GMU provided a comprehensive foundation investigation for a 19 story steel moment frame office building with basement adjacent to two 4 level partial subterranean parking structures. The 19 story tower is supported on cast-in-drill hole pile foundations and structural slab. One of the two parking structures is founded on conventional spread footings while the other structure which is founded on old fill is founded on CIDH piles. The project also includes large underground percolation systems as well as a service yard and other improvements.
