From page 191... ... NCHRP Project 12-102 A-10 Massena Lateral Slide: • Designer/Owner • Let ABC projects similar to steel bridges (fall letting) • Incentive/Disincentive specification definitions • Precast/CIP option for substructure units • Be prepared to fully evaluate impact of contractor method changes • Elimination of stainless steel sole plate • Rolling in jacking pockets • Do not allow re-use of laminated neoprene bearings • Add a specification requiring falsework design engineer to inspect and accept falsework construction • ABC project design team time • Designer/Owner • Driven pile acceptance criteria need to be modified from the standard specification • More smaller piling is preferred to the fewer larger piling due to pile splice time • More storage space • Separate the falsework bid item from the prefabricated bridge move bid item Kansas Not yet.
