When I was right out of school, I worked for a company that was paying me a 40 hour salary and working me 70 hours a week. They billed the clients for all 70 hours.
I had a site contractor friend who didn't know about the NAVD88 vs. NGVD29 conversion. She built a site and then tried to tie into a road, coming in about 1.5 feet off. There was a lot to tear out and regrade to get everything to work. The problem is tying in outside the project.
My experience with assessing multiple military buildings of various ages indicates popularity of Tectum from 1950s through 1970s, probably highest in early 70s. I don't recall seeing its use after 1980. Sample size of maybe 2000 buildings built from 1950s through 2010s.
I recently learned that the largest cement manufacturer in my state (Florida) is now producing only C595 cement. This has been coming for a while, but only in the past six months has it become an issue.
Has there been any discussion of this on this thread? I don't recall seeing it.
What, if...
Also, who is the EOR? PEMB engineers generally will not be the EOR. If you're the only other engineer on the project, the client will likely be looking to you for this. You'll also assume responsibility for delegated design of the PEMB.
Yes, you should be at least 1 foot above your 100-year pond elevation. In some circumstances you should be higher than that. It depends on the outfall and surrounding topography.
It's not a code and it is very dependent on your location and hydrology.
The way I read your situation, the road needs to be at 11 to stay up our of the groundwater. I assumed that your FFE would need to be higher based on drainage patterns. Local codes are different. Your particular...
If the wetland is at EL 9, then seasonal high groundwater is at EL 9 or above. You need your base and subbase up out of the seasonal high. The road should be at EL 11 unless there is other information.
I would have an FFE at minimum EL 12, 3 feet above the wetland elevation.
