We understand that the project consists of the following: General The project generally consists of the development of an 8-ft wide , asphalt multi-use trail and expansion/retrofit of an existing concrete sidewalk along the north side of the US Hwy 80 Corridor on Tybee Island . The project begins at Byers st. and heads west approximately 5850-ft. The majority of the proposed trail is to be located on the historic Marsh Hen railroad bed. The proposed trail will provide pedestrian/bicycle connectivity from Battery Park to the existing termination of the City of Tybee Island's (the City) designated bicycle path , RV park and public parks. The project is funded with a Transportation Enhancement (TE) Grant and City matching funds; therefore , the project shall be designed, permitted and constructed in accordance with the requirements set forth by the TE Grant and by Georgia Department of Transportation (GDOT) standard specifications. Currently GDOT has contracted Moreland Altobelli (MA) to review and approve all TE documents for conformance with TE and GDOT requirements prior to GDOT approval. To help ensure the project is within budget, the design plans will be developed with a base bid and an add alternate that may be considered for construction depending on the received bids. The base bid is proposed to include the proposed trail route from Byers st. to Battery Park, approximately 3750-ft. The add alternative will extend the project further to the west along the Marsh Hen railroad bed an additional 21 OO-ft. Concept Validation / Concept Report Phase The first step in the project will be to evaluate the current proposed concept route/scope limits to determine if the limits are still appropriate and can be constructed within the ___ Owner's Initials /:7)[' Consultant's Initials CHARLESTON, SC I MYRTLE BEACH, SC I WILMINGTON, NC I BRUNSWICK , GA Ms. Oiane Schleicher City of Tybee Island Letter Agreement for Services April 3, 2012 Page 2 project budget. As this project is located along a state route, a mandatory Concept Team Meeting is required. We will hold a Concept Team Meeting with City, GOOT and MA representatives to review the preliminary project concept and determine any special requirements or changes that may need to be considered. Once the preliminary concept is developed , a field review with the City representatives will be completed to verify preliminary concept. Additional information obtained during the field reviews will be reviewed with the City and based on comments a final updated conceptual drawing will be prepared. Any changes or alternates to the preliminary concept plan derived from the field review will be addressed and reflected within the Concept Report documents and exhibits that will be prepared and submitted to MA and GOOT. A conceptual cost estimate will be required as part of the Concept Report submittal and therefore, will be prepared and submitted to MA and GOOT for the proposed trail and associated improvements . Environmental/ Special Studies Upon GOOT approval of the concept report, we will begin the Categorical Exclusion (CE) process for the project. The special studies required by GOOT for approval of the CE will be completed and submitted for review and approval. Comments from GOOT will be addressed twice per study as part of this scope; additional comments will be handled as an additional service. The required special studies and their description are listed below: • Air Quality Assessment -FHWA and GOOT require an air quality evaluation for completion of the CE document. Based on the proposed improvements an air quality assessment indicating no impacts is anticipated for this project. The document stating as such will be prepared and submitted to MA for review and approval prior to submittal to GOOT and FHWA for approval. Since this is a trail project, the scope does not include any air quality modeling. Should modeling be required for approval of the air quality assessment, it will be handled as an additional service . • Noise Assessment -GOOT requires a noise assessment for completion of the CE document. Based on the proposed improvements, it is anticipated that there will be no adverse impacts due to this project. A noise impact assessment stating as such will be prepared and submitted to MA for review and approval prior to submittal to GOOT and FHWA for approval. Since this is a trail project, the scope does not include any noise modeling. Should modeling be required for approval of the noise assessment, it will be handled as an additional service. • Environmental UST / Hazardous Waste Assessment -It is n ot anticipated that any Environmental UST / Hazardous Waste sites are within the project corridor. The CE document will be prepared based on this assumption. Should it be determined there are environmental UST / hazardous waste sites are within the project corridor the appropriate reports will be handled as an additional service. • History and Archaeology Report - A report investigating the presence of historical or archaeological sites and/or artifacts is required for the CE document. This report will be reviewed by FHWA, SHPO and GOOT for approval. Based on the information contained within the City's request for qualifications, it appears that there are historical or archaeological sites within this project's corridor. Upon ___ Owner's Initials ~("Consultant's Initials Ms. Diane Schleicher City of Tybee Island Letter Agreement for Services April 3, 2012 Page 3 completion of the archival research, the completed Section 106 worksheet will be submitted to MA for review and approval prior to submittal to GDOT, SHPO and FHWA for approval. If field reconnaissance and/or a full archaeology findings report in accordance with a Phase 1 survey will be required for the approval of the history and archaeology reports it will be completed as an additional service . • Wetland Delineation and Verification -All waters of the state (previously delineated and new) will be delineated and verified by the U.S. Army corps of Engineers (USACE) . A jurisdictional determination request will be submitted to USACE for verification. The approved jurisdictional determination will be used to determine any required buffers and/or buffer impacts. It is anticipated that there will be buffer impacts but that there will not be any wetland/marsh impacts. The cost associated with the permitting of the buffer impacts has been included . • Threatened & Endangered Species Survey -This document is required for completion of the CE document and shall include the review of information regarding known occurrences of state and federally protected species, a survey of the project corridor to determine presence and/or absence of species listed within Chatham County and preparation of the necessary report for submittal to the reviewing agencies. • Ecology Report Preparation -This document is required for completion of the CE document. Upon completion of all necessary field work, an ecology report will be prepared in accordance with the GDOT Environmental Procedures Manual. The report will include a description of jurisdictional water, threatened and endangered species, essential fish habitat, invasive species, etc. as required by GDOT. This report will be submitted to for review and approval by MA and GDOT. This section of Tybee Island has known historical, archaeological and ecological resources and at this time there are no anticipated impacts to any such resources . If during the project any work in addition to that which is described in this proposal is required, it will be handled as an additional service. Database Preparation Based on the indicated project corridor, Thomas & Hutton will perform survey services along the proposed route of the pathway. The length of the survey will be approximately 5850-ft feet beginning at Byers St . and heading west along the road shoulder and the Marsh Hen railroad bed. The survey corridor will include the railroad bed and approximately 10' beyond the toe of slope and from the centerline of the road to a distance 10' into the marsh for the portion of the proposed trail immediately adjacent to the road. It will consist of a topographic and wetland survey along the entire project corridor. The survey of the route will be completed using a combination of conventional survey equipment and Global Positioning System (GPS) technology. All wetlands and waters of the state will be located based off of flags placed in the field to demark such features . Existing property surveys along the route will be established using existing right­ of-way plans, courthouse records, and monumentation located in the field during the topographic survey. The topographic survey will include location of buildings, road, sidewalks, drainage structures and surface appurtenances of underground utilities (i.e . water, gas, power, fiber optic, cable and telephone) within the project limits. Horizontal ___ Owner's Initials O K Consultant's Initials Ms. Diane Schleicher City of Tybee Island Letter Agreement for Services April 3, 2012 Page 4 and Vertical datum for the survey will be the Georgia State Plane Grid, East Zone NAD83 (1994) and NAVD88, respectively. The base mapping will be provided to the City for review and comment once the work has been completed. While at this time it is our understanding that the City or GDOT owns all the property located within the project corridor, should areas of concern arise during the survey process, we will notify GDOT and the City of potential right of way needs. At this time it is not anticipated that any easements or right of way will be required for this project and therefore boundary surveys and easement plat preparation for individual parcels is not included in this scope of work. Survey deliverable will consist of an Autocad base file showing existing road rights­ of-way and topographic and wetland information. A computerized digital terrain model will be developed using AutoCAD design software. Geotechnical Soil Survey and Pavement Recommendations It is not anticipated that a Geotechnical report will be required for approval. No cost associated with this has been included in this proposal. Design Based on the approved Concept Report, recommendations set forth in the environmental green sheet and database, the project will be designed as directed by the City using AASHTO guidelines and GDOT design standards for trails and pathways. It is anticipated that the trail will be constructed of asphalt for the new location and concrete for the retrofitting of the existing concrete sidewalk. The plans are anticipated to consist of grading, drainage, signing, marking, erosion control, profiles, cross sections, structures (as defined herein) and details as coordinated with the City. They will be set up to include a base bid from Byers St. to Battery Park (approx. 3750-ft) and an add alternate to extend to the west an additional 2100-ft along the Marsh Hen railroad bed. The construction drawings will be presented to the City and GDOT for review and comment at the preliminary and final levels respectively. This project will be completed in a single phase and one set of construction plans will be prepared for the project. An engineer's opinions of cost will be provided with each submittal. Comments will be addressed once for each of the submittals. Any comments addressed beyond this will be billed as an additional service. Utilities along the route will be contacted and their location and interferences will be coordinated as they are identified. We will coordinate with Georgia Power for their participation in the design and funding of the heavier duty asphalt section paralleling the existing power lines. Design for relocation of existing utilities is not anticipated and therefore is not a part of the scope for this project. The technical specifications for the project shall be the current GDOT standard specifications and any required special provisions. Lighting and landscaping services are not anticipated at this time and therefore are not included in this scope. Assistance in preparing the appropriate utility coordination letters, ADA letters, Property Agreements and Right of Way Certifications to meet the guidelines for the TE grant will be completed during the design phase. This scope includes two meetings with the City during the design process, once during preliminary plan phase and once during final plan phase. Assistance During Bidding The Engineer will assist the City during the bidding process of the project. The Engineer will prepare the bid form and a project description for use by the City in advertising and bidding the project. The Engineer will attend the pre-bid conference and assist the City in answering technical questions related to the plans. The Engineer will then review the ___ Owner's Initials r:::::7L consultant's Initials Ms. Diane Schleicher City of Tybee Island Letter Agreement for Services April 3, 2012 Page 5 bids for the project and provide a recommendation to the City regarding award of the project. Construction Services Based on the TE agreement it is the local sponsor's responsibility for construction observation and monitoring . Once the project has been awarded, we will assist the City during the construction phase of the project. We will attend the pre-construction conference for the project and review the shop drawings and monthly pay request for the project and recommend approval of these items by the City. These construction phase services are not resident construction phase services. The Engineer will make periodic site visits during the course of the construction to determine if the construction is progressing in a manner consistent with the plans and specifications for the project. In order to establish a budget for the construction phase services it was assumed the construction time for the project would be approximately 12 weeks and that the project field representative would spend on average 3 hours per week on the job site. If more time is needed, the Engineer will notify the owner and additional funds will need to be authorized by the owner to continue the construction phase services. Once construction has been completed, a final project site visit will be made and a recommendation on final payment will be sent to the City. Record drawings for the pathway will be compiled based on information supplied by the Contractor and Construction Personnel. No field surveys will be provided as a part of the record drawings but can be completed as an additional service if requested by the City. The required water quality monitoring to comply with the National Pollutant Discharge Elimination System (f\IPDES) will be performed by the contractor and will be included in the contractor's bid. We propose that payment for our services will be as follows: Fee or Time & Phase Fee Structure Expense Budget Concept Development Time & Expense -Budget $ 5,600.00 Environmental Time & Expense -Budget $ 21,000.00 Database Preparation Time & Expense -Budget $ 12,700.00 Design Time & Expense -Budget $ 33,300.00 Bid Assistance Time & Expense -Budget $ 3,000.00 Construction Observation Time & Expense -Budget $ 10,900.00 The above fee arrangements are on the basis of prompt payment of our invoices and the orderly and continuous progress of the Project through construction.
