Geoforensic Evaluation of City of Sugar Land Police Station/Court Building

President, Geotech Engineering and Testing (GET)
The Sugar Land Police Department/Court Building, located at 1200 Highway 6 South in Sugar Land, Texas has experienced foundation and structural movements. These movements have resulted in cracks and separations in the wall, sheetrock, tiles, and floor slabs. The existing building consists of a two-story building with a steel frame and brick veneer structure. The main structure was built in 1996. The wings were added in 2004. The building is supported by a spread footing-type foundation in highly expansive soils.
The purpose of our study was to (a) identify the causes of foundation movements and (b) recommend repair techniques that would reduce future movement and cracking of the structure. These objectives were met by (1) conducting site visits, (2) performing a geotechnical study, (3) conducting laboratory testing, (4) reviewing existing data and reports by others and (5) analyzing the data to develop engineering recommendations.
The causes of the foundation distress for the subject building could be attributed to (a) inappropriate design, (b) improper construction, (c) using wrong fill materials, (d) negative drainage around the building, and (e) the presence of large trees in close proximity to the building. It should be noted that the foundation system for the building has not technically failed. However, we anticipate potential foundation movement due to the deficiencies stated above.
David Eastwood is the Past President of the Houston Chapter of the Texas Council for Engineering Laboratories. Mr. Eastwood is the founder and past president of the Foundation Performance Association, an organization specializing in foundation failure evaluation. He is a fellow at the Foundation Performance Association (F.FPA) and the Post-Tensioning Institute (PTI).
