4.3.1. Submit bid pricing on the included Exhibit C Payment Schedule. Bid using only the units of measure

will be dropped and will not be recognized by the County for the purposes of bid evaluation,

contract award, or invoicing. The County will only use the first two digits after the decimal

points without rounding up or down. If the County calculates a “new” unit price, said unit

price will be in favor of the County and may be below the Contractor’s original bid price.

The “new” unit price shall prevail over Contractor’s original bid price and shall be used in

evaluation of bids, award, and invoicing.

4.3.2. All prices and notations must be clearly legible and in ink or typewritten. No erasures permitted.

Mistakes may be crossed out and corrected and must be initialed in ink by person signing the bid.

4.3.3.

Submitted bid prices must be balanced (reflecting the true relative costs of the bid items), and not

shift costs from one portion of the work to another portion of the work so as to place doubt on

whether the bid will result in the lowest overall cost to the County or be tantamount to allowing an

advance payment.

4.3.4. Unless otherwise specified, all prices shall be F.O.B. destination.

4.3.5. Prices shall include all freight and/or delivery charges, unless freight or delivery charges are

separately itemized or otherwise allowed for in the Payment Schedule.

Unless otherwise specified, prices bid herein should NOT include California sales/use tax or Federal

excise tax. The County generally is required to pay California sales/use tax, and it should be shown as

a separate item on invoices. The County is exempt from payment of Federal excise tax. It must NOT

be included in invoices.

4.3.7.

You may offer payment terms more favorable to the County than NET 30, which the County may or

may not accept at its sole discretion. Do not calculate such prompt payment discounts into your bid

prices. Prompt payment discounts will not be considered in evaluation of bids to determine low

bidder.

4.3.8. Prices shall be fixed during the performance of the Agreement and not subject to adjustment except as

explicitly set forth in the Agreement. Bidder accepts the risk of any changes to bidder’s costs during

the term of the Agreement.

4.3.9.

of bids. They represent approximate anticipated use based on historical consumption or other

estimates. If the County’s actual requirements do not result in orders in the quantities described as

estimated in the Payment Schedule, that fact shall not entitle the successful bidder(s) to price

adjustment or other relief.

DEPARTMENT OF AIR POLLUTION CONTROL DISTRICT

AS-NEEDED AIR PURIFIERS WITH REPLACEMENT FILTERS

4.3.10. The County of San Diego intends to expend federal funds for contract(s) resulting from this

solicitation. 2 CFR § 200.324 requires that pricing and profit margin be negotiated prior to award if

only one responsive bid is received from a responsible bidder. Failure to provide sufficient cost and

pricing information for such negotiations may be cause for the County to find Offeror’s bid non-

responsive.

5. BID EVALUATION

5.1. Award will be made to the lowest priced responsive bid(s) from a responsible bidder(s). The determination of

lowest price shall include the application of the Small-Local Business preference, when applicable.

5.1.1. Award may be based on total bid amount, distinct lots, or individual items (“Basis of Award”).

5.1.2. In the event of a conflict between a unit price bid and the extended price, the unit price will prevail

unless the conflict is a result of a Mistake in Bid. In that event, the bid will be rejected as non-

responsive.

5.1.3. In the event of a tie bid between responsible bidders, award will be by random selection through a

process determined by County and observable by the bidders involved in the tie.

5.2. Reserved.

5.3. Reserved.

5.4. Brand Name or Equal

5.4.1.

If items in this RFB have been identified as brand name “or equal,” such identification establishes a

quality standard and is not intended to limit competition. Other brands will be considered for award if

their products are determined by the County to be of equal or greater quality and to meet the County’s

requirements.

5.4.1.1. Bidder shall clearly identify the brand name of items that are not of the brand specified by

the County. Bids shall be considered as offering the specified brand unless otherwise

indicated in the bid.

5.4.2. The County’s evaluation as to equality of a product offered by a different brand shall be based upon

the information furnished in the bid, as well as other information known to the County. It is the

Offeror’s responsibility to provide sufficient information for evaluation.

shall include in the bid a clear description of such modifications.

5.4.2.2. Modifications proposed after bid submission will not be considered.

5.4.3. Reserved.

5.5. In evaluating an Offeror’s ability to satisfy the requirements of this RFB and any resulting contract, the County

may also consider any parent, subsidiary, or related legal entity of Offeror, including, without limitation, a legal

entity that Offeror acquired or merged with or will use as a guarantor in providing services to the County.

5.6. When evaluating Offeror’s bid, County will appropriately consider the proposed purchase, acquisition, or use

of goods, products, and materials produced in the United States in accordance with 2 CFR § 200.322.

6. EVALUATION AND SELECTION PROCESS

6.1. Bids received timely will be opened publicly following the due date and time.

6.2. Bids received and the abstract of responses will be posted to BuyNet after the bid opening.

6.3. The posted bid opening abstract of responses serves as Notice of Intent to Award (“NOI”) to the apparent low

bidder(s).

6.3.1. The County may rescind or modify the NOI at any time if the County otherwise determines that it is

in its best interest to do so.
