fel3, Thanks for the great reply, although I did not follow your formula, what is r?

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...

Thank you for the great explanation.

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.

Thank you guys. All helpful tips. CVG, Can I ask how you calculated the ENR adujustment (1.38 in this case)? I could not find it on ENR website.

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.

@MiketheEngineer, It is almost impossible for everyone to miss one question. So, I don't think re-score everything is the option, there. I think the link that BridgeEI mentioned says that there is no minimum qualifying in each section, which is what I was hoping to find out and was kinda...

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!

I am sorry for my reply there!! Its supposed to be my question to the forum :) sorry about that.

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?

Thanks RWF7437 and others. I did talk to the local flood control and they said the request should be called LOMA not LOMR. They also said they do not distingiush between LOMR and LOMA anymore, since flood control started looking at them with no difference (This request is to remove ZONE A...

Thanks for the responses. I have mentioned to the engg. that he should apply for CLOMR not LOMR. This was his reply "This LOMR application is for the removal of the FEMA Zone A from a portion of the existing site. A Special Flood Hazard Area(Zone A) can be removed from a parcel of land if it...

Thanks for the responses. My firm is doing the review for a City as a consultant. The City is going to make the decision based on our input. I do not have lot of experience dealing with floodplain/FEMA issues, but I have learned quite a bit in one day. This is a great site for young engineers...

Hi everyone, I am reviewing a LOMA study. West half of the proposed site (residental, almost 450 acres)is in Zone A (special flood hazard area inundated by 100 yr flood where no base flood elevations determined) and the east half is in Zone C (minimal flooding). The engineer is proposing to...
