Abstract:
|
Many highway agencies face the problem of contract time delays in transportation construction projects. Such delays can have adverse effects on the owner, contractor and the facility users. Time delay may be caused by any party to the contract; its causes may include changes in engineering design and the factors of production, and certain characteristics of the contract bidding process and project environment. Focusing on the latter, in this study a methodology is developed to investigate the likelihood and extent of time delay in highway construction projects. Logit and hazard-based duration models are estimated using data from a state agency, and including explanatory factors relating to project type, project environment and contract bidding characteristics. The demonstrated methodology can help agencies identify the factors that contribute to time delays and to better predict them.
