NOTES:

1. EXISTING STEEL BEAM SIZES SHOWN FOR REFERENCE. FIELD VERIFY SIZES AND INFORM STRUCTURAL ENGINEER IF SIZES DIFFER FROM SIZES SHOWN PRIOR TO COMMENCEMENT OF WORK. EXISTING BEAMS MAY NEED TO BE REINFORCED IF FIELD VERIFIED SIZES DIFFER FROM SIZES SHOWN. ALL EXISTING STRUCTURE LOCATIONS, ELEVATIONS AND CONDITIONS TO BE FIELD VERIFIED. 2. CONTRACTOR IS RESPONSIBLE FOR SHORING ALL EXISTING AND NEW STRUCTURES PRIOR TO ANY REMOVAL AND MODIFICATION OF EXISTING MEMBERS. 3. ALL EXISTING CONDITIONS AND DIMENSIONS MUST BE FIELD CONFIRMED PRIOR TO COMMENCEMENT OF WORK. 4. DO NOT OVERLOAD ANY AREAS OF EXISTING SLAB WITH REMOVED MATERIAL. 5. FOR TEMPORARY LATERAL BRACING OF THE EXISTING STRUCTURE, THE TEMPORARY BRACING MEMBER SHALL RESIST 2% OF THE TOTAL VERTICAL LOAD IMPOSED INTO MEMBER. THIS LOAD SHALL BE APPLIED IN ANY DIRECTION AND SHALL BE SPECIFICALLY DISTRIBUTED IN PROPORTION TO THE MASS. 6. IN THE PROCESS OF DEMOLITION, THE CONTRACTOR SHALL NOTIFY THE ENGINEER/OWNER WHEN ENCOUNTERED/DISCOVERED ANY STRUCTURAL ELEMENTS THAT APPEAR NOT TO BE SOUND, CORRODED AND/OR

• DELAMINATED. THE CONTRACTOR SHALL STABILIZE THE STRUCTURE.

7. COORDINATE CONSTRUCTION PHASING WITH OWNER, MAINTAINING ACCESS AND OPERATIONAL RESPONSE TIME TO THE FACILITY TO FULLEST DEGREE POSSIBLE. 8. SIDEWALK AND DRIVEWAY REPLACEMENTS SHALL BE IN ACCORDANCE WITH DOT RULES AND REGULATIONS. 9. CAREFULLY REMOVE AND RESET SIDEWALK TO OBTAIN PROPER DRAINAGE

• GRADES. RESET FILL LINE FOR ANY UTILITIES ENCOUNTERED IN WORK AREA.

10. CONTRACTOR SHALL FILE ALL NECESSARY APPLICATIONS AND OBTAIN ALL PERMITS AND APPROVALS WITH MUNICIPAL AUTHORITIES HAVING

• JURISDICTION. CONTRACTOR SHALL SECTION-OFF THE WORK AREA FROM

PEDESTRIAN ACCESS AND PROVIDE A SAFE WALKWAY AROUND THE CONSTRUCTION AREA. 11. THE NEW SIDEWALK CONCRETE-ON-SLAB GRADE SHALL BE NORMAL WEIGHT CONCRETE WITH 4000 PSI 28 DAYS COMPRESSIVE STRENGTH REINFORCE WITH 6X6-W2.9XW2.9 WELDED WIRE FABRIC.
