Subsection 102.04 delete the first sentence and replace with the following:

Any change to bid forms, plans, or specifications prior to the opening of bids will be posted on the Bidnet portal. It is the contractor’s responsibility to check the website for these changes. This portal can be found at https://www.bidnetdirect.com/colorado/larimer-county/

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.

A bid may not be withdrawn after the time set for opening of bids. https://www.bidnetdirect.com/colorado/larimer-county/ https://www.bidnetdirect.com/colorado/larimer-county/ https://www.bidnetdirect.com/colorado/larimer-county/ https://www.bidnetdirect.com/colorado/larimer-county/ https://www.bidnetdirect.com/colorado/larimer-county/

(d) Receiving Bids. Bids will be received by Larimer County at the time and via the format specified in the Invitation to Bid until the time and date specified in the Invitation to Bid or Addendum.

Bids must be submitted 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.

103.01 Consideration of Bids. After the bids are opened and read, they will be compared on the basis of the summation of the mathematical products of the estimated quantities shown in the bid schedule and the unit bid prices. The results of such comparisons will promptly be made available to the public.

In the event of a discrepancy between unit bid price and the mathematical products of the unit bid price and the estimated quantities in the bid schedule, the unit bid price shall govern.

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.

Colorado resident bid preference. A resident bidder shall be allowed a preference against a non-resident bidder from a state or foreign country equal to the preference given or required by the state or foreign country in which the nonresident bidder is a resident.

Resident bidder means:

(a) A person, partnership, corporation, or joint venture which is authorized to transact business in

Colorado and which maintains its principal place of business in Colorado; or

(b) A person, partnership, corporation, or joint venture which is authorized to transact business in

Colorado, which maintains a place of business in Colorado, and which has paid Colorado unemployment compensation taxes in at least seventy-five percent of the eight quarters immediately prior to bidding on a construction contract for a public project.

The bids will be treated as follows:

(a) All bids will be checked for accuracy by the County.

(b) The dollar amount of the checked bid from non-resident bidders will be adjusted by a percent-age equal to the preference percentage given or required by the state or foreign country of the bidder's residency. If the state or foreign country does not give or require a residency preference, no adjustment in the bid dollar amount will be made.

(c) Adjusted bids from non-resident bidders will then be compared to bids from resident bidders, and the bidder with the lowest total will be considered the apparent low bidder.

(d) Should a non-resident bidder be the apparent low bidder, in accordance with paragraph (3) above, an award will be made on the basis of the original bid, not the adjusted bid.

(e) The County will proceed with its normal award procedure.

Subsection 103.03 shall be deleted and replaced with the following:

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. These Bonds shall remain in effect at least until one year after the date of final payment, except as otherwise provided by law. The Contractor shall also furnish such other bonds as are required herein. All bonds shall be executed using Larimer County standard forms and shall be executed by such Sureties as (i) are licensed to conduct business in the State of Colorado, and (ii) are named in the current list of "Companies Holding Certificates of Authority as Acceptable Sureties on Federal Bonds and as Acceptable Reinsuring Companies" as published in Circular 570 (amended) by the Audit Staff Bureau of Accounts, U.S. Treasury Department. All Bonds signed by an agent must be accompanied by a certified copy of the authority to act.

If the Surety or any Bond furnished by the Contractor is declared a bankrupt or becomes insolvent or its rights to do business is terminated in the State of Colorado or it ceases to meet the requirements of clauses (i) and (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. If the signed contract, bonds, certificates and endorsements are returned by the successful bidder within 15 days after award and, if the contract is not executed by the County within 30 days from date of award, the bidder shall have the right to withdraw his bid without penalty.

Subsections 103.05 is hereby added to the Standard Specifications and shall include the following:

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. Award may then be made, in accordance with the provisions of Subsection 103.02 to the next lowest responsible bidder, or the work may be re-advertised.

The Contractor shall furnish an approved 10 foot straightedge and depth gauge and provide an operator to aid the Engineer in testing the finished pavement surface. Areas to be measured shall be as directed by the Engineer. Areas showing high spots of more that 3/16 inch in 10 feet shall be marked and diamond ground until the high spot does not exceed 3/16 inch in 10 feet. Additional diamond grinding shall be performed as necessary to extend the area ground in each lateral direction so that the lateral limits of grinding are at a constant offset from and parallel to the nearest lane line or pavement edge, and in each longitudinal direction so that the grinding begins and ends at lines normal to the pavement centerline within the ground area. All ground areas shall be neat rectangular areas of uniform surface.

Diamond grinding, including all necessary traffic control, shall be completed at the Contractors expense.

On asphalt pavements, the diamond grinding shall not reduce planned pavement thickness by more than 0.3 inch and the entire ground area shall be covered with a fog seal coat when grinding is complete. On concrete pavements, the diamond grinding shall be completed prior to joint sealing and prior to determining pavement thickness in accordance with subsection 412.21.

(a) Removal and replacement. The pavement in areas requiring corrective work shall be removed the full width of the lane and the full thickness of the course in accordance with Subsection

202.09 Removal of Asphalt Mat (Planing).

The removal area shall begin and end with a transverse butt joint, which shall be constructed with a transverse saw cut perpendicular to centerline. All replacement shall be made with approved hot mix asphalt mixtures that meet all contract requirements. Replacement material shall be placed in sufficient quantity so the finished surface will conform to grade and smoothness requirements. The corrective area shall be compacted to the specified density.

(b) Overlay. The overlay shall cover the full width of the pavement including shoulders. The area overlaid shall begin and end with a transverse butt joint which shall be constructed with a transverse saw cut and asphalt removal. All material shall be approved hot mix asphalt mixtures that meet all contract requirements. The overlay shall be placed so the finished surface will conform to grade and smoothness requirements. The overlaid area shall be compacted to the specified density. The overlay thickness shall be equivalent to that of the final pass made in accordance with the plans and specifications.

If roadway smoothness exceeds the limits allowable for diamond grinding, corrective work on concrete pavements shall consist removal and replacement. Corrective work on concrete pavements shall conform to the following conditions:

Removal and Replacement. The pavement areas requiring corrective work shall be removed the full width of the lane and full length of the slab between horizontal control joints and shall be jointed in accordance with M-412-1
