of the construction documents … and I’m sure this is hardly
the way our construction founding fathers intended the
process to play out.

end there is one unavoidable and undeniable common

wonder if they’re hiring? n

WAKE WATCH GUIDELINES
When a shore crane is used o hoist work onto floating
equipment, or when a floating derrick is hoisting onto a
land based structure or another barge there is potential for
passing boat traffic to have a safety impact. Movement
due to the wake can catch workers off guard with serious
potential. If the operation has obvious potential for injury
or equipment damage an employee shall be designated
as spotter to watch for any wake producing marine traffic.
“NO WAKE ZONE” signage should be used if conditions
dictate at the work site.
Keep proper navigation lights in place on buoys, barges,
and bridge structures. Maintain proper notice to mariners.
Be aware of private vessels transiting the area. Be prepared
to call vessels via VHF radio and give them five blasts on the
air horn if they are entering the work zone. Posting signs on
the deck of barges is the proper way to warn the public of
submerged anchor wires or other hazards and warn them
to stay clear – 500 feet. Posting of “Construction Zone” signs
should also be used to warn the general boating public of
jobsite hazards. n

* As a rule of thumb, start with a shade that is too dark to see the weld zone. Then, go to a lighter shade which gives a sufficient view of the weld zone
without going below the minimum. During oxygen gas welding or cutting where the torch produces a high yellow light, it is desirable to use a filter lens
that absorbs the yellow or sodium line in the visible light (spectrum) of the operation.
** Values apply where the actual arc is clearly seen. Lighter filters may be used when the arc is hidden by the workpiece.

THE ALL NEW SHEET PILE DRIVER FROM NPK
NPK’s all new excavator-mounted sheet pile
driver is a modified design of industry leading
plate compactors, adapted to direct powerful
vibration forces downward, optimizing driving
of sheet pile. Durable, shock-absorbing rubber
mounts protect the excavator’s boom and stick
from vibration and shock loading. The mobility
and maneuverability of NPK sheeting drivers
permit operation in many areas previously
inaccessible: under low clearance obstructions
(bridges, etc.), around bridge piers, and next
to walls. This makes picking up, moving and
aligning the sheeting easy and stress-free
when driving and/or extracting. Designed for
Key Features and Benefits
• 180° free rotation allows precise alignment and positioning of the sheet
pile without having to reposition the machine. When not needed the swivel
can be locked into place; either parallel or perpendicular to the boom.
• Dedicated top mounting brackets, designed to OEM bucket specifications,
provide a full range of motion when picking up the sheeting from the
• Simple operation means that any excavator operator can easily drive and
• Clamp fitted with a hydraulic cylinder lock to prevent slippage.
• Shock-absorbing rubber mounts isolate vibration and reduce noise.
• Heavy duty, high efficiency gear motor.
• Integrated flow control and pressure relieving valves protect from
excessive flow and pressure.
• Oil splash lubrication eliminates routine greasing of the bearing.
