The Quarry still maintains the facade of the cement factory and its most notable feature and landmark is the four historical smokestacks that can be seen several miles from the Quarry. In 1998 Tramell Crow brought in structural restoration and preservation specialist, Delta Structural Technology, Inc. to restore and preserve three of the four stacks. The structures are approximately 204 ft high, and 18 ft diameter at the base and, 15 ft diameter at the top. These smokestacks had previously been retrofitted with steel bands every 20 ft. from top to bottom, which had either rusted and fallen off or had relaxed providing little, if any structural confinement. The structural contractor utilized an exclusive retrofit technique which involved complete encapsulation of three of the four stacks using high performance structural composites saturated in an epoxy matrix. The installation took less than two months, and received multiple awards within the Historical Preservation and Concrete Construction industry.
