Hello all - I live and practice in Oklahoma, but got my TN license to do some work for a client, but now that project is over. I'm considering not paying the TN PP Tax this year, as I don't forsee needing my TN PE license again anytime soon. Is this a bad idea? Do you guys pay yours, even if...
I’m wondering if anyone has any advice/suggestions/experience using petroleum coke in asphalt? I’m working with an environmental company to do some remediation work on a former oil refinery and we have a bunch of pet coke laying around. It would be awesome if we could use that coke for a bunch...
My current company provides geotechnical engineering recommendations and laboratory soils testing, but we do not have any field technicians or field testing equipment. In the past, I have worked at places that provide both. Is it up to the geotechnical engineer to run the proctor analysis on...
This is for a new health center in an open field. We've done land surveying for this architect before. He is asking for a topographic survey (no problem), but also "civil engineering". He has already told me that another firm is doing the geotechnical engineering (which probably means that...
In the formulas for oversize correction, are you supposed to use Bulk Specific Gravity, or Bulk Specific Gravity (SSD). What does Bulk Specific Gravity (oven dry) mean? (is over dry equivalent to SSD?)
Thanks.
A client has asked me to come up with a mix design to bring his site's red clay's PI down from 22 to between 5 and 18. He said that in addition to bringing me a sample of the red clay, he was also going to bring me some "lime" so I can run whatever tests I wanted to run. I thought he meant...
Yeah, all of the members shown in my drawing are of the same material. The client specifically asked for it that way hoping the handrail (actually made of the beam material) would be able to counter deflection. I don't think it would help, either. Here's what my structural engineering friend...
Assume there is no slip and that the handrail is the same type of beam as beam a. The left side of the handrail is affixed to the wall, as is the left side of beam a. the right side of both the handrail and beam a are attached via another similar beam to the back wall (I forgot to draw in the...
I am designing a catwalk for a customer but there is too much deflection in the beam supporting the walking surface (beam a). The client argues that the handrail provides two additional support points against deflection, but I disgree. Does it help? If so, how do I calculate the amount that...
I am trying to measure the Heat Release Rate from some burning mattresses as per ASTM E 1590-07. I have my fire room set up with an exhaust hood in the ceiling and fresh air intakes in the ground (to draw the exhaust up into the hood). Attached to the hood is a long exhaust pipe with a fan on...
