rotary laser level - Contractor Talk - Professional Construction and Remodeling Forum

I need to shoot grade with a rotary laser and have never used one. I need to dig for a foundation wall and want to go down 44" from top of existing foundation for an addition. how do i go about using the laser to achieve this depth accurately?

General Contractor??? Digging your own footers and you don't know this?

You'll find you won't get very good advice posing as someone you're not... or, posting a question that the average GC should know without an introduction.

And don't double post!

Do you know how to do this with a builders level or transit?

If you do its the same with a laser.

This is really layout 101 my 16 year old son poot with his considerable skills knows how to do this. you cannot know what you are doing and therefore should not be here go to the DIY site. Thank you very much and good night!

Wow, I am suprised by the rude response. Give me a email address and ill send you plenty of pics of my work. i have never use a rotary laser before and have never dug my own footings before. i am a framer and a general contractor. i usually sub out excavating and concrete. it was a legitimate question that i needed an answer to. im sure before you became the big shot builder/remodeler you think you are that someone explained some things to you. im sure you had questions from time to time. thanks for the help.

He's right, have you never used a transit?

What the F**K is the difference between a rotary laser and a 4 foot level. OK one shoots a cool light and one doesn't. they are both levels and the only difference is one reaches farther than the other. everything else is the same pretend its a 4' level and do everything like it was that and it will work out if not then you really don't know what the H**L you are doing and that scares me.

eric131 · 05-18-2009, 10:23 PM

no ive never had to use a transit

Measure down from the reference line projected by the level. If that is not enough information, you are in over your head. I'm not being rude, I'm being truthful.

This is the absolute truth and Loneframer is in a much better mood than I am.

A man's got to know his limitations.

It's one thing if you're learning on your own house. Quite another if you're gambling with someone else's.

If you really were a framer, or a carpenter you would know how to do this. Carpentry 101

Let me see
Overqualified for every job I have applied for
Out of work for almost 6 months
Spent 35 years in residential construction and can't get an interview doing commercial which is the only thing shaking around here but you need a top secret clearance to do it.
Way too many MORONS here today that can't figure out a basic offset problem and call themselves General contractors.
That would be the short list

If you are a framer, how did you check the foundation before you set the sill plate and framed the floor system.

I hope you did check to see if it was level and square, because they usually are not.

Hey
I thought this was a forum, not a put down. Hope some day you guys may have questions, even if simple ones, and can get the answer without all the c___p

OK, you have good reason to be grumpy, I hope things get better for you. In the meantime enjoy handing out the beatings, I for one enjoy the carnage.

katoman · 05-18-2009, 10:49 PM

Yes, this is a forum for tradespeople. The guy claims to be a general contractor and a framer (carpenter) and he doesn't know how to determine excavation depth? Give me a break
