Lee Harrell has over 35 years of experience in all aspects of electrical engineering and project management for healthcare, educational, commercial, industrial, institutional, and laboratory facilities Lee developed our Visual and Virtual Reality Design processes as well as our ISO 9001-compliant Quality Assurance Process. Lee also designed, coded, and copyrighted DesignGear, the first of its kind engineering software application to fully integrate drawing data with automated design calculation and drawing production tools. This system allows the delivery of design documents in significantly less time and with better quality. Lee is a Qualified Commissioning Process Provider and a LEED Accredited Professional. Lee was an initial member of the Alliance for Interoperability, whose work led to the development of the single model concept which is the basis of BIM applications such as Revit.


Dramatically improving the results of your design and construction projects, and the current operation of your facilities.

Design, operation, and maintenance of facilities is more demanding than ever. Accelerated construction schedules, escalated construction costs, tighter requirements, and increased attention to infection control, indoor air quality, mold, etc., can challenge the best facility. Harrell Design Group, PC was formed to help facilities meet these challenges through management, planning, design, and commissioning of large and small additions, renovations, and new projects. We also retro-commission existing facilities and even help facilities with day-to-day operations and maintenance. We can dramatically improve the results of your construction projects, and the current operation of your facilities.
