AIRFIELD ELECTRICAL IMPROVEMENT PROJECTS: Innovations in a Low Bid Environment “Net Zero” Objective Considerations: How is “Net Zero” Achieved? By reducing Operations and Maintenance costs (Energy) By producing energy from the airfield environment … topic for another day. How is this Accomplished in a Low Bid Environment? By improving understanding of airfield electrical system design By improving project scoping and contracting relative to airfield electrical system design requirements Net Zero through Emerging Technologies2 MILITARY DESIGN GROUP Delta Airport Consultants, Inc

AIRFIELD ELECTRICAL IMPROVEMENT PROJECTS: Innovations in a Low Bid Environment Base Utilities Electrical Distribution Overview: Definition of Electrical Power Power = Voltage x Current (Watt = Volt x Amp) Two Electrical Power Delivery Modes Constant Voltage – Voltage remains constant and the current fluctuates based on the load demand (Typical voltages – 120, 208, 240, 277, 480) Constant Current – Current remains constant and the voltage fluctuates based on the load demand Net Zero through Emerging Technologies3 MILITARY DESIGN GROUP Delta Airport Consultants, Inc

AIRFIELD ELECTRICAL IMPROVEMENT PROJECTS: Innovations in a Low Bid Environment Examples of Constant Current Based Systems: Airfield Electrical Systems Very few others due to strict performance requirements (an aircraft hydraulic control system which operates at 4,000 psi provides a good analogy) Net Zero through Emerging Technologies5 MILITARY DESIGN GROUP Delta Airport Consultants, Inc

AIRFIELD ELECTRICAL IMPROVEMENT PROJECTS: Innovations in a Low Bid Environment Scoping Disconnect: 95% + of all electrical projects on a military installation are constant voltage based. Understandably, the project methodology associated with these systems is often applied to the airfield electrical system. However, what is desirable in the “constant voltage” world is often counterproductive in the “constant current” world of the airfield electrical system. The misapplication of design methodology can result in energy waste and unsafe working conditions for maintenance personnel Net Zero through Emerging Technologies6 MILITARY DESIGN GROUP Delta Airport Consultants, Inc

AIRFIELD ELECTRICAL IMPROVEMENT PROJECTS: Innovations in a Low Bid Environment SOLUTION: Improve the Project Scoping Process 1)Review the components of the airfield electrical system and understand the corresponding stakeholder requirements. 2)Explain the most common type of disconnects associated with airfield electrical system projects 3)Illustrate how scoping an airfield electrical system project from an O&M perspective supports the mission and the concept of “Net Zero” Net Zero through Emerging Technologies7 MILITARY DESIGN GROUP Delta Airport Consultants, Inc
