INTRODUCTION
GUIDE SPECIFICATIONS FOR BRICK MASONRY
IV of V
ENGINEERED BRICK MASONRY
This issue of Technical Notes and the following issue, Technical Notes 11D, contain the required additional sections and statements to be incorporated into the "Guide Specifications for Brick Masonry", Technical Notes 11A Revised and 11B Revised. This will make the guide specifications in those Technical Notes suitable for Engineered Brick Masonry.
The sections contained in these Technical Notes deal primarily with the quality assurance, selection of units, strength and construction tolerances to provide masonry that meets the minimum design requirements for Engineered Brick Masonry.
In the construction of Engineered Brick Masonry, quality control may be maintained in either of two ways: (1) by testing the brick and controlling the mortar which can be done by laboratory tests or by mixing proportions, or (2) by periodic testing of masonry prisms. This Technical Notes covers quality control by method (1), testing brick and control of mortar. Technical Notes 11D covers quality control by method (2), testing masonry prisms.
When quality control by materials testing (brick and mortar) is to be used, the design compressive strength (f'm) can be assumed, using Table 2 of the SCPI Standard, "Building Code Requirements for Engineered Brick Masonry", and the quality control requirements of this Technical Notes should be incorporated into the guide specifications in Technical Notes 11A Revised and 11B Revised.
All other sections of the Guide Specifications for Brick Masonry (Technical Notes 11A Revised and 11B Revised) are appropriate for Engineered Brick Masonry.

PARTI-GENERAL
1.02 QUALITY ASSURANCE
Delete section and notes for 1.02.A in Technical Notes 11A Revised, and substitute the following quality control requirements based on brick tests.
A. Brick Tests:
1. Preconstruction Tests:
a. Test five brick for compressive strength to determine acceptability of units for compliance with specifications.
b. Use brick similar to those selected for use, matching color, texture, raw material, moisture content and coring.
c. Cost of tests shall be borne by the General Contractor.
2. Site Control Tests:
a. Test units selected at random from units delivered to the project.
b. Cost of tests of units after delivery shall be borne by the General Contractor, unless tests indicate that units do not conform to the requirements of the specifications, in which case cost shall be borne by the seller.
