Delaware Air National Guard Aviation Support Facility
Paragon Engineering provided HVAC, plumbing and electrical design for a new 23,256 SF Maintenance Hangar with 25,421 SF of Allied Shops and a new 31,600 SF Unheated Aircraft Storage Facility. The project also included 24,000 SF of renovations to an existing Hangar.
Project Overview
The Delaware Army National Guard (DEARNG) authorized the design of a new Army Aviation Support Facility (AASF) Add/Alt. to be located on New Castle County Airport, New Castle, Delaware. The scope of AASF was to construct an addition and renovation to the existing growing Army National Guard campus. The current facilities were inadequate to accommodate personnel and inadequate to house the fourteen UH-60 (Black Hawk) Aircraft and one C-12 fixed wing aircraft.
Project Features
It was the goal of the Delaware Army National Guard and the Design Team to achieve a LEED Silver Level for sustainable design and energy efficiency for the new components of this facility. The existing facility will also be improved for energy efficiency to the maximum extent practical.
Consideration for being operational during construction and renovation was a part of the design.
Project Cost
The project for the AASF Complex had a cost of $11 Million for the heated buildings, and $4 Million for the unheated buildings. Rebuilding the airfield located on this site required an additional $7 Million, for a total AASF Complex cost of approximately $22 Million.
Project Components
The new addition and renovated AASF Facility is approximately 92,000 square feet providing space for the administration, maintenance and operation of the Black Hawk Helicopters.
Heated Buildings
Components of the new Army Aviation Support Facility include utilization of the existing 4-bay hangar and two-story office/shop area as well as the addition of a new 4-bay UH-60 hanger and associated two-story administrative /shop area.
Unheated Buildings
An unheated 34,000 SF Aircraft Storage Hangar will accommodate UH-60 Aircraft so as to allow weather protection for the entire assigned fleet of Black Hawk Aircraft.

The office and maintenance space was heating and air conditioned by two air handling units using a hot water coil and direct expansion cooling coil with remote outdoor condensing units. The hanger was heated using an under floor, hot water radiant heating system to provide comfort to the mechanics maintaining the plane and an overhead gas-fired infrared heater system for general purpose hanger heating. Hot water for heating was provided by a gas-fired boiler.
An oil separator and waste oil tank was designed for the hanger floor drainage system. The waste oil tank design included a leak detection system. A 15,000 gallon, underground jet fuel storage tank, double wall fiberglass distribution piping and a refueling module was also provided for aircraft fueling. Exterior to the building an underground lift station was designed to provide sanitary drainage. A safety shower and eyewash was provided for the maintenance shop.
A secondary service was provided for the facility by the Power Company by means of a primary overhead electrical service and a secondary transformer. An electrical room was designed to house power and lighting distribution panels including power to the electrical operated hanger doors. High bay, quartz re-strike, pendant mounted, metal halide lightning fixtures where used to light the hanger area. Standard fluorescent fixtures where used to light the office space and maintenance facility.

Flight Safety International
Paragon Engineering provided HVAC, plumbing, Fire Protection and Electrical design for this new two-story facility consisting of two large Simulator Bays housing up to seven (7) Flight Training simulators, a 2300 SF Computer Room, twelve classrooms, a Tech Library, a pump room and other support spaces. The building was heated and cooled by a water source heat pump system and distribution ductwork. The building included a dedicated outside air unit to ensure proper outside air quantities in accordance with applicable codes and maintain good indoor air quality. The cooling tower for the existing building and the cooling tower for the new addition were designed to be piped together with manual valves to allow selected equipment to serve the two buildings to maintain a reduced level of heating and/or air conditioning in the event of the failure of one tower. Hydraulic piping from the Pump Room to the simulators was routed in a trench in the floor with an accessible cover. Heat pumps were provided to serve the interior cooling for each simulator unit via flexible ductwork to allow free movement of the simulator unit during training.
