House Bolting, Foundation Retrofit, Cripple Wall Bracing

Some Examples Of Jobs That Have Been Done Incorrectly

Improper nailing pattern for plywood shear panels; sill plate blocking was not installed prior to plywood installation. Note the lack of perimeter edge nailing at the sill. Also note that ordinary "plywood was used on these short 4" cripple walls. Four inches is insufficient room to properly install the required blocking, therefore another critical aspect was ignored by this "community minded" contractor who is always on the job to see that the customer gets his moneys worth.
This view shows additional evidence of disregard for required cripple wall bracing.

Note the absence of required blocking and hardware.

Note that there is no method of connecting the upper plate to the foundation.

This picture shows improper edge distance for foundation bolts. The bolts were drilled at an angle to avoid block material under the sill plate. Also note additional improper nailing and lack of shear transfer at the panels above the foundation.
Tightening down the bolt.
EAGLE ROCK:
Inserting the metal framing anchors to connect the sill plate to the rim joist.
This photo highlights the absence of connectors which would be required in the transfer of earthquake loads to the anchored sill. Interesting that this contractor postures himself and his wife as a community minded team dedicated to safety for senior citizens, schools, churches, zoos, and animal shelters. He further boasts that unlike other contractors he oversees all of his work. These photos are the documented results of his personal touch.
Contractor properly installed plywood, vents, nails, and blocking for this cripple wall. Any investigator should ask why does contractor omit required joist blocking and framing anchors above the plywood?
Why would this contractor brace the wall in the photo above and then leave these walls unprotected? Could it be that the work space in this area of the home was difficult? Who would suspect that the good contractor would leave this work out just because it is hidden from easy viewing?

"Seismic Safety bolted my house and adjusted the floors. I had no qualms about having them back in August of 2006 to build the foundation for my new addition. Because of their attention to detail and pride in a job well done, Seismic Safety is on my short list of contractors I recommend without hesitation. I look forward to putting these sentiments on Angies List."
