Locally owned and operated, GreyStone Power is a not-for-profit organization dedicated to providing reliable electric service to eight counties across northwest Georgia. The power company relocates its corporate campus to a spacious site. While the entirety of the property spans more than 80 acres, the campus occupies just shy of 50 acres of the grounds, with the remaining areas left as natural, undisturbed green space and ponds. The natural landscape surrounding the building provides employees with a place to connect with nature and recharge during their workday.

To incorporate the campus within the existing landscape, construction plans were designed and executed around the wetlands and lakes, leaving more than 10 beaver dams untouched.

As the administrative and office buildings on the campus required a longer construction duration than the warehouses, the team crafted a detailed site logistics plan organizing the critical path of execution to prioritize and schedule accordingly. The project was on a tight deadline to meet the needs of GreyStone’s relocation, so foresight into potential delays required proactively looking at weather conditions and developing and executing plans to overcome them. In order to continue working through the rainy and winter seasons that often bring mud and mess to the jobsite, the project team constructed temporary roads composed of soil cement just below the grade of the future permanent roads. Not only did this allow the project to continue smoothly, it also cut cost for the project by dramatically limiting the use of temporary stone pathways – pathways that need to be replaced frequently as they sink and settle into the soil.  The temporary soil cement pathways were left in place and provided a stronger foundation for the campus’ permanent long-term roadways.

The administration building houses a credit union and corporate services, including three stories of administrative offices, conference rooms, board rooms, and additional office space. A tilt-up building houses GreyStone Power’s operations and engineering services, plus supervisory control and data acquisition (SCADA) operations.

Additionally, a 50,000-SF tilt-up warehouse is constructed with 61,000SF of coverage canopy around the perimeter of the building. The canopy is installed to protect GreyStone Power’s service vehicles from damaging storms, ensuring they are available to respond in case of a power outage. A pre-engineered metal building for vehicle maintenance operations is also constructed, along with pole storage, and a covered walkway between buildings.

To support the vehicle fleet, a multi-lane fuel station allows for double the number of trucks to fill up in critical situations compared to the previous facility, so emergency response teams can get back on the road and help restore power to their communities.
