FEBRUARY 2004 - JULY 2004
LAKE MEAD INTAKE No. 1 MODIFICATION
Boulder City, NV
SCOPE OF WORK
The contract required tie in of the existing water
intake for the city of Las Vegas from 100' to 170' of
water depth. The existing 12' diameter raw water
intake was prepared to receive a 10' diameter tee
section. A 12' diameter x 168' long mortar coated steel
pipe section weighing 180 tons was constructed on shore
and placed in the lake utilizing a critical lift plan
involving two 300-ton cranes. The pipe was towed to deep
water, where it was deployed utilizing a controlled
descent plan developed by C&W and naval architects. The
pipe was mated to a Carnegie joint section attached to
the tee section in 100 ffw. The lower end of the pipe
was set on a precast slab located at 170 ffw.
