Sundt is beginning the final stages of a $68 million project to improve a segment of Loop 375 Transmountain Road near El Paso, Texas. The team is finalizing the grooving of the bridge decks and putting the final finishes on the stamped concrete under the new bridges. Overhead sign structures are in place and landscaping is about 70 percent complete. What’s left before the project is complete in mid-May? Traffic signalization, electrical work below some of the bridges, and asphalt paving.
The heavy civil construction project includes widening the 3.5-mile stretch of roadway from two to four lanes (with frontage roads), building four grade-separated intersections, hiking and biking trails, and exit and entrance ramps. The project also includes direct connectors from Loop 375 west to Interstate 10 east and I-10 west to Loop 375 east.

Sundt created a 3D model of the new sewer line to identify potential conflicts with other utilities.
Don’t like conflict? If it’s utilities you’re talking about, 3D modeling might be the answer. That’s how Sundt identified potential problems – and showed our client how to solve them – on a roadway reconstruction project in El Paso, Texas.
“After evaluating the planned sewer line corridor and comparing it to the existing utilities, we found several potential conflicts,” said Rob Manning, Sundt Project Manager for the $14 million Country Club Road widening project. “We collected data by uncovering the actual utilities through potholing, then took GPS survey shots of each utility and created a 3D model that includes the planned sewer line placement. We presented our findings and suggestions to the city and its engineer, and they used the information to redesign that portion of the project.”

The heavy civil construction project involves reconstructing two miles of Country Club Road in a well-established area of the city. Lined with prominent, high-value homes and many businesses, the roadway is badly congested and sits atop several aging utilities that need to be replaced (and whose exact location wasn’t known until Sundt began investigating). Sundt’s scope includes widening and reconstructing the roadway with continuously reinforced concrete paving, replacing the water and sanitary sewer lines, and installing sidewalks, lighting, landscaping and a traffic roundabout.

It stands to reason that a cutting-edge light rail construction project would make use of innovative communication technology to keep the public informed about the project. That’s exactly what’s happening in Phoenix, Ariz., where Sundt and joint venture partner Stacy & Witbeck are constructing a major extension of the city’s light rail system, known as the Northwest Extension.
While the public awaits the heavy civil construction project’s completion in April 2016, they can use an application developed by the project team to stay connected with area businesses and get project updates. The “NWExtension” app, available for free in the Apple iTunes store, contains coupons, business promotions, route information, construction updates, information about community groups, traffic impacts and more. The idea for the app grew out of the team’s business assistance efforts.
“The project team has done a phenomenal job helping us out – way above and beyond what anyone would expect,” said Luis F. Granda, who works for a company that until recently owned a car wash on 19th Avenue, where most of the construction is taking place. “I think the app is an incredible idea. I have it on my phone right now. I know that our customers have downloaded it and that it has helped our business because it has so much great information.”
In 2008, Sundt and Stacy & Witbeck completed more than half of the original 20-mile “starter” section of the Valley Metro Light Rail transit system (Line Section 4 and Line Section 5), plus the system’s maintenance and operations facility.

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.
BIM is being used to plan the construction of the perched box caissons.
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.
