Subsections 102.06 and 102.07 shall be deleted and replaced with the following:

102.06 Preparation of Bid. The bidder shall submit the bid upon the forms furnished by the County. The bidder shall specify a unit price for each pay item for which a quantity is given and shall also show the mathematical products of the respective unit prices and the estimated quantities in the column provided for that purpose, together with the total amount of the bid obtained by adding such mathematical products.

When the bid contains an alternative pay item, which has been approved by the County, the choice of that item by the bidder shall be indicated in accordance with the specifications for that particular item. No further choices will be permitted.

The contractor's bid must be signed by an individual with legal authority to bind the contractor. Anyone signing as agent for a contractor must file with the County written evidence of such authority.

(a) Bid Guaranty. A bid will not be read and will be rejected unless accompanied by a guaranty of the character and in an amount not less than the amount indicated in the "BIDDING INSTRUCTIONS" statement, found in the Invitation to Bid Package. The bid Guaranty shall be a bid bond in the format presented in the Bid Package. No other wording will be accepted.

Bids must be submitted and must be complete. An incomplete bid, a bid without complete signature(s), or a bid not in the approved form, including submission by telephone or facsimile machine, will not be accepted, or considered but will be rejected.

(e) Opening of Bids. Bids shall be opened and read publicly at the time and place specified in the Invitation to Bid or Addendum. Such opening shall be performed by an authorized employee of Larimer County in the presence of at least one witness. Contractors, their authorized agents, and other interested parties are invited to be present.

(f) Rejection of Individual Bids. Individual bids may be rejected for any of the following reasons:

1. If the bid is on a form other than that prescribed by Larimer County, if the form is altered or any part thereof is detached, or if the form is not signed by an authorized agent.

2. If there are unauthorized additions, conditional or alternate bids, or irregularities of any kind which may tend to make the bid incomplete, indefinite, or ambiguous.

3. If the contractor fails to acknowledge in the bid that it has received all addenda (if any) current on the date of opening of bids.

These costs shall all relate to the performance of the items in question. The materially unbalanced bid is a mathematically unbalanced bid which Larimer County determines leaves reasonable doubt that award will result in the lowest ultimate cost to the County, or that award is in the public interest.

7. If the contractor submitting the bid has been asked in writing to show why it should not be found in default on a Larimer County contract.

8. If the contractor submitting the bid has had its prequalification by the Colorado Department of Transportation revoked, or if the contractor submitting the bid is currently under debarment or suspension by the Colorado Department of Transportation.

Larimer County reserves the right to reject any or all bids, to waive technicalities, to further negotiate price, scope of work, terms, and conditions with the successful bidder, or to advertise for new bids, if, in the judgment of Larimer County, the best interests of Larimer County will be promoted thereby.

In the event of low tie bids, a drawing shall be conducted to determine the low bidder. A witness shall be present to verify the drawing, and the result shall be certified on the bid tabulation.

Larimer County reserves the right, in its sole discretion, to reject any subcontractor of the successful bidder, and to further negotiate for a substitute subcontractor.

The County reserves the right to settle bid discrepancies, as defined in this subsection and in subsection 102.06, that occur in the low bidder's bid at the time the Contract is awarded. Bid discrepancies will be settled with the understanding that the low bidder waives any claims against the County because of the bidder's mistakes in the bid.

103.03 Requirement of Contract Bond. At the time of the execution of the contract, the Contractor shall furnish Performance and Payment Bonds, each in a penal sum equal to the estimated contract price as per "Bid Schedule" hereto attached, with surety or sureties to guarantee the completion of work and also to guarantee that all material and labor upon this work, or incidental to the completion of this work shall be fully paid for.

(ii) above, the Contractor shall, within five (5) days thereafter, substitute another Bond and Surety, both of which shall be acceptable to the County.

In subsection 103.04 delete the first two sentences and replace with the following:

The contract shall be signed by the successful bidder and returned, together with the Contract Bonds and Insurance Certificates and Endorsements, within 15 days after the date of award.

103.05 Failure to Execute Contract. Failure of the low responsible bidder to so execute the contract and file acceptable contract bonds and insurance certificates and endorsements within fifteen (15) calendar days or other duration specified by the County after the date of award shall be just cause for the cancellation of the award and the forfeiture of the bid guarantee which shall become the property of the County. The County may elect to waive forfeiture of the bid guarantee only if the County determines that the low responsible bidder has made a good faith error, which was an honest, nonjudgmental error, not the result of intentional conduct, gross negligence or willful neglect, and that no damages were sustained by the County as a result of the failure by the low responsible bidder to execute the contract and file acceptable contract bonds and insurance endorsements within the time prescribed.
