Skipper, PE Project Manager Vice President LLC Scope of Services for Fairchild Road North Dirt Road Paving Okaloosa County, Florida March 6, 2013 Hatch Mott MacDonald (HMM) is pleased to submit our proposal to provide Civil Engineering services for the above referenced project located along Fairchild Road from CR 188 (Airport Road) south to the existing pavement at the entrance to L-3 Crestview Aerospace located in Okaloosa County, Florida. The existing dirt road is approximately 1.82 miles (+/- 9600 LF) in length. It is our understanding that the requested services include data collection, roadway and drainage design, permitting, plans production and bidding assistance with the goal of delivering an estimate of probable cost for construction and a final plan set to pave Fairchild Road from the limits described above. This proposal is based on our understanding of the project, the level of effort required to complete the scope of services defined below, as well as past experience with projects of similar size and scope. Basis for Scope of Services HMM developed this scope of services with the following conditions: e Okaloosa County will advertise this project for contractor bids. e The existing bridge structure and ancillary items (guardrail, rip rap, etc) are excluded from this Scope of Services. TASK 1 - Data Collection HMM shall collect and review available information pertaining to the existing conditions within the defined areas. This shall include, but not be limited to, collecting GIS and existing records from Okaloosa County, performing site reviews, survey of the critical areas, geotechnical exploration and wetland delineations within the included project limits. 1.1 Field Reviews This subtask shall include a thorough review of the project limits and existing features, including all roadway and drainage components, in order to gain a better understanding for development of the project. 1.2 Survey This subtask shall include establishing horizontal and vertical control and a baseline of survey throughout the project limits. These efforts also include collecting limited topographic surveys, which include, but not limited to, above ground facilities, structures, pavements, fences, property markers, existing drainage structures and above ground utilities. Cross sections will also be picked up every 500’ along the roadway and DTM shall be collected through the curves to provide a foundation for setting the geometric controls. This task shall also include surveying wetlands adjacent to the roadway for the purpose of determining any impacts. 1.3 Geotechnical Investigation This subtask shall include performing a geotechnical investigation for the project in order to determine the subsurface conditions along Fairchild Road. This task shall include, but not be limited to, clearing registered utilities at the site before drilling, obtaining an Okaloosa County right- of-way permit, mobilizing and laying out the borings in the field, drilling 20 SPT borings in the existing roadway, performing visual classification of the soil samples, collecting two samples for LBR testing and analyzing the test data to develop the appropriate geotechnical engineering recommendations for the project. 1.4 Wetland Delineation and Permitting This subtask shall include, but not be limited to, a jurisdictional determination of all wetlands regulated under 33 CFR 320-330 (US Army Corps of Engineers in accordance with the Corps of Engineers 1987 wetland delineation manual) and Florida Department of Environmental Protection (FDEP) under Chapter 62-340 F.A.C. These efforts will consist of identification of all wetland resources and review of the land uses and vegetation types, as well as those citing habitat preferences for rare, threatened and species of special concern, and identify any specific areas within the project area that could possibly support listed species. From a State of Florida permitting perspective, it is our understanding that this project should qualify under the Notice General Permit (NGP) 62-330.448 Florida Administrative Code (F.A.C.) to allow the repair, stabilization, or paving of an existing county maintained road and the repair or replacement of bridges that are part of the roadway, within the Northwest Florida Water Management District (NWFWMD). As part of using the NGP, some effective means of stormwater management within the right of way must be incorporated into the project, for instance constructing roadside swales, which can be performed as part of this project. It is our understanding that the activities for this project should qualify under the Nationwide Permit #14 Program in order to comply with the Federal permitting regulations. This program authorizes activities required for the construction, expansion, modification, or improvement of linear transportation projects in waters of the United States. Both the State of Florida NGP and the Federal nationwide permit program authorize up to / acre of non-tidal impacts to regulated wetlands, impacts greater than % acre will require an individual permit and additional permitting fees. TASK 2 - Roadway and Drainage Design After the data collection process is complete, HMM will evaluate the data and begin designing the proposed improvements for Fairchild Road. This will consist of analyzing the existing and proposed cross drains and roadway geometrics, producing roadway plans and preparing design documentation. 2.1 Analyze Existing and Proposed Conditions This subtask shall include analyzing the existing drainage conditions and provide recommendations for improvements within the area. HMM shall delineate the contributing basin for the existing cross drains, excluding the bridge crossing, and calculate the peak runoff rates within each basin. Once the hydraulics are finalized, HMM can proceed with setting the proposed roadway geometrics for the project. This shall include, but not be limited to, establishing a proposed horizontal alignment, vertical grades (where applicable), determining the proposed typical section and calculating a pavement design. 2.2 Plans Production This subtask shall consist of producing construction plans for three phases (30%, 75% and 100% completion) of the project. This includes production for, but not limited to e Key Sheet e Summary of Pay Items Sheet e Typical Section Sheet e Project Layout Sheet e General Notes/Details Sheet Roadway Plan/Profile Sheets Cross Section Sheets SWPPP Sheets Erosion Control Plan Sheets Traffic Control Plan Sheets Utility Adjustment Sheets Signing and Pavement Marking Plan Sheet 2.3 Prepare and Deliver Documentation Report HMM shall prepare a brief report that documents the efforts undertaken during the completion of the above described subtasks. The written report shall include the data gathering efforts, document design criteria and calculations used for establishing the project, any necessary meeting minutes with participants and provide an estimate of probable cost for construction. TASK 3 - Bid Assistance Upon completion of the plans production phase, HMM will assist Okaloosa County with the bidding process. This will consist of holding a pre bid conference, responding to questions from bidders/contractors, creating bid tabulations, analyzing the bids for any inconsistencies and providing any necessary recommendations. 3.1 Pre Bid Conference HMM shall conduct a pre-bid conference for construction and permitting. This includes gathering and responding to questions from proposed bidders, providing meeting minutes that formally documents the efforts undertaken during the completion of the above described subtasks. 3.2 Bid Tabulation This subtask shall include performing a bid review and investigating the proposed bidders’ references, along with creating a bid tabulation form and a summary of all received bids. HMM shall also analyze the bid tabulation sheet, checking for inconsistencies, prepare any necessary recommendations and attend scheduled BOCC meeting as required. Total Fee (Not to Exceed) for Tasks 1-3 - $77,822.00 This subtask shall List of Deliverables: e 2 Hard Copies of the 30%, 75% and 100% Plan Sets e 1 Hard Copy of the Design Documentation Report ° 1 Electronic Copies (CD) for each Phase submittal Upon completion of the 30% submittal and the data collection phase, HMM shall determine and evaluate any additional right-of-way needs and/or wetland impacts. Once the evaluation is completed and HMM determines the need to incorporate any findings that would impact the existing scope of services, Okaloosa County would be notified to further discuss the results. These additional services are not included in the current scope of services and shall include, but not be limited to, providing legal sketches and descriptions for additional right-of-way needs, preparing written narrative descriptions of the findings to be used in the necessary individual permits for both State and Federal regulatory agencies for wetland resource permits. Exhibit A Conceptual Plan and Notes for Scope of Services — Fairchild Road
