INTRODUCTION

As requested by the Transportation Management Services Division (hereinafter, the “Division or Department”), the Collier County Board of County Commissioners Procurement Services Division (hereinafter, “County”) has issued this Request for Professional Services (hereinafter, “RPS”) with the intent of obtaining proposals from interested and qualified Proposers in accordance with the terms, conditions and specifications stated herein, in the Solicitation and/or attachments. The Proposers, at a minimum, must achieve the requirements of the Specifications, Scope of Services or Scope of Work stated. All references to “Proposer” are also referred to as “Consultant,” “Firm,” “Offeror,” “Contractor,” and “Vendor.”

The County intends to award a single contract to a qualified Consultant to provide professional engineering services for the Lake Park Boulevard Area Improvements and Flow Way Restoration Project. The County previously commissioned the 2023 Lake Park Boulevard Area Improvements & Flow Way Restoration Pre-Design Study (see Exhibit O). the selected Consultant shall independently evaluate existing conditions, available data, the Pre-Design Study, and other County furnished information and shall be responsible for developing and supporting its own engineering analyses, recommendations, and final design. The selected Consultant shall not be required to adopt the conclusions, assumptions, methodologies, alternatives, or recommendations contained in the Pre-Design Study.

Services are anticipated to include independent review and evaluation of the Pre-Design Study, and available project information, surveying and subsurface utility investigation, engineering analysis and design, environmental and regulatory permitting, preparation of construction plans and specifications, engineer's cost estimates, bidding assistance, construction administration, post-design services through project completion, and consultation services during the construction warranty period. Historical expenditures for similar neighborhood-scale drainage projects vary based on final scope; however, historical spending may not be indicative of future buying patterns.

BACKGROUND

The Lake Park neighborhood, located south of US-41 in Collier County, experiences recurring flooding due to aging and underperforming stormwater infrastructure, limited conveyance capacity, and hydraulic constraints within the existing drainage system. These conditions have resulted in periodic flooding of roadways and residential properties during significant rainfall events. To evaluate potential solutions, the County commissioned the 2023 Lake Park https://procurement.opengov.com/portal/collier-county-fl

Boulevard Area Improvements & Flow Way Restoration Pre-Design Study. The study assessed increasingly complex scenarios for stormwater and infrastructure improvements, including the addition and upsizing of stormwater conveyance pipes, installation of water control structures, wetland restoration and enhancement, roadway elevation modifications, roadway widening, and sidewalk improvements.

The study evaluated alternatives intended to improve stormwater conveyance, reduce flooding, enhance water quality, restore hydraulic connectivity, and improve the overall resiliency of the drainage system within the project area. Based on the findings of the study, conceptual recommendations were developed for future implementation. The County now seeks professional engineering services to advance the project through engineering design, permitting and construction. The selected Consultant shall independently evaluate the recommendations of the Pre-Design Study, available project information, and existing conditions and shall be responsible for developing and supporting its own engineering analyses, recommendations and design and prepare the engineering, permitting, and construction documents necessary to implement the improvements ultimately approved by the County.

Minimum Qualifications for Consultant

A professional engineering firm with demonstrated expertise in stormwater hydrology and hydraulics modeling and design, facilitating successful agency permitting and construction with minimal amendments. Experience includes designing stormwater retrofit solutions for existing neighborhoods, conducting professional surveying and easement documentation, road reconstruction, resolving utility conflicts, designing retaining walls, and performing environmental impact assessments and permitting. Please provide at least three (3) references from the past six (6) years; additional references and copies of licensing are welcome to showcase expertise across all relevant areas.

The County’s Selection Committee will evaluate proposer qualifications consistent with the Evaluation Criteria and the requirements outlined in this Scope of Services.

AWARD AND TERM OF AGREEMENT

The County reserves the right to modify this scope during negotiations for budgetary reasons.

The agreement term, if an award is made, is intended to commence on the date of the Notice to Proceed and end upon acceptance and approval of final payment.

Prices shall remain firm for the term of the awarded contract. Surcharges will not be accepted in conjunction with this award; such charges should be incorporated into the pricing structure.

DETAILED SCOPE OF WORK
