'o ATTACHMENT I ADDITIONAL INFORMATION FOR I&E REPORT NO. 50-458/80-06 DEVIATION "A" As stated in GSU's initial response to Deviation "A" of Inspection Report 80-06, S&W Site Engineering has directed, in an' interoffice memorandum dated July 18, 1980, that efforts be made to place all concrete closer to the mix design air content-range to improve workability and place-ability. To confirm that the above direction has been adhered to, a random sample of concrete placements made during the period of May 15, 1980, through July 11, 1980, was selected and air contents averaged approximately 4.0%.

A similar random sample of concrete placements made during the period of August 30, 1980, through September 22, 1980, provided an average air content of approximately 5.0%.

It is our intent to continue to place concrete as close to the mix design air content as practicable in order to provide optimum placeability.
