We’re evaluating the effects of heavy construction equipment operating near the edge of earth slopes. We are attempting to model the vehicle loads and want to consider them as distributed loads per tire over the tire’s contact area. Can we calculate contact area as load divided by tire...
I received a copy of a subsurface exploration report prepared a licensed engineer with geotechnical experience. The project is a 8000-square-foot, wood-frame commercial building, and the work was conducted for a local developer.
The report states that the field sampling was done using a...
A customer is proposing to store mineral oil (dielectric fluid for transformers) in an above ground, 3000-gallon capacity, polyethylene tank with a secondary containment stucture built around it. I have no specs on the tank and he might not have them, either. Two questions:
1) Is this a good...
Anybody know where I can rent/borrow the DCP referenced in
D6951-03 "Standard Test Method for Use of the Dynamic Cone Penetrometer in Shallow Pavement Applications". Thanks

Is it standard practice in your area (where are you?) to conduct periodic "backup" tests using sand cone (ASTM D1556), drive cylinder (ASTM D2937), or other methods to check the accuracy of tests conducted using a nuclear density device (ASTM D2922)?
Do you know of any authoritative published...
I am working with a local utility company evaluating the effects of construction loads on buried ductile iron and plastic water distribution pipe. We are considering construction vehicle and vibration loads on 6-inch and 12-inch buried pipe.
I am having difficulty finding literature that...
