C. Retail sales/use taxes, if any, payable on equipment, materials and other items provided hereunder to the Contractor by the County shall not be included in the Bidder’s proposed prices. If taxes on such items are required to be paid, the County shall make such payment, either through the Contractor or direct to the Washington State Department of Revenue.

3.04 BID ERRORS, INFORMALITIES AND IMMATERIAL IRREGULARITIES

A. Prices set forth in the bid will be reviewed by the County for mathematical accuracy.

B. The County, in its sole discretion, reserves the right to waive minor bid errors, informalities, and immaterial irregularities when it is in the County’s best interest and does not result in displacement of a low bidder.

C. The County reserves the right to correct arithmetical errors and discrepancies between unit prices(s) and extended amount(s) and/or written words or numbers (collectively referred to herein as a “Discrepancy”) under the following circumstances:

1. Existence of the Discrepancy is ascertainable from the face of the bid;

2. The Bidder verifies Discrepancy;

3. The intended bid is ascertainable from the face of the bid; and

4. Correction of the Discrepancy does not result in displacement of a low Bidder.

Where 1. through 4. are met, the unit price will always prevail.

D. Where the bid is readily susceptible of being interpreted as offering either one of two prices shown on the face of the bid, one of which is low and the other is not, the bid must be rejected. If the evidence of the arithmetical error or discrepancy is clear and convincing the Bidder may be permitted to withdraw its bid.

E. In the event a Bidder believes it made an error on its bid, the Bidder shall provide written notice of such claim. The Bidder shall provide to the County supporting evidence for such claim including cost breakdown sheets. The County reserves the right to require the submittal of other bid records or information as the County may deem necessary to evaluate the Bidder’s claim of error, or any error as may be identified by the County during its review of the bid.

F. Any review by the County of a bid and/or any review of such a claim of bid error (including supporting evidence) creates no duty or liability on the County to discover any other bid error or mistake, and the sole liability for any bid error or mistake rests with the Bidder or Contractor.

https://kingcounty.gov/procurement/solicitations D. Reciprocal Preference for Resident Contractors

1. In accordance with RCW 39.04.380, the County is enforcing a Reciprocal Preference for Resident Contractors. Any public works bid received from a Nonresident Contractor from a state that provides a percentage bidding preference, a comparable percentage disadvantage must be applied to the bid of that Nonresident Contractor. States that currently provide bidding percentage preferences to resident contractors are: Alaska, Nevada, New Mexico and Wyoming.

2. A “Nonresident Contractor” is a contractor that:

https://kingcounty.gov/procurement/solicitations

Rev. 7/7/2026 00 20 00 - 9 Instructions to Bidders

(a) is from a state that provides a percentage bid preference to its resident contractors bidding on public works contracts; and

(b) at the time of bidding on a public works project, does not have a physical office located in Washington.

3. The state of residence for a Nonresident Contractor is the state in which the contractor was incorporated or, if not a corporation, the state where the contractor’s business entity was formed.

4. All Nonresident Contractors will be evaluated by the County for an out of state percentage bidding preference. If the state of the Nonresident Contractor provides a contractor percentage bidding preference, a Comparable Percentage Disadvantage (“CPD”) will be applied, by the County, to the Nonresident Contractor’s Total Bid Price during bid evaluation. The CPD is the percentage bidding preference advantage, provided by the Nonresident Contractor’s home state.

5. For the purpose of determining the low bidder, the County shall multiply the Nonresident Contractor’s Total Bid Price by the CPD. The CPD shall be added to the Nonresident Contractor’s Total Bid Price which equates to the Nonresident Contractor’s Disadvantage Total Bid. This Nonresident Contractor’s Disadvantage Total Bid shall be compared to the other bidder(s) Total Bid Price(s) for the solicitation and the bidder with the lowest total bid shall be the low bidder for this solicitation. See example below.

EXAMPLE:

Alaska Nonresident Contractor’s Total Bid Price $100,000 Multiplied by the Alaska CPD x 0.05 Alaska CPD Total $ 5,000

Alaska Nonresident Contractor’s Total Bid Price +$100,000 Alaska CPD Total $ 5,000 Nonresident Contractor’s Disadvantage Total Bid $105,000*

* NOTE: If the Nonresident Contractor’s Disadvantage Total Bid is lower than the other bidder(s) Total Bid Price(s), the Alaska Nonresident Contractor will be the low bidder, and if found responsible, will be awarded a contract for the Total Bid Price of $100,000.

If the Nonresident Contractor’s Disadvantage Total Bid is higher than the other bidder(s) Total Bid Price(s), the bidder with the lowest Total Bid Price, if found responsible, will be awarded a contract for their Total Bid Price.

3.06 QUALIFICATIONS OF BIDDER

A. In accordance with RCW 39.04.350 the low responsive bidder shall demonstrate, to the satisfaction of the County, that the Bidder and/or its project team are responsible and qualified to perform the Work under this Contract. §00 45 13, Responsibility Detail Forms of the Contract Documents contains the mandatory and, if any supplemental criteria, for Bidder responsibility.

B. By conducting a bid evaluation conference, the County does not waive its right to make determinations regarding responsiveness and responsibility of the Bidder.

3.08 SINGLE BID RECEIVED

A. If the County receives a single responsive, responsible bid, the County shall have the right, at its sole discretion, to conduct a price or cost analysis on such bid. The Bidder shall promptly provide all cost or pricing data, documentation, and explanation requested by the County to assist in cost and price analysis. By conducting such analysis, the County shall not be obligated to accept the single bid; the County reserves the right to reject such bid or any portion thereof.

and (2) "cost analysis" means the review and evaluation of the separate cost elements and proposed profit of (a) the Bidder's cost or pricing data, and (b) the judgmental factors applied in projecting from the data to the estimated costs, in order to form an opinion on the degree to which the proposed costs represent what the contract should cost, assuming reasonable economy and efficiency.
