I have not been able to filter this out of other threads so forgive me if this duplicates:
I have a site where we have some saturated sand and silt (non-plastic) materials with very low blow counts found in two out of ten borings to depths of about 65 feet. These two borings are in the same...
The testing for Radon that I have done has been based on completed structures. I have been given a specification that calls for Radon testing of import fill, prior to delivery at the site (looking for <400 picoscuries per Liter).
I have been looking for a specification that discusses testing...
I have just found out that the owner of our small firm let the our liability insurance laps. It is currently being reinstated, with no loss of coverage.
My question is how or could this have impacted me, as a PE working for the company and signing documents? If a claim had been made, would I...
Well, I wanted to see what others thought of this situation:
We are performing QC for a contractor/supplier for a concrete highway project overseen be the local DOT (USA). We performed a concrete mix design for our client. When they set up the plant, an error was made and the sand and coarse...
I have come across a new problem that I have not seen before. We are getting a thin film over the top of the water surface in our curing tanks. The film is sort of off-white/translucent, and is like a thin crust.
The one tank had been used for holding buckets for sodium sulfate durability...
Well, search did not turn up what I was looking for.
I have a site that has some all-welded steel pipes. The pipes run “generally” downhill at a slope of about 1.5H:1V. The run covers a drop on the order of 1500 feet (yes, a long way). The pipes are laid on the ground surface, and have been...
I have looked at a slope that has failed. That is, there has been movement in both wet and dry times. At the time I saw it, there was about 1 foot of vertical displacement at a gravel access road (bench)near the top of the slope.
We are looking at ways to stabilize the slope, but the client...
So, just a quick poll, How mny got raises this year, in this economic climate?
My company is not doing any raises for anyone, including me, of course? This goes for the people working for me.
Some are hapy to just have a job at this point, others want to see an increase that the profit...
In the US, are there any issues or restrictions (like from the IRS) for a salaried employee working 4 ten hour days? The company I am at says there are issues with that, and you must work on at least 5 days a week, but not necesarrily 8(+) hours a day. I don't want to do it all the time, just...
I am having quite a dilemma… I was approached by my previous employer to come back to the company, at a higher level, at a different office than I worked before (company is not that big, so I did get to know some of the people during my 8 years there). This opportunity was not present at the...
Not sure if this was mentioned here,but:
I recommend the message board at www.mrexcel.com for tough excel issues you may have.
There are some serious Gurus there that have saved me a lot of time and extra coding.
Can someone tell me if this spec also covers the orientation of the perforations when the pipe is used for drain purposes?
We have a situation where a foundation drain is being installed. The arch/structural/civil, whomever has specified ASTM D2729. The submitials show the perfs down, and the...
First: Yes, I searched and found 14 threads on the subject. No, they did not answer the question.
We have been conversing at the office about laterally loaded piles in sand. We normally provide a couple methods for the structural to use to calculate capacity (Lpile criteria and the one I am...
I am looking at several homes with sulfate attack on the grade beams, near the ground surface.
Background:
1. The homes are about 3 years old.
2. Water Soluble Sulfates range form 1.2 to 2.7%.
3. We specified Type V cement for the mix, although not sure what the structural specified or...
I have developed a sheet that allows me to summarize information off of a sheet in excel. The sheet is also printed as a table for insertion into a report, to show a table of lab testing results.
I have the formatting of the sheet to have a double line at the bottom of the page. This all...
This is not project specific, but a request for opinions.
I have been working with a structural engineer that has expressed his dislike of helical piles. His concern is this: He feels the auger going through the soil disturbs it, leaving the pile shaft "unsupported". He worries that the...
I am working on Geotech recommendations for a contiguous bored pile wall. The wall will be used to retain 10 feet (15 feet temp to install a drainage system). Up to 15 feet of fill will be placed above the wall to form the approach to a bridge.
The subsurface conditions include sands (~20...
