On May 2nd and 3rd, 2022, BB Industries hosted members of the ASTM International Committee C18 on Dimension Stone for their first in-person meeting of 2022. The group held meetings at the Knoxville, Tennessee headquarters in the morning, and afterwards traveled to visit area stone operations, such as the Tennessee Marble Company and quarry in Friendsville, Tennessee. 

Tennessee Marble Company (TMC) was formed in 1993 and extracts as well as manufactures high-quality dimensional stone for clients throughout North America. 

The ASTM members in attendance expressed their appreciation for BBI opening their facility to provide the needed meeting space, as well as technical support to be able to hold virtual meetings for other members not able to attend in person. The group also toured BB Industries’ facility and had a chance to ask the staff questions.

“The meeting space BB Industries provided for our Spring 2022 meetings was a priceless contribution to our committee’s activities… The top-notch audio-video equipment in your classroom space allowed us to interact with other members in places as remote as Australia,” — Kurt Hoigrad, Chairman, ASDTM Committee C18.
