I. General Specifications

A. The Gwinnett County Department of Transportation (GCDOT) hereby requests Proposals for Consultant Demand Professional Services for the GCDOT. This submission will assist GCDOT in selecting firms to provide demand service support for GCDOT in its implementation of its Special Purpose Local Option Sales Tax (SPLOST) and other capital programs. No minimum or maximum amount of work is guaranteed under this solicitation, and work will be procured on an “as-needed” basis. GCDOT needs sufficient information to determine that your firm is adequately staffed and capable of providing “as-needed” professional services for each of the following service categories for which you may attempt to qualify. Firms must be pre- qualified in the appropriate Georgia Department of Transportation Area-Class for each category sought as below. Firms MUST provide current Georgia Department of Transportation (GDOT) Notice of Professional Consultant Qualification for each category you are proposing with your proposal submittal.

• Service Category A - Pedestrian/Bikeway and Roadway Drainage Improvement Design Services

• Service Category B - Major Roads, Minor Roads, and Intersection Improvement Design Services

• Service Category C - Cost to Cure

• Service Category D - Survey Services

• Service Category E - Traffic Engineering and ITS/ATMS Engineering Design Services

Gwinnett County intends to select a minimum of three (3) firms under each of the Service Categories.

The minimum number noted above is not guaranteed; Gwinnett County reserves the right to award to a smaller or larger number of firms, if in the County’s best interest.

A separate proposal is required for each Service Category from firms if they wish to be considered for that specific Service Category. Consultants shall submit one independent proposal for each Service Category addressing criteria requested under Section C and one independent fee schedule for each Service Category as required under Section D.

The Gwinnett Standard is an expectation of excellence in all that we do. That standard, set over decades, has made Gwinnett a preferred community where everyone can thrive. We make it our mission to deliver superior services that support our vibrantly connected community and as an extension of the County, we expect our business partners to do the same. Beyond just executing the work, we expect our partners to be standard bearers; to act with integrity; to innovate and adapt; to be accountable and transparent; to be fair and respectful to everyone; and to engage, embrace, and unify our community. The successful consultant will incorporate into their response their commitment to upholding and promoting the Gwinnett Standard.

B. Partnering, Teaming, and Sub-Consultants

Partnering, teaming, and sub-consultants will be permitted as part of the proposal but must be clearly identified. Sub-consultants’ resumes and project references should be provided as well as appropriate GDOT prequalification(s).

No work will be paid by GCDOT to any consultant for work done by the consultant or by a sub-consultant if this work is not billed according to the hourly rates and position title submitted as part of their proposal. Subcontractors may be changed later provided they are approved by GCDOT, and the subcontractor is prequalified with GDOT in the appropriate area-class for the work planned and has agreed to the rates set by the prime firm. In addition to the GDOT pre-qualification for the subconsultant, GCDOT will request documentation evidencing both parties’ execution of the agreement and affixing of their respective corporate seals and will retain such documentation on file.

B. Category C – Cost to Cure

The consultant shall provide design services and develop engineering plans, cost estimates, various alternatives and related reports to resolve or provide options to avoid total displacements and to minimize impacts to parcels from right-of-way acquisition for road improvement projects. These design services may ultimately result in permit or construction ready site engineering plans which may involve the relocation or reconfiguration of various site features including signage, parking and access, buildings, stormwater management facilities and utility or septic systems. The consultant should demonstrate a comprehensive knowledge of various jurisdictional zoning and development regulations as well as demonstrate examples of previous permitting of site developments including projects with completed construction.
