AMENDMENT TO REQUEST FOR PROPOSALS

Steam Turbine Generator

REQUEST FOR PROPOSALS #14P0012MG AMENDMENT NO. 3 Procurement Officer: Michael Grahek Effective Date: June 30, 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:

CHANGE: Due to the extension of the Submittal Deadline, the Deadline for Submittal of Questions is hereby changed FROM: June 20, 2014, 5:00pm AKDT

TO: July 7, 2014, 5:00pm AKDT

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

A3-Q1) The RFQ page No.37, there is a request to submit an alternate price based on maximum electrical output. LP extraction flow is not indicated. Could you please advise the LP extraction in this instance.

A3-A1) The intent of these requirements is to define an operating case with the highest possible electrical generation WITHOUT exceeding the maximum exhaust energy of the base design (estimated to be approximately 122 MMBTU/hr). The maximum exhaust flow for the base design is determined by CASE 11. (See Attachment 1 - revised Specification Section 00 43 33) This case represents a scenario of minimum extraction while generating 100% of the rated electrical capacity of the unit. In other words, UAF may wish to maximize the potential for electrical generation without investing additional capital dollars for condensing beyond what is required by the base design.

Based on the clarification above and the requirements provided in the RFP, the turbine mass balance for this case is as indicated on the Rate Response Form and as below:

Throttle flow: 280 kpph – fixed Exhaust flow: defined by exhaust energy @ 2 in Hg. Backpressure in CASE 11 - fixed MP extraction – 16 kpph – fixed LP extraction flow – varied as necessary to satisfy the turbine mass and energy balance

University of Alaska Fairbanks

RFP No. 14P0012MG - Amendment No. 3

Note that 3 of the 4 flows in the turbine are fixed per the requirements above, Offerors must therefore vary the LP extraction flow to maximize the electrical output of the generator and satisfy the mass and energy balance of the unit.

The Rate Response Form (RFP pp. 34-37) is hereby revised to reflect the correct "maximum extraction case." It now references CASE 11 . (See Attachment 2)

A3-Q2) Regarding Annex A, (Section 00 43 33 page 1) of the Technical Specification, the IP extraction flow for Design case-3, 6 and 7 is too small for viable extraction. The extraction non-return valve cannot accept the small flow which is less than 15% flow of maximum extraction flow (53 x 0.15 = 7.95kpph). During such low flow, the non-return valve may begin to chatter. Therefore, OFFEROR will consider these extraction will be zero flow.

A3-A2) These conditions are based upon lower extraction flows for campus distribution and main plant loads. These flow conditions shall be met and shall NOT be considered zero. It is the Offeror's responsibility to determine how best to meet them.

Per the instructions provided in Section 01 10 00, Paragraph 1.01 , it is not the intent of UAF to strictly specify the design of the unit. Offerors are free, and encouraged, to provide a design which best meets the functional intent of the specifications. Deviations from the specifications which an Offeror may deem necessary shall be clearly identified on the Statement of Compliance Form (Exceptions and Clarifications). Offerors must provide their reasoning for such deviations in adequate detail so UAF may consider the changes in its evaluation of proposals.

A3-Q3) It seems that we are having trouble converting the heat rates provided for the 2 extraction ports in the latest amendment that was issued on 6/24. To properly design the turbine, we would need flows in terms of lb/hr. When our engineer tries to convert the btu/sec into lb/hr, he is calculating flows that are more than the inlet throttle flow.

Can you either provide us the extraction flows required, like the original RFQ, or provide the method of calculation?

A3-A3) The extraction flow rates have been reintroduced into Section 00 43 33. Offeror shall note that the guarantees shall be based upon the extraction energy and NOT the flow rates. Given this, Offerors will not be required to strictly adhere to the flow rates indicated in the performance table. Changes are highlighted in the revised Section 00 43 33. (See Attachment 1)

CLARIFICATIONS:

A3-C1) Offeror shall provide a comprehensive technical discussion highlighting the advantages of its design, a detailed description of the equipment being offered, technical reasons for deviation from specification, control philosophy, and features which may distinguish its product from industry standard.

ATTACHMENTS: The following Attachments are provided and incorporated into the RFP:

• Attachment 1 -Revised Technical Specifications (00 43 33- Datasheets)

• Attachment 2- Revised Rate Response Form

All other terms and conditions remain the same.

Sincerely,

UNIVERSITY OF ALASKA FAIRBANKS
