Scope of work
Note:
This informative Annex has been written in mandatory language to facilitate adoption by anyone wishing to do so.
B.1 General
B.1.1
The owner’s specifications shall include all items that are to be included in the contract documents for the
precast concrete work.
Note:
The owner should stipulate that the general contractor provide the name of the precast concrete subcontractor in the
tender documents for each project involving architectural and structural precast concrete.
B.1.2
Transportation to and installation at the job site of the precast concrete elements shall be the responsibility
of the precast concrete manufacturer and executed by the manufacturer’s employees or by a qualified
specialist firm acting as subcontractor to the precast concrete manufacturer.
Note:
Exemption from responsibility for delivery and/or installation may be made for small precast elements such as window
sills, lintels, stair treads, benches, covers, pavement slabs, and specialty items. Other exemptions may be made where the
usage of concrete products ties in with other site operations not controllable with respect to scheduling by the precast
manufacturer, such as the incorporation of precast elements into masonry work.
B.1.3
Items relating to other trades shall be described in the precast concrete specifications and in the other
related trade sections.
Note:
The general inclusion or exclusion of specific items has been outlined in this Annex so that early budget estimates
supplied to the owner can be judged on a more uniform basis. The owner should clearly outline which items are to be
included for bidding purposes. These will depend on the individual job, local trade practices, and the precast manufacturer’s
recommendations.
B.1.4
The cost of any specified materials testing and/or inspection, beyond the cost of the manufacturer’s quality
control required by this Standard, shall be the responsibility of the owner. The manufacturer shall provide,
at no extra cost, all materials required for testing and allow inspectors reasonable access to the
manufacturer’s premises.
B.1.5
The owner shall specify procedures for the submission of shop drawings for review, including the number
of prints required of the installation (or layout) drawings, setting drawings for contractor’s hardware,
drawings of all installation details, and drawings of all typical elements.
Note:
Submission of production shop drawings may be limited to typical elements.
B.2 General contractor’s work
B.2.1
A schedule of installation shall be mutually agreed upon between the precast manufacturer and the
general contractor.
