Arthur Capper Carroll Senior Apartments Building 1 |
| Location |
Washington, DC, USA |
| Purpose |
Foundation Preperation for Apartment Development |
Two new senior housing apartment buildings were constructed as part of the Hope VI grant for the Capper/Carrollsburg area.
These are Capper (1) and Capper (2). Capper (1) is a four-story, 160 unit building near the intersection of 5th and Virginia. Construction of Capper (2) is a 138 unit "wraparound", to the existing Carroll Apartments at 4th and M Streets began in December, 2005.
GeoStructures implemented a ground improvement package that included Geopier elements for column and wall footings, which supported a maximum load of 405 kips and 12 kips per foot, respectively; and Rapid Impact Compaction for floor slab areas. These technologies were used to improve 5 to 20 feet of uncontrolled sandy and clayey fill soils with N-values ranging from 4 to 19 blows per foot. Using the Geopier elements, a nominal bearing pressure of 5,000 pounds per square foot was achieved, and the need for costly 50 to 60 foot deep timber or auger cast piles was eliminated. RIC provided a timely, economic solution for floor slab report without the use of traditional undercut and replace methods.
