Good news for residents of San Antonio: the city’s Hausman Road Improvement Project is nearing the end of the first phase of construction. This portion of the job is mainly focused on utility work, temporary pavement construction and channel excavation. Crews began constructing a detour earlier this month to allow traffic to be switched onto the new pavement in the middle of October. What’s next? The team will begin constructing the storm drain and the first of five bridges while work progresses on utilities.
The project is the City of San Antonio’s first design-build transportation construction project. Whereas the traditional design-bid-build process separates design and construction, design-build provides a single point of responsibility for an entire project, providing significant cost and time savings and bringing more value to the owner.
Hausman Road is a two-lane roadway that connects two major highways: Loop 1604 and Interstate 10. Sundt is widening the 3.4-mile stretch between the highways to four lanes, plus a center turn lane, and constructing five new bridges. Also included in the contract are managing the extensive utility relocations; earthwork; construction of retaining walls; sidewalks, hike and bike trails; storm sewer; archeological and historic survey; environmental analysis and permitting; geotechnical work; right-of-way services and acquisitions; and public outreach.
The improved roadway is scheduled to be open in late 2015.

Concrete paving is approximately 88 percent complete at the Minot, N.D. Air Force Base.
There are approximately two months remaining in the project to repair the runway at the Minot, North Dakota, Air Force Base. To date, Sundt crews have completed approximately 44 percent of the concrete paving on this transportation construction project.
The main portion of the runway is 14.5 inches thick, widening to 18 inches thick on the outer five feet. It’s also 8,900 feet long, requiring 41,400 cubic yards of concrete and 35,650 tons of asphalt.
Once the runway paving is complete, we will groove and stripe it. Finally, we will convert the taxiway back to its intended use. For the project’s duration it was converted to function as an emergency runway.

Concrete was poured for the first section of new track at the Northwest Extension milestone event last Saturday.
It takes more than heat to keep Phoenix crowds away from an important event, especially one that celebrates a major milestone in a much-anticipated transportation construction project. Last Saturday, hundreds of heat-seasoned Phoenicians gathered to watch as concrete was poured for the first section of new light rail track for the Northwest Extension, a 3.2-mile expansion of the city’s existing light rail system.
It was the project’s second of five milestones. The next three are: station installation, vehicle testing, and the grand opening in 2016. Saturday’s milestone celebration signifies that the $158.7 million project is approximately halfway complete. Sundt and joint venture partner Stacy and Witbeck are finishing the underground construction phase while work continues on roadway widening, hardscape reconstruction and track placement. Construction of the vehicle station will begin this fall.
The Northwest Extension is expected to serve approximately 5,000 riders per day when it is complete. It is Sundt’s fourth project for the Valley Metro Light Rail. In 2008, Sundt/Stacy and Witbeck completed more than half of the original 20-mile “starter” section of the transit system (Line Section 4 and Line Section 5), plus the system’s maintenance and operations facility.

Sundt came up with several creative ways to minimize community impacts during the construction of the West 7th Street Bridge in Fort Worth, Texas. The bridge’s 12 concrete arches were constructed offsite, instead of in place, which greatly reduced the amount of time the road had to be closed.
The ability to minimize community impacts during the construction of new roadways and bridges is becoming more important to clients – and an important distinguisher for contractors. Two Sundt experts explored this topic in an article featured in this month’s issue of Roads & Bridges magazine. Click here for a link to the online version of the article, or download the pdf.
Performing challenging roadway construction projects amidst live trafffic is one of Sundt’s specialties. The Cordes Junction Traffic Interhchange Improvements Project, shown above, was completed last year by Sundt and a joint venture partner near the juncture of Interstate10 and State Route 69 in Arizona.
Sundt is pleased to be performing another transportation construction project for the Texas Department of Transportation (TxDOT). The Interstate 10 Enhancements Project includes $7.6 million in improvements to a busy, 1.3-mile stretch of I-10 in El Paso. Sundt’s scope of work includes aesthetic enhancements to bridges, walls, and concrete barriers, plus upgrades to lighting, landscape and irrigation, and hardscape. The work began last month and is scheduled to be complete in October of this year.
“This project’s biggest challenge will be working right in the middle of interstate traffic, and the tight 180-day schedule,” says Sundt Area Manager Fred Stone. “We have to be very careful in our planning, especially with the long-lead items. TxDOT pushed the start date back to allow us to gather information that will make the work go more smoothly, and right away we discovered that some of the alignments weren’t correct. Finding that out ahead of time is a huge help.”
