    Washed crushed recycled concrete

    Hi: We have designed a porous asphalt pavement parking lot with 3-ft +/- thick stone reservoir beneath. We have had several constructed projects constructed with clean No. 2 virgin stone aggregate and they have worked and held up well. We have had a contractor propose to use recycled concrete...

    Catchbasin Invert

    Hi. I thought I posted this before, but perhaps did not do it right, so I'll try again. Quite some time ago I was sitting in my car in a VERY heavy rain. While waiting for the storm to slacken, I observed a series of inlets on a steep street. Water was erupting from each inlet and actually...

    Manning roughness coefficients for Grass lined creeks

    "n" varies, depending on the length and stiffness of the grass and depth of the water. And the depth of the water will vary depending on the length of the grass. Sounds like a conundrum, Grasshopper, no? Just kidding. Anyway, you should design or analyze a grass channel using the...

    cracks in Masonary walls

    You say the problem is near the stairway. As I do not know the configuration of your construction, this is speculation, but it may be useful in identifying the cause of the cracks. Is the stairway supported by any portions of the walls. If so, that portion may be loaded heavier than other...

    Duties in municiple/public works

    Aside question to AggieCE...I am just wondering, is Aggie short for Agricultural student? Just wondering because my first degree is in Agriculture (before attending and graduating Civil Engineering school) and students with other majors called me Aggie. That would be rather uncanny that two...

    Excavation/shoring in deep sand

    You didn't say the depth of the foundation next to which you are excavating - and whether or not the excavation could be done in smaller segments or if it has to all be opened at once. The effects of the adjacent foundation, depending on its depth, should also be considered and how close you...

    Troxler errors in an excavation

    I worked for a company in the 1980's and no matter what field work you were going to do, you got certified for it. We won a landfill liner bid - so my company said we are going to use a troxler - who wants to take the course and get certified. Ask Troxler - I am sure they can offer some...

    What about photogrametry?

    There may be some interesting and hopefully useful related information at the National Geodetic Survey (NGS) website, mostly regarding survey and the control points that the Survey maintains and into which most if not all photogrammetric work is tied. The National Geodetic Survey develops and...

    Rip-Rap: Energy dissipation calculations

    Hi Wterguy: Hope this isnt too late (probably is). At least it may be helpful on the next one. The USDA, Soil Conservation Service has all kinds of information on rip rap, conduit outlet protection, etc. They have nomographs and charts. I dont know if your application will fall within one of...

    Stormwater Sediment Seperators

    What state are you in. In NJ we have very stringent design standards for storm water management. Soil erosion and sediment control plan during construction. Many instances post-construction management requires detention of 1-year storm to 50% of predev discharge (generally requiring outlet...

    Anchor trench design

    Hi: I would consult a few manufacturers, regarding anchor trench need. Maybe Gundle and others. Do a Google search, if you need manufacturers names. They sell it and would surely know what applications do and do not need a trench. I am sure they have data on soil interface friction. Also...

    Duties in municiple/public works

    I'll add my 2 cents. I generally saw two sides to municpal work in which I was involved: 1 - capital improvements - municipality hires contractor to build road, sewers, water distribution systems, landfill...whatever - keep civilization as we know it running. You design it - they build it -...

    cracks in Masonary walls

    Is the crack uniform in width or is top wider than bottom. Shrinkage would probably not be so serious as differential settlement. What can you say about the foundation on which the wall is constructed?

    truck turn templates

    Hi CSainte: How have you made out on finding hard copy truck turning templates. Since they need to vary for scale and truck. we have several which we xeroxed from various DOT or design charts. There are various films that work with copy machines. If you email me at my work: whna@fast.net I...

    An Ethical Question (plan stamping)

    JAE. How much of a repeat client is this? I hope they are not a repeat client because you do the extra "right" work on your own time. Such a situation would be externalization of their rightful costs on to you. Ethically for them a no no. Business-wise and re: get a life issue, a no...

    info for trench shoring design

    I used to do alot of pipe installation and shoring for installing groundwater treatment systems and digging out oil contaminated soil in close proximity to buildings - often there was no way to cut back sides. I found renting hydraulic shoring useful for the pipe installations; it was light...
