REPAIR OF CONCRETE VOIDS IN TENDON ACCESS GALLERY We have reviewed the applicant's repair program for the cencreta voids in the tendon access gallery as presented in Mr. N. C. Moseley's letter of February 5, 1969. Two items which we feel the repair should keep in mind are:

(1) Ihe epoxy used should have a durability equal to the structure's life span.

(2) The new grout / concrete should he adequately tied back to the main concrete.

As va foresee no difficulties in obtaining the desired results for (1) and (2) under the program proposed, we have no objections to the applicant proceeding with the repairs as presented.
