B R E AKI N G G R O U N D By Becky Schultz

Look Beyond Industry Walls for Workers I RECEIVED A CALL FROM A long-time reader in response to my column on the need to “Break Down the Workforce Barriers” (Equipment Today, May 2019). In addition to sharing his concept for a program designed to target young recruits into the construction industry, he shared some of his views on

Becky Schultz / bschultz@acbusinessmedia.com

the reasons behind the labor challenge the industry is now facing.

The reader, whom I’ll dub “Bill”, began his career as a laborer and, over the span of a few decades, worked his way up to executive-level management positions. He saw and experienced a great deal throughout his tenure in construction.

Bill and I chatted at length, during which he shared some of his concerns about an industry that he “dearly loves” and spent 40+ years working in. Specific to my column, he stated that the labor shortage “has been coming on for decades,” and in his opinion, the industry has been trying to solve it in “ridiculous” (ineffective) ways.

Bill believes part of the problem stems from a lack of initiative to reach people outside of the construction community — in other words, discussions about career opportunities in construction are far too insular.

“We keep within our own little bubble,” he asserts. “The only people we talk to are people who are already in the industry.”

Rather than focusing on how to onboard the next generation of family members or friends, or promoting careers to attendees at industry trade shows and events, Bill believes the discussions must extend beyond the industry’s own walls to reach a broader audience. And the focus needs to be on the chance to climb quickly up a highly rewarding career ladder.

But to do this, “you have to understand that the ladder is there,” he says.

“THE ONLY PEOPLE WE TALK TO ARE PEOPLE WHO ARE ALREADY IN THE INDUSTRY.”

Bill agrees that discussions about job opportunities should start with young people as early as the middle school level, and should cover the vast array of highly skilled, high-paying jobs available. He cited examples such as surveyors, drone pilots, safety personnel, engineers, and other roles found on modern jobsites, all of which require a high level of skill, yet don’t necessarily require a college education.

“You don’t have to spend $130,000 in college tuition to make $100,000 a year,” Bill adds, citing himself as an example: he started as a laborer at age 15 and retired as a company vice president.

His concept was a program focused on educating young people about how construction really works, and to reach them using the mediums they turn to most, whether it’s television, YouTube, podcasts — “whatever they use nowadays.” While such a program would require a great deal of coordination, construction firms can take advantage of these mediums to raise awareness of career opportunities, educate viewers on how the industry operates and “build” an audience of future new hires.

Bill had plenty more to say, which may prove the spark of an idea for other columns down the road. In the meantime, I thank him for the call, and I hope to hear from him (and you) soon! ET

The electrohydraulic (EH) controls on Caterpillar skid steers are an enabler for automation and integration of many performance-enhancing functions that can assist with repetitive tasks by allowing the user to set up the machine to do the work with less user interaction and expertise. One example is dual self-leveling, which electronically and automatically levels the loader linkage when raising and lowering the lift arms. The system ensures optimum material retention and control whether truck loading material or handling palletized products.

Ignoring

By Curt Bennink TRU CKS & TRANS PORTATION

Aftertreatment Systems

Can Be Costly I

ncreasingly stringent diesel engine exhaust emissions regulations have, over the past 20 years, reduced output of nitrogen oxides (NOx) by 95% and particulate emissions by 90% in heavy trucks.

These impressive reductions in NOx and particulate emissions required development of newer, sophisticated aftertreatment technologies.

Today’s diesel engine aftertreatment systems include a diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and diesel exhaust fluid (DEF) injector and mixer. “Each of these three subsystems reduce different types of emissions,” says Jim Nachtman, Navistar’s director of product marketing, heavy duty. “Today’s systems have been highly refined and deliver very high uptime.”

But the complexity of these systems cannot be ignored. Error codes and warning indicators need to be dealt with in a timely fashion. Successful fleets realize that a proactive approach can avoid costly repairs and the associated downtime.

One of the more common issues that can create problems with modern engine aftertreatment systems is air leaks in the intake and aftertreatment plumbing. “Air leaks typically impact the engine and aftertreatment system by affecting engine combustion, and changing characteristics of the exhaust,” says Jeff Granger, director of technical services North America for quality and satisfaction, Volvo Group Truck Technology. “Typically, boost air leaks, or improperly serviced air intake systems, result in excessive engine-out soot for the DOC and DPF to manage.”

An audible noise change from the engine can be one clue indicating a possible air leak.

“Perform troubleshooting on the air leak causes. Also, MIL faults can indicate when the system is not performing as designed.

Troubleshooting of those faults could indicate air leaks as a cause,” says Granger.

The engine’s sensors and OBD

monitor air flow through the engine and can detect leaks. “If an air leak is detected, it should be addressed. Items such as CAC hoses should be inspected for cracks or abrasion and addressed proactively,” Nachtman advises.

Excessive soot creation is a leading cause of downtime. “The most common cause of aftertreatment-related downtime is over-clogging of the DPF and associated too-frequent maintenance and cleaning,” says Alex Parker, executive vice president, Redline Detection. “The root cause of this over-clogging is unmetered air leaks that cause the vehicle to throw on more fuel, costing fuel economy and making a richer mix that quickly clogs up DPF filters, increasing costs of DPF maintenance and cutting into uptime.

“Finding and fixing unmetered air leaks is essential to solving aftertreatment problems,” he adds.

Leak testing should become part of your regular routine. “The best practice being used by large 3% Exhaust Flange Cracks and Gaskets 1% Intake Gaskets fleets is to perform a 10-minute 3% Water/Exhaust Intrusion leak test as part of routine maintenance,” says Parker. “For trucks 6% in severe-service conditions, leak V-Clamps on Turbo detection as part of regular or Cracks scheduled maintenance for intake and exhaust systems 26% is absolutely essential, just Clamps/Tubing 8% like changing the oil. to and from Blocked Pressure “Because air leaks in the CAC Differential Switch Tubes the intake and exhaust system are the most common cause of 9% aftertreatment failure DPF Gaskets and and excessive mainHousing Failure tenance, maintaining the seal and integri17% ty of your intake and V-Clamp/Gaskets/ exhaust systems will 11% Exhaust Tubing give you the biggest Charge Air Cooler Cracks on DOC/SCR payoff,” he continues.

ROOT CAUSES OF

BOOST LEAKS

A proactive approach minimizes downtime resulting from diesel engine exhaust aftertreatment failures. repair of problem vehicles and increase your uptime.”

Air leaks will occur over time.

“As vocational vehicles cover millions of miles, often in grueling conditions and inclement weather, the best-made vehicles — tight when they rolled off the assembly line — rumble loose,” says Parker.

“Those jarred, cracked and worn components are often the root cause of hard-to-diagnose aftertreatment problems.”

Any time an aftertreatment system has been serviced, check for leaks. “It’s 100 essential to leak test a vocational vehicle after routine DPF cleaning 80 to ensure that a leak has not been unintentionally created during 60 the reinstall of the filter,” Parker advises. “An efficiently functioning 40 intake and exhaust needs to be completely sealed to run at peak effi20 ciency. Air leaks are often overlooked, causing sensors to commu- 0 Image credit: Redline Detection nicate bad data; then sensors are unnecessarily replaced as bad. Fleet operators can cut parts and labor costs — avoiding ‘parts darts’ replacement of expensive components — by leak testing to pinpoint the problem. Faulty components creating air leaks are most frequently inexpensive gaskets, valves and clamps.”

It is easy for the technician to inadvertently introduce air leaks into the system. “In the event of any engine repair, it’s essential to ensure that the intake and exhaust are completely sealed for efficient operation of the aftertreatment system,” says

Parker. “A 10-minute leak test will confirm the system’s integrity with 100% certainty.”

Even small leaks can cause early plugging of a DPF, increasing maintenance costs, hurting MPG and cutting into uptime.

“Ultimately, a simple air leak can cause a lean condition that will cause an excess of temperature in the exhaust system, which can cause a thermal event, rendering the DPF inoperable and triggering a costly replacement,” Parker explains. “This thermal event can

ENSURE ENGINE HEALTH Aftertreatment systems are typically robust. It is the upstream failures that must be monitored since they can lead to system faults. “Issues can occur if DEF quality is poor, making it important to purchase a high-quality DEF,” says Nachtman.

If an engine consumes more oil than the engine manufacturer’s guidelines, ash can prematurely plug the DPF. “Oil consumption

Other engine-related problems can also lead to premature DPF filter plugging. “This includes EGR system failures and other engine issues that interfere with proper engine combustion,” says Granger. “The best approach is

Engine condition can influence the amount of ash being collected by the DPF. “When an engine reaches its end of life, oil consumption may rise when the piston rings are worn out,” says Nachtman. “This will cause the DPF to accumulate ash faster.”

As the engine wears, the increase in oil consumption will increase the ash loading of the

TOOL SAVES REPAIR TIME Checking for air leaks in modern diesel engines can be a challenge.

You need to safely replicate the boost pressure in the system typically produced by the turbocharger.

Developed in collaboration with International Trucks, the Redline Detection HD PowerSmoke replicates high-pressure boost load so the intake and exhaust systems can be tested for faults with the engine safely off. It can reliably detect high-pressure and low-pressure upstream faults, pinpoint exact locations and precisely identify failing components.

The results of successful leak detection and repair have been impressive. Technicians have reported that 96% of excessive forced regens are being eliminated. Fleets are also reporting an increase in fuel mileage by eliminating performance-killing upstream air leaks. By ending unresolved upstream faults and the associated aftertreatment issues, the technology is dramatically cutting warranty costs and comebacks. engine. “Excessive oil or coolant consumption by the engine can have a negative consequence on the Engine Aftertreatment System (EATS),” says Granger.

“The EATS can be contaminated by liquid oil or the oil can be oxidized in the DPF, leading to excessive ash loading that will require the DPF filter to be cleaned prematurely.

Also, coolant consumption can contaminate the DPF by the coolant chemicals being captured in the DPF filter, requiring cleaning. If an engine issue is

to follow maintenance guidelines and do not ignore MIL fault.

Quick attention to issues will reduce unplanned downtime.”

The engine and its aftertreatment system are engineered to work with the recommended fluids. Don’t deviate from the recommendations. “CK-4 and FA-4 oils are specially formulated for use in 2017 GHG engines, and help reduce ash accumulation in the DPF,” Nachtman points out. “Using older oils can reduce the DPF cleaning interval.”

DPF. “This will require the DPF to be cleaned to remove the ash,” says Granger.

KEEP UP ON RECOMMENDED MAINTENANCE The maintenance on upstream components has a direct impact on the aftertreatment system.

For instance, fuel injection system faults are one of the most common causes of increased particulate matter, which is captured by the DPF. Other common upstream issues that can create problems include dirty air filters

that restrict air flows and leaky turbocharger oil seals.

“Regular maintenance of the engine is important to keep the system healthy and performing normally,” says Granger. “The EATS system performance is directly influenced by the inputs to the system. The primary inputs to the system are the exhaust constituents from the engine (gaseous and soot concentrations), and the DEF injection into the EATS system. Proper maintenance of the engine and EATS system are important to maximize system performance and life.”

The application has an influence on how you track DPF cleaning intervals. “When operating in a vocational application, many customers will need to clean the DPF based on hours instead of mileage,” says Nachtman.

Some fleets have elected to shorten DPF cleaning intervals based on their experience in their particular applications.

If the DPF becomes excessively plugged, it becomes harder to clean and more susceptible to damage. These ceramic filters can cost several thousand dollars and can be easily damaged or cracked if handled improperly.

Fuel injector failures or turbo problems can also create issues with the DPF which require cleaning for proper operation.

What happens upstream affects downstream components. Any failures upstream require careful attention to aftertreatment components to avoid bringing trucks back into the shop. Successful fleets have proven that engine aftertreatment system costs can be successfully managed. ET

t has been nearly two years since OSHA revised its longdormant silica dust exposure regulation. The new exposure limits are microscopically low, and it kind of makes you wonder what the heck we’ve been breathing all this time.

Asbestos and lead dust? We get it — the hazards are well defined.

But silica? Every sandbox and dusty ballfield is loaded with it. It is a naturally occurring element in practically all natural environments. And all of a sudden it’s blood poison? Hard to figure.

Enforcement of the new standard had been spotty, right up until last summer when Virginia Occupational Safety and Health (VOSH) cited a large regional contractor for three “willful violations of the Silica Rule.”

The “willful” category essentially quintuples the proposed penalty, bringing the dollar amount close to $100,000 for each of the three transgressions.

The odd thing about it is the contractor is no slouch when it comes to safety, so either someone got very lazy or VOSH decided to send a message.

Either way, it’s a wake-up call to the rest of us.

If your employees have any exposure to silica dust — yours or anyone else’s — you have some homework to do.

“HOW MUCH DUST IS ENOUGH?” This is what OSHA calls the “Action Level” and it’s really low — 25 micrograms per cubic meter of air. The only way to measure it is to bring out an industrial hygienist to take an actual reading of how much silica is in the air.

The next number to watch is the Permissible Exposure Level

BONUS TIP:

which is basically a long list of dust-producing jobs and a description of the required safety controls and exposure duration for each job. (View Table 1 at https://bit. ly/300MO2d.)

If you can find your job on Table 1, and you stay within the strictures of the specified work activity and safety controls, you should be okay, even without Action Level testing.

Staying within the strictures is very important; going outside the lines can open you up to a penalty. So if you choose to use Table 1, it’s not going to be a random call.

In all cases, you will need a Written Exposure Control Plan.

This plan defines your company policy and details how you will comply with Table 1, for example, or any other protective measure in the standard. Add this plan to your safety manual, just as you would any other regulatory safety requirement such as hazcom or personal protective equipment (PPE).

You will need to train your employees in the intricacies of staying in compliance with Table 1 and any other provision, such as respirator use; using water or vacuum to minimize dust; staying upwind from

(PEL), which is 50 micrograms per cubic meter of air. Just for comparison, that’s the rough equivalent weight of an eyelash or the wing of a fly.

Consequently, if you can see dust, you are probably overexposed and need to take action.

COME UP WITH A PLAN As part of the Silica Standard, OSHA published Table 1,

REPAIR TO SPECIFICATION If you bought a pavement saw equipped with a water delivery system and that system breaks or fails, you cannot substitute by using a garden pump-type sprayer to deliver the water — even if the first generation of water delivery hardware on the saw was notoriously prone to failure and the latest tooling is built more robustly.

This is important because OSHA will consider any hardware improvisation to be non-compliant, even though it might be equally effective. Hardware must be maintained in accordance with the manufacturer’s instructions and original equipment.

Fortunately, most of the tool makers have gotten the message by now and have refitted and upgraded their hardware.

dust; using PPE properly, etc.

Document this and all safety training.

Bonus tip: Issue a wallet card as a reminder to each employee that they have been trained.

ESTABLISH A “COMPETENT PERSON” FOR EACH JOBSITE You will need to train, educate and authorize a Competent Person (CP) for the jobsite to keep an eye on all the safetyrelated pieces and parts along the way. This person will need to: ˜˜ know how to minimize creating dust on any site by using Table 1 or any other means; ˜˜ understand the OSHA Hierarchy of Controls (Engineering, Administrative, PPE) to properly protect employees; ˜˜ be named in the Written Plan, along with others having authority for the Silica Program; ˜˜ have the authority to make changes and stop any work deemed to be unsafe.

In addition, you should name this person(s) with a Certificate of Competency, a letter and a wallet card. This is their reminder so they don’t get amnesia if an inspection occurs.

Frequently Asked Questions OSHA has posted frequently asked questions (FAQs) on the standard for respirable crystalline silica in general industry. The FAQs were developed in consultation with industry and union stakeholders to provide guidance to employers and employees on the standard’s requirements, such as exposure assessments, regulated areas, methods of compliance and communicating silica hazards to employees. The questions and answers are organized by topic, and include an introductory paragraph that provides background information about the regulatory requirements.

Find the FAQ at https://bit.ly/2X14IQL. Find more information and resources on compliance on OSHA’s silica standard for general industry home page at https://bit.ly/2yNsacj.

silica dust. The only reliable way to do this is to have a representative job tested and documented by an industrial hygienist.

The estimated average cost for an industrial hygienist to come out for a day and sample

your actual silica exposure is about $1,500. This includes all the baggage, hardware, test results, etc. It’s not a bad price for an insurance policy that lasts as long as you’re doing this type of work or work that is substantially similar.

When you add up all the elements required in the silica control program, it is a laundry list. But the good thing is you only need to do most of it once, as long as your business and the jobs you perform remain roughly the same. ET

trades, but the OSHA rubric on respirators can be confusing.

For example, the voluntary use of dust masks still requires that the employer makes sure the employee can safely and properly wear the mask, i.e., proper seal, no facial hair, etc. (The three-pack-a-day person is probably not going to pass the test.)

If you plan to be in business for the foreseeable future, it probably makes more sense to have the entire crew fit-tested and medically certified for respirator use. This removes any doubt about their ability to breathe freely.

Recertification on this respirator test is required annually. OSHA and your general contractor will ask for these records.

COMPLIANCE = PROTECTION For the business owner and manager, compliance with the new silica rule is not all that complex. And OSHA did its homework on Table 1.

We advise you don’t try to push your luck on it. Stay within the category guidelines and document it.

A big factor in your Silica Program will involve being able to prove your employees are not exposed to any astronomical (i.e. visible) levels of

MACHINE CONTROL Machine control technologies address worker shortages and productivity gaps.

M

achine control technologies range from 2D and 3D grade control to automation, robotic control and augmented reality. These innovations have permanently changed the competitive landscape and continue to evolve.

The technology addresses several pressing challenges including a shortage of qualified labor, a demand to increase productivity to address the infrastructure backlog and a need to squeeze out profitability in an increasingly competitive environment.

28 EQUIPM ENT T OD AY | July 2019 ET0719_28-31_MachineControl_CB.indd 28

In the hands of skilled operators, machine control technology promises to raise productivity to address population growth’s infrastructure challenge. While the world population is projected to grow from 7 billion in 2012 to 9 billion in 2035,

there remains a $36 trillion gap in global infrastructure funding. This gap is exacerbated by increased construction costs and an actual dip in construction productivity.

A digital revolution promises to reverse this trend. Case

interface with modern electrohydraulic systems to provide semi-autonomous functions and customized capabilities that make novice operators more efficient while reducing fatigue in experienced operators.

Similar to advancements in computers and smartphones, the advancement of machine control interfaces makes the machines more powerful. Many interfaces now use touchscreen technology that operators are already familiar with through personal smartphones and tablets.

Operating parameters, including hydraulic flows and pressures for multiple attachments, can be stored and changed via the operator interface.

In addition, graphical interfaces allow operators to quickly and accurately assess where they are compared to the target grade. An example of this technology is Volvo’s Dig Assist (www.ForConstructionPros. com/12313594). Powered by the Volvo Co-Pilot in-cab tablet and incorporating sensors and the latest location technology (GNSS), Dig Assist maximizes excavator productivity by making it easier for operators to dig, trench and excavate. These technologies usually allow operators to design certain jobs in the field with the onboard tablet, which can eliminate the need for surveyors to mark out the excavation site.

Onboard payload weighing systems, available from many of the major OEMs, are allowing

Cat Grade with Assist enables the operator to set and quickly and confidently get to grade without using GPS. When it sees the opportunity, the machine will automatically modulate the boom and the bucket functions. Photo Credit: Caterpillar loader operators to be more precise and efficient by providing real-time intelligence to the operator and documentation for project customers. These systems typically achieve an accuracy of +/- 1%. With real-time insights into the bucket’s load, operators can eliminate over-loading, under-loading, re-weighing and waiting times in addition to tracking the loading progress.

Other tools are emerging to help operators use this information. For instance, Volvo is adding an Operator Coaching functionality to its Load Assist program for wheel loaders (www.ForConstructionPros. com/21008380). As machines become more advanced with smarter technology, Operator Coaching helps ensure operators use machines to their full potential. Volvo’s app provides real-time guidance to operators on issues including idling, braking, throttling and engaging the transmission lock-up, helping them understand how their actions influence machine productivity and efficiency. It also identifies areas for improvement.

The next step in operator interface may include

PRODUCTIVITY BOOST Automation cuts the learning curve for equipment operation, especially with complex machines such as excavators. Human operators can take years to develop operating expertise. But construction vehicles with automation can be programmed ahead of their first day on site with all the data and learnings of all other machines that preceded them.

Charleston, SC-based Landmark Construction has witnessed a jump in production with its Trimble Earthworks-equipped excavator. With the previous generation 3D systems being used in its operations, the operator had to look at the grade control screen and coordinate the bucket in the proper position to achieve grade. The semi-automatic feature no longer requires the operator to focus as much attention to the screen. The system allows the operator to control the stick, while the boom and bucket are controlled by the automated system to stay on grade.

“With the automatics, you can carry the grade 100% of the time underneath the machine where the operator cannot see,” says Mike Marshall, Landmark’s survey superintendent.

The goal with these grade control technologies — including Caterpillar’s Connect Technology — is to increase operator productivity. Cat Grade with Assist (www.ForConstructionPros.com/12129871) enables the operator to set and quickly and confidently get to grade without using GPS. “When it sees the opportunity, the machine will automatically modulate the boom and the bucket functions,” says Brian Stellbrink, excavator market professional at Caterpillar. “We need machines that are going to help make average operators better and make very good operators less fatigued.”

Construction’s Productivity Challenge is Really about Technology Adoption www.ForConstructionPros.com/21018854

AUTOMATION IN THE AFTERMARKET Aftermarket suppliers are also developing products to automate existing earthmoving machines. For instance, San Francisco, CA-based Built Robotics supplies kits to automate construction equipment using off-theshelf sensors and equipment. Proprietary software allows machines to work autonomously. The kits are available for all late-model dozers, excavators and skid steers — essentially any vehicle on which you can install automatic grade control systems.

This technology is rapidly expanding to the rental market. Built Robotics and Sunstate Equipment recently formed the construction industry’s first partnership to rent autonomous equipment to contractors around the U.S.

5G WILL ADVANCE THE FUTURE OF AUTOMATION One technology that promises to enable future machine control innovations is the introduction of 5G broadband networks. Volvo Construction Equipment is among a small number of companies experimenting with 5G mobile connectivity.

“A faster, more reliable mobile network will mean we’re at the forefront of driving a much faster market implementation of technologies like automation,” says Calle Skillsäter, technical specialist for Connected Machines at Volvo.

Something that had seemed impossible a few years ago is now a very real opportunity today. With the reduced latency that 5G provides, it really does mean you can achieve remote operation from extremely far away.

“Safety is obviously a big factor, but clearly 5G will have a direct positive impact on productivity,” says Skillsäter. “Today’s remote-control technology provides a delay which makes it very difficult to control a machine with any speed or precision, but 5G will be as good as real time.

In addition, the picture quality is much better, video footage is in a better resolution and 5G provides a more reliable connection — all of which makes it easier for the operator in the simulator.”

AUTOMATION ADVANCES Software advances are driving an increase in mobile machine autonomy. According to Case Construction Equipment, with increasingly diverse hardware and software being used to sense, collect, analyze and apply control, it’s possible that entirely new ways to operate today’s machines may come about tomorrow, such as semi-autonomous or fully autonomous systems.

We are already seeing many semi-autonomous machine control solutions — including 3D excavator systems with automatic capabilities — emerging from companies such as Trimble, Topcon, Caterpillar, Leica, Kobelco, Komatsu and others.

The technology continues to advance at a rapid pace. For example, Kobelco has worked closely with Trimble to develop an advanced machine control system that does not use specialized (and potentially expensive) electronic sensor cylinders or mechanical controlled position

By removing the masts and leveraging position sensing, the operator of John Deere’s SmartGrade motor grader can now run without limitation, using all of the machine functions (e.g., blade pitch, circle side shift and circle rotate) without risking damage and all while staying on grade. In the cab, the grade system interface is built into the Grade Pro controls, available in the Deere-exclusive fingertip or dual joystick design. Photo Credit: John Deere sensors, but state-of-the-art gyroscopic sensors. These new sensors are similar to those used in modern airliners and stability systems on automobiles.

Automation can sometimes be achieved by simply upgrading existing hardware. For instance, a new joystick, TS-i4 inertial sensors and interface convert Topcon’s 3D X-53x indicate system (www.ForConstructionPros. com/21063409) to an automated depth and bucket control system.

The X-53x can control depth of excavation and angle of the bucket automatically. A new calibration method relies on a total station for reference, and the system’s AI controller determines hydraulic settings automatically based on its calibration routine.

Scan the QR code, or visit https://adobe.ly/301RhRa, to access the interactive version featuring added insights on machine control technologies.

Wheel loaders are another machine form that has progressed from return-to-dig and return-to-carry machine control functions to more autonomous offerings (see www.ForConstructionPros. com/21067261).

For example, Komatsu offers an automated digging feature.

By monitoring work equipment pressures, the wheel loaders initiate digging motions at the optimum time, reducing operator fatigue with 20% to 30% less effort in V-cycle loading. Transmission kickdown is integrated into the automatic digging system, eliminating the need for the operator to manually engage the transmission kickdown button. ET

P R OFI T MAT T E R S By Nathan Medcalf

Contractor on Path to a

BIG, HAIRY GROWTH GOAL Barton Malow sees 15% efficiency gains from implementing 3D modeling technology.

Barton Malow continues to push its modeling technology into the field to give all stakeholders access to the sources of data that build their plans and help them perform better.

W

e are builders not brokers,” says Matt Hedke, Barton Malow senior virtual design and construction manager. “We want to understand how every piece and part go together. Trimble has a similar culture. They want to understand how we are using the tools and how can they make it better.”

Hedke describes Barton Malow — a Southfield, MIbased construction manager/ design-builder/program manager/general contractor — as an innovator in an industry slow to adopt technologies. That’s why it has been working with Trimble for more than 20 years.

“We want to partner with someone like us — someone who will adopt new technologies and push the envelope,” Hedke states. “Just like us, Trimble innovates, thinks differently and is concerned with putting technology into the field.”

Barton Malow upgraded the 2D modeling system it used for modeling concrete rebar design to Trimble’s Tekla 3D modeling system in 2012. “We have to model the concrete to put the rebar in

36 EQUIPM ENT T OD AY | July 2019 ET0719_36-37_ProfitMatters_BC.indd 36

it,” says Hedke. “No other software provider is as advanced as Tekla, especially with cast-in-place concrete and rebar modeling. We knew there would be a learning curve, but we embraced it because we knew the end result was where we wanted to be.”

The fabrication software Barton Malow was using at the time didn’t talk to the Tekla software, so Trimble had a few conversations with the provider.

Now, all the rebar comes right out of the model into the company’s fabrication software, and that information transitions through to its equipment.

Within a year of putting Tekla Structures to the test, Barton Malow was seeing efficiency gains upwards of 15%. “We now have seamless integration between our modeling software and our fabrication software.

We have been able to eliminate data entry, which means we can now eliminate human error and the increased time that is a result of manual data entry,” says Hedke. “Once the ‘gun goes off,’ we are on a tight timeline. We don’t have time for mistakes or inefficiencies.”

Barton Malow finds that the tools in Tekla’s software for scheduling columns and detailing slabs, base plates and stirrups drive efficiencies by enabling the team to rapidly add detail to drawings.

They’ve developed templates to create automated assembly tags, which provide instructions on how to pre-tie a cage to improve rebar placement efficiency.

“Before Tekla, we simply didn’t have the time or the tools to easily add this depth of detail,” says Hedke. “Our focus

was on detailing the rebar rather than the various components of the concrete object. Tekla allows us to see in 3D how everything will fit together and if we will run into clashes or interferences.”

Barton Malow prizes Tekla’s ability to quickly put previously overlooked details in 3D models of rebar design (such as these anchor bolt embeds).

IN PURSUIT OF A BIG GOAL

been able to increase productivity and improve safety.

“We use a phrase at Barton Malow: ‘plan the work; work the plan.’ Our go-to solution for site logistics is Sketch-up [another Trimble product]. We will map out our site, identify and capture our plan. From there, we use Tekla to begin to build out the concrete and rebar, plan pours, formwork, anchor bolts and much more in collaboration with our site teams,” Hedke points out. “All of this is done virtually before a shovel ever hits the ground.”

Barton Malow is pursuing a very big goal — what the company calls its big, hairy, audacious goal (BHAG). It was 2012 when the company decided to double its productivity by 2024, the 100-year anniversary of the company’s founding.

“The intent of the BHAG is to build a culture of continuous improvement and challenging the status quo. We want to look at every process then figure out how to make it better through a variety of means and methods. We feel like technology is a big piece of the equation,” Hedke explains.

The company is assessing each of its business activities line by line. “Because a lot of processes have remained relatively unchanged for the past 100 years, there is such a large opportunity to change,” says Hedke.

One of the keys to increasing efficiency is by taking a constructible approach. A constructible process integrates the complete building life cycle to manage construction activities and team collaboration and improve overall productivity. By combining design, project management and engineering models into a collaboration platform, data from different sources can be combined and used to make more informed decisions before build and beyond.

By taking this approach using technology, Barton Malow has

TECHNOLOGY TO THE FIELD One of the major changes Barton Malow is making is to get technology into the hands of its field staff.

With Trimble Constructible technology, all stakeholders have access to the sources of data that help them perform better.

For instance, the pre-construction teams can use the shared constructible data to perform estimates faster and more accurately. Likewise, field layout and fabrication can leverage the shared models and avoid potential errors due to rework.

“Feedback from the field has been positive. Technology and change are two things that typically create challenges with any person. Ensuring we are training and supporting our project teams is critical to our success,” says Hedke. ET

Surpass safety priorities by building tools that empower employees.

I

t’s common for companies to talk about their desire to create a culture of safety. But enacting a safety culture that actually makes the work safer demands more than making regulatory compliance a priority.

And the transformation doesn’t happen overnight.

“Safety culture is about measuring the presence of safety, not the absence of accidents,” says Don Swasing, CEM, quoting a respected safety mentor. Swasing is chief operating officer for Schlouch Inc., a Pennsylvaniabased site preparation company.

“A safety culture is the way in which safety is managed in the workplace. It most often reflects the attitudes, beliefs, perceptions and values employees share as they relate to safety.”

Compliance is the basic component of a company’s safety program, but a safety culture must go much deeper. In order to create a living safety culture, company leaders must commit to the transformation. A failure (accident or near miss) can often be used as a catalyst for change.

“We are focused on relationship-based safety,” says

40 EQUIPM ENT T OD AY | July 2019 ET0719_40-41_Safety_BC.indd 40

Kris Manning, national director of safety and vice president, Clark Construction Group, a commercial building and civil construction services firm with offices and operations across the U.S. “We don’t view safety as a priority. Safety is a core value to us. Priorities often change. A core value, on the other hand, represents the foundation of who you are and what you do. ”

IDENTIFY GOALS AND REWARD MILESTONES Driven by the desire to eliminate rollovers, Schlouch embarked on its transformation in 2014. The first thing the company did was assign a couple of key employees to investigate the root cause of these accidents.

“The findings were quite interesting,” says Swasing. “It was a combination of operational habits, along with a lack of education and time.”

Once the analysis was in, Schlouch leadership told employees of its intention to eliminate rollovers. A specific rollover prevention plan was developed and put into place. “Everyone in the company clearly understood that

this was a priority of senior management, and concrete steps were being put in place to address it,” Swasing says.

Schlouch has made great progress over the past several years. It has eliminated heavy equipment and tri-axle truck rollovers, which was leadership’s original intent. It is an important milestone, but the quest for a healthy safety culture continues.

“Leadership must be very open and honest when it comes to safety,” Swasing points out. “As we’ve transformed our culture, it has been important to celebrate results as they’ve happened.

When we went 100 days without an accident, it was big news. At 200 days, it was bigger news. You have to celebrate the good. At the same time, when you have a near miss, you have to immediately let everyone know.”

Clark Construction Group believes in the concept of celebration, as well. “Rewards are instrumental when trying to change behavior,” Manning says.

“We often have stand-downs where we have breakfast or lunch brought in to celebrate milestones. We’ll issue spot rewards

For Clark Construction Group, safety starts with camaraderie on the jobsite and the genuine, shared concern for each other’s safety. like TVs or tickets to a sporting event. We are excited to reward teams for strong safety performance.”

ACCEPT THE COLD HARD TRUTH In order to get to a place that “looks right” with respect to safety, leadership must first acknowledge the current state of safety in their company, then decide and communicate what is and isn’t acceptable.

At Schlouch, superintendents and the fleet coordinator assessed the current state of safety, then reported their findings to the CEO. “It could have been easy to make excuses for our rollovers, i.e., the operator was inexperienced or the underfoot condition was poor,” Swasing says. “But at the end of the day, a lot of our problems had to do with unsafe acts and putting employees and machines into challenging situations.

S AFET Y & COMPL IANCE

“You have to be strong because there’s a risk in being honest about your current state,” he continues. “A lot of CEOs do not want to hear that things are messed up. It’s important to give the CEO confidence that you’re going to fix it. Trust is a critical component in cultural change.”

In order to establish the necessary level of trust, leaders have to be “present” on the jobsite so they can see the hazards and conditions for themselves.

“Safety leaders must be credible, respected and inspirational,” Swasing adds. “If they are trying to inspire change, they need to walk the talk every day. At Schlouch, we actually created leadership standards together as a team, published those standards and gave them to everyone in the company.”

Any leaders who do not embrace change threaten the credibility and viability of the safety transformation. It’s possible that they may need to be removed from the team.

REFOCUS ON RESULTS When trying to distinguish between a culture of safety and a culture of compliance, you must scrutinize what Swasing calls “compliance rituals.” He offers the following example: “We had a loss control person who went out into the field nine times a year to conduct audits. He would look at equipment logs, seatbelt on/off, backup alarms, housekeeping of trailers, etc. Then he submitted his report to me. Guess

CLOSING THE SKILLS GAP Successful workforce development activities start with targeted, local outreach at the K-12 level.

IN AN EVOLVING INDUSTRY I

f the skilled trades are facing a widespread workforce shortage today, then what does the future hold? The construction industry — like any other — is always changing.

Successful companies recognize disruption as it occurs, and they react accordingly. Meanwhile, those that don’t, fail to achieve their organizational goals and often see their bottom lines suffer over the long term.

The existing skilled worker shortage took years to become the significant issue it is today.

Addressing it will be a tall task for the industry, and doing so effectively will require a longterm commitment on the part of all construction contractors to embrace workforce development as a means to recruit, develop and ultimately retain the employees of tomorrow.

INVESTING IN THE FUTURE Good jobs in the construction industry are there for the taking, and the vast majority of contractors are committed to helping incoming workers learn, grow and develop on the job — all while providing quality wages and competitive benefits. But in order to find motivated and dynamic young people, companies must be willing to go beyond traditional methods of workforce development and invest some time, effort and resources into their activities.

The Association of Equipment Manufacturers (AEM) has found success in tackling the skilled worker shortage in the equipment manufacturing industry by bringing together various member companies to share best practices and tools to recruit the workforce of tomorrow. In doing so, AEM seeks to help close the skills gap by guiding its member companies in their efforts to specifically target young people at the K-12 level — through strategic outreach to students, educators, guidance counselors and parents.

Organizations in the construction industry can stand to benefit from leveraging such an approach, as well, and those willing and able to be proactive in exploring a diverse range of recruitment activities can help convince young people of the value of taking up a career in the construction industry.

While it takes both patience and follow-through on the part of companies involved, AEM’s workforce development program ultimately achieves tangible results at a local level.

MAKING CONNECTIONS One significantly overlooked aspect of workforce development is the importance of conveying the value of work being done in the construction industry. Employees don’t simply put up buildings. They help

advance society and benefit communities by creating homes for families, schools for children, roads and highways for commuters and hospitals for the sick and injured. Young people today want to be assured of the fact that their work will make an impact. But more than that, they desire opportunities to build lasting and rewarding careers for themselves.

A strong emphasis on training and development can help allay young employees’ concerns about the future. For example, the leading contractors of today are developing training modules for every organizational role — from general laborer to company president. As a result, when employees come to work for these contractors, a career path is laid out in order to ensure each individual can develop the requisite skills to meet his or her long-term professional goals.

BUILDING AN ENGAGED AND PRODUCTIVE WORKFORCE Workforce development activities serve to help organizations ensure they can obtain, train and retain the employees of tomorrow. However, success cannot be achieved unless there is a strong commitment from organizational leaders to establish an environment where people can obtain the skills they need to do the job, both now and in the future.

Raising awareness of the employment opportunities available in the construction industry begins with targeted outreach at the local K-12 level in order to drive impactful results and, ultimately, build an engaged and productive workforce.

Yes, the construction industry is always changing, and where it’s headed is very much up for debate. But what seems certain is it will be very different than it is

today, and construction contractors simply can’t afford to wait and see what the future brings without doing whatever is necessary to close the industry’s ever-growing skills gap. ET

A BLUEPRINT FOR SUCCESS In order to meet the expectations of the workforce of tomorrow and foster connections with qualified employees, construction contractors would be well served to undertake the following activities: »» Establish an employee ambassador program.

Encourage current workers to “adopt a school” and set up regular visits with instructors, guidance counselors, parents and students. »» Leverage social media to connect with a target audience. Create relevant and impactful graphics, share what it’s like to be a company employee, and highlight any cutting-edge technology being used on the job. »» Host a site showcase to demonstrate an organizational commitment to being a visible part of a local community, and answer questions about company values, priorities and activities. »» Provide opportunities for students to shadow employees and learn what it’s like to be part of an on-site construction team.

C

. Laney and Sons Construction is wellversed when it comes to rigorous jobsite conditions. It performs general construction, infrastructure, road building, site work and related projects, often at high altitudes and severe slopes in the Great Smokey Mountains.

Charles “Chuck” Laney, president and CEO, recalls one project where crews were rebuilding a fire-damaged facility, including demoing all of the concrete and removing the steel and iron and infrastructure.

The slopes were 45° or greater in most cases. “We actually have slopes that are 1:1 alongside of the road,” he notes.

“Our sites are very adverse.

They’re very demanding on the operator, they’re very demanding on the equipment. It’s easy to get hurt if you don’t pay attention,” he continues. “So, you need the best equipment and you need the best technology

that will enable you to produce the best product and do it in a safe manner.”

TECH SAVES MAJOR DOLLARS ON DIRT WORK C. Laney and Sons Construction provides comprehensive general contracting and design-build services to corporate, institutional and developer clients.

“We do general site work and we actually provide a complete product. We do infrastructure, road building and we also build buildings,” says Chuck. “The ability to have the equipment to facilitate our projects so we don’t have to wait on any excavation contractors has been a big asset to us over the years. It’s built our customer base very well.” He adds that an average project can be $25 million on up.

“We are a general contractor primarily,” agrees Luke Laney, VP of operations, and one of three sons involved in the family business. “But we do infrastructure and site work to get the complete job. We started that about 14 to 15 years ago.”

The company maintains a relatively small fleet of site work equipment. “We have anything from a Cat 299 skid steer all the

way up to a 336 excavator, but we don’t have a ton of them,” says Luke. “We do have some good operators and it allows us to do dirt work ourselves.”

C. Laney and Sons used rental over the years to help it build up its dirt and site work capabilities, but has also purchased equipment, including Caterpillar’s 323 Next Generation excavator. Luke notes that the machine is a good size for the company due to its versatility. “We can use it for utilities… It’s also efficient for loading trucks,” he explained. “It’s a small enough machine that we can move it easily, which is important where we’re at. We’re in a very mountainous terrain so we may not be able to get a 336 in to move dirt where we need to.”

The new machine has proven more fuel efficient vs. its predecessor. C. Laney and Sons has seen roughly half a gallon an hour in fuel savings with the new 323 vs. its 323F — around a 15% to 20% savings even given the rugged applications experienced. But that isn’t what impresses Chuck the most.

“I learned on levers when I first started operating equipment,” he recalls. “Older guys like me are usually afraid to see something new out there

— a touchpad in the cab, what is that? But the thing is, you take that touchpad technology and its ability to communicate with your equipment, and your younger and even your older operators, it makes your job more [cost efficient].”

For example, if the company puts in a mile of water line and the operator over digs the ditch 6 in. or a foot continually, it means an excess of spoils has been removed and must be disposed of, plus there is more backfilling required. “I could spend maybe $25,000 extra in a week for stone backfill because I over dug the ditch continually.

With this new equipment, I can tell the machine not to let [the operator] do that,” Chuck points out. Operators can also program it themselves. “The operator quits over-digging the ditch, and I’ve made more money for myself and my customer. As a contractor, our biggest job is to make sure the owner gets what they pay for. That’s our goal.”

The 2D system is used when setting block walls. “It’s very flexible for our operators. The wall system we use is very flexible, as well,” Luke says. Operators no longer have to follow stakes.

They simply reach out with the

The contractor has used slope grade control in many different ways, and not necessarily how they thought it would be used. “We use it if we’re digging sewer lines for rough grade so we don’t have to have a man in the ditch with a grade rod,” says Luke. “It’s one less guy, and it’s also safer. That’s a big deal for us, especially in the mountains, where we get some that are pretty deep. The sewer lines can be anywhere from 16 to 20 ft. deep at times.”

machine gained certain features introduced on the latest Next Generation models. “You couldn’t have done that with a different type of machine,” Chuck comments.

The update included a Lift Assist function. “I can see a lot of applications for that, especially where we’re setting manholes,” says Luke. In particular, he cites when operators attempt to boom out while

— but I love it,” he says. “Even the way the window opens is so much better… It’s so much smoother than an older machine, and that’s just a basic thing.” “[Technology built into the 323] helps in so many ways that we probably didn’t even think of when we bought the machine.

There’s a lot of things that we’ve discovered,” Luke adds. “It really helps save not just money and time on the job, it saves

“With [the e-fence], it helps protect that piece of equipment,” he points out. It also helps protect anything, or anyone, positioned behind it.

Chuck feels the telematics system on the Cat equipment is another asset well worth the investment. The system is set up to contact Stowers Equipment directly if there is a maintenance need and, as part of the service agreement, the dealer will send a tech out to service the equipment, whether it’s to change filters or oil or to resolve a larger issue.

“They have the historical data to tell us how much wear has

Chuck adds, “The machine is telling us what the grade is.

You’ve eliminated [the need for a grade checker in the ditch], and he can be doing something else — maybe even teaching him to run a machine.” The ability to avoid over digging on, say, a 20-ft.-deep trench also adds up to significant savings. “We might have cut $100,000 off of a project…”

CUTTING DOWNTIME AND MAINTENANCE COSTS Last fall, Stowers Equipment, the local Caterpillar dealer, sent technicians out to C. Laney and Sons’ location to install the latest tech upgrades onto the 323.

There are ergonomic benefits to the new excavator, as well.

Chuck notes that older machines often forced operators to crane their neck to look around the machine, or reach behind to access certain controls. Now, the touchpad lets you control functions with the push of a button.

He specifically points to how easy it is to use the touchpad to control the radio or HVAC system.

Chuck recently turned 67 years old. “All these things you would think I’d be afraid of

the machine itself. Sometimes guys can get pretty hard on their equipment and the Next Gen features help protect the equipment, which is a good deal.”

Take the e-fence feature, which provides automatic swing stop. While typically used to set a “fence” for the front of the machine, C. Laney and Sons is using it to protect the rear.

According to Chuck, when working on a mountain slope with large trees all around, there is a tendency for the machine to swing faster down slope. If the counterweight connects with a tree, it can mean $7,000 to replace a side panel, or upwards of $17,000 or more if you wrap a frame door around a tree.

AC Essentials Help Operators

KEEP THEIR COOL

Keeping operators comfortable is no sweat when air conditioning systems are properly maintained.

K

eeping equipment operators productive in the high heat months requires an air conditioning system maintained to harness some cool physics. Most of the maintenance is pretty simple, but knowing how and where refrigerant phase-shifts between gaseous and liquid states can make diagnosing problems pretty straightforward.

As with most equipment system maintenance, the most profitable AC system maintenance usually masquerades as mundane housekeeping.

Ask Robert Brocx how to prevent the most common failure modes for air conditioning, and he doesn’t hesitate. “Just by

e, bs, y”

fer

Air conditioning refrigerant straddles the major heat transfer potential at the borderline between its gaseous and liquid states.

The compressor raises pressurized gaseous refrigerant so that air blowing over the condenser will condense it into a liquid form.

keeping the condenser clean and not plugged with debris, and the fins not folded over from high-pressure washing,” says the technical steward (his actual title) at mobile air conditioning system maker Red Dot Corp.

“It’s pretty typical to get some hydraulic fluid or oil on the condenser,” he adds. A hose rupture or simple leak that makes its way into the air flow can coat the coolers. “It doesn’t look so bad, but it does impact the heat rejection of that condenser quite a bit.”

Oil is a bit of a problem on its own, but it’s not alone for long in off-road conditions. “It catches dust, and then you’ve got an insulating dust-and-oil mix on the fins, so you’re not getting good heat transfer. And it also blocks some air flow,” says Brocx.

Reversing fans in today’s equipment help clear dry debris from condensers and coolers, but they have limitations, particularly if there’s oil residue pasting dirt to the fins. Staying on top of this perennial problem isn’t rocket science. Someone has to inspect condensers and other coolers regularly, and make sure they’re clean.

Condenser

“The main thing is to look at the condenser coil regularly,” Brocx advises. “If it does have oil on it, check to see if it’s refrigerant oil. That indicates a refrigerant leak — and it’s a very bad thing [for the air conditioning system].”

CHECK CAB FILTERS TO ENSURE OPERATOR COMFORT Brocx cites maintaining the cab air filters as a second priority.

They’re seldom as easy to check as the condenser, but poor filter maintenance can cut an operator’s productivity even if the day is not terribly hot.

“Typically, there are two: a fresh air filter and a recirculated air filter,” Brocx notes. “Cab pressurization testing is done with clean filters. Once those filters start to plug up, you reduce total air flow, and you change your fresh- and recirc-air balance.”

Vehicle cabs are usually designed to have roughly 25 cfm of filtered fresh air coming into the cab. According to Brocx, this helps to: keep the operator alert since the oxygen in the fresh air displaces the CO2 content in the cab; keep the cab slightly pressurized; and, when it’s cold outside, keep cab air from getting so humid that it fogs the inside of the windows.

Again, frequency of filter maintenance depends on operating conditions. Discovering the right frequency for your machines is worth studying to determine an effective maintenance interval. It’s important to have replacement filters on hand when they’re needed.

“Sometimes people just remove the filters when they’re dirty without replacing them, but then dust is going to go right to the evaporator,” Brocx warns.

“Because the evaporator is wet [you’ve seen condensate draining

out of the systems], the dust is attracted to it and the inside of the evaporator just becomes a big mud ball. It will reduce air flow and really impact the cooling capacity of the system.”

FINDING REFRIGERANT LEAKS The third air conditioning maintenance priority is identifying refrigerant leaks. Most equipment uses O-ring fittings. Vibration and the impact of working off-road is far more stressful for those joints than for those in an on-road vehicle.

Over time, they tend to leak.

“You’ll be able to see that because usually you will get a moist spot where the refrigerant is leaking, and then it will attract dust,” Brocx says. “So, you will get a fitting just covered in dust.

Sometimes, you can see that it’s oily. If you have oily dust at a fitting, you can be pretty sure that’s leaking.”

Most OEMs put a UV-fluorescent dye into the refrigerant oil used in their AC systems. A technician wearing protective eyewear designed to enhance ultraviolet light can trace the system with an ultraviolet light, and where it hits refrigerant oil, it will glow.

Inexpensive aftermarket UV lights are also available.

“When you fix a leak, you really need to clean up that area... so the next person doesn’t think there’s a leak there again,” Brocx adds.

DIAGNOSTICS BY TOUCH Air conditioning works by manipulating the state of the refrigerant, applying and releasing pressure, cooling it in the condenser and warming it in the evaporator. Air conditioning delivers its value by making sure liquid refrigerant changes to a gaseous state in the evaporator.

It starts that process by releasing high-pressure liquid refrigerant through a tiny orifice into the line to the evaporator.

It is possible to learn roughly how well the AC system is working by cranking up the climate controls to max cool and air flow, and carefully touching

CHANGE OF STATE

Condenser some points in the system. In the lines just downstream from the evaporator’s pressure drop, the refrigerant approaches the transition to its gaseous state and becomes as cold as it will get in a typical AC system.

“Generally, the inlet to the expansion valve is going to be about 10° F or more warmer than the ambient air. And directly across the expansion valve, the inlet to the evaporator (usually it goes through a small manifold) should be very cold,” Brocx explains. “If it’s not cold right there, there’s a big problem. It might be that the expansion valve is not opening up.”

Low-pressure gas coming out of the evaporator should be about the same to 3° F warmer than the inlet. The pressure drop through the evaporator and expansion valve-controlled superheat pretty much cancel each other out, making the evaporator inlet and outlet close to the same temperature in a properly functioning system.

“If the outlet is 7° or more warmer than the inlet, then the system is probably low on refrigerant,” says Brocx. “If it’s 10° warmer, either your expansion valve is bad or you’re low on refrigerant.”

LEAKS DEMAND MORE THAN A RECHARGE When you suspect an AC system charge is low, confirming and correcting the problem is simple but not always intuitive. To confirm that a system is low, a certified tech should recover the refrigerant, weigh it and compare the amount to the OEM’s

Gas to liquid

specification for the amount required for a full charge.

“If the amount you recovered is significantly less, you know there’s a leak and can be pretty sure that it’s the low refrigerant charge causing the problem,” says Brocx.

“You should always replace the receiver drier when you have a leak because when refrigerant leaves through a leak, moisture is always going in,” he points out.

“System pressure doesn’t prevent moisture from traveling into the system. That’s like the No. 1 enemy inside the AC system.”

In fact, ingress of moisture through hoses is one reason AC systems have receiver driers. The rate of ingress is usually so slow that you don’t have to worry about it, but a leak will overwhelm the drier’s capacity.

Because the AC system manipulates very specific internal pressures to get the desired change of state where it is required, charging the system should be done carefully. System manufacturers prescribe a specific weight of refrigerant for each system they design, and recharging with just that weight is how a technician knows a system is charged accurately.

“The sight glass, most commonly located on the receiver drier, used to be a better indicator of system charge with R12 refrigerant and mineral oil because they were very miscible,” Brocx says. “But [today’s] R134a and PAG oil, under very high pressure, can look a little milky, like when R12 was low on charge. But it just indicates that the oil and refrigerant are not

mixing as well as the mineral oil and the R12 did.

“Actually, ‘milky’ isn’t quite the right word for the appearance of R134a. At high pressures, the oil and refrigerant don’t mix as well, so you see streakiness or stuff going past the sight glass,” he elaborates.

“Sometimes, it’s just clear like water; that’s usually at a moderate pressure like 150 psig. If the system goes to 250 psig, then it starts to look streaky. You see things going through there, and it looks like it’s low on charge.

If you keep adding charge, that’s just going to make the streakiness worse. Pressure is going to keep increasing and the system is going to be overcharged.”

Any time the condenser fan or compressor cycles — sometimes even when engine speed changes — refrigerant vapor bubbles can be seen going by the sight glass.

Brocx still uses the sight glass as part of his charging process, but he weighs the refrigerant going in as the primary indicator of charge.

“I think a sight glass is a great thing as long as you know what’s happening,” he comments. “If you’re checking on some other factors, too — like the temperature at the vents in the cab or pressures in the system — the sight glass becomes just one more factor showing you what’s going on in the system.”

IS THE HEAT REALLY OFF? Finally, Brocx says warm air mysteriously coming from the vents in the cab may require you to double check that the

The most important regular maintenance in an air conditioning system applies where the refrigerant changes state. Air flow is essential in the condenser and evaporator, and it takes deliberate maintenance to keep these systems working on construction sites. coolant or water valve isn’t leaking. During cooling season, the water valve should be shut off completely.

“On most construction equipment, all the cab air flows through the evaporator and then through the heater core,” Brocx notes.

Coolant circulating through the heater core will be about 180° F. The AC system’s refrigerant can only be cooled down to about 32° F, so the air leaving the evaporator might be 45° F. Run that through a 180° F heater core, and air might be coming out of your vents at 60° or 70° F. “Watch out if the AC system works really well when the engine is cold, but seems to stop cooling when the engine warms up,” Brocx cautions. “If the pipe coming out of the TXV [expansion valve] is still cold, most likely the water valve is leaking.

That’s one that comes up quite a bit.” ET

When the expansion valve allows line pressure on the way to the evaporator to drop, the refrigerant heads back toward a gaseous state, absorbing a lot of heat from warm cab air in the evaporator to complete the change.

Adapt for

COMPETITIVE ADVANTAGE In today’s environment, contractors must adapt their business or risk becoming obsolete.

I

considered four topics for this month’s column, but after taking a closer look, I decided that every one of them is important to every contractor out there no matter what size they are or what product or service they provide. If your company is doing things regarding these four topics, you probably have a competitive advantage — unless, of course, your major competitors are adapting to available changes in the marketplace faster than you are.

The four topics are: 1. Decisions about adding equipment during your busy season 2. Best practices for tracking equipment utilization and location 3. Managing risks in the age of technology 4. Finding ways to attract and retain quality workers without going broke We could spend a couple of days reviewing these topics, and I am positive most of you find them important. Yet, even if you believe they would make you more competitive, they are worthless unless you take steps to deal with them sooner rather than later.

ADAPT OR RISK OBSOLESCENCE

TIPS TO HELP YOU ADAPT Adapting is not easy and can be quite costly. Obviously, larger well-capitalized contractors can prepare a plan to increase or maintain their competitive advantage. Larger contractors can also make these changes right the first time because they can hire the technical help they need to implement the changes and educate employees.

ET0719_50-52_RuntheBiz_CB.indd 50

Smaller contractors fall into a high-risk category when it comes to making these types of changes. If they do not implement and train correctly, the result could be wasted front-end cost, as well as procedures being less efficient than they were before the changes were made.

Let’s think about how smaller contractors should handle this “adapt or become obsolete” issue. First, consider the two main challenges that caused the demise of many of the 1955 Top 500. They got too big and slow to adapt. So, you start your adapt process by making your company both nimble and quick when it comes to making changes. More specifically, I would: ˜˜ Clean up the balance sheet and long-term obligations: What this really says is rent more and sell off what you can readily rent.

This also applies to long-term leases. Renting removes a lot of pain and transfers risk to a company that is geared to both own and maintain equipment. Cleaning up the balance sheet and debt obligations frees up cash and borrowing power should you need it to finance technology improvements. ˜˜ Select technology that can tell you what you’re doing on every job every day: You cannot wait until next month or when the job is finalized to figure out if you made money or not. You need operating data, as well as maintenance information to keep downtime to a minimum.

I cannot emphasize enough the need for two or three twenty-somethings familiar with computers, the Internet and apps. You will be amazed at what they can turn out compared to those pushing paper around, and how comfortable they are with learning a new system and passing on that knowledge to us “dinosaurs.” ˜˜ Consult with peers regarding other forms of technology: I have mentioned performance groups before, and they are needed now more than ever. Also attend industry meetings, Association of Equipment Management Professional (AEMP) events, etc., and consider one of the George Hedley Boot Camps. You not only learn, but can meet owners of similar companies you can communicate with going forward. What better way to investigate new technology or systems for your business? But to get the most out of these programs, the CEO of your company must attend and decide what to implement. ˜˜ Prepare incentive plans you can manage to retain and attract qualified help: If you cut costs, free up cash flow, find technology to help manage business on a daily basis and get current industry data by attending peer group meetings, and then use this information to incentivize your employees, you are well on your way to being in the top 25% of those contractors with a competitive advantage. ET

OF THE TOP 500 COMPANIES IN 1955, HOW MANY ARE LEFT TODAY? THE ANSWER IS 50 — OR JUST 10%

There is no doubt that every company out there must adapt or become obsolete. You come across this every time you read an industry publication or a business journal. Disruption is taking place at a faster and faster pace.

I started thinking about the “adapt or become obsolete” issue while listening to a radio show where the host asked: “Of the Top 500 companies in 1955, how many are left today?” The answer is 10%; only 50 of the Top 500 remain in business today.

Think about that. These were major companies with unlimited resources, qualified employees and a meaningful customer list — and they went out of business or had their products/ services replaced by a cheaper, more efficient venue.

How can this happen when these companies had all that horsepower to help them adapt to the changes in their markets? I can make a guess: probably too much overhead and fixed costs to cover while trying to both operate the current business and at the same time transition into new business plans. My second guess would be the size of the organizations made them too slow to adapt before they ran out of money.

Where does this leave contractors who are part of this paradigm shift that is impacting all industries? Right in the middle of it, just like everybody else. In other words, if you are doing things the same way you were 10 years ago, you need to take steps now to adapt or find yourself on the outside looking in.
