Within ten (10) consecutive calendar days after the notice of award, the Consultant to whom a contract is awarded from this request for proposals shall furnish the City, through its third-party insurance partner, Exigis, certificates of insurance and endorsements evidencing coverage as specified in Section VII. Form of Agreement, Section 3.2.10 Insurance, et seq. and naming the City of Corona, its directors, officials, officers, employees, volunteers and agents as additional insureds by written endorsement. Failure to do so may, in the sole discretion of the City, result in the forfeiture of the Contract Award.

Consultants must review, complete and sign the Acknowledgment of Insurance Requirements Check Sheet included in Section V and return with their proposal. Any exceptions or deviations to the City’s insurance requirements must be submitted to the City during the Questions and Answer period. Consultants are cautioned that exceptions or deviations from the RFP insurance requirements may cause their proposal to be rejected as non-responsive.

P. Safety Requirements/Violations

Safety at the Project sites during performance of the work is of paramount concern to the City. Accordingly, consultants must not have committed any serious violations within the last two (2) years or any willful violations within the last five (5) years of federal or state OSHA regulations. Consultants must identify the number of OSHA violations on the CONSULTANT’S SAFETY RECORD form. Any serious or willful violation may render a proposal as non-responsive. We strongly encourage full disclosure since failure to identify all violations on the CONSULTANT’S SAFETY RECORD form may result in rejection of the proposal as non-responsive or the Consultant as non-responsible following a hearing. A citation properly appealed through OSHA is not considered to be a violation until the matter is closed and considered final by OSHA. The City still expects this information to be disclosed by the consultant, with an explanation and documentation showing that the matter is properly under appeal with OSHA and not considered closed or final. Failure to be forthcoming with this information may result in rejection of the proposal as non-responsive.

Q. Payment (Labor and Materials Bond Requirements)

R. Negative History

Consultant must include in its Proposal a complete disclosure of any alleged significant prior or on-going contract failures, any civil or criminal litigation or investigation pending which involves the firm or in which the firm has been judged guilty or liable within the last five (5) years.

If there is no negative history to disclose, the firm must affirmatively state in its Proposal, there is no negative history to report.

Failure to comply with the terms of this provision may disqualify any proposal. The City reserves the right to reject any proposal based upon the firm's prior documented history with the City or with any other party, which documents, without limitation, unsatisfactory performance, adversarial or contentious demeanor, significant failures to meet contract milestones or other contractual failures.

S. Conflict of Interest Statement

The nature of the proposed services for this RFP may lead to a conflict of interest for firms that are currently under contract with the City or those that may seek contract opportunities in the future. The City considers the following situations as potential conflicts of interest that will not be allowed:

The prime consultant or principal partners in a joint venture arrangement for this RFP will be prohibited from competing for future design (defined by the City as Project Approval and Environmental Document (PA&ED) or Plans, Specifications and Estimate (PS&E)) or construction management contracts related to this project.

A sub-consultant that provides more than one-third of the total scope of services (as measured by overall budget) or more than one-third of the full-time equivalent (FTE) for project manager and key positions will be prohibited from competing for future design (PA&ED or PS&E) or construction management contracts.

The prime consultant or principles in a joint venture, or a sub-consultant that provides more than one-third of the total scope of services or more than one-third of the FTEs for project manager or key positions, will be prohibited from competing for future (PA&ED or PS&E) or construction management contracts as a major sub-consultant. City staff will determine the definition of major sub-consultant for future contracts on a case-by-case basis.

The City recognizes that consulting firms that currently hold design contracts may wish to compete as a prime consultant or major sub-consultant for this contract. The City will allow such firms to compete for this contract, however, if successful, those firms will be prohibited from competing for future design or construction management services contracts for this project. Additionally, for firms with existing design contracts, the named principle-in-charge and project manager for those contracts are prohibited from filling key positions in the project management contract.

Consultants shall disclose any financial, business or other relationship with the City that may have an impact upon the outcome of the contract or the construction projects. The Consultant shall also list current clients who may have a financial interest in the outcome of this contract or the construction project that will follow. Consultants shall disclose any financial interest or relationship with any construction company that might submit a bid on any of the listed transportation projects.

T. Public Records

Responses (proposals) to this Request for Proposal (RFP) and the documents constituting any contract entered into thereafter become the exclusive property of the City and shall be subject to the California Public Records Act (Government Code Section 6250 et seq.). The City’s use and disclosure of its records are governed by this Act.

Those elements in each proposal which proposer considers to be trade secrets, as that term is defined in Civil Code Section 3426.1(d), or otherwise exempt by law from disclosure, should be prominently marked as “TRADE SECRET”, “CONFIDENTIAL”, or “PROPRIETARY” by proposer. The City will use its best efforts to inform proposer of any request for disclosure of any such document. The City shall not in any way be liable or responsible for the disclosure of any such records including, without limitation; those so marked if disclosure is deemed to be required by law or by an order of the Court.

In the event of litigation concerning disclosure of information the proposer considers exempt from disclosure, the City will act as a stakeholder only, holding the information until otherwise ordered by a court or other legal process. If the City is required to defend an action arising out of a Public Records Act request for any of the contents of a proposer’s proposal marked “Confidential”, “Proprietary”, or “Trade Secret”, proposer shall defend and indemnify the City from all liability, damages, costs, and expense, including attorneys’ fees, in any action or proceeding arising under the Public Records Act.

To insure confidentiality, proposers are instructed to upload separate files for all “Confidential,” “Proprietary,” or “Trade Secret” data when submitting their proposal documents. The file names shall include the words “Confidential”, “Proprietary” or “Trade Secret". Because the proposal documents are available for review by any person after award of a contract resulting from an RFP, the City shall not in any way be held responsible for disclosure of any “Confidential,” Proprietary,” or “Trade Secret” documents that are not uploaded as separate files and include “Confidential”, “Proprietary” or “Trade Secret" as part of the file name.

Changes in work and the amount of compensation to be paid to the consultant for any extra work as so ordered shall be determined in accordance with the unit prices quoted.

4. Contract Incorporation. This contract embodies the entire contract between the City and the Consultant.

RFP No. 27-006SB Section IV. “Project Description & Scope of Work”

SECTION IV.

PROJECT DESCRIPTION AND SCOPE OF SERVICES

A. PROJECT DESCRIPTION

The City of Corona (City) identified approximately 15,000 linear feet (LF) of water distribution mains in the southeast quadrant of the City’s downtown area that do not meet current City Design Standards (pipe diameters less than 8-inches) and/or have exceeded their useful life expectancy (considering pipe material and age of pipeline). Though no hydraulic concerns were identified in the downtown area (e.g., high velocities, low pressures, inadequate fire flows, and high velocities during fire flows), the City is initiating a waterline replacement project to meet regulatory requirements established by the California State Water Resources Control Board, Division of Drinking Water (DDW). The characteristics and relative locations of these pipelines are listed in Table 1. Existing Segments of Concern and mapped in Figure 1. Existing Segments of Concern (Appendix A).

The City also identified approximately 2,000 LF of segment gaps in the southeast quadrant to increase the looping in the water distribution system to improve system reliability and reduce water age. The relative locations and proposed characteristics of these pipelines are listed in Table 2. Segment Gaps and mapped in Figure 2: Segment Gaps (Appendix B). An exhibit of both the existing segments of concern and the segment gaps mapped in the southeast quadrant of the City’s downtown area is provided as Appendix C.

The City is seeking professional engineering design services to prepare Plans, Specifications, and Estimates for the scope detailed in Section IV. C. In areas where the 8-inch minimum diameters are not feasible due to separation constraints, the Consultant shall provide a hydraulic analysis demonstrating adequacy of supply for the proposed sizing and provide support for the submission of applicable exemption requests to DDW. The Consultant shall complete a Design Technical Memorandum to summarize the results of utility locating efforts, proposed alignments, and areas of proposed exemptions. The Design Technical Memorandum shall also recommend project phasing to ensure minimal water service interruptions. The Design Engineer shall also prepare a pavement restoration plan.
