Thanks to Jeanine Szalinski's hard work and to Bill Matthew's financial support for the Right To Know, I picked up the geotechnical report from the school district this morning. Here it is. Geotechnical report According to page 83 of 88 pages, CEC sent a letter (addendum) to Mrs. Kathy Stoughton of Celli Flynn Brennan claiming that a tested sample indicated a pyrite content of 0.27%. The letter states that "Materials containing as little as 0.1% pyrite have been documented to produce heaving in lightly loaded structures such as floor slabs or utilities if conditions are right."
Don't tell the wood flooring folks about this or else they will not stand behind their warranty. But let's just keeping on moving forward, folks.
Update September 17, 2012 1:15 PM Generalized Soil Profile as promised.
CEC, the engineer, sent a letter to Celli-Flynn that recommended remediation of pyrite on the site and gave examples on how to remediate.
ReplyDeleteCelli-Flynn then later recommended to the Board that it would be ok to NOT do pyrite remediation? And the board voted to cut it out of the bids for the project.
Or did Celli-Flynn recommend to remediate but was overruled by someone like the board or PJ Dick?
Either way, Celli-Flynn, based on this report, should have been adamant about doing pyrite remediation as part of the bids.
Give me a couple of minutes and I will add the Generalized Soil Profile. It was printed on two sheets of 11"x17" paper, so I had to cut them in half to scan. They will uploaded momentarily as an update.

CEC stands for Construction Engineering Consultants, Inc., not to be confused with Community Advisory Committee (CAC) with members such as Dirk Taylor, Dave Disque, and Dan Rothschild, just to name a few.

Unless you are a qualified soils or geotech engineer you will probably not really be able to understand the test data, charts or graphs. I don't. A site map on page 7 shows where all the test borings were located. There is a suspect test boring area (B-12) just to the south of building F. The "New Fieldhouse Addition" narrative is covered on pages 14-16. Tech types are directed to the balance of the doicument to distinguish between the multitude of silty soil designations and comprehend the data.
ReplyDeleteIt seems most of the site, and particularly the site area of the athletic building HJK consists of fill from years ago, sometimes nearly 35' deep, some absolute crap. Then there is the reality that abandoned coal mines are some 200' under the entire area, and consideration of mine subsidence insurance was suggested.
