- Accelerated contract provisions (ACPs) such as cost-plus-time (A+B) and incentives/disincentives (I/D) are increasingly common, yet little is known about their pure time-cost performance effects on change orders. This study used a solid statistical methodology drawing on 1,372 highway improvement projects completed in California and was the first attempt to investigate the marginal change-order impacts of ACPs on the aspect of project schedule and cost performance. This work led to subsequent research achievement by publishing a journal article in the Journal of Management in Engineering very recently (2021), “ACT2: Time–cost trade-offs from alternative contracting methods”
