Camden Post Oak Residential Tower
Paradigm provided an extensive geotechnical study for this 34-stories facility with a ground floor footprint approximately 45’ x 270’ plan dimension. The tower is cast-in-place concrete and was constructed using a tunnel form system. Initially, a mat foundation system was desired. However, because of excessive settlements, Paradigm recommended to the design team that an alternate foundation system be considered. The foundation for the tower was augered cast-in-place piles with a grade-supported floor. Two pile load tests were used to confirm the recommended capacity. The five-story, steel frame garage structure is 170 feet by 240 feet in plan dimension.
The site was previously developed with a six-story office structure which was demolished to accommodate the new structure. The foundation for this structure was partially located within the new building footprint. The impacts of the former foundations were considered in recommendations for the foundation and floor system. The Client elected to remove the 20-ft deep foundations and to backfill the excavation. Given the depth of excavation, controlled compaction was critical to result in desired performance of the grade-supported floor and to develop frictional resistance for the piles. Paradigm provided recommendations for structural fill and worked with the contractor to identify fill sources and to assure fill quality during backfilling operations. Paradigm provided monitoring and quality assurance for the Owner throughout construction.
Within the garage footprint, a large diameter utility had to be relocated and considered in the foundation system. Shallow spread footings were used to support the garage loads. Paradigm provided materials testing quality assurance throughout utility relocation and garage construction for the Owner.
