Accelerated Construction Technology Transfer
(ACTT)
pdf version (59 k)
Problem: An aging system faces increasing
traffic demand
Highway construction has intensified in recent
years to address two challenges. First, much of
the Nation's aging highway infrastructure was
built during the 1950s and 1960s and needs to
be rehabilitated or replaced. Second, although
highway capacity remained virtually unchanged
during the past several decades, traffic demand
increased tremendously, causing high levels
of congestion. Large construction projects to
improve outdated roads and bridges compound
traffic problems during extensive construction
periods. Today's motorists demand high-quality
roads, but they want them put in place as quickly
as possible; they will not settle for a "business as
usual" approach.
Putting It in Perspective Increasing demand (1980-2000):
- Vehicle miles of travel increased by 80
percent.
- Licensed drivers increased by 31 percent.
- Lane miles increased by only 3.8 percent.
An aging system:
- Forty percent of all bridges are more than 40
years old.
- When these bridges were constructed,
design life was often 50 years.
- Most pavement designs have a 20-year life
expectancy.

Solution: Accelerated Construction
Technology Transfer (ACTT) effectively
reduces construction time while enhancing
quality and safety on highways
ACTT aims to reduce construction time
dramatically, saving money and improving safety
and quality by minimizing the delays and hazards
associated with work zones.
What is ACTT?
ACTT is a strategic process that uses various
innovative techniques, strategies, and
technologies to minimize actual construction
time, while enhancing quality and safety on
today's large, complex multiphase projects.
Sponsored by the American Association of
State Highway and Transportation Officials'
(AASHTO) Technology Implementation Group
(TIG) and the Federal Highway Administration
(FHWA), the ACTT process begins with a 2-day
workshop in which a multidisciplinary team of
20 to 30 national transportation experts works
with an equal number of their local counterparts
to evaluate all aspects of a project and develop
recommendations for reducing construction time
and enhancing safety and quality.
together in a coordinated, strategic approach to
ensure that the project is completed better, faster,
and safer. ACTT skill sets include:
- Right-of-way/utilities/railroad.
- Traffic engineering/safety/intelligent
transportation systems.
- Structures.
- Innovative financing and contracting.
- Worker health and safety.
- Geotechnical/materials/accelerated testing.
- Long-life pavements/maintenance.
- Construction (techniques, automation,
constructability).
- Environment/context sensitive design.
- Roadway design/geometries.
- Public relations.
Benefits
- Reduces construction time.
- Mitigates congestion.
- Improves safety and quality.

Successful Applications: ACTT workshops
and Project Pegasus
Transportation Research Board Task Force A5T60
was formed in 1999 to promote accelerated
construction in highway infrastructure. In
2002, the task force completed two ACTT pilot
workshops in Indiana and Pennsylvania. FHWA
has continued the effort, and 21 State departments
of transportation (DOT) and toll authority owners
have hosted 24 workshops, including workshops
in California, Iowa, New Jersey, Texas, and
Washington State. Many other States are in
the planning phase for the workshop, including
Hawaii, Ohio, and New York State. In addition, as
of December 2005, at least six other States are
considering hosting a workshop.
In September 2003, the Texas DOT hosted an
ACTT workshop on how to accelerate Project
Pegasus, an initiative aimed at redesigning and
improving I-30 and I-35 East, the two major
U.S. interstates that serve downtown Dallas, TX.
These heavily congested freeways have outdated
layouts. In many locations, ramps lack adequate
acceleration or deceleration lengths, interchanges
and ramps are too close together, and bridges
have limited vertical and horizontal clearances,
among other problems. The project requires
weaving construction around railroad tracks,
major employment sites, four city parks, and the
Dealey Plaza historic district.
Workshop recommendations for accelerating the
project included using design-build contracting;
coordinating with utility companies early in
the project planning process; using long-life
pavements with a 50-year design lifespan;
improving general materials specifications;
establishing a dedicated incident management
system at the project site; and introducing various
traffic flow strategies. The goal of the accelerated
construction plan is to complete the $760 million
project in 4 years-3 years earlier than the
original estimate. Over the past 2 years, each
workshop has provided the host with a tailored
list of recommendations similar to those made for
Project Pegasus. These recommendations are at
the heart of the success of the ACTT program.
Deployment Statement
State DOTs can use ACTT to help identify
techniques and technologies that will reduce
construction time while enhancing quality and
safety. State DOTs may use Federal-aid funding,
with approval from the local FHWA Division Office,
to plan and facilitate an ACTT workshop. The
ultimate objective is to reduce construction time
and enhance quality and safety on large, complex
highway projects.
Deployment Goal
By September 2006, ACTT will be institutionalized
as a standard practice in the project delivery
process.
Deployment Status
Twenty-four ACTT workshops have been
completed so far, with five additional workshops
scheduled for the future.
