    Dual Hydrologic Soil Groups

    How should I run a dual hydrologic soil group (A/D) in TR-55? It appears the soil group is defined A/D due to the shallow water depth, however, still has drainage characteristics of an A soil. Should I run it as all A soil or 50% A / 50% D?

    Overtime

    How's overtime typically work with the firms you work with? I currently am a civil PE that works for an A/E firm and a majority of us are salary. We're overly busy with too much work right now. We are not paid for overtime, so I generally do not work overtime unless it's necessary (i.e...

    Engineering Proposal Estimation

    When creating proposals for projects, we've typically used $1500 per sheet as a cross check on our prices. Does anyone use anything different? We use standard 24x36 sheets. Thanks.

    Change Order/Credits

    When a contractor applies for a change order, overhead and profit are applied to their extra. How about when they issue the Owner a credit? Shouldn't the Owner receive the overhead and profit associated with that item as well? Has anyone ever done this, seen it done, or seen it explained in...

    I'd like to see some experiences and opinions on the following question. What is the maximum distance a septic tank should be placed away from a building while utilizing a 4" SDR-35 pipe with 1/4 inch per foot slope? We haven't encountered any maximum distances before and New York State...
