Scope of Services:

This Scope of Services is intended to support the solicitation of proposals for up to a two (2) year agreement covering repair, replacement, and servicing of West Basin’s pumps and motors. If applicable, a Prime pump contractor shall partner with a local motor subcontractor(s) for this work.

Upon written (e-mail) approval from West Basin’s Project Manager (PM), Contractor(s) will perform the requested work on as-needed basis. The PM will discuss with Contractor(s) the particulars of a given equipment repair project, the cost and not-to-exceed price, and the appropriate level of effort. Urgent or emergency work may be authorized on a time and materials basis with appropriate proof of time and submitted receipts.

Once written approval is given by the PM, the selected Contractor will travel to the appropriate West Basin location, pick-up and/or remove the designated equipment in need of repair, and proceed with the agreed-upon repair, rebuild, or replacement task(s). Contractor(s) shall be responsible for disconnecting, removing, and palletizing (if feasible) the designated equipment, as well as the re-installation of the repaired and/or replaced equipment. Contractor(s) must be able to provide on-site pick-up and/or removal service (e.g. crane service) and subsequent return delivery service plus disconnection, removal, and reinstallation/reconnection of repaired equipment to any of West Basin’s wastewater treatment facilities and/or other equipment locations.

To verify pump efficiency, a post‐installation pump test may be required as part of the post-overhaul pump commissioning process. The selected Contractor(s) must be capable of measuring and recording pump operational parameters after equipment reinstallation, such as pump flow capacity, total head, discharge pressure, and kW input to motor. Pump performance criteria, such as system flow and pressure requirements, may also be required by West Basin during a post-installation pump test verification.

Non-emergency work will be scheduled in advance. Contractor(s) shall be able to meet the emergency response times described below:

During West Basin business hours (7:30am – 5:00pm, M-F)

• Respond to request for services within 1 hours from receipt of notification.

• For onsite required support: dispatch to site within 4 hours from receipt of notification.

Outside of West Basin business hours, holidays, and weekends

• For onsite required support: respond to site within 12 hours from receipt of notification.

• The Contractor’s proposal should describe their approach for responding to unscheduled emergencies and after-hours support response.

West Basin’s e-mail approval authorization(s) shall convey a separate and discrete billing task order number which is to be referenced on the Contractor’s associated invoice. Note: West Basin reserves the right to send staff to Contractor's facility in order to witness final inspection/test of the repaired equipment prior to return shipment to West Basin. Contractor(s) services and responsibilities shall include and be in accordance with Scope of Services established below. The selected contractor(s) shall be capable of providing the following services:

1. Must be capable of machining and/or fabricating parts if required.

2. For pump repair projects:

a. Repair or replacement of the pump bowls/volutes and/or impellers.

b. Machine work (e.g., facing, pit, and hole filling, replacing wear rings) to return pump bowl(s) or impeller(s) to original condition (or better).

c. Trimming of impellers

i. Impellers shall be at the trim needed to optimize the pump performance. The design should be such that at design load the motor will not be loaded beyond the nameplate rating and at no place on the pump curve shall the loading exceed the service factor.

d. Addition or removal of pump stage(s)

e. Post-installation pump performance testing services, including measurement or verification of:

i. Individual pump flow capacity

ii. Total head

iii. Discharge pressure

iv. kW input to motor
