1. Workshop Details
1.1. Opening Session
Participants convened for registration and the opening session of the US 421/I-40 Business in Winston-Salem ACTT workshop on the afternoon of April 24, 2006.
Following opening remarks from FHWA Construction and System Preservation Engineer Chris Schneider and NCDOT Director of Construction Steve DeWitt, workshop attendees introduced themselves. NCDOT Board Member Nancy Dunn and NCDOT Division Engineer Pat Ivey provided an overview of the project corridor, discussing project issues, constraints and key stakeholders.
North Carolina FHWA Division Administrator John Sullivan illustrated the ACTT process with a "Why ACTT, Why Now" presentation, after which Chris Schneider and FHWA Resource Center Pavement Management Engineer Joe Huerta wrapped up the day with an overview of the brainstorming process and overall workshop format.
1.2. Workshop Process
The NCDOT workshop followed the traditional ACTT process. On Tuesday morning, the skill sets met individually to discuss the project and brainstorm preliminary ideas, reconvening as a group before lunch to share their initial thoughts. After lunch, the skill sets continued their work, intermingling with other teams to ask questions and convey ideas. They spent the remainder of the afternoon preparing final recommendations for presentation to the group on Wednesday morning.
1.3. Skill Set Goals
The project team shared a number of corridor goals with workshop attendees:
- Deliver the project at a reasonable cost and with the least amount of inconvenience to NCDOT customers. Utilize innovation in design, letting and construction methods to achieve these goals.
- Replace deficient structures and provide the requisite vertical clearance.
- Improve the rideability of the roadway to current NCDOT standards.
- Improve the existing roadway condition.
- Construct the project with the least possible interruption to businesses, commuters, residents and events.
- Reduce impacts to traffic.
- Minimize overall construction time.
In addition, participants in each skill set had an established group of goals that was unique to their subject area:
Utilities/Railroad/ROW/3rd Party Constraints
- Determine utility corridors.
- Identify environmental issues.
- Eliminate and/or avoid utility conflicts prior to construction.
- Coordinate scheduling.
Historic Properties/Human Environment/Public Involvement
