General Information
The following policies shall apply to sealed bids:

1. Bid or Proposal Opening: Bids will be opened at the time and date specified on the bid request. All bids are opened publicly and read aloud, with a tabulation provided to all vendors participating. Proposals for extensive systems, complicated equipment, or construction projects, with prior approval of the governing body, may be opened privately in cases where the disclosure of the contents of the proposal could not readily be evaluated and would have a negative impact on both the vendor and the city.

2. Electronic Bids: The invitation for bids shall be distributed electronically and bids shall be considered when they are received in hand at the designated office if by the time and date set for receipt of bids. Such electronic bids or proposals shall contain specific reference to the Invitation for Bids; the items, quantities, and prices for which the bid is submitted; the time and place of delivery; and a statement that the bidder agrees to all the terms, conditions, and provisions of the Invitation for Bids.

3. Late Bids: No bids received after closing time will be accepted. All late bids will be returned unopened to the vendor. Bids postmarked on the bid opening date but received after the specified time will be considered late and will be returned unopened.

4. Bid Opening Schedule: The Purchasing department is responsible for setting bid opening dates and times.

5. Telephone Bids: The Purchasing department will not accept any bid by telephone.

6. Bid Form: The Purchasing department sends duplicate copies of bid request forms to each bidder, thereby enabling the bidder to return one and maintain a file copy. Bids will not be accepted on any vendor letterhead, vendor bid form, or other substitutions unless special permission is given by the purchasing department.

7. Unsigned Bids: Failure of a vendor representative to sign a bid proposal removes that bid from consideration. A typed official's name will not be accepted without that person's written signature.

8. Acceptance of Bids: The city reserves the right to reject any or all bids, to waive any irregularities in a bid, to make awards to more than one bidder, to accept any part or all of a bid, or to accept the bid (or bids) that in the judgment of the governing body is in the best interest of the city.

9. Shipping Charges: Bids are to include all shipping charges to the point of delivery. Bids will be considered only on the basis of delivered price, except as otherwise authorized by the governing body.

10. Sample Product Policy: The purchasing department may request a sample product as part of a bid. If this is stated on the bid proposal form, the vendor is required to comply with this request or have the bid removed from consideration.

11. Approved Equal Policy: Specifications in the request for bid are intended to establish a desired quality or performance level or other minimum requirements that will provide the city with the best product available at the lowest possible price. When a brand name or model is designated, it signifies the minimum quality acceptable. If an alternate is offered, the bidder must include the brand name or model to be furnished, along with complete specifications and descriptive literature and, if requested, a sample for testing. Brands or models other than those designated as "equal to" products shall receive equal consideration.

12. Alternate Bids: Should it be found, after bids have been opened, that a product has been offered with an alternative specification and that this product would be better for the city to use, all bids for that item may be rejected and specifications redrawn to allow all bidders an equal opportunity to submit bids on the alternate item.

13. Vendor Identification: Potential suppliers are selected from existing vendor files using department's suggestions and any and all sources available to locate vendors related to a specific product or service. New suppliers are added to the bid list as they are found.

14. Tie Bids: A tie bid is one in which two or more vendors bid identical items at the same unit cost. The winning bidder among tie bids may be determined by one of the following factors:

  • Discount allowed
  • Delivery schedule
  • Previous vendor performance
  • Vendor location
  • Trade-in value offered

15. Cancellation of Invitation for Bid or Request for Proposal: An invitation to bid, a request for proposal, or other solicitations may be canceled, or any or all bids or proposals may be rejected in part as may be specified in the solicitation when it is in the best interest of the city. The reasons shall be made a part of the bid or proposal file.

16. Public Advertisement: In addition to publication in a newspaper of general circulation as required by law, the purchasing agent may make any other efforts to let all prospective bidders know about the invitation to bid. This may be accomplished by delivery, verbally, mail, or by posting the invitation to bid in a public place. It is not required that specifications be included in the invitation to bid. However, this notice should state clearly the purchase to be made.

17. Mistakes in Bids: Mistakes in bids detected prior to bid opening may be corrected by the bidder withdrawing the original bid and submitting a revised bid prior to the bid opening date and time. Bidder mistakes detected by the bidder after the bids have been opened based on miscalculation may be withdrawn only with the approval of the purchasing agent. The purchasing agent shall determine if all or a portion of any bid bond shall be surrendered to the city as liquidated damages for any costs associated with the bid withdrawal.

18. Bid Bond: The purchasing agent may require that bidders submit a bid bond or other acceptable guarantee equal to 5 percent of the bid to ensure that the lowest responsible bidder selected by the board enters into a contract with the city. All or a portion of the bid bond shall be surrendered to the city as liquidated damages should the successful bidder fail to enter into a contract awarded by the board.

19. Performance Bond: The purchasing agent may require and then include in the bid documents a requirement for the successful bidder to post a performance bond or other guarantee satisfactory to the city attorney that insures the faithful performance of all of the terms and conditions of the purchase contract.

20. Sealed Bids and Sealed Proposals: The following is taken from The Model Procurement Code for State and Local Governments, American Bar Association, February, 1979. Pages 21-22.

(a) "Competitive sealed bidding as defined in this Code, is the preferred method of procurement. Although the formal sealed bid process should remain a standard in public purchasing, there is a place for competitive negotiation' (State and Local Government Purchasing. The Council of State Governments (1975) at 2.2). The competitive sealed proposal method (similar to competitive negotiation) is available for use when competitive sealed bidding is either not practicable or not advantageous.
(b) Both methods assure price and product competition. The use of functional or performance specifications is allowed under both methods to facilitate consideration of alternative means of meeting [state] needs (with evaluation and where appropriate) on the basis of total or life cycle costs. The criteria to be used in the evaluation process under either method must be fully disclosed in the solicitation. Only criteria disclosed in the solicitation may be used to evaluate the items bid or proposed.
(c) These two methods of source selection differ in the following ways:

  • Under competitive sealed bidding, judgmental factors may be used only to determine if the supply, service or construction item bid meets the purchase description. Under competitive sealed proposals, judgmental factors may be used to determine not only if the items being offered meet the purchase description, but may also be used to evaluate competing proposals. The effect of this different use of judgmental evaluation is that under competitive sealed bidding, once the judgmental evaluation is completed, award is made on a purely objective basis to the lowest responsive and responsible bidder. Under competitive sealed proposals, the quality of competing products or services may be compared and trade-offs made between price and quality of the products or services offered (all as set forth in the solicitation). Award under competitive sealed proposals is then made to the responsible offer or whose proposal is most advantageous to the [state].
  • Competitive sealed bidding and competitive sealed proposals also differ in that, under competitive sealed bidding, no change in bids is allowed once they have been opened, except for correction of errors in limited circumstances. The competitive sealed proposal method on the other hand, permits discussions after proposals have been opened to allow clarification and changes in proposals provided that adequate precautions are taken to treat each offer fairly and to ensure that information gleaned from competing proposals is not disclosed to other offers.

*Unless lowered or increased to a maximum of $10,000 by the governing body.
