REPAIR / REPLACEMENT SCHEDULE NOTES:

RR-1: ALL QUANTITIES SHOWN IN THE ABOVE TABLE ARE ESTIMATES. ACTUAL QUANTITIES

WILL VARY DEPENDING ON LEVEL OF CORROSION ENCOUNTERED DURING DETAILED

INSPECTION BY THE CONTRACTOR. ACTUAL REPAIR & REPLACE QUANTITIES USED WILL VARY.

WHEREVER POSSIBLE, ALL REPAIRS SHALL BE CARRIED OUT AT GROUND LEVEL TO MAKE

INSPECTION MORE PRACTICAL AND PROVIDE BETTER AND MORE CONTROLLABLE WELDING

CONDITIONS.

RR-2: ALL PARTIAL AND FULL GUSSET PLATE 'REPLACE' WELDS SHALL BE DOUBLE SIDED

BEVELED FULL PENETRATION WELDS 'AS REQUIRED' (AR) AND THESE QUANTITIES ARE NOT

INCLUDED IN THE SCHEDULE ABOVE. ALL WELDS SHALL MEET ALL APPLICABLE AISC & AWS

D1.1 REQUIREMENTS FOR PRE-QUALIFIED WELDS INCLUDING DIMENSIONAL TOLERANCES FOR

GAPS ETC. PROVIDE BACKUP BARS IF AND AS REQUIRED AND REMOVAL FOR ALL EXPOSED

BARS.

RR-3: REPAIR PROCEDURE OUTLINE;

A) CHECK MAXIMUM CORROSION PITTING AND COMPARE TO 'WELD REPAIR THRESHOLD

SCHEDULE' [SECTION (4/S503)] TO SEE IF AND WHERE WELDING MATERIAL BUILD UP REPAIRS

ARE REQUIRED.

B) PREPARE ALL SURFACES AS REQUIRED (BRUSHING, GRINDING, SANDBLASTING ETC) FOR

WELDING AS REQUIRED PER AISC AND AWS D1.1 REQUIREMENTS TO ENSURE THAT

CORROSION DOES NOT REOCCUR IN THE FUTURE UNDER WELD REPAIRED AREAS.

C) FILL AREAS TO BE REPAIRED WITH WELD USING E60xx ELECTRODES AS REQUIRED. CLEAN

AND PREP BETWEEN ADDITIONAL PASSES AS REQUIRED.

D) GRIND ALL REPAIRED WELDED SURFACES, FAYING AND BEARING SURFACES, ADJACENT

AREAS AND TRANSITIONS AT PLATE REPLACEMENT. REMOVE ALL BURRS, WELD SPLATTER ETC

AS REQUIRED TO PROVIDE A SMOOTH FINISHED SURFACE PRIOR TO BLASTING & PAINTING

PREP SPECIFICATIONS.

E) SANDBLAST FINISH SURFACES TO BE PAINTED (INCLUDING FAYING SURFACES) TO SSPC10

('NEAR WHITE') AS A MINIMUM AND AS REQUIRED BY THE PAINT SPECIFICATIONS. PENCIL

BLAST ALL BOLT HOLES, INCLUDING HOLES TO BE ABANDONED, AND SIMILAR SMALL OPENING

AREAS TO SSPC SP10.

RR-4: ALL 'REPAIRS' TO CONNECTION PLATES, MEMBERS ETC SHALL BE BUILT UP TO THE

ORIGINAL MATERIAL FLUSH THICKNESS USING MULTIPLE FILLET WELDS PASSES AND GROUND

SMOOTH AS REQUIRED ON ALL FAYING AND BEARING SURFACES. CLEAN INTERMEDIATE WELD

SURFACES AS REQUIRED BY AISC AND AWS. THE MAJORITY OF CORRODED AREAS TO BE

REPAIRED CAN BE FILLED WITH A SINGLE PASS DEPTH (~3/16 " THICK/DEEP) FILLET WELD.

MULTIPLE PASS WELDS WILL BE REQUIRED TO BUILD UP AREAS WITH LOCALLY DEEP

CORROSION AND ARE ALREADY INCLUDED AS AN AVERAGE. GRIND AND PREP ALL WELD

SURFACES FOR PRIOR TO PAINTING TO SSPC SP 10.

RR-5: ALL REPAIRED AND NEW REPLACEMENT SURFACES TO BE PRE-BLASTED BEFORE

INSPECTION AND BLASTED & AND PAINTED TO MATCH ADJACENT SURFACES WITH INORGANIC

ZINC. SEE PAINT SPECIFICATIONS.

RR-6: E60xx ELECTRODES SHALL BE USED FOR ALL 'REPAIR' & 'REPLACEMENT' WELDS FOR

CONNECTIONS AND MEMBERS ETC.

RR-7: ALL GUSSET PLATE DIMENSIONS AND THICKNESS GIVEN ARE APPROXIMATE.

CONTRACTOR SHALL FIELD VERIFY EXACT SIZES. MATCH EXISTING GUSSET PLATE THICKNESS

AND FINISH DIMENSIONS.

RR-8: PROVIDE ALL OTHER MATERIAL PREPARATION STEPS AS REQUIRED TO PROVIDE A

COMPLETE STRUCTURAL SYSTEM THAT MEETS ALL APPLICABLE CODES AND STANDARDS

(AISC, AWS, SSPC ETC.) AND SPECIFICATIONS.

RR-9: IN GENERAL, THE EXISTING CIRCULAR BRACING/BRIDGING RODS ARE IN RELATIVELY

GOOD CONDITION ALTHOUGH THERE MAY BE HIDDEN OR UN-NOTED SEVERE CORROSION

LOCALLY THAT WILL NEED TO BE REPAIRED LOCALLY BY GRINDING AND WELDING BEFORE

REUSE. IF THE CORROSION IS SEVERE ENOUGH ALONG THE FULL LENGTH OF THE ROD,

OVERALL REMOVAL AND REPLACEMENT MAY BE WARRANTED IF THE REPAIR COSTS ARE 50%

OR MORE OF THE FULL ROD REPLACEMENT COST, INCLUDING ALL REQUIRED CONNECTIONS

AND FASTENERS. NOTE THAT THE END CONNECTION HARDWARE (CLEVISES AND ESPECIALLY

TURNBUCKLES) MAY NOT BE SIGNIFICANTLY CORRODED AND MAY BE SALVAGED AND REUSED

ALONG WITH ENOUGH OF THE THREADED PORTION OF THE RODS TO ALLOW FULL

PENETRATION WELDING. SIGNIFICANT ROD CORROSION RIGHT AT THE INTERFACE OF THE

CAST IRON TURNBUCKLES MAY REQUIRE THAT WELDING REPAIRS AT THESE LOCATIONS NOT

BE ALLOWED, AND PARTIAL ROD REPLACEMENT INCLUDING THE ADJACENT TURNBUCKLE MAY

BE REQUIRED.

RR-10: CAST METAL FITTINGS SUCH AS TURNBUCKLES ETC SHALL NOT BE REPAIRED BY

WELDING WITHOUT SPECIFIC APPROVAL FROM THE E.O.R. AND CONTRACTING OFFICER.

ALTHOUGH LOCALIZED CORROSION AND PITTING MAY EXIST, IT MAY BUT MAY BE EITHER

RELATIVELY INSIGNIFICANT, OR MAY BE LOCATED WHERE IT IS NOT CRITICAL TO THE

COMPONENTS STRENGTH. CONTACT THE CONTRACTING OFFICER FOR FURTHER GUIDANCE IF

SIGNIFICANT CORROSION IS FOUND.

RR-11: TIE ROD AND TURNBUCKLE THREADING MUST MATCH EXACTLY. WHEN TURNBUCKLE

REPLACEMENT IS REQUIRED, A PORTION OF THE CONNECTING RODS AT EITHER END SHALL

ALSO BE REPLACED, INCLUDING THE CLEVIS. THE REPLACED ROD END SHALL BE FULL

PENETRATION WELDED TO THE REMAINING INTACT ORIGINAL PORTION OF THE ROD.

RR-12: ROD COUPLERS FOR CIRCULAR HORIZONTAL RADIAL RODS SHALL BE 'CADWELD' OR

PRE-APPROVED EQUAL. INSTALL IN FULL COMPLIANCE WITH MANUFACTURER'S WRITTEN

RECOMMENDATIONS. ALL ROD ENDS AT EACH END OF SPLICES SHALL BE CORROSION FREE.

ALTERNATELY, 'COUPLING RODS MAY BE USED IN LIEU OF FULL PENETRATION WELDING FOR

SPLICING HORIZONTAL RADIAL RODS ONLY, AT NO ADD'L COST TO THE GOVERNMENT.

RR-13: REPAIR METHODS SHALL NOT BE CONSIDERED OR USED THAT WOULD RESULT IN ANY

FORMS OR TYPES OF UN-MAINTAINABLE SURFACES, OTHER THAN AT FAYING CONTACT

SURFACES.

RR-14: ALL REINFORCEMENT PLATES, SPLICES OR SIMILAR REPAIRS SHALL HAVE FULL LENGTH

CONTINUOUS SEAL WELDS IN ADDITION IN ADDITION TO ALL REQUIRED STRUCTURAL WELDS

TO NOT ALLOW MOISTURE INTRUSION.

WATER STORAGE TANK SYSTEM INCLUDING FINAL FINISHES AS INDICATED ON THE DRAWINGS AND SPECIFICATIONS.

UP-2: 'UNIT PRICES' FOR ALL CATEGORIES LISTED SHALL BE SUBMITTED WITH THE BID USING THE EXCEL SPREADSHEET PROVIDED. AFTER THE

CORROSION SURVEY RESULTS HAVE BEEN SUBMITTED BY THE CONTRACTOR AND REVIEWED THE CONTRACTING OFFICER (C.O.) , THE

QUANTITIES WILL BE UPDATED AND ADJUSTED ACCORDINGLY AT HIS SOLE DISCRETION OF THE C.O.

UP-3: 'UNIT PRICES' SHALL INCLUDE ALL MATERIALS, PREPARATION, FINISHES, LABOR, OVERHEAD, PROFIT AND ALL APPLICABLE BURDENS AND

CORROSION SURVEY:

CS-1: THE CONTRACTOR IS RESPONSIBLE FOR PERFORMING A DETAILED CORROSION SURVEY PRIOR TO PERFORMING ANY REPAIRS OR

REPLACEMENTS, OR ORDERING ANY REPAIR OR REPLACEMENT MATERIALS. THE FINAL CORROSION SURVEY SHALL BE SUBMITTED TO THE C.O.

FOR REVIEW AND USE AS OUTLINED BELOW.

CS-2: NOTE THAT THERE ARE MAY BE UNUSUAL ITEMS, WITH NO AVAILABLE SUBSTITUTES, THAT WILL REQUIRE SPECIAL MATERIAL ORDERS WITH

LONG LEAD TIMES.

CS-3: THE CORROSION SURVEY REPORT SHALL CLEARLY SHOW THE MAGNITUDE AND EXTENT (%) OF CORROSION AND LOCATIONS FOR ALL

INDIVIDUAL MEMBERS, CONNECTIONS AND RELATED HARDWARE THAT REQUIRE EITHER 'REPAIRS' OR 'REMOVAL AND REPLACEMENT'. THE

SURVEY SHALL INCLUDE DESTRUCTIVE INVESTIGATIONS IF/AS REQUIRED TO DETERMINE AND COMPARE THE ITEM TO THE APPLICABLE

THRESHOLDS REQUIRING EITHER 'REPAIR' OR 'REMOVAL AND REPLACEMENT'. THE SURVEY PHASE SHALL INCLUDE THE REMOVAL OF ALL LOOSE

CORROSION AS REQUIRED TO DETERMINE IF AN ELEMENT IS REPAIRABLE OR NEEDS TO BE REMOVED AND REPLACED, BUT DOES NOT ANY

PREPARATION FOR REPAIRS.

CS-4: THE CORROSION SURVEY RESULTS WILL BE USED BY THE C.O. AT THEIR SOLE DISCRETION, TO DETERMINE THE FINAL SCOPE OF WORK

AND DIRECT THE CONTRACTOR SPECIFICALLY WHICH MEMBERS ARE TO BE REPAIRED &/OR REMOVED AND REPLACED.

CS-5: REFER TO THE CORROSION 'WELD REPAIR THRESHOLD SCHEDULE' FOR TOLERABLE CORROSION LEVELS ON VARIOUS ELEMENTS.

CS-6: CORROSION SURVEY SHALL INDICATE LOCATION, ELEMENT, TYPE, EXTENT OF CORROSION AND ANY UNUSUAL FINDINGS FOR ALL

ELEMENTS REQUIRING EITHER REPAIR OR REPLACEMENT. THE SURVEY FORMAT SHALL TIE DIRECTLY INTO THE UNIT PRICE SCHEDULE AND ITEM

IDENTIFIERS INDICATED HEREIN.
