal fails to earn an average non-price technical score of 360 points, the proposal may be found non-responsive and removed from further consideration for award. Additionally, proposals deemed outside the competitive range, either technically or for price, may be removed from further consideration.

C. Scoring Methodology

Non-Price: Proposals will be evaluated on non-price criteria as follows. Each member of the Committee will independently enter a scaled rating of 1 to 10 with 10 being the highest for each criterion outlined above. The scaled rating will then be multiplied by the weight to produce a weighted score for each factor. For example, if an evaluator assigned a scaled rating of 10 for Product Quality above, it would result in a raw weighted score of 200 (10 points X 20 [weight] =200). The weighted scores of all non-price factors will then be summed to provide a total weighted technical score for each proposal from each evaluator. The aggregate score of each proposal will then be divided by the number of evaluators to produce an average non-price technical score for each proposal. The highest number of technical points attainable is 600. If a proposal fails to earn an average non-price technical score of 360 points, the proposal may be found non-responsive and removed from further consideration for award. Upon completion of the non-price evaluation, discussions, requests for clarifications, or negotiations (without divulging competitors’ pricing, or standing) may be conducted with all qualified Offerors, or those Offerors who fall into a clear competitive range. Based upon the results of the scoring, UAF may seek clarifications from all Offerors in the competitive range. The competitive range shall include all proposals receiving both a minimum score of 360 points in the technical evaluation AND, in sole discretion of the procurement officer, achieving a technical score high enough to remain under consideration for award when ranked with other proposals received. This is not a strict mathematical formula and may not be challenged on that basis except in the case of obvious arithmetic errors.

Price: Price shall not be disclosed to the members of the evaluation committee until the technical evaluation process is completed. Points for price will be calculated by the Procurement Officer, based upon the pricing information submitted by each Offeror on the Rate Response Form and the application of Price Adjusters as outlined in the Criteria Table above.

Once the Price Adjusters are applied to the Offeror’s Lump Sum Price to determine the Adjusted Lump Sum Price, the Procurement Officer shall award points for price as follows:

• The Alaska Bidders’ Preference shall be applied, where applicable (note that UA Procurement Policy requires that, for RFP evaluation, preferences be applied to price only.)



and Award


• The maximum number of points allowable for price shall be given to the responsive,

responsible proposal with the lowest reasonable price. (For purposes of this RFP, this number is 400, 10 points X 40 [weight])

• Price points for the remaining responsive, responsible proposals shall be calculated as follows: (a) Multiply the lowest priced proposal price by the assigned weight for price. Divide that

number by the price of each higher priced proposal. This produces a mathematically proportional assignment of price points. See the example below:

(1) Offer A is $35,000, Offer B is $45,000, Offer C is $50,000. Therefore, (2) Assume Price is given a weight of 40. Offer A receives 400 points. (3) Offer B’s price points are calculated as follows:

$35,000 x 400 = 311 (rnd) Price points for B $45,000

(4) Offer C’s price points are calculated as follows: $35,000 x 400 = 280 Price points for C $50,000

(b) If additional rounds of price competition are required, the steps above are repeated for each subsequent price submittal.

D. Best and Final Offer

The Procurement Officer will ensure that the opportunity to clarify, confirm, or otherwise respond to questions is provided to all Offerors under consideration for award. This process will be sufficiently formal to ensure equity among Offerors, and will be fully documented. If, during discussions, there is a need for any substantial clarification of, or change in the RFP, an amendment will be sent to all interested parties. Requests for substantial clarification, and/or any amendments are valid only if issued in writing by the responsible Procurement Officer.

General questions may be directed to all Offerors. However, questions which pertain only to a particular proposal shall be sent only to that Offeror. Offerors who fail to respond with the required information by the deadline stipulated, or who fail to adequately support apparent discrepancies, imbalances, or disproportionate submittals, may be declared non-responsible.

Upon receipt of clarifications, the Evaluation Committee may adjust each Offeror’s score, if necessary, to reflect any new information. Should it be necessary, as a result of additional information obtained during this clarification process, to amend the RFP, a written amendment may be issued.

UAF reserves the right to request clarifications and request a best and final offer (BAFO) from each Offeror within the competitive range. However, UAF also reserves the right to make award of a contract based exclusively on the submitted proposals without seeking a BAFO.
