T

he 2012 construction season is upon us and demands for bids and projects continue to increase in most areas of the country. Hopefully, you have experienced this in your own market. Competition is fierce, margins are tight and job-specific requirements are more complex.

As subcontractors, we are continually being asked to increase our job-specific scope. Customers are focused on getting the best value for their money and hiring a versatile contractor with a range of skills and services. Nowadays, it is often not enough to perform cutting work in a safe, efficient and professional manner.

To win jobs, contractors have to be a one-stop-shop that can survey, cut, remove and recycle concrete. We also have to be better business owners, engaged in the complex contractual requirements of each project.

We need to better understand operational and financial aspects of our businesses. What steps have you taken lately to add to your services or further educate yourself in successful business practices? CSDA has the expertise and tools you need to succeed, together with a membership that is willing to share information and exchange ideas.

The association continues to provide those in the industry with resources that will help them perform better on the jobsite and in the office. The CSDA Membership Directory and Resource Guide is a great resource for contractors and specifiers alike, and can be found online

through www.csda.org. The association is continually looking to support members with the tools they need to be the “best in class” for professionals in the drilling and sawing industry. I encourage you to read through the Standards, Specifications, Tolerances and Best Practices in the Resource Guide to improve your technical knowledge and learn more about some of the things that can improve or expand your business.

Aside from CSDA’s resources, training classes, certification programs and safety tools, the biggest value of CSDA membership is arguably networking. Meeting with fellow professionals at the quarterly Board and committee meetings and Annual Convention is an excellent way to acquire valuable knowledge. Meetings are open to everyone—members and non-members—so please consider joining us at an upcoming event. This month, members will meet in Atlanta, Georgia before traveling to Chicago, Illinois in September. The last CSDA Board and committee meetings of 2012 will take place in Scottsdale, Arizona in December. In each case, the association has negotiated great hotel room rates so I encourage you to attend and see what other benefits you can receive from being part of this association.

View the calendar in this magazine or visit the CSDA Website for more information about any or all of these meetings. See why CSDA is known as the association of cutting professionals.

CSDA Contractor Gets to

the Point Large Concrete Finger Pier Removed from Texas Ship Channel

“Big John,” a crane with a 500-ton lifting capacity, was used to remove the cut pieces.

6 | J U NE.1 2

CONCRETE

After being hit by a tanker and sustaining irreparable damage, a 500-foot-long, 40-foot-wide concrete finger pier had to be removed. The pier was located at the South Central Cement plant on the Houston Ship Channel in Texas. The pier had been out of use for almost two years while several parties argued over responsibility for its repair. Meanwhile, the damage sustained by the pier was causing it to slowly fall into the channel, which would interfere with passing ships.

Due to the location of the pier and the importance of the Houston Ship Channel, the pier had to be removed as carefully and cleanly as possible.

T

he Houston Ship Channel measures approximately 50 miles long, 530 feet wide and is 45 feet deep. The channel is part of the Port of Houston, one of the busiest seaports in the U.S., and has been in use for over 175 years. It is the shipping route for vessels traveling between the Gulf of Mexico and the city’s shipyards.

Two of the most common items transported through this waterway are grain and petrochemicals—both synonymous with the state of Texas— and several petrochemical refineries are located on its banks.

To remove the 500-foot-long, 40-foot-wide finger pier, the general contractor for the project, Orion Marine Group of Houston, Texas, secured the help of Houston-based CSDA member Holes Incorporated, a contractor with the necessary skills, equipment and manpower to complete such a large job with minimal impact on the surrounding environment.

CASES

The Houston Ship Channel.

“This was a high profile project for us. We enjoy completing projects like this, where we have the opportunity to showcase the unique skills of our operators,” said Kellie Vazquez, vice president of Holes Incorporated and CSDA Board member. “Excavators or wrecking balls were not an option, because the pier owner did not want concrete debris falling into the waterway. We were able to offer a better solution,” Vazquez added.

The plan submitted by Holes had a more subtle and environmentallysensitive approach than traditional demolition methods. The techniques recommended by the contractor included slab sawing and wire sawing, which would split the pier into sections for removal by crane to shore. The pieces would then be broken down and removed from the area to avoid debris falling into the water.

The plan included cutting the pier into ten 40-foot-long sections for removal by a Harbor Service Derrick Barge nicknamed “Big John,” which has a lifting capacity of 500 tons. Holes planned to make ten 20-foot-long slab saw cuts 17 inches deep through the center of the pier slab. Then, wire saw cuts would be made from the outside edges of the pier, where slab thickness increased to 36 inches. Cutting would travel back 10 feet towards the center of the pier where the slab saw cut was made, connecting the cut lines.

Two wire saws would be run in tandem to make the outside cuts and free each section from the pilings under the pier. Given the hardness of aggregate in Texas, the combination of slab saw and wire saw techniques was considered the safest and most efficient method to separate the pier from the pilings. This allowed Big John to lift the pieces with ease.

As each section was cut, they would be brought to land by Big John, where Holes demolition operators would use an excavator fitted a 3,000-pound wrecking ball to break up and haul off the concrete to a local cement yard for recycling.

The layout was performed by Orion Marine Group prior to the start of cutting. Operators began cutting from the end of the pier and worked back inland, cutting 17 inches deep using two 72-horsepower slab saws fitted with

blades up to 42 inches in diameter. A total of 200 feet by 17-inch-deep slab sawing was performed on this project before wire sawing commenced.

In order to begin the process of freeing the ten 40-foot sections of concrete, Big John was moved into position to secure the weight of each concrete section. The crane was connected to the slab using four 12-inch anchor chains attached by Orion Marine Group. Core drill operators made two 3-inch-diameter holes at each end of the slab saw cut to run the diamond wire. A total of 40 holes were drilled on the project to allow for 50-foot lengths of 10-millimeter-diameter (0.4-inch) wire to run through the holes, under the pier and through pulleys. Holes ran two wire saws in tandem to make the cuts on separate areas of the pier deck to speed up the cutting and removal process. Most sections weighed 570,000 pounds and took approximately four hours to cut free from the pier, after which the 500-ton crane carried the section to the shore for demolition. The cutting process was repeated until all ten sections were removed, with one section weighing 640,000 pounds. The team cut and removed two 40-foot sections per day.

There were some restrictions for Holes to contend with during the project. As the jobsite was a busy shipping channel, the cutting contractor was given limited access to the pier while ships were in port at other piers nearby. The availability of Big John was also a factor. The crane is in constant demand all over the Houston Ship Channel, so Holes had to schedule work around the availability of the crane.

Safety is always a top priority on all of Holes Incorporated’s projects.

Standard PPE for Holes includes steel-toed work boots, safety glasses, gloves, hard hat and hearing protection. On this particular project, life vests were also required when employees were working on the barge or under the pier. The team from Holes also had to be aware of dangers from above, as the crane maneuvered close to the work area while rigging was put in place. At the beginning of each work day, a toolbox talk was conducted between Holes employees, Orion employees and the Big John crane operator to ensure everyone understood the plan for the day. Red Cut sections weighed 570,000 to 640,000 pounds. w ww. c o n c re te ope n in gs.com

c o n c r et e o pen i n g s | 9

barricade tape was used around the wire saws to mark the work area and provide an extra level of safety for the other workers on the project.

It took Holes Incorperated just over 20 days over a two month period to complete the cutting and removal of the finger pier at the South Central Cement plant. The contractor used two Husqvarna CS2512 wire saws to cut the pier into ten sections. Operators also used 72-horsepower slab saws from Husqvarna and Diamond Products to make cuts in the center of the pier. In total, Holes Incorporated performed 300 feet of 17-inch-deep slab sawing, made 20 10-foot wire saw cuts through the 36-inch-thick areas of the slab and created 40 holes measuring 3 inches in diameter and 17 inches deep to run the diamond wire. Cut sections of concrete measured 40 feet by 40 feet and weights ranged from 570,000 to 640,000 pounds.

The project was completed on time and within budget, and because of the success of this job the general contractor has provided more work for Holes Incorporated. “While discussions are still happening as to who gets the bill for the damage, removal and possible replacement of the pier, we were glad that we could do our work and make the area safer for ships passing through the channel,� said Lee Aitken, estimator for Holes Incorporated.

CSDA: A Cut Above the Rest for 40 Years

Convention Attendance on the Rise Again for Association’s Milestone Event

An impressive number of industry professionals from all over the world gathered in Maui for the 40th Annual CSDA Convention and Tech Fair. There was much cause for celebration—the association reached 40 years and attendance was up for the second year running.

A packed schedule of events took place at the Sheraton Maui Resort & Spa from March 4-9. The enticing program and 40th anniversary celebrations resulted in a 32% increase in attendance from the 2011 convention.

Included in the large number of attendees were new members, first-time attendees, Past Presidents and delegates from the International Association of Concrete Drillers and Sawers (IACDS). The international association held its 17th Annual General Meeting to coincide with CSDA’s celebrations.

To get everyone in the Aloha spirit, a keynote presentation was given and a traditional Hawaiian ceremony was led by Clifford Nae’ole— cultural advisor for the Kapulua Land Company and President of the Native Hawaiian Tourism and Hospitality Association. Nae’ole’s story of The First Canoe coupled Hawaiian cultural lessons with an individual’s journey and life effort. “Clifford’s presentation was very inspirational and appropriate to our business lives.

CASES

The speed and accuracy of concrete cutting with diamond tools proved to be a strong link in the chain during a recent project in Michigan. In January of 2012, a CSDA member was contracted to saw almost 4,000 linear feet of 1½-inch-wide by 1ž-inch-deep slots in an 8-inch-thick concrete floor for the installation of an innovative chain track system at a horticultural center. Due to the location of the work, the cutting technique and the equipment used had to be clean and green.

A

s greenhouse operations continue to grow in size, distances from the harvest to the processing area have lengthened as well. One company has developed an unmanned, in-floor chain track system to which harvesting carts can be connected and transported from the greenhouse to the processing area.

The chain track is installed in the main aisle of the greenhouse, and carts can be put on the chain track at any point. The system is capable of transporting carts around corners and has the ability to switch tracks for multiple collection points. Tracks as long as 4,931 feet have been installed in some greenhouses.

The chain track system travels the length of the greenhouse.

c o n c ret e o p en i n g s | 1 5

Saws were fitted with six ¼-inch-thick blades to make the 1½-inch-wide slots.

A series of 1¾-inch-deep slots were made throughout the building, then joined to form a loop.

In addition to the slot cutting work, the contractor was also required to saw and remove various sizes of 8-inch-thick concrete cutouts up to 48 inches long by 60 inches wide. This was so the general contractor, FormFlex Horticultural Systems of Ontario, Canada, could install pulleys and motorized equipment for the chain track system. The horticultural center is located in southeast Michigan and grows a large quantity of produce in its greenhouse.

As the work was to be done while the greenhouse remained in operation, it was specified that the equipment used be as environmentally friendly as possible. Vegetable crops grown in greenhouses rely on a clean supply of air to survive, amongst other things, so it was important to avoid a buildup of exhaust emissions and dust in the work area. CSDA Member Ohio Concrete Sawing and Drilling, Inc. of Sylvania, Ohio, had the right type of equipment for this job.

CONCRETE “We have a diesel-powered flat saw fitted with a clean air kit, which is a scrubber that reduces carbon monoxide and hydrocarbons,” said Walt Ciesler, safety director for Ohio Concrete Sawing & Drilling. “This was perfect for the track system slot cutting work. In addition, we planned to cut wet and control slurry with wet vacuums, so this was going to be a green job,” he added.

The slot positions were laid out by the general contractor prior to the cutting team arriving at the jobsite. Operators stacked six 20-inch-diameter, ¼-inch-thick blades side by side on a 66-horsepower, diesel-powered Husqvarna FS6600D flat saw to create the required 1½-inch-wide slots for the job. A custom blade collar was engineered to hold the blades. As operators created the 1¾-inch-deep slots in the 8-inch-thick slab, it was important to maintain a straight line and vacuum all slurry generated.

The slots had to be accurate to accommodate the chain track system. The route of the track included two parallel lines that would run the length of the greenhouse and connect when they met in a processing room measuring 80 feet by 150 feet. It took six operators to complete all slot cutting for the job. The overall speed of the work had to be slowed to make

took great care to prevent slurry or dust from being sprayed to other adjacent areas of the greenhouse. Sheets of 4-foot-long, 8-foot-tall plywood were placed on either side of the cutting area to prevent slurry spray from landing on vegetation. There were no special safety concerns for the job, however the cutting team was equipped with all standard items of personal protective equipment needed to finish the job safely.

During 14 days of cutting at the horticultural center, operators from Ohio Concrete Sawing & Drilling cut 3,937 linear feet of concrete to a depth of 1¾ inches. In addition, 7,616 pounds of concrete were cut and removed from the 8-inch-thick slab. The team worked eight-hour shifts to complete the job on time and within budget.

What is Powering Your Electrical Equipment?

By Mike Grisez

T

here are numerous types of electrical equipment used by sawing and drilling contractors every day. The aim of this article is to provide these contractors with knowledge to better understand their options when selecting and powering these machines.

Types of Equipment

Core drill motors are typically electric. Large or extensive coring jobs may require hydraulic power, but electric motors are more commonly used in typical coring applications. Electric core drill motors are available in different specifications, including single-phase brush motors in both 115-volt and 230-volt power and three-phase induction drill motors that are 230 volts or 460 volts for larger diameter coring or deep-hole drilling.

Electric walk-behind concrete saws have a very wide range of power ratings, from 1½ horsepower to 50 horsepower, and are also grouped in single- and three-phase categories. Please note that: • Single-phase, 115-volt motor options range from 1½ horsepower to 2½ horsepower, while 230-volt motor options are available from 5 horsepower to 7½ horsepower.

• Single phase, low-horsepower motors should only be used for light duty production.

• Three-phase saws range from 5 horsepower to 50 horsepower with a supply voltage of 230 volts and 460 volts.

Certain models are also offered as dual voltage configurations, such as three-phase 230/460-volt models that utilize a voltage change switch.

These models can be used on either voltage with a simple flip of a switch and the twist of an overload dial. Always refer to the manufacturer’s instructions for exact details. Having the versatility of both voltage options can save time, money and aggravation when arriving at a new jobsite.

Hydraulic power units that power your hydraulic tools are also available in electric models. These units range from 15 horsepower to 50 horsepower and are only available in three-phase 230-volt and 460-volt power. Voltage change switches are also available for most models.

Electric wall saws primarily use hi-cycle motors. Hi-cycle motors provide added torque and are small in size and weight compared to conventional motors rated at the same horsepower. Power for hi-cycle equipment is more complicated due to the use of higher frequency. A generator can be chosen that matches the frequency requirements of the motor—400 hertz, for example—or an inverter can be used that requires standard 230-volt or 460-volt, 60-hertz, three-phase power.

Power Source The source and size of electrical power is critical when determining what piece of equipment should be used for a cutting job. Two options for power supply and power source are “house power” and “generator power.” When choosing house power, it is necessary to have the proper size breaker. This can be determined at the panel. The breaker should be 125 percent of the Full Load Amp (FLA) of the motor. For example, a 40-horsepower, 460-volt, three-phase motor will have an FLA of 48 amps (48 x 1.25 = 60 amp breaker). When choosing a generator, contractors need to be sure they have the correct size FLA for the motor while taking into account the initial inrush current, measured in amps, during startup.

Generators have different ratings—kilowatt (KW) and kilovolt ampere (KVA). These formulas will also help determine what true power is sufficient when starting and running equipment: KVA vs. KW = KW and KVA differ depending on the Power Factor (PF).

Equation to convert KVA and KW = (KVA x 0.8 = KW) or (KW / 0.8 = KVA) KVA = apparent power Equation for KVA single phase = Volts x Amps / 1,000 Equation for KVA three phase = Volts x Amps x 1.73 / 1,000 KW – actual power producing the work Equation for KW single-phase = Volts x Amps x PF / 1,000 Equation for KW three-phase = Volts x Amps x PF x 1.73 / 1,000 All electric motors require large amounts of electric power to start up for approximately ¾ to 1½ seconds. A generator must be sized to handle the load of the starting winding. The chart in Figure 1 determines a motor code letter that is found on all motor nameplates. This allows for the calculation of starting amps, better known as locked rotor amps (LRA).

Single-Phase Motor Starting LRA The formula is: motor horsepower (HP) x KVA per HP x (1,000 / motor voltage) = LRA. As an example, a ¾ HP, Code L motor connected to 240 volts requires 31 LRA. This is calculated by referring to Figure 1, finding Code L and using the largest KVA/HP number—in this case 9.9. The formula becomes: 0.75 x 9.9 x (1,000/240) = 7.425x4.167 = 30.9 = 31 LRA. The generator must produce 31 amps at 240 volts to safely start this motor.

Three-Phase Motor Starting LRA The formula is: motor HP x KVA per HP x (1,000 / (Volts x 1.73)) = LRA. Therefore, a 20 HP Code G motor connected to 460 volts requires 159 LRA. This can be confirmed by first referring to Figure 1 and selecting 6.29 KVA/HP for Code G. Then the formula becomes: 20 x 6.29 x (1,000 / (460 x 1.73)) = 125.8 x 1.26 = 158.5 = 159 LRA. The generator must produce 159 amps at 460 volts to safely start the motor.

Electrical soft starters can be any control system that reduces the torque by temporarily reducing the voltage or current input. This can also be a device that temporarily alters how the motor is connected in the electric circuit (Delta/Wye).

By using a soft start system, the size of generator required for startup will be reduced (see Figure 2).

TECH TALK Other Common Factors to Take Into Consideration Power Cord Selecting a power cord is a two-step process: Step 1—Based on the amps required for the equipment and the length of cord needed, the information in Figure 3 can help find what American Wire Gauge (AWG) rated wires are needed in the cord.

Step 2—Determine what cord construction is needed (hard service or water resistant, for example).

A contractor can experience problems if the correct cord gauge has not been chosen. As the voltage drops the amperage will go up, causing excess heat to build up in the windings of the motor. The internal windings of a motor are insulated for certain temperatures that the motor is designed to work in.

When these temperatures are exceeded, damage to the motor occurs. This can take a while under slight conditions and happen quickly under adverse conditions.

What are Power Boosters (AKA Buck-Boost Transformers)?

A Buck-Boost Transformer is a small two-winding transformer used to increase or decrease the supply voltage by a small amount. For example, it may be used to increase the voltage from 208 volts to 240 volts.

These are just some of the many important details when determining what power to use for electrical equipment and how to use it. Electrical construction equipment is not just “plug and play” machinery. The devil is in the detail, and having the correct knowledge to make educated choices

Down to the Concrete Bridges Cut and Removed in Mexico Two reinforced concrete bridges with a combined volume of 4,053 cubic meters (143,130 cubic feet) were to be removed to make way for the construction of a new liquid natural gas storage and regasification terminal in Manzanillo, Mexico. Over a three-month period, a specialist cutting contractor used diamond wire sawing techniques to remove the bridges and keep the project on time.

2 4 | J U NE.1 2

Wire T

he bridge demolition work was part of a larger project to construct the Manzanillo Liquid Natural Gas Storage and Regasification Terminal on the east coast of the country.

Several companies worked on site to make sure the terminal opened in July 2011, as planned. Other work included the construction of a regasification terminal, a new port for deep-water tankers, new paths for rail and road links and breakwater areas. In addition, part of the nearby Cuyutlan Lagoon had to be dredged to make the terminal accessible to large tankers. The new terminal now supplies liquid natural gas to the power plant. The regasification plant then turns the liquid back into gas. The plant has two storage tanks that can hold 500 million cubic feet of gas daily and can generate 1,800 megawatts of electricity.

Mexico’s Secretariat of Communication and Transportation contracted Coconal S.A. for the infrastructure work at the terminal, which included the demolition of the Malecon railroad bridge and the Mirador road bridge. The Malecon bridge measured almost 153 meters long (502 feet) and consisted of 1,960 cubic meters (69,216.7 cubic feet) of reinforced concrete, while the Mirador bridge was 150 meters long (492.1 feet) and was made up of 2,093 cubic meters (73,913.6 cubic feet) of concrete. Both bridges had to be removed to allow deep-water tankers to arrive at the new terminal. The contract for the demolition of the bridges alone was the equivalent of US $6.6 million. The demolition and removal of the structures required a specialist contractor to complete the work, so Coconal contracted CSDA member Soluciones TÊcnicas y Profesionales ADRA S.A. de C.V. (ADRA) of Leon, Mexico.

Opposite: Each of the two bridges cut and removed measured around 150 meters long (492.1 feet).

“This represents an enormous step for Mexico in sustainable development and the fight to hold off global warming. The change from fuel oil to natural gas will save 1 to 1.5 million tons of coal being burned and pumped into the atmosphere every year,” said Raul Bracamontes, owner of ADRA. “A large gas cloud has become a common sight for the people of Manzanillo. The opening of the natural gas terminal will cause the gas cloud to disperse and the air quality in the area will improve immeasurably,” he added.

The Cuyutlan Lagoon, which is situated close to the jobsite, is considered an ecological reserve, so the contractor was required to remove the bridges with an absolute minimal amount of debris. The only method that would insure against excessive noise, vibration and debris was wire sawing. A plan was drawn up to cut the bridges into large pieces so they could be lowered to the ground by crane before being demolished by hydraulic hammers on the shore.

The close proximity of local traffic and utility piping represented further challenges for the team from ADRA. The Mirador road bridge was to remain open during part of the work, so the contractor would have to consider closing and removing just one lane of the bridge at a time, while traffic continued to travel over the bridge in the other. Maintaining the structural integrity of the bridge was the top priority. In addition, both bridges had pipes running close to them—one of which supplied 60 percent of Manzanillo’s water. Cutting had to be carefully planned to avoid damaging these pipes, which would be shut off and removed before the final phase of the demolition work.

Work began in January 2011 with the demolition of the Malecon railroad bridge. The 153-meter-long (502-foot) post-tensioned concrete structure was made up of two concrete beams joined by a ½-meter-thick (1.6-foot) slab. The slab was built in five sections each measuring 30 meters long (98.4 feet). Six reinforced cylindrical pillars supported the structure. Each pillar was 15 meters tall (49.2 feet) and 4.5 meters (14.8 feet) in diameter. The pillars, along with a pipeline that ran parallel to the bridge, were enclosed under the structure by two 0.8-meter-thick (2.6-foot) reinforced concrete walls.

First, a temporary new railroad bridge was built a few meters from the existing one to allow rail transport operations to continue. Once the bridge was cleared of tracks and other fixtures, it was necessary for the general contractor to construct an embankment next to it. This embankment provided ADRA with a location to position a power pack and water tanks for the cutting work, and allowed cranes to be maneuvered into a good position for lowering the concrete section when cut. The embankment was formed on top of a 36-inchdiameter steel pipe that allowed water ingress to the lagoon.

The contractor then marked out the cut areas in preparation for wire saw setup. The cuts had to be in accordance with the capabilities of the cranes on site, so operators split each of the five bridge sections into three 170-ton pieces. Two longitudinal cuts were made on each section, each measuring 30 meters long (98.4 feet). Operators made 2½-centimeter-diameter (1-inch) holes using a a hammer drill for the diamond wire runs, and made two further holes to pass steel rigging through for lowering by crane.

As each concrete section was cut free from the bridge structure, the cranes lowered the pieces to ground a safe distance from the work where they were demolished by hydraulic hammers. Reinforcing steel was separated from the concrete before all waste materials were removed from site for disposal. To remove the six foundation pillars in their entirety, it was necessary for ADRA to dredge the surrounding area to expose more of the pillars. Operators then made 20.3-centimeter-diameter (8-inch) holes through each pillar for rigging.

The two 400-ton cranes then removed the pieces for demolition.

The team from ADRA then turned its attention to Mirador Bridge. This road bridge consisted of six AASHTO type IV beams with five 30-meterlong (98.4-foot) sections of 20-centimeter-thick (7.9-inch) reinforced concrete slab, supported by six pillars 61 centimeters (24 inches) in diameter and 12 meters tall (39.4 feet). A pipe ran under the bridge supplying water to the surrounding area, so cutting and removal of the structure had to be precise. As per the Malecon Bridge work, an embankment was formed next to the Mirador Bridge by the general contractor to place equipment and position cranes.

As the bridge was to remain in operation for part of the work, operators began cutting selective parts of the substructure first. Cutting commenced with the two 30-meter-long (98.4-foot) longitudinal cuts on each segment, before one longitudinal cut was made. Operators then set up to cut the substructures. The wire saw made two cuts on the header of each substructure. The team returned to the top side of the bridge to cut between the beams, making two cuts per bridge section. ADRA made 10-meter-long (32.8-foot) cuts on the bridge slab and completed an average of two cuts per day. It took around 14 hours to cut each substructure of the bridge, and about two hours to cut the substructure free from each pillar.

To complete the work on time, ADRA employed five operators to set up and execute the specified cuts. Coconal supplied laborers and crane operators to perform dredging, crane operation and cleanup. Cutting operators worked alternate eightPillars measured 61 centimeters (24 inches) in diameter and were removed by crane. hour shifts to maintain progress.

The Business of Business

Understanding How Business Owners Act and Think

By Les Cunningham

B

usiness owners are a very unique type of individual, whose plans and actions can often be misinterpreted by employees. In many cases, this is neither the fault of the employee or the owner alone, but rather a simple case of miscommunication. It helps to know exactly what motivates owners and what visions they have for their businesses. By having a clearer understanding of each other, business owners and employees in the concrete sawing and drilling industry can work towards a common goal—success.

Here is a list of ten owner attributes that employees may often misconstrue, together with possible explanations as to why owners display such attributes.

“My boss is so stressed out.”

Owners have a strong internal drive to see their burning idea succeed. They believe their idea is so hot and pressing that they want to see it become a success. It is a personal issue for them. An owner may feel that if they do not make the idea work, it is a poor reflection on them and their abilities as a person. They are motivated on a personal level to achieve the absolute best they can with their business.

“They are always worried.”

Owners are fear driven. In fact, it is likely their most powerful drive. It motivates them in all phases of their efforts. Some feel that their whole life revolves around the company.

The company being successful translates to the owner feeling successful. As a result, an owner’s moods will move up and down as the company’s success, or lack thereof, fluctuates.

However, this drive often creates focus and can lead to success.

“It seems they are not confident in the success of a job.”

Owners have an internal voice that is actively questioning anything and everything that they do. This incessant voice constantly

2 8 | J U NE.1 2

“They are always checking up on me.”

Owners are constantly checking on their people, sometimes consciously and sometimes unconsciously. As a result, employees have the misconception that their employers do not trust them. It is natural for business owners to be curious about all aspects of their company.

In some cases there may be a trust issue, but often the owner is happy for employees to take ownership of jobs while they stay in the background for support.

“My boss is giving my job responsibilities to someone else.” raises doubt as to whether or not it is the best effort they can produce with the time and resources at their disposal. It often leaves the owner feeling that they should have chosen differently, even if success has been achieved.

“The boss doesn’t trust me.”

Owners want to trust their people, but also worry whether their employees will do the right thing. They can be apprehensive about trusting their employees and have concerns things may be turned upside down without their supervision. As an owner, there can be a feeling that irreversible damage can be done unless they are actively involved in all things. This is a business they have built up themselves over a period of time, so it can be hard to step back and share the responsibility.

“We are always changing our procedures and the way we do things.”

Owners are constantly changing things, but this is often for good reasons. They feel that by regularly reviewing their efforts, and those of their employees, the company can do things better. The interesting part is that owners are constantly reviewing everything around them. It may be frustrating for an employee, but changes are often necessary to maintain success or improve upon it.

Owners have a tendency to give more than one person the same job. This can be for a number of reasons, but the problem occurs when employees are not made aware their job now also belongs to someone else. When the employees realize this, and the inevitable collision occurs, the team members are often left feeling used, hurt, distrusted or worse—inadequate. Business owners like to hedge their bets by making sure more than one person is knowledgeable and responsible for a given job, should one of these people not be available for any reason. Successful business owners will communicate this with their employees to avoid confusion or conflict.

“I am not given the opportunity to finish the job I started.”

Owners may take over a task they have previously delegated to someone else, worried it is not being done exactly as they would do it. The owner feels a sense of urgency to get involved, often preemptively, without giving adequate time and responsibility to the employee. The owner wants to make sure that the task is done correctly and in the time frame they have set with the customer. It is important for owners to be confident in the skills of their trained and experienced employees, as often they will get the job done just as well.

“I am flooded with emails and phone calls from my employer.”

The owner may feel they are not getting all of the information they need to know. As a result, they are constantly asking questions of anything and everything that is going on in the company. A lot of employees feel that this questioning is a reflection on how they are performing. An owner must have feedback from employees or supervisors to maintain control over operations. It is a given that if the owner does not receive the required information in the time frame specified, they will seek it out. Having this realization allows both owners and employees to determine a set procedure to get the desired information to the right person. Owners must always remember to clearly communicate expectations, then the people tasked with meeting these expectations can work more efficiently to the goals set.

What sometimes happens is that owners are not aware, or maybe even unwilling, to clearly communicate what they expect and need.

So what actions should an owner or an employee take as a result of the ten observations listed above? The first thing is to understand that communication is a key factor in the success of any business. Improved communication between the business owner and employee will create a better work environment and build a trust. Allowing an open dialogue will provide both parties with the opportunity to exchange ideas, set realistic targets and communicate any foreseeable problems with the job. It is also the time to set in place procedures that maintain good communication during all phases of the job. This will help to eliminate any fears or doubts held by the owner and give the employee confidence that they are not having their work scrutinized.

It can be hard for either side to take the first step to improve communication, but this

Owners have an internal time clock on everything they do. It drives them in ways they do not even recognize and their experiences help determine time frames for jobs and other tasks. However, these time frames and expectations need be communicated to their employees with clarity and accuracy. If not, owners may feel they have clearly communicated their desired schedules while their employees may have a different understanding and set different priorities. When this disconnect occurs, owners can feel as though their fears about an employee are validated, building distrust and concern.

crucial step is best taken by the leader of the company. Once the owner establishes a channel of communication with employees, the likelihood is that the employees will actively work at improving the communication loop and a good working relationship based on trust will result.

All this adds to the success of the company, the ultimate goal for any business owner.

CORE HEALTH

It’s a Long, Hot Summer–Treating Heat Illness

By Erin O’Brien

T

he summer months are quickly approaching, although some of us have been feeling the heat for quite some time. The intensity and length of the summer months vary in different parts of the United States and throughout the world, but one factor remains constant–heat. No matter how long an area’s summer is, chances are, it will be hot, sunny and possibly humid. All of these factors combine to create dangerous working conditions for sawing and drilling contractors working in an outside environment.

Heat illness can be a life-threatening condition, especially if not treated properly. It is brought on by many variables, including, but not limited to, high temperatures, high humidity, sun and dehydration. Because heat illness can quickly turn from a mild condition that can be easily treated to a life-threatening condition, it is important for all sawing and drilling contractors to be aware of the signs of heat illness and how to properly treat it.

As always, the best treatment is prevention. It is also important to recognize the signs and symptoms of heat illness, as well as the various stages (Figure 1). Once heat illness has progressed to the stage of heat exhaustion an immediate response and possible emergency transport, may be necessary. The following section details how to best treat each stage of heat illness.

Heat Syncope: Heat syncope, or heat collapse, is usually associated with rapid physical fatigue during overexposure to heat.

Workers who have been outside in the heat for several hours, or workers who are not accus-

tomed to extreme heat, are susceptible. Heat syncope can be treated quickly and effectively by having the worker lie down in the shade or a cool environment and having them drink cool fluids. Water or sports drinks are recommended.

Heat Cramps: Heat cramps are extremely painful muscle spasms that occur predominantly in the calf and abdomen, but can occur in any muscle in the body. Heat cramps are usually brought on by dehydration and the associated loss of electrolytes and minerals in the body. A worker experiencing heat cramps should immediately ingest a large amount of water or sports drink and stretch the affected muscle. If possible, ice should be applied to the muscle to reduce pain and the likelihood

of heat cramps reoccurring. The worker should rest for as long as possible, as reoccurrence of heat cramps is likely.

Heat Exhaustion: Heat exhaustion results from inadequate replacement of fluids lost through sweating. Workers may develop heat exhaustion if heat cramps are not treated properly. Workers who are in poor physical condition and exposed to long periods of heat are more likely to develop heat exhaustion. Any worker who is, or recently has been ill is more likely to develop heat exhaustion. Immediate treatment is required, and consists of large quantities of water and cooling the body down immediately.

Fluid replacement is primary, and the worker should be moved to a cool, shaded location. If the worker does not show improvement within several minutes, they should be taken to the hospital for further evaluation and treatment.

It is not recommended for a worker who has experienced heat exhaustion to return to any job in a warm environment for the remainder of the day.

Heatstroke: Unlike heat syncope, heat cramps and heat exhaustion, heatstroke is a serious, life-threatening emergency. It can occur suddenly and without warning. A worker will not usually experience or admit to any signs of heat cramps or heat exhaustion. The possibility of death from heatstroke can be significantly reduced if body temperature is lowered to normal (98.6°F/37°C) within 45 minutes. The longer the body temperature is elevated above 104°F, the higher the mortality rate. The most important thing to do for the worker is to lower body temperature dramatically and immediately. Remove them from the hot environment, or at least the sun, and quickly use cool towels, fans and shade to bring down the body temperature. Transport the worker to the hospital as quickly as possible, whether it is by ambulance, work truck or private vehicle. Fluid replacement is not important in this case, the most important thing is to cool the worker down immediately and emergency transport to the hospital.

Again, remember that the best treatment is prevention. All workers should be properly hydrated while on the job as well as before and after they are at work. The type of hydration is important as well. Water and sports drinks are the best choices. Anything with caffeine (coffee, soda or energy drinks) or high levels of sugar (fruit juice, sweet tea or soda) should be avoided. Energy drinks (Red Bull, Rockstar, Monster and AMP, for example) can be especially dangerous, as these not only will dehydrate a worker but also increase their heart rate, making them more susceptible to heat illness. A perfectly healthy worker who is physically active and acclimated to the heat can easily develop heat illness after ingesting an energy drink.

All concrete sawing and drilling workers should be aware of the signs and symptoms of the different types of heat illness, and be aware of the most effective treatment for each. Older and less physically active workers are especially at risk. Keeping an eye on fellow workers during the long, hot days of summer will help keep everyone safe and able to effectively deal with the heat.

2012 IACDS Annual General Meeting International Association Meets in Maui to be Part of CSDA’s Celebrations

T

he 17th Annual General Meeting of the International Association of Concrete Drillers and Sawers (IACDS) was held on March 6.

The meeting brought together delegates from all over the world to discuss the global status of the sawing and drilling industry, make plans for the future and join CSDA’s 40th Anniversary celebrations.

Representatives from Austria, Belgium, Germany, Japan, Liechtenstein, Spain, Sweden, Switzerland, the United Kingdom and the United States attended the meeting, and were given two presentations relevant

to today’s industry. Andrey Kossolapov of the Moscow State Civil Engineering University gave a presentation entitled A Method of Time Calculation in Concrete Sawing. A first for IACDS, the presentation was made via Skype.

Delegates listened and watched Kossolapov via video link as he gave his presentation from his home country of Russia. Using the correct calculations to determine time and resources on a sawing and drilling job can save contractors money, and display a high level of competency to general contractors and other specifiers of concrete cutting methods. The delegates discussed the formulas and calculations presented to them, and were in agreement that they could be of great use to contractors— providing they were properly taught.

IACDS members were then given a presentation by Matt Dragon and Paul Fowler of CSDA member Geophysical Survey Systems, Inc. (GSSI) on The Benefits of Ground Penetrating Radar (GPR) Technology. The method of GPR scanning is widely used in some countries while seldom used—or heard of—in others, so this was a good opportunity to explain the use of this relatively new technology to an international audience. The addition of GPR scanning can provide cutting contractors with an opportunity to increase revenue by offering this service in conjunction with cutting work on job bids. Delegates learned how the technology works to detect hidden objects like pipes, ductwork and post-tensioned cables, and were given a live demonstration of a typical GPR grid scan.

Besides the presentations, current IACDS president, Jose Blanco of Spain’s Association of Technical Demolition Cutting & Drilling, gave his annual report to the attendees and discussions were held on the association’s planned activities for the coming year. The main talking point was the 2013 Diamond Award ceremony (see sidebar), which will coincide with a series of industry-related seminars organized by IACDS at the Bauma 2013 exhibition and trade show.

This international trade show is scheduled for April 15-21, 2013 in Munich, Germany, which will also be the location for the 18th Annual General Meeting of the association.

Delegates from each national association then gave a brief report on the health of their markets, which largely remained unchanged from the 2011 meeting. The sawing and drilling industries of Japan, Spain, the U.K. and the U.S. are now showing some positive signs, but it may be some time before these markets return to where they were before 2008. Meanwhile, representatives of the Austrian, German, Swiss and Swedish associations continue to see growth in their industries and membership levels remain strong.

Blanco will continue as president of the international association, fulfilling his two-year term, while Norikazu Shibuya of Japan and Lars Sandstrom of Sweden remain as vice presidents until the 2013 election. The next IACDS annual meeting will be held in Munich, Germany on April 22, 2013 after the Bauma show.

CASES

Sawing and drilling contractors are often given warnings of potential jobsite dangers. However, one cutter was given a very unusual warning on a recent job—don’t disturb the sharks!

T

he National Marine Aquarium in Plymouth, England, is linked to a registered charity that promotes an understanding of the sea through programs of education, conservation and research.

Opened in 1998, it is the largest public aquarium in the United Kingdom and one of the most popular attractions in the region—attracting more than 260,000 visitors every year. The aquarium has over 4,000 marine animals and the main tank is the deepest of its kind in the country. The aquarium also has a state-of-the-art learning center.

The aquarium was to be expanded and renovated to incorporate new exhibits and attractions. Concrete cutters were called in to cut and remove an 8-meter-long (26.2-foot), 1-meter-tall (3.3-foot) and 500-millimeterthick (19.7-inch) solid masonry wall beneath the aquarium’s main exhibit tank. The tank measures 14 meters (45.9 feet) wide, is 24 meters (78.7 feet) at its longest point and has a maximum depth of 10½ meters (34½ feet). It holds several different species of shark, including tiger sharks, together with other marine life. The plan was to install a new nursery tank and viewing area where the wall stood.

With marine life in close proximity, the customer requested that the contractor work as quietly as possible. Excessive noise and vibration would cause distress to the animals and may have resulted in them injuring each other. A technique was needed that would produce less noise and lower vibration levels than those associated with traditional demolition methods. CSDA member D-Drill Master Drillers Ltd. of Coventry, England, was contracted to do the work. This contractor proposed to use diamond tools to cut the wall into uniform pieces and easily remove them from the building with minimal disruption and debris.

Edward Taylor, manager of D-Drill’s Plymouth office, said, “Normally we would use a drill or breaker to remove the wall but, because we had been asked not to disturb the sharks and other animals in the tank, we looked for the best possible alternative. Nobody wants to upset a shark, even if it is inside a tank!” The contractor chose to use hand sawing techniques to get the job done. The plan was to cut the wall into several small pieces before transferring to a truck for disposal. Cutting work would start toward the end of March 2012, so that the rest of the quieter renovation work could be done over the following weeks. The Easter holiday period brings many visitors to the aquarium while children are out of school, so it was important to complete demolition work before lots of people filled adjacent rooms and viewing areas.

The National Marine Aquarium in Plymouth, England, is the largest public aquarium in the U.K.

Before cutting work commenced, the room where the wall stood was cleared and all fixtures, fittings and any remaining elements of the aquarium’s exhibits were protected with plywood and acrylic sheets. This included cameras that were in place to film the entire renovation and expansion of the area. The team from D-Drill then set up water control measures using a wet vacuum to collect waste water and slurry. A hydraulic power pack was supplied to run the hand sawing equipment and was situated outside of the room to keep noise to a minimum.

The operator used a 17½-horsepower 880F4 hydraulic chain saw from ICS to make the cuts. The 1-meter-tall (3.3-foot) and 8-meter-long (26.3-foot) wall was marked out into 32 500-millimeter (19.7-inch) square

sections for cutting. First, 15 vertical cuts were made at regular intervals down the full height of the wall. It took approximately 10 minutes to make one vertical cut, taking around three hours to cut and remove the entire wall as specified. All cut sections were placed into a truck ready for transport to a disposal facility.

In addition to the limitation of noise and vibration specified by the aquarium owners, the team from D-Drill had to adhere to other guidelines and precautions to guard against injury to the operator or other personnel on the jobsite. All of the contractor’s employees are supplied with items of personal protective equipment like hard hats, eye and ear protection, gloves and high-visibility vests. The operator was well trained in the safety, operation and maintenance of the concrete chain saw before work started. The indoor work area was restricted to contractor employees only. This was to avoid aquarium employees or visitors being exposed to any dust or debris formed by cutting the wall, and to keep them safe from potential trip hazards as hydraulic cables ran through the room.

An operator made 15 vertical cuts down 1-meter (3.3 feet) height of the wall before splitting the sections into 32 500-millimeter (17.3-inch) square pieces.

A 17½-horsepower hydraulic chain saw was used to make the cuts.

The low noise and vibration produced by diamond chain sawing caused minimal disruption to the inhabitants of the aquarium.

D-Drill Master Drillers used the ICS chain saw to make all the required cuts. The saw was powered by a hydraulic power pack, also from ICS. A submersible pump and wet vacuum were used for water supply and waste containment respectively. It took one operator and one laborer eight hours to cut and remove the masonry wall at the National Marine Aquarium. The job was completed on time, within budget and with minimal disruption to the aquarium and its residents.

“D-Drill was extremely professional, fully understood the issue and went out of their way to ensure they completed the job with absolutely no disturbance to any of the sharks and other animals in the tank,” said James Wright, assistant curator at the aquarium. “The sharks normally swim quite slowly and appear sluggish, but when they go they certainly move quickly. When they do, they can collide with each other or objects in the exhibit, causing injury,” he added.

Thanks to the versatility of diamond tools, this contractor was able to complete quite a sensitive job with ease. In their natural habitat, sharks are a real force to be reckoned with. The same could be said for concrete cutters when on the jobsite. The work was completed over two days in March and the aquarium’s new exhibit and viewing area is scheduled to open in the summer of 2012.

Safety CountS

Fall Hazards: One of OSHA’s “Big Three”

By Mark A. Lies II and Elizabeth Leifel Ash tive equipment. Personal fall arrest systems are considered personal protective equipment; therefore, employers are required to evaluate the workplace to identify potential fall hazards and to provide and require the use of appropriate protective equipment to protect employees from those hazards. This regulation also requires employers to certify that this assessment has been done and that the fall protection equipment has been provided.

OSHA’s Construction standards (Part 1926) contain more consolidated fall protection requirements. For example, Section 1926.501 requires employers to provide fall protection equipment for any employee walking or working more than 6 feet above the lower level.

Whether OSHA’s General Industry or Construction standards apply depends on the type of activities employees are engaged in. The lines between General Industry and Construction activities often blur in industries where employees perform some activities that fall within the “construction” category and some activities that fall within “general industry” categories, such as the outdoor advertising (billboard) industry or building inspectors who enter construction areas to conduct inspections. Thus, careful scrutiny of which category of standards applies is necessary for any employer to determine its obligations with respect to fall protection.

Introduction

I

n 2010, the Bureau of Labor Statistics (BLS) reported that fatal work injuries involving falls decreased 2% in 2010 (from 645 in 2009 to 635 in 2010), although each one of these incidents is a human tragedy. Fortunately, since 2007, fatal falls in the private construction industry have decreased by 42%. Despite this decrease in fatalities, OSHA’s fall protection standards continue to be among the leading bases for citations against employers. In fact, in 2011 OSHA’s construction fall protection and related scaffolding standards were the top two most frequently cited standards.

Fall protection requirements can be found in multiple locations throughout OSHA’s standards, particularly for general industry (Part 1910). The application or potential application of several different standards can make it difficult for employers to determine their fall protection obligations. This article outlines the various OSHA standards that contain fall protection requirements and recommends proactive measures for employers to identify and prevent fall hazards.

Legal Framework Fall protection requirements apply in a large variety of situations, including working on top of large tanks or other equipment, working on top of tractor trailers, using fixed or portable stairways and working on rooftops (with or without a pitch). The general term “fall protection” involves more than just preventing personnel from falling, but also includes preventing tools and other equipment from falling from elevated surfaces onto employees walking or working below.

In general, OSHA requires some form of fall protection equipment for any walking or working surface that is elevated 4 feet or more. Such fall protection equipment generally refers to guardrails (including mid-rails and toe boards) or other fixed barriers that physi-

4 2 | J U NE.1 2

Recent Developments

cally prevent an employee from falling. Fall protection can also refer to personal fall arrest systems, such as harnesses and lanyards, which will stop an employee from falling more than a specified distance.

Section 1910.132 places a general obligation on employers to identify hazards in the workplace that may require personal protec-

OSHA continues to aggressively enforce fall protection requirements through issuing citations to employers who violate any one or a combination of the standards listed above.

For example, OSHA recently issued a roofing company in Massachusetts ten Serious citations related to employees working on a ladder jack scaffold atop the roof of a building in Boston. The citations amounted to $42,000 in civil penalties.

employees to work at elevated heights and should take all reasonable measures to ensure that employees are protected while working on elevated surfaces. Along these lines, employers should develop a strategy for dealing with fall hazards.

• Employers should evaluate the workplace to identify elevated areas that may require guardrails or other protective equipment.

Similarly, OSHA has recently cited multiple employers around the country in connection with tragic falls through building skylights.

Employees who are not in the roofing industry, but who venture onto a roof to check HVAC systems or make other repairs to the roofing system, may not be as aware of fall hazards like skylights or vents. In February 2011, OSHA cited Ryder Transportation Services and its outside electrical contractor for violating the general industry standard, 29 CFR §1910.23(a) (4), after an electrician died on Ryder’s premises. In 2006, Ryder designated the rooftop of their Doraville, Georgia facility as a “Restricted Area,” forbidding access to Ryder employees.

This demarcation served as an alternative measure ensuring compliance with standing OSHA skylight regulations, as the rooftop skylights had neither a protective screen nor a fixed standard railing on all exposed sides.

Furthermore, the skylights’ design blended in with the surrounding roof camouflaging a perilous 25.8 foot drop to the ground. In order

to repair ventilation fans, however, an outside electrician was granted access to the rooftop without being made aware of the skylight hazards. Sadly, the electrician fell to his death after a skylight collapsed under his weight.

In addition to aggressive enforcement, OSHA has also proposed extensive revisions to the General Industry walking and working surfaces regulations. Although OSHA first proposed these revisions in the 1990s, OSHA reopened the rulemaking docket in 2010 and held multiple public hearings in 2011 in an effort to move forward with the revisions. OSHA has slated October 2012 as a goal for publishing a final rule revising the walking and working surfaces standard.

Conclusion and Recommendations There is no question that OSHA, under Dr. David Michaels, continues to crack down on employers who violate fall protection requirements. Employers should be aware of the potential liability associated with allowing

•

Employers should develop written fall protection work rules that cover any situation involving employees walking or working at heights, including the use of mobile equipment like manlifts and mobile platforms.

•

Employers should ensure that employees are trained to recognize potential fall hazards in the workplace and notify management of any unprotected walking or working surfaces that are elevated greater than 4 feet.

•

Employers should ensure that whenever a personal fall arrest system is required, employees are trained to inspect the equipment for defects before each use, and are trained to store and maintain the equipment properly to prevent damage.

•

Employers should train supervisors to administer disciplinary action against employees who are working at heights without required fall protection equipment.

•

Whenever an outside contractor is brought on site, the host employer should seek the contractor’s assurance that employees are provided with the required fall protection equipment. Otherwise, the host employer may face OSHA liability under the multiemployer worksite doctrine.

Heat is still an occupational concern for all workers on outdoor jobsites. As of April, OSHA began the second year of its Heat Campaign to keep attention focused on this issue and highlight several of the resources available to businesses.

According to the U.S. Bureau of Labor Statistics (BLS), 37 workers died from heat-related illnesses in 2010, and almost 270 workers have died between 2003 through 2010. However, this just the tip of the iceberg. In 2010, for example, BLS recorded that more than 3,400 workers suffered heatrelated injuries and illnesses—a number that is almost double the number (1,790) from the previous year.

The work can’t get done without them.

Almost everyone recognizes that outdoor temperature and humidity can be an issue.

OSHA has focused its campaign on three simple words that can prevent heat illnesses: Water.

Rest. Shade.

To raise awareness and get the “Water. Rest. Shade.” message out during the 2012 Heat Campaign, OSHA Regional and Area Office representatives will reach out to employers and workers by participating in national and local conferences, training sessions and media events.

In addition to the resources available in Spanish—like training guides, QuickCards, fact sheets and posters—two resources, the Heat Index Guidance for Employers and the Heat Safety Tool Smartphone App, have been added. The Guidance outlines the progressive steps that employers can take to protect workers based on the risk levels established using the Heat Index. It also includes technical information on setting work and rest schedules, ensuring workers are acclimatized and planning for emergencies. The Heat Safety Tool App is based on the Guidance and allows a user to automatically get or calculate the Heat Index. It then shows reminders of the precautions that should be used at the established risk level.

Insurance CornER

Predicted Changes in the Market

By Tony Evans

“U.S. commercial insurance rates expected to rise this year: Marsh” —Business Insurance (January 25, 2012) “Commercial lines prices up for 4th straight quarter: survey” —Insurance Journal (March 12, 2012) “P/C insurers’ combined ratio for 2011 estimated at 107.5%” —Insurance Journal (February 6, 2012)

Introduction

T

here are significant changes looming on the horizon for the property and casualty insurance industry. It is expected that most businesses in all industry segments will be affected negatively from a rate or premium perspective. Due to the changing market conditions, property and casualty insurance premiums are starting to increase and will likely increase into the near future. What we do not know right now is how much insurance rates will increase over time and how long the hardening insurance market will last. Most businesses have seen improvements in their financial position recently, but many of these businesses have a long way to go before they get back to the financial position they enjoyed before 2008. Therefore, the last thing businesses need right now is increasing insurance costs.

4 6 | J U NE.1 2

It is important for concrete sawing and drilling contractors, and business owners in general, to understand what these financial indicators mean. The primary issue is directly related to carrier profitability.

Changes Affecting the Market Over the last several years, the profitability of the insurance industry has deteriorated. In 2011, the insurance industry posted a Combined Ratio of 107½%. This means that for every $1 the insurance companies are taking in as premium, they are paying out about $1.08. The insurance companies also have the benefit of investment income to help reduce the $1.08. However, due to historically low interest rates, these insurance companies are not making enough investment income to make up the gap. Therefore, most carriers are in a position where they must increase insurance rates to improve profitability.

There are other factors that play a role in a changing insurance market, but this is the basic premise that drives the trend. Also, the 107½% number is a blended ratio across all lines of insurance coverage. Some carriers have Combined Ratio numbers for Workers’ Compensation insurance nearing 120%, which puts this line of coverage in a critical position.

Additionally, 2011 was one of the worst catastrophe years on record, so property insurance rates will see an accelerated increase similar to Workers’ Compensation. Those companies exposed to windstorm or earthquake exposures will certainly experience such an increase.

Other lines of coverage will likely increase; however, Workers’ Compensation and property will be the leaders.

Another, lesser known change will likely affect the Workers’ Compensation experience modification factor for many in the sawing and drilling industry. In 2013, the National Council

on Compensation Insurance (NCCI) will be changing the way it calculates the experience modification factors. NCCI is the governing bureau that produces these calculations for most states in the U.S. Most businesses have an individual experience modification factor produced each year and that factor is a critical component in determining a Workers’ Compensation insurance premium.

Essentially, NCCI will be changing the formula to place more weight on primary losses. Meaning, the new formula includes more primary or undiscounted claims dollars and less excess or discounted dollars. This change will be a step up program over three years, so, any financial impact will be over that period. Therefore, many businesses will see their experience modification factor increase, which typically equates to higher Workers’ Compensation premiums.

Due to several variables used in the calculation, coupled with an individual business’ personal experience, it is impossible to make blanket statements about how this will ultimately affect most businesses. However, there is a very strong possibility that the overall increases in medical costs for workplace injuries will adversely impact the mod calculation.

This change is real and it will likely have a negative financial impact on most businesses.

Suggested Courses of Action If business owners have not acted upon these changes, it is strongly suggested they take a proactive approach to this threat to mitigate the consequences of these changes.

Aggressive loss control, improved training and hiring practices, light duty, claims management are all directly related to claims experiences. Brokers or agents should be able to run a test mod, taking into consideration pending changes from NCCI. Business owners should ask their broker or agent to conduct a risk tolerance analyses, develop or refine risk mitigation procedures and execute an account positioning strategy. This will demonstrate why the business is a better-than-average risk, therefore, deserving of better-than-average pricing.

Paul Allen, 1951-2012 Paul Allen, an industry professional from Hoover, Alabama, passed away on February 11, 2012 after a two-and-a-half year battle with pancreatic cancer. He was 61 years old. Paul was founder and co-owner of CSDA member ABC Cutting Contractors of Birmingham, part of The Coring and Cutting Group. Born in Kentucky in 1951, Paul graduated from the University of the South in Sewanee, Tennessee, and received his MBA from the University of Alabama. He followed in Paul Allen his father‘s footsteps by working at R.R. Dawson Bridge Company before joining ABC of Atlanta in 1985. A year later, with the help of Larry McCoy, Paul started ABC Cutting Contractors with two trucks. The company joined The Coring and Cutting Group in 2009. To help visualize a particularly challenging cutting job, he once built a large-scale model out of Legos and, despite his helpful and generous nature, was known for his humorous use of the phrase “no good deed goes unpunished.” Outside of work, he was a Boy Scout Leader for Troop 367 at Riverchase United Methodist Church. He is survived by his wife of 31 years, Donna; two sons, Loren and Kaden; a daughter, Jessica; a grandson, Paul; two sisters, Paula and Ann and a brother, Wayne.

MEMBER TESTIMONIAL We have been a CSDA member for seven years, but up until last year, we did not take advantage of the many valuable tools the association has to offer. Since then, we have participated in CSDA Operator Certification courses to become more proficient and productive when cutting, and have benefitted from the many Best Practices and safety documents. We have also had a job story printed in Concrete Openings [March 2012], with which we are very pleased.

These things, together with my experiences DJ Conlon at association meetings and with the Next Generation Committee, have all proven to be invaluable to the company.

As I began to get involved with the administrative side of the business, I learned that the key players in the industry are usually involved with the CSDA. The opportunity to network and learn from other contractors was something we could not ignore, so joining CSDA and becoming an active member was a no-brainer.

WHEN THE SIZE IS NOT A PROBLEM!

“ … with its 20 mm in diameter it can make very large cuts, it’s very helpful when we have to do particular jobs. Unique.,, Francesco, Italia

“… if we cut steel we have no problems using this electroplated diamond wire with conical beads.”

Adam, New Zeland

“… cutting concrete and reinforced concrete it has become simple, the only problem we have is to choose between cutting speed or tool’s life.”

Yuri, Ucraina

“… contingencies are always around the corner, but if we have the right solution we can rest quiet.

With the thin wires it’s all much simpler.”

director’s dialogue

CSDA’s Next Generation

Patrick o’brien Executive Director

C

SDA’s 40th Anniversary was a time to look back and celebrate the accomplishments achieved since its founding. CSDA certainly has much to be thankful for but I doubt that the contractors and manufacturers who founded CSDA in Southern California in 1972 could have foreseen how powerful their founding goal to “provide a forum to promote the concrete cutting industry, share information and introduce new technologies” would become. However, as CSDA acknowledges the past, and those that have made the association so successful, it also has a keen focus on the future.

At the March CSDA Convention, a new logo and brand identity were introduced to replace the 40-year-old logo. The new logo reflects the change in the industry from when the first contractors performed only sawing and drilling services. The original logo contained a saw blade and core drills and perfectly demonstrated the work that the contractors performed. Today’s contractor has expanded into many related services such as Ground Penetrating Radar (GPR), recycling, wire sawing, selective demolition, concrete polishing and concrete flatwork. The new logo has broad appeal to cover the many different services offered by CSDA’s contractor members.

The logo and brand identity are important, but what about the people who will lead the association as we head into the next 40 years? The leaders of the first 40 years, the CSDA Past Presidents, initiated a program a few years ago to involve the younger generation in CSDA. This idea led to the formation of the CSDA Next Generation Committee. Its purpose

6 4 | J U NE.1 2

statement is to “cultivate continuous leadership for the CSDA through education, mentoring and networking.” An immediate goal is to bring more second tier owners into the association, propose a plan to draw young employees into the construction industry and help to recognize where the industry is headed. In just a short period of time, this committee has become very effective at involving and creating excitement among the younger generation.

The Next Generation effort is more than just finding CSDA leaders for the next 40 years. Many of the original contractors who founded their companies have, or are retiring, and the sons or daughters are taking over the businesses. The transition of business from parent to child is an important one, and the Next Generation group is helping one another to make this a smooth process. These new business owners can look to the past for knowledge, advice and mentoring and look to the future for inspiration, leadership and innovation. A key factor in these transitions is to understand the importance of adapting companies to the new employee mindset and learning to adapt to new market and financial challenges.

My first career was in aeronautics as an engineer, and I often read about great scientists and engineers. A favorite quote of mine was from Sir Isaac Newton, who stated in talking about his many accomplishments, “If I have seen further, it is by standing on the shoulders of giants that have come before me.” The CSDA Next Generation can accomplish much by building on the successes of the CSDA “giants” from the first 40 years to build a future that is unlimited in potential for them and the association.

Cut deep.

When you need to cut more than a few inches, Husqvarna’s extensive line of power cutters has you covered.

The K 970 Ring and the hydraulic K 3600 MK II allow cutting up to 10", twice the depth of a traditional power cutter. They are perfect for contractors who have to adjust window and door openings. The power cutters are also able to handle heavy-user, precast and even ductile iron pipe applications.

The K 970 Chain is ideal for cutting small, irregular openings. It finishes corners and avoids overcutting, making it an excellent companion to a wall saw. The saw can cut as deep as 15" from one side.

Our deepest cutters, the K 760 Cut-n-Break and Electric K 3000 Cut-n-Break, are intuitive, economical and versatile saws that make cuts up to 16" deep. The twin blade configuration enables high cutting speed and power to cut through a variety of materials.

Giving you options.

Not only will our saws cut to the required depth, but their reliability, ergonomics, efficiency and power set them apart from competitors.
