RESPONSES: Your response is due through electronic upload to BuyNet on the specified close date and time, local San
Diego time. If Offeror is unable to submit via BuyNet for any reason, Offeror may submit by email or mail to the listed
Contracting Officer, or by personal delivery to the Purchasing and Contracting front desk. Please use these methods only if
unable to submit through BuyNet. If mailed or delivered, the above RFQ No. should be included on the front of the envelope.
It is the Offeror's responsibility to submit based on the most current RFQ, addenda thereto, responses to Questions, any
other information posted on BuyNet, and any diligence material made available by the County. Offerors are advised to
regularly check BuyNet for information. The County has no obligation to contact Offerors directly with any such RFQ-
related information.
* In order to see all information related to this RFQ, to submit Questions, and to receive notifications of updates,
Offerors must select "Participate in RFx" for this solicitation in BuyNet.
Forms required to be submitted with Offeror's Quotation are included in this RFQ or posted on the County's web site at
https://www.sandiegocounty.gov/content/sdc/purchasing/purchasing-forms.html. Posted forms may be updated from time
to time. Unless otherwise specified, Offerors may submit the version of a form in place as of the date of RFQ issuance or
any later version.
This is a request for information, and quotations furnished are not offers.
QUESTIONS: Please submit questions and requests for clarification related to definition or interpretation of this RFQ in
writing to the contracting officer before the Questions Due date/time listed in this RFQ. Those received after this date may
not be answered at the discretion of the County.
PRICING: The County may award a contract on the basis of initial quotations. Your price(s) should be the lowest possible
for the RFQ requirements. Omit Sales and Use Taxes unless otherwise specified.
The Estimated Quantities in the Pricing Schedule are provided solely for evaluation of quotations. They represent
approximate anticipated use based on historical consumption. If the County's actual requirements do not result in orders in
the quantities described as "estimated" in the Schedule, that fact shall not constitute the basis for price adjustment.
EVALUATION AND AWARD. Quotations are subject to acceptance at any time within 90 days after submission due
date/time, unless otherwise stipulated by the County. This RFQ is an informal negotiated procurement process. Lowest price
may not always be the sole criteria for award of an RFQ. The County reserves the right to waive a variation in specification
if, in the opinion of the County, such variation does not materially change the item or its performance within parameters
acceptable to the County. The County reserves the right to reject any or all quotations and to accept or reject any item(s)
thereon, or waive any informality in the quotation. The County reserves the right to perform a pre-award survey of the
offeror to determine capability to perform, including but not limited to facilities, financial responsibility, materials/supplies,
and past performance. The determination of the County as to an Offeror's prospective ability to perform the contract shall
be conclusive.
SAMPLES: Samples, at Offeror's expense, may be required for evaluation by the County. Delivery of sample must be
scheduled with contracting officer and provided within required timeline. The County shall have the right to review sample
and to determine if such sample is acceptable. The County's decision to award is contingent upon its acceptance of the
products provided in the sample. During the term of the award, the County must approve any substitutions from the initial
sample in writing in advance of substitution. In no event shall the supplier be permitted to increase prices on the basis of
substituted item(s).
Sample, if not destroyed by tests, will, upon request, be returned at Offeror's expense. Offeror must advise contracting
officer at time of sending sample that they must be returned, provide return address and Federal Express account number.
BRAND NAME OR EQUAL: If items called for in this Request for Quotation have been identified in the schedule by a
"brand name or equal" description, such identification is intended to be descriptive, but not restrictive, and is to indicate the
quality and characteristics of products (including products of brand name manufacturer s other than the one described by
Page 3 of 7

COUNTY OF SAN DIEGO
REQUEST FOR QUOTATION (RFQ) 13340 - SUPPRESSORS AND FLASH HIDERS
the brand name) to be considered for award if such products are determined by the County to meet fully the salient
characteristic requirements listed in the request.
Unless the offeror clearly indicates in the quotation that an "or equal" product is being offered, quotation shall be considered
as offering the brand name product specified.
If the offeror proposes to furnish an "equal" product, the brand name, if any, of the product to be furnished shall be inserted
in the space provided in the request for quotation, or such product shall be clearly identified in the quotation. The evaluation
of the quotation and the determination as to equality of the product offered shall be the responsibility of the County and will
be based upon the information furnished by the offeror, or identified in the quotation as well as other information reasonably
available to the purchasing activity. Caution to offerors: the purchasing activity is not responsible for locating or securing
any information which is not identified in the quotation and reasonably available to the purchasing activity. Accordingly,
to insure that sufficient information is available, the offeror must furnish, as part of the quotation, all descriptive material
(such as cuts, illustrations, drawings, or other information) necessary for the purchasing activity to (i) determine whether
the product offered meets the salient characteristic requirements of the request for quotation, and (ii) establish exactly what
the offeror proposes to furnish and what the County is binding itself to purchase by making an award. The information
furnished may include specific references to information previously furnished or to information otherwise available to the
purchasing activity.
If the offeror proposes to modify a product so as to make it conform to the requirements of the Request for Quotation, he
shall (i) include in the quotation a clear description of such modifications and (ii) clearly mark any description to show the
proposed modifications.
DUTY TO INQUIRE: Should the Offeror find discrepancies in or omissions from the RFQ, plans, specifications or other
documents, or should the Offeror be in doubt as to their meaning, the Offeror must at once notify the Buyer, in writing. If
the point in question is not clearly and fully set forth, a written addendum will be issued and emailed to Offerors.
CONFIDENTIAL/PROPRIETARY INFORMATION: If confidential/proprietary is contained within the submission:
1) It must be submitted in a separate file or document marked as EXHIBIT-CONFIDENTIAL/PROPRIETARY;
2) Responses to solicitation requirements that include the confidential/proprietary information, shall refer to the
response contained within the EXHIBIT-CONFIDENTIAL/PROPRIETARY (for example: If submittal
requirement #1 requires staff Social Security Numbers, the response to requirement #1 shall reflect "see response
#1 contained within Exhibit-Confidential/Proprietary"); and
3) It must include a signed Nondisclosure Indemnification Agreement (PC620).
NOTE: As a Public Agency, the County of San Diego must adhere to the California Public Records Act, therefore pricing
cannot be considered confidential/proprietary.

standard Purchase Order (PO) terms and conditions and any additional terms and conditions referenced in this RFQ. The
