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.
