Presolicitation_Notice_LMDT_Dewatering_Wells___Pumps_Maintenance_1.pdf

The Missouri Basin Region of the Bureau of Reclamation, Eastern Colorado Area Office, intends to issue a Request for Quotation (RFQ) for a firm fixed-price purchase order to perform annual & biennial maintenance for three groundwater pumping wells and their 100HP vertical turbine pumps located near 749 Highway 91, Leadville, Colorado.

This maintenance on the wells and the pumps must be performed concurrently, but offerors are welcome to provide a quote to perform maintenance on only the wells, on only the pumps or on both the wells and the pumps. If an offeror chooses to provide a quote to perform maintenance on only the wells, that offeror will be required to affirm they agree to work in good faith with the government and the other contractor performing maintenance on the pumps (or vice-versa).

• Motors will be disconnected by Reclamation staff

• Remove two (2 each) existing 100 HP motors and vertical turbine pumps

(approximately 130 feet of 8-inch column pipe and shaft/ oil tube) from each well.

Bring enough cribbing to lay out 20-foot lengths of pipe and shaft on the ground adjacent to wells.

• Conduct pre-cleaning video of each well per Task 2.

• Inspect pumps to verify that shafts, oil tubes, bearings, and impellers are in good working condition, rebuild pump bowls, and ensure there are no restrictions effecting flow or performance curves.

• After wells have been cleaned and post-clean video inspection is complete per

Task 2, Return to work site and replace pumps, oilers, and motors per AWWA

TASK 2: Alternate-year (every 24 months) Dewatering Wells 1 & 2 at Station 10+25

• Video camera (high quality resolution) inspection of both well casings and screened portions of wells, prior to cleaning to assess level of scaling obstruction on screens since last cleaning.

• Clean well screens using an up to 10,000 psi hydro-jetting or equivalent method to remove heavy calcium and iron precipitate scaling.

• For jetting Wells 1 and 2, water can be pumped from the opposite well. Wells are approximately 30 feet apart. Contractor may also supply their own water.

• Additional materials provided by contractor and required for this Task include:

o Three (3) 5-gallon buckets of Chevron Rando 32 or equivalent turbine drip oil o 30 – 2 ½” ID PVC vinyl end caps to seal oil tube/shaft ends to prevent contamination during transportation and cleaning of column pipe sections o 30 – metal band straps for securing 1” pvc level sounding tube to outside of 8” column pipes
