Tuckahoe State Park is a 3,800-acre stream and valley parkland divided by Tuckahoe Creek in Queen Anne’s and Caroline Counties on Maryland’s Eastern Shore. The project will be a section of the existing Upper/Chesapeake Rail Trail (UCRT) from the end of Cemetery Road to a section across Tuckahoe Creek. The new section of trail will add approximately 1,880-ft to the UCRT. This new section will be an extension to a 2-mile section of trail recently constructed between 2015-2016. The project consists of the upgrade of an existing 1,600-ft gravel path, the rehabilitation of an existing 180-ft long railroad bridge and construction of 100-ft of new trail on an existing abandoned railroad bed.
Brudis & Associates, Inc. (BAI) is providing design and coordination services to prepare construction documents for the trail design, rehabilitation of the railroad bridge, and erosion and sediment control for three design submittals.
BAI is collecting and reviewing any existing project data received from DGS/DNR and prepare field sheets and conduct an initial field review. Additional services include a field survey along the existing railroad alignment and of the existing bridge abutments and piers; developing horizontal alignment, proposed trail geometrics, and proposed shading files showing the proposed UCRT construction; developing a vertical profile for the new section of UCRT, includng across the existing railroad bridge; and develop preliminary cut and fill slope lines using InRoads. BAI is using AASHTO (2012 AASHTO Bicycle Design Guidelines) and ADA (Americans with Disabilities Act) compliance review of the UCRT design (including the bridge) to identify potential issues or waivers. Erosion and Sediment Control drainage map delineations and calculations services are also being provided.
BRIDGE AND RAILROAD STRUCTURE REHABILITATION DESIGN
BAI is performing an in-depth inspection of the existing railroad bridge. The inspection focuses on verifying existing member sizes, measuring areas of corrosion and section loss, documenting missing hardware (anchor bolts, etc.). BAI will utilize rigging provided by rigging vendor for access. Additional services include developing a deck design including railings. Railings will extend to ends of wingwalls.
Developing structure repair details and specifications for replacement of deteriorated anchor bolts, superstructure steel plate or angle repairs and repair of large spalls on abutment/wingwalls. Confirming structural adequacy of the bridge to carry 1) pedestrian loadings and 2) maintenance/construction vehicular loadings (10-ton minimum). BAI is developing a load rating for the deck and girders based on the AASHTO H-15 truck only, no lane load. (The H-15 is similar to flatbed trucks used by contractors and larger than the vehicles used by Park maintenance.)
BAI is also providing general plan and elevation, bridge plan and elevation sheet with general notes, typical section and railing details, bridge typical section and railing details, rehabilitation details, bridge rehabilitation details and notes, erosion and sediment control plans, preliminary cross-section sheets, DD project specifications and construction cost estimate, subconsultant oversight/review/coordination and general coordination meetings.
