Looking for fill height tables for plain steel pipe. Pipe will be used as a casing.

Existing sanitary sewer main with approx. 12 feet of cover. Proposed project will increase cover to approximately 22 feet, which will exceed the pipes recommended maximum cover. Any recommendations on ways to exceed typical maximum recommended cover on pipes?

Any details available for or advice regarding a flow splitter? Proposed sewer extension needs to drain into two existing branches of an existing gravity sewer network. Flow must be split. Any experience with this?

Any good sources of design criteria (or suggestions) for grading a vehicular access for an ambulance at a medical center? I'm referring to the area where an ambulance would park while it unloads its patients and the manuvering area for the gurney. Maximum allowable grades?

Here's a link to a WSDOT discussion on the matter: http://www.wsdot.wa.gov/fasc/EngineeringPublications/Design/DesignClearZone.pdf It is also discussed in Chapter 4 of AASHTO "Green Book" under Horizontal Clearance to Obstructions.

Is there a function (routine, lisp, etc.) that will add up the lengths of selected objects? For quantity calculations it would be nice to be able to select a group of lines/arcs or pline and have ACAD sum the lengths.

It's been awhile, but from my past experience it was fairly common to improperly enter data using HEC2. (It sounds like your creating a "punch card" and running it through the program.) If you haven't used HEC2 much you might want to double-check your data entry; make sure your...

There will be some junction headloss, due to turbulence, where the two flows combine. I have a nomograph that was apparently prepared by Baltimore County Dept. of Public Works if you're interested.
