1 November 2005 53:030 Soil Mechanics Experts 3505 Seamans Center for Engineering Arts Sciences University of Iowa Iowa City, Iowa 52242-1527 Dear Soil Mechanics Experts: We are a relatively new and small engineering firm in the Cedar Rapids area and we have just received a contract to do some preliminary site assessments for an advanced technology business park to be located off of Collins Road in Cedar Rapids. Your geotechnical-testing firm was highly recommended to us by one of your prior clients REAC who mentioned that you have done some excellent work for them this fall. To facilitate our site assessment, we are requesting that you take a core sample from the site at an appropriate depth and that you perform a one-dimensional consolidation test on it. In terms of results from this test, we are especially interested in the fine-grained soil's: 1. e vs. log[ σ v ’] behavior in 1-D consolidation, including estimates of C s , C c , and ( σ v ’) c ; 2. permeability k as a function of void ratio e, and 3. consolidation index c v as a function of void ratio e. For the sandy soil (FI-6) to be brought in to the site and compacted to a dry density of 17 kN/m 3 we are interested in its compressibility behavior. (Please note that a loose 1 kg specimen of this sand accompanies this letter.)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
