aeronautical ground lighting (AGL) systems.

Power Distribution Design

Low voltage through 600 Volt single and three phase systems; UPS, standby and emergency
generator design; medium voltage distribution design; inspections and renovations of existing
systems to correct National Electric Code (NEC) violations; ground testing; and ARC flash

Lighting Design

CRE holds licenses to use LITE-PRO, Visual, AGI-32, and Genesys II programs. Our use of this
software allows us to produce a lighting model that helps us optimize light distribution,
conserve energy, and maintaining safe light levels in public areas. Combined with our other CAD
software packages, we are prepared to perform any lighting design task to meet the projects
needs. Representative lighting projects types include: sports lighting; street lighting for major
and arterial roadways; pedestrian, parking lot, and garage lighting; interior and exterior building
lighting meeting the latest adopted City Building Codes, LEED, and standards for emergency and
egress lighting; theatrical lighting; and photometric testing.

Special System Designs

Fire alarm systems; security systems including CCTV, card access systems, laser and motion
detection, and motorized gates; and telecommunications using fiber optic technology.

Airfield Lighting and Control System Designs

CRE excels at technically complicated and specialized projects such as the electrical design of
aeronautical ground lighting (AGL) systems, including runway, taxiway, signage, PAPI and REILs.
We have substantial experience in this field of design as well as electrical design for additional
airport facilities. Our team members can provide power distribution design and sizing for
constant current regulators and other required vault equipment. We also have extensive
experience in designing AGL control and monitoring systems as well as standby systems.
