• Abstract:
  This study developed Daily Work Report (DWR) based prediction models to determine reasonable
  
  production rates of controlling activities of highway projects. The study used available resources such as
  
  DWR, soil data, AADT and other existing project data from the various divisions of ODOT as primary
  
  source in estimating productivity. The study describes the effects and variations of production rates of
  
  highway activities to changes in environmental, geographical and project site conditions. The study also
  
  includes a relative comparison between a survey of experts’ estimate of production rate and DWR based
  
  prediction models. An Excel based standalone software program developed for ODOT engineers and
  
  schedulers to estimate reasonably accurate production rates is also presented in the study.
  
  The output of this model would allow ODOT engineers and schedulers to improve their accuracy and
  
  save their time in determining more reliable production rates of major highway construction activities by
  
  easily adjusting site conditions and project factors. The program will help ODOT to determine
  
  appropriate contract times of Tier II highway projects which would enhance better planning of resources,
  
  reduce construction cost, minimize the construction crew’s exposure to traffic, reduce the inconvenience
  
  to the public, track project progress and future estimating and bidding guidelines. This study will not only
  
  allow ODOT to be equipped with a streamlined procedure for determining production rates of highway
  
  construction activities, but will also be a framework and a benchmarking example to other highway
  
  agencies.
