Sandy, The company I work with, Willis Construction Co.(sorry, gotta plug us), manufactures about $5M worth of GFRC each year at our San Juan Bautista, CA plant and about $15M worth of architectural and structural precast. We've been producing GFRC since 1983. Third party inspectors provide periodic inspection on maybe 10% of our GFRC projects, at most. There is no UBC inspection requirement. Special inspection is provided at the discretion of the owner. Mr. Philip Iverson, Technical Director of the Precast Concrete Institute, may be able to provide you with more information. PRECAST/PRESTRESSED CONCRETE INSTITUTE 175 W. Jackson Blvd., Suite 1859 Chicago, IL 60604 Phone: 312-786-0300 Fax: 312-786-0353 Email: info(--nospam--at)pci.org http://www.pci.org/ Our plant is PCI certified for the production of GFRC, architectural and structural precast products. Using/specifying PCI certified producers is the most practical means of confirming that a manufacturing plant has a satisfactory and ongoing quality assurance system in place. With this program the plant must consistently demonstrate their commitment to quality principles and practices. A 120-point audit examines all aspects of plant operation including engineering practices and management commitment. We "wet" test daily for skin thickness, slurry unit weight, and spray rate. We fabricate test boards daily and perform wash-out tests. Wash-out testing determines the average glass fiber content of the backing mix. Our post-curing tests include face and backing mix strengths, flex anchor/bonding pad pull-off and shear tests. Naturally, all of our testing is on going, never ending, process. We send out our bonding pad test specimens and test board flexural strength specimens for testing by an independent test lab. The test results tests are used to statistically determine our plant's unique design values so that my designs are based on data that represents the actual performance we are achieving. For this same reason, it is imperative that specimens are prepared daily for each project, as a part of regular production, by production personnel so that the results reflect what is actually happening in the shop. We are also an ICBO Certified GFRC fabricator (FA-353)and an approved City Of LA Certified Fabricator (License 1413) of GFRC and precast concrete products. Our experience, qualifications, and quality control and assurance program promotes a level of confidence to a degree that most owners elect not to spend money on third party inspection of the work performed at our plant. I believe the money is probably best spent at the jobsite to ensure the panels are installed per the erection details and specifications. Regards, Brent Koch, P.E. Willis Construction Company Inc.
