IH 10 reconstruction
HVJ Associates, Inc. performed a geotechnical investigation
for the $1 billion Katy Freeway expansion, located westward
from Houston's IH 610/IH 10 interchange to the City of
Katy, a distance of about 20 miles. The freeway will be
expanded from the current eight lanes to 14 lanes. HVJ
conducted approximately 600 borings as part of a soil
and bedrock investigation along the entire length of the
future roadway. The IH 10 reconstruction, which includes
improvements to numerous underpasses and overpasses, and
the construction of detention ponds, sound walls, and
culverts, is one of the most ambitious transportation
projects ever undertaken by the State of Texas.

City
of Houston water and wastewater facilities
Since the late 1980s, we've provided geotechnical services
to a variety of infrastructure projects, including subdivision
water mains, improvements to water treatment and distribution
facilities, storm water facilities (detention ponds and
sewers), and wastewater facilities (treatment plants,
lift stations, force mains, and gravity sewers).

Houston
Ship Channel widening and deepening
HVJ Associates provided field exploration, laboratory
testing, and engineering analysis for three projects related
to dredging along much of the 50-mile waterway. In the
first, we evaluated properties of confined dredged material
and analyzed slope stability to determine the maximum
height dikes could be raised over soft foundation soils.
In the second project, we examined the suitability of
dredged materials for dyke construction and made recommendations
for slope configurations along portions of lower Galveston
Bay. Finally, we analyzed the design and construction
of a 6-acre, 12-foot-high island off the north shoreline
of Bolivar Peninsula in Galveston Bay. Known as Bird Island,
it is thought to be the first island designed and built
using dredged material specifically as a nesting site
for colonies of water birds such as black skimmers, egrets,
and brown pelicans.

Toyota Center
We conducted a geotechnical study for the new $175 million
sports and entertainment arena in downtown Houston. The
775,000 square-foot facility, home for the Rockets and
Comets, is burrowed almost 32 feet below street level,
giving spectators better seats and making them feel more
a part of the game. The five-story structure has
reinforced concrete floors and columns made from structural
steel and reinforced concrete. Column loads range
from 300 to 4,000 kips.

Harris County
Toll Road Authority's Westpark Tollway
We performed geotechnical studies for various segments
of this 12-mile, $250 million project in west
Houston. Based on our analysis, we made recommendations
on alignment, bridge replacements, detention facilities,
utilities, erosion, and slope stability. In another phase,
involving 86 soil borings for a proposed HOV lane, we
made recommendations on rigid and flexible pavement.

Houston
Airport System
HVJ carried out geotechnical studies at the George Bush
Intercontinental Airport for improvements to its North
and South Concourse, and for construction of a new air
cargo facility. We performed similar studies for the new
A and Y Concourses at William P. Hobby Airport.

Elementary
Schools No. 4 and No. 22, Alief ISD
The two schools, totaling more than 175,000 square feet
and built with steel frame structures on drilled and under
reamed footing, required geotechnical studies prior to
construction. We drilled 25 soil borings to evaluate soils
for foundation and pavement design. We also performed
construction testing on soils, concrete, and structural
steel.
