t he concrete sawing & Drilling Association (csDA), in pursuit of

excellence for all of its contractor members, officially launched

its newest program of excellence, the company certification

program, in March of this year. Many customers today are requiring

subcontractors to go through a pre-qualification process before they

invite them to submit proposals or allow them to work on their projects.

this program will help csDA members quantify their qualifications for

doing the work that their customers specify.

this pre-qualification requirement is driven by several factors. First,

the customer desires to manage their risk by insuring that subcontractors

meet a baseline standard. second, the project owner or insurance carrier

requires the subcontractor to meet a baseline standard to work at certain

facilities or on certain projects. third, the contractor needs to determine

the best subcontractor to use on their projects and avoid needless problems

on these projects. the csDA company certification program includes many

elements in its three levels that will assist the subcontractor in this pre-

qualification process.

the Level 1 certification has been devised to determine if a company

meets the stringent requirements set forth by csDA. By attaining

Level 1, these companies have demonstrated a strong commitment to

professionalism in management and business practices.

companies that achieve Level 2 certification have shown that they

follow generally-accepted business practices based on the internationally

recognized iso process. Level 2 companies have implemented effective

business systems to operate more effectively on a daily basis which can lead

to cost savings and improved customer satisfaction. Level 2 companies will

meet the requirements for most heavy industrial projects.

companies that achieve a Level 3 certification are fully compliant to

iso9000 requirements. to achieve Level 3 certification, a company must pass

a rigorous onsite audit of its quality management system that is comparable

to an iso9000 certification audit.

i invite you to undertake this process, if, for no other reason, than to

identify those areas in your own organization where you excel. You can

stress certification to your clients when you promote your company in

various marketplaces. in addition, the process helps highlight those weaker

areas within your organization that can be improved. this information is

vital to properly manage sawing and drilling companies. Visit the csDA

website today at www.csda.org to learn more about the company

certification program.

We understand what contractors like George Cramer go through every day. So every day, we push ourselves to perfect our tools and technology to makea rough, dirty job a little easier and you even more effective.

concrete cutting the 14,572-foot-long Bay runway at JFK Airport.

Why would you invest in anything less?

30 Years of Innovation


t he concrete sawing and Drilling association formally launched its newest Program of excellence, the company certification Program, at its recent

annual convention. the 3-tier program was developed by the csDa certification committee for cutting contractors to provide owners, architects, engineers, general contractors and government officials with a valuable pre-qualification tool and to enhance the level of professionalism possessed by concrete sawing and drilling contractors. the new company certification Program is the first of its kind in the industry.

in addition, it was announced that csDA member cutting edge

services corp. of Batavia, ohio, became the first contractor to be certified

at Level 1 of the program.

level 1 certification was developed to demonstrate that a company

meets the stringent financial, operational and safety requirements of

the industry to do business as a professional sawing and drilling contrac-

tor. to achieve Level 1, companies must successfully pass a written review.

“i am extremely pleased to have my company be the first to achieve Level

1 status,” said tim Beckman, owner of

cutting edge services corp. “the csDA

company certification program provides

me with documentation that can i pres-

ent to customers and general contractors.

i can prove that the company not only

performs safe and efficient cutting work,

but also uses sound business practices.”

level 2 includes heavy industrial

prequalification. to attain Level 2, a

company must prove that they have

implemented sound business practices.

the Level 2 certification covers all the

requirements of the Level 1 certification

plus an assessment of each of the fol-

lowing processes: subcontractor control,

maintenance, planning, sales, training,

purchasing, design, calibration, measure-

ment systems, continuous improvement

and management system review. in addition, the company must have

procedures in place for these processes to ensure consistent practices.

to achieve Level 2 certification, companies must successfully pass a writ-

ten review.

level 3 will provide potential customers with proof that a company

has an effective total Quality Management system in place. to achieve

csda launches company certification ProgramCutting Edge Services of Batavia, Ohio—the First Company to be Certified

Level 3 certification, the company must have successfully implemented

all the requirements of a Level 1 and Level 2 certification plus have

effectively implemented a best practice for records control, corrective

and preventive action and internal auditing that assesses the effective-

ness of the company’s quality management system. to achieve Level 3

certification, a company must pass a rigorous on site audit of its qual-

ity management system that is comparable to an iso9000 certification

audit. A company that has achieved Level 3 certification has met the

highest standards set by csDA and is fully compli-

ant to the iso9000 international quality standard.

For more than 10 years, csDA has had a

certification process in place for individual sawing

and drilling operators. operators are certified in

cutting disciplines of slab sawing, core drilling,

wall and hand sawing and wire sawing. this new

certification program extends the reach of the

certification process from the individual operator

to the entire company.

the company certification program is being

administered by a third party auditor, Asurency, inc.,

to maintain complete confidentiality of all records.

Asurency, inc. has more than 15 years experience

in conducting certification audits and business and

iso implementation counseling. Asurency, inc. is

experienced in several market segments including

construction, light and heavy industrial, high-tech

and the service industry.

the csDA company certification program is available to all sawing

and drilling contractors. For more information, visit www.csda.org and

skycity rooftop pool removal project.



a development plan for a luxury hotel and casino

in auckland, new Zealand, consisted of extra

floors that include four VIP villas with gaming

areas and VIP salons. In order to add these extra floors, a

rooftop swimming pool needed to be removed.

skycity is one of Auckland’s biggest hotels, with over 340 rooms

and views of the city’s harbor. one of the main draws of the hotel is

the sky tower, a 328-meter-tall (1,076-foot) building that is the largest

man-made structure in new Zealand. Visitors can dine in one of the

tower’s restaurants or perform a 192-meter (630-foot) wire jump from

the tower’s viewing platform. the Vip area development project was

scheduled for completion in June 2011. this is so that the hotel will be

prepared for a large volume of high-profile visitors arriving in september

for the 2011 rugby world cup, an international tournament that

features 20 teams and runs for two months.

the removal of the rooftop pool was scheduled for three weeks

in February, and had to be done quickly to keep the project on track

while keeping disruption of hotel operations to a minimum. the pool

measured 13.3 meters (43.6 feet) long, 5.1 meters (16.7 feet) wide and

had a depth ranging from 1.2 meters (3.9 feet) to 1.8 meters (5.9 feet).

the concrete walls and floor of the pool were 250 millimeters (9.8 inches)

thick. the general contractor for the project, Hyline construction Ltd.

of Auckland, began searching for a contractor that could take out the

concrete pool without causing large amounts of vibration and noise

that would disturb hotel guests.

A1 Kiwi cutters & Drillers Ltd., a csDA member based in Auckland,

was contracted by Hyline to remove the pool. the plan devised by A1

Kiwi cutters and approved by Hyline, called for the walls of the pool

to be cut into 16 sections using a wall saw with diamond blades. it

was specified that none of the cut sections could weigh more than 2.7

tons due to capacity of the crane on site. each cut section would have

two 132-millimeter-diameter (5.2-inch) holes core drilled into it so that

lifting straps could be attached, then the section could be removed by

the crane. Before the final cut was made on each section, the piece

would be rigged for removal. the floor of the pool was to be cut into

14 sections using a floor saw, and a similar method was used to hold

the weight of the cut piece before the final cut and removal. A1 Kiwi

cutters was responsible for the provision of machinery, labor and slurry

control during all the cutting and drilling processes.

As the hotel was to remain fully operational during the work, wall

sawing and diamond core drilling was the best choice. wall sawing

is much more quiet and efficient than demolition methods like

jackhammering or the use of a wrecking ball. “this technique meant

minimal disruption for the hotel staff and guests, as there would be less

vibration, less debris and the cutting would not be as labor-intensive as

breaking or wrecking,” said penny simons, co-owner of A1 Kiwi cutters

& Drillers Ltd.

the cutting contractor worked closely with Hilti new Zealand Ltd.

and used a Ds ts20-e wall saw to perform the majority of the cuts. the

first step was to wall saw the internal perimeter where the pool walls

met the pool floor. the cuts were made 50 millimeters (2 inches) above

the joint and were completed in five hours. it was then time to core drill

the 132-millimeter-diameter (5.2-inch) holes for the lifting straps. two

holes were cored per section using a Hilti DD200 core drill. the final part

of the pool job involved vertical wall sawing. the walls were divided into

16 pieces and measured to be no longer than 2.4 meters (7.9 feet) and

weigh no more than 2.7 tons. the sections were rigged while the final

cut was being made, then the piece was removed from the work area.

the process was repeated until all 16 sections had been cut free. this

took six days to complete.

once all of the concrete pool wall sections were removed from the

work area, the cutting team began to mark out the floor of the pool for

cutting and core drilled holes measuring 132 millimeters (5.2 inches) in

diameter to attach lifting straps. An operator then used the floor saw to

splash at SkyCityRooftop Pool Removal Aids Auckland Hotel Renovation

the Auckland skyline.

making a

cut the pool floor into 14 sections, again ensuring that each section was

no heavier than 2.6 tons. As with the pool wall sections, each cut floor

section was rigged by crane before making the final cut and removing

the piece from the work area. the cutting of the pool floor concrete

took 10 days.

During the entire cutting work, slurry was collected via wet vacs and

stored in sealed containers. when filled, these containers were lowered

by crane and then emptied by environmental contractors who disposed

of the slurry according to current legislation.

control of the slurry and waste water was

critical, as A1 Kiwi cutters had to make sure

that no waste leaked into the occupied hotel

rooms on the floor below.

Due to the strict time frame applied to the

whole project, time was of the essence. the

hotel stood to lose a large amount of revenue

if the new facilities were not available for the

rugby world cup. in order to complete the

job, A1 Kiwi cutters had up to five operators

on site most days. Mark simons, director of

A1 Kiwi cutters & Drillers Ltd, oversaw the

day-to-day management and organization

of the team. simons operated the wall saw

while operators took care of the core drilling,

floor sawing and slurry control. the pool was

successfully removed in 16 days.

the main safety concern was the risk of

pool sections falling before being removed.

this concern was overcome by the core drilling

of lifting holes and rigging the section to the crane prior to each

final cut. Another safety concern was the weather. the work was

completed during the summer months and operators were exposed

to the sun for long periods of time while working on the rooftop.

the contractor made sure that all operators used sunscreen, stopped

regularly for breaks and kept hydrated. All operators wore standard

personal protective equipment like steel toe capped boots, hi-visibility

vests, hard hats, gloves, ear and eye protection.

A wall saw was used to cut through the pool walls that were 250 millimeters (9.8 inches) thick.

the floor was cut into 14 sections weighing 2.6 tons each.

the 13.3-meter-long (43.6-foot) rooftop swimming pool was to be cut and removed.

A Hilti Ds ts20-e wall saw was used to

perform the vertical cuts to the interior walls

of the pool, while the cuts to the floor of the

pool were made by a 35-horsepower core

cut floor saw from Diamond products. Hilti

also supplied a DD200 core drill to create the

picking holes for the crane rigging, while

Husqvarna K1250 and K960 cut and break saws

were also used for some parts of the cutting

work. slurry and waste material were collected

using a wVD2002 twin motor wet vacuum

to cut and remove the rooftop swimming

pool at the skycity Hotel, A1 Kiwi cutters

of Hyline construction and within budget.

Following the successful completion of the pool removal project, the

contractor has been further contracted by both Hyline construction and

Hawkins construction to work on other parts of the overall project.

“the pool removal work done at skycity Hotel gave us an opportunity

to show what we can do with our market-leading equipment and a

.former air force Base runway repaired by csda member


the airport site was originally an air base

for the U.s. Air Force before being handed

over to the city of Austin in 1993. personnel

from Bergstrom Air Force Base contributed

to every U.s. war effort before the base was

deactivated, and the U.s. Air Force reserve

continued to operate from the base until 1995.

Four years later, the airport began passenger

services and was renamed Austin-Bergstrom

international Airport, which now handles over

9,000,000 passengers a year.

Major updates took place at the airport

from 1996 to 1998 to make it a civilian airport,

including the addition of a second runway and

additional passenger and air cargo aprons.

However, the majority of the concrete on the

first runway had been in place since the air

field was built in the 1940s and had undergone

several rounds of patch-up work and repairs.

conditions that impacted this job included the

varying age and type of sealant used, as well as

the varying age and condition of the concrete.

the project was awarded to csDA member

interstate sealant & concrete, inc. (isc) of

waukesha, wisconsin. the contractor is a

certified Disadvantaged Business enterprise

and a certified women’s Business enterprise.

interstate was hired to work directly with the

airport’s Aviation Department to plan how the

work was to be done and devise a work schedule.

As various sections of the concrete runway had

been previously repaired and rehabilitated, saw

cutting with diamond tools was considered the

best option. this technique would minimize

additional spalling of the concrete.

“Due to the size and scope of the job, we

had considered joint plowing, a method that

utilizes a toothed jig to pull the old sealant out

of the joint, to rehabilitate the concrete. this


method was dismissed, however, because of

the varying age and condition of the concrete.

sawing with diamond blades provided us with

both the precision and the speed needed to

complete the project,” said gregg sment,

project manager for isc. From preliminary test

cutting, operators found that diamond cutting

left the joints crisper, which made the project

less labor intensive as less scraping was needed.

the first task was to remove the old

sealant from the existing joints. this involved

shaving both edges of the existing joint to

free up the bond on the old sealant with a

85-horsepower 8500D ride-on slab saw from

Husqvarna. once the sealant was free, it was

pulled or plucked from the joints by hand. this

process was carried out by five operators and

17 laborers and took 65 days to complete. All

processes ran simultaneously.

A 12,248-foot-long runway required sawing and resealing.

1 4 | JUne.11

After the old sealant was removed, the

joints were cleaned with custom-built wire

brush machines. the brushes used were

custom-made to isc specifications and were

manufactured to be free of oils and other

manufacturing contaminants. contaminant-

free compressed air was then blown into the

joints to clear them of any remaining sealant,

dust or debris, before the backer rods were

replaced. new backer rods were installed

and checked to make sure they achieved a

specific depth with a 2:1 ratio. Backer rod

sizes of 0.625 inches all the way up 1.25 inches

were used. Following this installation, the

joints were once again blown clean with

compressed air.

now that the joints had been prepared for

the installation of the new sealant, the team

from isc set up two graco sealant pumps to

apply 18,589 gallons self-leveling silicone from

Dow corning for the runway project. it took

45 days to complete the resealing.

A number of areas on the concrete

runway were identified as spalling. to repair

these areas, isc operators cut the perimeters of

the spalled concrete until they reached sound

concrete. the interior of the saw-cut area

was then removed before being cleaned and

sandblasted. Delpatch elastomeric concrete

from the D.s. Brown company was used to

fill back the prepped spalls, and this process

was finished by hand. the contractor repaired

287 spalled areas that covered approximately

1,175 square feet in total.

the biggest challenge for the csDA

member on this project was to avoid impacting

air passenger services, or at least keep any

necessary disruptions to an absolute minimum.

this included minimal interruptions at gate

areas and keeping runway closures to the

shortest possible time frame. the terminal

ramp was completed in six days. isc’s general

superintendent Dana gillespie and supervisor

Dan Hathaway coordinated with the airport

operations staff daily to keep runways open.

“these daily meetings were really important.

it was a continual, coordinated work effort to

get our crews around the airport while causing


the least amount of disruption possible, even

though it meant the crews went to different

work areas almost every day,” said Hathaway.

to create clean and safe joints for the new

sealant to be installed on runway 17r/35L

at Austin-Bergstrom international Airport,

interstate sealant & concrete, inc. used five

Husqvarna 8500D ride-on slab saws with 85-

horsepower engines. wire brush machines

were custom made by isc and used to prepare

the joints, along with silicone pumps from

graco and sand pots from schmitt. in total,

isc cut and resealed 1,319,062 linear feet of

concrete and repaired 1,175 square feet of

spalls in the concrete. on average, the team

completed 20,000 feet per day, which had

a positive impact on the project end date.

After being allocated 330 calendar days by

the airport’s aviation department to complete

the work, the contractor finished all scheduled

tasks in 133 days.

the contractor’s biggest concern, however,

was the heat. isc was given notice to proceed

on July 26, 2010, when average airport tem-

compressed air was blown into 1,319,062 feet of joints before the joints were sealed.

Dale thompson, air field project manager

critical that we minimized the amount of time

that runways were closed to airway traffic. isc

understood this, and the team scheduled and

As an example, we alloted 60 calendar days

a ll cores should be inspected at regular intervals and must be retired immediately if core cracking is observed. this is the standard outlined by

the saw Manufacturers Institute (sMI), occupational safety and Health administration (osHa) and the american national standards Institute (ansI). safety is the number one concern for each of these governing bodies and should be for any company.

Another important concern for concrete cutters, however, is how

to get the best performance and greatest value from diamond tools.

Following is valuable information regarding the manufacture of dia-

mond cores and cutter best practices. this information will help min-

imize the chance of core cracking, maintain safety and achieve the

strength, toughness and abrasion resistance to meet the demands of

today’s cutting applications and higher powered saws. the composi-

tion of steel also accepts laser-welded or brazed segments with mini-

mal changes to the mechanical properties. Laser cutting of the core is

the most desirable manufacturing process because punching, milling

and grinding can cause micro cracks and stress concentrations which

increase the likelihood of core cracking.

Core Cracking - Safety and Performance

heat treatment

Heat treatment is the process in which the steel core’s microstructure

is rearranged to control the mechanical properties like strength, hard-

ness and fatigue resistance. post tempering relieves stress and helps to

flatten the core after quenching. it is optimal to achieve a surface hard-

ness of rockwell 38rc for high-abrasion resistance. in addition, a lower

core hardness is desirable since it increases fatigue resistance and overall

core life. Hardness is also critical for flatness and tension since cores with

inconsistent hardness (spotty hardness) are difficult to smith and will

not hold tension. this will cause premature failure of the diamond tool.

surFace grinding

rotary surface grinding removes surface imperfections such as raw

material crown, scale and scratches. this helps to normalize and level the

surface, reducing the possibility of core cracking from stress concentrations.

1 8 | JUne.11

leveling, smithing and tensioning

proper leveling, smithing and tensioning insure longer life, better

performance and greater value for the contractor. cores that are leveled

and smithed flat will take and hold tension much longer than cores with-

out. tensioning, leveling and smithing will produce a core that runs true

longer. cores that run true will not wobble, heat up or fatigue nearly as

fast. this can significantly increase core life and performance.

machining the outside diameter

Machining the outside diameter is critical for the core balance and

concentricity. cores must be concentric to ensure proper segment mount-

ing and balance. this will also minimize the likelihood of hammering

while cutting, especially if the segments are also outside diameter ground.

the following are best practices that will help minimize core cracking,

increase performance and provide the most value from diamond tools.

Best Practices

select the correct tool For the joB

in order to specify the correct diamond tool for the job, operators

need to know the hardness of the material to be cut, the tool speed, the

equipment power, the cooling method and the mounting type. the cor-

rect diamond tool for the application will increase diamond tool perfor-

mance and reduce core cracking.

oPerational sPeed

the operator must make sure that the diamond tool is run at the cor-

rect revolutions per minute (rpm) to get the best performance from the

diamond tool and insure their safety and that of others in the work area.

over speeding and over feeding a diamond tool will cause premature

tool failure by increasing the amount of heat in the core and exceeding

the mechanical properties of the steel. the following table shows the

recommended rpm for 9,500 surface feet per minute (sfpm) blade speed.

equiPment care

Keeping equipment in good working condition is critical to the

safety of operators and the performance of diamond tools. without

proper maintenance and care of equipment, the life and performance

of diamond tools is greatly reduced.

Blade shaFt Bearings, collars and

mounting hardware

Vibration is one of the main causes of core cracks and blade fatigue.

Maintaining blade shaft bearings, collars and mounting hardware are

essential to reducing vibration and increase diamond blade perfor-

mance by minimizing hammering.

cooling oF diamond Blades

Heat is also a main cause of core cracking and loss of tension.

without tension, a diamond blade will not run true. it will contact

the sidewall, generate excessive heat and fail prematurely. therefore,

a wet blade must have ample water to cool it properly. For a dry cut-

ting tool, it is essential to operate within the blade manufacturer’s

recommended tool speed and not to apply too much side load. these

practices will help the blades operate within the design temperature

and help to insure diamond blade performance and life.

the information provided in this article will help contractors keep

their operators safe and maintain the profitable performance of dia-

mond tools. Any questions or matters that require clarification should

be directed to an official diamond tool manufacturer.

t he project description was straightforward. Demolish a 150-meter-tall (492-foot) concrete chimney stack at a redundant incineration plant in Hong Kong so that the site could be cleaned up for reuse. However,

the location of this particular chimney meant that it was not simply a case of bringing down the structure as quickly as possible, but bringing it down in a controlled manner that would not cause excessive noise or vibration. this was the challenge presented to one csDa contractor.

Take the Heat

the chimney, the tallest of its kind in Hong

Kong, was part of the Kwai chung incineration

plant that operated from 1978 to 1997. the

cynclindrical-shaped chimney tapered in

diameter from 12 meters (39.4 feet) at the base

to 6 meters (19.7 feet) at the top. the thickness

of the chimney stack wall also decreased from

the base to the top, from 1,000 millimeters

(39.4 inches) to 200 millimeters (7.9 inches). A

single, circular pile cap formed the foundation

of the structure, which was 16.5 meters (54.1

feet) in diameter and sat on 30 bored piles that

were each 1,200 millimeters (47.2 inches) in

diameter and measured 36 meters (118 feet)

deep. the aim was to level the incineration plant

before decontaminating the site. the plant and

surrounding land was owned by the Kwai chung

Drainage services Department and the land was

to be reused.

Attempting to demolish the stack using

traditional methods may have caused falling

debris to hit adjacent structurally sound

buildings or an elevated highway that was

located just 20 meters (65.6 feet) away from

the work area. the project was contracted by

china international water & electric corp., and

csDA member Modern concrete Drill cut co.,

Ltd of Kwun tong, Kowloon, Hong Kong, was

awarded the job.

the contractor suggested three different

methods for the demolition of the chimney.

First, scaffolding could have been erected to

enclose the external wall and the chimney

could be broken down by jackhammers. Debris

would be allowed to fall through the center

of the stack. the second idea was similar, and

involved using a demolition robot on a platform

attached to a crane. the robot could break the

concrete down from the top of the stack and

be lowered at intervals. Both of these methods,

however, caused too much noise, vibration and

debris for the general contractor, and so a third

was approved. this method involved the use of

diamond wire to cut the chimney into a series

of concrete rings that would be encased in a

protective scaffold setup during cutting and be

lowered to the floor by crane.

Modern Drill cut’s plan was to set up three

remote-controlled wire saws on the inside of

the chimney stack before cutting the concrete

structure into 55 circular pieces. each cut section

would weigh between 30 and 100 tons and

measure around 2 meters (6.6 feet) in height.

A 600-ton, 170-meter-tall (558-foot) crane was

to be positioned close to the work area to carry

the cut sections down to the floor, where the

concrete would be broken down into small

pieces for removal. operators could remain a

safe distance from the cutting area too. the

use of the wire saw provided minimal noise and

debris, and there were considerable savings in

time compared to other techniques.

A portable work platform was set up on the

ground around the perimeter of the chimney,

which included eight lifting brackets that would

allow the platform to be moved up or down the

stack with a good level of stability. the platform

was lifted to the top of the stack, where two

lifting supports were installed for gondolas that

would transport the cutting equipment to the

various levels during wire sawing. Hydrostress

FZ-2s handheld saws were used to form vertical

cut lines in the stack before the wire saw was

used to make the horizontal cut line and free

the section from the remaining structure. the

work platform was then lowered into position,

3 meters (9.8 feet) below the top cutting edge,

before the cut section was secured to the plat-

form and lowered to the ground by the crane.

this process took 10 hours to complete and was

repeated until the remaining section of the

chimney stack stood 10 meters (32.8 feet) from

the ground. this part of the structure was then

broken down using traditional demolitions meth-

ods as the risk of falling debris was much lower.

the obvious challenge for this csDA member

was the height of the structure being cut. strong

winds, particularly at the top of the 150-meter-

tall (492-foot) chimney, were a concern and the

contractor had to make sure that operators were

securely tied off. the other factor that the team

from Modern concrete Drill cut had to be aware

of was the proximity of surrounding buildings,

structures and the nearby highway.

the contractor considered many elements

when planning the work and made sure that

safety was a constant. personal protective equip-

ment was provided for operators, including har-

nesses for working at height. safe plant operat-

ing zones were identified and fenced off while

temporary lighting was installed inside the chim-

ney. Modern concrete Drill cut also installed fire

fighting equipment and emergency escape routes

were clearly marked. to keep the dust and debris

at the work area to a minimum, an extraction

fan was used to collect dust from the inside of

the chimney.

A Hydrostress 40-kilowatt FZ-2s wall saw

from tyrolit was used to create the vertical cut

lines on the chimney stack and three Hydrostress

sK-AD universal wire saws were used to perform

the larger horizontal cuts. over the course of

90 days, the team from Modern concrete Drill

cut co., Ltd. cut 2,800 cubic meters (98,881cubic

feet) of concrete with diamond wire to demol-

ish the chimney stack at the Kwai chung incin-

eration plant. A further 1,200 square meters

(12,916 square feet) of vertical concrete cutting

was performed.

the project was completed within the sched-

uled time period and allocated budget. the main

reason for this was that the concrete was not

as hard as initial surveys had suggested, so cut-

ting speeds increased. the other advantage for

the contractor was that the company had been

involved in the cutting and removal of chimneys

before and was well prepared for this job. As a

result, Modern concrete has now been chosen

to remove another chimney at the pandan incin-

eration plant, the tallest chimney in singapore.

Having the right tools and carefully planning any

job will ensure that a contractor doesn’t feel the

heat, even at an incineration plant.

Attendance rose an impressive 30 percent

from last year’s convention as contractors and

manufacturers from the concrete sawing and

drilling industry gathered in Bonita springs,

Florida, from March 8 to 12 for the 39th Annual

concrete sawing and Drilling Association (csDA)

convention and tech Fair. included in the large

number of attendees were new members, first-

time attendees and many past presidents of the

association.

A keynote presentation was given by clint

Longenecker, ph.D., entitled The Two-Minute

Drill, a leadership practice based on American

football. Longenecker’s presentation was well

received and some csDA members are already

taking steps to implement The Two-Minute Drill

into their businesses. “i was so inspired by the

seminar that i could not wait to get back to

the office and use some of the tools that were

provided. i learned that it is important to have

solid leadership, a good plan and consistent

follow-through in order for any change to

work,” says paul DeAndrea of DeAndrea coring

concrete cutters, and manufacturers who

supply contractors with diamond tools, came

looking for ways to improve and grow their

businesses as signs of an economic recovery

begin to appear. the number of exhibitors at the

csDA tech Fair also increased from 2010, with

the concrete sawing and Drilling association (csDa) has available the proceedings from the three roundtable discussions held during the csDa 2011 convention and tech Fair.

Discussions were held on the subjects of

Dispatching, concrete eco-practices and LeeD

certification and Hiring practices in the sawing

and Drilling industry. the proceedings from

these roundtables have been transcribed and

are now available to download through the

Members section of the csDA website.

Dispatchers are an integral part of every

contractor company’s day-to-day operations,

often asked to handle multiple responsibilities.

the Dispatching roundtable addressed a

dispatcher’s typical responsibilities, challenges

and areas for improvement. topics included

technology, effective techniques, customer

service, equipment location and “dispatcher

survival techniques.”

in order to stay competitive in today’s

market, many concrete cutting companies

have added new services. one of these services

is concrete and slurry recycling, which has

become a hot topic in recent months with an

increasing focus on “green” concrete practices.

Discussions from the concrete eco-practices and

LeeD certification roundtable covered how

LeeD credits apply to cutting companies and

how contractors can use recycling services to

increase profit.

the selection of new employees is one

the most important decisions a contractor can

make. Although there is no foolproof way of

guaranteeing a 100% success rate when hiring,

contractors can increase their odds significantly

by planning and setting out proper criteria

through each stage of the hiring process.

Discussions during the Hiring practices in the

sawing and Drilling industry roundtable touched

earlier this year at the concrete sawing

& Drilling Association’s 39th Annual

convention, Jim Dvoratchek, owner

of Hard rock concrete cutters, inc. of

wheeling, illinois, was elected president. it was

no surprise to members since Dvoratchek held

the position of vice president for the previous

two years, and the vice president assumes

the position of president. However, it was a

milestone for the association and Dvoratchek

as he became the first person to be re-elected

to the position for a two-year term.

Dvoratchek was first elected president of

csDA in 1999, twelve years ago. At that time,

he had been in the industry for 20 years and

was busy growing his company in the highly-

competitive chicago market. He was also a

founding member of the csDA insurance

program, which took quite a lot of time to

administer but he felt the time was right to

commit his own time and energy to the office.

now Dvoratchek has been in the concrete

sawing and drilling industry for over 30 years

and has, once again, committed his time and

energy to the office. But it is now a much more

seasoned professional taking the reins of the

association to give back to the industry that has

meant so much to him. the fact that contractors

fill offices in industry-wide associations does, in

many ways, relate to the life cycle of their own

businesses.

in 1979, he began his career in concrete

cutting as a helper/laborer before becoming an

estimator and cutter with the concrete sawing

& Drilling company. He then co-founded Hard

rock concrete cutters, inc. in 1987. He served

as secretary/treasurer for the new business and

then moved to president, a position he still holds

today. in 1995, Jim also helped to co-found and

serve as president of Hard rock company of

wisconsin and held the position of secretary/

treasurer for central illinois concrete cutters, inc.

At the time Jim joined csDA, he was keen to

learn from other cutters about concrete cutting—

techniques, applications and equipment. He

knew that he needed this kind of knowledge

to make his business a success and he had the

energy to dive in. “From the beginning, i saw

tremendous value in networking with industry

leaders,” says Dvoratchek. “i sought knowledge,

and the members of csDA were willing to

openly share their knowledge with me.” Hard

rock began to grow, as did his involvement

with csDA. He was able to implement the

things he was learning into his business and

share his own ideas with other members of

the association’s Board and committees. this

participation coupled with additional years in

business helped him to gain much knowledge,

forge important business relationships and form

strong friendships—all things that can help any

young business leader.

now that Hard rock had developed into a

large-scale operation, and now that Dvoratchek

is working on a business succession plan with a

trusted team, including some of his children,

he now feels he has the time and resources

to commit to the position of president. For

some, this may have been the perfect time

for a guy like Dvoratchek to slow down and

reap the benefits of his years of hard work, but

experience, especially in the past few years, has

taught everyone that it is not enough to rest on

their laurels anymore.

next year marks the 40th anniversary of

csDA. Many of the industry leaders who helped

grow the association in its infancy and make

it such a valuable organization are now ready

to step aside from the day-to-day operations

of their own companies and help new leaders

develop. in Jim Dvoratchek, the association has

a proven leader who has returned to help the

association continue moving forward. He is a

great example of the kind of people who make

up the membership of csDA. the association is

fortunate to have dedicated people who are

willing to get back in the saddle and continue

to steer it in the right direction.

Nutrition for Job Performance

core HealTH

h ealthy diet, superfoods, low-fat,

high-protein and counting carbs—

all buzzwords we have heard on

television, read in books, magazines and on

the internet. there is a wealth of information

concerning nutrition out there that, at times,

can seem conflicting and often confusing.

so who is right and what is really important

when it comes to eating a healthy diet and

what impact does this have on your job

performance? the answers may surprise you.

while healthy nutrition can be a confusing

subject, the basics are not. Yes, there are fad

diets and extreme weight-loss plans that may

work for some, but the easiest way to eat

healthy is by following a simple plan that will

not only make your body healthier, it will also

improve your mood, raise your energy level

and keep you healthy. All of these elements

contribute to better job performance.

people who consistently eat a healthy

diet—not just cutting calories—reduce their

risk of cardiovascular (heart) disease, cancer

and other diseases and infections. Body weight

is often lower, reducing stress on muscles and

joints and healthy eaters fatigue less easily. A

healthy diet also contributes to an efficient

immune system and better overall health.

the basics of a healthy diet are made up of

five main components: carbohydrates, protein,

fats, vitamins and minerals. carbohydrates are

the body’s fuel source and are made up of

two types: simple and complex. simple car-

bohydrates give the body short, quick bursts

of energy and come from foods like fruits,

juices and milk. complex carbohydrates have

the ability to be stored in the body for longer

periods of time to be used as energy. examples

of complex carbohydrates are whole grains,

pasta, bread and vegetables. All forms of car-

bohydrates are broken down by the body into

glucose, which is then converted into energy.

protein is responsible for building and

repairing muscles, ligaments, tendons and

other tissues. protein is not a significant energy

source, and excess protein will be stored as fat.

Fats are a concentrated energy source and

are also used for cell function, protection of

vital organs, supplying essential fatty acids and

are used to transport vitamins throughout the

bloodstream. there are three main types of

fats: trans, saturated and unsaturated.

• trans fats are usually added during

the cooking process, often by frying,

and should be avoided as they raise

triglycerides and LDL (bad) cholesterol.

• saturated fats from meat, dairy and

some oils also increase cholesterol and

therefore risk of heart disease. they

should be consumed sparingly.

• Thetwotypesofunsaturated fats, mono

and poly, are considered “healthy” fats

and lower cholesterol levels and raise

HDL (good) cholesterol. polyunsaturated

fats come from vegetable and fish oils,

while monounsaturated fats come from

olive oil, peanut oil, avocados and most

nuts.

Vitamins and minerals provide no energy,

but are important components that help sup-

port the body’s essential functions.

while every person is different, the same

general principle applies. if more calories are

consumed than burned, the person will gain

weight. if more calories are burned than con-

sumed, the person will lose weight. Younger

and active people will require more calories

daily, while older and sedentary individuals

will require less. in general, men will need

to consume more calories than women. see

Figure 1 for more information about daily

caloric intake. Again, these percentages are

dependent on each individual, their age and

activity level. Men typically need more protein

than women, while active individuals will need

more carbohydrates than sedentary people.

A healthy diet always starts with a good

breakfast. Job performance will suffer if break-

fast is an afterthought and comes in a greasy

bag from a fast food restaurant. Breakfast

should be high in carbohydrates for energy

and high in protein. this helps keep hunger

at bay until lunchtime. easy healthy breakfast

options include: oatmeal with fruit, whole-

wheat toast with peanut butter and jelly or an

english muffin with peanut butter. Fruit juice

or milk is a good beverage option.

Lunches and dinners should include a high

percentage of protein, some carbohydrates,

and lots of fruits and vegetables. Lunch needs

to keep you full until dinner, so protein is a


priority. A reasonable amount of carbohydrates

should be added to give you energy. Lunch is

also an easy place to add fruits and vegeta-

bles, possibly with an apple and peanut but-

ter or carrot sticks and hummus. Dinner could

include anything grilled (chicken, pork or fish)

and a serving of vegetables, such as a salad or

steamed vegetables. Dinner should be light on

fats and heavy sauces or dressings.

the term “superfoods” is used frequently,

but with good reason. it usually describes foods

that are not only healthy, but also contain an

abundance of nutrition. these foods should

be included in your diet as much as possible.

• Black beans—low in fat and packed with

fiber and protein

• Broccoli rabe—low in calories, high in

vitamin A, vitamin K and sulforaphanes,

which protect against stomach, lung and

breast cancers

• Green tea—high in antioxidants and

protects against viruses, infections and

cancers

• Kiwi—the most nutritionally dense fruit,

contains many vitamins and minerals

• Mackerel—high in heart-healthy omega-3

fats (good fats) and low in mercury

• Pork tenderloin—low in fat and calories,

high in vitamin B6

• swiss chard—similar to spinach, high in

vitamins A and K

• Walnuts—high in omega-3 fats

Anyone will benefit from a heart-healthy

diet that includes whole grains (providing fiber

which lowers cholesterol), healthy fats (mono-

unsaturated and omega-3) and lots of fruits

and vegetables. Here are some examples of

heart-healthy foods:

caloric intake carbohydrates Protein Fats

Active Males 2,400–3,000 45–65% 25–35% 20–35%

Figure 1. Daily caloric intake and nutrient recommendations. numbers will vary due to age, activity level and individual specifics.

• Fish—especially salmon, mackerel and

herring, which all contain omega-3 fats

• cooking oils—olive, sunflower, peanut

and sesame oils all contain high levels

of monounsaturated fats, which lower

cholesterol, and vitamin e, which lowers

LDL (bad) and raises HDL (good) levels

• Fruits—contain fiber, phytochemicals

and lycopene, all of which lower the risk

of developing cardiovascular disease

• Dark, leafy greens—spinach, kale,

greens, arugula, swiss chard and bok

choy all contain folate (a mineral) which

decreases heart disease risk

• nuts—peanuts, cashews, almonds,

walnuts and others all contain fiber

and omega-3 fats which decrease

triglyceride levels as well as contain

monounsaturated fats, which decrease

LDL levels and raise HDL levels

eating a healthy diet does not need to

be complicated, expensive or time-consum-

ing. the best plan is to take one step at a

time, gradually making a permanent lifestyle

change. the benefits of improving your health

far outweigh any negatives, such as extra time

or money spent in the long run. if the result is

improved job performance, better quality of

life and longer life, any extra effort is worth

the payoff.

Ten Ways to Cut Fuel Costs

By Jack Lee

the Business of Business

r emember the good old days, when prices at the pump were below two dollars per gallon

and usually stayed there? Well, the good old days are gone and today the world is a place where fuel prices seem to change by the hour. now pundits speculate on living with oil prices running as high as $200 a barrel.

Many consumers have adjusted their life-

styles. some try to drive less or have chosen

to carpool, while others have traded their

gas-guzzlers and opted for more fuel-effi-

cient vehicles, including hybrids. For compa-

nies, the good old days meant simply having

employees fuel up and head out to the job.

Little attention was paid to managing fuel. in

the past year, the high price of oil is cutting

deeper than ever into company profits, caus-

ing owners and managers to adopt a new fuel

consciousness. Fuel management is a necessity.

costs. Allowing an engine to idle more than

three minutes causes expensive damage, harms

efficiency, shortens engine life and increases

maintenance costs. it all adds up. companies

can initiate a campaign to reduce idling time

and reward participants if their fuel consump-

tion drops.

3) start oFF slower

this is another lesson that some drivers

must learn. Accelerating aggressively from

standing starts wastes fuel and saves less than

three minutes of driving time per hour. it can

even result in using 40 percent more fuel and

increase toxic emissions by 400 percent! Drivers

should be encouraged to ease up on the gas

pedal to increase efficiency.

4) slow down

Driving at excessive speeds is not only

dangerous but it also wastes fuel and creates

higher levels of toxic emissions. speeds over

60 miles per hour drastically impact fuel effi-

ciencies while vehicles traveling at 75 miles per

hour can use 20 percent more fuel than those

traveling at 60 miles per hour. trucks travel-

ing at 75 miles per hour use 50 percent more

fuel than those traveling at 60 miles per hour

and they also emit 100 percent more carbon

monoxide, 50 percent more hydrocarbons and

31 percent more nitrogen oxides.

you can’t control the price of fuel, but

you can control your fuel consumption.

the answer is fuel management.

Any company can improve its fuel effi-

ciency. it takes work and commitment, from

personnel in the head office to employees on

the road and at the job sites. More and more

companies are now making changes in oper-

ating practices to cut costs and be prepared

for even higher costs in the future. to help

contractors adjust to these historic fuel prices,

here are ten ways to cut fuel costs.

1) train and educate drivers

this starts with the people who have

their foot on the gas pedal. Drivers can con-

trol fuel consumption each time they fire up

their engines, and proper training can improve

fuel efficiency, economy and emissions. Hard

acceleration, speeding and idling are the big-

gest causes of fuel waste. companies can ini-

tiate a training course for drivers and reward

participation.

2) decrease idling

Drivers should be aware of the length of

time that engines idle. Machinery and equip-

ment should no longer be left running all day

long. excessive idling can add to fuel costs by

as much as 50 percent and can shorten the

life of engine oil by 75 percent, adding more


5) lose weight

excess weight places unnecessary strain on

a vehicle’s engine and greatly affects its fuel

efficiency. By removing as little as 100 pounds

of weight from a car or truck, drivers can sig-

nificantly improve the vehicle’s gas mileage.

companies should encourage drivers to check

their vehicles and remove any unnecessary

weight. this can include tools and equipment

that will not be required for the day’s work.

6) use a Fuel management system

this is the most powerful way to lower

fuel costs and increase productivity. Available

systems range from basic onsite refueling,

which saves up to 20 minutes in wasted

time and fuel each day, per vehicle, to

automated fuel tracking that details every

gallon pumped into every vehicle by date,

time, quantity and fuel type to telematics,

which measures overall fuel efficiency, vehicle

performance, tracks fuel waste due to idling

and speeding. it also identifies critical areas

to improve efficiency and reduce fuel costs

and emissions. the technology exists so that

companies can accurately track and monitor

fuel consumption, one vehicle at a time.

7) uPgrade the Fleet

whenever possible, companies should

invest in modern, fuel-efficient vehicles.

Modern diesel engines are far more fuel-effi-

cient and perform better with modern diesel

fuels such as ultra-low sulphur diesel and bio-

diesel. though it may seem expensive, new

diesel vehicles can save thousands of dollars in

maintenance, fuel and productivity per vehicle.

it is good practice to measure each piece of

equipment for fuel efficiency and get rid of

those that are not performing well.

8) tune-uP vehicles regularly

companies should employ a stringent,

well-managed maintenance policy. Unfor-

tunately, too many companies adopt a “fix it

when it breaks” attitude. A well-maintained

vehicle performs better, improves fuel

efficiency, reduces toxic emissions and, in the

long run, costs less to maintain.

9) PumP it uP

proper tire inflation improves gas mileage.

statistics show that improperly inflated tires

can cost up to two weeks worth of fuel per

year. employers should take this statistic and

apply it to the number of trucks in their fleet.

two weeks per year per vehicle can add up

to thousands of dollars in lost profits. in addi-

tion, proper tire inflation results in improved

vehicle and braking performance, and increases

tire life.

10) imPlement advanced moBile

asset management technology

there are a growing number of businesses

that can supply this technology. companies

can measure and manage fleets better when

the right information is made available.

tracking miles traveled, average speed and

engine efficiency is very important in cutting

fuel costs. this information will help drivers

and dispatchers optimize routes with bet-

ter planning. Mapping software and gps will

eliminate thousands of unnecessary miles per

week. Less time on the road means less fuel

consumed, less wear on vehicles, decreased

expenditures and overall increased produc-

tivity, plus lower toxic emissions.

once a company commits totally to man-

aging its fuel usage better and drivers are

encouraged to cut out some of their bad fuel

habits, positive results will follow. the goal

is to then have everyone stick with this new

approach since there is a good chance that

fuel prices will only continue to go up.

Port of TampicoBerthing Structure Removed with Wire Saw

when the support pillars of a large concrete berthing structure at

a major Mexican shipping port began to corrode, the authorities

contacted a professional cutting contractor to demolish and

remove the platform. this work was to be done quickly, before the support

pillars gave way and allowed the structure to fall into the water, which would

create a hazard for passing ships.

the port of tampico is situated on the east coast of Mexico in the state of tamaulipas. tampico

was founded in 1554 and the city was declared an official deep-sea port in 1824. today, the port

has over 20 large docks in public and private shipping terminals, some of which can handle up

to 50,000 tons of cargo that arrives by ship from the gulf of Mexico. the total distance of these

docks and terminals is over 4,000 linear meters (13,123 feet).

the decaying concrete berthing structure measured 6 meters long, 6 meters wide (19.7 feet)

and stood 2.2 meters (7.2 feet) tall from the base of the port’s sea bed. the 0.7-meter-thick

(2.3-foot) berthing platform was supported by eight 61-centimeter-diameter (24-inch) steel

A berthing structure required removal at the port of tampico.



pillars filled with reinforced concrete. some

of the corroded pillars had crumbled, and the

decreased support in these areas had caused

others to break, due to the shift of balance

and weight.

in september 2010, the Universidad del

carmen (carmen University) collaborated

with peMeX of central Mexico to set up a

project to remove the platform and some

of its pillars. the university enlisted the

help of csDA member soluciones tecnicas y

profesisonales ADrA s.A. de c.V. (ADrA) of

Leon, Mexico, to cut sections of the concrete

structure and retain some of the pillars to test

their structural integrity and define what had

caused the pillars to fail. “our wire saw work

at the collapsed tonola Bridge (featured in the

september 2010 issue of Concrete Openings)

enhanced our reputation and was noticed

by those involved in this project,” said raul

Bracamontes, owner of ADrA.

the contractor decided that this job would

also be well suited for cutting with diamond

wire, as completing work in the water and

around such a busy waterway as the port of

tampico would require minimal noise and

vibration. this technique would also create

far less debris than traditional demolition

methods. A plan was drawn up to cut the main

concrete platform into nine pieces and retain

two of the support pillars for testing. the

cutting work was scheduled to be completed

15 days from commencement, so time and

speed were of the essence. in addition, the

team from ADrA had to factor in the structural

decline of the berthing platform and pillars.

the sections of concrete had to be removed

in such a way as to not disturb or collapse the

remaining structure.core holes were drilled for wire saw runs and for crane rigging.

the structure was cut into nine sections using diamond wire cutting techniques.

3 6 | JUne.11

to begin the cutting work and prepare the wire saw setup,

the contractor used a Hilti DD200 core drill with a 6-inch-diameter

core bit from Husqvarna to create eight holes 0.7-meters (2.3-

feet) deep in the concrete platform. these holes would allow the

diamond wire to pass through to set up runs for the wire saw

and allow crane straps to be fastened around the sections once

cut free. the core drilling of the berthing platform took one

operator eight hours to complete. A 5,500-watt generator was

used to supply power while water was supplied by a submergible

pump with a 0.5-inch hose.

once the structure had been core drilled, the cut lines for

the sections were marked out and the wire saw was set up.

the Husqvarna cs2512 unit was anchored to the concrete and

pulleys were set in place to create the wire runs. power was

supplied by a 125-kilovolt amperes generator and two electric

pumps connected to one hose provided water to cool the wire

during cutting. A diver was sent into the water to pass the wire

around the underside of the structure, and also to inspect the

structure and its support pillars. if any rebar was found to be

obstructing the diamond wire run, the diver would return to the

water immediately and remove the rebar with a cutting torch.

the contractor made a cut 6 meters (19.7 feet) in from the

edge of the 0.7-meter-thick (2.3-feet) platform to get the first

concrete section free. the first piece to be cut free weighed

15 tons and was removed by a 40-ton crane. wedges were set

in place as cutting progressed, and after the first section was

removed, the remaining structure was inspected for stability.

this process was repeated for each of the nine concrete sections

removed. it took the wire saw five hours to cut free one section.

After all nine specified sections of the

concrete platform were cut and removed,

the team from ADrA turned their attention

to the 2-foot-diameter pillar structures. the

task involved cutting and removing two

pillars and transferring to land, where they

were to be cut into three pieces to evaluate

their internal structure. this would help

the customer understand what failings had

taken place and how to guard against further

breakages on other structures. to remove the

pillars, ADrA first used a diver to extract hard

mud from around the bases. this eliminated

friction between the soil and the pillars. the

pillars were then extracted from the water by

crane and laid out on land. operators then

used a Husqvarna K1250 gas-powered hand

saw with a 16-inch-diameter blade to cut the

pillars into smaller sections.

the main safety concern for Bracamontes

and his team was the busy location and crum-

bling condition of the berthing structure. the

extent to which the structure was decayed

was not fully known, and so constant check-

ing of its integrity was performed to guard

the first part of the platform to be cut free weighed 15 tons.

against any sudden breakages or collapses. the

job was planned to cut nine separate pieces

free rather than one large chunk. the port of

tampico continued to allow ships to pass by

the cutting area, so care had to be taken to

make sure no debris or dust from the work

interfered with these vessels.

in addition to these conditions, the

contractor had to keep one eye on the skies.

During the work, Hurricane Karl touched down

in Veracruz, just south of tampico. this category

3 hurricane did not directly affect the port, but

its strength was enough to cause strong winds

in excess of 75 miles per hour and heavy rainfall

(12.7 to 25.4 centimeters or 5 to 10 inches) in

the tampico area and delay the cutting work.

working around a large expanse of water on

a broken structure meant that all members of

ADrA’s cutting team had to be aware of all

safety procedures and wear the appropriate

personal protective equipment.

to complete the cutting work and save

the corroded berthing structure from collapse,

ADrA used a DD200 core drill from Hilti with a

6-inch-diameter core bit from Husqvarna. the

35-meter (114.8-foot) length of 10-millimeter-

diameter (0.4-inch) diamond wire and cs2512

wire saw were also supplied by Husqvarna,

along with one K1250 hand saw. the contrac-

tor cut 25.2 cubic meters (889.9 cubic feet) of

concrete from the structure’s platform and

cut through two 2-foot-diameter steel pillars

filled with reinforced concrete. Before this,

eight holes were drilled 0.7 meters (2.3 feet)

deep and 6 inches in diameter for the diamond

wire runs and for attaching straps. this whole

process took 10 work days to complete.

“the project did have certain risks, but we

planned the work well and made the right

decisions,” said Bracamontes. “the customer

is now considering us for the removal of more

concrete structures at the port in 2011 as they

like our system,” he added.

Decayed pillars were removed from the water and cut into sections for testing.

the work was to be performed after 5:00 pM when most employees

in the building had left for the day. the building contractor, Masters

construction and Development of tampa, Florida, had previously used a

jackhammer for similar jobs but had learned that diamond drilling would

be a better alternative for this job. this application would provide less

noise and vibration.

true Line worked with Masters to scan the floor slabs for obstructions

before starting the drilling work. All three holes were drilled without

problems and within the three-hour time slot

specified. this allowed plumbing contractors

New OSHA Guidance on Employee PPE

By Mark A. Lies II and Elizabeth Leifel Ash

since 1974, osHA has had regulations

in effect that required employers to

provide personal protective equip-

ment (ppe) to employees as protection for

eyes, face, head and extremities, including

protective clothing, respiratory devices and

protective shields and barriers. in addition, the

employer was required to ensure that employ-

ees used the ppe when exposed to the hazard

and that the ppe be maintained in a sanitary

and reliable condition so that it would func-

tion as intended. throughout the history of

these regulations, there have been ongoing

disputes between employers and osHA over

which specific ppe the employer would be re-

quired to provide at no cost to the employee.

this article discusses new guidance issued by

osHA on February 10, 2011 that clarifies recent

revisions to osHA’s ppe rules.

osHA issued new rules clarifying the

employer’s obligation in 2007 (Federal register

Vol. 72, no. 220, pp. 64342-64430). the final

rule became effective on February 13, 2008

and required implementation by May 15, 2008.

in February of this year, osHA issued new guid-

ance to compliance officers to assist them in

conducting inspections related to ppe. the

guidance clarifies what type of ppe employ-

ers must provide at no cost and sets out the

Agency’s enforcement policies concerning ppe.

the guidance can be found at http://www.

osha.gov/oshDoc/Directive_pdf/cPL_02-01-

050.pdf.

emPloyer duty to conduct

PPe assessment

As a starting point, existing osHA regu-

lations have long required an employer to

conduct a hazard assessment to determine

if hazards are present, or likely to be pres-

ent, which necessitate the use of ppe (29 cFr

1910.132(d)(1)). in this regard, employers are

required to conduct a broad assessment of

the various aspects of the job to determine

whether the following hazards to employees

may be present:

• Hazardsofprocessorenvironment

• Chemicalhazards

• Radiologicalhazards

• Mechanicalirritants

it should be determined if any of these

items are likely to be encountered in the work-

place in a manner capable of causing injury or

impairment to the body. this injury or impair-

ment can be through the following:

• Absorption

• Inhalation

• Physicalcontact

this assessment requirement has

existed since 1994 and employers

are already subject to citation

for failure to perform it. Many

employers are unaware that

there is a requirement for

a written certification that

such hazard assessment has

been performed (29 cFr

1910.132(d)(2)), which

osHA will request if an

inspection is conducted

involving ppe compliance.

the organization will cite the

employer for a violation if this

certification is not forthcoming.

emPloyer duty to Provide PPe

and training

once the employer has

completed the hazard assessment,

the employer must provide the

ppe to the employee, train the

employee in its proper use and

enforce the use of ppe through

appropriate discipline. this training

should include the following aspects:

• WhenPPEisnecessary

• Howtoproperlyuse,adjust

and wear ppe

• ThelimitationsofthePPE

• Thepropercare,maintenance,usefullife

and disposal of ppe

the training should also require the

employee to demonstrate to the employer

that the employee understands what has been

taught (29 cFr 1910.132(f)(2)). Finally, there

is an existing requirement for the employer

to generate another written certification

that the employee has understood the fore-

going training (29 cFr 1910.132(f)(4)). osHA

can issue citations for failure to prepare such

certification.

emPloyer duty to Pay For PPe

obviously, once the employer has deter-

mined that ppe is required, the issue arises

over who will pay for it—the employer or

the employee. in an effort to finally clarify

who pays for ppe, osHA began rule-making

in 1999 which resulted in the ruling that took

effect in 2008. the ruling adds a new subpart

for each industry sector subject to the rule.

For general industry, the new rule is desig-

nated as 29 cFr 1910.132(h) – payment for

protective equipment. this subpart defines

the new clarifications regarding payment for

ppe. importantly, while section 1910.132 gen-

erally relates to ppe, there are other osHA

standards that specifically require ppe, includ-

ing the blood-borne pathogen standard, the

grain handling standard and a host of stan-

dards that are specific to regulated airborne

contaminants such as lead and asbestos.

the regulation generally requires that all

protective equipment used to comply with

section 1910.132, including ppe, must be

provided to employees at no cost to them.

According to the new guidance document,

the employer must provide the following ppe

at no cost to the employee if used to comply

with an osHA standard:

• Metatarsalfootprotection

• Rubberbootswithsteeltoes

• Shoecoversliketoecapsandmetatarsal

it is very important to note, however, that

this list is not all inclusive. the employer’s ppe

hazard assessment will be the determining

factor for which ppe is required for the job,

thereby imposing an obligation to pay for it

upon the employer.

Again, this list is illustrative, and many

other items may be excepted based upon the

employer’s hazard assessment.

duty to Pay iF PPe lost or

intentionally damaged

while the employer must pay for required

ppe within its hazard assessment, the employer

has the right to require employees to pay for

ppe if the employee loses or intentionally dam-

ages the ppe (29 cFr 1910.132(h)(5)). this situ-

ation will arise when the employee reports to

work without his or her ppe or the employer

conducts their walkaround of the worksite

and observes that ppe is so damaged and not

due to normal wear and tear. the employer

can determine if the damage is intentional. At

this point, the employee cannot be allowed to

work unless the ppe is replaced. Furthermore,

the employer can require the employee to pay

for the replacement ppe and follow its normal

disciplinary policies against the employee for

losing or intentionally damaging ppe that is

company property.

it should be noted that if the ppe is dam-

aged due to normal wear and tear caused by

job activities or environment, the employer

must replace the ppe at its cost and the

employee is not subject to discipline.

emPloyee-owned PPe

in many instances, employees may vol-

untarily provide items which constitute ppe,

and if so, the employer has no obligation

to pay for the ppe. However, the employer

must evaluate and determine that this ppe

is at least as effective as that required by the

employer’s hazard assessment. if it is not at

least as effective, the employer must provide

the ppe. in addition, any time the employee-

supplied ppe becomes no longer functional,

or the employee declines to provide it, the

employer’s duty to provide ppe will become

effective. similarly, an employer does not

have an obligation to pay for ppe requested

by an employee that exceeds the ppe require-

ment, as long as the employer provides ppe

that meets the standards at no cost to the

employee. even if an employee elects to use

upgraded or personalized ppe, however, the

employer must nonetheless ensure that the

ppe is adequate to protect the employee from

hazards present in the workplace, is properly

maintained and is kept in a sanitary condition.

oFF-site use oF PPe

An employer may allow an employee’s

ppe to be used off the job site. However, the

off-site use of the ppe does not relieve the

employer of its obligation to pay for the ppe

where required. where ppe is not required to

be worn away from the job site, the employer

may require employees to keep ppe on-site

and secure, as in a locker or locked cabinet, and

may also require an employee to turn in his or

her ppe at the termination of employment. if

the employer requires employees to leave non-

specialty eyewear or non-specialty footwear at

the job site, then osHA has taken the position

that the employer must provide those items at

no cost to employees.

Potential citation liaBility

it is important to note that if the agency

determines a violation has occurred regard-

ing failure to train employees, properly equip

them with ppe or to enforce the use of ppe, the

employer faces liability for citations. this liabil-

ity can be significant if the agency decides to

issue citations on a per employee basis, that is,

a separate citation with a separate monetary

penalty for each employee found out-of-com-

pliance for conditions such as not wearing hard

hats, protective eyewear or hearing protection.

if a number of employees are found out of

compliance, the penalties can quickly multiply

in the thousands of dollars of monetary liability.

since osHA is now focusing on ppe com-

pliance, employers must now focus on their

compliance efforts, including:

1. Verifying their initial ppe hazard

assessment and written certification

2. confirming employee training on the use

of ppe and written certification

3. Developing policies on issuance of ppe,

use of employee-supplied ppe, inspection

and replacement program for use of

ppe and finally, discipline for loss or

intentional damage to ppe

By taking these steps, employers can

limit their risk of osHA citations and educate

employees on the care and maintenance of ppe.

t he alliance between the concrete sawing & Drilling association (csDa) and the occupational safety and Health administration (osHa) is now

in its fifth year and continues to educate contractors, prevent on-the-job accidents and injuries and provide vital materials to advance a safe work environment for sawing and drilling professionals. Here is the latest news from the alliance Program.

alliance Program construction roundtaBle

discusses osha comPliance assistance Products

More than 20 representatives from 14 Alliances, including csDA past

president Doug walker of Atlantic concrete cutting, inc., gathered at

the osHA Alliance program construction roundtable meeting at the

Department of Labor in washington, D.c. in February 2011. Assistant

secretary of Labor for occupational safety and Health Dr. David Michaels

provided updates on a number of subjects, including osHA’s 40th anni-

versary, the regulatory Agenda and the Fiscal Year 2012 Budget request.

to enable them to share information about osHA activities with

their members and downstream customers, the group received osHA

updates on topics including osHA’s Distracted Driving initiative, injury

and illness prevention programs, cranes and derricks, silica, confined

spaces, residential fall protection and the severe Violator enforcement

program. the group also heard overviews of osHA’s Most Frequently

cited standards in construction as well as the national institute for

occupational safety and Health’s prevention through Design and

national occupational research Agenda initiatives. in addition, Mary

watters, Director communications Department, cpwr - the center for

construction research and training, gave an overview of the electronic

Library of construction safety and Health, which is a collection of free

information on construction safety and health in english, spanish and

other languages.

in addition, members of the group provided feedback on drafts of

product ideas that were developed at the last roundtable, including

construction safety design solutions that address beam columns, fixed

ladders and stairways. these designs focus on solutions that will help

prevent falls in the construction industry. the group previously completed

six construction safety design solutions that are being reviewed by osHA

to determine if they can be the basis for osHA compliance assistance

products. since 2004, roundtable participants have developed a variety

of free compliance assistance materials for workers and employers.

osHA holds two meetings of the Alliance program construction

roundtable per year to bring together participants with common

interests. the meetings offer the opportunity for participants to share

construction-related information about Alliance activities and successes,

network with other Alliances, and develop compliance assistance tools

and resources.

Six Secrets to Earn an “A” Grade on Your Workers’ Compensation Insurance Report Card

By Curt Dumbleton

w orkers’ compensation is consid-

ered the red-headed stepchild of

the insurance industry. it usually

loses money for insurance companies, pays less

commission to insurance agents and reminds

employers of employee sick time or time off.

therefore, it doesn’t generally get the atten-

tion it should.

As a company owner or employer, you

probably find it difficult to control your most

expensive employee benefit, health insurance,

which increases 15 to 25 percent every year.

However, you can have an immediate and

powerful impact in controlling your second

largest employee benefit, which is workers’

compensation. workers’ compensation is the

only insurance cost business owners have com-

plete control over, yet few take advantage of

this situation. As a matter of fact, most busi-

ness owners are often overcharged for their

workers’ compensation insurance.

so, what are the six secrets to controlling

workers’ compensation costs and preventing

overcharges?

understand that workers’

comPensation is a Process with

deFined stePs and dates to Follow.

workers’ compensation is a defined pro-

cess. Because you receive an audit after your

current year workers’ compensation policy

expires, you don’t know your final cost until

after the audit. in addition, you have already

renewed the policy for the following year

and the renewal cost may not be accurate.

the solution is to prepare for your workers’

compensation audit like you would prepare

for your income tax audit.

it is advisable to have a workers’ com-

pensation expert at your side. Based on infor-

mation from the institute of workcomp

professionals at www.workcompprofession-

als.com, 75 percent of all audits have errors in

them. Most of these errors lead to employers

being overcharged.

understand the whole exPerience

modiFication rate Process.

Business owners, not the insurance com-

pany, pay for employee injuries. when an

employee suffers an injury, your experience

modification factor is affected. typically, sev-

eral small injuries can cause a more rapid

increase in your modification factor than one

large injury. thus, injuries lead to increases in

your premium. in addition, multiple injuries

may lead to lost dividends, premium increases

and the cancellation or non-renewal of your

policy. Managing a mod rate requires manag-

ing employee health and fitness on the job.

know what a minimum modiFication

Factor is and how to reach it.

Knowing how much money you may be

losing because you are not at your minimum

modification factor is critical so that you can

do something about it. today, many compa-

nies who bid jobs cannot even be included

in the bidding process if their modification

rate is over 1.00. each business has a minimum

modification factor set by a ratings bureau.

Discover yours and reach it. Depending on how

large your payroll is, the difference between

what you are paying now and what you would

be paying at the minimum modification rate

could be anywhere from hundreds to thou-

sands of dollars. if your modification factor

is not at its minimum, any costs incurred are

affecting your bottom line. when your modi-

fication factor is at or near the minimum, your

company is in a much better position.

develoP a return to work Program

that works Both For you and your

emPloyees.

Focus on bringing injured workers back to

work as quickly as possible. create a positive

work environment in which employees are

valued and their absence is noted. A strong

return to work program can be the key to

achieving your lowest modification factor.

when an employee is off the job, a com-

pany can experience increased costs in over-

time, dips in morale and lower productivity.

to work program can be downloaded from

how workers’ comPensation works

and communicate with them when

they are injured.

Make sure your employees know how

workers’ compensation works and what they

should do if they are injured on the job. As an

employer, you need to know immediately when

an employee is injured so you or your represen-

tative can get the employee the best treatment

possible. the goal is to have them miss the least

amount of work possible.

workers’ compensation is the insurance cost

over which you have absolute control. Do not be

overcharged and do not pay more than you are

legally obliged. Be ruthless in working toward

an “A” grade on your experience modification

factor scorecard.

when you manage the audit process, work

hard to achieve your minimum modification fac-

tor. create a clinic relationship, provide return

to work programs and educate your employees

on how workers’ compensation works. Maintain

a safe workplace and culture of safety through

training and building employee morale. By doing

these things you can drive your costs down. stop

losing money on your workers’ compensation.

pensation audit? company owners or managers can

James Bond Test™ MK III Developed By James InstrumentsJames Instruments, Inc. has developed the James Bond Test MK III

test unit for measuring the bond strength, tensile strength and adhesion

strength of concrete, asphalt, tile, concrete repair or other overlay material

by the direct tension or pull-off method. The test unit can be used to

verify the quality of the material being tested as well as determine the

adhesion strength of shotcrete, tile, epoxies, paint and other repair

materials, mortars or coatings. The test involves bonding a circular steel

disc to the surface of the material being tested by means of an epoxy resin

adhesive. A controlled tensile force is then applied to the disc and failure

will occur at the weakest point—either in the host material or in the bond

between overlay and host material. The new tester features two calibrated

gauges that display the maximum load and mechanical damping and has

an adjustable alignment plate with built-in leveling facility for both vertical

and horizontal pulls. For more information, visit www.ndtjames.com or email [email protected].

Concut, Inc. Announces New Double-Life Wall Saw Blade

Concut, Inc. is pleased to introduce the new WS-MAX5

wall saw blade. This unique blade features laser-welded

segments that are .800-inch tall—twice the height of

conventional blade segments. These tall, sandwich segments

are designed to maintain their width and to extend blade life

to approximately twice the normal expected life. Since the

WS-MAX5 has a wide .225-inch segment (matching the

thickness of standard diamond chain), operators can avoid

jamming and side clearance problems. The blade is also

available in .187-inch and .250-inch versions. For more information, contact Tom Monaghan at 800-243-5888 or email [email protected].

New Stihl Cut-Off Saw with Water Control SystemThe new Stihl TS 420 A cut-off saw comes with an electronic water control (EWC) system

for wet-cutting. After starting the 4.4-horsepower cut-off machine, the system can be activated

with the push of a button. The plus and minus buttons allow the operator to regulate water flow

for optimal dust suppression while keeping a hand firmly on the handle of the 22.3-pound saw.

The EWC system can use up to 50 percent less water than conventional systems depending on

the cutting job and operator technique. A memory function stores the last water setting after

the unit is turned off, eliminating the need to readjust the water flow. Water flow stops once the

TS 420 A reaches idle speed and begins again when the throttle is engaged.

The TS 420 A can cut concrete to depths of 4.9 inches at a speed of 9,000 rpm. For more information, visit www.stihlusa.com or call 757-486-9100.

Hilti Introduces New Gas Saw Floor CartThe new Hilti DSH-FSC gas saw floor cart is designed for small

cutting jobs requiring the flexibility of a hand held gas saw and the

precision cut and performance of a larger dedicated floor saw. The

cart is compatible with Hilti DSH 700 and DSH 900 gas saws.

The gas saw floor cart is made of heavy duty steel construction and

is supplied complete with a gravity feed water container that allows

the cart to be portable while still providing the dust suppression

needed to help contractors meet local ordinances or other

requirements. For more information, contact Hilti customer service at 800-879-8000 in the U.S., 800-461-3028 in Canada or visit www.us.hilti.com in the U.S. or www.hilti.ca in Canada.

inspection now offers 3D data collection. The

new 3D unit was debuted at World of Concrete

2011 and is now available. The StructureScan

Mini locates rebar, conduits, post-tension cables

and voids in real time. The unit can reach depths

of up to 16 inches in concrete and features a

laser-positioning system and a 4-wheel drive

survey encoder to help mark targets. The unit

has also been designed to be water resistant

and dust proof (IP-64). The StructureScan

Mini system has a center frequency of 1,600

Bosch Introduces GLL2-40 Cross-Line LaserThe Bosch GLL2-40 is a cross-line laser designed

for all professional interior jobsites up to 30-feet. The

compact unit projects lines independently or together

for various types of building construction leveling

and alignment applications with 0.125-inch accuracy.

Weighing eight-ounces, the GLL2-40

is less than two inches wide and less

than four inches in length and height.

The unit can be used to evenly mark

cutting lines or set accurate core

drilling points. A single button control

allows the selection of horizontal,

vertical, cross line or manual modes

of operation. A leveling system locks

the pendulum when the GLL2-40 is

switched off, allowing all parts of the

unit to be protected during transport.

An over-mold construction coupled with a recessed

window ensure against damage from water and dust. The

unit also includes a detachable floor and magnetic mount

that allows full rotation. The mount is equipped with a

0.25-20-inch or 0.625-11-inch tripod mounting thread

for additional mounting options. For more information, visit www.boschtools.com or call 877-267-2499.

Seal/No Seal Group Supports Research EffortsThe Seal/No Seal Group represents the pavement industry, and its members are

committed to quantifying the long-term effectiveness of joint sealants in concrete

pavement. The group has developed a committed and active member base, willing to

work together to advance the industry, and engaged with key industry associations

including the Concrete Sawing & Drilling Association. The group has established

a website that is used to communicate industry news, committee research findings

and other information in support of the industry.

Other accomplishments for the group include having four state DOTs conduct

evaluations of their existing seal/no seal test sections, partnering with roadway

owners to construct 10 new sealant test sections and hiring the Texas Transportation

Institute to conduct research on the effects of joint sealant condition on moisture

infiltration and erosion potential. The group also worked with Purdue University to

support research efforts to search for the cause for premature joint deterioration.

For more information about the Seal/No Seal Group, call Scott Eilken at 708-728-1895, email [email protected] or visit www.sealnoseal.org.

CSDA Wire SAWing 201 OperAtOr CertiFiCAtiOnNovember 18-19, 2011

The Concrete Sawing & Drilling Association is a nonprofit trade association of contractors, manufacturers, distributors and affiliates from the construction and renovation industry. Membership in CSDA is open to concrete cutting contractors, manufacturers and distributors

of concrete cutting equipment and affiliated companies who provide products and services to the concrete sawing and drilling industry. Founded in 1972, CSda reached the milestone of 500 member companies in 2006.

www.csDA.org concrete openings | 6 1

Concrete Renovation, Inc. began in 1990 as two trucks and two guys—me

being one of the guys—operating out of San Antonio, Texas. I knew that

in order for the business to be truly successful, I was going to have to find

help and learn as much as I could. The first place I thought of was the

Concrete Sawing and Drilling Association. After doing some research on

what CSDA offered in the way of training programs, safety materials

and equipment specifications, I knew this was

the right association for the company. Since

joining the association in 1991, I and several

of my operators have gone through CSDA’s

training and certification classes. Every one of my

operators came back to work more knowledgeable

about what material they were cutting and the

equipment they were using. This really raised the

company’s reputation.

Personally, the best benefit of being a member is attending the quarterly

meetings. I have served on the CSDA Board of Directors and my wife,

Donna, is a current Board member. We are both actively involved in the

association and have been part of several committees. It is with pride that we

can say we have helped improve the safety of contractors in our industry by

being part of CSDA’s safety and training committees. I cannot stress enough

how much knowledge can be gained by simply talking with peers. There is a

vast amount of knowledge out there, and all you have to do is ask questions.

Being a member of CSDA continues to be an important part of our business,

and because the association is always looking to prepare contractors for the

future, I feel it always will be.

director’s Dialogue

Executive Director

Regulations – Fight Them or Make Them Work for You

it seems that almost anywhere you look these days, there is a new

regulation dictating how we should live our lives or run our busi-

nesses. in my early days with csDA, there was much reluctance

on the part of anyone to put in writing anything that detailed how

work was to be done. Avoiding the issue was the status quo in the

early days. this strategy worked for quite some time since sawing and

drilling was such a small segment of the construction industry and

under the radar of most regulating organizations. However, things

have changed and continue to do so at a faster pace than ever before.

Quite some time ago, csDA began to document sawing and

drilling procedures. this began by updating a number of older

standards and specifications. some felt that once this updating

was accomplished, all would be well and the csDA standards &

specifications committee could dissolve. Fortunately, others saw a

future that would require continued work in this area.

csDA embarked on a plan to regularly introduce new standards

and specifications, tolerances and Best practices. today, csDA offers

eight specifications that cover all cutting disciplines, including the

newest area of polishing concrete. three standards cover the blade

application code, bolt together core bits and continuous tubing.

tolerances were developed in conjunction with the international

Association of concrete Drillers and sawers and address tolerances

and limits to sawing and drilling as well as basic parameters for

the equipment.

ten Best practices have also been developed. these documents cover

slurry disposal, maintenance, remote control, ground penetrating radar,

polished concrete floors, green concrete and hi-cycle equipment.

in 2006 csDA began to actively work with osHA through a formal

Alliance. when the idea of forming a working Alliance with osHA was first

introduced, many thought that csDA was crazy to be working with the

“enemy.” However, the working relationship has proved to be excellent

and has produced six Best practices covering highway work zones, silica,

defensive driving, electrical safety, scaffolding and ladders. in addition,

through csDA’s involvement with the Design for safety workgroup, a

toolbox safety talk has been produced on sprains and strains.

csDA also has developed its own library of toolbox safety tips (tsts)

for sawing and drilling contractors to use as part of any company’s safety

program. ninety-four tsts can be used to promote workplace safety and

as references in employee safety meetings.

As csDA gets ready to celebrate its 40th Anniversary, great strides

have been made documenting the practices of the sawing and drilling

industry. this effort will only intensify in the future and the standards and

specifications committee is hard at work on a number of new documents.

the decision by csDA to head down this path many years ago was the

right one for members and the industry. it also had a secondary benefit

of increasing the professionalism of the industry, which has been a great

asset when working with specifiers.

Husqvarna’s new electric wire saw, the CS 10, uses components from the WS 440 HFor the WS 482 HF electric wall saws to create a powerful and flexible saw system for cutting through larger concrete structures.

The ability to use a wire saw and a wall saw interchangeably means increased efficiency and a highly cost-effective system. The CS 10 can be easily coupled to the wall saw’soperating unit, track and power supply so switching between the two saws is quick and easy. The saw unit has the option of mounting on either side of the wall saw track and the wire can be rotated in both directions, making it more flexible. The variable wire speed takes into account wire type and material to be cut, resulting in optimalperformance.

The CS 10 wire saw is easy to maneuver and is controlled by a remote control which allows the operator to operate the machine easier and allows greater freedom to move around the work site. The system can be used for all types of wire saw jobs including foundations, bridges and thick walls.
