NOTES:

1. INDICATES LOCATION OF RESISTANCE PIERS WITH RETROFIT FOUNDATION BRACKET. EACH PIER SHALL PROVIDE 8k ALLOWABLE BEARING CAPACITY (12k ULTIMATE w/FACTOR OF SAFETY OF 1.5 FOR TEMPORARY SUPPORT). 2. INDICATES LOCATIONS OF SOIL TIE-BACK NAILS. EACH TIE-BACK SHALL PROVIDE MINIMUM ALLOWABLE PULLOUT CAPACITIES PER SKETCH 1/SK-2. LOCATIONS ARE ALSO DESIGNATED ON 1/SK-2. 3. INDICATES EXTENT OF SHOTCRETE WALL. SEE 1/SK-2 FOR A WALL ELEVATION & VERTICAL DIMENSIONS. 4. THIS SHORING PLAN ASSUMES THAT THERE EXISTS A CONCRETE STEM WALL AS SHOWN ON PLAN 2/S-2 & SECTION 4/S-5 OF THE ORIGINAL STRUCTURAL PLANS FROM PFAU ENGINEERING DATED 6/15/88. SHORING PLAN MAY HAVE TO BE ADJUSTED IF ALTERNATE CONDITIONS ARE DISCOVERED DURING EXCAVATION.
