Carbon and climate change – its impact on construction
At the recent Construction Climate Challenge conference hosted by Volvo Construction Equipment in London, England, industry leaders said that only big targets will trigger the innovation needed to make a meaningful difference in cutting carbon in infrastructure and construction projects. One area where innovation is rapidly taking place is in the design of construction equipment. I am impressed with the work going on and the cover story this issue is one example: the future use of autonomous machines in roadbuilding. Even today, fuel savings and efficiencies are being driven by developments such as Cat’s “digital heart” in their new excavator line, featured last issue, and Hamm’s hybrid-drive compaction roller this issue. The London conference looked at the new PAS2080 (Publicly Available Specification 2080) standard – the world’s first framework for reducing whole life carbon in infrastructure. This U.K. standard provides guidance and consistency on how to employ material, energy and labour efficiencies to reduce both capital and operational carbon and costs. It could become a model for other countries around the world, driven by the cost savings. “Standards like these are so important right now as they set a definition and trajectory for us to work towards,” says Terri Wills, CEO of World Green Building Council. She goes on to add a fact that surprised me by its magnitude: “Forty percent of our global greenhouse gases are from the construction and building sectors so our focus needs to be on decarbonizing our sites.” Already, PAS2080 is impacting high profile infrastructure projects, such as the building of HS2, the new high-speed rail network linking Britain’s major cities and currently Europe’s largest infrastructure project. Experts behind the HS2 say they have an obligation to reduce their carbon impact and are insisting that all their Tier 1 contractors are PAS2080 accredited within 12 months of contract award. Mark Fenton, climate change specialist for the project, says that bigger projects like this “have to lead and influence the rest of the industry.” Mark Enzer, group practice manager – water and the environment at consulting firm Mott MacDonald, which helped develop PAS2080, and lead author of the Infrastructure Carbon Review, says it is increasingly clear that cutting carbon cuts costs. “Crudely, carbon is a proxy for material and energy use: in an increasingly resource-constrained and competitive world, innovative, low-carbon companies will have an advantage in global markets as well as at home,” says Enzer. “By acting now to reduce carbon emissions, we can influence the Earth’s climate beyond 2035. And that needs to be a key priority for everybody involved in designing and delivering and operating infrastructure: our commercial survival depends on it. As always, it will be businesses that are most capable at change that gain the most.” To be competitive in Canada and the global marketplace, we will need to keep pace with world developments like these and I look forward to covering the resulting innovations.

• POWER BOOST WITH NO TIME LIMIT • DEDICATED HEAVY LIFT FUNCTION • HEAVY DUTY CONSTRUCTION
DON’T SET LIMITS ON WHAT YOU CAN DO. Most excavators come with a power boost function that can deliver extra force when you need it most – but only for a few seconds at a time. What good does that do when you have a whole day’s work ahead of you? The power boost in KOBELCO excavators provides ~10% more bucket breakout force when you need it, for as long as you need it. They also offer a dedicated heavy lift function that provides ~10% more power when lifting and swinging. Combine that with our heavy-duty construction and you can be sure they’ll never back down from a challenge.

Commander II combines simplicity and exclusive control system The Commander II, GOMACO’s two-track curb and gutter machine, is back and now features the simplicity of a two-track paver along with the company’s exclusive, operator-friendly G+ digital control system. The G+ system allows independent track drive and two-speed travel, making the Commander II “easier [to use], faster and better than ever before,” says Kevin Klein, GOMACO’s Vice President of Engineering/Research and Development. It can be shipped on a truck at 8.4 feet (2.6 m) wide. It is equipped with a 60-inch (1,524-mm) wide sectional direct-drive trimmerhead for exacting grade preparation, and can simultaneously trim and pour for maximum concrete utilization. In addition, it can easily be converted for different applications, such as curb and gutter, safety barrier, irrigation canal, recreational path, shoulders and more. The operator’s platform is now isolated to eliminate vibration, and a new pivoting operator’s control console allows the operator to have hands-on control and high visibility no matter what application is being slipformed.
Compact Wheel Loader Lifts More and Moves Faster The 344L is a nimble machine that offers a faster travel speed with smooth auto-shift technology up to 25 mph, making it ideal for those with who have larger jobsites to traverse and for snow removal. Articulation Plus, an industry-exclusive steering system on the 344L, allows operators to lift more during turns than leading competitive machines, the company says. The use of an articulated frame plus rear-wheel steer provides a tighter turning radius, improved stability and additional lift capacity. With a full-turn tip load of 12,650 pounds, operators are able to lift heavier loads and can keep more material in the bucket without making adjustments. In addition, the newly designed loader arms and coupler provide better parallel lifting of attachments and increased visibility, especially when using forks. Pivot and rear oscillation contribute to a smoother ride. Proprietary shift logic reduces operating costs by better retaining material with smooth shifts and decreases operator fatigue. Rim pull control extends tire life by allowing customers to adjust the torque of the machine to the conditions on their jobsites.

N Series Backhoe Loader Line Case has made several things standard that were previously optional and also offers an increased suite of factory options on all N Series backhoe loaders. The all-new pilot-control hydraulic system provides more control in critical applications and improvements have been made to the hydraulic system to reduce cab noise. The fuel economy package is now standard and includes ECO mode switches for both the loader and backhoe functions which allows for greater fuel savings and optimal power and performance. Auto Engine Idle brings engine rpm down to idle when the backhoe controls are not used for a set period of time, and Auto Engine Shutdown will shut down the engine if the machine idles for a set period of time. Both features are adjustable. Engine Protection Shutdown turns the engine off if engine temperature, drivetrain fluid temperature or engine oil pressure go out of normal operating range. The drivetrain has been updated for improved roading and gradeability, as well as more pushing power under load and greater acceleration around the jobsite. 10

Topcon’s new 3D machine control system – the X-53x – offers a faster, modular, easily upgradeable aftermarket solution for excavation. “It features fully integrated GR-i3 receivers for precise positioning of the boom, stick and bucket at all times, as well as the MC-X1 controller, which offers compatibility with all brands and models of excavators and provides a customizable machine control platform to address future project demands,” said Murray Lodge, senior vice president and general manager for the Topcon Construction Business Unit. It maximizes excavator output by up to 30 percent compared to machines without a 3D system and is engineered to be easily upgradeable for future excavation demands as technology becomes available.
Drum Cutter with dust suppression A new excavator attachment – the ER 1500 Drum Cutter – is ideal for tunnelling, special foundation work, demolition and soil mixing, and features a dust suppression system to help meet silica dust regulations. In contrast to water spray cannons, the ER 1500 positions water jets as close as possible to the working area, ensuring that the spray reaches the dustproducing area while making it easy for the excavator operator to control it. The powerful transverse drum cutter has a service weight of 3,858 pounds (1,750 kilograms) and is suitable for carriers of 44,000 to 88,000 pounds (20 to 40 tons). It uses large spur gears driven by high-torque hydraulic motors, allowing the drum cutter to be used in the most difficult conditions. It can also be rotated 360 degrees without having to be disconnected from the excavator, and with low vibration and quiet operation, the ER 1500 can work in sensitive areas. Atlas Copco is splitting into two companies in 2018: Atlas Copco, focusing on industrial customers, and Epiroc, focusing on mining, infrastructure and natural resources customers.

It features an extended wheelbase that delivers a machine weight of just 34,600 pounds (15,694 kg), and comes as standard with a 74-hp, high-torque, Tier 4 Final engine. For working at altitude or in extreme environments, a 120-hp engine is available. The Xtreme XR630 has been designed with six degrees of frame sway, a major advantage for contractors in this compact telehandler category, and weighs just 13,700 pounds (6,214 kg), making it easy to transport between jobs. It comes with a 74hp, Tier 4 Final engine. Lift capacity is up to 6,000 pounds (2,721 kg), maximum lift height is 30 feet 7 inches (9.32 m) and forward reach is 18 feet 5 inches (5.61 m). Xtreme has also made two of its most popular telehandlers even better. The XR1045 has become the XR1147 and now features an additional 1,000 pounds (453 kg) of lift capacity, totalling 11,000 pounds (4,989 kg). Additionally, the XR1147 has a maximum lift height of 47 feet (14.3 m), an increase of 2 feet (0.6 m) over the XR1045, and a forward reach of 31 feet 6 inches (9.6 m). The XR1147 uses the same chassis as the new XR1055 for improved commonality across the product line and comes standard with a 74-hp, high-torque, Tier 4 Final engine. A 120-hp engine is available. Xtreme says that their XR1270 is the world’s tallest fixed-boom telehandler with a 70-foot (21.3-m) maximum lift height. It has been enhanced to lift an additional 3,000 pounds (1,360 kg), giving it a new maximum lift capacity of 15,000 pounds (6,803 kg). The carriage class has also been uprated to C-class, instead of B-class, to handle the higher-capacity loads.
50 M5 XXT truck-mounted concrete pump Liebherr’s Concrete Technology division has introduced a new 50 M5 XXT truckmounted concrete pump, integrating new technologies and capabilities, lowering the overall weight and optimizing product dimensions. With a vertical reach of 161 feet (49 m) and a horizontal reach of 146 feet (44 m), this compact unit provides outstanding working range. There are four different pump options for outputs from 138 to 167 cubic metres per hour. An innovative highlight is the newly developed boom pedestal which, despite considerable weight reduction, provides even more stability. The multi-folding fivesection boom is extremely easy to operate, and alternating pipework close to the boom ensures uniform movement over the construction site. Liebherr is the only manufacturer with the patented XXT narrow support, which is extremely stable and warp-resistant. Front and rear support arms pivot,
which provides a highly flexible and an extremely wide working range for the distributor boom on narrow supports. This is a huge benefit on construction sites with limited space.

Heavy-duty axles deliver performance in harsh applications and enable the use of solid tires for greater uptime. An upgraded forward-neutral-reverse joystick is easier to activate and more ergonomic, improving operator comfort. The wide-fin radiator provides more effective cooling with larger fin spacing which reduces clogging.
Hyundai Construction Equipment
All-Around View Monitoring for Wheel Loaders The Hyundai-exclusive AAVM (All-Around View Monitoring) system, available as an option on Hyundai HX series excavators since late 2015, is now available on new factory orders of Hyundai HL900 series wheel loaders. It uses four cameras mounted on the left and right mirrors, the front of the cab and the rear hood (the standard backup camera) to provide a 360-degree-surround virtual operating view of the jobsite. “Safety on the jobsite is a necessity. Now with the new wheel loader AAVM system on our HL900 series, Hyundai provides owners and operators a safer solution than other options on the market,” says Corey Rogers, marketing manager, Hyundai Construction Equipment Americas. Included in the AAVM system is the IMOD (Intelligent Moving Object Detection) system that senses and warns the operator with onscreen flashing arrows and an alarm when objects come within either of two selectable ranges, 6.5 feet (2 m) or 22.9 feet (7 m), of the wheel loader. The image is integrated into the Hyundai seven-inch colour touchscreen cluster-monitor in the cab. The AAVM system uses Hyundai’s proprietary imaging software to display multiple 3D and 2D views of the operator’s working environment, including a unique bird’s-eye view. 12

tracked excavators 1O-4 by Lawrence Buser, Editorial Director
Excavators are the backbone of construction and account for 50 percent of global construction equipment sales and for this in-depth report, Heavy Equipment Guide asked several manufacturers for updates on trends, innovations and buyer preferences for excavators in the 10- to 40-metric-ton range and for advice to buyers.
“One of the top trends we are seeing, specifically in the Canadian and North American market, is the increased demand for reduced-tail-swing machines.” David Young, product market manager, excavators, John Deere Construction & Forestry and Hitachi Construction Machinery
Heavy Equipment Guide
>> february 2018
In the 10- to 40-metric-ton range of excavators, the two most popular sizes are 35 metric tons followed closely by 21 metric tons, according to Andrew Dargatz, brand marketing manager, Case Construction Equipment. “The 35-metric-ton size is dominated by the rental, non-residential construction and infrastructure markets, while the 21-metric-ton size class is sold mostly into the rental market, the nonresidential construction market and then a pretty even mix between infrastructure and residential construction,” he says. “Although 21-metric-ton size class is commonly sold in the infrastructure markets, the 35-metric-ton size class is notably the more sought after size machine.” Aaron Kleingartner, marketing manager, Doosan Infracore North America, adds that the popularity of this mid-size excavator group is higher than larger crawler excavators because, in part, the machines in this size are typically more versatile and can be paired with a variety of attachments.
“One of the top trends we are seeing, specifically in the Canadian and North American market, is the increased demand for reduced-tail-swing machines,” says David Young, product market manager, Excavators, John Deere Construction & Forestry and Hitachi Construction Machinery. “These machines are becoming much more popular and sought after because of their ability to work in confined areas without moving from the deviated track footprint. We are seeing reduced-tail-swing machines expand their offerings into other size classes within the 10to 40-metric-ton range because of these reasons.” Dargatz says that Case has noticed this switch to minimum-swing radius is most evident in the 14-metric-ton size class, where they have seen exponential jumps in just the last few months. He explains that this is happening for a couple of reasons. One is that minimum swing radius allows contractors to get in closer to various impediments or work along roadsides without having to close as many lanes of traffic. The other is that manufacturing design has improved
Technology is a major trend in North America for tracked excavators as it “allows contractors to realize significant efficiency gains, and it improves productivity for even the most inexperienced operators.” Brian Stellbrink, product application specialist, hydraulic excavators, Caterpillar
Sebastian Witkowski, product marketing manager, Komatsu America Corp., says that they have seen more OEMs introducing factory integrated GNSS. In fact, for several years now the company has been promoting the fact that this system can reduce construction time by up to 63 percent versus conventional stake and survey construction methods. Customers are also looking for machines with better fuel economy and less impact on the environment, according to David Donneral, specialized machinery sales manager, Kobelco USA, but they don’t want to lose performance and production or have to pay an unrealistic premium. He says that a solution for some applications is hybrid power, such as their new 20-ton hybrid machine. Matthew McLean, product manager, Volvo Construction Equipment, expects that demand for excavators in Canada will continue to grow. “The Canadian market will be impacted by the federal government’s plan to invest $180 billion in infrastructure over 12 years. With a focus on public transit, green initiatives, community-building, trade and transportation, and rural and northern communities, there is sure to be a higher demand for excavators in the coming years.”
Innovations and benefits
Mid-size excavators, such as the Doosan DX225LC-5 (above), are versatile and can be paired with a variety of attachments.
to the point where minimum-swing-radius machines provide lifting and cycle times that are comparable to their conventional counterparts. Technology is a major trend in North America for tracked excavators as it “allows contractors to realize significant efficiency gains, and it improves productivity for even the most inexperienced operators,” says Brian Stellbrink, product application specialist, hydraulic excavators, Caterpillar. “Standard technology such as Cat Grade with 2D system, Grade Assist and Payload on our new Next Generation 320 and 323 excavators can increase operating efficiency by up to 45 percent.” “Telematics and the overall industry use of technology is another emerging trend” that John Deere has observed, says Young. “The expanded use and customer demand for technology and telematics is becoming broader and more prevalent because of all of the information it provides fleet managers. At first, telematics was thought of as an additional feature, but now it’s an industry norm and becoming an industry must.”
“One of the biggest innovations is machine guidance and machine control in a wider range of machine classes,” adds McLean. “Two years ago, machine guidance and control systems were only available from a couple of brands on 20-ton machines. At CONEXPO 2017, most major brands had announcements talking about rolling their systems out on new models.” An example, he says, is Volvo Dig Assist as it allows an operator to easily input job specifications, see the real-time position of the bucket and machine in relation to target grade and depth, and track progress to ensure the job is done right the first time, all the time. With the optional In-Field Design functionality, the operator can draw custom digging profiles directly from the cab. All of these features help operators save time, increase jobsite efficiency and reduce the need for rework. “Dig Assist has had a big impact in Canada and there is a lot of interest. In fact, half of the orders Volvo has received for Dig Assist have come from Canada,” says McLean. Volvo plans to add this system to more class sizes of tracked excavators, as well as to wheeled excavators, this year. Caterpillar recently made the most significant change in 25 years to their excavator line. They have just introduced a new platform that is built around what Caterpillar is calling “a digital heart” that allows these machines to work efficiently at digital jobsites, says Stellbrink. “Sensor technology mounted to the boom, stick and bucket of our new Cat 320 and 323 excavators work in concert with standard machine technologies to allow the operator to achieve grade quickly, prevent rework and be confident the truck is properly loaded,” he adds. The sensors also allow an electronic fence to be put around a barrier so that the stick doesn’t reach beyond a set point, he adds. This
improves safety by preventing the stick from hitting obstacles such as buildings or overhead obstructions. Kobelco has been working closely with Trimble for several years to develop advanced control systems that are factory installed on their excavators. “The system does not use specialized (and potentially expensive) electronic sensor cylinders or mechanically controlled position sensors,” says Donneral, “but rather newly developed, state-of-the-art, gyroscopic sensors similar to those used in modern airliners and stability systems on automobiles.” He adds that most manufacturers offer a factory installed telematics system that allows the customer, dealer and manufacturer to receive operating information from the machine in real time, allowing for better decisions to be made, whether it is machine utilization, service issues or recordkeeping. “Since these systems are proprietary to each manufacturer, companies like Trimble are working to bring a universal platform to the market to allow customers one system and one dashboard to monitor their multibranded fleet. Although this won’t allow all of the detailed information that the OEM system may get, it is more than enough to assist them in making business and service decisions.” Komatsu has been busy launching machines with integrated 3D, and training distributor-level experts to help customers maximize its use, reports Witkowski. For those with second-generation machines, refinements continue, such as joystick controls, as well as base machine improvements, including the surround-camera-system, KOMVISION, which offers a birds-eye view around the machine. Case has recently overhauled its entire line of hydraulic excavators, replacing the C Series with the D Series. The core areas they focused on in the redesign were speed and precision – specifically the ability for the controls to be super responsive and stop the boom and bucket exactly where the operator wants them to stop each time, allowing operators to improve cycle times. “Each D Series excavator features a new, electronically controlled pump, a larger control valve and multiple sensors,” says Dargatz. “This combines with the Case Intelligent Hydraulic System (CHIS) to make the best use of the excavator’s hydraulic power and momentum – ultimately increasing speed and performance while simultaneously improving fuel efficiency.” John Deere has been using customer feedback to continue innovating the design of their hydraulic systems, notes Young. “The three-pump system is our focus right now, because of all of the benefits it brings to our customers. It allows operators to have full flow and pressure to the swing function at all times, no matter the terrain or the force of gravity they may be working against. The three-pump hydraulic systems enable operators to not lose torque, speed or efficiency even on the toughest jobs.” One of the newest innovations in Doosan excavators is Smart Power Control (SPC) in the Tier 4–compliant dash-5 models, which helps reduce fuel consumption by as much as seven percent, says Continued on page 18 february 2018

tracked excavators: 10–40 mt
Volvo EC220E The 22-ton EC220E is Volvo’s premier mid-sized crawler excavator fitted with a Tier 4 Final Volvo D6 engine. The fully optimized hydraulics system and integrated work modes deliver the precise amount of power required to complete the task at hand, while the auto engine shutdown feature helps further reduce fuel consumption and emissions by switching off after the excavator has been inactive for a pre-set amount of time. Versus the D-Series model, the EC220E delivers a five percent improvement to fuel efficiency. Newly available as an option on the EC220E is Volvo Dig Assist – the Volvo machine control solution that provides real-time guidance for operators to ensure job parameters are met more quickly, more accurately and with improved site safety. Viewable on the 10-inch touchscreen Co-Pilot interface, Dig Assist allows the operator to monitor grade and depth in real time, as well as providing In-Field Design functionality that allows the operator to draw custom digging profiles directly from the cab or import 3D models directly into the interface.
Liebherr R 918 The newest addition to the Liebherr excavator line is the R 918, with an operating weight between 19 and 22 tonnes, perfect for earthmoving, trenching and pipe laying. A large selection of attachments also makes the machine extremely flexible for more specific work. A new Tier 4 Final engine has a power rating of 163 hp (120 kW). It uses a urea injection SCR system and an oxidation catalyst. A particulate filter is available as an option. There is an optional automatic idle-stop when the engine is inactive. The cab is equipped with a pneumatic seat with vertical and longitudinal absorption as standard and a fully retractable windscreen. A high-resolution seven-inch colour touchscreen is easy to use.

Buyer preferences
Continued from page 15 Kleingartner. Doosan also provides sideview cameras, which are especially important on jobsites where there are many machines moving and when working in tight spaces, and the DoosanCONNECT telematics system, which dealers and customers use to remotely monitor excavators, track their performance and help minimize machine downtime. Sometimes the advances seem simple but provide significant gains. For example, Cat’s new excavator platform uses multiple electric fans which independently monitor hydraulic oil, radiator and air-to-air aftercooler temperatures to deliver the exact airflow required and lower fuel consumption. Also, the electro-hydraulic system and large hydraulic pump allow the machines to maintain performance at a lower engine rpm, adding to fuel savings. In addition, Stellbrink comments that Caterpillar’s next generation excavators have extended and more synchronized maintenance intervals which enable more work to be completed at up to 15 percent lower maintenance costs compared to the previous 20-ton series. Notably, the hydraulic return filter has a 50 percent longer service life of 3,000 hours, and the new air filter design provides double the capacity for extended service life. Safety continues to be in the minds of manufacturers and Kobelco has anti-collision devices currently in the works and soon to be released, says Donneral. These devices will notify the operator, sound an alarm and prevent the machine from swinging or tracking when there is an object or person in close proximity that could be hit. All of these items help to ensure the safety of the operator, property and people on the ground. New hybrid machines in popular size classes improve fuel efficiency and machine response, says Witkowski. “With machines using electric swing motor technology – such as the Komatsu 30-ton HB365 – users can expect up to 20 percent improvement in fuel usage, while maintaining productivity of a standard 30-ton excavator.” While several manufacturers have hybrid machines in other countries the excavators lack performance and so they have not been as popular here in North America, says Donneral. “Kobelco has developed a new 20-ton hybrid machine for the North American market that has the same, or better, performance as a standard 20-ton excavator, while using lithium ion batteries (instead of capacitors) and an electric swing motor to reduce fuel consumption and emissions. There is a minor price difference, but the added performance and fuel savings helps offset this cost.” 18

“Buyers are looking to purchase excavators with the right balance of technology and features matched to the work completed,” says Stellbrink. “It’s no longer all-in or all-out with regard to technology. Customers demand options to get the most work done at the lowest cost.” He adds that this is why Caterpillar offers three different 20-ton models – the 320 GC, 320 and 323 – in their newest generation of excavators, so that customers have more model options, more standard scalable technologies and more price points. Contractors want a simple buying process, according to Dargatz, which is why Case has made more features standard on their latest generation of excavators than previous models. He says that their goal is to “simplify the buying process and give contractors more of what they need.” Dargatz adds that while contractors want to purchase larger machines that can increase production, they also want to stay within their trucking and permitting limits. “This is also why we see such demand for these machines in the rental markets.” Witkowski says that buyers are looking for high productivity machines, more breakout force, faster cycle times and value. To make the most of new technology, Witkowski adds, Komatsu provides support and training, plus a dedicated business solutions team who serve as freeof-charge consultants for jobsite optimization, fleet recommendations and telematics data analysis. This free service applies for the life of the machine. Witkowski adds that technology that raises efficiency is winning in the marketplace. This includes integrated machine control and telematics that help customers make better business decisions. With the increase in infrastructure spending, McLean at Volvo says that short-swing excavators have been growing in popularity as they can work in one lane without hindering traffic or causing a road to be completely shut down. There are three main things that customers look for, says Young at Hitachi. First, customers want to know that you have a machine that is efficient to be competitive in the industry. The second is reliability to maintain uptime. And the third is durability. To sum up, he says: “Customers want to know machines can tackle their toughest jobs, letting them get more done, day in and day out.” Versatility is an attribute that Doosan has noticed buyers want. “Machines in this size class – particularly in the 10- to 25-metric-ton size – are sometimes thought of as being more versatile and used in general construction activities, such as site prep and digging basements or footings,” says Kleingartner. “They
can be used for everyday digging or lifting tasks, and may be equipped with a quick coupler to quickly and easily change attachments – from a bucket to a hydraulic breaker.” An example he gives is the Doosan DX225LC-5 crawler excavator, their most popular model in this size class, as it offers powerful digging and lifting, plus auxiliary hydraulics to provide power to attachments. Reduced-tail-swing excavators, like the DX140LCR-5 and DX235LCR-5, also offer versatility when working next to a barrier or near a bridge underpass, he adds. “Customers are buying special application machines to do one specific job as efficiently and profitably as possible,” according to Donneral at Kobelco. He explains that this is a reason the company is introducing their specialty High Reach and Demolition SK350D and SK400D machines. These models assist in safely and efficiently removing buildings and structures from urban areas and make room for new construction. Another example is the Kobelco ED160, which combines a 14-ton excavator with an HD six-way dozer blade to save the operator from having to bring two machines to a jobsite. The customer can do multiple jobs with one machine and one operator, thus saving time and the costs of trucking while also increasing the utilization of that machine. Young notes that operator comfort is a key preference for Deere’s customers and explains that “the hydraulics aspect of John Deere equipment provides customers with optimal comfort by minimizing fatigue during long operator shifts. This allows operContinued on page 22

Advice for prospective buyers
When it comes to buying a new excavator, there are a number of considerations. We asked the experts to provide suggestions that are important and may be overlooked. Case • Features like LED lights and additional cameras improve visibility and help reduce operator strain and fatigue. • Rubber track pads minimize damage on paved surfaces. • Get a powerful enough machine to accomplish the work you do now, and the work you may want to do three years from now so that you can grow your business. • Leverage attachments to expand your services offering. Caterpillar • Don’t purchase an excavator on price point alone: match performance to the job type; consider hour usage, material density and the type of jobs; and determine if technology will help to increase performance. Selecting a base machine solely on price costs contractors more money in higher operating costs and lower productivity, which impacts the bottom line. Consult with your dealer to discuss specifically what you need from your next excavator, and the representative will match the right model with the right features and technology to maximize production and profit potential. John Deere & Hitachi • Prospective buyers should consider the mobility factor of the machine. If it will be relatively stationary, buyers should consider going up a size class to reap the additional benefits from larger machines. On the other hand, if the machine will need to travel to multiple locations, buyers should consider their regional equipment transportation laws and potentially consider going down a size class based off of the regulations in their area. Doosan • Do you need a quick coupler to make the machine more versatile? Does the machine come equipped with auxiliary hydraulics to operate a clamp or a tilt bucket? • How often will the machine be moved? Could a smaller excavator do the same job as a slightly larger model? You should be aware of local weight restrictions and transportation requirements. Can you use an existing truck and trailer? Will you need to hire a company to move the machine from jobsite to jobsite? • What type of maintenance plan do you want? With telematics programs becoming more prevalent in the construction industry, should you consider transitioning a preventive maintenance plan to a local equipment dealer? Kobelco • Purchase your machine with additional hydraulics capacity built in from the start. New working tools are coming out that require some type of additional hydraulics. By using the proper working tools and attachments, owners can great22

ly increase production and reduce damage that is done when completing a job with the wrong tool. • Telematics is becoming an industry standard that is there to assist your business if you understand it. Don’t be afraid to ask about the technology and learn about it. • Attend trade shows and research new ways to complete specific jobsite

tasks and learn about machinery that can help. Volvo • There is a large number of machines to choose from in this size class, so it might be key to know the type of work you will be doing so that you don’t buy a larger machine than you actually need for the job. If you know exactly how much power you will
need for the jobs you plan to do, you can avoid wasting money on a larger machine than is necessary. Komatsu • To maximize machine investment and improve resale value, customers should take advantage of every support service available. Whether fee-based or free-of-charge services, utilize them! HEG

compaction (R)evolution Hamm has made two significant advancements in compaction rollers: the evolution of a power system that uses a hybrid mix of diesel and hydraulic power and a revolutionary autonomous compaction roller which Hamm says will make road construction of the future better, more cost-effective and more efficient. Innovative hybrid-drive compaction roller
The new hybrid-power compaction roller is quieter, has lower fuel consumption and requires less maintenance than a conventional roller.
Hamm has developed a unique hybridpowertrain system for tandem asphalt compactors. The totally new system combines the traditional internal combustion engine, which covers the base load, with a hydraulic accumulator that meets peak loads. Hamm will introduce the hybrid powertrain system to North America in the HD+ 90i PH model at World of Asphalt 2018. Hybrid solutions combine two power technologies. In the automotive sector, combinations of internal combustion engine and electric drive are common. Hybrid power attempts with electric motors in rollers proved unconvincing so Hamm tackled this problem with a novel approach, combining an internal combustion engine with a hydraulic system. Hamm says they are the first roller manufacturer to develop a technical solution suitable for series production.
HD+ 90i roller with hybrid powertrain
For the first hybrid power models, Hamm chose the HD+ 90i, a popular
tandem roller in the medium weight class. Up to now, this roller has operated with a 114-hp (85-kW) diesel engine complying with EPA Tier 4 Final exhaust emission standards. A detailed examination of the actual engine load during compaction showed the Hamm developers that the peak loads were only needed occasionally, and even then for just a few seconds. This is the case when the roller starts up for example or the vibration/oscillation is activated. In the new hybrid power roller, these brief peak loads are handled by a hydraulic system, enabling the roller to be equipped with a smaller diesel engine for the same performance. The load on the diesel engine is also reduced by the use of efficient radiator fans that are electrically operated.
Hydraulic power storage on board
As soon as the power demand falls below the maximum load of the internal combustion engine, a pump fills the hydraulic accumulator. If a great deal of power is called for, such as when starting the vibration drive, the hydraulic system functions as an auxiliary drive, able to supply a maximum short-term load of up to 27 hp (20 kW). Following this, the cycle begins afresh with the refilling of the accumulator. Hamm says that this principle functions splendidly because, for normal applications, the maximum load is always only called
Left: Power distribution on the HD+ 90i PH with hybrid powertrain. Maximum load (green) is only called up for brief periods. In all other working situations, there is an adequate reserve of power with which to replenish the hydraulic accumulator (orange) for the next demand. 24

up for a matter of seconds. Afterward there is sufficient time to replenish the accumulator.
Lower fuel consumption, quieter and requiring less maintenance
This results in numerous benefits: for example, the nine-metric-ton HD+ 90i PH roller can be powered by 74-hp (55.4-kW) engine in place of a 114hp (85-kW) unit – and with the same compaction power. The smaller engine does not require an SCR catalytic converter or DEF. This results in advantages in terms of handling and maintenance. What’s more, the powertrain is markedly quieter. Last, but not least, the hybrid power train, in combination with the electric fan drives and a start-stop system, enables significant savings of up to 15 percent in fuel consumption. This also substantially cuts CO2 emissions. The hybrid system underwent field trials in selected markets during 2016 and 2017. Hamm expects the double vibration (VV) and vibration-oscillation (VO), as well as the smooth drumpneumatic “combi” rollers (VT), will be available in 2018 but no specific date has been set.
Autonomous rollers – the future of compaction
Another interesting development in compaction technology is Hamm’s self-driving roller. Trials of the autonomous rollers have been underway on a test track since 2014. Although it will be some years until Hamm rollers are driving and compacting entirely autonomously, the studies and trials at Hamm have already demonstrated that such machines allow compaction quality and efficiency to be noticeably increased. In modern cars and trucks, the use of driver assistance systems is experi-

The autonomous roller has no cab and thus could accommodate a much larger front drum and carry more water. encing rapid growth. GNSS systems for navigation, speed control, spacers, lane assistants, parking and steering aids are increasingly establishing themselves. In many countries, they are even standard on new vehicles. These assistance systems form the basis of the self-driving trucks and cars that are being developed by industry pioneers, and that are already being put through their paces on test tracks. Assistance systems are also rapidly establishing themselves on construction equipment. “Rollers for asphalt and soil compaction will be among the first [construction] vehicles in which such systems will widely establish themselves,” says Stefan Klumpp, mechanical engineer and CTO of Hamm AG. “This is because, in many respects, they are closer to cars than many other types of machine are . . . [which] is why we have been dealing with this subject for some time at Hamm. “We know of no other company in our industry with a self-driving roller,”
says Klumpp. “Our investigations have shown that such rollers [will] enable our customers to increase compaction quality and efficiency. “We have noticed that other leading companies in their sectors, too, are looking into the opportunities and impacts of the autonomous construction site. “Against the background of limited availability of qualified personnel on the one hand, and high-quality, highly efficient and resource-saving use of machinery on the other, the objective is to further optimize construction processes.”
Design study already complete
Axel Römer, head of R&D at Hamm, and his team have already examined what a self-driving roller might look like. “We have considered technical, constructive and economic aspects and evaluated them in various studies,” he says. “The result: a driverless roller will not have an operator’s plat-
form anymore but will need significantly more sensors to monitor not only the compaction parameters but also the area surrounding the roller. We have connected these requirements and see many new and constructive possibilities. For example, we could construct autonomous rollers with significantly larger drum diameters, bigger water tanks and more space for the batteries of electrically powered rollers. This offers advantages in terms of quality, environmental friendliness and efficiency.” In collaboration with industrial designers, Hamm developed a concept and design study. The result is impressive. The drum of the ninemetric-ton machine has a diameter of almost two metres (six-and-a-half feet). At the same time, the overall height of the machine is significantly lower than current machines that have a cab or roof.
Assistance systems already in use
There is already one assistance system in use on Hamm equipment: HCQ Navigator. It uses an on-board computer and GNSS data to provide real-time display of the areas that have already been compacted, including how often and by how much. This is
complemented by driving functions, such as automatic reversing or speed control, as well as safety features, such as rear-view cameras. All of these relieve the burden on operators and help to increase compaction quality. The developers at Hamm are working on other systems, including a lane assistant and additional steering aids, and are further developing the HCQ Navigator.
Complex sensor technology and programming
However, for rollers to be able to maneuver autonomously in carrying out high-quality compaction, significantly more sensors and more intelligent software will be needed than is found in today’s machines. The sensors will capture all relevant data from the area surrounding the roller. This includes spatial position, direction of travel, distance from other objects, current material parameters of the surface to be compacted (e.g. temperature and rigidity) or weather information (e.g. wind or cooling rate). The rollers must compare this data with specifications for the area (which parts should be compacted), the rolling pattern (how many and which rollers are needed to work together), and the desired

compaction (void content). Another factor is compaction strategy, including instructions for cornering before reversing, edge-finishing, vehicle speed, the use of exciter systems and other considerations. In short, this is a complex undertaking.
Driverless shadowing roller
Hamm has already successfully completed the first steps of the journey, not just on paper but in practice, with testing at the Tirschenreuth factory in Germany and the development of a driverless shadowing roller that follows a preceding machine. The tests have been conducted around the clock for weeks at a time. In these trials, the machines autonomously complete a specified program, drive to refuelling points and park when the test is completed. To prevent collisions with people or objects, Hamm has outfitted the rollers with comprehensive systems to monitor the surroundings. “We have now clocked over 10,000 hours on this test track and learned a great deal about autonomous driving in the process,” explains Hans-Peter Patzner, who collaborated in the development of the control system for the project. Patzner is now looking ahead to the next challenge, because the current construction of a second test track at Hamm will enable two different rollers to drive simultaneously. “For this, we have designed a collision monitoring system, which represents another important step towards autonomous driving.”
Gains to be made step by step
Römer says they can leverage a great deal of potential by automating the compaction process. “There will be an increase in quality thanks to compliance with lanes and windows of speed. Targeted braking [prevents the roller from] going beyond the rolling areas and any subsequent over-compaction. Not least, the extremely precise change of compaction lanes helps to prevent deformation. Together, these systems automatically lead to greater efficiency, in particular when such concepts are applied across the fleet.” This development is a gradual,
Progressive stages in the development of autonomous compaction include assistance systems, monitoring of surroundings and other concepts which will be developed in the future. step-by-step process. Initially, while monitoring of surroundings is not sufficiently precise for fully autonomous driving, an operator will have to be in the cab. Hamm says that they would only take over in specific situations, such as refuelling, during loading and unloading, or in the event of unforeseen incidents. A similar situation already exists in aviation. In modern commercial aircraft, the autopilot and other systems carry out the greater part of in-flight tasks. The pilots only control the aircraft during takeoff and landing, and in exceptional situations, otherwise their main task is to monitor the processes.
Legal and other considerations need to be overcome
Aside from the technology, there are a number of legal issues to consider before such rollers can be put to work on the autonomous construction site of the future.
A self-driving roller requires numerous sensors, such as radar systems, laser sensors, cameras, GNSS receivers, infrared sensors and incline sensors.

Just as with the development of autonomous cars and trucks, there are a number of questions to consider. Who is liable in the case of damage caused by a self-driving machine: the manufacturer, the owner or the planner? Should the control system be configured so that nearby objects are protected, or should optimum compaction quality always take precedence? Manufacturers and users will have to discuss such aspects with clients, authorities, politicians and legislators. “To take a step closer to selfdriving machines, the general environment must change, including the construction processes,” says Klumpp. “In our industry, self-driving machines are found in the mining sector, for example. There, highly standardized work is carried out in closed systems; there are few points of contact with the outside world and few unforeseeable influences on the process. Under such clearly defined boundary conditions, giant dumpers are already transporting rock across large mines that span kilometres – without a driver. “In road construction, by comparison, the processes are far less clearcut and less easy to structure. Every construction site is a little different. There is also much more contact with the surroundings (and thus more potential hazard), and user behaviour is not uniform. “So that we can continue to leverage potential through automation, we would have to introduce, for example, larger construction sections and more standardization in road construction. In turn, this requires a change in thinking among planners and construction companies.”
From roller operator to roller manager
Ultimately, the job description of the roller operator will also change. First of all, further automation could alleviate the issue of skills shortage. The job description would change again in the subsequent step, when shadowing rollers or largely remotecontrolled rollers become established on the construction site: from an operator steering a machine to a roller manager who configures and supervises an entire fleet of machines – perhaps even working from an office. Hamm sees this kind of development initially occurring in the highwage countries, provided that it entails qualitative and commercial advantages. In this case, it would be the achievement of cost savings through greater efficiency and with fewer staff. In addition, re-work would be eliminated thanks to higher quality. Of course, this will demand suitable interfaces and planning tools on the part of planners and customers, as well as a corresponding legal framework. This environment will have to evolve in parallel with the machines. “We have formulated our vision. This has resulted in individual projects that, little by little, will lead us to autonomous compaction,” says Klumpp. “For some, our long-term objective may still sound like science fiction. But in 20 or 30 years, many aspects will already be reality – even routine. Eventually, aided by our developments, the road construction of the future will become even more cost-effective, more efficient and better.” (Note: Deere Company acquired the Wirtgen Group, which includes the Hamm brand, in late 2017.)

World of Asphalt & AGG1
orld of Asphalt will be held in Houston, Texas, from March 6 to 8 and features educational programming and exhibits focusing on the latest technology and innovations for the asphalt industry. The Agg1 Aggregates Academy & Expo, co-located with World of Asphalt, offers educational sessions and exhibits on the latest developments for the aggregates industry. The following are highlights of products that attendees can expect to see at the shows. Ammann recently began distribution of asphalt-mixing plants in North America. Key products include the ABP HRT High Recycling Technology
Plant, the ACM Prime Asphalt-Mixing Plant and RSS 120-M Shredder. The ABP HRT plant is an ideal fit for asphalt manufacturers who need to incorporate large proportions of RAP without sacrificing production capacity and quality. The HRT is a “two-inone” plant featuring both warm and cold recycling systems that can be used simultaneously. There are two warm recycling systems to choose from. One is the conventional concurrent flow dryer for RAP additions of up to 60 percent. The second is Ammann’s latest development in warm recycling, the RAH100, which can utilize 100 percent RAP. The ACM Prime Asphalt-Mixing
Ammann’s RSS 120-M shredder, iron separator and screener prepares RAP for the asphalt plant.

Top: Cat AP355F paver. Above: Asphalt Drum Mixers’ EX120 asphalt plant processes up to 50 percent of RAP. Plant is ideal for completing a number of small jobs in varied locations and where frequent transport is required. It is an ideal initial acquisition for paving contractors looking to introduce asphalt production into their businesses. The ACM 140 Prime offers output of up to 154 U.S. short tons per hour. It is engineered for smaller volumes and therefore produces them efficiently, delivering cost savings in fuel and electrical energy consumption. Recycled asphalt can be utilized with this plant. The entire plant and three cold feeder bins fit on two axles during transport. The RSS 120-M Shredder, Iron Separator and Screener is a mobile machine that prepares RAP for use in an asphalt plant. The shredder’s crushing system maintains desired grain sizes, which is important because it dramatically reduces the fines that make RAP sticky and difficult to work with. The EX120 asphalt plant will be shown by Asphalt Drum Mixers as a solution for producers who need a portable counterflow plant that can process high percentages of RAP – as much as 50 percent. This compact, 120-tph plant features single-drum counterflow technology. Counterflow
technology with separate drying and mixing zones allows the EX120 to achieve maximum heat transfer and fuel efficiency. The system virtually eliminates unsafe carbon emissions that are a common problem with drum mix plants. ADM further reduces emissions by designing the counterflow system to reintroduce gases back to the drum’s combustion zone. Engineers designed the EX Series for smaller output and optimal transport. The entire EX120 plant sits on one chassis for easy movement from site to site. In addition, one plant operator and one loader operator can control the EX120. Bomag will display its most powerful cold milling machine, the BM 2200/75. With its 760.3-hp (567-kW) diesel engine, the BM 2200/75 delivers high-performance milling of half-lane widths reaching 86.6 inches (2,200 mm) at depths of up to 13.8 inches (350 mm). A range of quick-change milling drum options – from fine to standard to power for tough applications – are available to meet specific jobsite requirements. A 35.4-inch-wide (900-mm) conveyer system quickly channels material from the cutting chamber and hydraulically folds for efficient transportation.
The upper conveyor swivels 60 degrees left or right of centre, allowing the mill to efficiently discharge material to either side of the machine. Bomag’s unique BMS 15 milling tooth holder design delivers superior productivity; the company says that this extends service life by up to 30 percent over other systems. Its quick-change tooth design requires approximately 25 percent of the time required to change the teeth of conventional systems. The new Caterpillar PM822 Cold Planer is a highly productive, highly maneuverable half-lane milling machine capable of controlled full-depth removal of asphalt and concrete pavements in a single pass. Operating weights for the new models range from 36,130 to 37,500 kg (79,630 to 82,650 pounds), and cutting widths from 2,010 to 2,505 mm (79 to 98.6 inches). The new machine uses the Cat C18 ACERT engine rated at 563 kW (755 hp), meeting EPA Tier 4 Final emission standards, and is iso-mounted to reduce vibration. Also on display will be the AP355F Asphalt Paver, which is designed for efficient production in mid-sized applications, including parking lots, urban streets, cycling and walking paths, trenches, and narrow shoulders. The AP300F and AP355F are equipped with new electrically heated SE34 Series screeds, available in vibration-only and vibration/tamper-bar configurations. These pavers also feature engine Eco-Mode, auto-fill feeder system, single-touch feeder system activation and automated travel mode. From material extraction to processing, ESCO offers a range of blades, crusher wear parts, lip systems, ground engaging tools, attachments and wear management. At World of Asphalt, ESCO will showcase the latest in tooth systems, crusher wear parts, blade systems and other high-performance products. The Gencor Portable Ultraplant for hotmix asphalt features a totally integrated drum concept that allows highproduction continuous mix with high volume and high moisture recycle. As a result, Gencor says that their plants are accepted in the most stringently regulated and environmentally sensitive regions. Designed for minimal structural vibration, Haver & Boecker’s Tyler FClass vibrating screen is ideal for tough applications, such as scalping and classifying ores, minerals, stones, sand and gravel. The F-Class offers three screen decks and features a double-eccentric shaft design that’s supported by four high-performance double-spherical roller bearings. The vibrating screen is ideal for screening situations that require consistent load-independent performance at constant g-force in all operational modes. To minimize downtime for screen media change-outs, Haver & Boecker equips cambered decks on the F-Class with its Ty-Rail quick-tensioning system, which cuts media replacement time by about 50 percent. An optional chassis offers portability as well as simple setup in less than 30 minutes. Each

crane solves handling of materials for demolition and Rebuild at iconic library The Terex luffing jib tower crane gave work crews more flexibility with material removal which had to be done via the rooftop of the Vancouver Public Library.
Heavy Equipment Guide
ew construction projects always come with a set of challenges, but the site and lifting needs are usually straightforward enough that several different crane options fit the requirements. Building reconstruction, on the other hand, typically comes with its own unique challenges. Often there are obstacles in the way that make selecting the right crane much more difficult, and bidding the right crane can be the difference between getting the job or moving on to the next opportunity. Major metropolitan downtown reconstruction projects offer even more challenges for the lifting contractor. It is a virtual certainty that the site will be surrounded by structures on all sides, making it a tight fit for mobile cranes. Busy streets make it nearly impossible and sometimes cost-prohibitive to block off a road for a significant period of time. This is precisely the type of demanding project facing contractor Smith Bros. & Wilson (BC) Ltd. (SBW) of Vancouver during the demolition and re-
>> february 2018
construction of the 8th and 9th floors at the downtown Vancouver Public Library (VPL). The tasks included converting what were once Provincial government office spaces into additional library space, meeting rooms and an urban green space – while keeping the library open to thousands of visitors daily. Demolition and construction activities required many materials, large and small, to be moved. “All the demo material had to be removed,” explains Tyler Brown, general superintendent for SBW, “and the library only had service elevators to get material from the top floors to street level. During the tender phase, we saw the need to hoist many items, including large-span escalators to get people up to the green space. It was quite a challenging prospect.”
High profile and tight spaces
VPL is a very high profile project for the city, as the building’s distinct design makes the library a focal point in the downtown area. While the historical look allows it to stand out, it also poses unique challenges that require much preplanning in
order to properly bid. “The library is designed after the Roman Colosseum and surrounded by an elliptical wall on the east side,” comments Dean Arsene, crane rental and sales representative for Leavitt Machinery of Vancouver, an authorized Terex Cranes distributor. “We started discussing the project with SBW in late 2016, and all options were reviewed.” Like most contractors submitting bids, SBW initially considered mobile cranes to tackle the heavy lifting from street level. Unlike those companies, however, SBW saw several drawbacks that made planners rethink the option. “The structure’s shape required a minimum of a 500-tonne (600-ton) capacity class mobile crane to hoist large materials to and from the upper floors because it would be boom bound,” says Brown. Given the possible setup locations for a mobile crane at the site, smaller cranes just did not offer the capacity to lift many objects at the required boom lengths and working radii. “This meant we would have had to shut down an entire street, and mobilization costs

would have been high. By the time we counted everything that needed to be hoisted, it was cost-prohibitive to use a mobile crane.” The next option for SBW was tower cranes. They looked at flat top, hammerhead and luffing jib designs. “The job required a 180.4-foot (55m) boom radius, and the flat top and hammerhead cranes didn’t offer the capacity we needed for the escalators without breaking them down,” mentions Brown. Plus, there was a more pressing issue, as the crane would be placed about 50 feet (15.2 m) from an adjacent structure. “Those booms were too long, and they didn’t have the freedom to slew without hitting a structure, so these designs were not an option,” explains Arsene. For SBW, the only option to costefficiently support demolition and con-
struction efforts on the VPL project was a luffing jib tower crane, and the Terex CTL 430-24 offered the reach and capacity for the job. “Through our discussions with Leavitt, we calculated the luffing jib as the most economical hoisting logistics solution for us,” says Brown. Steve Filipov, president of Terex Cranes, says the company offers a complete line of tower cranes as part of its lifting solutions because of challenging projects like this. “The VPL application is one of those unique cases where the mobile cranes we manufacture aren’t the most economical solution for our customers,” he says.
CTL 430-24 rising
Bidding the job using the CTL 430-24 crane helped SBW receive the contract. For the year-long renovation project, SBW entered into a six-month
rental agreement with Leavitt for the 26.5-ton (24-tonne) class Terex luffing jib tower crane. Its tower required seven HD23 22.6 segments to reach the needed jib base height of 147.6 feet (45.0 m). To cover the entire site, the CTL 430-24 was equipped with a 180.4-foot (55-m) jib. A 15-degree in-service radius was used throughout the project to lift materials to and from the rooftop. “Using the luffing jib allowed us to position the tower closer to the library structure, but, even still, most of our lifts were made close to tip radius,” says Brown. Arsene adds, “When the crane was not in service, the jib was set to a 65-degree radius to allow it to slew without hitting any of the adjacent structures.” Meticulous planning led to flawless execution of crane installation for Leavitt and SBW. The city allowed the adjacent Homer Street to be closed to facilitate installation. “Using a 300-tonne (350-ton) capacity mobile crane, we installed the tower, counter jib and apex on day one,” recalls Arsene. “On day two, we installed the jib and counterweight. It was a very smooth setup, and we were done in about 1.5 days.” Throughout the demolition phase, the crane was kept busy daily removing large structural pieces and concrete from the rooftop. Choosing the tower crane for this project gave work crews more flexibility with material removal. As work transitions to the reconstruction phase, the crane will be used to hoist large building materials and full concrete buckets from street level to the 8th and 9th floors. The largest and heaviest planned lifts will be the two 12,000-pound (5.4-tonne) escalators, hoisted into position without dis-

Brown adds, “The type of crane we are using is proving to be key for our success, and the CTL 430-24 is working great for us and doing its job.” SBW was scheduled to wrap up its heavy lifts with the Terex tower crane by the end of 2017. “We’ll finish all the heavy lifting by December, and then we’ll have the smaller finishing stuff throughout the end of contract.”
Unique concrete base solves foundation problem
To further reduce project costs, SBW’s plan for the CTL 430-24 crane included a freestanding tower that wasn’t tied into the library’s structure. Originally, SBW planned on using an undercarriage strut mounting for the tower section. However, the optional base’s availability was limited and not available in Western Canada. SBW put its century-plus concrete fabrication experience to work and consulted with engineering firm TNAI Engineering Ltd. to construct a custom concrete base to serve as a tying point for the crane’s tower. TNAI came up with an ingenious way to anchor the crane in a manner that would not require it to be secured directly into the building’s foundation. Anchoring to the foundation would require cutting through the street-level membrane and closing the three-level underground parking structure. “You don’t know what type of utilities and electrical components you will run into when cutting into the membrane, and this could lead to significant expense and delays,” explains Arsene. TNAI’s engineering team came up with a “floating” X-shaped concrete base. “When reviewing the parking lot’s drawings, we found columns supporting the library’s parking structure that were built at a 32.8- x 32.8-foot (10- by 10-m) spacing, so we tied directly into those columns,” adds Arsene. The columns served as the anchor conduit to the foundation below the parking structure. The concrete anchor measured 6 feet (1.8 m) wide, and height along most of the cross section was 6.5 feet (2.0 m). The outside 4-foot (1.2-m) end segments of the structure anchoring into the columns were 8.5 feet (2.6 m) tall. “This, in essence, gave us 2-foot (0.61-m) spacing between the concrete end segments and grade at the centre of the X-shape to create the floating base required to properly disperse the load,” explains Arsene. By employing the solution, SBW saved time, lowered costs and allowed the parking structure to remain open during the year-long reconstruction project. “It was a pleasure working with SBW on this project,” concludes Arsene. “They have the expertise to find the solutions to successfully complete a challenging project like VPL, and they don’t shy away.”

Survey eye in the sky Automated drone surveys provide highly detailed view from above for site construction projects By Lee Toop, Associate Editor
t has been a relatively short few years since unmanned aerial vehicles – better known as drones – have moved out of the domain of the military and government, and down to the everyday consumer. In that time, one of the most enthusiastic industries in the adoption of this technology has been construction, which came to an early realization that aerial surveys of everything from buildings to gravel stockpiles could improve the way in which pit operators and contractors managed their businesses. Today, drone manufacturers are recognizing the importance of that industry as the technology is improved and designed for uses in construction. One company, Kespry, has taken a broad leap into site construction with several moves that have paired it with a venerable equipment manufacturer while also adding solutions to help gather and process information quickly and accurately. Today’s drones have come a long way from the first of these remotecontrolled vehicles that were intended for recreation but quickly found their way into commercial use, according to Kespry product marketing manager Jason Nichols. “A lot of commercial-based drones at the time were military-specific and had a lot of depth and detail in the resulting product that couldn’t scale to a commercial application,” Nichols said. “So, when the first consumergrade drone came out . . . everyday users looked at the drone as a tool to capture imagery.” People in the construction industry looked at the ability to fly the drone over an area and take pictures in the process, and realized that there were potential business uses for the imagery they gathered. “They may have gotten this drone for Christmas, and would bring it to the construction site and fly it. Then they’d realize while flying it that ‘hey, we can actually take progress photos, because this is great to document,’” Nichols said. 38

Construction companies found that useful for tracking the progress on a construction site, in case of situations like litigation and liability concerns, and equipment rental companies that wanted to track fleet usage and maintenance were also interested early on. That launched the aerial drone imagery wave in construction, and from there usage has expanded into a number of different applications. Kespry got involved several years ago on the aggregates and mining side of the industry, Nichols said, using overhead imagery to measure
>> february 2018
stockpiles and help work out volumes of aggregate on site. Sensors installed on drones were being improved constantly to expand beyond imagery and into providing a view of topography and volumetrics; that allows for the drone to essentially capture 3D models of a work site. “We came to the market with a really strong offering that provided a solution with a high-quality sensor allowing the data to basically extrapolate a complete 3D model of the site,” Nichols said. “Going into the aggregates and mining industry allowed us
to further refine our product . . . which meant we were increasing our positional accuracy, and that’s where the real benefit comes in for the construction environment.” Kespry’s newest drone technology incorporates post-processing kinematic (PPK) technology, which uses GNSS point data to help refine the information it gathers during flight. That provides what Nichols said is a highly accurate product once processed. “We have a high-resolution GNSS module on the drone itself, but to refine the accuracy down to 2 to 10
“With the Earthworks solution, we’re setting a standard for companies to accurately plan, bid and manage their earthworks projects. That enables the construction companies to think differently.” centimetres, you have to add another control, which is a base station on the ground,” he explained. “That fixed base station collects GNSS data while the drone is taking images with its GNSS-known data. At the end of the flight, both data sets are combined, and we use PPK, which allows you to really increase your accuracy at every point.” Drone surveys generate a lot of material for companies to work with; the latest effort by Kespry has been the introduction of solutions to help process and make use of that information, especially when it comes to earthworks projects. The goal is to provide contractors with all the information they need to bid on projects, as well as to help track and document the progress of their jobs. “With the Earthworks solution, we’re setting a standard for companies to accurately plan, bid and manage their earthworks projects,” Nichols said. “That enables the construction companies to think differently about how they can collect survey information, which empowers them to make decisions or collect the necessary information to get the project off on the right foot through the planning and bidding process with a survey-grade accurate solution.” Kespry has developed a wide range of tools that have been introduced into the Kespry Cloud; as information is gathered by the drone on site, that data is input to the cloud for processing, then made easily accessible to the customer afterwards. The results are detailed site plans that can be used for everything from haul road design to grade planning.
lers,’ then you hit a button on the iPad that says ‘launch,’ and the drone takes off. There’s no interaction from the operator, though they have a couple of fail-safes on a separate control box to return the drone home or emergency land. Once the drone completes the mission it lands, shuts off and automatically uploads the data to the iPad. Once it’s on the iPad, it’s automatically uploaded to the Kespry Cloud.” The goal is to keep potential user error out of the process and to gather as much data in as little time as possible, making the survey results usable by the customer immediately.
“Let’s say you fly a 30-acre site in about 15 minutes. You quickly export that data and can look at it within a few hours,” Nichols said. Survey data can be used in a number of ways through the new Earthworks solutions, Nichols noted, from general site data down to grades on certain locations. One tool can provide change detection information, for example, providing a snapshot of the changes in a certain site, or portion of a site, between flights. “You can see the cut and fill change from the day they started grading to halfway through the project, or from one week to the next, or day to day,” Nichols said. “They can see the change through a red and blue cut and fill map, along with quantities for the identified region or across the entire site.” A spot elevation tool allows for identification of heights of certain locations – if a customer is working on a building pad and needs to check on whether the elevation has reached grade, they can check that in the drone data. Alternatively, the 3D polyline tool provides a snapshot of details along specific lines, Nichols described. “It allows you to basically draw a polyline along any portion of the flight area; you can extrapolate the grade of that
line, or the different slopes or segments; you can get the total elevation change throughout and verify against your design plan, or check to see if that particular cut slope is at the design plan grade.” Other tools look at volumetrics, allowing for analysis of stockpiles, trench excavation and other features of a site, Nichols said. A vectorized PDF overlay can be used to compare against the design plans and ensure that the job is on track. Interest in the use of drones on earthworks projects has been high, and the addition of the new Earthworks tools is likely to grow it even more, Nichols felt. The company formed a strategic alliance with John Deere in early 2017 and has had strong interest from Deere dealers that have signed up as resellers. More customers have come aboard because of that agreement, and with the added Earthworks solutions that is likely to grow, Nichols said. “The feedback from our construction customers has been pretty amazing, and we’ve gotten some good stories from customers,” he said. “We did a webinar with customers recently, and they were talking about the different ways they’re improving their workflow through flying the drone – saving weeks of time.” HEG

Autonomous drone flights
One benefit of modern commercial drones is their ease of operation. Unlike those that require an operator to fly the vehicle using joysticks and a video screen, Kespry’s drone essentially flies itself. The operator indicates a section of the jobsite for the drone to survey using a tablet, and then it’s a matter of pressing a couple of buttons to get the process underway. “We provide a quick and easy way for any person, from an experienced surveyor down to the project manager, to fly the drone – it’s simple point and click mission planning on an iPad,” Nichols said. “You hit ‘start propel-

Broadband backup alarms restore peace and quiet in Alberta town
wenty minutes west of Calgary, you’ll find the (mostly) quiet town of Cochrane, Alberta. Cochrane is no sleepy backwater, though; it’s the province’s largest town and has been one of the fastest growing communities in Canada for several years. But the town’s construction efforts haven’t been music to everyone’s ears. Back in 2014, after sleepless nights disturbed by the “beeping” sound of construction vehicle backup alarms at nearby businesses, local resident Kevin Shier and some of his neighbours went looking for an alternative. “Over 1,000 people in our area were affected by the noise,” explained Shier. “Current bylaws prohibit industrial noise after 10 pm and before 7 am, but it wasn’t so much the loudness of the alarms, it was the permeating noise they produce. Even at low levels it disturbs your sleeping patterns. I have a friend who sold his house and moved from our neighbourhood because of it. This isn’t limited to one area of town. There is construction in every quadrant that affects residents.” The group’s search led them to “white noise” broadband sound backup alarms, which replaces the “beep” with a “shush” sound. As broadband sound is directional, it’s concentrated to a specific area alerting workers to vehicles in their immediate vicinity. In fact, the group was so convinced by the technology, they bought several alarms using their own money and gave them to the noisy businesses for testing. After the first business switched, several others in the town soon followed suit, and to date nearly 200 broadband backup alarms are in use by the Town of Cochrane’s fleet, as well as local businesses AllSpan, Spray Lakes Sawmills and Cochrane Landscape Supply. To cater to demand, a local supplier was needed to ensure a steady supply of backup alarms were available. Shier, through his company Bird’s Eye Technologies, Ltd., became a distributor for Brigade Electronics, the manufacturer of the white noise alarm system they had used. Following these successes, members of Cochrane’s council even pledged to amend the town’s bylaw to permit the sole use of broadband backup alarms in the town. However, two years on, no legislation had been passed. “With the past council we were told it was a simple change: a no brainer,” said Shier. “But after our community group met with the bylaw department, we were told that the town would not be proceeding with a noise bylaw amendment as it would be too hard to police with out-of-town contractors working in the town. The Council felt it would also preclude some vendors from bidding on jobs for the Town of Cochrane’s internal departments.” Shier debunks these reasons.
“If we don’t have a bylaw with specific wording, bylaw officers have nothing to enforce,” he said. “We all know of many areas where bylaws are ‘softly’ enforced to better our communities. However, without a ban on tonal alarms, we can’t even start the conversation with businesses. Local infrastructure projects for the Town of Cochrane are typically large, most exceeding $100,000, so changing to an alarm that costs $100 on a vehicle is not an onerous expense.” In addition, Shier’s role as the only local distributor has led to accusations of a vested interest on Shier’s part, something he strongly refutes. “There were three reasons I became a distributor,” he said. “First, no other supplier in Cochrane existed (which is still the case); second, the Town of Cochrane insisted local distribution was made available; and third, to be able to offer the technology at cheaper prices as most online retailers in Canada are marking them up two to three times over their purchase price. It doesn’t matter where they purchase them. It matters that it gets done.” Despite the halt in progress, Shier’s efforts continue, and he hopes the new council will support bylaw changes. “As community members, it isn't our job to police noise in the town. And without a bylaw, it isn’t the Town’s job either. Without a bylaw, we can't manage noise pollution the way the community wants. We know we need to offer win-win ideas – not force our demands upon businesses. This means educating them about the negative health effects, and demonstrating that they have viable options without

Heavy-duty bbs-tek white noise backup alarms (right) are ideal for plant, quarry and construction equipment and environments with high ambient noise. sacrificing safety. The bylaw amendment would assist with the followup and education pieces, allowing the conversation to start.” Frustratingly, the Town just recently issued a contract to build a new road close to residential areas. Not a single vehicle on that contract is using a broadband sound alarm, so the original annoying backup alarm noise has returned to the same area of Cochrane as before. But Shier isn’t despondent. “Change starts with citizens. The community belongs to its people,” he says. “We don’t know of any other towns which have tackled these issues. I’d like anyone else affected in other towns to contact me about the action they’re taking. Safety and silence aren’t mutually exclusive, but most operators and communities don’t know that.”

PEOPLE. PASSION. PERFORMANCE.
Guardian Angel Elite Series visibility device OSHA reports indicate that 16.8 percent of construction deaths are due to the combined hazards of being struck by an object and being pinned by machinery or equipment. Many of these deaths could have been prevented if the workers had been equipped with more advanced personal safety equipment that exceeded Class 3 Reflective Apparel regulations that dictate a 1,280-foot visibility distance. The LED Elite Series device can be seen for up to two miles – eight times as far as Class 3 Reflective Apparel standards of 1,280 feet. That can be the difference between life and death, especially when considering that distance can be closed in only 13 seconds by a vehicle travelling 65 mph – a blink of an eye to a distracted driver. Guardian Angel’s Elite Series can be mounted to people and machinery to create a 360-degree halo of illumination to alert everyone in a two mile radius to its presence. If a device is attached to a machine that’s backing up, workers within the halo’s reach will be able to see the light and position themselves safely, even if their backs are initially turned to the oncoming machine. Conversely, the machine’s operator will be able to see the worker’s Guardian Angel device beacon, even if they cannot see directly behind the machine. The Elite Series is constructed of a virtually indestructible polycarbonate casing and yet weighs in at three ounces. The device’s light weight means that it can be mounted anywhere on a person’s body without creating an uncomfortable distraction. Since different jobs call for different places and positions that a worker may need to work in, the Elite Series also features a built-in rare earth magnet as well as several other mounting accessories to make different mounting positions achievable quickly and with ease.
Location Badge The wearable Redpoint real-time location badge tag can track and communicate to employees – no matter where they are on the jobsite. Accurate to within 20 cm, the badge operates on ultra-wideband and is capable of detecting and logging the wearer’s precise location up to 52 times per second. The badge has an easy-to-read e-paper display that communicates the badge’s status in real time, as well as alarms, text messages and other identifying information sent from the server. Using Redpoint’s web-based RTLS management platform, SiteWise, users can generate alerts from the server to send to the badge of an individual or to the whole workforce. These text-based alerts also trigger an audible alarm as well as a visible strobe from the LED. The Redpoint badge has an emergency call button and messaging display. The badge is rechargeable, using a wall-mountable multi-charger, and supports real-time tracking with sub-meter accuracy. When integrated with SiteWise, the badge gives users total visibility of jobsite activity and provides critical safety and efficiency metrics. The cloud-based server logs the badge’s position reports, as well as alarms, which can be compiled and analyzed. The badge can be fully provisioned, managed and programmed remotely overthe-air anywhere within the ultra-wideband mesh-network coverage area without the need for complex network integration. The badge is a ruggedized workforce management and safety tool, designed to withstand the wear and abuse of even the harshest jobsite.

Ford introduces first-ever
power stroke F-15O F
ord is providing diesel truck fans with a reason to celebrate the start of 2018 with the introduction of its first-ever F-150 Power Stroke diesel. The new truck will be available in the spring, and joins the larger FSeries Super Duty trucks that have featured Power Stroke motors for some time. The new 3.0L diesel engine providing the power for the F-150 is targeting 30 mpg on the highway, along with strong towing and payload capacity. “For every truck owner who wants strong fuel economy while they tow and haul, we offer a new 3.0L Power Stroke V6 engine that dreams are made of,” said Dave Filipe, vice president, global powertrain engineering with Ford. “The more you tow and the longer you haul, the more you’ll appreciate its towing and payload capacity and how efficient it is at the pump.” The addition of the 3.0L Power Stroke diesel means there are now six engine choices for F-150 customers. The highly anticipated new diesel shares proven commercial-grade technology with F-Series Super Duty’s larger 6.7L Power Stroke. The same Ford powertrain team behind the Power Stroke for Super Duty trucks since 2011 designed and engineered this all-new 3.0L V6 to the specific needs of North American F-150 customers who tow and haul frequently. The V6 generates 250 hp and 440 lb.-ft. of torque. Peak torque comes at 1,750 rpm with strong torque delivery continuing throughout the rpm range, ideal for towing or hauling heavy loads over long distances. This new V6 diesel features the same compactedgraphite iron block material construction and forgedsteel crank used in the 2.7L EcoBoost engine for added strength and durability along with reduced weight. For greater responsiveness and reduced turbo lag, the Ford truck team chose a high-efficiency variablegeometry turbocharger. A common-rail fuel injection system precisely optimizes performance and fuel efficiency, while a high-pressure 29,000 pounds per square inch injection calibration enables smoother, quieter operation with reduced emissions. 44

Dual fuel filters are added for improved breakin, while a cast-aluminum oil pan and two-stage oil pump mean reduced parasitic loss and improved fuel efficiency.
Engineered to tow under grueling conditions
Engineering the most efficient F-150 towing machine ever is enabled by F-150’s high-strength, military-grade, aluminum-alloy body, introduced in 2015. This construction lightened the load by 700 pounds, allowing engineers to invest in additional technologies to further improve towing and payload capability, as well as offer greater fuel economy, even when towing. For 2018, stronger axles coupled with the fully boxed, high-strength steel frame add further robustness. The Ford truck team paid particular attention to extreme driving conditions when engineering the
all-new 3.0L Power Stroke diesel, which features a premium mechanical engine-driven fan and dual radiator shutters for improved high-temperature, high-altitude performance – a key advantage versus the electric cooling fans used with other engines, Ford states. “We know that diesels with electric cooling fans have to dial back on power under extreme heat and altitude, so we decided on a viscous-controlled mechanical fan that has the capacity to move much more air across the radiator and intercooler in extreme conditions,” said David Ives, Ford diesel engine technical specialist. “This gives F-150 Power Stroke owners more power and more passing capability in harsh conditions.” In more moderate driving and towing conditions, the F-150 engine control system backs off the fan load through a viscous coupler, closing down the two radiator shutters for improved aerodynamic efficiency and reduced parasitic engine loss. Calibrated specifically for the Power Stroke diesel’s low-end power and torque curves, a standard SelectShift 10-speed automatic transmission maximizes shift points and gear ratios to optimize power, low-rpm torque and efficiency. This transmission can non-sequentially select the right gear ratio based on need. To help reduce fuel consumption and vehicle emissions during city driving, Auto Start-Stop also comes standard. In testing, the F-150 equipped with the new diesel engine climbed 13 miles at a 6 percent grade in temperatures in excess of 100 degrees – maintaining consistent power output throughout. The 3.0L Power Stroke is available for both 4x2 and 4x4 F-150 pickups. Retail customers can choose this engine option for 2018 F-150 Lariat, King Ranch and Platinum edition SuperCrew trucks with either a 5.5-foot or 6.5-foot bed configuration, and SuperCab trucks with a 6.5-foot bed configuration. For fleet customers who use their truck for work, the 3.0L Power Stroke diesel engine will be available on all F-150 trim levels with SuperCrew 5.5-foot or 6.5-foot bed configurations and SuperCab trucks with a 6.5-foot bed.

The eTorque mild hybrid system replaces the traditional alternator on the engine with a belt-driven motor generator unit that performs several functions. The motor generator unit works with a 48-volt battery pack to enable quick and seamless start/ stop function, short-duration torque addition to the engine crankshaft in certain driving situations and brake energy regeneration, which improves responsiveness and efficiency. With the engine running, eTorque’s motor generator unit feeds 48-volt current
to a 430 watt-hour lithium-ion nickel manganese cobalt graphite battery. The small-suitcase-sized, air-cooled battery pack mounts to the rear wall inside the Ram 1500’s cabin. In addition to spinning the engine for restarts, the eTorque unit also recaptures energy during deceleration and braking to feed charge to the battery pack. Ram 1500 is available with the 3.6L Pentastar V6, which generates 305 hp
and 269 lb.-ft. of torque, and is the standard engine in most trim levels for 2019. For more muscle, the 5.7L HEMI V8 is also available, offering 395 hp and 410 lb.-ft. of torque in a smooth, broad power band that avoids the hesitation and peakiness that can come from turbocharged engines. Every 2019 Ram 1500 is equipped with a fully electronic TorqueFlite eightspeed automatic transmission with a wide spread of gear ratios.

ERY DAY. V E . L U A H Y R MANCE. EVE
A zero-emission Kenworth T680 day cab equipped with a hydrogen fuel cell was displayed at the 2018 Consumer Electronics Show (CES). The vehicle is part of the Zero Emission Cargo Transport (ZECT) demonstration project managed through Southern California’s South Coast Air Quality Management District (SCAQMD). The Kenworth T680 day cab’s fuel cell combines compressed hydrogen gas and air to produce electricity with only water vapour emitted at the tailpipe. This electricity can power the dualrotor electric motor to move the truck, or it can recharge the lithium-ion batteries for use later. The hybrid drive system manages the power from the fuel cell to and from the batteries, as well as the traction motors and other components, such as the electrified power steering and brake air compressor. The hydrogen fuel-cell-based Kenworth T680 will have an initial range of 150 miles, which makes it ideal for short haul and port operations. With a dual-rotor traction motor output of 565 hp, the truck is capable of carrying the legal gross combination weight of a Class 8 vehicle.

rigid hauler range V
olvo Construction Equipment will enter the rigid hauler market with its own Volvo brand of rigid haulers in the second quarter
of 2018. The development of the new fourmodel range has relied heavily on the longstanding rigid hauler expertise of Volvo CE’s subsidiary Terex Trucks, combined with the technological strength of the Volvo Group. The range, which will initially be launched in less regulated markets, consists of the 45-ton R45D, 60-ton R60D, 72-ton R70D and the flagship 100-ton R100E. The E-Series R100E is a completely new Volvo CE 100-ton (95-tonne) rigid hauler that combines a wealth of market and customer knowledge with proven components, new technologies and a striking new design – all providing a cost-effective and productive solution to fulfill the
needs of today’s mining and quarrying customers. Based on the existing and wellproven Terex Trucks TR-Series, development of the D-Series R45D, R60D and R70D Volvo rigid haulers follows an in-depth engineering review, ensuring that the machines meet the standards expected from Volvo products in their target markets and segments. Improvements include greater visibility and safety systems, along with Volvo technical support and branding. As a result of the launch of the Volvo-branded rigid haulers, production of Terex Trucks rigid haulers will, over time, cease. “Our purchase of Terex Trucks in 2014 was a strategic decision that allowed Volvo to offer customers a rigid hauler option,” says Thomas Bitter, senior vice president of the Marketing and Product Portfolio
(MaPP) function at Volvo CE. “Since then, we’ve been working to design a completely new rigid hauler that builds on Terex Trucks’ 84-year heritage, while also incorporating Volvo CE’s industryleading technology and core values of quality, safety and environmental care. Today we move to the next stage, and the new Volvo machines, especially the E-Series R100E, are the outcome of this work. We’re confident that they will impress customers working in the mining and quarrying segments.” The all-new flagship R100E has been designed to meet customer demands for a rigid hauler that delivers high performance and productivity, low total cost of ownership, easy serviceability and good operator comfort. With its high capacity and hauling speeds, new V-shaped body, efficient hydraulics, intelligent monitoring systems and
operator environment, the R100E will help customers move more material in less time. “Terex Trucks’ rigid haulers are known for performing well in tough conditions, while also being easy to maintain and delivering low cost of ownership,” says Paul Douglas, Volvo CE’s vice president of Rigid Haulers and Terex Trucks. “Our proven design has provided a strong DNA on which to help develop Volvo CE’s innovative entry into this product line. The new E-Series R100E is a completely new machine that delivers stability, a long service life, high profitability, durability and comfort. And, moreover, it’s quick and simple to operate and maintain.” The new Volvo-branded rigid haulers will be manufactured at the rebranded Volvo Motherwell production facility in Scotland and sold exclusively through the Volvo dealer network.
Next-generation Silverado weighs less and offers more cargo volume Chevrolet has introduced the next-generation Silverado, exactly 100 years after the brand delivered its first trucks to customers in January 1918. The all-new Silverado has what Chevy says is the most functional bed of any fullsize truck, weighs up to 450 pounds less for increased performance, and offers a broad range of trims and engine/transmission combinations. The truck is larger than before, including a wheelbase that is up to 3.9 inches (100 mm) longer and an overall length that is 1.6 inches (41 mm) longer, enabling both more cargo volume and more interior room for all cab lengths. It’s also lighter, weighing 450 pounds (204 kg) less than today’s truck when comparing crew cab V8 models. The 2019 model offers the most cargo volume in every bed length, with the short-box offering 63 cubic feet of volume. Most of that volume was created by widening the maximum width of the bed floor nearly seven inches. As before, the Silverado has a roll-formed, high-strength steel bed floor. For 2019 a higher-grade steel is used. The Silverado will be available with six engine/transmission combinations, 48

giving customers more combinations of performance, efficiency and value to best fit their priorities. This includes new 5.3L and 6.2L V8s with Dynamic Fuel Management that actively shuts off any number of cylinders, in a variety of combinations, depending on immediate needs to optimize fuel economy. The result of this industry-first technology is instant power when called for, and impressive efficiency. The Silverado will also be available with an all-new Duramax 3.0L inline-six turbo-diesel. Both the 3.0L diesel and 6.2L engines are paired with a new HydraMatic 10-speed automatic transmission as well as start/stop technology to improve fuel economy for optimum performance and efficiency. The interior design was also strongly influenced by customer feedback. Because truck owners use their vehicles for both hauling cargo and transporting people, customers’ top priorities were more comfortable seating, more interior cargo storage and more functional, easy-to-use controls. Accordingly, the cab has been stretched, with crew-cab models now offering three inches of additional rear-seat legroom for an impressive 44.5 inches of front legroom and 43.8 inches of rear legroom.

Piling, Drilling & Foundations
Building big, digging deep
Contractors face geological and logistical challenges in effort to support Western Canada’s tallest tower in downtown Edmonton By Lee Toop, Associate Editor
renewal is taking place in downtown Edmonton, Alberta, one that has taken an old warehousing area and is turning it into a shining new retail, residential and commercial hub for the community. The ICE District is a collection of towers being constructed around Rogers Place, the new home of the Edmonton Oilers; when completed, one of those towers will be the tallest in Western Canada. Building any large structure in Edmonton is a tough job due to the geological makeup of the area; building a 60-plus story structure like the Stantec Tower is even more so, requiring a strong – and deep – foundation. For PCL, the general contractor for the ICE District project, an accelerated schedule and logistics made for a challenging project. ICE District is a 25-acre space in the heart of Edmonton that, when complete, will include the arena, 300,000 square feet of retail space and 1.3 million square feet of offices – as well as condo developments and an upscale hotel. It’s an ambitious project, and one that since it began has been on an 50

ambitious timeline. “The buildings were being designed as we were breaking ground, and a lot of the programming for the buildings was being established while we were getting into the construction,” related Myke Badry, PCL senior project manager. Work began on the site in 2014, and as the planning progressed, so did the size of the buildings. The Stantec Tower and JW Marriott hotel reached a point where a more robust foundation was going to be needed than originally planned. “When the building started to reach heights upwards of 60 floors, we started getting into a situation where the ground pressure couldn’t support the towers anymore and we had to work on a pile solution,” Badry said. “So this is all happening while we were living in a hole . . . when we were about halfway down the hole we got directions from the design team to mobilize for caisson foundations.” Ground conditions on the site were, to say the least, interesting. The site had, over time, been built over, and in some cases the previous struc-
tures had been left on the site. “At the time we got to the site it was a gravel parking lot with one building on it. When we were excavating it, we had to excavate the remnants of a lot of old buildings backfilled into the hole when the warehouse district was demolished several years ago,” Badry said. Below that, though, the team reached Edmonton’s challenging geological underside: medium plastic clay and shale extending down some 75 metres below the site before reaching bedrock. Caisson foundations were the best option for providing the support needed by the Stantec Tower and its neighbouring hotel; the best option for drilling and installing the caissons, PCL decided, was to call in Bauer Foundations.
Deep drilling requires expertise
According to Badry, Bauer had the global experience and capability to get the job done in short order, as well as the equipment for what was a very deep drilling job.
The pile depths went down to 75 metres, which is not normal anywhere in the world. To complete the work, Bauer brought in their largest machine, the BG50 – the first time this machine was used in Canada.
“The pile depths go down to 75 metres, which is not normal anywhere in the world, and to add to that the piles had to be installed in an 18-metre-deep hole,” said Allan Bowers, Bauer Foundations Canada operations manager. “We’re also talking about reasonably large diameters – in this case, at 75 metres deep, we had 1,850-millimetre diameter piles, so we had to bring in the biggest rig that Bauer manufactures, which is the BG50, a 260-ton machine.” Before tackling the actual drilling, however, Bauer’s crews had to deal with a bigger challenge: getting to the site. Located as it was in the middle of a busy city, the ICE District project is congested to begin with. As Bauer mobilized its equipment, construction was going on all the way around the pit, making it doubly difficult to access. “On the site itself, the towers that we piled are the only elements of the project that actually had foundation piles – the other elements are all on straight foundations. So, around our working area there was a car park being built adjacent and tower cranes in close proximity . . . the logistics of getting our equipment and materials in and out had to be managed,” Bowers said. “The arena was also under construction just to the north of our site.”
Close quarters coordination
That meant tight coordination with other ongoing work around the pit for movement of equipment in and out. It also meant that, with no ramp
into the work site, the Bauer rigs needed some heavy lift cranes to get into the pit, and came with some assembly required. “We had a 260-ton machine with 38.5-metre masts that had to be broken down into small enough parts to be lifted into an 18-metre excavation,” Bowers said. “Obviously, it then had to be assembled at the hole, and at the end of the job we had to then dismantle it and lift it out. Lowering in and lifting out both required road closures, had to be done over weekends, and so forth.” Once the machines were in the pit, approximately a week was needed to reassemble them before work could begin; at the end of the project, they had to tear them down and lift them out again. “All of this happened in the winter,” Bowers added. “The work carried on right through the winter, in Edmonton, working 24 hours a day, six days a week.” Once the drills were in place, Bauer drilled test piles that helped finalize the design. Because of the sheer size of the structure above and the loads faced on the piles, the eventual decision on how many piles were needed took some time to complete. “The tower was going to be around 250 metres high when it’s finished, so obviously the loads were fairly sizeable,” Bowers said. “We did a test pile to try and see if the design could be validated . . . that indicated that the soils were poorer than expected.”
200 cubic metres of concrete were pumped into each 75-metre caisson pile.
Bauer’s largest machine, the BG50, was equipped with a special Kelly bar to achieve the necessary depths. Piles are deepest Bauer has ever done in Canada
The completed design required 72 piles 1,500 mm in diameter and 52 metres in length for the Marriott tower, and 73 piles 1,850 mm in diamter and an impressive 75 metres deep for the Stantec Tower. “Those were the deepest piles we’ve done in Canada. We’ve done more than 100 metres elsewhere in the world, so we knew we had the equipment and experience within the business,” Bowers said. “We brought in the largest machine available within the group anywhere in the world. We had to have a special Kelly bar to get those depths – normal Kelly bar rigs are down to 40 metres deep. We were able to install these piles without the use of Kelly extensions, which meant the drilling time was faster than if we’d had to use smaller machines.” The BG50, which was used for the first time in Canada, and its higher torque were invaluable in drilling to depth, even with occasional surprises when more solid rock was encountered during the bores, Bowers noted. With the caisson piles set to depth, the next challenge came with pumping each bore full of concrete. Logistics again became the limiting factor.
Each of the long piles required a pour of about 200 cubic metres of concrete. Bauer experts worked with the concrete supplier to get a concrete mix that would work with long pour times and the winter conditions – since the pours had to be done overnight from street level using a tremie system. “The concrete had to be brought in when the traffic on the route from the concrete mix plant was not going to be congested – trying to do it during the day would cause issues with the concrete deliveries. We needed that concrete there as quickly as possible,” Bowers said. In all, PCL, Bauer and other contractors – with around 60 employees total on the caisson installation, and nearing 1,000 as tower construction got fully underway – put in about six months’ worth of 24-hour work days to ensure that the ICE District project stayed on time. As of February 2018, construction is still ongoing but on target. “For the Stantec Tower, we’re on the 32nd floor of 69; the other tower, the J.W. Marriott, is on the 50th floor of 54,” Badry said. “They’re both targeted for occupancy in the third quarter of 2019.” HEG
