Specifications include, but are not limited to: The Town of Dover is looking to completely replace the decking on the bridge with modifications made to ensure easier maintenance and future replacement. Currently the decking is made up of 70.5 13’x12”x6” wooden beams. The beams are secured to the bridge using anywhere from 13 to 15 3/4” bolts each through the beams from the top to plates and nuts underneath securing to the metal trusses to the underside of the Bridge. There are also beams running on top of the current decking on either side of the bridge to fill the space between the decking and trusses which will need to be replaced as well. (See appendix A for photos) The desired replacement includes new base decking material (beam or otherwise) to replace the current sub decking on the bridge running across the bridge deck (horizontally). Additionally, a second thinner layer to be run with the travel direction of bridge (vertically) is desired to be easily removed and replaced as needed due to wear and tear from usage, maintenance and plowing. The final height of the decking must match the current height to ensure that it does not become a fall hazard and will not cause unneeded damage to our maintenance vehicles.
