}  Counties already utilizing BMS }  Relatively small number of bridges }  Engineers are knowledgeable of their bridges }  Proportionally large variety of bridges }  Analytical methods fail to address local

}  Cost have already increased significantly }  Requires additional training }  Requires additional software Requires additional time

}  Was implemented in the 90’s with no follow thru

}  Is not expected to change the way counties program bridges

}  Do not require LPA’s to implement Element Level Inspection

}  Work with State DOT’s to utilize the extensive data set already collected (via SIIM’s in Iowa) to provide the needed condition assessments of local bridges.
