Where would I find typical concrete column tolerances for bridge column tolerances? These will be about 6' tall, rectangular in shape. Rail application.

Cool, thanks for the info. Maybe, I'll try it out.

Has anyone used or know of builders using EZ Flow pipe for perimeter foundation drains for residential applications? Supposedly they are becoming more popular, but I don't know if they work or not. Looks like they might pop out of the ground where there isn't much cover on them in rainy conditions.

Was thinking it might interfere with the cable movement when they are stressed, after the concrete is poured, but the more I think about it they probably don't.

Looked at a PT Slab and there is a no 4 rebar tied around the edge of the slab behind the cable anchors. They told me they do that to keep the anchors from popping out of the slab but it seems like it would limit the cable pull to just where the anchors are, but maybe there isn't enough bond...

Perfect. Thanks.

Anyone have a Hveem Stabilometer they want to get rid of? We are looking for one. Ele had to reverse engineer one and it is undergoing testing now but it'll still take a while till they start production. Thanks, Andy

Anybody have a good method to break down hard clay chunks into smaller pieces for proctor testing? We get buckets and buckets of clay chunks and spend a-lot of time breaking the clods up without damaging the particles by hand.

Can anyone help with finding a test method for neutral salts for cable/pipe corrosion testing?

Shutter would probably work. Have plenty of space for one. Garage wall is about 20' tall there.

IT's between a garage and laboratory... Frame was made to thin for the thicker 2 1/8" thick glass.. Would prefer not to have to rip the frame out since they just drywalled and painted the walls.

Thanks, Andy

I'm more of a geotech but have a question about a 4'x4' window in a 2 hour fire wall. 2 hour glass for an opening looks.like it is 2 1/2" thick. Is there any combinations of day 2 1-hour rates panes combined together, etc that meet IBC 2015?

Hi Folks, I am in need of getting a kneading compactor for soils only. Any recommendations as to which ones? All I can find is a kneading compactor from Cox and Sons or Instron for 60k+. Or if anyone knows of one up for sale let me know :) Thanks,

I'll calm down and look at the references you have given me. Thanks, I'm just at the end of my rope with this field right now.

I find it very disturbing that someone who doesn't even have a PE can force me to do something wrong. Guess I can always just say no, but I don't want to leave the client hanging either.

How do convince a hard headed regulator? All he uses is a manning's formula. So he gets flows way higher than I get and I don't think it is right for me to put a stamp on something that is wrong. Is there some research out there that says using just the plain mannings formula is wrong?

THANKS, I'll take a look.

Does anyone know of a culvert calculation procedure from the American Concrete Pipe Association on how to correctly calculate flows through a culvert discharging from a pond? I have a regulator insisting that I use the manning's formula which doesn't take into consideration inlet losses...
