The evaluation factors that will be used include:

Factor 1 – Schedule of Work

For the purpose of this evaluation factor, the contractor shall provide 2 separate but coordinated schedules. The first schedule shall cover the design and manufacturing of the stator core and armature winding; field winding refurbishment; and the design and supply of generator air coolers and work platform, including delivery to site. The second schedule shall cover the on-site work for the installation of the stator core and armature winding, associated field winding removal and reinstall, and all testing

The contractor shall presume the following:

• The Government will award separate, discrete delivery/task orders for the design and manufacturing of the equipment and installation of the equipment in a manner that will allow the contractor to perform on-site work with minimal to zero-time impact between manufacturing and installation activities.

• The Government will require that the on-site work for the installation of the new generator core and armature windings and the rotor pole refurbishment be completed within a maximum 100 calendar day window, commencing with the turn-over of the clean generator frame by the

Government.

• The Government will perform the following activities (with associated durations); Unit disassembly, armature winding and stator core removal (9 weeks), Unit reassembly (45 days), and Commissioning (30 days).

Offerors shall provide coordinated design and manufacturing, and installation schedules which:

a. Covers major items of both off-site and on-site work for both design through delivery and the installation and testing with milestone dates within the allowable time limits, and clearly define the critical path.

b. Includes blocks of time for, manufacture and transportation of materials, installation and testing work including unit balancing.

c. Include blocks of time for Government work and other Government contractors work, as identified above, including unit disassembly, armature winding and stator core removal , unit reassembly, and commissioning.

d. Shows the completion dates, logical relationships between activities (predecessors and successors), parallel relationships for concurrent activities.

e. Schedule must identify all necessary design approval RSNs as identified in specification section 013300A – Submittal Table, including the time allowed for Government review and response including necessary resubmittal for unapproved submittals.

The submitted schedule will be evaluated on compliance with the stipulated outage and completion windows, realism of scheduled manufacturing and installation activities and logical relationships. The

Government would like to minimize the outage durations on a per-unit basis as much as practicable for this 3-unit rewind. Although specification section 011410 – Use of Site identifies the work schedule as being Monday - Friday 7:00 AM to 5:00 PM, contractors are encouraged to look for options for staffing this work in a manner to reduce or shorten schedules for each unit (i.e. double shifts or 6-day work weeks). An offeror that can show a shorter, yet reasonable schedule based on the information required as above will receive a more favorable rating.

Factor 2 – Equipment and Installation Plan

Subfactor 2A – Equipment – Offerors shall provide mechanical and electrical design considerations, construction, installation, and proposed testing methods and procedures for the following major components:

a. Generator armature windings

b. Generator core.

c. Reinsulated field windings.

d. Air Coolers.

The product literature or narrative descriptions (i.e. cut sheets, brochures, drawings, etc.) will be evaluated to determine compliance with the specification requirements and innovation in design and manufacturing. Above this the narrative description the generator core and armature winding must minimally address the factors shown below:

Generator Core:

• Pole face losses

• Rotor vibration

• Unbalanced magnetic pull

• Magnetic Stability

• Modes of vibration in the core through 1200Hz and comparison tot that against slot passing frequency and air gap harmonic waveform and magnitude

Generator Armature Winding:

1. Parallel paths

2. Flux density distribution in gap, tooth, and core in units of (klines/in2)

3. Coil pitch and number of stator slots containing coil sides of the same phase

In addition, the Government will evaluate the offerors proposed warranted characteristics (losses) as a part of equipment subfactor. The offeror shall provide documentation detailing their equipment efficiencies and their anticipated warranted characteristics in Continuation of Section B – Supplies and

Services and Prices. The Government will directly compare guaranteed losses between manufactures.

An offeror with the lowest loss ratings will receive a higher technical rating.

Subfactor 2B – Installation plan and procedures - Offerors shall provide a narrative discussion of their planned installation procedures for the equipment that is listed in 2A above. The plan shall address refurbishing existing equipment and installation of new equipment. The offeror’s proposed plan and procedures will be evaluated for compliance with specification requirements, reasonableness with regard to schedule, methods of work, and other factors affecting their planned construction sequence.

Proposals which include a higher level of detail, including technical methods and processes, thereby reducing performance risk, will result in a more favorable technical rating.

Factor 3 – Company Experience
