this RFP, or should the prospective offeror find any ambiguity, inconsistency, or

omission therein, the prospective offeror shall make a written request for an official

interpretation or correction by the due date for questions above.

All interpretations, corrections, or additions to this RFP will be made only as an official

addendum that will be posted to a2gov.org and MITN.info and it shall be the

prospective offeror’s responsibility to ensure they have received all addenda before

submitting a proposal. Any addendum issued by the City shall become part of the

RFP, and must be incorporated in the proposal where applicable.

C. PRE-PROPOSAL MEETING

No pre-proposal meeting will be held for this RFP. Please contact staff indicated above

with general questions regarding the RFP.

D. PROPOSAL FORMAT

To be considered, each firm must submit a response to this RFP using the format

provided in Section III. No other distribution of proposals is to be made by the

prospective offeror. An official authorized to bind the offeror to its provisions must

sign the proposal. Each proposal must remain valid for at least ninety days from the

due date of this RFP.

Proposals should be prepared simply and economically providing a straightforward,

concise description of the offeror’s ability to meet the requirements of the RFP. No

erasures are permitted. Mistakes may be crossed out and corrected and must be

initialed in ink by the person signing the proposal.

E. SELECTION CRITERIA

Responses to this RFP will be evaluated using a point system as shown in Section III.

A selection committee comprised primarily of staff from the City will complete the

evaluation. The SEU may, at its sole discretion, make awards by equipment type,

packaged equipment, or bundled offers in the best interest of value to the City and the

VPP Project.

The cost proposals will not be reviewed at the initial evaluation. After initial evaluation,

the City will determine top proposals, and open only those cost proposals. The City

will then determine which, if any, firms will be interviewed. During the interviews, the

selected firms will be given the opportunity to discuss their proposal, specifications,

and their cost proposal in more detail. If the City chooses to interview any offerors,

the interviews will be tentatively held at a reasonable date and time that works for all

parties.

All proposals submitted may be subject to clarifications and further negotiation. All

agreements resulting from negotiations that differ from what is represented within the

RFP or in the proposal response shall be documented and included as part of the final

contract.
