32 INTRODUCTION The data and literature review show that several STAs have conducted studies to develop a comprehensive description of ACMs, define their selection criteria, and evaluate previous experience. In a study performed by the Center for Transportation Research and Education, Iowa State University, for the MnDOT, several performance measures such as cost and value were compared between A+B bidding, design–build, lane rental, and traditional contracts.

33 other groups affected by the project. Good candidates are mill and overlay projects, concrete overlays, detour projects, new construction and reconstruction projects, bridge painting, intersection upgrades, and bridge rehabilitation projects.

reduction continues for each time period beyond the completion date until the work is completed or the incentive is zero. If the work has still not been completed, the contractor will then be charged liquidated damages.

37 It also encourages minimization of construction time for highpriority projects by offering the contractor a bonus for early project completion and a penalty for late project completion. Criteria for Selection The selection criteria for A+B bidding includes projects in which construction creates considerably high road user delays, safety or other negative impacts on the community, or that has received high public interest in its expedited completion and for which the department seeks to use the contractor's knowledge and experience to achieve this.

from the delays caused by lane closures; the disincentive can be different for different segments or ramp configurations. Criteria for Selection Unauthorized lane use should be limited to high-profile projects that may cause considerable delays to road users and that have the potential to create significantly escalating road user costs if the specified road closure times are not strictly adhered to.

39 ACM is to achieve lower costs while reducing project durations. The method is done in three sequential stages starting with preparation of partial design package by PennDOT, selection of the design–build contractor based on the required criteria, and finally project completion.

• Typical Project Profiles -- Areas that are sensitive to high traffic volumes, such as business or tourist areas, are the best candidates for application of this delivery method. It can also be used for projects where construction leads to increased safety concerns or affects an environmentally sensitive area.
