The project includes the installation of more than 25,000 linear feet of storm drain, varying from 24 to 54 inches in diameter. The crew in the photo is placing slurry backfill over one of the 24-inch pipe runs.
Near El Paso, Texas, Sundt is improving a heavily utilized stretch of the Loop 375 Transmountain Road from Exit 6 on Interstate 10 to east of the Franklin Mountain Park entrance, bringing much-needed traffic relief to the area. The $61 million project involves widening approximately 3.5 miles of Transmountain Road from two to four lanes (with frontage roads), construction of four grade-separated intersections, hiking and biking trails, and exit and entrance ramps. The project also includes direct connectors from Loop 375 west to I-10 east and I-10 west to Loop 375 east.
Sundt Area Manager Fred Stone calls the project “a great fit for Sundt” because it makes use of our extensive heavy civil construction portfolio and our experience on projects that combine excavation, bridges and concrete work.
The project broke ground last February and is scheduled for completion in the spring of 2014. This is the second project recently awarded to Sundt by the Texas Department of Transportation. In June 2011, we were selected for the $24.1 million reconstruction of Fort Worth’s West Seventh Street Bridge.
Sundt’s work in Texas spans more than four decades and totals approximately $1 billion.

BIM is to vertical construction as VDC is to horizontal construction. If this sounds more like an SAT question to you than a cutting-edge way to build better heavy civil construction projects, read on.
Virtual design and construction (VDC) can transform the construction of horizontal infrastructure projects like highways and bridges. Sundt has become an expert in the use of VDC and the many advantages it offers clients: better communication, fewer change orders and requests for information, the elimination of rework, increased productivity and quality, shortened schedules, creation of computerized as-built drawings and specifications, and – most importantly – reduced costs.
Want to know more? Eric Cylwik and Kevin Dwyer, two Sundt employees who have become leading experts on VDC, have authored an article on the subject that was posted today on the website of ENR magazine. You can find it here.

Fort Bliss’s new machine gun target practice range is digitally controlled so that new combat scenarios can be created, generating nearly unlimited training opportunities. The concrete targets are located on the semicircles pictured above.
At Fort Bliss Army Post in El Paso, Texas, Sundt is building a target range – its third practice facility at Fort Bliss – designed specifically for machine gun training. The $7.5 million Automated Multipurpose Machine Gun Range project began in early January 2012 and is expected to be completed on January 29, 2013.
It sits on a 200-acre site that includes the range itself, a range operations and control area, classroom building, ammunition breakdown building, bleacher enclosure, range operations and storage building, operations tower, latrine, covered mess, and building information systems. Supporting facilities include electric service, paving, storm drainage, site improvements and information systems.
Sundt’s ability to self-perform all of the concrete work is playing an instrumental role in helping the team control the project’s quality and tight schedule. They created the foundations for the buildings and are manufacturing 120 concrete blocks, each measuring 2x2x6 feet, using an efficient assembly line approach.
One of the project’s biggest challenges is staying within the designated work areas, which were cleared of unexploded ordinances prior to Sundt’s arrival. (Much of Fort Bliss was used as a bombing practice range during World War II; it still includes many live bombs that restrict where construction crews can operate.) Another challenge is the limited source of water that dictates the team’s production rates.

More than half of the William Beaumont Army Medical Center infrastructure project is being performed by Sundt's own crews.
When Sundt Project Manager Greg Clark said his crew will excavate a million yards of soil at a jobsite at Fort Bliss Army Post in El Paso, Texas, some people thought he was kidding. A million yards is a LOT of material, even for a major heavy civil project like this one, in which Sundt is performing all of the infrastructure and site development for the future William Beaumont Army Medical Center.
But then Greg corrected himself – it’s actually 1.3 million yards of excavated material – and it became clear that he was serious. The massive excavation effort will allow the team to safely install a new sewer line up to 48 feet deep, beneath a large layer of sandy soil.
“The top 15 feet of the site is good quality soil, but below that it’s really sandy – just like beach sand,” Greg said. “That’s a problem when you’re trying to dig down deep because the sand runs at a two-to-one slope. It constantly runs as you dig; you can’t put a trench box in it. For various reasons, the client didn’t want to install a lift station (a value engineering idea that would have reduced the excavation depth significantly), so the only safe solution is to open up the whole area with scrapers. We will end up digging out and replacing 1.3 million yards of material to build a trench for an 18-inch sewer line.”
Sundt’s ability to dig through problems and focus on solutions is just one reason our clients choose us.

Sundt and joint venture partner Vastco, Inc., are reconstructing Arizona’s busy Cordes Junction traffic interchange at Interstate 17 (I-17) and State Route 69 (SR 69), about 65 miles north of downtown Phoenix. The 50-year-old interchange is used by approximately 40,000 vehicles per day, most of which are just passing through on their way to smaller towns in northern Arizona.
In order to alleviate congestion and improve safety, the Heavy Civil project will:
- create two separate interchanges: one that has a high-speed off-ramp from northbound I-17 to northbound SR 69 for through traffic, and a diamond interchange that has a system of on- and off-ramps designed for slower, local traffic;
- realign, widen and pave several local streets associated with the interchange;
- construct seven new bridges, including one of Sundt’s specialties: a post-tensioned, cast-in-place concrete structure that will be the most challenging aspect of the project. In order to avoid road closures, it will be built over live traffic on I-17. Vastco/Sundt’s expertise with this kind of road and bridge construction is a major reason the team was chosen for the job.
The $51 million, Construction Manager at Risk project will be complete in the summer of 2013.
