Yale Steam Laundry Building 1 Condominiums

Washington D.C.

Description

A new 12-story, 133-unit condominium building next to the former Yale Steam Laundry Plant.  The original Yale Steam Laundry Plant was built in 1902 and added to the DC Historic Register in 1998.  The original building as well as the 120 ft brick smokestack were preserved.

Challenge

Soil conditions consisted of mostly sandy clay.  The column loads are from 40 to 1,300 kips and shear wall loadings from 740 to 2,900 kips.  The bearing pressure is 8,000 psf.

Solution

Approximately 343 Geopier elements were installed and range in length from 8 to 26 ft.  The Geopier system proved to be more feasible than other options evaluated including spread footings, drilled shafts, driven piles and mat foundations.  When compared to spread footings, Geopier elements were able to limit the differential settlement between adjacent footings while economizing the footing size.   Compared to drilled shafts, the Geopier system was more economic than the alternative of 80 ft deep foundations, and compared to driven piles, the Geopier system caused less noise and was more economical.  A mat foundation required a great amount of concrete and reinforcing making the Geopier system more economical.
