Sophisticated software was used to model and plan the bridge slide.
Sundt is using innovative technology to help build challenging projects – projects that are key to solving the nation’s infrastructure crisis. Take the 87-year-old Sellwood Bridge in Portland, Ore., for example, which Sundt is reconstructing with joint venture partner Slayden Construction.
As shown in this short video, the team used 3D virtual construction and Building Information Modeling software to develop and communicate a bold idea: that a 1,100-foot-long segment of the failing bridge could be lifted and moved aside onto temporary piers while the new bridge is constructed in its place. The technology was used to present the idea to the client, Multnomah County, and ultimately win the job for three good reasons: it will shorten the construction time, save money, and keep the bridge open during construction.
“Beyond using the model to create short animations, Slayden/Sundt is also using mobile technology to put the 3D model on mobile devices available to field crews,” said Eric Cylwik, Sundt Senior Virtual Construction Engineer. “This affords crews the ability to review detailed models to ensure proper communication.”
Slayden/Sundt is replacing the aging Sellwood Bridge with a two-deck, steel arched bridge that will improve safety and traffic flow over the Willamette River. The new bridge will have two vehicle lanes in each direction on the west end, which narrow to one lane in each direction on the east end. In addition, it will have two, six-foot-wide bike lanes and two, 12-foot-wide sidewalks.
The $210 million, heavy civil construction project is scheduled for completion in November 2016.

The rebar cage that Slayden/Sundt will use to set the shaft before placing concrete around it. The cage is 220 feet long and weighs approximately 175,000 pounds.
The summer and early fall have been busy for Slayden/Sundt as the joint venture reconstructs the 2,000-foot-long Sellwood Bridge in Portland, Ore. The team has been focused on constructing the in-water piers that will support the three new spans over the Willamette River. Each pier consists of four drilled shafts that are 10 feet in diameter and up to 176 feet below the river bottom (the river is approximately 30 feet deep).
Environmental permitting constraints have left the team with a tight window to complete the drilled shafts and construct/install the perched boxes around the concrete columns. The perched box caissons will allow crews to complete the construction of the piers over the next nine months. They will be installed with cranes and pile drivers above water, and by divers below the water. Building Information Modeling (BIM) is being used to pre-plan the work thoroughly for maximum efficiency and safety.

The $207 million, heavy civil construction project involves replacing the aging Sellwood Bridge with an open steel deck arch structure. The project team is using an innovative “shoofly” (detour) approach to complete this complex project, which is explained here. This short video shows the successful bridge slide that took place last January.

Sundt employees Fred Stone and Godfrey Linsangan accepted the USACE award on behalf of Sundt. Also pictures are USACE quality assurance personnel.
The U.S. Army Corps of Engineers (USACE) has recognized Sundt with its prestigious Large Contract Safety Award for the first quarter of 2013 in recognition of our safety record at the William Beaumont Army Medical Center project at Fort Bliss in El Paso, Texas. The heavy civil construction project involved preparing the 320-acre site for a future hospital that will serve members of our armed forces.
“This was a very demanding job with a tight, 12-month schedule,” said Sundt Regional Director Fred Stone. “The safety on the project was great; it was our priority from day one. There was a tremendous amount of work going on with some very deep excavations and multiple disciplines of work happening at the same time.”
Sundt’s $47.5 million project included: 600,000 cubic yards of mass grading; 35,000 lineal feet of water line installation; 10,000 lineal feet of storm drain installation; 29,000 cubic yards of concrete paving; 23,000 lineal feet of sewer main installed at depths of up to 50 feet; 1.2 million cubic yards of excavation and backfill just for the sewer main; construction of a precast concrete bridge over an adjacent highway; and construction of an electrical substation.

An aerial view of the reconstructed Cordes Junction Traffic Interchange
Sundt and joint venture partner Vastco, Inc., have nearly completed reconstructing the Cordes Junction traffic interchange, located about 65 miles north of downtown Phoenix at Interstate 17 (I-17) and State Route 69. Traffic has been placed into its ultimate configuration to prepare for the final lift of rubberized asphaltic concrete pavement. Crews are currently scheduled to pave the project during the month of June followed by final striping and signage. The project is expected to be complete in July.
The Construction Manager at Risk project included the construction of seven new bridges, including a post-tensioned, cast-in-place concrete structure that was built over live traffic on I-17. The Heavy Civil team also built two separate interchanges – one for through traffic and one for local – and realigned, widened and paved several streets. The 50-year-old interchange is used by approximately 40,000 vehicles per day.
Sundt is pleased to announce that Shane Henry has been promoted to senior project superintendent working in our Sacramento office. Shane has been with Sundt for 15 years and has contributed to several projects in California, including construction of the Sierra Vista Hospital in Sacramento, University of California Merced Social Science and Management Building in Merced, Calif., and Dublin Fairway Ranch Family Apartments in Dublin, Calif. He is currently working on Tercero Student Housing Phase III at the University of California, Davis.
How did you get started with Sundt?
I started out with Sundt as a journeyman carpenter on a heavy civil construction project.
What changes have you observed in the construction industry over the years?
Technology has become a big part of our industry. It has changed the way we do business today compared to 15 years ago, and it will continue to do so.
Describe the kind of work you do in your new position.
I will have more involvement with clients and customers for the overall project.
What do you enjoy most about your job?
I get the chance to make a difference in the development of the project and overcome issues.
What’s the biggest drawback?
Time – there are never enough hours in the day.
What might you be doing if you weren’t working in the construction industry?
I will always be where the rubber meets the road. So if I was not in the construction industry I would probably be in tooling or manufacturing.
What’s your dream vacation?
Always thought it would be nice to visit New Zealand.
Most recent book or movie that you enjoyed?
I’m reading the Hatchet series by Gary Paulsen with my son.
Favorite kind of food?
How do you like to spend your free time?
I like camping and fishing with my family. I like to go on back road trips and am always looking for new places with no people around.
