Last month, when an 18-wheeler crashed into a utility bridge on the I-10, damaging utilities and halting freeway traffic through downtown El Paso, the Texas Department of Transportation (TXDOT) called upon the Sundt Go 10 project team for help. While the incident did not occur within our project limits, it was close enough for TXDOT to request Sundt’s assistance. Our crews mobilized within hours and worked from 4:00 pm on Thursday afternoon, July 12th, until 3:30 am on Saturday morning, July 14th, to re-open the I-10 and restore a critical part of the city’s infrastructure.
The semi-truck lost control and drove up the embankment, crashed into the bridge, and caught fire immediately.
“It was a great team effort,” said Senior Project Manager Rudy Elias. “When TXDOT called, we were in our weekly cost meeting, and within hours we had people at the crash site inspecting the damage.” Having secured a crane and other necessary equipment, Sundt crews set about cleaning up the accident, shoring the bridge and shifting traffic around the site until more permanent fixes were put in place. “We had crews working around the clock, some guys more than 20 hours in a row,” Rudy said. “There was even one, Thomas Edmonds, who canceled his flight to San Diego for the weekend and stayed to finish the job.”
Fortunately, the driver walked away from the accident only suffering burns to his feet and an injury to his shoulder, according to El Paso’s Channel 9 KTSM.
Staying true to Sundt’s core value of Customer Focus, the Go 10 project team worked tirelessly to exceed owner expectations. As our Transportation Group continues to grow its presence in Texas, their willingness to go the extra mile—to help in times of crisis and solve difficult challenges—is going a long way towards earning clients’ trust.

Sundt won the Build America Award in the Highway and Transportation Renovation category for its work on the West 7th Street Bridge in Fort Worth, Texas.
An innovative water treatment facility and an iconic bridge had something in common last week when they both won prestigious Alliant Build America Awards from the Associated General Contractors of America (AGC) at the AGC’s 96th Annual Convention in San Juan, Puerto Rico. Sundt won the Environmental Enhancement category for its work on the Ocotillo Brine Reduction Facility renovation construction project in Chandler, Arizona, and the Highway and Transportation Renovation category for the West 7th Street Bridge in Fort Worth, Texas.

The $75 million Ocotillo Brine Reduction Facility project was completed in April of 2014. A global semiconductor manufacturer selected Sundt and Carollo Engineers, Inc. as the design-build team to reconstruct the water treatment plant, which supports the City of Chandler’s Reverse Osmosis Facility (CHRO) as it treats additional waste streams brought on by the manufacturer’s recently built Ocotillo Campus fabrication facility. The water treatment construction project included modifications to the existing CHRO influent pump station, a modified finished water pump station, a repurposed brine concentrator, sludge storage, a sludge dewatering facility with belt filter presses, repurposed brine evaporation ponds, chemical feed systems, electrical buildings and instrumentation, and supervisory control and data acquisition programming and upgrades.

The West 7th Street Bridge connects downtown Fort Worth with the city’s thriving cultural district, and is the first structure of its kind in Texas. Its 12 precast, post-tensioned arches were built offsite and moved into place on either side of the existing bridge before it was demolished and reconstructed – in just 150 calendar days. The bridge construction project was completed a month ahead of schedule.
Build America Awards honor the builders of the nation’s most impressive construction projects. They recognize excellence in state-of-the-art advancement, project management, innovation, sustainability, client services, community contributions, safety and meeting the challenges of a difficult job.

What’s that floating toward the Sellwood Bridge project in Portland, Oregon? Barges transporting the giant steel arches that will support the new bridge being constructed by Sundt and joint venture partner Slayden Construction for Multnomah County.
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. There will be 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 team is using a “shoofly” (detour) approach to complete this project. They lifted the old bridge deck and truss with hydraulic jacks and moved it to one side, then placed it on a set of temporary piers and connected it to temporary approach spans so traffic can continue to use it while the new bridge is constructed.

Slayen/Sundt poured 1,420 cubic yards of concrete at pier 5 – a key milestone in the 47-month project.
The Sellwood Bridge project in Portland, Oregon achieved two important milestones last month when Sundt and joint venture partner Slayden Construction placed nearly 3,000 cubic yards of concrete at the foundations of piers 4 and 5, located in the Willamette River. The concrete pours represent significant achievements in the 47-month, $216 million project to replace the aging bridge with a new structure that is wider, safer and seismically sound.
Discharge water cascades from the cooling system the team developed to control the temperature of the concrete as it cured.
The concrete milestones also represent impressive accomplishments in value engineering and ingenuity. Piers 4 and 5 are massive concrete structures comprised of reinforcing steel and 6000 psi concrete. Slayden/Sundt’s own workforce used specialized concrete placement techniques to control the excessive – and potentially damaging – heat that was created during the curing process.

“As fresh concrete hardens, or ‘cures,’ heat is generated as a byproduct of the chemical reaction,” explains Sundt Project Engineer Matt Fisher. “Due to the very large mass of concrete at piers 4 and 5, this ‘heat of hydration’ is generated faster than it can naturally dissipate, which could result in excessive internal temperatures and possible damage to the concrete.”
As a solution to this problem, the team designed an internal water-cooling system to remove the excess heat from the concrete. Water pumps, manifolds, intake screens, valves, flow meters and thousands of feet of flexible plastic water tubing were carefully placed throughout the concrete formwork. After the concrete was placed at the piers, cool water was continuously pumped through the plastic tubes, which in turn carried away the excess heat from the concrete. Remote temperature sensors were also placed throughout the fresh concrete to collect temperature data. As the concrete cured, and the internal temperatures climbed, this data was constantly monitored to confirm the performance of the cooling system and to ensure a quality product.

Crews closed Interstate 10 in San Antonio for just five hours while installing 164-foot-long girders at Ralph Fair Road.
In San Antonio last Saturday, Interstate 10 (I-10) was closed for just five hours while Sundt installed the longest precast, pre-stressed concrete bridge girders in the history of the Texas Department of Transportation – and then traffic was flowing smoothly again. The operation was part of Sundt’s $6.1 million transportation construction project on I-10 at Ralph Fair Road, in which our team of expert builders is planning and constructing a new overpass to expand the existing FM 3351 bridge to accommodate growing traffic volumes.
The nine 164-foot-long girders were transported approximately 40 miles to the site from the precast concrete plant and then installed with two hydraulic cranes in less than two hours. The girders form part of the backbone of the new overpass, which is expected to be complete and open to traffic next spring. Another 17 girders will be installed in the coming months.
“Everyone from Sundt, from supervision to craft employees, helped get this challenging task accomplished safely, and with minimal effects on motorists,” said Sundt Senior Project Manager Gustavo J. Anguiano. “Our team held many meetings with the owner, subcontractors and beam supplier to plan and walk through every aspect of the activities beforehand so that things went smoothly.”
