Hi all, I am working on a project where I am trying to calculate gpm from each building(SFR, Condo, Restaurant, Hotel, Bar etc) and convert to cfs to size the sewer lateral for each building and sewer main lines on proposed onsite streets to finally calculate total sewer flow rate from the...

Guys, Can some one enlighten me the difference between design and construction center line. I am working on a street improvement project, and this came up in the kickoff meeting. I am kinda new to the street design. Thanks.

Hello, I am working on an prelim. engg. estimate to find construction costs associated with relief drain tunnels. This drain is going to be 6 miles long, 36' in diameter and probably 50-100 feet deep. In my research I found similar utility tunnel projects and the costs associated with them. My...

Hello All, Can someone please explain to me what a Hinge Point is in Street/Highway Design? Thanks.

Someone please help me understand the curve data of a curb, plz? Curve data #1 R=10' L=15.85' Delta starting angle 36deg 28min 57sec end angle 127deg 16min 52sec total angle 90deg 47min 55sec what delta should I use to calculate my Tangent length T= R*tan(delta)/2 Also, what is T and...

What is a transverse line? Is it a solid white stop bar line? Is there a diagram somewhere that explains what a transverse line is? Thanks in advance!

What design storm would have higher peak flow rate in general, Is it 100 yr 24 hour or 100 yr 2 hour event?? thanks

How do you determine the lengths for sheet and shallow flows in a watershed? How do they vary in different areas, say, mountain regions, desert lands and pavements?Is there a standard rule of thumb or depends on watershed characterstics?
