3.1. SEE SPECIFICATIONS SECTION 03 30 00 - CAST-IN-PLACE

CONCRETE.

4. SLAB-ON-GRADE

4.1. TAKE PRECAUTIONS TO MINIMIZE SLAB CURLING. GRIND SLAB

OR USE LEVELING COMPOUND IF FLOOR FLATNESS AND

LEVELNESS VALUES ARE NOT ACCEPTABLE TO THE

7. REINFORCING FABRICATION

7.1. SPLICES:

7.1.1. NO SPLICING OF REINFORCEMENT PERMITTED EXCEPT AS

NOTED ON DRAWINGS. MAKE BARS CONTINUOUS AROUND

CORNERS. WHERE PERMITTED, SPLICES MAY BE MADE BY

CONTACT LAPS OR MECHANICAL CONNECTORS.

SPLICES ARE TO BE MADE SO THAT GIVEN CLEAR

DISTANCES TO THE FACE OF CONCRETE WILL BE

MAINTAINED.

SEE 'LAP SPLICE SCHEDULE' FOR LAP LENGTHS.

7.2. HOOK EMBEDMENT NOTES

7.2.1. SIDE COVER IS 2 1/2 INCHES OR GREATER

7.2.2. COVER BEYOND IS 2 INCHES OR GREATER

7.2.3. IF SIDE COVER IS LESS THAN 2 1/2 INCHES, INCREASE

LENGTHS BY 40%

8. PLACING REINFORCEMENT

8.1. PLACE REINFORCEMENT IN ACCORDANCE WITH APPROVED

REINFORCEMENT SHOP DRAWINGS. IN THE EVENT OF A

CONFLICT BETWEEN THESE DRAWINGS AND THE APPROVED

SHOP DRAWINGS, THE APPROVED SHOP DRAWINGS SHALL

GOVERN.

8.2. SEE ACI 318-14 26.6 AND ACI 301, SECTION 6.3 FOR

REINFORCEMENT PLACING TOLERANCES AND ACI 117 FOR

ADDITIONAL REQUIREMENTS.

8.3. THE FIRST AND LAST BARS IN SLABS AND WALLS, AND

STIRRUPS IN BEAMS ARE TO START AND END AT A MAXIMUM OF

ONE HALF THE ADJACENT BAR SPACING. ALL REINFORCING TO

BE EQUALLY SPACED UNLESS OTHERWISE SHOWN ON THE

DRAWINGS.

8.4. WHERE POSSIBLE, REINFORCEMENT SHALL BE PLACED TO

MAINTAIN A CLEAR DISTANCE OF AT LEAST 1 INCH BETWEEN

OTHER REINFORCEMENT, ANCHOR BOLTS, FORM TIES, OR

OTHER EMBEDDED METALWORK. REINFORCEMENT PARALLEL

TO ANCHOR BOLTS OR OTHER EMBEDDED METAL WORKS

SHALL BE PLACED TO MAINTAIN A CLEAR DISTANCE OF AT

LEAST 1-1/3 TIMES THE MAXIMUM SIZE AGGREGATE TO BE

USED.

8.5. REINFORCEMENT PROTECTION:

8.5.1. SEE 'CONCRETE COVER TABLE'

8.5.2. SEE ACI 318-14 26.6 FOR REINFORCEMENT PLACING

TOLERANCES AND ACI 117 FOR ADDITIONAL

REQUIREMENTS.

8.6. PROVIDE ACCESSORIES NECESSARY TO PROPERLY SUPPORT

REINFORCING AT POSITIONS SHOWN ON PLANS. ALL

REINFORCING, DOWELS, BOLTS, AND EMBEDDED PLATES SHALL

BE SET AND TIED IN PLACE BEFORE THE CONCRETE IS POURED.

"STABBING" INTO PREVIOUSLY PLACED CONCRETE IS NOT

PERMITTED.

8.7. PROVIDE ADDITIONAL BARS OR STIRRUPS REQUIRED TO

SECURE REINFORCING IN PLACE DURING CONCRETE

PLACEMENT.

8.8. REINFORCEMENT MAY BE ADJUSTED IN THE FIELD TO CLEAR

FORM TIES AND ANCHOR BARS. IN SUCH CASES, RELOCATION

OF THE EMBEDDED MATERIALS MUST BE CONSIDERED. IN NO

CASE SHOULD BARS BE BENT IN THE FIELD.

9. MISCELLANEOUS REINFORCING REQUIREMENTS:

9.1. MAKE ALL REINFORCING BAR BENDS IN THE FABRICATOR'S

SHOP UNLESS NOTED.

9.2. NO WELDING OF REINFORCING PERMITTED UNLESS NOTED ON

DRAWINGS. WHERE PERMITTED, PERFORM WELDING IN

ACCORDANCE WITH AWS D1.4, LATEST EDITION.

9.3. PROVIDE ADDED REINFORCING TO TRIM ALL OPENINGS,

NOTCHES, AND REENTRANT CORNERS AS NOTED IN TYPICAL

DETAILS.

10. CONSTRUCTION/CONTROL JOINTS

10.1. SUBMIT DRAWINGS SHOWING CONSTRUCTION AND CONTROL

JOINT LOCATIONS ALONG WITH THE SEQUENCE OF

PLACEMENTS. CONSTRUCTION JOINT LOCATIONS AND CASTING

SEQUENCE SHALL BE ARRANGED TO MINIMIZE THE EFFECTS OF

ELASTIC AND LONG-TERM SHORTENING.SHRINKAGE. NO OTHER

JOINTS SHALL BE INTRODUCED UNLESS APPROVED BY THE

CONTRACTING OFFICER OR CONTRACTING OFFICER

REPRESENTATIVE BEFORE CONCRETE IS PLACED.

10.2. CONTROL JOINTS SHALL CONFORM TO DETAILS PROVIDED ON

DRAWINGS. IMMEDIATELY BEFORE THE SECOND CONCRETE

PLACEMENT, THE PROJECTING HALF OF THE DOWEL SHALL BE

GREASED TO PREVENT BOND TO THE CONCRETE.

10.3. CONSTRUCTION JOINTS IN SLABS-ON-GRADE, AND STRUCTURAL

SLABS SHALL BE LOCATED TO ACCOMMODATE THE MAXIMUM

LENGTH AND AREA THE CONTRACTOR CAN REASONABLY POUR,

FINISH AND JOINT IN THE SAME DAY.

10.4. SHEAR FRICTION JOINTS: WHERE CONSTRUCTION JOINTS ARE

LABELED AS "ROUGHENED" ON THE DRAWINGS, THE ENTIRE

JOINT SURFACE SHALL BE MECHANICALLY ROUGHENED TO A

1/4" AMPLITUDE AND THOROUGHLY CLEANED. EXPOSE THE

COURSE AGGREGATE IN THE HARDENED CONCRETE AND

REMOVE ALL LOOSE MATERIAL.

11. FINISHING

11.1. SEE SPECIFICATIONS SECTION 03 30 00.

11.2. UNLESS OTHERWISE INDICATED, CHAMFER EDGES OF ALL

PERMANENTLY EXPOSED CONCRETE SURFACES WITH A 45

DEGREE BEVEL, 3/4 INCH X 3/4 INCH. CHAMFER STRIP MAY NOT

BE SHOWN ON THE DRAWINGS.

12. MEP AND OTHER OPENINGS AND EMBEDMENTS:

12.1. PROVIDE SLEEVES AT OPENINGS (SUCH AS THOSE REQUIRED

FOR PLUMBING AND ELECTRICAL PENETRATIONS) BEFORE

PLACING CONCRETE. DO NOT CUT REINFORCING WHICH MAY

CONFLICT. CORING OF CONCRETE IS NOT PERMITTED.

12.2. REFER TO TYPICAL DETAILS FOR SPACING LIMITS ON SLEEVES

AND FOR REQUIREMENTS FOR EMBEDDED CONDUIT AND PIPE.

SPLICE SCHEDULE NOTES

1. 'LCE' COMPRESSION EMBEDMENT LENGTH, 'LCS' = COMPRESSION

LAP SPLICE LENGTH, 'LDH' = HOOK DEVELOPMENT LENGTH, 'LTE' =

TENSION EMBEDMENT LENGTH, 'LTS' TENSION LAP SPLICE LENGTH.

2. 'TOP' BARS ARE HORIZONTAL BARS PLACED WITH MORE THAN 12

INCHES OF FRESH CONCRETE IS CAST BELOW THE BAR.

3. ALL SPLICES SHALL BE WIRED IN CONTACT AND STACKED

VERTICALLY.

4. ALL SPLICES ARE 'LTS' UNLESS NOTED OTHERWISE.

5. SMALLER BAR LAP LENGTH SHALL BE USED WHEN SPLICING

DIFFERENT SIZED BARS.

6. LAP LENGTHS SPECIFICALLY DETAILED ON DRAWINGS SHALL

GOVERN IN LIEU OF LAP LENGTH SCHEDULE.

7. SCHEDULE LAP LENGTHS ASSUMPTIONS:

7.1. CLEAR COVER IS GREATER THAN BAR DIAMETER, AND NOT

LESS THAN 3/4".

7.2. CLEAR SPACING BETWEEN BARS IS GREATER THAN 2 BAR

DIAMETERS.

7.3. IF EITHER CONDITION ABOVE IS NOT MET FOR A GIVEN BAR,

INCREASE LENGTH BY 50%.

8. SPLICE LENGTHS NOTED BASED ON FY = 60,000 PSI. FOR OTHER

YIELD STRENGTHS, MULTIPLY SPLICE LENGTHS NOTED BY FY/60,000.
