2.8 Inadequate

Support of Tendons D eýmýnaýduring Pouring May identify additional perspective on this issue as RCA related efforts proceeds

Description:

If the tendons are not supported well, they may move during concrete pouring resulting in either or both, (1) localized friction between the tendon and its sleeve and (2) non-uniform stress in the concrete over the length of the tendon.Data to be Collected and Analyzed: Examine supports of hoop sleeves during construction.

(1) Examine supports of vertical sleeves during construction.

(2) Examine sleeve location and condition during demolition.

See Exhibit 1 as an example of a few pictures that show spacing during construction and SGR hole cutting.Verified Refuting Evidence:

Verified Supporting Evidence: 1. Photos from original construction demonstrate the support system.2. Photos taken during demolition show that the sleeves were evenly distributed in the zone and not deformed.Reviewed by: Dr. Avi Mor, 352-795-6486, ext 1030 -PII CR3 Team Office 11/23/2009 1*ot relca~c to ~ th.rd party vvithuut P~B~D2~1 L J t ,.
