W.O. 20-32, Water Treatment Plant Sediment Hauling, will excavate and haul approximately 13,500 cubic yards of river sediment to the landfill.  The Water Treatment Plant dredges the sedimentation basins on a yearly basis and places the material into drying beds.  Once the material is dry, it is hauled to a designated site.

The project was advertised on February 28th, and March 6th, 2020, in the Yellowstone County News and on the City's website. Bids were opened on March 10th, 2020, and seven bids were received. Winkler Excavating Inc. submitted the lowest responsible bid.

City Council may:

• Approve the construction contract with Winkler Excavating, Inc. for W.O. 20-32 Water Treatment Plant Sediment Hauling in the amount of $110,650.00, or;
• Do not approve the construction contract.  If the project is not constructed, the Water Plant will not have sufficient room in the drying beds to dredge the sedimentation basins which will make it problematic to get the raw water into the treatment process to provide drinking water to the City.  

The following bids were received and evaluated:

Contractor	Bid Amount
Warren Transport, Inc.	$127,320.00
Firstmark Construction LLC	$124,705.00
Millennium Construction	$258,773.00

Olympus Technical Services	$150,800.00
Knife River	$142,650.00
Askin Construction	$115,260.00

Water funds budgeted in FY20 will be used for this project. The O&M Budget has sufficient funds available to meet the $650 overrun. The bids are based on an estimate of the tonnage of sediment.  Payments will be based on actual weights.  Historically, estimates have been higher than actual amounts so if that occurs under this project, the final cost may be less that the contract amount.  

Budgeted Amount	$110,000.00
Previously Encumbered	$0
This Contract	$110,650.00
Remaining Budget	($650)

 

Staff recommends that the City Council approve a contract with Winkler Excavating, Inc. for W.O. 20-32 Water Treatment Plant Sediment Hauling in the amount of $110,650.00.
