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?

I need to get a rough estimate of the off-site flow onto a project site. Are there free CONTOUR MAPS available on-line?

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?

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?

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?

Here is the attached file of the HydroCAD model.

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 /...
What about HYDROCAD VS. HYDRAFLOW???
I really like HydroCAD's modeling (more user friendly) as well as the look of the print outs.
Also, I just don't understand why the pond size required by the two programs would be off by a factor of two!
I had been using HydroCAD previously, but now I'm being asked with my new firm to recommend whether we stay w/ Hydraflow - that they had been using - or switch to HydroCAD. Hydraflow is now part of the Civil 3D software that we are using. However, there is virtually no tech. support.

The IBC 2003 code is in effect by the local government.
MSDS sheets state the following:

This is a paint storage room with the ability to mix some different colors in a closed mixing device. They sell the custom colored paint to automotive paint shops for their use.
The retail space is part of leased space in an existing strip mall. The existing retail space and strip mall does...
For a 10'x12' automotive paint mixing room (closed cap system), can we provide the one-hour fire barrier between this room and the retail space WITHOUT installing an automatic sprinkler system?
Also, how do you determine the "Fire Hazard Classification"?
