Insurance Requirements of this agreement. Insurance requirements are non-negotiable.

2.15. Certificates of Insurance

Upon notification of a recommended award, the Offeror will have 14 calendar days to submit a complete certificate of insurance in the minimum amounts and the coverages as required in the

Unless otherwise indicated, award(s) will be made to the most responsive, responsible

Offeror(s) who are regularly established in the service, or providing the goods, contained in this solicitation and who have demonstrated the ability to perform in an acceptable manner.

A. Factors that may be considered by the City include:

1. Technical capability of the Offeror to accomplish the scope of work required in the

Solicitation. This may include performance history on past and current government or industrial contracts; and,

2. Demonstrated availability of the necessary manpower (both supervisory and operational personnel) and necessary equipment to accomplish the scope of work in the Solicitation; and,

B. Notwithstanding any other provision of this solicitation, the City reserves the right to: (1) waive any immaterial defect or informality; or (2) reject any or all offers or portions thereof; or (3) reissue a solicitation.

C. A response to a solicitation is an offer to contract with the City based upon the terms, conditions, and specifications contained in the City’s solicitation. Offers do not become contracts until they are executed by the Chief Procurement Officer or Department

Director. A contract has its inception in the award, eliminating a formal signing of a separate contract. For that reason, all of the terms, conditions and specifications of the procurement contract are contained in the solicitation, and in any addendum or contract amendment.

2.17. Solicitation Transparency Policy

Commencing on the date and time a solicitation is published, potential or actual Offerors or respondents (including their representatives) shall only discuss matters associated with the solicitation with the Mayor, any members of City Council, the City Manager, any Deputy City

Manager, or any department director directly associated with the solicitation (including in each case their assigned staff, except for the designated Procurement Officer) at a public meeting, posted under Arizona Statutes, until the resulting contract(s) are awarded to all offers or responses are rejected and the solicitation is cancelled without any announcement by the

Procurement Officer of the City’s intent to reissue the same or similar solicitation.

As long as the solicitation is not discussed, Offerors may continue to conduct business with the

City and discuss business that is unrelated to the solicitation with the City staff. Offerors may not discuss the solicitation with any City employees or evaluation panel members.

Offerors may discuss their proposal or the solicitation with the Mayor or one or more members of the Phoenix City Council, provided such meetings are scheduled through the Procurement

Officer, and are posted as open meetings with the City Clerk at least 24 hours prior to the scheduled meetings. The City Clerk will be responsible for posting the meetings. The posted notice shall identify the participants and the subject matter, as well as invite the public to participate.

With respect to the selection of the successful Offerors, the City Manager and/or City Manager's

Office will continue the past practice of exerting no undue influence on the process. In all solicitations of bids and proposals, any direction on the selection from the City Manager and/or

City Manager's Office and Department Head (or representative) to the proposal review panel or selecting authority must be provided in writing to all prospective Offerors.

This policy is intended to create a level playing field for all Offerors, assure that contracts are awarded in public, and protect the integrity of the selection process. OFFERORS THAT

VIOLATE THIS POLICY SHALL BE DISQUALIFIED. After official Notice is received by the City for disqualification, the Offeror may follow the Protest process, unless the Solicitation is cancelled without notice of intent to re-issue.

“To discuss” means any contact by the Offeror, regardless of whether the City responds to the contact. Offerors that violate this policy will be disqualified until the resulting contract(s) are awarded, or all offers or responses are rejected and the solicitation is cancelled without any announcement by the Procurement Officer of the City’s intent to reissue the same or a similar solicitation. The City interprets the policy as continuing through a cancellation of a solicitation until Council award of the contract, as long as the City cancels with a statement that the City will rebid the solicitation.

2.18. Protest Process

Offeror may protest the contents of a solicitation no later than seven days before the solicitation deadline when the protest is based on an apparent alleged mistake, impropriety or defect in the solicitation. Protests filed regarding the solicitation may be addressed by an amendment to the solicitation or denied by the City. If denied, the opening and award will proceed unless the City determines that it is in the City’s best interests to set new deadlines, amend the solicitation, cancel or re-bid.

Therefore, unless otherwise notified by a formal amendment, the Protester must adhere to all solicitation dates and deadlines, including timely filing of an offer, regardless of filing a protest.

Offeror may protest an adverse determination issued by the City regarding responsibility and responsiveness, within seven days of the date the Offeror was notified of the adverse determination.

Offeror may protest an award recommendation if the Offeror can establish that it had a substantial chance of being awarded the contract and will be harmed by the recommended award. The City will post recommendations on the City’s Procurement Portal to award the contract(s) to an Offeror(s). Offeror must submit award protests within seven days after the posting of the award recommendation, with exceptions only for good cause shown, within the

City’s full and final discretion.

All protests will be in writing, filed with the Procurement Officer identified in the solicitation and include the following:

• Identification of the solicitation number;

• The name, address and telephone number of the protester;

• A detailed statement describing the legal and factual grounds for the protest, including copies of relevant documents;

• The form of relief requested; and

• The signature of the protester or its authorized representative.

The Procurement Officer will render a written decision within a reasonable period after the protest is filed. The City will not request City Council authorization to award the contract until the protest process is complete. All protests and appeals must be submitted in accordance with the

City’s Procurement Code, (Phoenix City Code, Ch. 43) and any protests or appeals not submitted within the time requirements will not be considered. Protests must be filed with the

Procurement Officer.

2.19. Public Record

All Offers submitted in response to this solicitation will become the property of the City and become a matter of public record available for review pursuant to Arizona State law. If an

Offeror believes that a specific section of its Offer response is confidential, the Offeror will isolate the pages marked confidential in a specific and clearly labeled section of its Offer response. An Offeror may request specific information contained within its Offer is treated by the

Procurement Officer as confidential provided the Offeror clearly labels the information

“confidential.” To the extent necessary for the evaluation process, information marked as

“confidential” will not be treated as confidential. Once the procurement file becomes available for public inspection, the Procurement Officer will not make any information identified by the

Offerors as “confidential” available to the public unless necessary to support the evaluation process or if specifically requested in accordance with applicable public records law. When a public records request for such information is received, the Procurement Officer will notify the

Offeror in writing of any request to view any portion of its Offer marked “confidential.” The

Offeror will have the time set forth in the notice to obtain a court order enjoining such disclosure.

If the Offeror does not provide the Procurement Officer with a court order enjoining release of the information during the designated time, the Procurement Officer will make the information requested available for inspection.

2.20. Right to Disqualify

The City reserves the right to disqualify any Offeror who fails to provide information or data requested or who provides materially inaccurate or misleading information or data. The City further reserves the right to disqualify any Offeror on the basis of any real or apparent conflict of interest that is disclosed by the Offer submitted or any other data or information available to the

City. This disqualification is at the sole discretion of the City. By submission of a solicitation response, the Offeror waives any right to object now or at any future time, before any agency or body including, but not limited to, the City Council of the City or any court as to the exercise by the City of such right to disqualify or as to any disqualification by reason of real or apparent conflict of interest determined by the City. The City reserves the right to replace the disqualified

Offeror.

2.21. Contract Award

The City reserves the right to award a contract by individual line items, by group, all or none, or any other combination most advantageous to the City. The City reserves the right to award multiple contracts.

2.22. Determining Responsiveness and Responsibility

Offers will be reviewed for documentation of any required minimum qualifications, and completeness and compliance with the solicitation requirements. The City reserves sole discretion to determine responsiveness and responsibility.

Responsiveness: Nonresponsive Offers will not be considered in the evaluation process. The solicitation states criteria that determine responsiveness, and the solicitation includes terms and conditions that if included or excluded from Offers will render an Offer nonresponsive.

Responsibility: To obtain true economy, the City must conduct solicitations to minimize the possibility of a subsequent default by the Offeror, late deliveries, or other unsatisfactory performance that may result in additional administrative costs.

3.5. Definitions, Standards, and Acronyms

City: The City of Phoenix

Geocomposite: A drainage layer (geonet/mesh like) located between two pieces of Geotextile.

The Geotextile is used to filter out small particulates from getting into the drainage layer or the leachate pipes.

Geomembrane: Double-sided textured (60 mil) high density polyethylene (HDPE)

Geomembrane with roughened, high friction surfaces created by co-extrusion, impingement, lamination, or other approved methods to create double-sided texturing. The cell will use textured liner on the floor and slopes. The stipples or roughness increases the friction between the layers and protects the whole liner from slipping down the slope when the garbage is placed.

Geosynthetic Clay Liner (GCL): A layer of sodium bentonite between a woven and non-woven geotextile layer. GCL helps seal around penetrations, self-heal punctures, and self-seam at the overlaps.

Geosynthetics: Refers to all landfill liners including Geocomposite, Geomembrane, Geosynthetic Clay Liner, and Geotextile.

Geotextile: A permeable textile liner used to increase soil stability, provide erosion control or aid in drainage. Geotextiles are either needle punched (non-woven) or woven. The needle punch product is fluffy and thicker and provides good filtering. The woven is thinner and shiny. It is also used for filtering and protecting other system components. Geotextiles are only used within the leachate trenches.

HDPE: High Density Polyethylene

MARV: Minimum Average Roll Values
