GK Engineers, LLC provided full mechanical, electrical, and plumbing (MEP) design services for the new two-story, 12,000-square-foot InSouth Bank facility in Jackson, Tennessee. The project included complete site work and ground-up construction designed to meet modern banking operations while maintaining efficiency, reliability, and comfort. All MEP design services were performed in accordance with local codes and standards established by the Authority Having Jurisdiction and the State of Tennessee.

The mechanical design featured a Variable Refrigerant Flow (VRF) system as the basis of design, offering a flexible and energy-efficient solution capable of supporting the building’s diverse thermal requirements. GK Engineers performed detailed load calculations to determine precise heating and cooling capacities for the building’s offices, customer service areas, and support spaces. The VRF system was selected to provide individualized zone control, enabling efficient temperature regulation while minimizing energy consumption. Complete HVAC drawings suitable for permitting and construction were prepared in coordination with the architectural layout to ensure proper duct routing and equipment placement.

The electrical design encompassed comprehensive power distribution, lighting, and standby power systems to support the bank’s operational and safety needs. A new electrical service and distribution system were designed to meet the facility’s load requirements, including branch circuits for HVAC, lighting, and plumbing equipment. 

Interior lighting design was coordinated with the architect and owner to integrate energy-efficient fixtures that align with the architectural aesthetic and comply with applicable energy codes. Exterior and site lighting, including façade illumination, were incorporated to enhance visibility and security. The electrical design also included provisions for a natural gas (NG) generator to ensure continued operation of essential systems during power interruptions.

The plumbing design included new domestic water, sanitary sewer, and storm drainage systems to serve the entire facility. GK Engineers designed the domestic water service and branch distribution to connect seamlessly with site utilities, with the service line extending 5 feet beyond the building footprint for coordination with the civil engineer. Hot water was distributed through a central system equipped with a recirculation loop to provide consistent and efficient service throughout the building. The sanitary system was designed to route all building wastewater to the municipal connection outside the building, ensuring proper flow and compliance with local code requirements.

In addition, GK Engineers provided the design for the fire service entry and developed delegated design specifications for the fire protection system, which was to be finalized by a specialized contractor. All MEP construction documents were produced in AutoCAD or Revit per the architect’s request and prepared to be suitable for permitting and bidding.
