I need some technical publication articles, papers, etc. citing problems with jetting new fill in attached garages. I have exhausted many attempts to find such articles in ASCE and other sources. Purpose is to show my neighbor builder it is very dangerous. He has built many a house and...
Came across a metallurgy example at my house that is interesting. We have a flower garden in town where there are many deer. They love to eat peoples flowers for some reason. So I surround the flower area with a fence of steel bailing wire on fiber glass rods at about 30" height. A timed...
I';m a civil engineer but also a Ham operator, but know nothing about using GPS (our surveyors use it I think). In the past three months the Police here stop in because they are getting a false alarm at our address (three times now). Our single cell phone is not turned on, but uses a local...
I have struggled with the code committee for foundation drain requirements in Wisconsin. Code committee consists of plumbers. no engineers. Result: Not much cooperation. I am looking for language from municipal or state agencies which properly addresses requirements to prevent plugging of...
In the Nov 25 - Dec 5 issue of Engineering News Record, editorial by Thomas Schleifer, PHD he notes that many construction project failures by contractors, as well as others, is due to them taking on jobs which are not types they have experience in. He is offering a free program for...
Not an engineering failure but of interest to engineers.
Something fishy here when trench box is needed after the fatality.

There is another post on the subject of "lateral earth pressure" on a deep shaft. Perhaps mining engineers can contribute to that subject. Look for "Lateral Earth Pressures on a Deep Rigid Shaft ". It is post thread255-415476
I've been reviewing some reports in the last few years with SPT values on the logs given as "corrected". With many older tables out there based on past experience, I question anyone making any changes to the SPT values coming out from this crude test in the field. I view them as wishful...
Noted on Fox News several buildings collapse due to sliding stored earth piles nearby.

Check out this ENR article.

The explanation of the problems cause sounds fishy.
What the heck is "compressed gravel" or "watertight soils".
Also what is an "artesian...
I figure you all might want to examine the photo on Geotech Other site. I managed to freeze the TV shot. Seems like the driller's aim was good between the two rails.
Most of us call the One Call to be sure that you don't mess up underground utilities. However, I suspect they don't have good information on the location of NYC Underground Subways. This picture showed up while I was watching Fox news this morning. Sure looks like a hollow stem auger that...
A friend of mine in Sweden tells me that studded tires in cities are reported to bring up to the atmosphere asphalt dust of some type that is causing illnesses and deaths. Can someone explain the situation in engineering terms so that engineers elsewhere might benefit from the information...
I've been asked for a reference or formula for correcting unconfined compression tests on samples shorter than twice the diameter. I used to have that in my files, but now no luck. I understand there is such a correction for short concrete cylinders, but I can't even find that now. Help.
Here is a link to a local news paper article. On TV I heard "engineers say no problem since building is founded on rock". Ya?? Looks like it might be a problem shifting things to the river.

This link shows some tilted columns and comments about a dirt pile nearby maybe the cause?

News papers and TV are not giving much that we,as engineers,could use or which may better explain things. Information on past slides and the current one would be of interest to all if it deals with technical causes, etc. Perhaps engineers in the area can comment here.
Engineering-News-Record has a short article in the March 10th issue indicating a summary of the fix. Here is a photo copy of that article. I could not find a link on their WEB site for this article, as usually is possible.
For some interesting photos and general design scoop this is a job nearing completion.

Other info is available on line also.
A 10" plastic gravity sewer was installed about 40 years ago and it then was 4 feet below stream bed at the crossing. Recent flooding conditions have exposed it so there is perhaps 3 feet of water depth beneath it and it is barely under the water surface now. One fix planned is construct a...
