Specifications include, but are not limited to: The services include preparation of construction contract plans for two bridge replacements within the City of Oregon in Lucas County. The bridges are over Otter Creek on Seaman Road (SFN. 4863127) and on Yarrow Street (SFN 4863143) with a project length of approximately 0.1 mile each. The existing Seaman Bridge is a 26 ft single span structure with reinforced concrete beams and a concrete deck supported by full height concrete abutments walls supported on unknown foundations. The proposed Seaman Road structure will be need to be designed to accommodate both vehicular and pedestrian / bike traffic to include two 12-foot wide lanes, 5-foot paved shoulders and a 5-ft sidewalk along the south side of the structure. The city anticipates that the proposed structure will be an approximately 28 ft span 3-sided structure based on hydraulic information and recent bridge replacement projects for the area. The profile and alignment of the existing roadway is not anticipated to be modified by the project. Some minor shoulder work to the approach roadway may be necessary to accommodate safety grading. The existing Yarrow Bridge is a 29 ft single span structure with reinforced concrete beams and a concrete deck supported by full height concrete abutments walls supported on unknown foundations. The proposed Yarrow Street structure will need to be designed to accommodate two 12-foot wide lanes and 2 ft paved shoulders with a sidewalk along the east side of the structure. The city anticipates that the proposed span will be approximately 28 ft based on hydraulic information for the area and the Taylor Road Bridge (which is just 0.1 miles upstream) that was recently replaced. The following are some of the services that will need to be provided with the design portion of these projects: • Field survey • Location and verification of existing utilities • Hydrologic analysis • Flood hazard analysis including scour analysis • Environmental document preparation (“if authorized” – ODOT to prepare) • Approach roadway design including signage and drainage • Structure design • R/W design and legal description preparation • Maintenance of traffic design • Preparation of final construction plans and specifications
