Central Laboratory & Office Building / Nano-Phase Material
Sciences Building
Spallation Neutron Source Project at Oak Ridge
National Laboratory
Oak Ridge, Tennessee
Caddell, in joint venture with
Blaine Construction of Knoxville,
Tennessee, has completed three cutting-edge facilities for the Oak Ridge
National Laboratory -- this
agency’s largest contract award since the World War II-era
Manhattan Project.
The Target Building has been awarded major national construction
excellence awards including the ABC 2005 Excellence in Construction
Eagle Award, and the
AGC Build America Award.
The neutron-scattering research conducted at the SNS facility will have applications to
telecommunications, manufacturing, transportation, information technology, biotechnology,
and pharmaceuticals, and will be
available to users worldwide.
D/B
Hypersonic Testing Laboratory / Arnold AFB, TN
Caddell
performed the design/build of major upgrades and improvements to one of
the military’s primary aerospace ground testing facilities. This
conversion effort was required to enhance flight simulation conditions
to reflect the new realities of advanced “hypersonic” missile and
aircraft technology. Caddell made major modifications to a system of
compressed air tanks, the high-temperature/high-pressure burners that
use liquid oxygen to superheat the air blast, water-cooling systems, and
all associated instrumentation and controls. Caddell also rebuilt the
cylindrical test chamber itself,
increasing both its length and diameter.
These upgrades
provided the widest possible range of testing conditions for aerodynamic
and propulsion test customers. Caddell installed enhancements that
increased test simulation capabilities with air pressures up to 2,800
pounds per square inch and temperatures of up to 2,400 degrees
Fahrenheit; Mach 8 conditions. The improved APTU is only free jet test
facility with the capability to test advanced hypersonic air-breathing
propulsion systems over the entire flight range, from subsonic to Mach
8, for extended periods of time.

 Power Systems Testing &
Development Facility
Wilsonville, Alabama
Caddell has provided a wide range
of
equipment erection services for a unique
cutting-edge power systems development
and testing facility developed through a
partnership between the U.S. Department
of Energy, the Southern Company, and
various power industry equipment vendors.
The sophisticated R&D complex is
exploring new coal gasification
technologies designed to increase
the efficiency, cleanliness, and economic
viability of coal-based power.
Caddell has logged well over
1,000,000 MHs at
the Wilsonville facility with ZERO lost-time
accidents.
 Continuous Electron Beam
Accelerator Facility (CEBAF)
Project
Newport News, Virginia
This complex project
involved
construction of an underground
closed loop tunnel with ancillary
buildings for the CEBAF linear
accelerator. The scope of work encompassed excavation of an
open trench to construct approximately
4,600 LF of 10 ft. x 13.5 ft. rectangular concrete tunnel. Caddell also
completed construction of 16 steel-framed single-story structures ranging
in size from 210 SF to 13,000 SF.
