    Dewatering

    I am a SWPPP Preparer and also a storm water inspector. But first i will say read the project SWPPP they typically line out how to dewater the project. If not, i would read your state regulations for dewatering as sometimes there are exceptions to needing BMPS, say if you are only pumping over a...

    which depth to take for a basement footing for bearing capacity

    The problem is about a basement with footing 2' below the basement and to the top of the soil is 10' from the footing. Everyone is making this much more complicated then it is asking. The basement has 8' of fill on all sides and footing 2' below that. The bearing capacity is the soil resisting...

    which depth to take for a basement footing for bearing capacity

    ketanco I think when it comes to the lab they are referring to more in depth analysis of the soil and horizontal forces acting on the slab rather then the basic bearing capacity. If there was no slab then this would not really be a bearing capacity question it would be more of a pile question...

    which depth to take for a basement footing for bearing capacity

    I think to remember for the PE test, is that a lot of questions on the PE will try to cause you to over-think a problem and make you think it is more complicated then it really is. This happens easily with problems giving more information then what is needed. I took it a year ago, i can not...

    which depth to take for a basement footing for bearing capacity

    So it sounds like you have a building that has a basement that is 8 feet below the ground level. The footing is 2 feet below the basement. Why would you count the additional 8 feet when bearing capacity is resisting the vertical forces above it? In this case the building/basement is bearing down...

    Choose Construction or Geotechnical

    ketanco The entire test will have problems where you have to decide what information you will need to solve the problem. Some will give you every little piece of information possible and you may only need a couple of the values. Or they may give you little information and you have to dig into...

    Choose Construction or Geotechnical

    what ever you do in the afternoon does not matter. But remember that you will have specialized questions in each half. I did transportation and there were a bunch of questions out of the "Green book" (design book for roads by AASHTO. Construction is known as the "general" afternoon. Geotechnical...

    Base Course for Asphalt Parking Lot

    I have not heard of anyone use RAP for base but i know it is used in asphalt plants. You may talk you client into use the RAP in his asphalt mix and see what the requirements are with your DOT/City/Muni are for RAP since it varies from typical aggregate.

    Stormwater Management using Rational Method

    Most of the project i have dealt with were small sites (1 acre or so)and i used to rational method to determine the pre and post construction slows. Since typical flows must have pre=post construction for new projects. The critical time was used to calculate the intensities (in/hr)used in the...

    Stream Bedding Material Gradation

    in Alaska we have to take samples out of the stream itself and match the gradation of the existing stream bed. Simple and straight forward. that sucks to have to go through that testing. That is ridiculous.

    Using Base Course for Road Surface

    I would go with a chip seal or use a surface course aggregate as a wearing surface. I have not seen a base course used plainly as a surface course. I would think you would get faster then normal washboarding and form potholes faster. It would also not be as smooth of a ride due to larger...

    Crawl space for permafrost preservation

    where are you designing. I live in Alaska. I have not heard of this minimum. A lot of buildings are on stilts in areas with huge variance in the active layer (seasoning freeze thaw). We also use siphon tubes in areas to keep the permafrost frozen too. I think most of it has to do with insulation...

    Best Online PE Review Course

    I just took the PE in April (2 attempt). But IMO there were a lot of concept questions (non problem solving)these were my downfall the first time around. Best thing for me was reading my books and knowing the definitions and where to find stuff. I would say there were a good 15-20 questions that...

    Draining/limiting depth of lagoon to prevent flooding

    google earth is a tool but not very accurate, you dont know the distance between elevation shots.....I tried to export google elevations into Civil 3D and the the surface was way off. I had a steep grade and it was not shown on google earth because it had an elevation shot at the top of hill and...

    Stormwater Runoff in New Development

    Abuse permeable pavement has been around for several years, but its use depends on your location. Here in Alaska it is not used at all, in California where I was, used more often. In 2007 when I started to hear about it more and its use on parking lots.

    Stormwater Runoff in New Development

    abuse.....infiltration depends on what soils you have, you have a higher sands or gravel you will have high infiltration then if you have silts or clays. IF you are curious about how much could infiltrate (absorb) you can run a percolation test.

    Stormwater Runoff in New Development

    The underground vaults are great system and save a lot of space if you dont have it for a retendtion/detention pond. Look up StormTech, they produce a vault system.

    Minimum Turning Radius requirements

    I agree with all previous posts. Have you thought about incorporating drivable curbs and using something such as a bollard to project the lift station?

    Residential Development in "Pine Savanna" wetlands

    Based on the definition it sounds like it might be considered wetlands, but it is hard to because that description did list if anything is obligate wetlands or facilitative wetlands. But normally on wetlands you need to meet 3 criteria: soils, vegetation and hydrology. You can meet 2 and not the...
