Im working on A school in SanDiego CA, that happens to be built out of wood. Its two story and has 6x6 posts just about everywhare. My question is what are the rules for drilling. Can I drill A 15' tall 6x6 post that helps carry A beam that supports the second floor. I checked the detail on my structurels plans and it gives no details on drilling and notching. The on site inspecter wants me to RFI but we all know how long that could take. Is there A general rule of thumb or A place to referance.

i think thats up to the building inspector...and i know theres a rule of thumb on non- supporting joists...but on that id do what the inspector wants
 
I'd really wait for the RFI.

I wanted to rattle of some building specifications of boring in wood.

Think of it this way you should replace what you take out of the structure.
Now lets see, how do you do that? You get it engineered, or get a release, either / or, Ok both.

Doesnt matter how long it takes. You better have it in writing from the engineer. If you go drilling into these post you need clear direction on where and how big of holes or notches you can make. If any thing happens to this building the blame game will start and if you do not have it in writing then the fingers will point in your direction.
"School collapses due to electrician drilling a 1/2" hole in 6x6 post although the airplane that crashed into the school may have contributed to the collapse"
 
tackmaster, The on site inspector has given you some good advise. Let the Engineers' do

the telling and you do the listening, that way if a problem arises it is not 'your' problem.

A RFI won't take long if you tell them you are at a standstill until the info arrives.
 
Sounds like post and beam which is not covered under the IRC. Since it is a school, it is not IRC anyway and gets bumped to the IBC if that is what your jurisdiction uses.

Since it is commercial, these items such as notching and drilling should have been spec'd out by an engineer.

I always use the "every day it takes to get an answer, is a day added onto the completion date of the job." It seems to motivate them a little since there maybe a penalty clause in the contract. :grin:
 
Here is something that may help you, it is not quite for 6x6's but I would think you are safe applying the ratios they use to any size lumber. Ok it won't post right......pm me your email I'll mail it to you.

I'm not sure I would agree that you would be safe applying these ratios to a 6x6 post. The diagram in question is referring to studs, which are repetitive members where the load is spread out on all the members. This provides an extra margin of safety you don't have in a post.

Cheers, Wayne
