FOLSOM DAM - FIXED WHEEL GATE REFURBISHMENT
Folsom, Ca.
SCOPE OF WORK
C&W Diving was contracted to widen the slots for stop
logs in the penstock of Folsom Dam.
REQUIREMENTS
The C&W Crew was required to widen the slot in the
penstock by cutting a 2'x 4' beam using a diamond wire
saw then forming, installing rebar cages then placing
concrete to create a new structurally integrated beam to
support the designed slot width. 60'vertical scaffolding
and fall protection was utilized during this operation
as well as extesive containment procedures to prevent
foreign material inclusion into hydro electric
generating units. Post stop log placement underwater
work was performed to seal any leaks in the stop log
system.
PERIOD OF PERFORMANCE: 6 Months

AIMS ARTIFICIAL REEF PLACEMENT
Offshore Silverstrand, San Diego, CA
SCOPE OF WORK
C&W Diving Services, Inc. transported 85 Artificial
Reef Structures to the AIMS Range, offshore of
Silverstrand Beach San Diego. The Reef Structures were
placed on a 90’ x 21’ USN Causeway and towed by an LCM-8
vessel (M/V Elliot). C&W utilized a one-point anchor off
the stern of the vessel and tied off to the caisson
structure for movement. Structures were sent to the
bottom using an 8-ton crane mounted on the port side
wing wall of the M/V Elliot. The swell conditions were
not optimal (approximately 2-3 foot swells), so the
structures were lowered down and removed from the crane.
Later, divers attached lift bags to the structure for
accurate placement.
REQUIREMENTS
A representative from Merkel & Associates was aboard
C&W Dive Support Vessel (M/V Elliot) during placement
activities to verify placement. C&W was to place the
artificial reef structures on the scour mats and to
avoid placement which would prohibit channel and cable
installation. Due to rock overburden, some structures
were forced to be placed on the sand, outside of the
scour mats. Verbal approval was provided by Merkel &
Associates. All tasks were completed to customers
satisfaction in semi-rough swell conditions.
PERIOD OF PERFORMANCE: 2 days
