Fostering Innovation Interstate Route H-1 Viaduct Improvements
Why ACTT, Executive Summary, and Workshop Details
- ACTT provides a fresh outlook by bringing national experts to your planning table.
- ACTT introduces innovations that have been tested elsewhere.
- ACTT saves time: according to FHWA's ACTT II report, published in March 2005, "most agencies have found ways to slice construction time by 30 percent or more."
- ACTT saves money: ACTT suggestions enabled New Jersey to reduce its budget for the Route 46 bridge project from $10 million to $7.2 million.
- ACTT works for you and your customer!
How Do I ACTT?
- Select a corridor: ACTT is most helpful when applied during the project development phase.
- Make a workshop proposal to ACTT team members, and submit a copy of your proposal to theFHWA Division Office. Include details on the project corridor, timeline and goals.
- Hold a pre-workshop meeting with the ACTT management team.
- Select a meeting site, and coordinate workshop details with theFHWA Division Office.
- Host the workshop.
- Draft a report for submittal toFHWA.
- Incorporate ACTT into project operations.
"This is what this is all about - doing what you have
inside of you to make a difference."

Those familiar with the Accelerated Construction Technology Transfer,
or ACTT, process will tell you that comments such as the one made by
Jim Sorenson during his closing remarks at the Hawaii ACTT workshop
on April 20, 2006, are an accurate reflection of how Accelerated
Construction Technology Transfer impacts the project planning
That's because ACTT brings together a host of national experts who
are committed to fostering innovation, saving time and money, and
minimizing inconvenience for the department of transportation's
(DOT's) ultimate customer, the traveling public.
The traveling public was very much on the Hawaii Department of
Transportation's (HDOT's) mind when it approached the Federal
Highway Administration (FHWA) about hosting an ACTT workshop
for the Interstate Route H-1, Pearl City, Waimalu and Airport Viaduct
Deck Improvements project: steadily increasing traffic volumes and
deteriorating deck conditions were prevalent throughout the corridor,
and funding constraints meant that the public could face up to five
years of construction. HDOT found this timeframe - and the potential
public impact - unacceptable.
Together, FHWA and HDOT established the following skill sets for the
Interstate Route H-1, Pearl City, Waimalu and Airport Viaduct Deck
- Innovative Contracting.
- Traffic Engineering/Safety/ITS (Intelligent Transportation Systems).
- Public Relations.
Each skill set team focused on how the ACTT process applied to their
area of expertise, while the group as a whole searched for methods
and measures to help HDOT achieve its goals of reducing project costs
and accelerating the construction timeframe by at least 50 percent.
As the workshop progressed, each team summarized their thoughts
and narrowed them down to a list of priority recommendations. On the
final day, each skill set presented their suggestions to the conference
attendees. Now that the workshop is complete, HDOT will sift through
the various recommendations and decide which ideas should be
implemented as part of the Interstate Route H-1, Pearl City, Waimalu
and Airport Viaduct Deck Improvements project.
1. Workshop Details
1.1. Opening Session
HDOT hosted the ACTT workshop April 18-20, 2006, at the Hilton
Hawaiian Village in Honolulu, Hawaii.
The workshop began with a tour of the project corridor on Tuesday
morning. Following registration, the attendees gathered for the
opening session. HDOT Director Rodney Haraga and Hawaii FHWA
Assistant Division Administrator Vince Mammano provided opening
remarks, after which the participants introduced themselves. HDOT
State Bridge Engineer Paul Santo provided a project overview, and
Caltrans Deputy Director Randy Iwasaki discussed "Why ACTT, Why
Now." FHWA Construction and System Preservation Team Leader Jim
Sorenson served as session moderator.
1.2. Workshop Process
FHWA Baltimore Resource Center Contract Engineer and Work
Session Moderator Jerry Blanding began the second day with an
overview of the day's agenda, after which North Carolina DOT
Administrator Len Sanderson discussed the brainstorming process.
The skill set teams then broke apart to discuss the project and
brainstorm preliminary ideas. Before lunch, the group reconvened
to share their initial thoughts. After lunch, the skill sets continued
their work, intermingling with other teams to ask questions and share
ideas. They spent the remainder of the afternoon preparing final
recommendations for presentation to the group on Thursday morning.
1.3. Skill Set Goals
The overall goal for the ACTT workshop was to explore innovations for
constructing the deck improvements to the viaducts in a timely manner
while minimizing impacts to the traveling public and the environment.
In addition, participants in each skill set had an established group of
goals that was unique to their subject area.
- Address construction sequencing.
- Identify contractor staging and material storage areas.
- Maintain safety of construction workers and the traveling public.
- Recommend innovative construction methods that will minimize cost and the construction timeframe.
- Partner to reduce cost and duration.
- Maintain traffic flow at target miles per hour (MPH).
- Provide access throughout the construction zone.
- Provide reasonable project length for the contractor to complete work in a compressed timeframe.
- Reduce the estimated total construction time down to one to two
years from the initial five-year estimate.
- Reduce the estimated construction cost by 50 percent.
- Evaluate multiple contracts versus one large contract.
- Consider A-plus-B and A-plus-B-plus-C bidding opportunities.
- Discuss alternate funding mechanisms.
- Minimize cost and duration.
- Consider advance construction contracts.
- Explore innovative construction methods that could minimize
both the cost and the project timeframe.
- Evaluate design-build (D-B) options.
- Consider parallel/alternative detour routes and low-cost
improvements to facilitate traffic movement.
- Maintain the existing number of lanes on H-1 to the maximum
- Reduce congestion during peak hours, and consider methods to
- Minimize impacts to traffic.
- Establish traffic patterns that are clear and well-signed.
- Ensure contractor and motorist safety.
- Enhance travel and accessibility to the surrounding areas, major
employment areas, medical facilities and local activity centers.
- Implement an incident management system and a freeway
service patrol contract.
- Maintain traffic at all interchanges and cross streets to the extent
- Consider truck traffic options.
- Consider other area projects and traffic detours.

- Recommend bridge types and construction methods that will
minimize the timeframe for replacement of the existing bridge
decks, where applicable.
- Use prefabricated components to the maximum extent practical.
- Use high-performance materials such as very high early-strength
concrete where practical.
- Integrate connections to existing roadways.
- Consider alternatives that provide for rapid construction while
- Identify and minimize project impacts.
