The demand is there as well as the potential clients (networked with most of clientele). Starting out as a QC/QA testing lab seems the most feasible at first. Exploration drilling to follow as it requires a much larger upfront purchase. Been eyeing either a Boart or Simco rig. Trying to phase...

Thanks, appreciate the suggestions. I intend, as you suggested, buying the essential (most common tests) then proceed with the more complicated/less common tests as projects require them. I was fortunate in the past to utilize fully-automated lab equipment (i.e. triax, trial-based perm tests...

The lab I'll be setting up will be a new business venture (materials lab) so I'd like to hear anyone's thoughts on equipment as far as value. I don't mind spending more for particular equipment, granted, they perform/last with consistent/accurate results (assuming properly calibrated and...

Hi All, I'm in the early stages of setting up a materials testing lab and would you like to hear what you recommend for purchasing new lab equipment. I'll be starting out simple (i.e. concrete - cylinder compressive tests, fresh field concrete sampling and testing, flex bend test, soil - PI...

Thanks for the feedback. Attached is a pdf of my Slope/W slope stability analysis of what I believe the site conditions were at. Let me know what you think.http://files.engineering.com/getfile.aspx?folder=b08d7f41-0a86-4295-9682-2849c6337406&file=Slope_with_soil_bldg_and_unsupported_slope.pdf

Based on what you all mentioned and the results in Slope/W, seems like one scenario of how the collapse happened is that with the heavy rains, the soil became increasingly weaker. The garage excavation created a very unstable slope, greatly reducing the confining pressures close to the building...

Any ideas to the loads and moments experienced in the building collapse? It looks to me that it wouldn't take much to snap those hollow piles with such soft soil around the foundation and the garage excavation.

Thanks for the good info. I'll take those things into consideration and see what I come up with.

Thanks for the input. I believe the "shear force" required by Slope/W is the force induced by the piles unto the surrounding soil, as some kind of reinforcement. It seems to me that one of the key factors in the failing is the fact that the face of the excavation was left unsupported. They did...

I see, its just that in Slope/W they require you input the shear force of the pile and I'm not too sure what value to put there. An example analysis uses a shear force of 300kN, but I'm not sure how they calculated that or for what kind of pile. Any thoughts? Thanks.

Hi all, I'm trying to model the Lotus Riverside Apartment building collapse in Shanghai, China using Slope/W. It appears that the building used 2' circle open-ended lightly reinforced concrete piles. Is there any quick way to calculate the shear force of these piles so I can best represent them...

Yep, trying to get help where ever I can find it. Been trying to find materials on it but not too successful and plus there having problems with the licensing for rockworks at my work so more head ache there. They did'nt realize that if you buy RockWorks single user it means, actual single user...

Im an intern working with tons of geotechnical studies and I am suppose to be making a digital database of these boring logs unto RockWorks 2006. No one here knows how to use the software, so it is basically a trial and error game right now. I have not taken soil mechanics so everything is new...
