SCOPE OF WORK

BLOWER MOTORS LUBRICATION, ALIGNMENT AND VIBRATION ANALYSIS SERVICES AT THE NOGALES INTERNATIONAL WASTEWATER TREATMENT FACILITY.

A) BACKROUND

The US International Boundary and Water Commission (USIBWC) operates and maintains the Nogales International Wastewater Treatment Plant (NIWTP) in Rio Rico, Arizona. The NIWTP currently treats approximately 17 million gallons per day of raw sewage entering from Nogales, Mexico and Nogales, Arizona.

The NIWTP consists of a Biological Nutrient Removal (BNR), filtering and disinfection process. A critical component in this process is the air supply provided to the aeration basins by five centrifugal blowers (Spencer Series 6000) driven by 400 HP Baldor AC Induction Motors.

B) SCOPE OF WORK:

1) General: Provide all labor, tools, equipment, instruments and lubricants to services motors, perform alignment and vibration analysis of up to five motors at indicated intervals at the Nogales International Wastewater Treatment Plant (NIWTP) in accordance with the manufacturer’s recommendations. Personnel performing service work shall be qualified to work on Baldor motors.

2) Blower quarterly Preventive Maintenance:

· General inspection

· Bearing relubrication

· Take and record thermal readings

· Check and record voltage and current reading

· Provide PM report.

3) Blower semi-annual services:

· Perform laser alignment check

· Perform vibration analysis

· Provide report

C) HEALTH AND SAFETY:

The blower area requires hearing protection while motors are running due to high noise levels. The Contractor shall be responsible for implementing its own hearing protection plan and Lockout/Tagout plan. The contractor shall perform all work according to all applicable OSHA regulations and safety procedures and provide all the required Personnel Protective Equipment and monitoring instruments for its employees.
