Wilson Packing Plant Redevelopment Omaha, Nebraska Thiele Geotech, Inc. conducted Phase II Environmental Site Assessments (ESA) and completed a geotechnical exploration study for the proposed Wilson Packing Plant redevelopment located near 27th & Y Street in Omaha, Nebraska. The project involves redeveloping the existing Wilson Packing Plant site into an industrial park. The purpose of the Phase II ESA was to address environmental concerns related to potential petroleum hydrocarbon releases from above ground storage tank (AST) systems and other waste issues onsite. The site currently consists of a multi-story building with associated facilities that were utilized as an animal processing facility and is situated on an irregularly shaped 17-acre industrial lot. Proposed redevelopment consists of demolition of the existing facilities, grading the site for industrial lots, and construction of public improvements. Public improvements will consist of installation of new sanitary and storm sewers to support the development and pavement construction. Due to the considerable quantity of concrete structures and pavements across the site much of the concrete will be crushed and recycled as aggregate fill. Approximately 50,000 cubic yards of crushed concrete fill is anticipated. Roughly 40,000 cubic yards of fill will be required to fill the deep basement of the main building. Additional earthwork will include shallow cuts from the higher elevations along the south side of the site and fills along the low-lying north side. Completion for the redevelopment is anticipated for 2003.
Q Street Improvements Millard Avenue to 156th Street Omaha, Nebraska This is a federally funded street project for the City of Omaha on one of southwest Omaha's most congested streets. It is a major east-west arterial in the area with limited right-of-way and major utility relocation. This 2-mile, four-lane urban roadway included 2,570 lineal meters of new storm sewer, more than 19,500 cubic meters of concrete, 8,350 square meters of trails, and 70,100 square meters of concrete pavement. Extensive use of retaining walls and noise barriers was required around residential portions of the project. There were also access points for commercial properties along both ends of the project. Thiele Geotech, Inc. provided materials testing services during the construction phase of the project.

Broadmoor Hills Office Buildings Omaha, Nebraska Thiele Geotech, Inc. provided geotechnical and material engineering services on three and four-story office buildings. Extensive earthwork was required to level this sloping site. Thiele Geotech, Inc. conducted geotechnical exploration studies, and recommended a drilled pile foundation to support the four-story structure. The three-story structure was supported on a shallow foundation after improving the bearing soils by overexcavating and recompacting. Construction phase services included special inspections of pile foundations, structural steel, reinforced concrete, and earthwork. The sloping site required several retaining walls for grade separation. Thiele Geotech, Inc. designed these as geogrid reinforced segmental retaining walls and prepared shop drawings. Construction of the four-story building was completed in 1999 while the three-story building was completed in 2000.
Giles Road Sarpy County, Nebraska Thiele Geotech, Inc. performed detailed design and prepared shop drawings for segmental retaining walls on Giles Road between 72nd Street and 84th Street. Widening of the roadway to 4 lanes necessitated earth-retaining structures at 10 different locations. Over 27,000 square feet of segmental retaining walls will be constructed, ranging from 4 feet to over 20 feet in height. To meet space restrictions at an existing cemetery, a steel sheet-pile system was installed using segmental block facing connected with geogrid straps. Segmental retaining walls are designed as a geogrid reinforced mass that acts as a gravity structure. The design evaluated overturning and sliding of the reinforced mass (external stability), geogrid stress and development length (internal stability), and the connection required to attach the segmental units to the reinforced soil mass (facing stability). Construction began in 1998 and with completion in 1999.
