I'd use a different photo as the location of the detectable warning pavers is out of spec.

Great picture! How do I obtain permission to use it in an article I'm writing? Pbaker@ivyautomation.com

Shouldn't the sheet piled be seal-welded at the joints to create the idea of s water tight structure ???

Re: Olympus Dam, Estes Park, Colorado – Flood Control, Power Generation

As you will read in the article, there are questions being raised about the Dam's roll in the recent flooding down the Big Thompson canyon. The Bureau of Reclamation officer made the comments in response to those concerns. I happened upon your photo as part of a google search and thought I would mention it. I think the comment by the officer is largely true because the dam is part of the Colorado-Big Thompson water diversion project. But it's also possible that flood control was thrown in originally.

Thanks for the comment and correction davebf. We'll get that fixed right away! I read what I wrote down somewhere, but I can't find the resource as it was a few years ago. It seems the public affairs spokesperson for the Bureau of Reclamation's Great Plains office is a good source. I wonder where the source I was reading got their information?

You might want to check out this article:http://www.eptrail.com/este...

"Olympus Dam holds back the water in Lake Estes. Lake Estes is not a flood control reservoir, nor was it built for storage. Lake Estes is a regulatory reservoir. It was built to help regulate hydro-power generation."

É bom produz energia elétrica,mas causa açoriamento na cabeçeira do rio.

Here is a link to a photo of the replica Idylwilde Dam:

It has some selective compression to fit the actual layout space. Also, the area is not mountainous where is sits on the layout (pay no attention to the fact that there are also rails going along side the water...).

Mark A. Baczkowski worked with me to create it based upon several pictures of it we found on the internet and from satellite images. I think it came out pretty nicely.

Thanks! Sounds good. It will be some time, but I will definitely send the photo.

Laugh?! I run a civil engineering photo site, I think it's awesome! :) Maybe you can send a photo to us and we can put it on the site when you are done

Wow. Thanks very much for the info. Don't laugh, but I'm trying to model the region on a model railroad. I liked the look of this one over Olympus Dam (although that one makes more sense for the area I'm modeling). I think this will be slightly easier to model as well. I really appreciate it! I love the Estes Park area.

Todd,

Thanks for the comment. I took this photo when I was in Colorado two summer ago driving to Estes Park. I did a little research for you though and that dam is the Idylewidle Dam on the Big Thompson River.

What's your project about?

Hi, I came across this image looking for images of dams near Estes Park. I would like to find more images of this dam. Do you know the name or can I get information on the location of the dam? I'm having trouble locating it. Thanks very much.

Re: Dynamic Pile Testing

Nate — Fri, 06 Apr 2012 06:45:40 -0000

It is a much faster test to run. Dynamic testing takes as long as it does to drive a pile so maybe 30-60 minutes/pile. A static load test can take 4-8 hours to set-up and complete. On the other hand Static Load test is still the industry standard and thusly a dynamic pile test program has to test usually twice as many piles. Don't quote me on this but I believe the Factor of Safety for driven piles with 1% of all piles being static load tested is 2.0. While for a high-strain dynamic test on 2% of all piles is 2.25. You'll get to learn a lot more about this I'm sure because G2 does high-strain dynamic testing.

Does dynamic pile testing offer any benefits when compared to full scale static load tests? Any disadvantages?

Thanks for this picture ,Our master at Fasa University told us last week to find some photos from supports as a Homework.

Re: Railroad Embankment Failure

Karl Jansen — Fri, 17 Feb 2012 18:46:10 -0000

Most of the information I got here was from various articles on AnnArbor.com
There may have been a few small details I included that I got from some worker at the site who was making sure people weren't wondering too close because it would have been dangerous (there where some utility poles with live electricity that where barely in the ground - see utility pole in middle of photo).

That's cool that you're involved in a semester long project on this local disaster. Hope it turns out well for you.

Re: Railroad Embankment Failure

Jake Clay — Fri, 17 Feb 2012 13:25:09 -0000

Karl, this failure is the subject of a semester long project for me in the Civil Department at U of M. And I was wondering if you had sources for the information you present here.

Re: Collapsed Building Port-au-Prince, Haiti

Alex R Mead — Wed, 25 Jan 2012 01:33:27 -0000

It probably would not have failed is my guess. It was standing fine during normal loading but the large increase in energy delivered to the building during the earthquake is what took it down. Another large energy event also could have taken it down, such as very large wind loads, an explosion, or perhaps a runaway vehicle.

Re: Collapsed Building Port-au-Prince, Haiti

Jake Clay — Tue, 24 Jan 2012 16:47:08 -0000

If this building were not subjected to an earthquake load would it have failed, or is it because of the earthquakes loads that this building failed?

Re: Fire Hydrant Drinking Fountain

Alex R Mead — Wed, 21 Dec 2011 19:06:58 -0000

Claudius,

Yeah I think the reason it looks clumsy is two fold.

One, that cage near the hydrant is a covering a back flow preventer. This is a connection piece that ensures no water, and more importantly crap that water contians, flows back into the water distribution system. If pollutants got in there it would be a big issue.

Two, I believe the rack has an additional filter, perhaps to remove any final taste, just because it is for drinking purposes. The water is definitely safe to drink right out of the hydrant, but many people like additional filtering for taste reasons, or paranoia :).

Hope this helps.

Yes, it would be part of any structural analysis.
