Veteran- -Disabled Veteran Owned small business, -Owned small business, etc. ADDITIONAL PROJECT DESCRIPTIONS: The following description is a hypothetical project for a hypothetical railroad bridge located in the Bay Area. The bridge is no longer used for rail traffic and one side of access has had the rail removed. It consists of a vertical lift steel bridge center section between two steel support towers. The center section span is approximately 214 feet (ft) and estimated weight of approximately 300 tons. The lift span is still in use to provide clearance for marine traffic. The bridge spans a narrow tidal canal with a depth of approximately -30 ft Mean Lower Low Water (MLLW). The towers provide a maximum vertical clearance of 135 ft above Mean Higher High Water (MHHW) with the lift span fully raised, and a minimum clearance of 13 ft above MHHW. The bridge is a single-track, steel truss, vertical lift bridge with single span, ballasted deck concrete approaches. The lift span deck uses wood ties on steel beams. It was designed in 1949 by Woodruff and Sampson Engineers and constructed in 1950 and 1951. It was designed to carry a Cooper E-50 live load. The 214 ft long lift span has through trusses centered at 18 ft. The lift span is raised using wire ropes that rap around sheaves at the top of the towers. A counterweight in each tower is attached to the wire ropes supporting the lift span to reduce the force required to move the span. The structure is constructed of steel, except for the approaches and foundation, with members consisting of rolled shapes as well as built-up members and lattice type members. The towers are 185 ft tall each with an estimated total weight of between 230 tons to 300 tons. Including the approach spans the bridge has an overall length of 377 ft. The towers are supported on concrete piers which rest on concrete filled cofferdams. The piers consist of concrete stem wall columns, connected by a concrete beam at the bottom of the walls, and constructed upon a mass concrete sub-footing encased in sheet piling. Immediately adjacent to the railroad bridge is a 4-lane bascule vehicle bridge. The vehicle bridge top of deck elevation is approximately 27 ft MLLW and has no overhead obstructions. There is approximately a distance of 35 ft between the two bridges. The bridge operator house is next to one of the railroad bridge towers and on the same concrete pier. It is used to operate both bridges. A recycling center is located approximately 4 miles away that can be accessed by canal, rail, or highway. Access to the tracks would require traveling approximately 0.5 miles by roadway. Railroad Bridge Removal In this hypothetical project the railroad bridge will be removed, and two options of disposal will be considered (transport or disposal). This would include removing the towers, bridge span, the pier that does not have the operators house, the abutments, and approaches. The pier being removed will be to at least the existing mud line. Options for crane setup location include but are not limited to canal and railroad bridge approaches. It is undetermined if one or both portions of each railroad bridge approach may be used for access and staging. It is undetermined if bubble curtains, coffer dams, or a fish window will be required for the removal of the railroad bridge. Removal and Transfer This option would be the removal of the bridge components described above. The center bridge span and each individual tower would be removed for transport. These components of the bridge would need to be removed and transported in a manner that would allow for reassembly and reuse. The distance of transport could be the length of the canal and across the bay. All other components of the bridge described above would be disposed of or recycled and transported by any means. Transportation may be under a separate contract with a non-Corps entity. Removal and Disposal This option would also be the removal of the bridge components described above. All components could be removed by what is deemed as the most appropriate size by the contractor and all materials would be recycled or disposed of. The estimated price range for this project is $5 - $10 MILLION CAPABILITIES/ QUALIFICATIONS and Proposed methodology: 1. Describe your method for crane setup of the railroad bridge removal. 2. Describe your method for removal of the towers and lift span. 3. Describe your method for taking the towers down from the canal. 4. Describe your method for transporting the concrete rubble. 5. Describe your method of transport of steel from the towers and lift span to the recycling center. 6. Describe your method of removal of concrete abutment and approach above the water line. 7. Describe your process for under water removal of concrete. 8.
