PERFORMANCE WORK STATEMENT

SUMMARY OF WORK

Revised: 2/21/2020

PART 1 GENERAL

SUMMARY

This specification section provides detailed information of site and project requirements that are necessary for successful completion of the project. In addition to all specifications, the contract drawings set must be used and followed to obtain complete project requirements. A map of the project site can been found in the Appendix.

WORK COVERED BY CONTRACT DOCUMENTS

Project Description

The work includes mechanical alignment of the spillway Tainter gate drive shafts and incidental related Tainter gate work. The spillway section of Tuttle Creek consists of 18 Tainter Gates that are driven by 19 individual 2 HP motors (18 primary, 1 auxiliary). Each section of Tainter Gates has 6 coupled drive shafts and 6 pillow block bearings plus 2 couplings on the auxiliary motor side (218 total) that require adjustment within specified tolerances by shimming the associated components. The Tainter Gate drive shaft has a unique feature that allows operation of a Gate with the motor from an adjacent gate by use of special “cut-out” type couplings in the drive shafts. Work will include insuring that all 19 motor couplings (18 primary, 1 auxiliary) and all 19 cut-out couplings (18 primary, 1 auxiliary) engage without special tools 36 cut-out couplings (2 each per gate section) engage by hand using only a hex key.

Location

The work is located at Tuttle Creek Lake in Pottawatomie County, KS. See IM008 for location map.

CONTRACT DRAWINGS

The drawings are included in Appendix A of this specification. They are included for information only (FIO).

EXISTING WORK

The Contractor shall protect from damage all existing improvements and utilities (1) at or near the work site, and (2) on adjacent property of a third party, the locations of which are made known to or should be known by the Contractor. At the completion of operations, existing work must be in a condition equal to or better than that which existed before new work started.

The Contractor shall repair any damage to those facilities, including those that are the property of a third party, resulting from failure to comply with the requirements of this contract or failure to exercise reasonable care in performing the work. If the Contractor fails or refuses to repair the damage promptly, the Contracting Officer may have the necessary work performed and charge the cost to the Contractor.

PAYMENT

No separate measurement or payment will be made for work referred to in this section. All costs of operations here within shall be considered a subsidiary obligation of the Contractor to be included in the applicable contract unit price.

Payment for Winter Work

SPECIAL PROJECT INFORMATION

Water Management

The spillway Tainter gates are typically in a "dry" condition with no water on the radial portion of the system. If the Tuttle Creek pool elevation rises above 1116 feet, the tainter gates begin to impound water. Elevation 1116 feet is 41 feet above the multi-purpose pool and corresponds with approximately 52 percent of the flood control pool. The Contractor shall provide notice to the Contracting Officer's Representative (COR) and shall not operate the Tainter gates if pool elevations would result in a water release during gates movements.

If the pool elevation rises above 1105 feet, all gates shall be returned to operable order. The Government will notify the Contractor in the unlikely event that water levels rise to a level 1105 feet and that all onsite work will need to be postponed and all gates immediately returned to service. For this reason, the Contractor shall not take more than two

(2) gates systems out of service during the work on this contract at a single time. The Contractor shall be able to return all gates to functional service within a 48 hour notice by the Government.

Hazardous Energy Control

All Tainter gates shall be returned to the fully closed position and all controls and motors shall be de-energized upon the completion of each work day.

Fall Protection

The area where work is to be performed is on an elevated platform approximately 30-ft. above the concrete weir.

Access to some of the shaft components may require leaning over or exiting the catwalk. The Contractor shall mitigate any risk of worker injury in accordance with EM-385-1 Sect. 21, Fall Protection.

Coordination of Government Operating Equipment

The Contractor is authorized to operate the Tainter gate motors and controls. The Government will provide specialized training after contract award. The Contractor's employees shall not open, close, or tamper with switch valves, or control devices for existing installed equipment not specifically outlined in this scope.

Catwalk Access

The Tainter gates are accessed through a standard stair pathway and doors. All equipment used by the Contractor must be able to be carried through the doors and stairways to the work area. The Contractor shall insure that all doors are secured at the end of each work day.

Staging

An unsecured staging area will be provided by the Government for the Contractor as shown in Appendix B. The Contractor is permitted to store some items on the catwalk. Items left on the catwalk shall not impede safe access to the Tainter gates or create trip hazards. The Government reserves the right to request items be removed from the catwalk if they believe it would cause a dam or personnel safety related issue. Items left in the catwalk have potential to become damaged if when exposed to weather. The Government is not responsible for damage or theft to tools left on the catwalk or equipment left in the staging area. See IM009 for map of location.

TECHNICAL PROJECT REQUIREMENTS

The following technical requirements apply to all aspects of the contract.

Security

The Contractor is responsible for the security of all materials that have been procured as part of this project. Any damaged, lost, or stolen items, including those on site, shall be replaced at the Contractors expense.

Operational Tests

Pre-Work

Before work begins on any component, a pre-work operational test shall be performed with a government representative. The Contractor shall submit, for information only, a Pre-Work Operational Test Report documenting the initial operating condition of each major component. The Contractor shall create the report and it shall be signed by both the Contractor and the representative from the Government who witnessed the test. Any abnormal operating conditions including, but not limited to, noise, vibrations, overheating, etc, shall be documented in the report before work begins on the component. Digital pictures shall be included in the reports and audio clips and video shall be used to document the condition of all operating components before removal.

The Contractor shall record and submit to the Government the maximum travel achieved for each gate prior to triggering (if any) motor protection breakers (not to exceed 1-ft. of upward travel before lowering), the study state current draw to the motor in Amperes, the ambient temperature, the maximum amperage draw to the motor, and which (if any) Cut-Out Couplings (RD003, MK B-11) required disassembly in order to properly engage.

The Contractor shall submit a shaft alignment report for each of the couplings outlined in Section 2 to include Angular and Offset misalignment.

Post-Work

The Contractor shall record and submit to the Government the maximum travel achieved for each gate prior to triggering (if any) motor protection breakers (not to exceed 1-ft. of upward travel before lowering), the ambient temperature, and the steady state current draw to the motor in Amperes and the maximum amperage draw to the motor.

The Contractor shall submit a final shaft alignment report for each of the couplings outlined in Section 2 to include Angular and Offset misalignment.

Equipment Rigging

Some components may require rigging and/or lifting in order to properly perform shimming and alignment of the drive shafts. The contractor shall submit to any lifting plans prior to performing work.

Tainter Gates Out of Service

The Contractor shall limit the number of Tainter gates currently being worked on to two (2). The remaining sixteen

(16) gates shall remain fully operational at all times.

PART 2 PRODUCTS

SHAFT ALIGNMENT

Shaft Alignment Specifications

The Contractor shall use no more than five (5) shims per foot to achieve the desired alignment tolerances with preference given to thicker shims to use the minimum amount necessary.

Definitions:

Offset horizontal misalignment is where one shaft is moved horizontally away from the adjoining shaft, but both shafts are still in the same horizontal plane and parallel.

Offset vertical misalignment is where one shaft is moved vertically away from the adjoining shaft, but both shafts are still in the same vertical plane and parallel.

Angular horizontal misalignment is where the shaft is under an angle with the adjoining shaft but both shafts are still in the same horizontal plane.

Angular vertical misalignment is where the shaft is under an angle with the adjoining shaft but both shafts are still in the same vertical plane.

Motor Couplings

The coupling referenced as MK B-18 (19 total) on RD003 rotate at approximately 1800 RPM. The Contractor shall shim the Motor MK-3 and the Reducer MK B-5 to achieve the following maximum misalignment tolerances:

Angular Horizontal Misalignment (Mils per inch): 0.5/1 in.

Angular Vertical Misalignment (Mils per inch): 0.5/1 in.

Offset Horizontal Misalignment (Mils): 2.0 Offset Vertical Misalignment (Mils): 2.0

Reference RD002 for typical layout of components.

The Motor Couplings are "cut-out" type couplings that allow for the Tainter gates to be driven by the adjacent motor in the event of the primary motor failing. A set screw allows the coupling to "slip" and either disengage or engage the associated shafts. Currently, some of the Motor Couplings require complete disassembly and special tools in order to engage the shaft due to misalignment issues. The Contractor shall ensure that all Motor Couplings engage and disengage their associated shafts without disassembly while ensuring that the above referenced tolerances are achieved.

Break Shaft Couplings

The couplings referenced as MK B-14 (1 total) on RD003 for each of the eighteen (18) Tainter gate sections, rotate at approximately 300 RPM. The Contractor shall shim the components referenced as MK B-2, MK B-6, and MK B- 16 (3 total per section) to achieve the following maximum misalignment tolerances:

Angular Horizontal Misalignment (Mils per inch): 2.0/1 in.

Angular Vertical Misalignment (Mils per inch): 2.0/1 in.

Offset Horizontal Misalignment (Mils): 10.0 Offset Vertical Misalignment (Mils): 10.0

Reference RD002 for typical layout of components.

Floating Couplings

The couplings referenced as MK B-13 (2 total) on RD003 for each of the eighteen (18) Tainter gate sections rotate at approximately 300 RPM. The Contractor shall shim the components referenced as MK B-1, MK B-6, MK B-15, and MK B-16 (4 total per section) as well as adjust the Bearing Hanger Assemblies referenced as MK B-19 (3 total per section) to achieve the following maximum misalignment tolerances:

Angular Horizontal Misalignment (Mils per inch): 2.0/1 in.

Angular Vertical Misalignment (Mils per inch): 2.0/1 in.

Offset Horizontal Misalignment (Mils): 10.0 Offset Vertical Misalignment (Mils): 10.0

Reference RD002 for typical layout of components.

Rigid Couplings

The couplings referenced as MK B-12 (1 total) on RD003 for each of the eighteen (18) Tainter gate sections rotate at approximately 300 RPM. The Contractor shall adjust the Bearing Hanger Assemblies on either side of the coupling referenced as MK B-19 (2 total per section) to achieve the following maximum misalignment tolerances:

Angular Horizontal Misalignment (Mils per inch): 2.0/1 in.

Angular Vertical Misalignment (Mils per inch): 2.0/1 in.

Offset Horizontal Misalignment (Mils): 10.0 Offset Vertical Misalignment (Mils): 10.0

Reference RD002 for typical layout of components.

Cut-Out Couplings

The couplings referenced as MK B-11 (1 total) on RD003 for each of the eighteen (18) Tainter gate sections, plus MK B-11 on the auxiliary motor, rotate at approximately 300 RPM. The Contractor shall shim the components referenced as MK B-2 and MK B-5 (2 total per section), plus MK B-1 and MK B-5 on the auxiliary motor assembly, to achieve the following maximum misalignment tolerances:

Angular Horizontal Misalignment (Mils per inch): 2.0/1 in.

Angular Vertical Misalignment (Mils per inch): 2.0/1 in.

Offset Horizontal Misalignment (Mils): 10.0 Offset Vertical Misalignment (Mils): 10.0

Reference RD002 for typical layout of components.

The Cut-Out Couplings allow for the Tainter gates to be driven by the adjacent motor in the event of the primary motor failing. A set screw allows the coupling to "slip" and either disengage or engage the associated shafts.

Currently, some of the Cut-Out Couplings require complete disassembly and special tools in order to engage the shaft due to misalignment issues. The Contractor shall ensure that all Cut-Out Couplings engage and disengage their associated shafts without disassembly or use of tools other than a hex key while ensuring that the above referenced tolerances are achieved.

Additional Components

The following components as highlighted in Red on RD002 are not to be shimmed, adjusted, or in any way altered from their current position by the Contractor: MK C-1, MK C-2, MK C-3, and MK B-7.

Any components not explicitly outlined in these specifications that the Contractor deems necessary to adjust or shim to fulfill the performance requirements will require approval by the Government.

SHIMS

All shims used for alignment shall be new and free of any manufacturing defects. All existing shims from components that require adjustment shall be removed from service and replaced with new. Shims shall be 18-8

Stainless Steel with a minimum Rockwell Hardness of B70 or equivalent with Government approval. Shims less than or equal to 0.010" shall have a tolerance of +/- 0.0005". Shims greater than 0.010" shall have a maximum tolerance of +/- 0.004". Shims shall be appropriately sized for the associated bolt with the shim slot not to exceed the hold down fastener by more than 0.125" while allowing for 1/4" back-off once in place. Shims should provide at least 75% contact between each machined foot and its point of contact on a baseplate, frame, or soleplate.

FASTENERS

All fasteners removed during work shall be thoroughly cleaned prior to reassembly. Any fasteners damaged during disassembly or otherwise unfit for reassembly shall be replaced with equivalent at the Contractor's expense.

Torque Requirements for Fasteners

Torque requirements for each size of fastener shall be per the following charts (For exceptions, see below)

Threads shall be lubricated by use of liquid thread locking material or use of lubricant, if thread locking is not required. If Contractor has any questions concerning torque for bolts during re-assembly, contact the COR.

Torqueing Procedure

A moly paste (moly-disulfide) type of lubricant shall be used on the threads before applying torque. The bolt shall be initially hand tightened and then made snug. The bolts shall then be torqued down incrementally in a star/crisscross pattern in 25 percent increments until the final torque is achieved.

Reassembly of Components

All parts to be reinstalled shall be thoroughly cleaned as required to provide a fully functioning system. Rust, dirt, grit and other foreign matter shall be removed. Holes and grooves for lubrication and all bushings or bearings shall be cleaned before reassembly. Bushings or bearings shall be pre-lubricated with appropriate grease or lubricant before assembly. Enclosed chambers or passages shall be examined to make sure that they are free from foreign materials. Pipe wrenches, cold chisels or other tools likely to cause damage to the surfaces of shafts, nuts, or other parts shall not be used for assembling and tightening parts. Bolts and screws shall be tightened firmly and uniformly, but care shall be taken not to overstress the threads. When a half nut is used for locking a full nut, the half nut shall be placed first and followed by the full nut. Threads of all bolts, nuts and screws shall be lubricated with an approved lubricant before assembly (unless a thread locking material is required). Threads of corrosion resisting steel bolts and nuts shall be coated with an approved anti-galling compound. Driving and drifting bolts or keys will not be permitted.

Each machinery or structural unit shall be accurately aligned so that no binding in any moving parts or distortion of any member occurs during operation. The alignment of all parts with respect to each other shall be true within the respective tolerances required. Components shall be set true to the original plans as shown on the drawings.

Services Summary

The services summary provides performance objectives that related directly to mission essential items. The performance threshold briefly describes the minimum acceptable levels of service required for each requirement.

These thresholds are critical to mission success. Successful completion of this PWS by the Contractor will be determined by achieving the provided tolerances for shaft misalignment as outlined in the specifications.
