Franklin County Bridge 105 Deck Rehabilitation January 9, 2026 Page 4 of 8 EXHIBIT 1 SCOPE OF SERVICES In order to meet your needs as outlined in the above paragraph, HRG proposes the following scope of services: PHASE 1 PROJECT MANAGEMENT Task 1 Project Management This task consists of the administrative effort required by HRG to complete the project on time, within budget, and to provide a quality product. Included will be regular in -house meetings of the design staff, coordination with subconsultants if required, coordination and scheduling of project submittals, regular reviews of project costs and progress, preparation and submission of monthly invoices and progress reports, and documentation of meetings, telephone conversations, and design developments. This ta sk will also include the implementation of our routinely practiced quality control measures, use of our formal checking procedures, intermediate plan checks, design review meetings, and Assistant Vice President overview. PHASE 2 FIELD SURVEY AND BASEMAPPING Perform a PA One Call preliminary design web ticket requests for the extents of the Project Limits described below in an attempt to obtain owner/operator contact information, field mark-out and/or record information of public utilities that service the Project Limits. All topographic features will be located and elevated by our survey crew, using a total station system with data collection capabilities, Global Navigation Satellite Systems (GNSS) technology and scanning technology. Topographic features to be surveyed will include top of deck elevations along roadway centerline and gutterlines at tenth points of the bridge, bridge barrier, centerline and edges of the existing roadway, location of existing overhead or above-ground utilities, and existing signs and guide rail. The topographic survey will extend approximately 150 feet along Sylvan Drive, east and west of the bridge center, to the limits of existing guide rail. Transverse limits will extend to the existing guide rail posts to encompass the proposed physical work. It is anticipated that the county or municipalities will provide HRG with the legal right-of-way width and record of legal right-of-way boundaries, if any. All surveys will reference North American Datum of 1983 Pennsylvania State Plane Coordinate System South Zone and North American Vertical Datum of 1988. A survey baseline will be established through the work area, generally paralleling the centerline of the road, with control points established outside the expected area of construction. A minimum of two (2) vertical site benchmarks will be established on a sustainable physical feature, one at each end of the project. This will suffice as control during cons truction. For the purpose of this proposal, HRG assumes all work will be performed within existing legal right-of-way and entrance onto adjacent properties will not be necessary. Deed research and Notice of Intent to Enter (NOITE) letters will not be completed. Franklin County Bridge 105 Deck Rehabilitation January 9, 2026 Page 5 of 8 Basemapping will be developed utilizing Bentley’s Open Road Designer (ORD) at a scale necessary for design and will depict all topographic information obtained via field survey, existing utility information, and existing legal right-of-way. PHASE 3 CONCRETE DECK EVALUATION PennDOT Design Manual, Part 4, Part A: Policies & Procedures Section, Section 5.5.2.3 requires collection of information to determine the type of rehabilitation needed for a deteriorating bridge deck. The following tasks will be completed to meet PennDOT requirements: Task 1 Bridge Deck Assessment HRG will assess the condition of the existing deck using the chain drag method to determine the percentage of delaminated or spalled concrete. A plan sheet will be prepared noting each location with corresponding area, and type of deterioration. Task 2 Bridge Deck Testing HRG will coordinate with ECS Mid-Atlantic, Inc. (ECS) to conduct concrete testing of the existing bridge deck. An HRG engineer will provide on-site supervision of the following tests: ◼ Three concrete deck cores in span 2 ◼ Ground penetrating radar to assess concrete cover over the top mat of rebar ECS will utilize the three (3) concrete deck cores to perform chloride ion concentration, air content , petrographic testing, and a compressive strength test. ECS will provide a summary of the lab testing to HRG for use in evaluating deck rehabilitation methods. Task 1 & Task 2 will be completed on the same day to minimize disruption to local traffic. Traffic control will be provided by County forces. PHASE 4 ENGINEERING Task 1 Roadway Design For the purpose of this proposal, it is assumed the bridge will maintain the existing horizontal alignment and curb-to-curb bridge width. HRG anticipates the overlay will require a minimal raise of the top of bridge deck (less than 2 inches). Roadway design will be limited to setting the horizontal alignment to match existing and establishing a slightly raised vertical alignment at the bridge to accommodate the overlay. It is assumed that the approach roadway will require milling and wearing surface replacement to provide smooth tie-ins. A formal pavement design, full depth reconstruction, guide rail design and guide rail replacement are not included with the scope of work. Franklin County Bridge 105 Deck Rehabilitation January 9, 2026 Page 6 of 8 Task 2 Traffic Control Plan There will be no detour developed for this project. Due to the location of the Road and the typical traffic the County will provide and install Road Closure Signs for the duration required. Task 3 Structure Design This task will consist of an Alternative Analysis and final design of the selected alternative . For concrete deck rehabilitation projects, PennDOT recommends three (3) deck overlay options as options for this project: membrane waterproofing with bituminous overlay, latex modified concrete overlay, and polyester polymer concrete overlay. Alternatives Analysis HRG will prepare an Alternatives Analysis for the deck rehabilitation that will include: ◼ Cost estimate for each option ◼ Advantages and disadvantages of each option ◼ Assessment of deck test results ◼ Rehabilitation recommendation HRG will submit the Alternatives Analysis to the County for review and proceed into final design with the alternative selected by the County. For the purpose of this proposal, HRG assumes one of the three deck overlay options will be selected; however, the deck test results may indicate an overlay is not feasible due to advanced deterioration of the concrete or insufficient reinforcement cover. Should this be the case, the bridge will require a full deck replacement, which is not included in this proposal and will require a substantial supplement for services to include: additional survey, permitting, and additional structure design . Final Design This part is the development of the final structure plans in accordance with PennDOT criteria. PennDOT’s bridge design software will be utilized for final design. HRG will perform the following: ◼ Complete an updated BAR7 load rating analysis, including design calculations. ◼ Develop all required structure drawings including plans, elevations, and details as necessary. Since the scope of roadway work is limited, the structure plans will include the following items typically provided in a Final Construction Plan set: notes, profile, limits of work, and typical section. ◼ Provide pay items and special provisions for the specifications and estimate prepared under Task 4 using historical data for similar projects in the project region. Based on funding for this project, final design calculations and drawings will be submitted to PennDOT for Structural Adequacy Approval. The submission will include PennDOT Form D-4274, Application for Bridge Plan Approval. Franklin County Bridge 105 Deck Rehabilitation January 9, 2026 Page 7 of 8 Task 4 Project Specifications and Cost Estimate Technical specifications will be developed in accordance with PennDOT Publication 408, latest edition. Special provisions will be provided for non-standard items and where needed to modify materials and methods for the various construction items that differ from the PennDOT Publication 408 specifications. The final construction cost estimate will be developed upon the completion of final design activities and based on the final project construction quantities. Unit cost values will be based on best -available sources (e.g., manufacturer information and recent bid results). PHASE 5 BIDDING Task 1 Project Manual A complete bidding package will be prepared for the project. Plans will include a complete set of bridge and roadway construction plans, including “also” plans for the project. A single project manual will be prepared and will include EJCDC contract documents, bid form, and technical specification. Technical specifications will include applicable PennDOT standard special provisions required, as well as project -specific special provisions written to address nonstandard or special requirements. The package will be submitted to the County for review and concurrence. After concurrence, the bid package will be finalized, and the project will be advertised for bid. The County will be responsible for publication and advertising fees. Task 2 Bidding Process Administration Once the County has advertised the project for bid, HRG will provide a means to transmit bid documents electronically or utilize PennBID. During the bidding process, if any bidders submit written questions, HRG will prepare responses to the technical questions and distribute the responses to bidders via an addendum, as deemed appropriate. Bids submitted will be reviewed for completeness and responsiveness with regards to the bidding requirements and will be tabulated according to the bid amount. The County will make the final determination based on HRG’s recommendation as to whether the bid s are acceptable. If so, the County will select the winning bidder. HRG will notify the bidders of the County’s award decision and will assist with awarding a contract. HRG will prepare three (3) copies of the contract documents and forward them to the selected contractor for execution. After execution by the contractor, HRG will review the information submitted to ensure that all requirements of the project manual are met. The information will be forwarded to the County for final review by the solicitor, and subsequent execution by the County. PHASE 6 CONSTRUCTION ADMINISTRATION This task will include coordination and attendance at one (1) preconstruction meeting (at Franklin County Offices) and one (1) final inspection meeting/site visit; review of one (1) change order; interpretation and clarification of the contract documents; review of four (4) contractor applications for payment (anticipated Franklin County Bridge 105 Deck Rehabilitation January 9, 2026 Page 8 of 8 3-month construction schedule with an additional final payment application ); and coordination/attendance of a substantial completion and final completion walk through. This task will include review of the contractor’s shop drawings and material submittals for compliance with the contract documents. Unacceptable submittals will be returned to the contractor for revision, and we will coordinate with the contractor until acceptable submittals are received, up to a maximum of two (2) resubmissions. Approved submittals will be distributed to the contractor after completion of each review. Three (3) submittals are assumed to be submitted by the contractor. PHASE 7 CONSTRUCTION OBSERVATION HRG will perform part-time observation of construction. Site visits to the bridge will occur while key components of work are ongoing, to check contractor’s work for quality and compliance with project plans and specifications. It is anticipated that seven (7) sites visits will be required and on average these visits will last 12 hours (84 manhours total), which will include travel to the site and completion of observation reports.
