Hello Everyone,
Is it expected for a design engineer to remember everything off the top of their head for a 1,000-page set of contract documents? I am the design engineer in question being asked questions at progress meetings, but often I don't recall the exact procedural language or spec for a...

Hello!
I am looking to get some advice regarding a mobile hand railing system possible weak point. I've been asked to look into creating mobile hand rails to act as sign mounts. These mobile hand rails would be moved on occasion to different locations as needed. I created two designs due to a...
Hi All,
So I've noticed a lot of local building codes lump free standing masonry walls and fences together in some of their regulations such as requiring engineering when going over six feet in height. Is there some language in the IBC that defines a masonry wall as a type of fence? Are all...
Hey All,
I have some questions about licensing exam scoring:
1. Do employers know an examinee's scores before the test taker does?
2. Can an employer effect an examinee's score?
Just wondering.. Thanks.
Hello All,
I'm in California and I am looking for the references regarding the rules for a design storm event in Southern California. I know there where to find the design storm events for capture and treat BMPs, but before those regulations were implemented I'm sure there were regulations out...
I have seen and heard of many professionally engineered projects fail like the recent bridge collapse in Florida; Many licensed engineer projects that fail become case studies. I am not saying licensing is a bad and pointless regulation, but I would not say that licensing makes an engineer...
Hi all,
Is it actually a thing for engineers who went to school to discriminate against licensed engineers who never went to school? I have a friend whose father never went to school, but became a licensed civil engineer. She told me that engineers who went to school would give him crap for...
Hello All,
The Caltrans highway design manual recommends a minimum thickness on road overlays to help resist cracking. Indeed the idea behind "superpave products" is to make a long lasting road by increasing the Asphalt Concrete section. What I am looking for are reference standards to support...
Hi All,
Anyone know where to start looking for estimating water use for dust control? Is there a rule of thumb for the amount of water used per square foot of disturbed area per day?

Hello Everyone!
Has anyone been successful in not implementing a Caltrans Retaining Wall Type 1A into their Bioretention Basins structures as a sort of separation barrier between the bioretention basin and existing soil material? Although my local NPDES district seems to consider a 1 foot...
I see bioretention basins installed in various places around where I live in Riverside, California. Are you referring to storing and treating water on individual residential lots? If so the only thing I see that most likely partially treat the water sources is a grass swale in the front yard...
Hi All,
Currently I am working on a construction estimate for a bioretention bmp systems. An aspect of a bioretention basin is the construction of a perimeter "retaining wall." I am using the BNI General Construction Cost Book to obtain cost data for said retaining wall. My question is if the...
Currently I am working on getting the drawdown for my bioretention basins below three days. The controlling factor seems to be the infiltration rate of whatever soil mixture I use. Now realistically I know the best soil type I may ever get is 5 to 6 inches, but this won't allow me to drain the...
For form release / oils or bearing axle greases are there any recommended brands? I realize I may not have the same exact brand available in my area, but I could use to the material for a comparison for what is around me locally.
In good humor I curse ACI / ASTM for not having a standard on...
So I am designing a concrete pad via ACI360. For a unreinforced concrete pad it recommends dowel rods at joints with oil used as a bond breaker from the concrete. I have searched online for a standard on what type of oil / epoxy / sleeves to use, but nothing is coming up.
Can anyone point me in...
Great reference cvg! Thank you.
Ultimately the decision to grout the entire length of culvert is not mine. The culverts go through a landfill termination plug and were designed to be temporary so as to allow surface run off to exit the "bowl." We want to avoid any void spaces behind the liner...
