FIT NEW FLOOR GRATING AROUND JIB CRANE.
SUPPORT FROM WALL IN SAME MANNER AS EXISTING
PLATFORM.
NOTES:
1. OWNER WILL EMPTY THE MAJORITY OF LIQUID/SOLID CONTENTS.
CONTRACTOR SHALL POWER WASH INTERIOR WALLS AND FLOOR
AND TRANSFER ALL WATER TO THE HEAD OF THE PLANT UNLESS
COORDINATION WITH OWNER ALLOWS DRAINING TO SLUDGE
THICKENER.
2. CONCRETE PLATFORMS SHALL BE POWER WASHED BUT NEED NOT
BE COATED.
3. INTERIOR AND EXTERIOR VISIBLE CRACKS, ESPECIALLY THOSE
WITH EFFERVESCENCE, SHALL BE EPDXY-INJECTED PRIOR TO
COATING WALLS.
4. REPAIR ANY SPALLING AREAS OR VOIDS GREATER THAN 4" DEEP
WITH CEMENTITIOUS MORTAR.
5. ENGINEER SHALL BE CONTACTED TO OBSERVE ALL SURFACES
INTERIOR AND EXTERIOR PRIOR TO CONTRACTOR PROCEEDING
WITH COATINGS.
6. COAT EXTERIOR WALL OF BOTH TANKS, AND INTERIOR AND
EXTERIOR VALVES AND PIPING, AS PER THE SPECIFICATIONS.
7. APPURTENANCES INSIDE AND OUTSIDE TANKS TO BE REMOVED
AND PUT BACK AS NEEDED DURING COATINGS PROCESS WITHOUT
DAMAGE TO APPURTENANCES.
8. LIFTING CABLE TO THE DIGESTER MIXER ADJACENT TO THE ROOF,
WHICH IS BROKEN, SHALL BE REPLACED. USE STAINLESS STEEL
AIR CRAFT CABLE OF SAME SIZE AS EXISTING.
9. FOR THE DIGESTER ONLY, THE ENTIRE INSIDE SURFACE OF WALLS
SHALL BE COATED AS PER THE SPECIFICATIONS. THE DIGESTER
FLOOR SHALL BE COATED ALSO IF NEEDED (SEPARATE
ALTERNATE BID ITEM).
10. TEST EACH TANK FOR WATERTIGHTNESS UPON COMPLETION OF
EPDXY INJECTION AND, FOR DIGESTER ONLY, UPON COMPLETION
OF INTERIOR COATINGS. USE WATER FROM OWNER'S WATER
SYSTEM. AFTER A SATURATION PERIOD, MARK LEVEL ON TANK
WALL AND CHECK AT 24 HOURS LATER. THERE SHALL BE NO
VISIBLE LEAKS THROUGH WALLS AND ANY DROP IN WATER LEVEL
SHALL NOT EXCEED THE ALLOWABLE AMOUNT PER ACI 350.1,
SECTION 2, QUANTITATIVE CRITERIA.
11. THE TWO NEW PLATFORMS WITH RAILS, STAIRS, SUPPORTS,
HARDWARE, AND PAINT SHALL BE MORE FULLY DETAILED BY A
QUALIFIED METAL FABRICATOR. SHOP DRAWINGS TO BE
SUBMITTED AND APPROVED BY ENGINEER PRIOR TO FABRICATION.
PLATFORM NO.1 SHALL BE DESIGNED BY A NC PROFESSIONAL
