THIRD INTERIM REPORT Description of Deficiency Before issuance of General Construction Specification TVA G-32 R6, " Bolt Anchors Set in Hardened Concr-ete," (Pebtuary 17, 1981) which provides screening criteria to TVA's Division of Construction (CONST) inspectors for expansion anchor spacing, CONST had minimum anchor spacing criteria as provided by G-32 R5 which could have been inadequate under certain circum-stances. This means that CONST inspectors could have applied the minimum spacing criteria to specific attachments being inspected without noting adjacent attachments that could influence expansion anchor spacing requirements. As a result, it is possible that expansion anchors have been installed which do not meet minimum spacing requirements when combined action of multiple attachments are considered.
Interim Progress Implementation of an inspection and sampling program is proceeding.
Additional information will be forwarded in our next submittal.
