Designed as an open steel deck arch structure, the new Sellwood Bridge will complement its surroundings while providing ample space for all modes of travel.
When you combine Sundt’s size and proven ability to be innovative with the knowledge and experience of a local contractor, you get a project like the $160 million reconstruction of the Sellwood Bridge in Portland, Ore. Sundt and joint venture partner Slayden Construction used Building Information Modeling (BIM) and a sophisticated video presentation to develop and propose a faster, safer and less expensive method for reconstructing the aging bridge than was originally called for in the project’s Environmental Impact Statement. The approach will shorten the project schedule by approximately one year and reduce the cost to the owner, Multnomah County, by $5 to $10 million.
The 86-year-old Sellwood Bridge stretches 2,000 feet across the Willamette River. Rather than rebuilding it in sections and shifting traffic back and forth between the old structure and newly completed segments, the team will create a ”shoofly” (detour) bridge to keep traffic flowing throughout the project. The approach involves lifting the old bridge deck and truss with hydraulic jacks and moving it to one side, then placing it on a set of temporary piers and connecting it to temporary approach spans so that traffic can continue to use it while the new bridge is constructed.
What are the benefits? Creating a detour bridge is safer for construction crews and the public because it frees up the existing alignment for workers and keeps traffic out of the construction zone. By eliminating the need for complicated traffic phasing, it also shortens the project duration and therefore the overall cost. Another benefit is that it allows for a sleeker bridge design with fewer redundant features and fewer in-water impacts, which is better for the river’s ecosystem.
The new Sellwood Bridge will be complete and efficiently transporting motorists, bicyclists and pedestrians across the Willamette River in 2015.

Sundt has been building projects for the United States military since 1902, when horses still played a prominent role in our nation’s defenses. Fast forward more than 100 years and we are still building high-profile jobs for our armed forces – albeit of the non-equine variety – including one of the Naval Facilities Engineering Command’s (NAVFAC) top priorities: a training facility for the F-35B, a highly sophisticated joint-strike-fighter (JSF) aircraft that has short takeoff, vertical landing, and stealth capabilities. When the first F-35Bs are introduced next year, they will become the principal, elite aircraft supporting Marine Corps reconnaissance and combat missions around the world.
Sundt’s $18.4 million contract is to manage the design and construction of a 43,000-square-foot JSF flight simulation facility for the F-35B at the Marine Corps Air Station in Yuma, Ariz. As the second project of its kind in the United States – and the first west of the Mississippi River – it will be used to train pilots through the use of 12 JSF simulators that replicate real-world missions and challenges while saving on fuel costs and aircraft maintenance. The facility will also house mission briefing and de-briefing rooms, administrative space and offices.
Because the engine, avionics and weapons systems of the F-35B are highly classified, the project area – not to mention the base itself – has extremely tight security. Sundt’s crew members and subcontractors have gone through extensive background checks to gain clearance and site access. Another challenge is the project’s fast-track, 12-month schedule: construction began in June 2011 and must be complete by June 1, 2012 in time for the arrival of the first squadron of pilots for training.

Sundt employees installing pervious concrete
Sundt is paving the way to better value for our clients with the use of pervious concrete, an innovative product that helps owners lessen the environmental impact of their projects – and possibly save money at the same time. Embracing this green product – and investing in the training and equipment that go with it – is just one of the ways Sundt is distinguishing itself as a leader in sustainable construction.
How does pervious concrete work? When rainwater sheets over large areas of impermeable (traditional) concrete, it picks up many pollutants which it then carries to treatment facilities, rivers and streams. Pervious concrete is different because it’s designed to be porous so that rainwater can pass directly through it, thereby reducing storm water runoff – and pollution – and recharging underground water supplies.
On new construction projects, pervious concrete can be designed to be the site’s main storm water retention system, which allows for less elaborate (and less expensive) sewer systems and other drainage features. In many cases, using pervious concrete allows a larger area of a project site to be developed, which, for owners, translates to greater value.

Sutter Hall at California State University, Chico
Like many Sundt projects, the original design of the Sutter Hall dormitory at California State University, Chico had green building practices at the forefront. Prior to starting construction on the building, owners and project partners believed that the 111,000-square-foot complex would meet the U.S. Green Building Council’s standards for LEED Silver certification. However, everyone was beyond thrilled when Sutter Hall, which opened in late 2010, was recently awarded Gold certification, the second highest level of green building certifications.
The $60 million Sutter Hall complex combines student housing, residential dining and programming centers. Although the project was well positioned during design and preconstruction phases to achieve LEED silver, the team met regularly to review the project’s status and seek out any potential opportunities for additional eco-friendly features. Such opportunities arose, including the option to utilize natural light for daylighting and to increase the facility’s performance through the use of recycled content and regionally based building materials. Such diligence allowed the project team to seize opportunities and capture the three additional LEED certification points identified prior to construction. The final point – which bumped the project from Silver to Gold – came as a result of Sundt’s green building experience, allowing the team to identify a Credit Interpretation Request to capture the point for Brownfield Redevelopment.
We offer our congratulations to the CSUC Sutter Hall project team for its teamwork and ability to find and seize opportunities! Here’s to going gold!
