Justification Item #B-122—Architectural Railing Systems-HSS Support for Guard Railing System Modifications. This new item is being added to account for all field and fabrication shop costs associated with modifying the architectural railing systems on the bridge. Following the concrete placement for the bridge decks, the steel stringers supporting the concrete decks deflected more than anticipated. Since the railing frames were already designed and fabricated, the straight frames needed to be modified to fit the final curved surface caused by the additional deflection. This modification work required transporting material to the contractor's fabrication shop, cutting frame material, redesigning the railing support system to fit, new layout of railing support system, acquiring new materials, welding materials, and transporting modified railing support system to the jobsite and installing the modified railing support system. This additional work required 27.5 working days. Item #B-123—Bridge Lighting Router/Antenna Modifications. This new item is being created to account for costs for a new antenna, and to relocate the router and antenna for the bridge lighting in a location that allows the signal to reach all areas of the bridge, so that all of the color lighting may be used to illuminate the lower parts of the bridge. These modifications will enable the colored bridge lighting to work throughout the entire length of the bridge.
