Road building in a hurry MASSIVE Road Rebuilding Pensacola, NC USA STRONG!🇺🇸 GloryBee Oct 24 2024 Some seat of the pants engineering going on here sometimes it is worth risking a need to do over better to get things moving now.

The color scheme contract could stand some adjustment, some - not all items have such low contrast that it is difficult to read. Features that at first seemed to be missing are starting to work, look under the three vertical dots. There are some features that will be improved when some...

Engineers are frequently called into "Root Cause" investigations which only get as far as finding blame. Us engineers need to understand how much this wrongheaded approach hurts the working environment. Brady Heywood investigated all fatal accidents in Queensland mines and quarries from 2000...

Miles of serious scour damage to railway roadbed. Geological Transformation in the Nolichucky Gorge ~ Before and After Helene, Designs in Orbit, Oct 22 2024 CSX roadbed on rock scoured away.

A local report with some additional shots of the post collapse condition. Sapelo Gangway Damage Minorcan Mullet Oct 22 2024 Image from video above. Definitely a sideways kink in the handrail, close to the sharp bend in the walking surface.

Whatever coating you end up choosing, DO NOT skimp on surface prep. You could scan the Forum List Try Paint Coatings Engineering

A quick search turns up 2 incidents. The first one links to some information regarding maintenance and operation of concrete silos used for silage. It is reported that improper filling can cause non uniform radial loads on the shell which can result in shell failure. April 27 silo collapse in...

Texas got 42 inches due to a NOAA reporting station (https://forecast.weather.gov/MapClick.php?lat=29.4238&lon=-95.2441) being at the location of the record rainfall so it could become part of the official record. 42 inches, set in Alvin, Texas, on July 25-26, 1979, when Tropical Storm...

Making a map of a buried earthing network is possible using underground utility location equipment that includes a signal injector. The locator operator marks found items on on the ground with marker paint, and a surveyor follows and makes a map of all of the marks. In my part of the world this...

NOAA Atlas 14 Precipitation-Frequency Atlas is one input to the FEMA flood maps. If you delve into the technical underpinnings of the Precipitation Frequency Atlas you will find that an attempt to include the impact of orographic lifting was made, and recognized as imperfect...

I doubt the FEMA appeal process is useful for identifying the possible extent of Riverine Flooding similar to what occurred in Haleen. See attached, the standard mapping line for the extent of Riverine Flooding still uses a base flood line of 1-percent-annual-chance flood elevation (100 year...

Conditions on the ground This is a collection of videos on the aftermath of Halene on the Toe river at Green Mountain NC. DAY 7: ATV ride in the Helene warzone that was our neighborhood. Green Mountain, NC At this point some roads have been cleared of mud, it is piles high on the roadway...

I wounder What was the design load? Did the design condition consider people sometimes stand packed as tight as possible, or stand to one side of a gangway? Was a load test performed at construction? Gangways are not buildings, there is essentially no dead weight. Buildings are typically at...

It is done with inverter type generators, which require a control cable connection. https://generatorinsights.com/how-many-inverter-generators-can-you-parallel/. Variable Speed Drives are not as far as I am aware built with that capability (at least as a standard product). There are a few...

More details matter, the Nolichucky funnel. https://tdeconline.tn.gov/nolichucky/ New flow estimate for the Nolichucky river during Halene reached an overwhelming 84,000 cubic feet per second (usgs river gauge was off scale, so this number is not calibrated and subject to change.)...

[ponder]This is a very good example of codes needing to be fit for purpose. It is also a good example of why mixing codes does not work. The electric requirements of 46CFR works with IEEE 45 Recommended Practice for Electric Installations on Shipboard, not the National Electric Code. I had...

You may want to look at solutions that do not submerge the electric parts. One such system is fiber optic lighting. Linked are some examples https://www.srsmith.com/en-us/products/pool-lighting/https://www.srsmith.com/en-us/products/pool-lighting/...

So afloat you must do something I would never consider ashore.

Elevation at Rutherford NC ~ 700 ft (Piedmont) Walnut creek at green river - 800 ft (downstream end of gorge) Adjacent Blue Ridge escarpment - ~2500 ft (typical) Adjacent mountain tops ~ 4000 ft. This is enough elevation change to wring water out of clouds. Elevations from USGS Topo builder...
