• Abstract:
  The Michigan Department of Transportation (MDOT) has been using monetary incentive payments for many ; years to accelerate highway construction work, resulting in reduced delays to the traveling public. It was ; envisioned that incentive/disincentive (I/D) payments/penalties would capture the true cost (user delay savings ; vs. actual I/D dollars) and would have positive impacts on the long-term pavement performance by extending ; its expected life. Therefore, MDOT sponsored this research study to determine whether the I/D for expediting ; construction captures the true cost and identify its impacts on the long-term pavement performance for projects ; that have been expedited vs. conventional scheduling. The analyzed data statistically supports an improvement ; in the long term project performance for the incentive projects. Also, identified data suggests a trend that incentive ; clauses accelerate project schedules. Additionally, data analysis statistically supports the idea that incentive ; clauses increase project cost but further analysis finds that the avoided user delay was higher than the additional ; paid cost for some incentive clauses. The analysis results highlight the effectiveness of Accepted for Traffic and ; Interim Completion incentive/ Disincentive clauses; they also debate the effectiveness of the lane rental incentive/ ; disincentive clauses, in achieving their goal by accelerating project schedules and reducing user delay cost. Also, ; the report calls for little modification to the listed “Advantages and Disadvantages” and “Recommendations for ; Use” of each acceleration technique in the 2013 MDOT Innovative Construction Contracting document.
