Technical Approval: Date: 2026.06.04 14:13:58 -06'00' Date:

1. The person signing the specifications package as “Prepared by” shall have developed or assembled the written specifications.

2. The person signing the specifications package for “Technical Approval” shall have been in responsible charge of the overall design including developing or assembling the specifications. This person will typically be the design team leader. In cases where the designs described by the specifications meet the criteria for preparation by a registered engineer or architect, this person shall be registered with the applicable professional designation after their signature, such as P.E. for professional engineer or R.A. for registered architect. By this signature, this person is certifying the written specifications convey the design intent as portrayed on the drawings included therein. For specifications package containing designs from multiple disciplines, it is the signing individual’s responsibility to ensure (using procedures defined by his/her organization) that the technical information prepared by other professions and disciplines and depicted in the document is compatible with the overall design intent and that the documents used to depict that information (e.g., drawings) include signatures with appropriate professional registration designations.

3. Revisions to designs after drawings and written specifications are originally signed will be reviewed by a design team representative (typically the design team leader). The review of written specifications revisions must be documented on a signature sheet included with the revised written specifications (see below).

1.06 EXISTING CONDITIONS

A. There are four hydro-electric generating units in the HH Power Plant, called G1 through G4.

B. Turbine Runner:

1. Units G1 through G4 are equipped with 105,000 HP Francis-type turbine runners, designed and manufactured by Allis-Chalmers, Milwaukee, WI. The runner throat diameter is 126 inches.

2. Each runner contains 15 blades, also referred to as “buckets” or “vanes”.

3. The runners have been in service since 1950, and each runner has had cavitation damage repaired on multiple contracts. Each contract has had different work crews and time-limited scope of work resulting in different conditions for each runner.

4. Most of the runner is carbon steel, but a significant amount of stainless steel exists from previous repair areas:

a. Base metal of the runner assembly is cast steel conforming to Federal

Specifications QQ-S-681b, Class 2 Medium, Annealed. Copy of historical specification is made a part of Section L – Attachments.

5. Runner material will be tested in accordance with 05 50 00 – Metal Fabrications for each unit to verify material type for information.

6. Previously applied protective coatings on runners may contain regulated metals.

Other contaminants may be present.

7. On units G1 through G4, runner damage is mostly observed as cavitation-enhanced corrosion in the crown area and on the face of the blades. This corrosion has been characterized as severe surface pitting with a porous appearance reminiscent of some kinds of cheese. The leading edge of most of the blades exhibit corrosion erosion. Although these units are not known for having cracks in the blades, some cracks have been previously found. Several of the units have already been clad with stainless steel in the most troublesome areas.

48 13 13 - 4

8. On unit G1 a trailing edge extension was added to each of the 15 blades in a trial attempt to mitigate cavitation damage. See section 51 00 00 – Information Available to Bidders.

9. The work area of the turbine runner is accessible through two large doors in the draft tube:

a. Draft tube doors are accessed from Floor 1 at El. 3070.50.

b. Access opening dimensions:

1) Door opening dimensions are 23.5 inches wide by 29.5 inches high.

2) After installation of the draft tube work platform, the access opening dimensions are 23.5 inches wide by 20 inches high.

10. Main access to the power plant is from ground level Floor 4 at El. 3113.50.

1.07 AMBIENT CONDITIONS

A. Each of the subject units consisting of the generator and turbine is entirely indoors, where the ambient temperature ranges from 60 degrees Fahrenheit to 80 degrees Fahrenheit.

1.08 COORDINATION

A. Coordinate with COR to finalize scope of repairs based on Government’s initial assessment and Contractor’s secondary assessments.

1.09 SEQUENCING

A. Work will follow the following sequence:

1. Government physically marks zones to receive repairs, and issues initial assessment form designating zones requiring repair, including:

a. High and Low priority designations.

b. Defect Group Number:

1) Defect Group numbered 1 shall be repaired first, followed sequentially by other defect groups.

2. Contractor reviews markings and initial assessment report.

3. Contractor holds a pre-work coordination meeting with the COR, to facilitate understanding between Contractor and Government of overall condition of runner. Contractor describes the anticipated effort associated with repairing high-and low-priority zones, and potential problems.

4. COR authorizes work on specific zones.

5. If, during surface preparation and repair activities, additional repair is identified, prepare a secondary assessment form documenting the needed repair.

48 13 13 - 5

6. Prior to performing repair work on newly identified zones, hold an additional pre-work coordination meeting with the COR to describe the newly needed repair and anticipated effort to repair.

7. Depending on the nature of needed repair and current activities, the Government may authorize additional work after designating high and low priority, and assigning a Defect Group Number.

8. Contractor performs repairs on authorized additional work.

1.10 PRE-WORK COORDINATION MEETINGS

A. Prior to performing turbine repair, meet with Government Representative.

B. Coordinate time and place of meeting with Government Representative at least 2 days before meeting.

C. Contractor attendees shall be at least the following:

1. Contractor onsite supervisor.

PART 3 EXECUTION

3.01 EXAMINATION

A. Review the damaged repair zones which the Government physically outlined with paint-stick, marker, chalk or other means. Cease work and notify COR if outlines or markings are unclear.

B. Review the Government’s initial assessment form. Cease work and notify COR if information provided in the Government’s initial assessment form is unclear or does not match visible conditions.

C. Continuously inspect surfaces for additional needed repair which may become visible during all stages of repair work. Needed repair includes defects such as:

1. Indications.

2. Cracks.

5. Centerline shrinkage.

6. Other apparent discontinuities.

48 13 13 - 6

3.02 SECONDARY ASSESSMENTS
