Prefabricated
Masonry Panels
The MCAA acknowledges with gratitude the contributions of time and effort by members of the Masonry Panel Committee and their consultants. These recommendations are the consensus of this Committee, composed of Fred Daues, chairman, Jack Bailey, Dee Brown, L. C. Pardue, Jr., Turner Smith, Sherman Smoot and William Vetovitz. The Committee believes that the methods and procedures recommended in this document are important elements in the successful completion of masonry panel projects.
SECTION 04235
1.00 GENERAL
A. The General Conditions, any Supplementary General Conditions, and Division 1. General Requirements, are hereby made a part of this Section as fully as if written herein.
1.01 SCOPE
A. Furnish all material, labor, equipment, engineering and incidentals for prefabrication and installation of "Prefabricated Masonry Panels" as shown on the Drawings and in accordance with these specifications.
B. Included in this work, but not limited to, are the following items:
1. Integral steel frames, masonry ties, reinforcing bars, anchoring clips and attachment devices to supporting structural framing system.
2. Bolts, lifting devices, etc., for handling and for installation of panels and as required for anchoring of other items as shown on the Drawings.
3. Providing openings, installing built-in items, etc., as specified in other sections of the Specifications.
4. Masonry units, including special shapes and sizes, mortar, grout, etc.
1.02 QUALITY ASSURANCE
A. Contractors wishing to bid "Prefabricated Masonry Panels" shall submit to the Architect the ability to meet these Specifications, no later than 15 days prior to the date for receipt of bids. In judging the following submittals, the decision of the Architect shall be sole and final.
1. Panel Manufacturer must demonstrate proficiency in prefabrication, handling, transportation and erection of "Prefabricated Masonry Panels" and submit evidence of successful experience and ability to perform.
2. Panel Manufacturer must have qualified and experienced personnel for continuous quality, handling, transportation and erection of "Prefabricated Masonry Panels."
3. Panel Manufacturer shall be responsible for the structural design and reinforcing of "Prefabricated Masonry Panels" and its components to resist all loads due to handling, transportation and erection.
4. Panel Manufacturer shall possess factory-like environment with adequate space, equipment, financing, etc., to produce "Prefabricated Masonry Panels" of required quality and to conform with the project progress schedule.
5. Panel Manufacturer shall submit calculations with shop drawings to the design Architect or Engineer of record.
CAVEAT-These guidelines are for general recommended practices and may not be applicable to a particular project. Independent research should be undertaken by the installing contractor.
1.03 DESIGN CRITERIA
A. Panel Manufacturer shall be responsible for structural design of "Prefabricated Masonry Panels" in accordance with design criteria established by design architect and structural engineer and shall ensure that the panels shall:
1. withstand lateral loads, both wind and seismic,
2. withstand all loads incurred by handling, storage, transportation and erection, without forming tension cracks, and
3. satisfy all applicable requirements of the local building code.
B. Lifting devices shall have an ultimate capacity of four times the dead weight of the appropriate portion of the panel. Inclination of the lifting forces shall be considered.

1.05 QUALITY CONTROL TESTING
A. A Testing Laboratory, selected and paid for by the Architect, shall test specimens of masonry prisms, mortar cubes and grout cylinders for quality control, as defined herein, and provide special inspection if required.
B. Panel Manufacturer shall supply brick, mortar, grout, etc., to the Testing Laboratory representative.
C. If the relation between 7 and 28 day strengths of such specimens has been established prior to commencement of work, submit test evidence to the Architect and the following tests may be performed for 7 days aging only.
1. PRISMS: Masonry compressive strength shall be checked for every 5,000 square feet of panel arca by testing small unreinforced assemblages, representative of the full size panel. Three prisms of one brick unit in length and thickness and at least twelve (12) inches in height shall be assembled, cured for 7 days and tested per procedures outlined in Building Code Requirements for Engineered Brick Masonry, recent publication.
