The AAS team provides detailed CAD drawings to explain how to install the architectural cast stone.
The settings plan describes drawings for different sections with specific description to hang the stone. Customers get comprehensive installing planning support and drawings that show how to attach every stone panel to be used in the project. This is integrated in the AAS methodology for the project specific custom fabrication of the architectural stone products.
The AAS team is able to provide design assist to the architect and contractor for a project. The in-house engineering support team develops detailed attachment connections that will achieve the design objectives.
The shop drawings will provide the architect and installer an opportunity to review the attachment and make the final detailing.
General Rules for attachment
GFRC pieces up to about 4 feet x 6 feet can often be produced without an additional structural back-up. The manufacturer will add a stiffener-rib to the product back side for added support. A stiffener usually runs the height of the piece every 24 to 30 inches of the product and has very concentrated glass fiber to cement mix. The product can be attached via a veneer tie and strap, kerf and clip, or similar attachment to the structure of the building.
Larger pieces or pieces where a stiffener-rib is not appropriate are generally hung with a metal stud back-up. The metal stud system is designed and attached to GFRC piece by the manufacturer as part of the cost of the GFRC on the project. Metal stud back-up is very similar to metal stud framing on most commercial projects, but designed with more precision. The metal stud back-up is usually attached with a grade #2 bolt to the structure of the building. There are occasions where the metal stud framing is welded to the structure. Again the specifications on the welding should follow AWS (American Welding Society) standards.
Very large pieces (larger than 8 feet x 20 feet) will have tube steel back-up. The process is much the same as with metal studs discussed above. This back-up will be engineered by AAS.
AAS is able to provide type of connection that is preferred by customer. GFRC provides flexibility with selection of the connection type.
Once the connections are selected, the AAS manufacturing and design process is able to pre-engineer the connections support in the products.
GFRC is much simpler and less expensive to install compared to other much heavier stone products. GFRC installation doesn’t require extensive support structure and heavy construction equipment at the project site.
AAS GFRC products provide flexibility to select right application of caulk or sealants making it easier for masonry contractors not only in their installation process, but also with long term reliability of the installed projects.
The AAS design and engineering process includes details for installation anchorage to confirm the final design aesthetic in the initial review, design assist process. With detailed drawings and coordination with masons and contractor, installation completes very smoothly.
This project also show how cast stone and GFRC can be combined with seamless color matching opening up opportunities for simplified construction, value engineering, and at the same time unparalleled design freedom.
GFRC products have pre-engineered, built in connections that simplifies the onsite installation.
See in this video, examples of drawings and images of products being installed at the SMU Delta Gamma Sorority House project.
AAS has bandwidth and a well developed system to work closely with architects, contractors and masons for every project. Installation support details are designed with intent of not only realizing architect’s desired design vision, but also simple, easy installation.
As required, project team works with customers in selecting combination of products that would achieve design cost effectively.
