Accelerated Construction Technology Transfer (ACTT) is a strategic process that uses various techniques and technologies to reduce construction time on major highway projects while enhancing safety and improving quality. The process is implemented by conducting 2-day workshops for State DOTs. The American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA) jointly fund ACTT workshops.
In March 2004, the Washington Department of Transportation (WSDOT) hosted a workshop that brought together transportation experts from many states. The primary objective of the workshop was to draw on the expertise of participants to help WSDOT achieve its goal of minimizing construction time for its SR-520 project between I-5 and I-405 in Seattle. The cost of this project will be between $1.5 and $3.4 billion, depending on the selection of the number of lanes for the new facility, making this the largest ACTT project to date. The project presents many challenges such as the replacement of a 40-year old floating bridge across Lake Washington and moving as many as 120,000 vehicles per day across the lake while the floating bridge is under construction.
Opening the workshop on March 16 were three officials representing WSDOT: the FHWA Washington Division Administrator, WSDOT's Assistant Secretary Of Engineering, and the Project Director.
Following the opening remarks and a project tour, the participants spent a day and a half brainstorming, looking for methods and measures that would help achieve project goals. The workshop was unique in that three large multidisciplinary teams were formed to evaluate three separate stretches of the highway, rather than grouping participants based on their areas of expertise, as is the norm.
The Skill Sets that attended the WSDOT's workshop were: Environment; Geotechnical/Materials/Accelerated Testing; Structures; Right-of-Way/Utilities/Railroad; Innovative Financing/Contracting; Roadway/Geometrics; Traffic Engineering/Safety/ITS; Construction; and Long-Life Pavements/Maintenance. The teams presented numerous ideas and recommendations, many of which were deemed viable and will be pursued, according to WSDOT. Among these recommendations were:
With the workshop now completed, it remains for WSDOT to sift through the reports produced by the Skill Set groups and decide which ideas should be implemented in future planning, design, and construction phases of the project. At the close of the workshop, it was agreed that the suggestions presented could result in a 1- to 2-year savings in construction time
