Book Description
This research was conducted to (1) analyze an earthmoving productivity, (2) develop detailed schedules for uban interchange reconstruction for the Iowa Department of Transportation (Iowa DOT), and (3) determine whether expediting urban interchange construction is possible solution for shortening duration for the reconstruction of Interstate 235 (I-235). The following projects were used as case studies in this research: (1) interchange reconstruction projects for the 14th Street, 19th Street, and 42nd Street in Des Moines, and 35th Street in West Des moines, (2) bridge demolition projects for the 19th Street, Martin Luther King Street, and 42nd Street in Des Moines in the reconstruction of I-235. The analysis results based on site observation and statistical analysis were described in the case studies. In earthmoving analysis, factors influencing earthmoving production rates, such as bucket capacity, number of passes, and hauling distance in urban interchange construction were significant. For the scheduling part, the as-built schedules for 35th Street in West Des Moines and 42nd Street in Des Moines were developed and compared with contractor's original schedule. The actual urban interchange construction schedule resulted in later completion than originally estimated by contractors. Even if earthwork, utility work, and paving processes were expedited based on the as-built schedules, the activities could be expedited aggresively to reduce the construction duration more. Expedited urban interchange construction is an alternative method to reduce total duration of the I-235 corridor work. Moreover, duration, cost, resource, and sequence for urban bridge demolition were influenced by traffic control and bridge type.
