Project description

The purpose of this request for proposals (RFP) is to search and report on the available technology and their related costs needed to determine currently missing as-built information for bridges. Examples of pertinent missing information include items that fall under geometry, such as bridge length, width, and other member dimensions, and items related to the strength of the bridge materials, concrete and/or steel, as well as bar locations. Rating strategies will be developed based upon the required parameters for load rating of bridge types, such as concrete precast slab (COPCSS), concrete slab (COSLAB), and concrete pre-stressed channel (COPSCH), and to a lesser extent, pre-stressed girder bridges and steel bridges.
