A common adage in the concrete industry is that the Hoover Dam is stronger today than it was yesterday. The hydration process continues in perpetuity if both water and un-hydrated cement are present, helping concrete to continually gain strength over time. The Hoover Dam was a gigantic concrete pour and if additional curing is occurring it would be deep within its mass. However, it is likely that additional strength gain after many years is infinitesimally small and thus difficult to quantify.

S ometimes as humans we seek to slow things down, like the The setting of concrete can be described with many terms, including final days of a vacation.

There are also instances hydration. The C3S in the cement continues to react, and the concrete where manufacturers might want to pause the hydration process gains strength as CSH continues to form.

gain and workability. One such technology involves using seeding crystals to provide nucleation sites for hydration products. Recently introduced to the North American market is a product that uses CSH seeds. Nanoparticles consisting of synthetically produced crystalline CSH are added to provide sites for nucleation of hydrated product. This results in early and late strength gain due to improved hydration. The addition of nucleation sites is referred to as “seeding” and is showing promising results in many studies.1 The use of CSH seeds can also reportedly permit reductions in total cementitious content, which can contribute to a lower environmental impact. SPEEDING UP TO SLOW DOWN Thanks to the many admixture suppliers to the industry, precasters have access to a wide assortment of amazing products that can fit any condition, resulting in a high-quality product. Some may avoid considering the use of these products for fear of increasing initial costs per yard, but a consultation with an admixture specialist may reveal that that the long-term costs and benefits outweigh the initial investment.

TECHNICALLY Speaking Beryllium Safety: THE BASICS There are several steps precasters must take to protect workers from beryllium exposure and comply with OSHA’s final rule. By Mason Nichols I n 2018, the Occupational Safety and Health Administration began enforcing a new permissible exposure limit (PEL) for crystalline silica.1 The revised limit was well publicized as it halved the PEL from 100 micrograms per cubic meter (μg/m3) to 50 μg/m3. However, an equally important OSHA final rule also went into effect in 2018 with less fanfare. Beryllium, a lightweight metal that is most often used in the aerospace, electronics, energy and telecommunications industries, is also present in precast concrete operations.2 At a precast plant, multiple steps in the production process can lead to beryllium exposure. OSHA’s final rule reduces the PEL for beryllium by a factor of ten, from 2 μg/ m3 to just 0.2 μg/m3, meaning it’s imperative for precast producers to understand both the operations that can lead to exposure as well as the steps to mitigate or eliminate the issue. EXPOSURE AND HEALTH EFFECTS According to Paul Mellon, director of government and regulatory affairs at Strategic Materials, abrasive blasting is the primary source of potential beryllium exposure at precast plants. Typically, this type of abrasive blasting is used to achieve a specific surface texture, such as on a wall panel or other above-ground piece. However, any time abrasive blasting is performed, including blasting operations used for cleaning forms, the issue can arise. Exposure to trace levels of beryllium is also possible via other work performed at the plant, including welding. Mellon has worked on the beryllium issue directly with OSHA for more than a decade and is considered the NPCA Safety Committee’s 10 PRECAST INC.

Mellon shared that according the process to disperse more readily, significantly to OSHA and safety data sheets, there are two known lowering the danger for both the worker performing the materials commonly used in abrasive blasting that blasting and the cleanup crew.

When complete, this part of the rule will The dangers associated with beryllium – as well as the identify specific approaches, such as ventilation or the means by which it can enter the body – both contribute use of an enclosure, to limit worker exposure. to the call for more stringent Personal Protective For precast plants that do not take the appropriate Equipment (PPE).

MANAGEMENT During Precast University courses, students participate in group activities that drive the NPCA file photo lessons home. Continuing Education Helps Manufacturers Raise the Bar I By providing workplace professional t would be hard to argue with the value of lifelong learning. Whether the goal is to update skills for a specific job, prepare someone for development opportunities, precast a new position or develop a personal interest, the time and effort results in enhanced skills, an expanded knowledge base and greater concrete manufacturers can help personal capabilities. This translates into real gains in the manufacturing reduce employee turnover, improve environment, where both employees and employers experience the benefits. loyalty and enhance the career According to the Society for Human Resource Management (SHRM), 51% of companies offer undergraduate educational assistance and 49% paths of valued team members. provide graduate educational assistance.1 Beyond formal education options, many companies offer training courses, online educational opportunities, certification courses and other ways for their workers to By Bridget McCrea continue their lifelong learning journeys. 12 PRECAST INC.
For employees, continuing education can help fill skills and knowledge gaps, provide information about industry advancements, encourage exploration of new career directions, and polish their resumes for future opportunities. For precasters that offer continuing education opportunities, the rewards come in the form of heightened employee engagement, improved loyalty, better retention and less turnover. FILLING IN THE SKILLS GAPS Whether it’s a recent college grad, a long-time employee or a new executive, everyone can use a little extra education during his or her career. A Texas A&M University study uncovered a growing need for skilled workers in the area of advanced manufacturing, including the use of new technologies and advanced processes to manufacture products of high value.2 The report’s authors note that U.S. government employment data reveals a lack of skilled workers in the manufacturing sector. Additionally, there is concern over the job-readiness of college graduates and the potential gaps in skill sets needed to be successful in an industrial setting, especially in the fields of engineering and manufacturing. At Panhandle Concrete Products in Scottsbluff, Neb., Andrew Hayward, quality and production manager, said the company offers a variety of continuing education opportunities for staff members. The company uses online webinars, meetings and short video clips to help keep employees up to speed on the most important changes in precast processes, industry trends and customer preferences. “We get everyone together in one room, show the videos and then talk together as a group about the topic at hand,” said Hayward, who pauses the presentations at certain points to explain specific topics and brainstorm ideas with the group. “I talk to our employees about their experiences and discuss how this new information and/or the process changes can be applied at our company.” Hayward added that he often turns to educational offerings from the National Precast Concrete Association to round out Panhandle’s continuing education program. Most recently, he used the organization’s content across four different production/safety meetings. He especially enjoys having a large catalogue of online options at his fingertips so they can log on and get the information into practice right away. Hayward loves NPCA’s short, how-to videos, which serve as Precast University classes provide students with knowledge that enhances their careers and benefits their employers.

In return, “The options range from broad topics for entry-level employees to very Panhandle gets a workforce that’s continually evolving and learning. technical topics for veteran workers.” “It’s important to keep on top of the trends and new specifications in the industry,” Hayward said. “We want our employees to know what’s out there, whether it’s a new piece of equipment or a new way to build something. It helps them stay sharp and keeps us ahead of the game.” WALKING THE WALK NPCA member Rosetta Hardscapes of Charlevoix, Mich., highly values continuing education on numerous fronts. The company creates webinars for producers, many of which require help working through common challenges. “We developed a job costing webinar and sent it out to our entire network,” said Rosetta Hardscapes Operations Specialist Aaron Ausen. “We had about 30 executives and sales professionals come to learn best practices on how to cost our products, which showed us that this was NPCA file photo a real issue that attendees needed help with. I’m a big believer in well- rounded continuing education. Andy Hayward of Panhandle Concrete Products not only encourages his employees “(NPCA does) a phenomenal job at not just pulling in business and to participate in continuing education, he also leads by example and completed the Precast University coursework himself and became a Master Precaster at The Precast industry experts, but giving attendees the chance to learn from other Show 2020. folks who have actually ‘walked the walk.’” 14 PRECAST INC.
MEETING YOUNGER GENERATIONS HALFWAY As younger generations of workers make their way into the precast industry, most are looking for different benefits, perks and job experiences. Generations Y and Z both gravitate toward companies that offer ample workplace development opportunities. The proof is in the numbers. According to PricewaterhouseCoopers, the biggest draw for millennials in the workplace is the opportunity for progression (52% of millennials surveyed say this makes an employer an attractive prospect).4 Asked which benefits they would most value from an employer, millennials named training and development and flexible working opportunities over financial benefits. NPCA Vice President of Technical Services and Professional Development Marti Harrell said these and other realities should prompt more manufacturers to develop new or enhance existing continuing education offerings. “Precasters have to meet these younger generations halfway, and one great way to do that is by giving them expanded educational opportunities,” she said. Leadership NPCA is a good starting point for precasters looking to follow Harrell’s advice.5 Meant to sharpen students’ skills and abilities by providing management training, industry association experience and networking opportunities that are vital to successful leadership, LNPCA accepts up to 12 students per year in order to provide meaningful, small-group learning opportunities that will last throughout the participants’ careers. NPCA also offers free “Precast Learning Lab” videos consisting of 5- to 10-minute best practice discussions on specific production practices, sales techniques and marketing approaches.6 Precast University is another option and companies will soon be able to leverage a new onboarding webinar series, which covers everything a new hire needs to know when he or she begins their work. “This will help employees get up to speed very quickly and is particularly relevant for younger generations that may not choose post-secondary education but are already familiar with online learning,” Harrell said. Harrell reminds manufacturers that continuing education can be as simple as playing a short video on safety practices or on a new production concept during weekly, 15-minute team huddles. In other words, it doesn’t take a year-long, formal course to make employees realize that you’re willing to invest in their personal and professional development. In the end, the investment is a win-win as employee development not only benefits the employee as they advance their career, but it helps your company succeed in the future.

But what if there was future specifiers a way to educate these groups on the benefits of precast concrete before they even enter the workforce? and engineers The NPCA Foundation provides scholarships as one way to expose students to the precast industry, but design studios and precast-specific courses have added a new dynamic to bringing can help grow precast to the classroom. your business.

This is our future,’” Clark said. “These are the people designing our products, and we have to do more of this.” Soon, other universities and colleges began reaching out, seeking someone to speak at their classes. “We’re seeing engineering students being exposed to precast concrete that otherwise never would have been exposed,” Clark said. “We’re hearing from the professors that had these things not come along, these students never would’ve learned about precast. To me, that’s shocking, and we have to educate the students who are going to be specifying our products one day.” BENEFITS FOR ALL SIDES No matter where he is presenting, Clark can tell students are starved for more information about precast. “The questions they ask are sometimes questions professionals don’t even ask,” he noted. “They’ll ask something that makes me think more critically.” He’s also seen the benefits of engaging with the people who will one day be specifying precast. “We’ve seen these students call up their professors and say, ‘Hey, I remember taking that class, but I need help. I’m trying to convince one of our senior designers to go precast,’” Clark explained. “That’s powerful. It doesn’t get any better than that.” Photo courtesy of Mustafa Mashal and Idaho State University Ray Clark of Mustafa Mashal, Ph.D., P.E., SECB, CPEng, IntPE(NZ), is an US Formliner uses hands-on associate professor in the department of civil and environmental activities with engineering at Idaho State University, where the NPCA Foundation, Idaho State in conjunction with the PCI Foundation, recently helped sponsor students to bring to life what a precast design studio.

W hen the world emerged from the chaos of World War II in 1945, it was a markedly different place. Some countries found themselves rebuilding both physically and economically, while others were adjusting to redrawn borders or finding their way as newly sovereign nations. But in the U.S., things were looking up. The post-war economy was humming and veterans were putting down roots. One of those veterans, Paul Stein Sr., did exactly that in 1949, moving 90 miles from a small town outside of York, Pa., to the Lehigh Valley to start a small business. Monarch Precast Concrete Corporation in Allentown, Pa., is now run by Paul Sr.’s son, Paul Jr. The company celebrated 70 years in business in 2019. SMALL SHOP, BIG THINKING According to Paul Jr., his dad was self-taught with an “engineering mind.” Although he did not have formal education beyond high school, he learned through reading and experience. In fact, Paul Jr. recently came across a set of small engineering books dating back to the ‘50s that belonged to his father. The construction and concrete industries were not foreign to Paul Sr. After the war, he worked for his brother-in-law as a masonry contractor, and his wife’s relatives were already producing concrete septic tanks near York. However, it was now up to him to succeed on his own. Early on, he was a one-man show, casting and delivering 360-gallon septic tanks by himself. The family – mom, dad, grandma and three kids – lived in a two-bedroom apartment above the shop, so home was where the heart – and the company – were. Over time, Paul Sr. added employees and an outdoor crane, and in the ‘60s he purchased a vacant plant complete with aggregate bins and a mixer. As Paul Jr. thinks back on what his father accomplished in the first few decades, it’s not only the hard work that stands out, but also his dad’s ingenuity. For example, in the ‘60s, manholes were an in-demand product line as municipalities shifted to central sewage. “He started dry-casting manholes,” Paul Jr. said. “He was pretty innovative because nobody else in the area was doing that.” Monarch Precast built its current plant in 2003 to meet increasing demand and has continued that growth pattern. precast.org 21

TOGETHER IS BETTER In addition to equipment and product lines, two key additions were Paul Jr. and his younger brother, John. Paul Jr. had worked summers in high school and joined the company full time in 1974 right after graduating from college with an engineering degree. By that time, the company had grown to nearly 30 employees. He loved working with his dad, who was happy to consider any idea and either encourage it or gently redirect. Together with the employees, the three continued to expand the company’s product lines and customer base. But when the time came to pass the torch, Paul Sr. didn’t hesitate. “My dad rounded up my brother and me, and we went up into the Pocono Mountains to see a job,” Paul Jr. said. “We stopped for lunch, This custom filter box features Fabco filters and a stainless steel filter table. and that’s when my dad made the announcement that he was retiring.

In addition, his “Jill, Joe, and Charles are three of the most dedicated, hard-working tradition of retaining long-term employees is still thriving today. people I have ever met,” said Paul Jr. “That is just to name a few. I There’s Charles Dixon, who Paul Sr. hired in the ‘70s and is still am very fortunate and proud to have so many dedicated long-term driving trucks, and Joe Penchishen, who Paul Jr. says is “one of a kind” employees.” and has been with the company for 50-plus years.

Concrete Association circles is Eric Lasko, a Master Precaster and Leadership NPCA graduate. “When I started here in 1998, I was young, freshly married and didn’t know what I wanted to do,” Lasko said. “I didn’t really know about precast, but once I got into it, I loved it. Every day, it forces you to be at the top of your game, and there’s not a day that I think I don’t want to be doing what I’m doing.” While straightforward in methodology, Paul Jr.’s employee philosophy is admirable in practice. His focus is on listening to people and giving them the opportunity to grow along with the company. From Lasko’s perspective, it all comes down to respect and communication. He said Paul Jr. has emphasized that the way you communicate with someone makes a big difference. Just as Paul Sr. allowed his son to bring any idea to the table, Paul Jr. tells his people there is no such thing as a bad idea. “I have a great mentor in Paul,” he said. “As I look at our employees here, everyone is treated with respect for what they bring to the table. I think that’s why we have the long-term dedication we do.” A Precaster’s Perspective Having graduated from both NPCA’s Production and Quality School and Leadership NPCA program, Monarch Precast "I didn’t really know about precast, but Corporation employee Eric Lasko has a unique perspective on how once I got into it, I loved it. Every day, it the association has helped him grow in his career.

According to Paul Jr., his mom NPCA graduate. and dad would go to the Conventions and were always enthused about the great people. Paul Jr.’s first meeting was in the fall of 1974. “I remember my very first Convention, and there was just a world of knowledge right at our fingertips,” Paul. Jr. said. “It could have been a simple matter like a buckle on a form or seeing information that I wasn’t even aware existed.” Today, the tradition has been passed along to other Monarch employees. Lasko has been to many Precast Shows and has built his own network. He said after a year or two, people know him by face, and soon enough, he earned lifelong friendships. “To me, it’s still a family-oriented industry,” he said. 24 PRECAST INC.

THINKING AHEAD Today, Monarch Precast is thriving. In 2003, the company built a plant based on growth- minded decisions. Manholes and other products manufactured at Monarch Precast can weigh as much as 60,000 pounds per piece, and the new plant has the cranes to handle them. The company’s mindset is, “We can tackle just about anything that’s transportable.” The company has also made a name for itself in the specialty products arena. With an in-house engineer and a knowledgeable and experienced team both in the office and in the plant, Monarch Precast manufactures packaged pumping stations, packaged water meter chambers and a variety of custom products. Paul Jr. also increased the company’s capabilities in the custom market by switching from steel panel forms to aluminum. “The weight aspect for the employees is much less strenuous,” he said. “It was in the interest of safety, productivity and quality. Every year we’re adding some new forms, and a few years ago, we had a job so custom that Precise Forms made some one-off forms just for that specific job.” Another major emphasis is quality control, which has long been a top priority for the company. Paul Jr. said some of the critical factors were batching and mixing. “Our team of dedicated employees realizes the emphasis we put on quality, and they understand the value of customer service.” – Paul Stein Jr., Monarch Precast 26 PRECAST INC.
“We put a brand-new batch plant in that is Monarch Precast provides state-of-the-art,” he said. “Back in the ‘70s, my customers dad replaced our mixer with a TEKA mixer, with complete and when we put the new plant up, we put in a solutions such as this “pre-piped” larger TEKA mixer because they are so reliable. altitude valve We use a combination of different admixtures vault. that are metered into the mix, and depending on specifications, the mix may also include two types of Xypex additives which enhance the watertight properties and corrosion resistance of the product.” Lasko said the focus on quality ensures customers know they can install products with no concerns, an approach that has solidified their relationships. One recent endeavor helped further deepen those relationships. The company participated in NPCA’s inaugural Precast Days event in October 2019, and the return on investment played out right before their eyes. Lasko said they hosted engineers, contractors and individuals from municipalities. “The one common response was, ‘Wow, we didn’t know what it took to make the product’,” he said. “For the guys who see the end product, to hear them say that is wonderful. Engineers learned more about the precast industry, and we are working one-on-one with them on certain products, so it really ties all of us together working as one.” “What I saw here as the owner of the company also was the enthusiasm among the employees, who were excited about doing something like this,” Paul Jr. added. THE RIGHT WAY Carrying the growth mindset and employee focus into the future, Paul Jr. sees a lot of good yet to come for the company his father built seven decades ago. He has always been cautious to grow in logical precast.org 27
“We have the formula. If the wheel isn’t broken, don’t fix it. Make it better.” – Eric Lasko, Monarch Precast; NPCA Master Precaster & Leadership NPCA Graduate ways. Rather than adding a product line just to add it, he focuses on enhancing current lines, which will continue to be the case. Lasko appreciates this focus. “We have the formula,” he said. “If the wheel isn’t broken, don’t fix it. Make it better.” For Paul Jr., the success is sweeter because the employees he cares so much for are succeeding right alongside the company. “Our team of dedicated employees realizes the emphasis we put on quality, and they understand the value of customer service,” he said. “That’s what makes us unique and has given us the success that we have. I enjoy helping them see their potential; to give them the realization that they have a future with the company and a vested interest in the company.” PI Kirk Stelsel, CAE, is NPCA’s vice president of communication & public affairs. 28 PRECAST INC.

GREEN PIECE The Seven Wastes Waste #4: Waiting Waste By Shari Held Editor’s Note: This is the fourth article in a year-long series about how seven common types of waste in manufacturing can create unprofitable activity and how to address them in your plant. I t’s a sight precast plant owners and managers dread – seeing workers waiting around. The reasons for wasted time are many: workers don’t have what they need, employees need clarification on a process before being able to proceed or a machine is either down or in such high demand that team members must take turns. Whatever the cause, waiting creates a bottleneck in the process and it’s costing you time and money. WAITING WASTE IN PRACTICE When Henry Ford put the assembly line concept into action, he was addressing one of the seven wastes lean manufacturing works to reduce or eliminate. When there is a steady flow down the line, nobody is NPCA file photo waiting around and any inaction is obvious because it impacts those before and after you in a domino-like effect. Wade Pink, president of Pink Precast in Dorchester, Ontario, identified three things that contribute to the majority of waiting time for his company: waiting for the overhead crane to become available, waiting for the mixer and waiting for the concrete bucket to return to the production area to pour the next forms. Earlier this year, the company expanded its plant, making it three times its original size. Today, it’s one long building with the mixer located in the front third of the facility. This creates a long distance between the mixer and crew at the other end of the plant. Optimizing the plant layout for efficiency is essential for decreasing waiting waste. “We knew when we expanded that we’d have a bit of a challenge because of the distance we were ending When working on high-volume products, it’s important employees have an efficient system from prepping a form to placing product NPCA file photo into the yard or onto a waiting truck. 30 PRECAST INC.
