1. EXISTING ROOF: BUILT UP ROOF WITH BROADCAST AGGREGATE

ON TAPERED PERLITE WITH APPROXIMATELY 3" THICK AT EDGE

OF ROOF DRAINS AND 9-1/2" THICK AT ROOF PERIMETER. PERLITE

APPEARS TO BE SET IN PITCH DIRECTLY ON CAST IN PLACE

CONCRETE DECK.

2. CLEAN EXISTING CONCRETE DECK SUFFICIENTLY TO PROVIDE A

SURFACE SUITABLE FOR ADHESIVE ATTACHMENT OF THE NEW

RIGID INSULATION. PROVIDE ONE SQUARE SAMPLE AREA FOR

CONFIRMATION WITH ROOFING MEMBRANE MANUFACTURER.

3. DIMENSIONS, ROOF THICKNESSES, LOCATIONS, SIZES AND

ORIENTATIONS OF ALL ROOF AREAS AND ROOF MOUNTED ITEMS

ARE ALL APPROXIMATE. FIELD VERIFY ALL CONDITIONS

THROUGHOUT.

4. UNLESS NOTED OTHERWISE, DASHED LINES INDICATE WORK TO

BE DEMOLISHED AND REMOVED.

5. DRAWINGS ARE DIAGRAMMATIC AND DO NOT SHOW EVERY ITEM

TO BE DEMOLISHED; WHETHER LISTED OR NOT, REMOVE ALL

COMPONENTS NEEDED FOR NEW WORK.

6. PROTECT ALL WORK THAT IS SCHEDULED TO REMAIN FROM

DAMAGE.

7. PRIOR TO EXECUTING WORK, NOTIFY THE ARCHITECT IF

CONDITIONS DEVIATE FROM WHAT IS SHOWN.

8. DEMOLISH ALL LIGHTNING PROTECTION SYSTEM COMPONENTS

THROUGHOUT WITH THE EXCEPTION OF ALUMINUM THREADED

GROUND RODS ATTACHED TO ROOF DECK.

9. SALVAGE ALL STAINLESS STEEL FLASHING AND COPING FOR

DELIVERY TO METAL RECYCLING COMPANY. OWNER WILL

COLLECT VALUE OF RECYCLED MATERIAL.

10. CONFIRM IF CONDUIT OR PIPE PENETRATIONS ARE STILL IN

SERVICE. WHERE NO LONGER IN USE AND/OR CAPPED ABOVE

ROOF, REMOVE LINE TO BELOW ROOF DECK AND CAP. WHERE

STILL IN USE, REMOVE ALL PITCH POCKETS, MASTIC, LEAD

FLASHING AND PREPARE FOR LIQUID FLASHING.

11. CUT BACK TREE BRANCHES FROM EXTERIOR FACE OF ROOF

PARAPET 24" CLEAR MIN. THERE SHALL BE NO TREE BRANCHES

ABOVE THE ROOF OR PARAPET.

CONCRETE ROOF DECK. ENTIRE SYSTEM IS SET IN ADHESIVE ON EXISTING ROOF DECK IN

PATTERN ENGINEERED BY ROOF MEMBRANE MANUFACTURER TO RESIST UPLIFT. PROVIDE 3/16"

PER FOOT SLOPE TYPICAL UNLESS NOTED OTHERWISE. REFER TO DETAILS AND SPECIFICATIONS

FOR MORE INFORMATION.

2. LIGHTNING PROTECTION SYSTEM: PROVIDE LIGHTNING PROTECTION SYSTEM THROUGHOUT

AREAS WHERE ROOF IS REPLACED UNLESS NOTED OTHERWISE. RE-USE EXISTING ALUMINUM

THREADED GROUND RODS ATTACHED TO ROOF DECK WHERE POSSIBLE. SEE DETAIL -

3. METAL FLASHING: ALL METAL FLASHING, COUNTER FLASHING, EDGE METAL AND COPING NOTED IN THE DRAWINGS SHALL BE 24 G.A. STAINLESS STEEL TO MATCH THE EXISTING 9 STORY ROOF.

4. SEE SHEET A911 FOR ROOFING DETAILS. WHERE DETAILS ARE NOT SHOWN, PROVIDE STANDARD

DETAILS AS RECOMMENDED BY THE ROOFING MANUFACTURER AND NRCA. REPORT ANY

DISCREPANCIES BETWEEN DETAILS, MANUFACTURER’S RECOMMENDATIONS, AND FIELD

CONDITIONS TO THE ARCHITECT.
