6. PROVIDE SAWN JOINTS OR CONSTRUCTION JOINTS IN SLABS AT ALL COLUMN

CENTERLINES AND AS SHOWN ON THE PLANS. SAWN JOINTS SHALL BE PROVIDED SO

THAT NO SLAB PANEL EXCEEDS 30 TIMES THE SLAB THICKNESS PER ACI

RECOMMENDATIONS. SAWN JOINTS SHALL BE CUT AS SOON AS POSSIBLE PER ACI

RECOMMENDATIONS.

7. FLOOR SLABS SHALL BE FINISHED TO A MINIMUM FLATNESS F-NUMBER, FF = 25 AND A

MINIMUM LEVELNESS F-NUMBER, FL = 20 IN ANY DIRECTION.

8. CONCRETE STRUCTURES MAY NOT SUPPORT THEIR DESIGN LIVE LOAD UNTIL THE

SPECIFIED COMPRESSIVE STRENGTH HAS BEEN ACHIEVED. LOADS GREATER THAN

THE DESIGN LIVE LOADS SHALL NOT BE PLACED ON THE STRUCTURE. THE

CONTRACTOR SHALL SUPPORT ADJACENT STRUCTURES, UTILITIES, AND EXCAVATIONS

AS REQUIRED FOR COMPLETION OF WORK.

CONCRETE, ALONG WITH SLUMP TESTS SHALL BE PERFORMED BY A TESTING

LABORATORY APPROVED BY THE STRUCTURAL ENGINEER.

10. ALL CONCRETE SHALL BE CURED IN ACCORDANCE WITH THE LATEST EDITION OF ACI

308, STANDARD SPECIFICATION FOR CURING CONCRETE. LIQUID CURING COMPOUNDS

SHALL BE COMPATIBLE WITH FLOORING ADHESIVES AND OTHER SURFACE

TREATMENTS AND SHALL BE APPROVED BY THE ARCHITECT PRIOR TO USE.

MASONRY:

1. ALL MASONRY AND GROUTING PROCEDURES SHALL BE IN COMPLIANCE WITH THE LATEST

EDITION OF THE BUILDING CODE FOR MASONRY STRUCTURES, ACI 530.

2. HOLLOW MASONRY UNITS SHALL BE GRADE N1 CONFORMING TO ASTM C90. SOLID

MASONRY SHALL BE GRADE N1 IN ACCORDANCE WITH ASTM C145 AND MAY BE 75% SOLID

UNLESS OTHERWISE NOTED.

3. MASONRY UNITS SHALL HAVE A MINIMUM COMPRESSIVE STRENGTH OF 2,000 PSI BASED

ON THE NET CROSS SECTIONAL AREA OF THE INDIVIDUAL BLOCK UNITS.

4. ALL MORTAR SHALL BE TYPE "S" MORTAR CEMENT CONFORMING TO ASTM C270 WITH

MINIMUM COMPRESSIVE STRENGTH OF 2,000 PSI AT 28 DAYS. ALL MORTAR JOINTS IN

MASONRY WALLS (HORIZONTAL AND VERTICAL) SHALL BE FILLED 100% WITH MORTAR.

5. ALL GROUT FOR VERTICAL REINFORCING AND BOND BEAMS SHALL BE 2,000 PSI MINIMUM

CONCRETE WITH SLUMP BETWEEN 8” AND 10”.

6. ALL CELLS CONTAINING REINFORCEMENT SHALL BE FILLED SOLIDLY WITH GROUT. GROUT

SHALL BE PLACED IN LIFTS OF 4’ MAXIMUM HEIGHT, UNLESS THE CONTRACTOR REQUESTS

AND OBTAINS APPROVAL TO PERFORM HIGH LIFT GROUTING. ALL GROUT SHALL BE

CONSOLIDATED APPROXIMATELY 5-10 MINUTES AFTER POURING AND BEFORE PLASTICITY

IS LOST BY VIBRATING. WHEN GROUTING IS STOPPED FOR ONE HOUR OR LONGER,

HORIZONTAL CONSTRUCTION JOINTS SHALL BE FORMED BY STOPPING THE POUR OF

GROUT NOT LESS THAN ½” BELOW THE TOP OF THE UPPER-MOST UNIT GROUTED.

HORIZONTAL STEEL SHALL BE FULLY EMBEDDED IN AN UNITERRUPTED POUR.
