    Another "what would you charge" post

    It sounds like $40/hr is about right. Given that I'm still getting up to speed on the local regs, $35 is pretty fair. I'll probably up my rate to $40 at the beginning of 2014 if we're still working together. I don't need this work anymore, so it needs to be worthwhile to me to continue on...

    Another "what would you charge" post

    I should also add that I don't seal anything or take responsible charge for anything. I also don't buy my own insurance.

    Another "what would you charge" post

    I currently do side work for a one-man land development engineer as a contract / hourly employee. No benefits, insurance, etc. My real job handles all of that. I do the stormwater calculations for the sites he is working on. I'm a PE for about 10 years now. I'm new to the geographic area...

    Engineering Consultancy as a Second Job

    I work a 40hr/week government job, and do side work for a land development engineer on a contract (hourly) basis. I provide my own computer. The guy I work for provides any necessary software. I don't seal anything so I don't have insurance (yes there is risk associated with that). I charge...

    How do you represent a headwall in Stormcad?

    I googled, and looked around on the Bentley forums to no avail. As far as I can tell, there's no elegant way to model a headwall in this program. (Often, I have a headwall intercepting channel flow at the top of a storm sewer system.) I used a no-loss, 100% efficiency catch basin, with rim...

    Automatic "C" calculation in StormCAD?

    I just started using Bentley Stormcad after coming from Hydraflow for storm sewer analysis. Is there any way to define areas of cover (impervious, lawn, etc.) and have Stormcad overlay those with each catchment area to automatically generate a weighted C? I find that deriving the runoff...

    Utilization / Billability rate?

    The ratio of billable hours to worked hours required by your company? Also include your title and industry. Me: 81%, Civil Engineer Project Manager, Consulting Engineering Company

    Pavement Base Drain; Where?

    Is there a black and white rule for where to install base drain? Is it from PC to PT on any sag curve where the road is in cut? Is it anywhere the road is in cut?

    Parallel Storm Sewer System Modeling?

    I have an existing storm sewer that I want to leave in service, and supplement with a proposed storm sewer. The two systems will intersect at several points to equalize flows. They do not follow the same route over a length of about 5000 feet, so I can't just treat them as one pipe. My...

    Engineered soil for controlled infiltration in basin?

    I have a project in an area underlain by limestone. I want to control infiltration rates within my basins and other BMPs, but not seal them. Can anyone point me to a resource which will help me design a layer of soil to line the basins that will control infiltration? Are there any...

    Resource / Manual for on-lot septic design?

    Thanks folks, I'll look all of these up.

    Resource / Manual for on-lot septic design?

    Is there an "aashto green book" of the septic tank world? Any resources where I could do some self-study, or is septic design all learn by rote?

    Effects of Tc and Tt on SCS hydrographs?

    I read part of the HydoCAD manual today that deals with unit hydrographs and TR20. It was a good overview.

    Dividing Offsite / Onsite DAs. SCS Methodology Question

    I tried it two ways: 1. Two subcatchments with identical Tc. One for onsite and one for offsite. Both subcatchments pointed to a reach which was Study Point 1. This configuration produced about a 10% higher flow rate than method 2. The peaks of the runoff hydrographs were slightly off in...

    Effects of Tc and Tt on SCS hydrographs?

    "Travel time may be included in the Tc, or handled as a separate routing operation, depending on the methodology and layout of the watershed." Can I take this to mean that if your watershed is only divided by a property line, it would be conducive to including travel time within the Tc? If the...
