Cades Cove Off-Grid Solar Power System
CROFT conducted a solar energy study and full engineering design for a remote, off-the-grid 36kW solar photo-voltaic power system linked to an existing battery bank and gas powered generator system at the Historic Cades Cove recreation area in the Great Smoky Mountains National Park, a protected landscape identified as a UNESCO World Heritage Site.
After a national search by the NPS in Denver, CROFT was selected to lead the technically complex process of integrating a fully off-the-grid solar photovoltaic system as the third power supply element in a legacy battery-bank and gas generator system. After a solar study and load analysis that identified a need for 30% larger system than originally projected, CROFT led the electrical, civil, and landscape architectural design to site the solar array while carefully screening it from historically significant site amenities at the Cable Mill Visitor’s Center.
The solar array provide a silent energy source to serve the small visitor center, bookstore, and restroom facility in the Cable Mill area. The panels are located behind the restroom in an area that receives maximum exposure from both morning and afternoon sun. A low berm planted with native vegetation was created around the array to minimize the visual intrusion on the historic landscape and the area’s natural beauty. The array consist of 80 panels and occupy a 40 by 65-foot area.
The project reduced greenhouse gas emissions by 23 tons and fuel costs by $14,000 annually. Prior to development of this solar power system, the park used an aging diesel-fueled generator and battery backup system for electric power at the site. Not only was this diesel system costly and labor-intensive to operate, but caused noise disruptions to park programs and impacted the visitor experience at this remote historic landscape.

USACE Mobile District
Carter's Lake Operations Facility
CROFT provided full A/E design, fire protection, and construction administration services to support the construction of a 2,400 SF secure document storage facility and a 750 SF power house building addition for the USACE Mobile District. The project included a large dedicated secure storage space, work areas equipped with full data connectivity, restroom facilities, mechanical room, and power generation support space designed to conform with both LEED Silver and AT/FP standards.
Deliverables included preliminary site assessment, cost estimate, specifications, constructability review to coordinate the integration of a steel-framed addition into an existing live generator facility, and construction administration including RFI and submittal review, shop drawing review/approval, construction monitoring, and inspections.
NPS Ocmulgee Visitor Center Renovation
CROFT conducted a needs assessment and full A/E design services for the roof and terrace replacement for the 26,000 SF historic "Art Modern" Visitors Center at the Ocmulgee National Monument in Macon, Georgia.
The design included complex multi-phased demolition, renovation, and drainage system remediation for nine roof sections and a 3,152 SF terrace roof that protects the oldest Native American artifacts in the National Park Service, dating to the Paleo-Indian Period of 3,000 to 10,000 BC.
USACE Savannah District
US Army Intellegence and Security Command SCIF
Fort Gordon, GA
CROFT and its design teammates conducted a facility investigation, design charrette, full architectural/engineering design, specifications, and RFP preparation to support the conversion of a conventional administrative building into a Sensitive Compartmentalized Information Facility (SCIF) Command Center for US Army Intellegence and Security Command at Fort Gordon, GA.
The project included facility assessment, cost estimating, HVAC system retrofit, electrical, fire protection, lighting, doors, floors, walls, interior and exterior finish modifications, sound control, anti-terrorism force protection measures, and electronic communications protection.
The raised floor facility included a SCIF conference room, controls room, and state-of-the-art video conferencing capabilities.
