EPD and the Aggregate Industry:
Partnering to Keep Georgia Great
By Richard E. Dunn | Director | Georgia Environmental Protection Division he aggregate industry is no stranger to cooperation and mutually beneficial partnerships, as this industry provides materials for multiple processes and products. The same can be said for the Georgia Environmental Protection Division (EPD). In fact, it’s a key tenant in the mission statement: “We take the lead in ensuring clean air, water, and land. With our partners, we pursue a sustainable environment that provides a foundation for a vibrant economy and healthy communities.” For EPD, building and maintaining strong partnerships allow us to more effectively address new or emerging issues, build more flexibility in how regulated firms achieve performance goals, and helps to ensure our requirements complement rather than compete with the way business decisions are made in today’s economy. The current partnership between Georgia’s EPD and the aggregate industry shows what can be achieved when we work together.

In the last year, EPD’s Surface Mining Unit in the Land Protection Branch, in coordination with the Georgia Construction Aggregate Association (GCAA) and the Georgia Mining Association (GMA), held environmental education workshops throughout the state. More than 100 representatives from industry, consulting, and municipalities attended “Surface Mining 101.” The workshops included presentations from the Surface Mining Unit; the Stormwater Unit and the Industrial Permitting Unit from the Watershed Protection Branch; and the Stationary Source Permitting Program from the Air Protection Branch. Each program highlighted specific topics important to the industry, provided clear direction for permitting and compliance requirements, as well as answered questions and discussed topics of importance to both sides. The Surface Mining Unit continues to coordinate and communicate with the mineral extraction industry to find solutions that maintain the high standards for the protection and use of the land and are econom-

ically viable. Coordination and assistance are key elements for timely permit issuances and compliance assurance for the EPD Watershed Protection Branch Industrial Wastewater and Stormwater Units. Many aggregate industries facilities have coverage under at least one National Pollutant Discharge Elimination System (NPDES) permit. In 2016, in partnership with the GCAA and the GMA, the Industrial Permitting Unit issued a general NPDES direct discharge permit for Mining and Processing Facilities, encompassing the aggregate industry and associated industry groups; including asphalt, concrete and ready mix. The ability to apply for coverage under a general permit decreases the administrative time required for obtaining an NPDES permit allowing the industry to re-
main competitive and focus their resources. The industry continues to focus on sustainability and recycles much of the water used onsite to reduce the need for water withdrawals and subsequent discharges. The Stormwater Unit has a new compliance assistance initiative. During and after the state-wide Industrial Stormwater General Permit reissuance in 2017, the Stormwater Unit reviewed historical data to get a snapshot of common questions, issues, and concerns across the regulated community. By tracking the notices of intent (NOIs) for coverage, the Stormwater Unit identified the largest industrial sectors in Georgia with coverage under the Industrial Stormwater General Permit. The aggregate industry and associated products are well represented: Glass, Clay,
Cement, Concrete, and Gypsum Products (Industrial Stormwater General Permit Sector E) is the 2nd largest sector; Mining and Dressing (Industrial Stormwater General Permit Sector J) is the 4th largest sector; and Asphalt Paving and Roofing Materials (Industrial Stormwater General Permit Sector D) is the 10th largest sector. With this knowledge, the Unit plans to continue the work started with the “Surface Mining 101� and develop specific assistance regarding permit coverage and compliance. The program has started building coordination efforts with industry trade groups to help disseminate relevant information and solicit feedback and comments from industry as well. In the Air Protection Branch,

there have been several small but significant changes to assist the aggregate extraction industry. The Branch has worked to create clearer guidance in regard to emissions from processing equipment, as well as modeling of dust/particulate emissions. The Air Branch created a special permitting exemption that allows for the replacement of parts of certain equipment that wear and need frequent replacement as a cumulative modification instead of requiring an application to modify the permit each time. This greatly reduces equipment downtime while waiting on permit approval. The air emission factor for paved haul roads was updated by EPA to reflect that dust emissions are lower than previously estimated. Capturing this reduction in estimated emissions may allow for higher permitted production

before triggering emission threshold levels. Also, within the last year, the Branch spearheaded research to allow for the creating of EPD guidance that all portable generators, regardless of the intended use, no longer require permitting as if they are stationary sources. Previously, this exemption was available only to generators for emergency use. This change will be welcomed by many in the industry. As time and progress continue to move forward, so does the Georgia EPD. The Division is developing an all-inclusive online permitting application and reporting system, the Georgia EPD Online System (GEOS). This system currently houses many application and reporting capabilities, but ultimately it will be the onestop site for all Land, Air, and Water applications. GEOS also
tracks and relays progress as staff reviews applications and develops permits. It also provides increased transparency by providing important documents and material for the public to view. Protection of our environment and profitable businesses are not mutually exclusive goals; in fact, having both is the only goal worthy of Georgia citizens. When we partner together, lending EPD’s regulatory experience and knowledge to the business acumen of our aggregate industry counterparts, we create a scenario containing the best information with which to make the best decisions. Citizens see businesses endeavoring to make not only products and services that make Georgia great, but preserving the environment, allowing generations to enjoy the resources with which we’ve been blessed. v

Construction Dollars + Sense By Al Clark | Smith, Adcock and Company LLP
Briefly: The new tax law has a special calculation based on 20% of business income, with some limitations. Now is the time to structure out the limitations.
he Tax Cuts and Jobs Act (TCJA) has a new 20% deduction for non-C corporation businesses. It is earned at the company level and computed on the personal tax return. It applies to most construction businesses for 2018. The new deduction is Section 199A of the tax Code. It is similar to the prior Section 199 Domestic Production Deduction, which ended in 2017, but with extensive rules on calculations, limitations, phaseouts, carry-overs, and application. It does not apply to specific businesses, including medicine, law, and consulting but should apply to all construction including architecture and engineering. While some design / build can appear to be consulting, it is not disqualifying for purposes of this deduction. The purpose of the new deduction is to give a rate reduction to passthroughs since C corporations had their top rate reduced from 35% to 21%. This 199A deduction makes the new top rate of 37% for individual returns an effective rate of 29.6% for the business income (37% x 80% = 29.6%) on an individual return.
T
One of the limitations for current focus before the end of the year is the wage requirement. Wages of at least 50% of the deduction amount are required. This can be a limiting factor for the small sole proprietor who self performs all its work and pays no wages, or the general contractor who subs all the production with very little in actual wages paid directly from the business. Now is the time to evaluate the expected 199A deduction and restructure sufficient wages to maximize the deduction for 2018. At the individual tax return level, the pass-through income, along with the other income of the owner, can be under $315,000 on a joint return and not have the 50% wage rule as a limiting calculation. But there is a phase-out calculation, and above $415,000, the 50% wage calculation is fully limiting But just increasing wages may
not work well in all cases. There are operational restrictions against artificially changing subs from independent contractors to employees receiving a W-2 for wages. And the owner of an S corporation needs to closely calculate the cost of the additional payroll taxes for his increased wages compared to the benefit of the new 20% deduction. Perhaps a more common situation is the S corporation which may be paying higher compensation to the owners than is necessary and thereby reducing the available 20% deduction. Reasonable compensation to owners of S corporations is required by the IRS rules, but “reasonable� is not defined. Consider, for example, a group of S corporation owners with combined W-2 wages of $500,000 who can reduce that to $400,000, and at the same time increase their distributions by a similar amount. Since compensation is a company deduction while distributions are not, this restructure of cash flow from the company to the owners just increased the Section 199A deduction by $20,000 ($100,000 x 20%). v

City of Atlanta Department of Watershed Management Transforms Dormant Quarry into Major Water Resource By Ade Abon | Project Director | City of Atlanta
tlanta - Bellwood Quarry, located in Westside Atlanta, has a history that spans 100 years. In its heyday, the granite mined from the quarry was used for paving city roads and sidewalks, as well as its buildings. Today, the former Bellwood Quarry serves as the focus of Atlanta’s $342 million Water Supply Program (WSP). Funded in the Department of Watershed’s five-year $1.26 billion Capital Improvement Program, this investment in revitalizing the City of Atlanta’s aging infrastructure will extend the City’s emergency water reserves from three days to 30 days or more. The increase in raw water reserves will prove crucial if ever the City experiences a day without water from the Chattahoochee River—its only source of water. A study commissioned by City of Atlanta Department of Watershed Management (DWM) discovered that if the Atlanta service area were to experience a day without water, it would cause an economic impact of $250 million a day, and a week without water would have approximately $1.2 billion of economic impact. Work on repurposing the quarry, located in the heart of the city, began in September 2016 when the 400-foot long tunnel

boring machine (TBM) which, after a citywide naming contest, is now called “Driller Mike,” began drilling a five-mile tunnel to connect the Chattahoochee River to the Hemphill and Chattahoochee Water Treatment Plants, and the former Bellwood Quarry. After two years of drilling through granite rock approximately 26,400 feet underground, TBM “Driller Mike” completed the fivemile tunnel on October 4, 2018, which coincided with the nationwide Imagine A Day Without Water awareness campaign, led by the US Water Alliance. The next phase of completing the capital project is now underway. Crews are cleaning and lin-
12
ing the interior of the tunnel with one-foot thick cast-in-place concrete liner. The concrete liner mix will consist of water, cement, sand and gravel, and the concrete will be placed using both surface and underground concrete pumps. A modified contact grouting program will be conducted to fill the voids behind the permanent concrete lining and reduce the inflow of groundwater into the tunnel. When completed in December 2019, the Water Supply Program will connect two water treatment plants, two pump stations and the Chattahoochee River to the new reservoir at the quarry. In addition, the four verti-
cal turbine pumps at the Hemphill Water Treatment Plant will withdraw water from the tunnel for treatment. In addition to serving as a major water resource, the land surrounding the reservoir is slated to become Atlanta’s largest public park, complete with hiking trails, baseball fields and an outdoor theatre. The Water Supply Program serves as a critical component of Atlanta’s sustainable water future, impacting approximately 5,000 jobs and preventing $250 million dollars per day in economic impact each day the City is without
water. v

Changing Times, Changing Knowledge and Roles for Lifetime Learning
By Nelson C. Baker, Ph.D. | Dean | Georgia Tech Professional Education
e live in constantly changing times. As our world evolves, so must the way we learn and work. The drivers of change are not specific to an industry or profession but to our society as a whole. It starts from early education, and kids are growing up with skills we, as adults, learned not much more than a decade ago. Today’s children, from kindergarten all the way though high school, are digital natives who instinctively know how to use technology in their daily lives. The products they create and seek along with their capabilities in the workforce will be very different from the employees of today. When it comes to demographics, significant shifts are taking place. Traditionally, universities have been serving students aged 18 to 24. However, the number of 18year-olds is shrinking and fewer of them are interested in STEM as a field of study or a future career. Perhaps one of the main reasons for this declining interest is the perception that STEM is too challenging or doesn’t connect with their passions. Additionally, the number of high school graduates
W

choosing to attend college is decreasing because of the high costs of higher education. On the other hand, people are living longer. This increase in lifespan leads to a change in social norms and how long we need to work to be able to afford a comfortable and distinctly longer life than our parents or grandparents. These demographic changes signal a need for higher education to serve a wider audience. As public universities, we need to serve all the citizens of our state and no longer focus mainly on the 18 to 24-year-old group as we have done in the past, especially as new knowledge and technologies impact the work we do. New knowledge is being created at a pace with which we can barely keep up. And it’s perpetually expanding. To remain current, today’s workers need to constantly update their knowledge and skills. For example, mobile devices that we rely on so heavily in our dayto-day lives have existed for less than 15 years. If you graduated more than 15 years ago and have not stayed current in your field, you’d need to consider professional education to get up to date. Since technology and the digitization of processes has affected all professions, we all need to continue learning to keep up with our fields. This is why universities need to evolve to be able to serve the learning
needs of the entire workforce and not focus primarily on building an entry-level workforce. The change in the nature of work demands new capabilities. Today’s workplaces need agile thinkers who can keep up with technology and navigate the changes it brings to their fields. In addition, they need to be T-shaped thinkers who have deep expertise required for their areas of specialization but also social breadth and the ability to collaborate and make connections across disciplines. In addition, digital skills are essential. Embracing change is not an option. It’s imperative for the survival of our professions, industries, organizations, and jobs. Countless examples exist of organizations that didn’t heed the calls for change and no longer exist today. From the media industries to retail establishments to the very nature of all work, people and organizations are changing. The market is volatile, and even established companies that are seemingly fail-proof can cease to exist if they don’t evolve. In 1964 for example, the average tenure of a company on the S&P 500 was 33 years. By 2016, it dropped to 24 years and is forecast to be 12 years by 2027. In 10 years, as predicted by Innosight, it is estimated that 50 percent of the S&P 500 will be replaced. Jobs change as the nature of Georgia Contractor
work changes. Today’s average worker changes jobs between 10 and 15 times in a career according to the US Department of Labor. Sixty-five percent of today’s schoolchildren will be employed in jobs that haven’t been created yet. And by 2030, half of today’s jobs will disappear. These changes have been on our minds at Georgia Tech, so we created a commission of faculty, students, and staff to study this evolution in depth and to create a roadmap for higher education for the future. One of our key realizations is that we need to be deliberate in our innovation. We need to drive how and when we change and, most importantly, for whom we change. Our new vision includes initiatives that enable us to serve our community from kindergarten to forever. Making this commitment a reality will require sweeping changes in the way higher education has operated for centuries. For example, we intend to break down the artificial barriers between conventional schooling and higher education to enable learners of all ages to connect with us and to benefit from our offerings whenever they need us. Another change is allowing flexible academic calendars and easily accessible pathways through Georgia Tech without compromising the rigor and quality of our education. This way, we can serve learners of different ages with different types of learning products at different times in their lives. In addition to the traditional degrees we’ve been awarding for decades, we’ll be recognizing the January | February 2019
different types of learning people do throughout their careers with new credentials that are sought after and valued by employers. Networks are essential to learning since it doesn’t happen in a vacuum. We already serve thousands of learners worldwide with our online degrees. Our next step is to strengthen our network across the globe to enable our learners to better connect with us and each other. Finally, we intend to provide advising and coaching for life to our community of learners. Many choices and pathways exist for people of all ages who want to keep learning. They need expert advice to navigate their options and make the right decisions about their education. We believe it is the duty of a public university, as a trusted member of society, to offer this kind of service to its community. Admittedly, this university of the future is a bold new vision
fraught with challenges. To realize it, we need to break down silos and find ways to penetrate longestablished barriers so that we can continue to innovate. This vision to educate our community includes educating ourselves, which means training our own employees for tomorrow. As a higher education institution, we’ll need to reflect on the policies that prevent us from being innovative and realizing our unconventional goals. The road ahead is not without its obstacles, but we’re crystal clear on where we’re headed and why we must move forward regardless of the challenges ahead. Change is inevitable, and succeeding now and in the future means learning throughout our lives. As a public university, it is our duty to provide the learning opportunities and services our community needs to be able to thrive during times of change. v

This location is meaningful as China has had to cope with increasing space-scarcity issues and while innovative projects are born to reshape cities of tomorrow, primary needs still concern major infrastructure with a strong focus on massive rail transportation projects and energy transportation. Vice-President of the ITA, Jinxiu (Jenny) Yan highlighted the increasing role of subterranean spaces in China for 40 years: “Although the uncertainty of geology and complex environment China completed 45.000 km of tunnels over the past 40 years. One of the main issue for China is also the
construction of tunnels in high altitude. The Sichuan-Tibet Railway, a mega future project is also one of the most challenging as it has to cope with a freezing environment. Through eight categories and 1 Lifetime Achievement Award, the ITA Tunnelling Awards identifies and reward major disruptive innovations and groundbreaking projects. This edition, the event took place in Chuzhou, November the 7th, following the 20th CTUC conference (Chinese Tunnels and Underground Works Conference).

€500M) - The Immersed Tunnel of the Hong Kong-ZhuhaiMacao Bridge Link China
It has taken eight years to create this 6.7 km tunnel, immersed on 5.6 km, connecting the cities of Hong-Kong, Zhuhai and Macao. The tunnel was assembled with 33 elements of 180m in length, 11,4m in height and 37,95m in width, for a weight of 80.000 tons. Those are the world’s largest tunnel elements. Artificial islands have been created at the both ends of the tunnel to connect it to the bridges. This bridge link is 45m under the sea, to allow passage of 300,000 DWT tankers. This is one of the deepest immersed tunnels in the world. Some innovative techniques have been used to build this tunnel. Due to delicate geological conditions, the foundations of the immersed tunnel have been mixed between rigid and soft ones. This resulted in the use of Pre-stressed High Strength Concrete piles, Jet grouting piles, Sand Compaction Piles, Compacted Block Stone plus Gravel Bed Foundation to create optimum foundation conditions. This is also the first tunnel in the world where curved tunnel elements have been prefabricated, improving many technologies to measure what size was necessary. To conclude, the final section of the immersed tunnel, the so-called closure joint is an innovation in a “V shape” and of a sandwich structure (steel box structure filled with high fluid concrete) as the
• Project of the Year (between
€50M and €500M) The Queershan Tunnel on National Road 317 – China The Queershan Tunnel on National Road 317 was a key construction project in China. It extends from location of the sandaoban of G317 to location of the liudaoban. In Sept., 2017, after 10 years of repeated scheme demonstration and five years of hard construction, the Queershan Tunnel on G317 went into operation. The Queershan Tunnel conquered a number of technical problems in construction in the high altitude and cold regions of plateau and broke the natural barrier on the northern line of the Sichuan-Tibet Highway, which will further close the link between the mainland and Tibet and help accelerate economic and social development in Tibetan region. It cost €150 million. The tunnel was completed on schedule, 100% good quality rate was reached, and no casualty occurred in construction. Queershan Tunnel completely changes the traffic in Queershan section, which will not be blocked by snow and ice in winter since then, ensuring G317 safe and unblocked throughout the year.
• Project of the Year incl. Reno-
vation (up to €50M) : Construction underneath the Operating Railways - Iran This project named Zarbalizadeh shallow tunnel construction underneath the operating railways. The purpose of this project is to construct the Zarbalizadeh un17
derpass in the 16th district of Tehran, which is the East-West connection between two urban areas and lead to reduce the traffic and travel time in this dense and populated demographic region. The project has been constructed by going under the subway line of Tehran Metro Line 1 with three minutes headway time and 550,000 daily commuters, and the North-South Railway with transportation of 40,000 passengers and a hundred tons of goods per day. This project is located between the South Passenger Terminal and two Tehran's subway stations. The date of completion of tunnelling civil works is June, 2017, and the overall cost is €6.5 millions.
• Technical Project Innovation
of the year - A Mechanized Method with Large Section Horseshoe Shape EPB-TBM First Applied in Loess Mountain Tunnel - China This project is a mechanized method with large section horseshoe shape EPB-TBM first applied in loess mountain tunnel. For mountain tunnel in loess, the con18
ventional tunneling method is to use the sequential excavation method and double lining. The horseshoe shape multiple cutter heads EPB-TBM method have been made to replace the traditional one. Safe and fast, this new method guarantees the quality of construction and the working environment. Compared with single circular cutter head EPB-TBM, newly developed horseshoe shape EPB-TBM with multiple cutter heads could reduce manufacture cost of the TBM, increase utilization ratio of the section, and reduce the quantity of excavation and construction material. The project has developed the world first large horseshoe section (10.95m height and 11.9m width) EPB-TBM with multiple cutter heads. This project last 441 days (Nov. 11th, 2016 - Jan. 26th, 2018) and cost overall 60 million euros.
• Technical Product/Equipment Innovation of the year - Multifunctional Energy-Storage and Luminescent Material for Sustainable and Energy-saving Lighting for Tunnels - China
This project deals with a multfunctional energy-storage and luminescent material (LUMA) for sustainable and energy-saving lighting for tunnels. It is featured by energy storage, delayed luminescence, release of negative oxygen ions, dirt resistance, self-cleaning and antistaticity. LUMA has been applied in manufacturing a series of products including tunnel coating, tunnel reflective aura, delineator, raised pavement marker and road marking. It fulfils “safety, comfort, environmental friendly, and energy efficient” requirement simultaneously for tunnel decoration and lighting. LUMA are innovative products which promote the technological advance of energy saving, safety and disaster prevention in road tunnels. LUMA is novel and unique, and has many functions such as non-flammable, energy storage, delayed luminescence, negative oxygen ion release, anti-mildew, anti-corrosion, anti-pollution, self-cleaning and other functions. Since 2016, it was estimated that LUMA helped to save 22 million RMB of energy cost. LUMA significantly reduces the energy consumption in tunnel lighting. It alleviates contamination to tunnel walls from car exhaust increases the visibility and air quality in tunnel, and provides illumination for escaping from accidents. LUMA have been used in road construction of China and was recommended for application in the national traffic system. They can be applied in underground engineering for energy saving and disaster prevention by providing emergency lighting. Georgia Contractor
• Innovative Underground Space
Concept of the year - Norwegian Rock Blasting Museum – Norway The Norwegian Rock Blasting Museum is an underground museum located near the Olympic City of Lillehammer in Norway. The museum was created 25 years ago by the main stakeholders of the industry, to recognize Norway’s close and extensive history with tunnels. The Norwegian Rock Blasting Museum is an entertaining and informative journey through the history of Norwegian tunnelling and rock blasting, with a 240 m long semi-circular tunnel as the main attraction. The tunnel display equipment and tunnelling techniques date from the beginnings of tunnelling all the way to modern computerised drilling and TBM boring. This is a unique museum, and possibly the only purpose-built "tunnelling museum" in the world.
• Safety Initiative of the Year -

Contribution of Aggregates to Concrete Pavements
By Les H. White, PE | Paving Solutions Engineer | Cemex - Ready Mix USA, Atlanta Division ggregates have been a critical component of concrete paving since construction of the first concrete road in the U.S. in Bellafontaine, Ohio, in 1891. As a constituent, aggregates typically make up a large percentage (60% - 75%) of a concrete paving mix. Aggregate sizes are normally categorized as coarse, ranging from material retained on a No. 4 sieve (3/16 in.) up to a maximum of 1 ½ in, and fine, which is material passing a No. 4 sieve. Aggregate gradation is the
A

mix of fine and coarse aggregates that adds stability to a concrete mixture by allowing more space to be filled with stone than with the water and cement paste that typically makes up the remainder of that concrete mix. In a standard concrete mix used for paving, as well as other applications, the aggregate components may be defined as sand for fine aggregates and #57 stone, for example, as the coarse aggregate. Coarse aggregates may vary from place to place depending on
Figure 1 material availability. In this example, the #57 stone is defined by a range of particle sizes from 1 in. down to material retained on a No. 4 sieve. When combined with the sand, you get a matrix that looks like the one shown in Figure 1. An intermediate aggregate size can also be added to a mix to increase Georgia Contractor

the performance of a pavement and make more efficient use of all the concrete constituents. One example of this can be found in Roller Compacted Concrete. Roller Compacted Concrete (RCC) is a no-slump concrete that is placed by an asphalt-type paver using a standard or high-density screed. By adding an intermediate sized aggregate and adjusting the amount of fine and coarse aggregate, the amount of cement and water is reduced. This leaves a mix that is dry enough to be hauled by a dump truck rather than a typical concrete mixer. Figure 2 shows a typical RCC mix. At the other end of the spectrum are mixes that are not well-graded and make use of a single aggregate size. One such mix is Pervious concrete. Pervious concrete uses a single sized aggregate with cement and a low water content to create a mix with void space ranging from 15% - 25% as shown in Figure 3. When used as a pavement, pervious concrete functions as a component of the stormwater management systems. The void space allows rainfall runoff to infiltrate into a reservoir layer beneath the pavement and be retained onsite which, in addition to reducing the volume of water leaving the January | February 2019
site, helps to address water quality concerns. The reservoir layer, or subbase, is commonly made up of loosely compacted aggregate, such as #57 stone, with a void space of 30%-40% allowing for temporary water storage. The final contribution of aggregates in a pavement system that we will look at is in the role of subbase. A thick stone subbase is not intended to reduce the thickness of concrete in a paving section. The amount of stone necessary to create a support platform suitable for a reduction in concrete thick-
Figure 3 ness would not provide an economical pavement design. As mentioned above, in a pervious
pavement system, the aggregate subbase is loosely compacted and provides storage for rainfall runoff. In other pavement systems, the aggregate subbase in often more densely graded and compacted to provide a uniform platform to build the pavement on and a layer of protection against pumping of erodible soils under frequent, heavy wheel loads. Aggregate subbases can be as thin as 4 inches to help resist pumping of subgrade soils. Thicker subbases are controlled by factors such as site access during construction, onsite soil conditions, and the anticipated volume of high speed, heavy vehicular traffic loading. From and economic perspective, aggregate sizes, such as #57 stone, referenced here represent the most commonly available materials in the market and offer the most cost-effective mix designs for concrete pavements. Deviations from the use of standard materials in size, type, or quantity can be expected to result in higher costs for concrete mixes and less economically feasible pavement solutions. v

Fixing the funding mechanics of the Highway Trust Fund and improving our aging roads will allow goods and services to move faster and safer, create jobs and allow people to travel to work more safely. When you do all of that, our economy can grow.” said Michael W. Johnson, NSSGA president and CEO. “That is why we encourage all lawmakers to work together, because better infrastructure leads to a better America.” A Democratic majority in the House could mean additional hearings for committees with oversight of the Mine Safety and Health Administration and Environmental Protection Agency. Johnson explained that people from aggregates companies have an opportunity to educate about the importance of aggregates and the costs of overly-burdensome regulations. “In September, hundreds of people came to D.C. to show lawmakers the ways that many regulations, which are not based on common sense or sound science, delay or derail critical infrastructure improvements. We have an opportunity, as an industry, to keep making our voice heard loud and clear on Capitol Hill this year.”v Georgia Contractor
Profits, Projects & Pressure: 2019 will see many construction companies
managing projects digitally for the first time By Kenny Ingram: IFS Global Industry Director for Engineering, Construction & Infrastructure will see a digital leap forward as many construction companies explore implementing integrated business software into projects for the very first time. Tighter margins, global skills shortages and new industry entrants are all ramping up the pressure on traditional construction businesses to deliver greater productivity and more integrated, cost-efficient projects, on time, every time.
with housing shortages a key driver. The UN estimates that over 2 billion new homes will need to be built over the next two years. Modular manufacturing enables affordable houses to be built faster and at higher volume. Driven by a worldwide shortage in skills and housing, increased modular construction will impact the construction industry massively in 2019.
Prediction #1: 50% of all construc-
already seeing a wave of new entrants coming into the industry. Take that modular housing factory
2019
tion projects worldwide will include modular content by 2022, driven by the growing global skills shortage In March 2018, a new factory opened outside Liverpool, England employing 150 people 24 hours a day. What does it manufacture? Homes—starting with a first order of 81 homes and 58 apartments, as part of a first-year target of 450 homes. And it’s just one among many. At IFS, in 2018 we had four times greater customer activity around modular construction than in any previous year. From schools in Ireland to prisons and hospitals in the United States; from sustainable luxury apartments to vast workers’ dormitories, 2018 has seen modular construction go well beyond hype. In 2019 it will get even stronger, January | February 2019
New entrants will make agility even more essential - For a start, we’re
in Liverpool. Neither of the two founders came from the construction industry. One, Luke Barnes, was a design engineer, his partner a software engineer. Barnes told reporters: “I found there was a big gap in the market as there were no constructors that offered the quality, deliverability and competitive pricing I was searching for.” 2019 will see growing numbers of traditional construction companies begin opening modular factories to stay competitive. And more new players enter the industry— from manufacturing, supply chain and logistics, to local governments, banks and insurance companies. Many will be able to offer flexible finance and service packages too. The pressure on incumbent building firms to adapt will be huge. They’ll need tighter control and more adaptability over every aspect of their projects. Proving they can, if necessary, partner up with larger networks of suppliers,
23
offer services and maintenance on assets once built, include equipment hire, and yes, even offer or manufacture some modular units or components. It all adds up to an urgent need for better, more integrated digital management of complex, demanding projects. That need is driving my second industry prediction. Prediction #2: In 2019 more con-
struction companies than ever before will start trying out integrated business software—for the very first time 10% of traditional construction firms could go out of business over the next five years. Competition around delivery and productivity will be fierce. Many companies will find themselves balanced on a knife-edge of opportunity: On the one hand growing urban populations and housing shortages will mean more demand and a higher order intake. On the other, shrinking profit margins and increased competition will mean unprecedented pressure on productivity and delivery. As a result, 2019 will see more firms moving from being document-driven to data-driven. Many will take their first steps into digital, and make their first investments in integrated business systems like Enterprise Resource Planning, or ERP. Two main drivers will turn integrated business systems like ERP from a nice-to-have into a need-to-have. When more is less: Growing pressure on margins - With profit
margins as tight as they are, many construction firms feel as if the more business they bring in—the 24
less money they make. A recent report found that Deloitte construction companies’ profit margins are under pressure in several European submarkets, with Western Europe particularly vulnerable. In the UK, Belgium, the Netherlands, and Ireland profit margins are so narrow they may not even be offset by higher order intake. 31% of the UK’s largest contractors reported a fall in margins in November 2017, with the country’s largest 10 contractors having a negative average margin of -0.5%. New entrants: China, Korea…and Amazon? And global competition is
growing powerfully too, impacting European construction companies hard. The Engineering News Record’s Top 100 Global Contractors for 2017 found that European firms made up only 23% of the world’s Top 100 Global Contractors in 2017. In 2010, 44% had been European. Compare that to Asia, which rose from 41% in 2010 to 51% in 2017, and the big picture is clear. Most analysts predict that China, India and the US will all be winners in the forecasted 8 trillion USD growth expected in construction by 2030—but not Europe. Companies like China Communications Construction, Hyundai Engineering & Construction and Samsung C&T represent a serious threat to large European incumbents. Taken by revenue alone, even by 2017 the Top Four and seven out of the world’s Top Ten largest construction companies were all Chinese. With many able to offer highly competitive and flexible financing packages. As
we’ve seen, the rise in modular is bringing in new entrants from the manufacturing, supply chain and software engineering sectors. And given all this, who knows, could even digital giants like Amazon or Uber one day see construction as a sector ripe for disruption? If so, who’d put money on the industry in its present state surviving the challenge? The bottom line is that many construction companies are highly exposed. In 2018, we saw huge ongoing efforts to drive efficiencies, increase productivity and establish repeatable delivery. In 2019, the pressure will be even more intense. The need for adaptability has never been more urgent. 2019 will be the year when many companies finally start considering systems like ERP not as isolated back-office finance functions—but essential, joined-up systems that provide urgent coherence, speed and efficiency throughout a project or business. 2019 could be the year when construction takes a giant leap forward, embracing digital adoption. Prediction #3: Digital asset life cycle management, integrating both BIM and ERP, will emerge as a future need-to-have The collapse of Carillion, one of the UK’s largest construction giants, sent shockwaves through the construction industry. The company built and maintained major assets such as schools, prisons, hospitals and power stations across the UK—before collapsing 1.7 billion euros in debt, overnight, in January 2018. While analysts have endlessly debated how and Georgia Contractor
why, insiders point to many systemic faults. Certainly, in a company that size, spread over that many projects, it seems fair to say that without a central, integrated business system it would be all too easy for senior management to get a full picture of the truth. For the truth to be hidden. And for projects to be kept separate and siloed, financially and operationally. Central to ERP’s power for construction companies is its ability to connect and integrate all functions in a project—from finance to operations to design— enabling maximum adaptability. I’ve always argued that Building Information Modelling (BIM) will be a driver of digital asset life cycle management and integration. BIM is an integral part of moving from a document-driven to data-driven world. In 2019, I believe we’ll see the first construction companies take their first steps into discussing how to merge and build on the strengths of combining the two systems: BIM and ERP. Many firms have now started to integrate BIM models into their business. But building BIM on its own without an integrated business system, is only a small part of the picture. As a business system, ERP takes all the functions of the business and provides it with one set of data, enabling it to flow through a project’s life cycle all the way from inception to disposal, and enabling any combination of service or asset management in between. For manufacturers, integrating ERP as a whole business system, rather than a single financial tool, is old news. They’ve been sucJanuary | February 2019
cessfully integrating CAD with ERP for years. However, for many companies in the construction industry,
that journey remains to be made. But 2019 will see many taking their first, vital steps. v

GCAA Annual Workshop & Exposition
By Jeff Wansley | Executive Director | GCAA
A Special Thanks to Our Sponsors Since SB 170 passed in 2015, Transportation funding has become more sustainable and reliable. This has been good for the aggregate business. If we look at the transportation funding history over the last three years, FY 2017 was $1.928 bill, 2018 $1.990 bill, and the 2019 budget will be $1.997 bill, it confirms the steady and reliable funding program (GDOT amended budget request), and, as such, it provides for a fairly reliable demand for aggregate in the years to come. The variable will be the weather and maybe more importantly the shortage of skilled labor. Our hope is that a bipartisan bill will likely be introduced in early in 2019 by Rep. Peter DeFazio (DOr), who is expected to chair the Transportation Infrastructure Committee. We expect that the plan will introduce a major infrastructure bill providing $500 billion for highways, transit, bridges, airports, and water projects. GCAA will work closely with the National Stone Sand and Gravel Association to support this goal. The GCAA looks forward to working with the Kemp administration in Georgia. We will work closely with our partners at the Georgia Highway Association, The Georgia Ready Mix Association, The Georgia Transportation Al26

liance and the Georgia Mining Association. The GCAA will remain focused on the general business, and how to improve business practices and opportunities, keeping good business practices in mind, but managing Performance with Minimizing Downtime. We will continue to work closely with the Georgia Environmental Protection Division as well as on the federal level with the Mining Safety Health Administration. Over the last few years, we have seen more consolidations in our industry, with the latest being the acquisition by Luck Stone of Stephens Industries. We do not anticipate additional changes any time soon. Our annual Management Workshop and Expo in March is entitled “Juggling Demands.� It is a good theme and reflects the positive economic climate we enjoy. v
