Question: I have a question I was hoping you could help me with.
Regarding type 1B pole foundations (straight pole, 4.5” OD) We noticed
that California recently updated their requirements on 1B pole foundations,
making them much deeper and complicated. The requirement used to be 3’ deep
with J-bolts, now it’s 5’ deep with an anchor plate. I was wondering if
you knew anything about this or could refer me to an “expert” in this
area. See the attached new requirement. Thank you, I appreciate your help. We sell a lot
of these and just trying to figure out what we should to offer.
Answer: The plan you sent is valid. You can find the whole set
of plans at
http://www.dot.ca.gov/hq/esc/oe/project_plans/HTM/stdplns-US-customary-units-new10.htm#electrical. Please be sure to check your
contract documents before you jump on the new plans, though. Each project
should have a statement about which year of Caltrans documents were used as the
basis for design. If things are typical, it will be a gradual transition
over the next couple years from the 2006 set to 2010.
