    Subgrade Optimum Moisture Content

    I'm overseeing the construction of a road which has required a 2' undercut of the in situ soil. The 2' undercut is being replaced with engineered fill which is a gravelly clay and is being placed in 8" lifts. The proctor that was performed on this engineered fill indicated that optimum...

    Storm Inlet Box Construction

    Ryb01 - The specs and details call for a standard cast in place structure. This is for a private development and the contractor and owner are trying to reduce costs. I work with the City and, since this is a private storm system, I have some influence on whether they are permitted, but not the...

    Storm Inlet Box Construction

    The timing of that is funny and that's the exact kind of issue I'm concerned with. I can't see any reason to allow CMU walls. I mainly wanted to see if anybody had any knowledge about them that I was missing. Thanks for the response!

    Storm Inlet Box Construction

    I am working with a contractor who is dead set on using CMU blocks to construct his storm inlet boxes instead of casting the walls in place with concrete. He will put rebar in the CMU wall and then fill the interior of the wall with concrete and vibrate. The top and bottom of the box will be...

    SDR vs C900 vs Schedule40

    Can anyone explain the history behind the developement of these three types of pipe specs(sdr/c900/schedule40)? I understand the difference in dimensions, I'm just curious about the development of each or more specifically, why there are three types that are commonly used.

    MicroStation J (Ctrl+I)

    Go to -Settings-DesignFile then select the working units tab and at the bottom there should be an option to choose between bearing/azimuth/conventional. Don't forget to go to File-SaveSettings before you close file to keep settings

    Thanks for the link - it appears to be a quite useful utility.

    Points file format

    Hi- ok, this is a basic question but I don't have a lot of experience in surveying. What is the difference between a .crd file and an .asc (ASCI?) file? Is it just formatting? Is there a way to convert between the two? The situation I'm in, is that I've always used Microstation and EaglePoint...

    HEC-HMS Issue

    Hi, I'm modeling a detention basin in HEC-HMS using the reservoir function. The reservoir has two drainage sub-basins flowing into it. There are three culverts and a spillway acting as the outlet structure. I've entered the reservoir data in the elevation-storage format. For the tailwater...

    SCALING MULTIPLE OBJECTS

    namdac, Thanks for referring me to that website. It was my first time on there and I did find the mdl that you were referring too which worked well. Thanks again. Also I didn't explain my situation very well. What I had was, in the base drawing(1:1) several cells(labels) which were placed at...

    SCALING MULTIPLE OBJECTS

    HI, I have a situtation where I need to scale up several (50-100) objects but need to keep each of the objects the same distance apart as before so i can't use a fence or group the objects because this will scale the distances between relatively. Also, each object is different so I can't just...

    Cross Slope across bottom of storm box?

    Thanks for the response. I just graduated a year ago and the PE who i'm interning under doesn't think the .1' drop is necessary so I hadn't ever heard of it though it is logical. I really wanted to see how common of a practice it is and it sounds like it is quite common. Thanks

    Cross Slope across bottom of storm box?

    Hi, Does anyone have suggestions for the minimum cross slope across the bottom of a storm/junction/inlet box? I guess I've just never considered it before until my surveyor, who's about to do the construction staking, brought it up. I've always performed the pipe design assuming the slope to...

    raster images problem!!

    Hi, You might try to adjust the "update sequence" which is an option in the raster manager underneath the settings menu. The list that is shown is the list of references or raster images attached to your file in the order which they are updated. Your current file should appear last on this...

    FES's Effiency

    Thanks for the direction. The engineer who reviews plans for a city I work in has recently required that all culverts be able to accomodate the 100-year storm without overflowing into the street. As a result I wanted to make sure that I was getting every bit of effiency out of the culvert as...
