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

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...
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 /...
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"?
Has anyone used HydroCAD to model grate inlets or Catch Basins in order to verify that their capacities are adequate for a given storm event?
HydroCAD tech support keeps sending me back to the general support on their website.
I want to keep the model simple. I'm not sure how to deal with the...
I would like to purchase or obtain either a free or inexpensive software to design detention and retention ponds. The software should also be able to design the outlet structure, outlet pipe, orfice size and spacing, spillway, etc.
Software mentioned in a recent pond design seminar that I...
We have a development with a condo that is built on piles. Over time, the pile has had lateral drift. This has caused the wall to be offset from the top of the pile. In order to control the drift, we would like to install an anchor or strap at the top of the pile, then use a cable &...
I have a pre-engineered metal building with rigid frames. The manufacturer's engineer has stated that they always place the edge of the column footing flush with the edge of the building's turned-down slab. Since the column is within 8 inches of the edge, this means the column load is...
I have a small subdivision (less than 5 acres) and I need to design an onsite detention pond. Does anyone have any links to design guidelines for either hand calcs or an inexpensive software program? (Is SEDCAD good for detention pond design?)
