These two materials are being bid as one project. Only one contract will be awarded for this work.
Actual amounts to be crushed shall be determined based upon quantity and unit prices. The County has budgeted $500,000 for this work and reserves the right to add or delete quantity of material(s) to meet the budget. Crushed material quantity will be paid for by determining a rodded unit weight (ASTM C29) for product(s) and accompanying owner survey(s) to determine pile volume/weight.
All material up to 4 feet shall be crushed. Any material over 4 feet will be considered oversize. Material and pit area may be viewed by making an appointment with the Road Department. The exact location of material to crush and stockpile locations will be designated by the Flathead County Road Department at the time of crushing. Bidders are encouraged to contact the Flathead County Road Department if there are any questions or to set up a time to view the crushing site.
Bid proposals must be submitted on a form to be provided for the purpose, addressed to the Board of County Commissioners, Room 302, 800 South Main, Kalispell, MT 59901, and enclosed in an envelope marked, "Proposal for Crushing and Stockpiling Gravel."
No proposal will be considered unless accompanied by a proposal security in the amount of ten percent (10%) of the bid to secure the bidder's express covenant that if the bidder is awarded the contract, the bidder will, within ten (10) days, enter into a formal contract for the production and sale of said materials. Bid security shall be payable to Flathead County and shall be in the form of lawful money of the United States; a cashier's check, certified check, bank money order or bank draft issued by a Montana bank, or a bid bond executed by a surety corporation authorized to do business in Montana.
A performance bond will be required for the faithful performance of the successful contractor in the full amount of the bid.
Specifications, forms of contract, proposal blanks, and full instructions are on file and may be obtained at the Commissioner’s Office, at 800 South Main, Room 302, Kalispell, MT 59901.
Flathead County shall assess liquid damages of $200 per day for failure of the contractor to complete the contract in sixty (60) calendar days. This allows thirty (30) days for the contractor to file a public notice of moving and the State change of location notice. Extenuating circumstances will be considered by the County Commissioners for extension of the contract without penalty.
The successful bidder must contract to pay prevailing wage rates (Highway Construction Services) set by the Montana Department of Labor. The Contractor and all subcontractors will be required to have a certificate of registration from the Employment Relations Division of the Montana Department of Labor and Industry in the proper classification. The successful bidder must contract to give preference to the employment of bona fide residents of Montana in the performance of the work.

The successful bidder will also be required to provide proof of Workers’ Compensation insurance and/or an independent contractor certification from the State, as well as satisfy the County’s minimum insurance requirements.
