1. THE CONTRACTOR SHALL CONDUCT ALL FIELD MEASUREMENTS NECESSARY TO FABRICATE THE NEW STAIR TO FIT WITHIN THE EXISTING LIMITS AND MEETING THE HISTORICAL RESTORATION OF THE PROJECT TO THE EXTENT DEMONSTRATED IN THESE DOCUMENTS. 2. THE CONTRACTOR SHALL BE RESPONSIBLE FOR ALL MEANS AND METHODS FOR EXTRACTING THE EXISTING STAIR AND RAILING FROM THE SITE. THE CONTRACTOR SHALL INCORPORATE INTO THEIR METHODS INCORPORATION OF TEMPORARY PROTECTION MEASURES TO PROTECT ALL STRUCTURES AND PAVEMENTS AND MAY INCLUDE 'HARD ARMORING' IN THE FORM OF PLYWOOD OR SIMILAR TO PROTECT SURFACES (GLASS, WOOD, AND STONE BUILDING FASCADE, BRICK RETAINING WALL, SANDSTONE WALL CAP/WALK THRESHOLD, AND PUBLIC SIDEWALK) AS NECESSARY. 3. THE SIDEWALK AND STREET ARE PART OF THE CITY OF CANTON PUBLIC WAY. THE CONTRACTOR SHALL PROTECT THE PUBLIC AT ALL TIMES WITHIN THE PUBLIC WAY, SHALL LIMIT TEMPORARY STAGING DURATIONS TO A MINIMUM TIMEFRAME, AND BE RESPONSIBLE FOR PROVIDING NOTICE AND OBTAINING APPROVALS FROM THE CITY TO TEMPORARILY RESTRICT USE OF THE WALK OR WEST DRIVE LANE IN ORDER TO REMOVE AND HAUL OFF EXTRACTED STAIR. THE CONTRACTOR SHALL PROVIDE ALL SIGNAGE, CONES, BARRICADES, OR OTHER METHOD OF REDIRECTING PUBLIC CIRCULATION TO THE EXTENT REQUIRED BY THE CITY. 4. ACCESS TO THE PUBLIC WALK FROM THE LOWER ENTRY OF THE NPS FACILITY SHALL BE PROVIDED FOR THE PERIOD OF TIME WHERE THE STEEL STAIRWAY IS OUT. THE CONTRACTOR SHALL CONSTRUCT TEMPORARY PROVISIONS OF 2X DIMENSIONAL LUMBER OR BETTER IN ORDER TO MAINTAIN THE REQUIRED EGRESS ROUTE FROM LOWER BUILDING LEVEL TO STREET. THE TEMPORARY STAIR CONDITION SHALL BE IN PLACE WITHIN 24 HRS AFTER THE REMOVAL OF THE EXISTING UNLESS APPROVED BY COR IN WRITING. 5. THE CONTRACTOR SHALL BE RESPONSIBLE FOR ALL MATERIALS AND PROTECTION OF THE PUBLIC FROM THE OPEN FALL PRESENT BY THE VOID OF A REMOVED STAIR. PROTECTION SHALL BE SECURED TO THE RAILING BY MEANS NON-DESTRUCTIVE TO THE RAILING OR WALKWAY. FREESTANDING BARRICADE EASILY MOVABLE BY THE PUBLIC IS INSUFFICIENT PROTECTION AND NOT ALLOWED.

REMOVAL NOTES:

AutoCAD SHX Text

1. ALL PUBLIC SAFETY AND PERMISSIBLE USE OF THE PUBLIC WAY NOTED IN THE REMOVAL NOTES ABOVE APPLY TO NEW INSTALLATION AND RESTORATION ACTIVITIES. 2. THE CONTRACTOR SHALL VERIFY THE SUBSTRUCTURE BEHIND THE BRICK TO CONFIRM ANCHORING OF NEW STAIR. THE CONTRACTOR SHALL BE PERMITTED TO SELECTIVELY EXTRACT MORTAR AND PULL UP TO 2 S.F. OF BRICK WALL SURFACE AREA UNDER STEPS AND RE-SET BRICK AND APPLY NEW MORTAR TO MATCH WALL. 3. HONED / FLAMED GRANITE TREAD- THE CONTRACTOR SHALL PROVIDE HONED / FLAMED GRANITE TREAD- THE CONTRACTOR SHALL PROVIDE - THE CONTRACTOR SHALL PROVIDE A SOURCE OF THE GRANITE MATERIAL. MATERIAL IS TO MEET TWO PRIMARY OBJECTIVES - 1) MATCH THE COLOR TONE AND MONOCHROMATIC APPEARANCE OF THE REMOVED SLATE STEPS, AND 2) PROVIDE A TEXTURED FINISH (HONED / FLAMED) TO THE STONE FOR A SLIP RESISTANCE FINISH. GRANITE SHALL HAVE A MOHS SCALE OF HARDNESS OF 6 MINIMUM. SUBMIT SOURCE OF MATERIAL AND (3) PHYSICAL SAMPLES OF DIFFERENT GRANITE OPTIONS (MIN 4"X4" X FULL 1 1/4" DEPTH) TO THE COR FOR SELECTION AND APPROVAL. THE COR RESERVES THE RIGHT TO REJECT THE SUBMITTED SAMPLES AND REQUEST OTHER GRANITE OPTIONS IF NONE OF THE SUBMITTED SAMPLES MEET THE CRITERIA OF COLOR MATCH AND SLIP RESISTANCE. THE COR ALSO RESERVES THE RIGHT TO REQUIRE PHOTOGRAPHIC EVIDENCE THAT THE APPROVED SAMPLE HAS SUFFICIENT SUPPLY IN ORDER TO COMPLETE THE FULL EXTENT OF TREADS. 4. ALL STEEL WORK SHALL BE IN ACCORDANCE WITH SPECIFICATIONS SECTIONS PROVIDED WITHIN THE STATEMENT OF WORK (SOW). 5. STREET LEVEL RAILING - THE ORNATE RAILING AND NEWEL POSTS STREET LEVEL RAILING - THE ORNATE RAILING AND NEWEL POSTS - THE ORNATE RAILING AND NEWEL POSTS INSTALLED AT THE STREET LEVEL WITHIN THE SANDSTONE BAND SHALL BE RESTORED IN PLACE. THE RAILING SHALL BE CLEANED BY CONTRACTOR SUBMITTED PROPOSED METHOD (WATER POWER WASH, LIGHT SANDBLAST, OR OTHER) TO THE COR FOR APPROVAL. RAILING AND NEWEL POSTS SHALL BE CLEANED TO THE EXTENT WHICH ALLOWS FOR A UNIFORM BOND OF PRIMER AND PAINT MATERIALS TO COMPLETE THE RESTORATION AND INCLUDES ANY FLAKING PAINT, TREATING SPOT RUST LOCATIONS, AND REMOVAL OF ALL GREASE OR OILY FILMS FROM POLLUTION AND HANDLING OVER TIME. PROPOSED METHODS SHALL INCLUDE METHODS FOR PROVIDING MATERIALS FOR PROTECTION OF THE SANDSTONE, BUILDING FACE, AND PUBLIC SIDEWALK. RAILING AND NEWEL POSTS SHALL BE FIELD PRIMED AND PAINTED. 6. SOUTHEAST STREET LEVEL NEWEL POST AND RAIL - THE NEWEL POST SOUTHEAST STREET LEVEL NEWEL POST AND RAIL - THE NEWEL POST - THE NEWEL POST IS OUT OF PLUMB AND THE TOP PIPE RAIL HAS SEPARATED FROM THE NEWEL POST FLANGE. THE CONTRACTOR SHALL SUBMIT A PROPOSED METHOD OF FIELD REPAIRING, WHICH MAY INCLUDE PROVING A NEW FLANGE TO RECONNECT THE PIPE, SHIM AND RESET NEWEL POST TO PLUMB, OR OTHER AS SUBMITTED TO THE COR AND APPROVED IN WRITING. CLEANING, PRIMING AND PAINTING AS NOTED ABOVE SHALL THEN APPLY TO THE REPAIRED NEWEL POST AND RAIL. SEE SHEET L01 FOR SEE SHEET L01 FOR PHOTO IMAGE OF NEWEL P0ST CONDITION. 7. ELECTRICAL SCOPE OF WORK - A LICENSED ELECTRICIAN SHALL VERIFY ELECTRICAL SCOPE OF WORK - A LICENSED ELECTRICIAN SHALL VERIFY - A LICENSED ELECTRICIAN SHALL VERIFY THE ELECTRICAL SERVICE FROM THE CIRCUIT BREAKER AND PROVIDE NEW EXPOSED CONDUIT AND WIRING TO A NEW WATER TIGHT NEMA BOX AND CAP SERVICE AT THE BOX FOR FUTURE PARK USE. CONDUIT AND BOX SHALL NOT EXCEED THE SIZE OF CURRENT HOUSINGS AND SUITABLE FOR EXTERIOR EXPOSURE. THE CONTRACTOR SHALL PROVIDE AN ENCLOSED EXTERIOR SHUT OFF OF THE POWER SIMILAR TO EXISTING PROVISION AND UPGRADED TO MEET CURRENT ELECTRICAL CODES AND STANDARDS.
