SPALL REPAIR NOTES:

1. SELECT THE APPROPRIATE SPALL REPAIR DETAIL AFTER COMPLETING DEMOLITION

OF DETERIORATED CONCRETE. CONFIRM WITH THE ENGINEER

1.1. USE SPALL REPAIR TYPE1 FOR SURFACE REPAIRS NOT GREATER THAN 1"

DEEP AND REBAR IS NOT EXPOSED

1.2. USE SPALL REPAIR TYPE 2 FOR REPAIRS GREATER THAN 1" DEEP OR WHERE

EXISTING REINFORCING IS EXPOSED.

1.3. A GREATER SPALL REPAIR MAY BE REQUIRED WITHIN THE AREA OF A

LESSER REPAIR.

2. UTILIZE SPALL REPAIR DETAILS WHERE THE CONCRETE IS GENERALLY GREATER

THAN 12" THICK. WHERE MEMBERS EXHIBIT GREATER THAN 25% SECTION LOSS,

NOTIFY THE ENGINEER

3. SQUARE OFF DETERIORATED CONCRETE TO SOUND CONCRETE WITH A SAWCUT OF

4" MINIMUM TO 1" MAXIMUM BUT NOT TO THE DEPTH OF THE REINFORCING STEEL.

BACK BEVEL EDGE OF REPAIR AREA BEYOND SAWCUT.

4. USE HAND TOOLS TO REMOVE LOOSE AND DELAMINATED CONCRETE TO PROVIDE A

SOUND BOND BETWEEN EXISTING CONCRETE AND NEW REPAIR MATERIALS.

DEMOLITION HAMMERS WITH IMPACT RATINGS OF 16 FT/LB OR LESS MAY BE USED IF

REQUIRED. PROVIDE A MINIMUM 34" THICK REPAIR.

5. IF DEPTH OF DETERIORATED CONCRETE EXTENDS BEYOND THE PRIMARY

REINFORCEMENT, REMOVE THE CONCRETE TO A LEAST 34" BEHIND THE

REINFORCEMENT.

7. CLEAN EXISTING REINFORCEMENT BY MECHANICAL MEANS. NOTIFY ENGINEER OF

DETERIORATION OF THE REINFORCING, ADDITIONAL DIRECTION MAY BE REQUIRED.

8. APPLY AN EPOXY BONDING COMPOUND BETWEEN THE EXISTING CONCRETE AND

NEW REPAIR MATERIAL.

9. USE DOWELS ONLY WHEN THE LEAST DIMENSION OF THE PREPARED REPAIR AREA

IS LESS THAN 2'-0", OR WHEN NEW REINFORCEMENT CANNOT BE ADEQUATELY

DEVELOPED BY LAPPING WITH THE EXISTING REINFORCEMENT.

10. INSTALL DOWELS WITH AN ADHESIVE ANCHORING SYSTEM PER THE

MANUFACTURERS RECOMMENDATIONS. USE HILTI HIT-HY 200-A HYBRID MORTAR,

OR EQUAL.

GENERAL NOTES:

1. CONTRACTOR IS RESPONSIBLE TO VERIFY ALL DIMENSIONS IN FIELD

2. SUBMIT PRODUCT SPECIFICATIONS, SAMPLES, INSTALLATION

INSTRUCTIONS/METHODS, ETC. FOR REVIEW AND APPROVAL PRIOR TO THE START

OF WORK.

3. ALL MATERIALS INSTALLED INSIDE THE CLEAR WELL BASINS, OR OTHERWISE

EXPOSED TO DRINKING WATER SHALL BE NSF 61 APPROVED.

4. PROVIDE ALL NECESSARY EQUIPMENT, LABOR, AND MATERIALS, INCLUDING

FORMWORK, LIGHTING, VENTILATION, AND SCAFFOLDING OR OTHER ACCESS

SYSTEM NECESSARY TO COMPLETE THE WORK.

5. SEE 03930 CONCRETE REPAIR & REHABILITATION SPECIFICATION FOR REPAIR

MATERIAL REQUIREMENTS

6. REINFORCING SHALL CONFORM TO THE FOLLOWING STANDARDS

6.1. DEFORMED BARS: ASTM A615

6.2. WELDED WIRE FABRIC: ASTM A185

7. CONTRACTOR SHALL MAINTAIN HIS OWN LOG OF ACTUAL QUANTITIES OF EACH

REPAIR TYPE FOR REVIEW BY THE PROJECT MANAGER.

8. CONTRACTOR SHALL COMPLETELY REMOVE EXISTING SURFACE COATINGS,

SEALANTS/SEALANT SYSTEMS, EPOXY, ETC., IF PRESENT, FROM THE AREA TO BE

REPAIRED OR INJECTED.

DECK REPAIR NOTES:

1. SELECT THE APPROPRIATE DECK REPAIR DETAIL AFTER COMPLETING DEMOLITION

OF DETERIORATED CONCRETE. CONFIRM WITH THE ENGINEER.

1.1. USE DECK REPAIR TYPE 1 FOR SURFACE REPAIRS NOT GREATER THAN T/2

DEEP WHERE REBAR IS NOT EXPOSED.

1.2. USE DECK REPAIR TYPE 2 FOR REPAIRS NOT GREATER THAN T/2 DEEP

WHERE EXISTING REINFORCING IS EXPOSED.

1.3. USE DECK REPAIR TYPE 3 WHERE REPAIRS EXCEED T/2 DEEP.

2. DECK REPAIRS DETAILS ARE TYPICAL FOR REPAIRS MADE FROM TOP-SIDE OR

UNDERSIDE OF ROOF DECK AND INTERMEDIATE FLOOR, OR OTHER LOCATIONS

WHERE MEMBERS ARE 12" THICK OR LESS.

3. SQUARE OFF DETERIORATED CONCRETE TO SOUND CONCRETE WITH A SAWCUT OF

4" MINIMUM TO 1" MAXIMUM,BUT NOT TO THE DEPTH OF THE REINFORCING STEEL.

BACK BEVEL EDGE OF REPAIR AREA BEYOND SAWCUT.

4. USE HAND TOOLS TO REMOVE LOOSE AND DELAMINATED CONCRETE TO PROVIDE A

SOUND BOND BETWEEN EXISTING CONCRETE AND NEW REPAIR MATERIALS.

DEMOLITION HAMMERS WITH IMPACT RATINGS OF 16 FT/LB OR LESS MAY BE USED IF

REQUIRED. PROVIDE A MINIMUM 34" THICK REPAIR.

5. IF DEPTH OF DETERIORATED CONCRETE EXTENDS BEYOND THE PRIMARY

REINFORCEMENT, REMOVE THE CONCRETE TO A LEAST 34" BEHIND THE

REINFORCEMENT.

7. CLEAN EXISTING REINFORCEMENT BY MECHANICAL MEANS. NOTIFY ENGINEER OF

DETERIORATION OF THE REINFORCING, ADDITIONAL DIRECTION MAY BE REQUIRED.

8. APPLY AN EPOXY BONDING COMPOUND BETWEEN THE EXISTING CONCRETE AND

NEW REPAIR MATERIAL.

9. USE DOWELS ONLY WHEN THE LEAST DIMENSION OF THE PREPARED REPAIR AREA

IS LESS THAN 2'-0", OR WHEN NEW REINFORCEMENT CANNOT BE ADEQUATELY

DEVELOPED BY LAPPING WITH THE EXISTING REINFORCEMENT.

10. INSTALL DOWELS WITH AN ADHESIVE ANCHORING SYSTEM PER THE

MANUFACTURERS RECOMMENDATIONS. USE HILTI HIT-HY 200-A HYBRID MORTAR,

OR EQUAL.
