Solid Foundation for Grain Storage

Solid Foundation for Grain Storage

URETEK ICR was contacted regarding settlement in two identical 1.5 million bushel grain flat storage buildings.   The overall structure dimensions were 600 ft. long by 135 ft. wide with a Quonset style roof . Below the floor of the storage buildings, a tunnel with conveyance system and a series of aeration tunnels were installed to facilitate moisture control and grain transport.

New FHWA Manual on Spread Footings for Highway Structures

March 22, 2010 rockman Comments Off on New FHWA Manual on Spread Footings for Highway Structures

Selection of Spread Footings on Soils to Support Highway Bridge Structures Hot on the heals of the revised MSE Wall Manual, the FHWA has released another manual, this one on Spread Footings. Selection of Spread Footings on Soils to Support Highway Bridge Structures was authored by Naresh C. Samtani, PE, PhD, Edward A Nowatzki, PE, PhD and Dennis R. Mertz, PE, PhD. So what is this manual all about? I think the foreword by Scott Anderson, PE, PhD of the FHWA Resource Center says it best:

City of Chilliwack, British Columbia to Pay $18M for Up to 42 Homes On Landslide

October 12, 2009 rockman Comments Off on City of Chilliwack, British Columbia to Pay $18M for Up to 42 Homes On Landslide

chilliwack_bc_landslide_neighborhood The Chilliwack Times reports that the City of Chilliwack will pay 80% of the assessed home value for up to 42 homes in an Eastern Hillside subdivision that are located on a slow moving landslide. The issue was first noticed in 2001 and several homes have had significant damage, but most are currently undamaged. The City denies any responsibility, but it’s legal counsel recommended a settlement. (Photo by Paul J. Henderson, Chilliwack Times)

Normally the geotechnical engineer for the subdivision would be held accountable. But apparently the slip surface is located 30-m below grade, much deeper than borings for a typical investigation for a subdivision. I wonder if there were any geologists consulted? Click through for a Google map view of the area and you can do your own armchair photogeology quarterbacking! Your heart does go out to the people losing their homes, they had no idea. But it could be worse, they could be in La Jolla and be getting squat.
