A.3 Responsibility of the manufacturer
A.3.1 Design capability
A.3.1.1
A manufacturer producing precast concrete elements in accordance with this Standard shall have
established design capability.
A.3.1.2
The responsibilities of the manufacturer’s engineer in relation to the owner shall be established in the
contract documents (see
Table A.1
).
A.3.1.3
The manufacturer’s engineer shall be responsible for preparing and obtaining the owner’s review of shop
drawings and installation drawings (see Clauses 1.2 and 16.3 of CAN/CSA A23.3) and for translating the
requirements for each project into procedures that will allow the finished project to be of the required
quality.
A.3.1.4
The manufacturer shall be responsible for the following design items, if applicable:
(a) design of all loading conditions for precast concrete elements;
(b) shop drawings, layout, connection details, and related calculations (see
Clause A.3.3
);
(c) design of structural precast concrete elements; and
(d) design for loads for handling, transportation, and installation.
A.3.1.5
The manufacturer shall be responsible for the following items during the preparation of shop drawings,
the fabrication of precast concrete elements, and the installation of precast concrete elements, if
applicable in accordance with this Standard:
(a) design, protection, and location of lifting hardware;
(b) modifications to reinforcement and hardware;
(c) conduits, pipes, wiring, and/or other appurtenances or fixtures embedded in the precast concrete;
(d) determination of the stripping strength of the concrete;
(e) curing procedures;
(f) establishment of concrete strength for shipping; and
(g) assessment of structural damage and repairs.
A.3.1.6
The manufacturer shall clearly identify the owner’s fire-rating requirements and verify that the design and
shop drawings contain materials and details sufficient for attaining these ratings (see
Clause 14.6.3
).
A.3.1.7
The manufacturer shall review the design of all precast concrete elements designed by others for structural
soundness and feasibility with respect to applied loads, finishes, connections, handling stresses, joint
treatment, and tolerances, both for manufacturing and installation. Any deficiencies shall be reported to
the owner.
Note:
This review should not be interpreted as relieving the owner of any applicable responsibilities (see
Table A.1
).
