circuit. The corridor contained the magnetic
starter for the motor generator sets, the portable
lighting equipment, and the service power receptacle. A common battery-type island telephone was wall-mounted in the corridor.

Station 1610 was provided by modifying
and adding to REDWING Station 3020. This
afforded a clear room space in the formerstation
DESIGN PSI:
enclosed with copper screening around the wall
perimeter, two User-furnished motor generator
sets, portable outlet receptacles, lights, and signal panel. Outside the former station wall to the
south, a re-inforced concrete tunnel maze termi-
nated at an entrance blast door. Wing walls
retained earth barricade fill areas surrounding
the tunnel. Two 24-inch-OD steel pipes were
provided through the station south end wall
under the barricade fill to provide ventilation
air from an air-conditioning unit situated in a
new Mechanical Equipment Room 30 feet from
the station. The Mechanical Equipment Room
was of wood frame construction, 15-foot-square
in plan, 10 feet high, with a 4-inch concrete floor
slab, exterior plywood sheathing, and flat roof
with built-up composition roofing. A concrete
slab area, fenced with wood posts andrails, ad-
joined one end of the Mechanical Equipment
Room. A Trigger House of wood frame construction, 4-foot-square in plan by 4% feet high
was also provided and was situated 10 feet off
the line of sight between Stations 1310 and 20.
A 4-inch conduit run extended from Station
1610 to the Trigger House for coaxial cable.
Power was obtained from the 4160-v, 3phase, 60-cycle island power distribution system
by tapping the 3°'C+25-kv cable which passed
this location.
The Mechanical Equipment Building con-
tained the following electrical equipment: Signal Terminal Cabinet, Telephone Terminal
Cabinet Panel “PA” and Panel “LA.” Panel
“PB” was mounted outside on the South Wall.
The main station structure consisting of
the corridor and the Instrumentation Room
contained the following: The Instrumentation
Room had two 20-kw motor generator sets, Userfurnished. The entire room was copper screen
shielded with special enclosure about the motors
of the motor generator sets. This room was the
terminus of the fourteen %-inch aluminum-

A re-inforced concrete detector structure
and two segments of six.radial pipelines comprised this station. The pipelines diverged from
a radial center at the Station 20 work point and
terminated at the detector structure wall. The
lines of the first segment terminated at a retaining wall approximately 242 feet from the
Detector Station. Thence, beginning at a re-
taining wall separated by 4 to 5 feet from the
first wall, a segment of six radial pipelines extended to a retaining wall 17% feet distant
from the work point of Station 20. The first
segment of pipe was supported on a vertical
steel plate and post detail at intervals throughout its length. One edge of the plate was anchored to a retaining wall also on a radial alignment and adjacent to the lagoon-side pipe; the
other edge was supported by a steel post on a
concrete footing pad. The second segment of
the pipelines was supported on a steel upright
extending from a transverse steel beam and
post frame detail supported on concrete spread
footings. Spacing of the support frames was 15
feet. The pipeline segments were buried in fill
throughout their lengths.
The Detector Station provided a room space,
2924 feet long, 3 feet wide, and a 61%4-foot
ceiling height. The foundation slab was 2 feet
thick, the north wall toward Station 20 was
4 feet thick, other walls were 1% feet thick,
and the roof slab was 2 feet thick. The structure
had an 814-foot-deep earth fill barricade over
the roof. Access to the Detector Room was
through a wood frame tunnel over a concrete
floor having plywood sheathing over wall studs
and roof joists. The six pipelines terminated 12
inches inside the north wall face. The wall section was blocked out to form a 2-1/6-foot-square
opening, 3 feet long at the end of each pipeline,
and the perimeter surrounding the walls of the
blockout section were lined with 1-inch-thick
micarta. Three rows of convex-shaped lead brick
were placed to fill the opening against the pipes.
