Roof Replacement at Carroll Middle School Wins ACEC/NC 2002 Honors Award

The American Council of Engineering Companies of North Carolina presented MACTEC with a 2002 Honors Award for the roof replacement project at Carroll Middle School in Raleigh. The award represented engineering excellence in building and technology systems.

During the initial field investigation for the school's replacement roof design, MACTEC discovered significant deterioration of the existing concrete fill and metal form deck. The adequacy of the existing deck for the new roof was questionable, and costly deck repair would likely have been required.

In response to this concern, MACTEC developed a unique design to replace the existing roof with a retrofit standing seam metal roof system. The system avoided placing additional roof loads on the deteriorated deck, and used the existing structural framing to support the retrofit metal roof. This innovative design accommodated the roof replacement without modifying, strengthening or replacing the deck, and resulted in project completion under budget, on schedule, and with minimal disruption to school activities.
