DESCRIPTION
TRANSCRIPT
Husqvarna’s new WS 440 HF is setting a new standard for electric high cycle wall saws. The saw is based on a totally new technology, which gives the saw increased power for fast and efficient sawing. The powerful, water-cooled electric motor generates 17 horsepower to the shaft, despite the fact that the saw only weighs 55 pounds. The 9,000 rpm permanent magnitized motor delivers 100% power to the blade while cutting concrete or steel.
Husqvarna has succeeded in optimizing the weight/power relationship and developed a saw that is light and flexible but also powerful!
The NEW WS 440 HF Wall Saw.

B eginning in the mid-1980s, industries became
concerned with the projected mass retirement
of the baby boomers. the major question be-
hind this issue was, “what will happen when this excep-
tionally large segment of our work force is no longer
around to produce the goods and services required to
sustain our economy?” even though today’s economic
environment may cause some baby boomers to post-
pone their retirement plans, many will still leave the
workforce within the next five to ten years.
when i look at the people who make up the commit-
tees, board and officers of csDA, i see a sprinkling of
people from my generation, sometimes known as the
silent generation or the “matures” but i see many more
baby boomers in the ranks. some represent the second
generation of their family business as csDA members.
with them comes a legacy of enthusiasm and desire
to make a meaningful contribution to the association.
Many have been contributing their time and leadership
to the association for most of their careers.
other new board and committee members have
been in the sawing and drilling business a relatively
short time, but they already recognize the benefits
of accepting leadership roles as board and commit-
tee members. these new, younger members carry
forward the experience, knowledge and values of
previous generations, adding to that a fresh perspec-
tive and technological savvy that can greatly benefit
our industry.
tom stowellCSDA President
the make-up of our committees and board offi-
cer positions closely mirrors our membership. Because
the membership base of csDA will also be affected
when the baby boomers begin retiring, membership
growth is an especially critical issue. we need newer
members to begin providing more leadership to ensure
the future success of csDA benefits and programs for
a new generation of members.
therefore, i would like to extend an invitation to
our younger contractor members to sit in on a commit-
tee meeting or two. At the very least, you will learn
more about csDA and make a few new friends. At
most, you will see the value csDA programs bring to
your business and you’ll want to participate in the
leadership of csDA to influence the future of those
programs.
truly, the size of your company doesn’t matter.
our members represent companies of all sizes. what
matters is your willingness to step up and see what your
peers are doing to improve the concrete sawing and
drilling industry. so, come and join us at one of our
quarterly meetings. i promise you a warm welcome and
i‘m certain you’ll find the experience both educational,
fun and worth the effort.

l ocals have nicknamed the Victoria Memorial Museum Building
(VMMB) the “castle” because of its scottish baronial style. Home
to the canadian Museum of nature, this historic building in
canada’s capital is undergoing a long-awaited restoration. the project
will update every system in the castle and create 22,000 square feet of
additions. crews will also return to the building something that was
lost long ago—its signature entrance tower.
Architect David ewart designed the building at the turn of the 20th
century. ewart’s design incorporated a towering front entrance to pay
homage to canada’s parliament building. scottish masons traveled
Core Drilling the Castle
To save one of Canada’s oldest and most beloved buildings, CSDA

across the Atlantic to prepare the local sandstone for the VMMB, and
construction began in 1905. seven years later, the national Museum of
natural sciences (now the canadian Museum of nature) displayed its
first exhibits at the VMMB’s grand opening.
By 1915, signs that the foundation could not support the VMMB’s
weight could not be ignored. cracks were appearing in the founda-
tion and the massive entrance was tearing away from the building.
the castle was sinking. construction crews shortened the tower by 80
feet in an effort to stabilize the structure. Further stabilization efforts
were made throughout the 20th century, including the castle’s last major
renovation in the 1960s.

today’s rehabilitation project is expected to end the castle’s long-
time foundation problems. the most important improvement is the
seismic framing system, a new steel frame that is being built directly
into the existing walls and floor, then tied to the stonework. in essence,
construction crews will create an endo-skeleton, or a building within a
building, for the VMMB.
crews are dry drilling the walls to create access for the seismic frame
installation. Dry drilling is necessary because the walls are constructed of
sandstone, a very porous rock that would be damaged by wet drilling.
the seismic frame will provide enough support to restore ewart’s origi-
nal design intention. the castle’s towering entrance will be re-created,
but this time the structure will be made of glass. the tower includes a
giant lantern, creating a sparkling draw for passersby as well as bright-
ening the interior of the museum for its patrons.
over 4,350 feet of dry drilling was required on this project. general
contractor pcL constructors canada (pcL) called in csDA member
company capital cutting and coring (capital) because of their estab-
lished reputation of experience, teamwork and performance. concrete
sawing and drilling is generally chosen on jobs that require precision.
sawing and drilling are also fast, efficient and cost-effective alternatives
to demolition. Because the VMMB is a historic landmark, maintaining
the structural integrity of the building makes precision concrete work
like capital’s a valuable commodity. pcL also took into account capital’s
proven ability to work in areas open to the public, keeping debris and
dust contained.
capital’s team began their work at the west entrance of the VMMB.
they erected scaffolding outside the structure to provide safety and
access to the walls and roof. capital and pcL established regular safety
meetings early on to keep everyone on top of safety and site cleanliness
issues. capital chose a Diamond tech drill, the Dt401, 110 volts with
tB 50-torque booster to drill 6 holes, 4 inches in diameter and 35 feet
deep. operators used specialized K-2 Diamond bits, and kept the bits
cool during drilling with compressed air.
Because operators were drilling into a porous rock, they encoun-
tered voids that made removing the cores more difficult than usual. they
also ran across sections that had been filled with grout and loose rock.
often these voids would jam up the drill and pulverize the core. work
progressed slowly as capital’s crew extracted the troublesome cores.
coring the west entrance eventually took close to 14 weeks.
the team moved on to the west chimneys with the Dt401. work
consisted of 4 holes, 4 inches in diameter and 22.5 feet deep. Fortunately,
the chimneys were solid. there were only two complications the crew
had to manage: maneuvering the Dt401 into very tight spaces in order
to access the chimneys and drilling through a 1-inch-thick steel web at
their base. work on the chimneys went smoothly for the crew.
After completing the west entrance and west chimneys, capital
drilled test cores on their future work sites to learn the extent of the
voids and debris within the sandstone. the east and west chimneys
were completely solid, but the east entrance and main entrance were
full of inconsistent rock and grout as well as voids, much like the west
entrance. the main entrance was a concern because it constituted the

capital cutting & coring used a portable 8x10 steel platform to ensure that the Beretta t43 was perfectly level while core drilling the delicate sandstone.

bulk of their work. it was also a high-profile job, as the work there would
make way for the project’s signature feature, the glass lantern tower.
to core 48 holes at a depth of 75 feet on schedule would require more
specialized equipment than capital had in inventory.
capital researched several options. A few drills fit the bill, but only
one could be delivered in any reasonable amount of time: the Beretta
model t43, manufactured in italy. capital also special-ordered 5.5 inch,
5-foot-long casings with a numa hammer for the Beretta. As soon as the
Beretta t43 was delivered, capital’s team began training on the drill.
once trained, the crew set up scaffolding and misting fans at the
main entrance. capital installed a portable, heavy-duty, 8 x 10 foot, steel
platform to ensure that the Beretta was perfectly perpendicular to the
drilling surface. capital chose to use safe, biodegradable lubricants for
the drill and hydraulic power pak. not only would they avoid harm-
ing the 100-year old sandstone if a hose burst, but the fluids would be
totally harmless to the environment as well.
capital’s team began drilling with the Beretta t43 and slowed the
drill down to limit debris spray. the crew core-drilled 48 holes, each
5.5 inches in diameter and 75 feet deep. All of their careful planning,
training and preparation paid off. capital completed the main entrance
without incident. capital decided to use the Beretta for the rest of the
job. After they had completed the holes at the main entrance, seismic
anchors were installed and grouted in 3-meter sections lifts.
inclement weather conditions often made working impossible. the capital crew had to endure sub-zero temperatures as well as snowfall in excess of 190 inches.

Methods Used: Core Drilling
Moving to the east entrance, they set up the scaffolding and
prepared to drill 6 holes, 4 inches in diameter and 35 feet deep. capital
worked expertly through the voids, grout and loose rock at this entrance.
the severe canadian winter, however, was more difficult to manage.
one hundred-ninety inches of snow fell during that winter, causing
intermittent delays. when the capital team was able to work, it was
in biting sub-zero temperatures. even so, the crew completed the east
entrance on schedule.
Finally, capital set up their scaffolding at the east chimneys. they
were still working in freezing temperatures and difficult-to-maneuver
spaces. the chimneys also had a 1-inch steel web at their base, but
capital was able to core drill the 4 holes without incident. Just like the
west chimneys, these holes were 4 inches in diameter and 22.5 feet
deep. After finishing their work on the east chimneys, capital’s job at
the VMMB was complete.
Due to the age and size of the building, the VMMB restoration
project posed very unique problems. sandstone made the use of water
impossible; voids encountered in the walls required the purchase of
and training on a new drill necessary; consideration had to be taken
for keeping dust down and keeping construction areas contained since
the museum was open for the duration; and severe weather conditions
including 190 inches of snow made working on the historic building
extremely challenging. capital made safety a priority, using safety
resources from csDA and pcL’s safety group at regular meetings, and
was able to overcome the obstacles that presented themselves through
careful planning, research and on-the-job flexibility. ■
A new, removed entrance was created for visitors to the museum while the main entrance underwent construction, including the 75-foot holes capital was drilling for the seismic brace.

denver international Airport (diA) is the
largest airport in the united states by
land mass. situated on 34,000 acres
just 30 minutes northeast of denver proper, the
airport has over 6 million square feet of public
space and has recently surpassed los Angeles
international to become the country’s 4th busiest
airfield. to keep up with the rising demands of
being a top international hub, diA has begun its
first major concourse expansion project.
constructed to replace Denver’s landlocked stapleton airfield in
1995, DiA was designed for efficiency and growth. passengers are
screened in a central location and transported by rail system from DiA’s
Jeppesen terminal, named for aviation safety pioneer elrey Jeppesen, to
one of three concourses. the airfield is arranged in a pinwheel formation
around the terminal and concourses, creating an independent flow of
aircraft to and from each runway without overlap. taxiways are posi-
tioned to allow the expansion of each concourse as necessary.
DiA’s first concourse expansion is a 3-year, $160 million project that will
add 8 new gates to the eastern end of the concourse. part of the expansion
calls for the installation of 4 moving walkways to ease traffic flow through
the concourse. in order to install the walkways, construction crews would
have to cut 4 large sections of 7-to 8-inch-thick concrete with pan decking.
And, each 160-by15-foot section would have to be removed while the
concourse remained open to passenger traffic.
general contractor pcL constructors (pcL) called in veteran csDA
member company DeAndrea coring and sawing, inc. to get the job
done. pcL chose DeAndrea because of the company’s reputation for
clean, efficient concrete cutting in high-traffic areas.
DeAndrea carefully planned the job. they researched pedestrian
traffic in the area as well as the structure of the floor, sub-floor and
lower levels. Because the concourse had been designed with the inten-
tion of expansion, a sub-floor had been built where the future walkways
would be. these sub-floors were shorter than the intended walkways by
20 feet on each end, which allowed room for the concrete to be lowered
into the pit for removal. DeAndrea’s team would have to use a gantry
Cutting ConcreteBefore denver international Airport could add four moving walkways to Concourse C, deAndrea Coring and sawing had to clear close to a million pounds of concrete from the existing floors.

crane to work on the floating floor sections, and harnesses would be
a necessary safety precaution. to limit issues with airport patrons, they
decided to work at night, when the number of passengers would be at
a minimum. pcL had already established a 10-foot tall barrier to keep
pedestrian traffic contained away from the construction site.
Before DeAndrea could begin work on the concourse, the team
members had to receive security clearance. each worker was finger-
printed and background-checked. paperwork, screenings and security
classes required by clearance took an average of two weeks per person
to complete.
Meanwhile, other construction delays meant DeAndrea’s work would
have to wait a full week before startup. when the team was allowed
access to the work site, several operators were still awaiting their security
clearance. DeAndrea did not want to risk losing more time, so the team
moved forward to start the job short handed. DeAndrea’s other crew
members would join the team as their clearance came through.
the DeAndrea team set up plastic protection around the section to
be cut in the concourse and the pit to guard the areas from slurry and
dust. they secured crew harnesses to either the steel structure or gantry
crane using rope and clips. once the materials, equipment and safety
measures were in place, they chose to use a 20-inch terra blade with a
30-hp, 460-volt Meco 30M electric slab saw to begin cutting. Because
this first section had no sub-floor, crew members used a 1-ton aluminum
gantry crane to chain hoist the concrete. the crane was anchored in with
a 2-point pick using 5/8-inch wedge anchors and eye nuts.
the team worked to cut a section measuring 28 feet by 15 feet out
of the floating floor area in 7-foot by 30-inch pieces, lowering them with
the gantry crane to the waiting forklift and exposing the 20-foot steel
i-beam support below. when they lowered the first piece of concrete,
an unexpectedly strong updraft blew debris and slurry up from the pit.
the crew began working to contain the updraft. Laying plastic over the
gaps proved ineffective. the updraft even blew through concrete blan-
kets. Finally, the team was able to contain the updraft by placing a roll
of heavy plastic on each side of the walkway, then carefully unrolling
the plastic while securing it with 2 x 4s as they moved forward.
for Concourse C
plastic, concrete blankets and 2 x 4s were progressively used to contain the updraft from blowing slurry mist into the concourse area.

THE WHITE TENSION FAbRIC ROOF WAS DESIGNED by LEO A. DALy TO LOOk LIkE THE SNOW-CAPPED ROCky MOUNTAINS.
Architecturally, DiA’s most visually
appealing feature is its white tension
fabric roof. the roof was designed
by architect Leo A. Daly to reflect the
snow-capped rocky Mountains to the
west. steel cables similar to those on the
Brooklyn Bridge support the roof. Also
highlighting the mountains is a pedestrian
bridge that extends from the terminal to
concourse A, where passengers can watch
planes taxi directly beneath them and
enjoy sweeping views of the rockies.
once they had exposed the i-beam support,
the crew unbolted it from the surrounding
steel structure and subfloor, crossed-wrapped
it with chain and used the gantry crane to
twist it at a 45 degree angle, lowering through
the pit area to the lower floor.
After completing the segments of floating
floor, the team was able to move on to the
sub-floor section, which consisted of 120 feet
at the center of the walkway. in the sub-floor
areas, the crew was able to work much faster.
standing on the sub-floor as they worked,
crew members were able to use 2-ton, high-
rise pallet jacks instead of the crane to move
concrete pieces to the edge of the sub-floor
where a forklift could pick them up.
once an entire walkway slab had been
removed, operators began work on the slab
and pan decking remnant attached to the
angle iron ledge that led around the walk-
way area. During original construction, the
pan deck was tack-welded to the angle iron
on either side at every corrugated section,
making its removal one of the more physi-
cally challenging aspects of the job. operators
used pry-bars to remove the concrete from the
angle iron in order to expose the corrugated
pan decking. After the deck was exposed,
operators manually pried it away from the
angle iron.
DeAndrea’s team repeated these steps in
each of the four walkways. in the end, the crew
completed the job 9 days ahead of schedule,
more than recovering the original 7-day delay.
DeAndrea lived up to the reputation that had
gotten them the job in the first place.
DiA takes its reputation seriously too.
that is why the airport is in the midst of this
4-year expansion of concourse c, to the tune
of $160 million. general contractor pcL chose
csDA member company DeAndrea coring and
sawing to remove 6,000 cubic feet of concrete
because of their proven industry knowledge
and experience. with careful planning and
preparation, DeAndrea was able to handle
the unexpected with ease. in spite of secu-
rity clearance hang-ups, construction delays
and a powerful updraft to contain, DeAndrea
completed the job early and under budget. ■
pallet jacks were used to move the concrete pieces to the edge of the sub-floor where the forklift picked them up.
DeAndrea’s team completed the job under budget and with 9 days to spare.

t he pittsburgh Light rail, called “the t,” is pittsburgh, pennsylvania’s
25-mile light rail system that functions as a subway between
downtown and the suburbs. in 2006, the pittsburgh port Authority
initiated the north shore connector project to extend the city’s Light rail
transit system 1.2 miles. During the 5-year project, crews will tunnel under
the Allegheny river, building an extension to the north shore at a cost of
$438 million. with 3 new stations, the connector will provide transportation
to a projected 4.2 million riders a year. csDA member company Matcon
Diamond, inc. (Matcon) was contracted to cut through 738 linear feet of
36-inch thick concrete near a major highway, to establish a roofline and
drainage system for the new subway.
CSDA contractor cut 738 linear feet through 36-inch concrete walls to keep Pittsburgh’s North Shore Connector subway drained and dry.
Making the Connection
crew members used a succession of saw blades from 42 inches to 78 inches in diameter in order to achieve the 36-inch-deep cuts.
the wall saw was mounted in an upside-down, or inverted, position in order to make the cuts flush with the exterior roof of the subway.

Although a huge investment in time and
money, city officials hope that the completed
north shore connector will help to revital-
ize downtown pittsburgh. the port Authority
chose north shore constructors (nsc), a joint
venture of obayashi corporation and trumbull
corporation, as the general contractor for the
project. extending the t to the north shore
will require extensive concrete sawing and
drilling, and nsc will rely on Matcon for expert
work on these precision jobs throughout the
duration of the project.
At the early stages of the project, Matcon
was called in to do some roadway sawing and
drilling as well as wire sawing. A year later, nsc
contacted Matcon again when they were faced
with creating access for a drainage system
above the subterranean connector. Matcon’s
reputation, familiarity with the project and
ability to coordinate the necessary labor and
tools to start the job in a short period of time
proved to be the right combination to win
another bid with nsc.
the job was to saw 36 inches into the exist-
ing concrete walls above the future subway.
Matcon’s cuts were to make way for the instal-
lation of the subway’s roofing membrane, an
important feature allowing rainwater to drain
away from the subway roof and into city reser-
voirs. the walls that Matcon was cutting into
were constructed by clearing land and pouring
concrete over the earth. Behind the 36-inch-
thick concrete walls lay dirt and rock, as well
as underground structures that needed to
remain intact.
installation of the membrane required
a smooth surface flush with the roof of the
subway. Accommodating the membrane, while
essential, was not Matcon’s only concern. there
were also existing water mains and parking
garage pilings for operators to consider
when making their cuts. Access to the walls
was limited to one side only, and the flush
horizontal cut would be made by successively
larger blades up to 78 inches in diameter.
According to David Matesic of Matcon,
these facts made “the decision to go with
the Diamond products remote Hydrostress
hydraulic wall saw a necessity.”
Matcon ran the Hydrostress hydraulic wall
saw from a trailer-mounted diesel cushion
cut 25/25 power pack. Because the saw was
operators made cuts along a 25-foot track to each of the walls above the future subway’s roofline.

Methods Used: Wall Sawing
remote-controlled, operators could remain a safe distance from the
blades and debris. Matcon used this saw to perform the inverted flush
cut to each of the walls above the future subway’s roofline.
temperatures were below freezing as the crew set up 25-foot track
along the base of the walls. Matcon operators established a safe distance
from the saw and began cutting with a 30-inch K2 Diamond blade. they
repeated the cut with 42-inch, 54-inch, and 66-inch K2 Diamond blades
in succession. the final cut in each section was made with a 78-inch
Diamond products blade.
the team worked along the length of both walls, setting up the
track and switching blades. A safety concern for which they had to be
aware was the possible fatigue or failure of the flush cut bolts when
using the 78-inch blade. Using such a large blade in an inverted posi-
tion created significant stress on the bolts. operators had to replace the
flush cut bolts in the final 20-foot stretch of cutting.
nsc chose Matcon for this portion of the north shore connector
project because of their previous work and proven ability to manage
a tight schedule. their job was to cut the length of two walls above
the future subway’s roof, to make way for proper drainage measures.
the Matcon team used a remote saw and a series of increasingly larger
blades to complete the 738 linear feet of inverted flush cutting into
36 inches of concrete. Despite a bitter pittsburgh winter, operators
completed the job on time and within budget. ■
operators had to look out for flush cut bolt fatigue due to wear caused by using large blades in an inverted position.
Because the saw was remote-controlled, operators were able to remain a safe distance from blades and debris.

in 1950, tacoma, washington was connected to the Kitsap Peninsula by the tacoma narrows Bridge. for 57 years, this four-lane bridge carried commuters both east and west across the narrow waterway. today, the historic bridge is in the final stages of a retrofit to meet current safety requirements and carry travelers in one direction only.
the washington state Department of transportation (wsDot)
wanted to construct a sister bridge over the narrow waterway to separate
traffic and ease congestion on the roadway to and from the peninsula.
washington voters from several counties approved the construction in
1998. the new bridge was to be a landmark project with a center-span
length of 2,800 feet, making it the longest suspension bridge built in
the U.s. since the Verragano narrows Bridge in 1964. tacoma narrows
constructors (tnc), a joint venture between Bechtel corporation and
Kiewit pacific, was named general contractor and construction began in
safety is the key to a washington state bridge retrofit.
Beefing up the Bridge
the westbound bridge was built across the tacoma narrows in 1950, carrying commuters both east and west until the new bridge was completed 2007.

galloping gertie
i nfamous for twisting and swelling with the wind, the first
tacoma narrows Bridge was called “galloping gertie” by locals and
survived for only 4 months.
the tacoma chamber of commerce began campaigning for a bridge
over the tacoma narrows in the mid 1920s, and the washington legislature
set up the washington state toll Bridge Authority to research the chamber’s
request. A preliminary design for the bridge
by clark eldridge was approved and the
bridge authority at a cost of $11 million
and funds were requested from the federal
public works Administration.
Funding was a problem. so when
bridge designer Leon Moisseiff petitioned
the pwA to build a bridge for $8 million,
Moisseff’s design won out. the eldridge
design called for 25-foot-deep girders to
support the bridge. the Moisseff’s bridge
had a slimmer design, including girders
of only 8 feet. At the time, the science of
bridge aerodynamics was in its infancy,
and shorting the girders’ depth probably
seemed a wise move to limit costs.
once built, however, the girders proved
too shallow to keep the roadbed sufficiently
rigid. the bridge was easily moved about by
the winds. even mild winds could cause the
center span to visibly rise and fall several
feet over short intervals. Locals felt as
though they were on a galloping
horse while trying to cross the overpass
and began referring to the bridge as
“galloping gertie.”
on november 7, 1940, a 42-mph wind
caused the bridge to rise and twist in what
is called a “torsional” movement around
the centerline of the road. the midpoint
remained still as the two halves of the
bridge twisted in opposite directions
around it, ultimately destroying galloping
gertie just 4 months after the bridge opened to traffic.
Leonard coatsworth was the only motorist caught on the violently
twisting bridge that day. He lost control of his car, climbed out, and ran
across the buckling concrete 500 yards to safety. tubby, coatsworth’s cocker
spaniel, was lost in the bridge collapse.

Middle: Leonard coatsworth, the only motorist caught on the collapsing bridge, ran 500 yards to safety.
bottom: A 42-mph wind destroyed galloping gertie on november 7, 1940, just 4 months after the bridge had opened.
2003, on what would become an $849 million
project. Four years later, the new span opened
to eastbound traffic.
once the new bridge was complete, retro-
fitting the 1950s span to handle westbound
traffic and meet modern safety specifica-
tions became the wsDot’s top priority. tnc
resurfaced all four lanes of the bridge and
began the 10-month process of upgrading the
bridge’s railing.
the older low-profile guardrail had to be
removed and replaced. the new rail supports
would then be bolted and welded to the steel
beam below the concrete bridge deck. to gain
access to the steel beams, precise openings
had to be cut through the existing concrete
deck. the wsDot specified 9-inch x 12-inch
rectangular openings through the 6.5-inch
concrete deck with no overcuts. tnc contacted
csDA member company penhall company of
tukwila, washington (penhall) to do the job.
tnc had worked with penhall at earlier
stages of the tacoma narrows Bridge project.
penhall had developed a good reputation with
the general contractor, performing quality
work on schedule and in budget. Both of these
factors were important, as well as the fact
that the bridge would remain open to traf-
fic, limiting penhall’s equipment options. tnc
counted on penhall to execute the precision
cutting job in a limited space, while keeping
dust and debris to a minimum on the busy
thoroughfare.
penhall’s first step was to protect its crew
members from the traffic still utilizing the
bridge. they set up concrete road barriers that
penhall operators cut precise openings through the bridge’s existing concrete deck so that the new guardrails could be secured to the underlying steel beams.

were held with steel clips and bolted to the
bridge deck. next they removed the old, low-
profile guardrail and prepared to set up slurry
containment. slurry containment was put into
place on the top side to keep slurry from leak-
ing through the steel grating contained in
the bridge deck. containing slurry below the
deck, however, was challenging. Access was
limited to the bottom side of the bridge deck.
A specially-trained operator scaled the struc-
tural steel below the deck using 100% fall
protection that connected to the steal beams
in order to install the slurry containment.
penhall operators worked with three
chainsaws: the ics 880F4, 12 gpm, hydraulic
concrete chain saw running the Force4
proper disposal. penhall placed wooden covers
over the openings to secure them until the new
guardrails were installed and concrete poured
back into place. this process was repeated at
each section to be cut across the mile-long
expanse, creating 1,326 openings.

for eastbound traffic, and the old bridge is
being upgraded to meet current safety speci-

chose penhall to execute the precision cutting
and removal of 37 tons of concrete from the
58-year-old bridge to install the railing. with
a team of four, penhall cut openings along a
mile of concrete decking, making way for 1,326
guardrail posts. Because of their planning, care-
ful safety measures and communicating with

began cutting the 9-inch x 12-inch rectangular

Heavy steel was encountered in the concrete
bridge deck as well as plate steel encased in
the concrete in some areas. penhall turned to
their ics representative to assist with choosing
a diamond chain spec to perform the cutting.
A sandwich segment chain proved to perform
very well in these conditions.
the crew used vacuums to collect all the
slurry above and below the concrete deck. the

for the first time in its history, the
Concrete Sawing and Drilling
Association will hold its annual
convention in Mexico—Cancun to
be exact—on March 3–8, 2009. An exciting
program with a keynote presentation, technical
and business sessions and roundtables have
all been planned with recreational and social
activities interspersed to round out a very
comprehensive agenda. Afternoons have been
left free so that attendees can have plenty of
time to enjoy the beautiful beach located just
outside both convention hotels as well as all that
Cancun, Mexico and Mayan coast has to offer.
The CSDA Annual Convention always
draws members from around the world
but in 2009, speakers and presenters will
represent many different countries as well.
Technical presentations at this convention
in Mexico will be made by members from
Liechtenstein, Australia, Canada and
the United States to allow attendees the
chance to see just how global the industry is
becoming, and perhaps, how well-traveled
convention participants are as well.

discussions should provide attendees
with everything they will need
to survive and thrive in today’s
sawing and drilling industry. From
managing large international
projects to leadership, technology
and how to succeed with teamwork,
the programs will offer powerful
information to help owners and
employees take their companies
to the next level and beyond.
A PASSPORT TO PROFESSIONALSAt the 2009 CSDA Convention, participants
will interact with other professionals from all
around the globe. Contractors, manufacturers,
distributors and specifiers. This will be the
opportunity for everyone to make connections,
make an impact and make friends. Networking is
perhaps the main reason many join the Concrete

difficulty, have been revised and enhanced over the years and now are
accepted quite well. they are the new “Basic parameters for concrete
Drilling and sawing equipment” and the revised “tolerances and Limits
for construction Drilling and sawing.” the manufacturers of concrete
drilling and sawing machines, in order to unify the parameters and
allow better comparisons of hydraulic machines, drafted the param-
eters document. the tolerances document forms the preconditions for
accuracy and/or limitations to differentiate the advanced capabilities
of the professional cutting contractor.
the project to collect worldwide market data for sawing and drilling
contractors continues even though there is some resistance by members
to share the data or there is a lack of data to be collected. iAcDs has
been able to identify that the total number of contractors worldwide
exceeds 10,000. great strides were made at the May meeting to expand
the number of countries reporting information, and it was hoped that
this effort would gain wider acceptance for its merits and benefits to
the industry in the future.
Delegates also discussed the industry’s need to educate architects,
engineers and government officials about the advantages of concrete
sawing and drilling and its many practical applications. iAcDs is launch-
ing two new projects focused on reaching these specifiers. one will uti-
lize the association website to create links of sawing and drilling job
stories, categorized by job type that will be readily accessed over the

iAcDs also received several presentations on insurance and the
emerging polishing and finishing market. o’Brien presented a summary
of the csDA insurance program in the U.s., and Jan Lemos informed the
delegates about the successful insurance program they have in sweden.
two presentations were made by Antonio Zerolo of Anzeve (Htc dis-
tributor) and Alain Dupont of Husqvarna of the rapidly emerging floor
preparation market. the current market for tools is estimated at euro
200,000 (Us$320,000) worldwide with an annual growth rate of 35%.
plans were made for conducting the 2009 Diamond Award compe-
tition. iAcDs has assumed the administration of the Diamond Award
for concrete sawing and drilling. the german Association, for the past
decade, has organized this event. it has been successfully held in con-
junction with german trade shows, most recently Bauma. iAcDs has
assumed the administration of this award competition which will be
rotated around the world. the 2009 Diamond Award winners will be
announced at a press conference on wednesday, February 4, 2009 at
10:00 AM during the world of concrete. the world of concrete show
managers will actively promote this event on their website and in pro-
motional literature. in addition, they have offered complimentary hotel
rooms for the first, second and third place winners to attend the event
and the show. iAcDs will offer air transportation for the winners.
the first thirteen years of iAcDs have been very productive as well
thanks to the dedication of sawing and drilling professionals from
around the world who have come together to provide a better future for
the sawing and drilling industry. iAcDs will celebrate its 14th anniversary
in early June 2009 in st. petersburg, russia or Dublin, ireland.

Guns at the Workplace–Liability Challenges
t he presence of weapons, specifically, guns at the workplace
creates the potential for personal injury or death to employees
and third parties (e.g., customers, tenants) at the location and
off-site, if the employee works offsite. An employer, therefore, must
become aware of the potential liability challenges. if the weapons are
used, there is potential liability for a wide range of claims:
• Worker’scompensationclaimsiftheinjuredpartyisan
employee;
• Civiltort,personalinjuryorwrongfuldeathliabilityclaimby
the injured party who is an employee (or his/her estate) if the
injured employee is able to avoid the exclusive remedy provi-
sions of worker’s compensation on the grounds that the injury
was due to intentional conduct;
• Employmentdiscriminationclaimiftheinjuredemployeecan
establish that the shooting was due to an intentional act based
upon the employee’s race, sex, religion or other protected
status;
• Civiltort,personalinjuryorwrongfuldeathclaimbyan
injured third party (e.g., customer, tenant) who is shot by the
employee.
this article will address potential employer liability issues and
suggest means to minimize such concerns.
RECENT HIGH COURT RULING ON SECOND AMENDMENT the U.s. supreme court’s recent ruling in District of Columbia v.
Heller does not in any way restrict what measures an employer may
impose to keep weapons out of the workplace. Briefly, the Heller
case simply holds that individuals have a right to possess an opera-
tional (assembled, unlocked) firearm in their home. in so holding, the
supreme court struck down as unconstitutional a District of columbia
law that prohibited residents from keeping a loaded licensed hand-
gun in their homes. the court’s majority made it clear that the rul-
ing did not affect “longstanding prohibitions on the possession of
firearms by felons and the mental ill, or laws forbidding the carrying
of firearms in sensitive places . . . or laws imposing conditions and
qualifications on the commercial sale of arms.” the court’s majority
also stated that the ruling would not call into question the legality
of state law prohibitions on carrying concealed weapons.
the Business of BuSineSS
STATE CONCEALED WEAPONS LAWS Many states allow law-abiding citizens who are mentally competent
and 21 or older, to carry concealed handguns, and employees who previ-
ously had not thought to bring a gun to work may now feel empowered
to do so. employers still retain the right to regulate the workplace and,
consequently, to prohibit employees from bringing guns there. presumably,
few employers would agree to allow concealed weapons at the workplace,
as no employer would sanction the use of the gun at the workplace. in
order to exercise this prohibition, employers should develop written poli-
cies (or modify existing policies based upon state law restrictions) which
address this prohibition.
PARkING LOTS AND VEHICLES Frequently, issues arise as to whether employees can carry guns in the
employee’s vehicle if it is parked at the employer’s premises. A small but
growing number of states have passed laws which prohibit employers from
barring their employees from transporting a gun in their vehicle, even if
the vehicle is parked on the employer’s property. currently, there are eight
states who have laws on their books protecting the rights of employees
who wish to store a firearm in their locked vehicle: Alaska, Florida, georgia,
Kansas, Kentucky, Minnesota, Mississippi and oklahoma. the national rifle
Association has been the driving force behind the passage of these laws,
sometimes referred to as the “parking lot laws.” other states that have
considered such legislation have included: Arizona, tennessee, Alabama,
california, indiana, Louisiana, Missouri, Montana, new Hampshire, south
carolina, texas and Utah.
these laws, however, have been subject to legal chal-
lenges by employers in a couple of states. in 2007,
oklahoma’s law was held unenforceable by a fed-
eral district court on the grounds that the state
law was preempted by the federal occupational
safety and Health Act (osHA). that case,
ConocoPhillips Co. v. Henry, is now on appeal
before the tenth circuit court of Appeals.
in April of this year, two employer orga-
nizations filed suit in federal court
to enjoin enforcement of Florida’s
law, which had been sched-
concrete openings | 3 5www.csDA.org
uled to go into effect July 1, 2008. in support of their claim that
Florida’s new law should be struck down, the plaintiffs have
advanced three arguments: 1) the law interferes with the private
property rights of employers; 2) the law imposes a “permanent
easement” for use by third parties without providing compen-
sation to the affected employer; and 3) the law conflicts with
osHA’s general duty clause. to date, the federal court has yet to
rule on the parties’ complaint.
in those states where employees are authorized to carry a con-
cealed weapon in his/her vehicle when parked on the employer’s
property, employers may be barred from even questioning the
employee about whether there is a firearm stored in his or her
vehicle. even with such laws, an employer can still prohibit employ-
ees from bringing a firearm into the workplace. in those states
which do not have “parking lot laws,” employers should have a
policy in effect that prohibits guns both in the workplace and in
the employee’s vehicle. this prohibition should include a notice to
employees that all vehicles are subject to search when parked on
the employer’s premises.
WORk OFF OF EMPLOyER’S PREMISES Frequently, employees may be required to work off-site, and
they will use their own vehicles or employer supplied vehicles, for
transportation. Because an employer is typically legally liable for an
employee’s acts while working outside of the employer’s workplace
if the employee is “acting within the scope of employment,” the
employer must also address the possibility of employees carrying
concealed guns while visiting customers or in transit. Again, the
law appears to support the employer’s right to restrict employees
from carrying or possessing a gun while they are performing their
work duties on behalf of the employer.
EMPLOyER RIGHT TO SEARCH A linchpin of any policy must be the right to determine whether
weapons have in fact been brought on site. the only effective
means to make this determination is for the employer to establish a
policy enabling it to search employee lockers, desks, vehicles, hand-
bags, purses and other locations where the guns may be found.
there may be restrictions upon such a policy (or creating the policy
itself) which need to be addressed, including:
• State“parkinglotlaws”generallycontainlanguage
expressly prohibiting an employer from searching an
employee’s vehicle, even if it is parked on the employer’s
property;
• Employeehandbooksorexistingpolicieswhichmayhave
given the employees an expectation of privacy
• Adutytobargainwithaunionifthepolicyrepresentsa
change in the terms and conditions of employment;
• Constitutionalprotectionsforpublicsectoremployees
requiring an employer to establish “probable cause”
(i.e., some objective basis) for a need to conduct the search.
in all cases, the searches should be conducted in a reasonable
manner (e.g., without accusatory or other behavior which will
humiliate or embarrass the employee; without destruction of employee
property, if possible; without disclosure of other employee property which
is properly confidential) by individuals who are trained to document and
preserve evidence. searches which are done in an unreasonable manner
can create potential liability to the employer for defamation or intentional
infliction of intentional distress.
WRITTEN POLICy As indicated, there must be a written policy, communicated to all
employees, which should (subject to state law requirements of specific
provisions):
• Asserttheemployer’slegitimatebusinessreasonforprohibitingguns
(i.e., to maintain a safe and healthful workplace and to eliminate the
potential for workplace violence);
• Definewhatismeantby“weapons”or“guns”;
• Identifytheemployer’spremisesandotherlocations(includingpark-
ing lots and off-site work locations) where guns are prohibited;
• Requireemployeestoreportanyevidencewhichindicatesthat
weapons or guns have been brought on to the premises (while stat-
ing that such reports will be kept as confidential as possible and that
no employee will suffer retaliation for making such a report);
• Clearlystatetheemployer’srightandintenttoconductrandom
searches of the workplace and vehicles to determine whether guns
have been brought to the workplace (within the restrictions of exist-
ing state laws, handbooks, policies or labor agreements which can-
not be eliminated);
• Includeconductingemployeetrainingonthepolicyandproviding
copy of the policy to each employee;
• Requireemployeestosignawrittenacknowledgementof

• Allowforrandomorothersearchesandenforcementofthepolicy
with consistent discipline, based upon a fact-specific inquiry into
each offense.
CONCLUSIONBecause of recent tragic workplace shootings, employers are being
called to account for weapons brought on site. At the same time, many state
legislatures are endorsing the rights of citizens to carry concealed weapons.
employers must commit themselves to protecting employees and others
at the workplace from this hazard, while recognizing potential employee
state law rights. if an employer carefully documents its efforts, and an
unfortunate accident occurs, these actions should reduce or eliminate its
potential liabilities.

The World of Surface Preparation
Advancements in the machines, acces-
sories and techniques involved with
surface prep have recently sparked
a strong interest amongst many sawing and
drilling contractors to explore expansion into
the surface prep markets, to complement tra-
ditional sawing and drilling services. often,
concrete slabs can be rejuvenated or repaired
at a fraction of the cost of demolition and
replacement. the concrete slab surface can
be changed to look different, allow for ar-
tistic expression and uniqueness, to provide
more light, to be easier and less expensive to
maintain and to provide better bonding sites
for new performance coatings.
the concrete slab surface can be modi-
fied or repaired, rather than replaced due to
the slabs containing some of the damages
or defects that are typically associated with
concrete slabs, including blistering, cracking,
crazing, curling, delaminating, discoloration,
dusting, high/low spots, pop-outs, scaling, spal-
ling, micro fractures, heaving and/or shifting,
surface traction and high vapor transmission.
it is important to understand more about sur-
face prep, as it is quickly becoming an integral
part of our industry.
surface prep is an industry-accepted term
for equipment used in the mechanical prepara-
tion of concrete slab surfaces. the key to this
definition is that a mechanical preparation of
the slab surface and does not include chemical
acids, phosphates, degreasers, poultice and/
or pressure washing. Many folks lump it all
together, but the reality is that the use of our
restricted definition helps to carve out of the
larger picture the machines and accessories
that better parallel the current sawing and
drilling equipment used in our industry.
surface prep can be
classified in three cat-
egories: stock removal,
coating removal and
coating preparation.
stock removal is
simply removing mate-
rial to lower the slab
height, removing loose
delaminating concrete,
smoothing trip hazards
(discontinuities), remov-
ing portions of the slab
that are defective (dam-
aged or out of spec), or
removing material to
provide drainage, an
artistic look or increased
traction.
coating removal is
removing an existing
coating from the slab.
the coatings can be topical like paint, epoxy,
urethane, elastomeric/waterproof membranes,
and waxes; or synergistic coatings like chemi-
cal/petroleum/organic stains, acid stains, dyes,
curing agents, admixtures, sealers, and densi-
fiers. other caps or coverings include polymer-
modified cements, overlays, tile, carpet, etc.
coating preparation is creating an ideal
surface profile for a particular coating to
increase the bond strength and integrity. the
bond of the new coating to the existing slab
surface can be maximized by providing the
best ‘bite’ for the coating to adhere to the
slab. the profile of the slab surface is typically
categorized by the concrete surface profile
(csp) numbering system that was developed by
the international concrete repair institute.
the csp system uses a csp range of 1
through 9 to define the surface profile.
grinding is usually in the csp 1-2 range, plan-
ing is usually in the csp 3-9 range depending
on the cutters and spacing between the cut-
ters, and scabbling is usually in the csp 7-8
range. the coatings might call for a specific
csp number; whereas sealers having an appli-
cation thickness of up to 3 mils might call for
a csp in the 1-2 range. thin mil coatings (4-10
mils) might call for a csp in the 3-4 range; high
build coatings (10-40 mils) might call for a csp
in the 2-5 range; self leveling coatings (circa 50
mils) might call for csp in the 3-6 range; and
polymer overlays (0.125 to 0.250 inches thick)
might call for a csp in the 4-9 range.
A typical job may include multiple catego-
ries such as removing a coating and providing
3 6 | septeMBer.08
a profile for a new coating. it is important to
understand each phase of the job to choose
the best machines, accessories and techniques
to accomplish the goals of that phase. the
phase of the job for removing a coating might
involve entirely different equipment than the
phase for profiling the surface.
the machine, accessory and the technique
are sometimes lumped together. For example,
someone might view a concrete grinder as
simply a concrete grinder and not fully appre-
ciate the multitude of different grinders on
the market, including planetary and rotary
grinders. there are major differences in power
and weight, various tooling speeds defined by
the disc diameter and rpMs, different grind-
ing head pressures, a multitude of different
accessories including abrasive stones, scarifer
wheels, carbide scrapers, polycrystalline dia-
mond (pcD) and diamonds in a multitude of
grits and bond types. to truly appreciate the
advances to the state of the art in the sur-
face prep industry, one must be able to under-
stand that the machines on the market today
typically have a cadre of different accessories
designed for specific purposes. the techniques
used also play a vital role in the overall produc-
tion rates of a given job.
surface prep equipment can be grouped
into five different classifications based on
the methodology of the cutting action of the
machine: grinders and/or polishers (horizontal
rotary abrasive, shredding or slicing action);
planers (aka scarifiers, milling or flailing
action); shot blasters, needle scalers and scab-
blers (hammering and/or impact action); chisel
scalers and strippers (scrapping action); and
saws, crack chasers and decorative saws (verti-
cal slot grinding aka cutting action).
grinders and polishers are very similar.
they work in a horizontal plane to level, pro-
file, clean and/or polish a surface. polishing
and grinding is abrading the surface using
friction, typically with accessories that are
abrasive.
there are two distinct categories of grind-
ers/polishers based on the motion of the discs
and accessories, which are planetary and
rotary. the planetary machines have smaller
planets of accessories that independently
rotate (passively or actively) around a larger
‘solar system.’ the rotary machines the disc
speed is typically constant and in a circular
motion. each disc maintains some resil-
iency to follow the slab contours that
will keep the working width to the
width of each disc. some overlap,
some are designed to move
in a sweeping motion.
the advantages and
disadvantages of the
planetary machines
are that it creates a
random scratch pat-
tern, has varied dia-
mond speeds as it rotates and a larger working
width of the machine which is across the ‘solar
system’ and not the individual planets.
the grinding action of a grinder and
polisher is a horizontal motion and in many
ways is similar to the grinding action of a
concrete saw that is vertical. grinders and
polishers are in many ways very similar to
concrete saws. the bond hardness, the diamond
concentration and the size of the diamonds all
play a critical role in the life and production
rate of the grinding action. concrete saws are
really grinders that are grinding a vertical slot
in the slab surface. the knowledge we have
gained working with diamond blades can help
us better understand the diamond accessories
on grinders.
polishing is done either wet or dry and
involves a progression of increasingly larger
diamond grit sizes in the accessories. the acces-
sories are typically classified as ‘metals’ (vac-
uum brazed diamonds, metal bonds, sintered
bonds, etc.), and ‘resins’ (semi-metal hybrids,
phynolic resins and polymer bonds, etc.).
typically the polishing process includes the
application of a densifier to harden the slab
CsdA issues Polishing ConCrete sPeCifiCAtion
The Concrete Sawing & Drilling Association (CSDA) has been the leading associa-
tion for issuing standards, specifications and best practices for the sawing and drilling
industry since its founding in 1972. CSDA provides vital materials for architects and
engineers to work on a professional basis with sawing and drilling contractors. As
part of its effort to achieve these goals, CSDA has developed a Specification entitled
Polishing Concrete.
Establishing proper industry standards ensures that each professional following the
CSDA Specifications is providing the highest levels of safety and workmanship. CSDA
Specification CSDA-PC-113, Polishing Concrete, covers the proper codes and standards
to be applied on polishing projects, as well as the needed prerequisites for the work,
polishing setup procedures and equipment operation.
“It pays for architects, engineers and cutting contractors to be working with the
same up-to-date industry standards in today’s competitive construction market. More
than ever before, a contractor’s success depends on access to the most current meth-
ods and technology to get a job done and to do it right.”–Patrick O’brien, Executive
Director, Concrete Sawing & Drilling Association.

skin, prevents dusting, and increases the shine.
polished concrete floors are easy to maintain,
have long life, have increased reflectivity of
available light, and allow the slab to breath if
vapor transmission is high. typical progression
formula is: 100g, 200g, 400g, 800g, 1200g
and 3000g. some technicians double up and
some step back a grit on the transition from
metal to resin.
planers are also known as scarifiers, mill-
ing machines, rotary cutters/grinders and sur-
face prep machines. planers spin a cylindrical
drum tangent to the slab surface removing the
top surface at a controlled depth with either
rigid abrasive cutters milling the top surface,
or, with smaller carbide or steel cutters on
independent shafts on the drum perimeter by
a flailing action of the smaller cutters as the
drum rotates. they can be classified as either
an upcut or downcut machine depending on
the drum rotation with respect to the motion
of the machine. some of the planers use dia-
mond blades and can remove large depths of
material in a single pass.
shot blasting uses a machine that propels
thousands of particles per second at the slab
surface, then the particles are circulated back
into the machine whereby the dust, debris
and worn particles are vacuumed away and
the process is repeated.
needle scalers and scabblers use com-
pressed air to propel a piston perpendicular
to the slab surface to drive hardened steel rods
or carbide tipped bits (respectively) into the
slab surface with a hammering action.
A chisel scaler uses compressed air to pro-
pel a piston to drive metallic blades with a
hammering action. strippers are typically
electric powered with a slicing or chipping
action, but both are used to remove things
like tiles, carpet and Vtc. A sharp blade can
sometimes scrape the slab surface clean of
glues and adhesives. Larger self-propelled die-
sel, gasoline, propane, electric and battery
powered strippers are available that scrape
the floor clean of tiles, carpet and Vtc with
weight and power.
concrete saws are also part of the surface
prep machines for stock removal. the depth of
cut can be fixed to allow for a series of cuts in
a slab close enough together to chip down to
a specific level (at the root of the cuts) to allow
for a slab to be lowered or recapped.
crack chasers and decorative (deco) saws
are highly maneuverable slab saws used to fol-
low random cracks for repair or create artistic
cuts in a slab surface for aesthetics. typically
these saws use thicker blades in bevel or stan-
dard configuration.
typically the machines used in surface prep
can be used in a wide range of jobs. the trick is
to understand that some machines, accessories
and techniques will be much more productive
in specific niche applications. the contractor
can perform a cost analysis on the job based on
the cost of the machine, accessories and labor
and determine a cost effective approach using
what some would consider practical solutions
of using multiple machine types and/or multiple
accessories to complete the job. to fully under-
stand the best solution, one should consider
mixing (pairing) methodologies of either the
accessories or machines.
Example 1: removing stock with scarifier then
grinding the slab smooth with a grinder.
Example 2: Using pcDs to remove a resilient
coating then using diamond grinding accesso-
ries to create the desired csp and clean the slab
surface of coating residuals to provide a clean
open bonding surface for the new coating.
Example 3: Using a grinder to feather out the
zebra stripping after shot blasting.
the advancements in the machines, acces-
sories and techniques in surface prep are pro-
viding the csDA contractors with new market
opportunities. the world of surface prep can be
broken down simply into three categories (stock
removal, coating removal and coating prep)
with five different classifications of machines
based on the methodology of the cutting action
(grinders and/or polishers; planers; shot blasters,
needle scalers and scabblers; chisel scalers and
strippers; and saws). recently the csDA stan-
dards and specifications committee released a
specification on polishing concrete. the csDA
involvement in the creation of this specifica-
tion demonstrates a commitment to developing
industry accepted definition of a true polished
concrete slab without major shortcuts to the
claim of a polished slab.

A Safe Workplace is a Drug-Free Workplace
t he majority of individuals who abuse alcohol and other drugs are
employed, creating significant but avoidable safety and health
hazards in the nation’s workplaces.
small businesses in particular have big disadvantages when it comes
to substance abuse. Because they are less likely than larger companies to
have programs in place to combat it, they may be more likely to employ
drug users—and the cost of just one accident caused by an impaired
employee can devastate a small business.
the good news is that small business owners can protect their
companies and help reduce substance abuse in their communities by
implementing workplace prevention programs that educate employees
about its dangers and encouraging individuals with related problems
to seek help.
Although not required by the occupational safety and Health
Administration (osHA), drug-free workplace programs are natural
complements to other initiatives that help ensure safe and healthy
workplaces and add value to America’s businesses and communities.
such programs help reduce occupational injuries and illnesses and send
a clear signal that employers care about their employees.
A comprehensive drug-free workplace program generally includes
five components: a written policy, supervisor training, employee educa-
tion, employee assistance and drug testing. Although employers may
choose not to include all five, it is recommended that all be explored
when developing a program.
WRITTEN POLICyA written policy is the foundation of a drug-free workplace. every
organization’s policy should be tailored to meet its specific needs;
however, all effective policies have some aspects in common, including
why the policy is being implemented, a clear description of prohibited
behaviors, and an explanation of the consequences for violating the
policy. sharing all policies with all employees is essential for success;
therefore, employers should be certain that all employees are aware of
their drug-free workplace policy and program.
SUPERVISOR TRAININGAfter developing a policy, an organization should train those indi-
viduals closest to its workforce—supervisors. training should ensure
that supervisors understand the drug-free workplace policy, ways to
recognize and deal with employees who have performance problems
that may be related to substance abuse and how to refer employees to
available assistance or for drug testing as appropriate.
supervisors’ responsibilities should include monitoring performance,
staying alert to and documenting performance problems and enforcing
the policy. supervisors should not, however, be expected to diagnose
substance abuse problems or provide counseling to employees who
may have them. if supervisors are responsible for making referrals for
drug testing based on reasonable suspicion, they also must be specifi-
cally trained on how to make that determination.
EMPLOyEE EDUCATIONA drug and alcohol education program provides employees with
information they need to cooperate with and benefit from a drug-
free workplace program. effective programs provide company-specific
information, such as the details of the company’s policy, as well as
general information about the nature of addiction; its impact on work
performance, health and personal life; and help available for related
problems. All employees should participate, and the message should
be delivered on an ongoing basis through a variety of means, such as
home mailings, displays, brown-bag lunches, guest speakers and sessions
at new employee orientation.
4 0 | septeMBer.08
EMPLOyEE ASSISTANCEA critical component of a drug-free work-
place is providing assistance to employees who
have problems with alcohol and other drugs.
employee Assistance programs (eAps) are work
site programs that provide problem identifi-
cation, assessment and referral services for
employees. they are effective vehicles for
addressing poor performance that may stem
from an employee’s personal problems, includ-
ing substance abuse.
eAps benefit employees and clearly dem-
onstrate employers’ respect for their staff.
they also offer an alternative to dismissal
and minimize employers’ legal vulnerability
by demonstrating efforts to support employ-
ees. in addition to counseling and referrals,
many eAps offer services such as supervisor
training and employee education.
At a minimum, businesses should main-
tain a resource file from which employees
can access information about community-
based resources, treatment programs and
help lines.
DRUG TESTINGsome employers decide to drug test for
a variety of reasons, such as deterring and
detecting drug use, as well as providing con-
crete evidence for intervention, referral to
treatment and/or disciplinary action. Before
deciding to test, employers must consider cer-
tain factors, such as who will be tested, which
drugs will be tested for and when and how
tests will be conducted. they must also be
familiar with any state and Federal laws (such
as the Department of transportation’s drug-
and alcohol-testing regulations for employees
in safety-sensitive positions) or collective bar-
gaining agreements that may impact when,
where and how testing is performed. it is
strongly recommended that legal counsel be
sought before starting a testing program.
DRUG-FREE WORkPLACE RESOURCESthe Department of Labor’s working
partners for an Alcohol- and Drug-Free
workplace program and osHA encourage
small businesses to maintain safe, healthy and
drug-free workplaces and offer a number of
online tools to help them do so.
the working partners web site (www.dol.
gov/workingpartners) is a central source of
information about workplace drug and alco-
hol issues and strategies for addressing them.
For example, businesses needing to develop a
drug-free workplace policy from scratch can
use the site’s Drug-Free workplace Advisor
program Builder, which will guide them
through the different elements of a com-
prehensive policy and then generate a policy
statement based on their selections.
Another site feature, the substance Abuse
information Database (sAiD), is an online
repository of hundreds of documents related
to workplace alcohol and drug abuse, includ-
ing sample policies, surveys reports, training
and educational materials, and legal and regu-
latory information.
the site also has information about related
state laws, community-based organizations that
may assist businesses in becoming drug free
and help lines that can assist individuals who
have alcohol or drug problems. presentations,
fact sheets and articles that can be used for
supervisor training and employee education
purposes also are available.
Elena Carr is Drug Policy Coordinator and Director of the Working Partners for an Alcohol- and Drug-Free Workplace program in DOL’s Office of the Assistant Secretary for Policy.
Dr. Don Wright is the Director of OSHA’s Office of Occupational Medicine.
OSHA and NFIB recently formed an Alliance to enhance safety and health throughout the nation’s small and independent businesses. As part of this Alliance, they will work together to communicate with small businesses about how they can protect their workplaces from the hazards of alcohol and drug abuse.

w hy should i care about losses? i have insurance. Heck, i pay
all that money in premiums and my insurance representa-
tive tells me that i need to control losses. But since i have
insurance, what’s wrong with submitting claims? And why do i have to
worry about controlling costs? isn’t that the problem of my insurance
company? Have you had this conversation with yourself, your partner
or partners or your insurance agent recently? More often than you care
to think about?
over the last twenty plus years, i have
been asked this question, in one form or
another, many times. And i have had time
to think about the answer. And the answer
might help readers in two ways. First of
all, if your company is a member of the
csDA insurance program, the answer can
help you realize what benefits you are
accruing by being a member. second, if
you are not a member, the answer might
help you understand the advantages of
such a program.
when you think about your insurance
costs, it only seems fair that if you entered
into a contractual arrangement (your pol-
icy) with an insurance carrier to cover your losses, then you should not
have to deal with controlling these costs. why should you have to be
concerned with your costs?
the typical insurance arrangement (the standard commercial mar-
ket) is one in which you give money to an insurance company for
coverage of specific perils or accidents. your insurance company then
takes your premium and tries to protect itself by making sure that only
those perils covered by your policy are covered. their incentive is that
if they are successful, if they have money left over, it will revert back
to them to keep.
while the csDA insurance program offers policies that are much
broader than those found on the standard market, the process for
going about securing coverage and then in administering your policy
is almost the same as securing coverage in the open market. with one
big exception. Money left over in the csDA insurance program can be
used to reward those with few losses with lower insurance premiums
going forward or to be returned as dividends.
while this may sound good, there are still other benefits. companies
that do not have losses are able to avoid many of the hidden costs
By Bill Crimmins
Why Should I Care About Losses?
insurAnCe Corner
associated with loss. Hidden costs such as increased paperwork, broken
machinery, accident investigations, employee turnover, lost jobs due to
higher insurance costs, all play a role in loss prevention. the benefits of
controlling loss are not as easy to see as compared to a balance sheet.
However, think about how your balance sheet would look if you were
able to get those jobs that were lost due to a high workers’ compensa-
tion modifier. you could be looking at substantial increases in profit.
oK, so you’re still skeptical. Let’s look at
a possible claim scenario. A ten-year veteran
employee is working at a site and decides
to pick up a saw resulting in a lower back
strain. the injury puts the employee out of
work for weeks. As a business owner, you
have contractual obligations to complete
your work in a professional manner. As a
result you must continue the job. However,
now you are one person short and need to
find a replacement while the injured worker
recuperates. immediately your company has
an uninsurable loss. what is the uninsurable
loss? well, for the last ten years, you have
invested in the skills of that employee. now
that you do not have a skilled worker on
the job, you begin to lose money on that investment. the uninsured
loss comes in the form of lost productivity. if the employee did not get
injured on the job, the project would have been completed on time.
there are many different scenarios that could be used to demon-
strate the need to manage risk and prevent losses. these losses come
in the form of lower or lost productivity, lower or lost profitability, low
morale, excessive turnover or staff burnout. the point is that preventing
loss or controlling loss that does occur is still one of the best methods in
managing risk. so, yes, every company, no matter what kind of or how
much insurance they purchase, must be concerned with claims and the
losses that accompany them.
the csDA insurance program is available to help with your risk man-
agement. proper coverage, claims management and loss prevention are
just a few of the services offered to members of the program. it may be
in your best interest to contact the csDA insurance program.

Hilti Introduces New CombihammerWith a new 1700 watt motor, the
Hilti TE 80 ATC-AVR is a very powerful
combihammer. The TE 80 ATC-AVR makes
light work of a wide range of demanding jobs
including hammer drilling in the ¾-inch to
6-inch diameter range in concrete, masonry
and natural stone, drilling through-holes
up to 6 inches in diameter in concrete and
masonry, and heavy chiseling work and
drilling with high torque in wood and steel.
The active vibration reduction feature
provides optimum operator protection and
a high level of working comfort even during
long periods of use. A mass damper system
suspended on springs inside the casing
absorbs vibration in the tool’s longitudinal
axis while the grip, which is decoupled from
the rest of the tool, efficiently absorbs even
vibrational torque. Another safety feature is
an active torque control, an electronic rapid
cut-out system that disengages the tool drive
system if the drill bit sticks and the tool
starts to rotate too quickly, thereby providing
additional operator protection. For more

why i joined CsdAto me, the wealth of knowledge available from other members
within CSDA has been the most valuable benefit of joining the
association.
I got into this business from the vendor’s side of things, working with a
manufacturing company. I knew then that CSDA was the place to go to
make connections in the sawing and drilling industry. So when I started
my business in 2000, becoming a member of CSDA had already been
decided. It was just a matter of establishing my company first. One year
after setting up shop, I joined. Since then, I’ve enjoyed the friendships,
information and programs made available to me through CSDA.
The most important benefit of membership for my company has been
attending CSDA functions. At the conventions and meetings, you can
sit down and talk to professionals from every corner of the industry in
a relaxed and social environment. You can find out about new types of
equipment, how to modify the equipment you have, learn a different
approach to a particular type of job, or get tips on managing employees.
Sometimes, you’ll even be the one giving advice.

Help Shape the Future
of Your Industry
Email future@csda.org
m y involvement with csDA and the sawing
and drilling industry dates to 1982, when
i joined ge superabrasives, formerly the
specialty Materials Department. the industry has
undergone dramatic change since that time, especially in
the last decade. csDA has also changed. At its formation
in 1972, csDA started with 13 members and a budget of
$13,000. today, we have 550 members and our budget
exceeds $1 million.
the numbers reveal a growing and thriving
association. csDA has developed a broad array of
highly successful safety and training programs. we
provide manuals, handbooks and DVDs, as well as
seven classroom/hands-on programs to help operators
maintain the highest level of skill and professionalism.
csDA has embraced technological advances, establishing
the industry’s professionalism worldwide via the internet
and offering 17 online courses for sawing and drilling
professionals.
consider for a moment how these programs and
others came to fruition. they are the products of your
ideas and questions.
too often individuals don’t realize their importance
to our association or industry. csDA is an association
of sawing and drilling professionals. the csDA Board,
officers and staff listen to input from members and
prospects, and they take action accordingly. this process
of listening and taking action has resulted in the
exceptional growth and world-class benefit programs
that have established csDA as an authority in our
industry throughout its 36-year history.
today’s operators require specialized training to
use their hi-tech equipment, and contractors are relying
on email and the internet more than ever to run their
businesses. tomorrow’s csDA and the sawing and
drilling industry will undoubtedly see further changes
in technology and business practices, creating a new
generation of professionals with different needs.
it is incumbent on today’s leaders to provide this
next generation with the tools necessary to maxi-
mize the industry’s growth and professionalism in
the future. we must proactively plan ahead to ensure
csDA and the sawing and drilling industry will con-
tinue to thrive.
Because the thoughts and comments of individuals
like you have shaped the programs of csDA into the
successful benefits we offer today, we now turn to
you again to help guide our future. whether you are
a member of csDA or a reader of Concrete Openings,
email future@csda.org to share your thoughts on the
sawing and drilling industry and csDA of the future.
what will it take for our association and our industry
to prosper for years to come?
the results from your emails to future@csda.org
will be summarized and reported in a subsequent issue
of Concrete Openings. thanks for your help.

Husqvarna’s new WS 440 HF is setting a new standard for electric high cycle wall saws. The saw is based on a totally new technology, which gives the saw increased power for fast and efficient sawing. The powerful, water-cooled electric motor generates 17 horsepower to the shaft, despite the fact that the saw only weighs 55 pounds. The 9,000 rpm permanent magnitized motor delivers 100% power to the blade while cutting concrete or steel.
Husqvarna has succeeded in optimizing the weight/power relationship and developed a saw that is light and flexible but also powerful!
The NEW WS 440 HF Wall Saw.
