I have seen simple and more complex calculations for the checking the stress from roof framing to jack studs. My question is: Can you use simply the Fc (compression parallel to the grain) allowable stress and compare to the fc = P/A? Or is it necessary to compute Kce, Cp, etc. for the more...

Thanks for all of the posts and feedback. Drumchaser, this is an existing ASPHALT parking lot. The larger pothole areas indicate a very thin (1.5" - 2") asphalt directly on clay (no gravel or crusher run sub-base). So, I guess milling would not be an option, is that correct? Would recycling...

If an existing parking lot for a private ambulance service has a lot of chuck holes and broken pavement areas, is it feasible to clean the loose debris and then cover the entire lot with concrete? The parking lot has approximately 50% of the total area with broken pavement that needs either...

Thanks for the links. I can't seem to find any free download. It wants me to order a map for a fee. I guess that is the only way to get a topo map on-line - to pay for it? ("You're only as old as you feel." - Satchel Paige)

I need to get a rough estimate of the off-site flow onto a project site. Are there free CONTOUR MAPS available on-line? ("You're only as old as you want to feel." - Satchel Paige)

Great information! Thanks for the feedback!! ("You're only as old as you want to feel." - Satchel Paige)

Would you have to run some non-destructive tests on the parking lot to determine the condition of the existing pavement? What if the client's budget is real tight? Are there some reasonable assumptions that could be made to develop a recommendation for repairs and overlay? ("You're only...

Is this on the wrong forum? ("You're only as old as you want to feel." - Satchel Paige)

What about the surface repairs and new topping layer thickness? ("You're only as old as you want to feel." - Satchel Paige)

I have a project with an existing asphaltic concrete parking lot. The parking lot has several cracks in it as well as a recently cut trench for a water line installation. The trench has some soil fill material that was placed in it to cover it up, but it has not been covered with asphalt or...

How do you model a vortex valve in HydroCAD? Are they very expensive? Are they very common? ("You're only as old as you want to feel." - Satchel Paige)

Thanks for the help! I will try those various options. ("You're only as old as you want to feel." - Satchel Paige)

The target outflow rates are: For 2-year: 11.46 cfs For 25-year: 29.40 cfs So, since the 2-year event is discharging through the emergency spillway, I need more pond volume, correct? "You're only as old as you want to feel."

Here is the attached file of the HydroCAD model. "You're only as old as you want to feel."http://files.engineering.com/getfile.aspx?folder=6d8a236d-24be-45ed-8f32-fe60577d244f&file=Windsor.hcp

I used the HydroCAD sizing feature for ponds to get an initial estimate of the pond volume required (using the pre-developed 50-year runoff flowrate). Then I set up my model to reflect the post-developed flow (Subcatchment) routed to the pond and then routed to a Reach (the receiving basin /...
