NOTE: SD-04: On small projects 300 by 300 mm (12
by 12 inch) samples will be sufficient. On large
projects utilizing complex or many large panels, a
full-size mock-up may be required and should be
specified.

SD-04 Samples
Precast Concrete Units[; G][; G, [_____]]
[Two 300 by 300 by 50 mm 12 by 12 by 2 inch samples of each type
of precast unit finish required for the project. Samples shall
show matrix color, surface color, surface texture, and panel back
finish.] [A full-size mock-up, maintained at the precast concrete
manufacturer's plant until approval by the Contracting Officer for
removal or incorporating in the project. The mock-up shall be
used to establish quality and acceptance of precast units to be
used on the project, and shall consist of three or more units,
showing the exterior finish (matrix color, surface color, surface
texture), panel back finish, edge treatment, joint treatment,
reinforcement, anchorage insert, lifting inserts, and other
accessories. Mockup shall also include [doors and windows] [and]
typical joints, including exterior corner joints and joints
between units].
SD-06 Test Reports
Materials
Certified copies of test reports including all test data and all
test results. Tests for compressive strength of concrete shall be
performed by an approved independent commercial testing
laboratory, except that compressive strength tests for initial
prestress may be performed in the manufacturer's plant laboratory.
1.3
GENERAL REQUIREMENTS
Precast concrete units shall be designed and fabricated by an experienced
and acceptable precast concrete manufacturer certified under the PCI Plant
Certification Program. The manufacturer shall have been regularly and
continuously engaged in the manufacture of precast concrete work similar to
that indicated on the drawings for at least 3 years. The Contractor shall
submit a statement detailing the Manufacturer's Qualifications as specified
in the Submittals paragraph. Precast work shall be coordinated with the
work of other trades.

Standards and Loads
**************************************************************************
NOTE: Design loads will be shown on the drawings.
Criteria for design loads are contained in ASCE 7
and EI 01S010. The differential temperature of 89
degrees C (160 degrees F) is based on extreme values
of 40 degrees C (40 degrees F) below zero to 49
degrees C (120 degrees F) above zero; it should be
