Sunrise at Fox Hill Assisted Living

Bethesda, MD

Description

This luxury assisted living facility’s services include assisted living, memory care, independent living, short-term stays and coordination of hospice care.

Challenge

Borings conducted by GeoConcepts Engineering encountered a wide range of conditions from loose sandy silt fills to very dense disintegrated rock.  As a result, the bearing pressure provided by the unimproved soils ranged from 3,000 to 8,000 psf.  Areas of the building founded on fill soils required up to 8 ft of excavation and replacement.

Solution

Geopier elements were used to support footing and mat loads of up to 2,200 kips, eliminate the cost and time associated with fill/loose soil excavation and replacement, and control total and differential settlements to acceptable levels.   Over 2,300 Geopier elements, ranging in length from 8 to 18 ft, were constructed to support the six wings of the project.  Geopier construction was completed ahead of schedule and within budget.
