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...
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...
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.
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...
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...
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...
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...
HI,
I have a two part question concerning concrete flared end sections.
1) Does a flared end section increase "inlet control" intake?
and if so,
2) Does anyone know where I can find, either formula's for calculating a fes's inlet control capacity or a set of nomographs with which to...
Hi,
I'm designing a tightly spaced mini storage building site and would like to make sure that, at a minimum, a truck with a trailer could maneuver through the site. Does anyone know where I could get any cad templates to help with my design. I have the templates in the Green Book but thought...
