engineering services of the kind indicated. Engineering services are defined as those performed for installations of architectural precast concrete that are similar to those indicated for this Project in material, design, and extent.
Participates in PCI’s Plant Certification program at the time of bidding and is designated a PCI-certified plant for Group A, Category A1- Architectural Cladding and Load Bearing Units.
Has sufficient production capacity to produce required units without delaying the Work.
Delete subparagraph below if fabricators are not required to be registered with and approved by authorities having jurisdiction. List approved fabricators in Part 2 if required.
Is registered with and approved by authorities having jurisdiction.
Retain first paragraph below if PCI Certification Program provides quality assurance testing, and additional quality assurance testing is required. Testing agency is normally engaged by Owner.
Insulation Manufacturer’s Qualifications:
Provide shop drawings and detailing for concrete wall insulation system.
Attend pre-construction meetings and initial wall panel insulation placement to instruct in the proper installation of the wall panel system.
Provide quality assurance instruction and equipment for evaluation of connector installation.
Provide traceable and verifiable quality assurance by a recognized third party testing agency.
Listing requirements vary with product; however, all require that the manufacturers established testing and evaluation procedures must be repeatable and open to third party review and verification. Wythe connectors should be evaluated for the following:
Material hardness per ASTM D 785-89
Material flexural capacity per ASTM D 790-86
Also as part of the listing process, connector samples should be subjected to shear, pullout, and fire tests. Shear and pullout tests were both monotonic and cyclic. These tests are conducted to verify that the connectors are capable of maintaining their capacity in extreme seismic and fire events.
Testing Agency Qualifications: An independent testing agency, [acceptable to authorities having jurisdiction] qualified according to ASTM C 1077 and ASTM E 329 to conduct the testing indicated, as documented according to ASTM E 548.
Design Standards: Comply with ACI 318 (ACI 318M) and the design recommendations of PCI MNL 120, “PCI Design Handbook – Precast and Prestressed Concrete,” applicable to types of architectural precast concrete units indicated.
Quality-Control Standard: For manufacturing procedures and testing requirements, quality- control recommendations, and dimensional tolerances for types of units required, comply with PCI MNL 117, “Manual for Quality Control for Plants and Production of Architectural Precast Concrete Products.”
