1. FOR "PARTIAL DEPTH REMOVAL" AREAS SHOWN ON CP102, THE CONTRACTOR MAY LAP SPLICE NEW WITH EXISTING #9 BARS AS

AND REDUCE CONCRETE REMOVAL WIDTH TO A DIMENSION THAT WILL ALLOW SPLICE INSTALLATION, BUT NOT LESS THAN 6".

SEE SHEET S-502 FOR SECTION CUTS WITH REQUIREMENTS FOR THE MECHANICAL BUTT SPLICE OPTION, APPLICABLE ONLY FOR

"PARTIAL DEPTH REMOVAL" AREAS SHOWN ON CP102.

2. FOR "MORTAR REMOVAL" AREAS SHOWN ON CP102, INSTEAD OF REMOVING AND REPLACING CONCRETE AS SHOWN ON SHEET

S-501, THE CONTRACTOR MAY ELECT TO REMOVE AND REPLACE FULL DEPTH SLAB SECTIONS AS SHOWN ON S-503. MECHANICAL
