Canada Piling Industry News Jobsite premiere of Liebherr’s largest duty cycle crawler crane Liebherr’s HS 8300 HD, the world’s largest duty cycle crawler crane, recently had its premiere on a jobsite in Bavaria. It is the first Liebherr crane for the construction machinery market to be equipped with the innovative hybrid drive Pactronic®. The HS 8300 HD combines the traditional robust design of Liebherr’s range of heavy duty cycle crawler cranes with state-of-theart-technologies. Thus, the efficiency of the machine is significantly improved during practical application. For a further increase in performance the crane is fitted with hydraulic free-fall winches offering approximately 50 tonnes of line pull. Since the end of 2014 the company Wanner & Märker has been using the new duty cycle crawler crane for gravel excavation in one of their three quarries. The jobsite is located in the south of Germany, close to the city of Ingolstadt. The proportions are remarkable. The machine, with an entire weight of more than 350 tonnes, operates on the site with a 44-milimetre-long main boom and a dragline bucket made by Rädlinger. The digging depth is approximately 26 metres, the unloading height about 15 metres. Apart from the dimensions of the HS 8300 HD, which dwarf other duty cycle crawler cranes in comparison, the machine impresses with its innovative hybrid drive allowing an increase in turnover at the jobsite by up to 25 per cent.
Powerful hybrid drive Pactronic® The HS 8300 HD is the first construction machine on the market to be equipped with the Pactronic® system developed by Liebherr. This innovative hybrid drive based on hydraulics offers both economic and ecological advantages. Surplus energy is stored and subsequently regenerated so increasing the material handling capacity while at the same time significantly reducing fuel consumption. The hybrid drive is already a proven technology. It has been used in Liebherr’s mobile harbour cranes since 2010 and has contributed to the consolidation of the world market leader position of this product line. The proven technology of the hydraulic accumulator ensures low maintenance requirements and maximum 8 PIC Magazine • June 2015
reliability. The reduced energy consumption considerably reduces emissions therefore causing much less environmental pollution.
Extended service life In the development stage special attention was paid to an extended service life of the duty cycle crawler crane. Therefore, the steel fabrication of the basic machine is extremely solid and critical points were reinforced using extra high-quality materials such as carbon fibre. Furthermore, special production methods, including the use of automated welding robots, increase the machine’s service life even under extreme operational conditions. Apart from dragline operation the HS 8300 HD is suitable for various other material handling jobs. The machine can, for instance, also be equipped with an orange-peel grab and a clamshell. As other Liebherr machines the HS 8300 HD incorporates many components and system solutions developed by Liebherr. Apart from the homogeneous system this also guarantees high availability of spare parts within the Liebherr service network. The proven Litronic control system, which is based on CANBUS technology and includes all control and monitoring functions of the machine, belongs to the standard equipment of the HS 8300 HD. The Litronic system works reliably even under extreme weather conditions and vibrations.
Pile Dynamics completely revamps its Pile Driving Analyzer® system Pile Dynamics has recently announced the release of a new model of Pile Driving Analyzer® (PDA) System, the PDA-8G, billing it as the culmination of a complete redesign effort
of the most widely employed system for Dynamic Load Tests of any type of deep foundation. Like previous PDAs, this eight generation model performs the test normalized by the American Society of Testing and Materials standard ASTM D4945. The test, which for many decades has been accepted as an alternative for static load tests in more than 100 countries around the world, takes place either during pile driving or when a substantial mass impacts a non-driven pile. At each impact the Pile Driving Analyzer takes data obtained by sensors attached to the pile and calculates bearing capacity and other quantities. In the new PDA-8G these quantities number more than 230: a trove of information to the geotechnical engineer, who doesn’t even need to be at the job site. With this new model Pile Dynamics made its SiteLink® technology easier to use. SiteLink transmits test data in real time from the field to an office computer at an alternate location. The majority of engineers will probably still use the PDA-8G in the field, however. For them, Pile Dynamics made a tablet-like PDA that is thinner than previous models, light, ergonomic, and with a high visibility touch-screen display that responds to gesture controls like swiping and pinch-tozoom. The PDA-8G is being offered with either four or eight universal channels of data acquisition, all compatible with both cabled and wireless sensors. This enhancement from previous models is of particular interest to those who test large diameter shafts. Data transfer from the sensors to the PDA is extremely fast, suitable to test piles driven with high blow rate hydraulic hammers. The PDA-S software includes extensive data input help and output customization, and two real time capacity cal-

Atlas Copco featured onemegawatt QAC 1200 generator at POWER-GEN® International Atlas Copco QAC 1200 generators produce one megawatt of predictable power. They can be used in prime power or critical standby applications in a multitude of industries, including construction, mining, and oil and gas. Operators also can parallel as many as 16 QAC 1200 generators for greater dependability, versatility, and reduced fuel consumption. The generators feature plug-and-play technology that allows users to connect the units with a single cable. Once this is done, they can connect the power cables to a common bus, set the desired parameters, and the generators automatically synchronize. This enables the units to automatically power down or up, depending on the load requirement, which helps save fuel. In addition to reduced fuel consumption, paralleled QAC 1200s provide more dependable power than multi-megawatt generators. Relying on a single multi-megawatt generator for primary power puts the worksite and budget at risk if an outage occurs. By comparison, running multiple, one-megawatt generators that are paralleled keeps power supplied to tools and machinery even if one unit goes offline. Atlas Copco engineers the QAC 1200 into custom, 20-foot enclosures with the same footprint and form factor as ISO containers. This ensures the units are structurally sound and can accommodate features that would otherwise weaken the integrity of standard shipping containers such as larger openings for maintenance access and control panels on the outside. The enclosure also helps minimize engine noise to 75 dBA at 23 feet, which makes it an ideal generator for sound-sensitive appli10 PIC Magazine • June 2015
cations near hospitals, museums and schools. The International Convention for Safe Containers (CSC) also approves the 20-foot enclosures, which means cargo ships, railroad cars and semi-trailers can readily transport the QAC 1200 generators. The QAC 1200 features a Cummins QST30G5 diesel engine that is EPA Tier 2 certified and provides 1158 kVA/926 kW prime power rating (60 Hz). With this fuel-efficient, electronically-governed engine, the integrated fuel tank provides a minimum run time of eight hours. Engine fluids are plumbed to the edge of the skid on the QAC 1200 to eliminate the hassle of maneuvering pans into the interior space. The standard, spillage-free base frame is sized to contain 110 per cent of all the machine’s fluids and fuel, which safeguards the site and protects the environment. Atlas Copco also offers optional coldweather packages for the QAC 1200 generators. They include alternator heaters, coolant heaters and battery chargers to ensure dependable starts and operations in cold climates.

Science World’s piling project reaps benefits of BIM By Melanie Franner prototype – that’s where the real value comes into the equation.” The use of BIM-enabled software allows users to access and manipulate data throughout the various stages of construction – from the design through to facilities management. “BIM is really about trying to take the digital prototype from the manufacturing side of the industry and applying it to the architectural and owner side,” adds Rayner. “We can do the estimating, the time analysis, scheduling, ordering, etc. – all from a 3D prototype. This allows us to resolve any potential problems before they occur – and well before getting to the actual job site.” Geraldine Rayner, vice-president of Consulting Services, Summit BIM Consulting Ltd.
Traditional paper-based drawings may be the status quo for many in the Canadian construction industry but some leading-edge innovators have made the transition into the digital world. Building Information Management (BIM) has already taken root in some sectors and is proving to be an invaluable tool – even in the piling industry.
BIM by design “I’ve been using BIM for about eight or nine years now,” states Geraldine Rayner, vice-president of Consulting Services, Summit BIM Consulting Ltd. “Unfortunately, the adoption rate across the industry has been patchy at best.” According to Rayner, there is still a lot of confusion around the concept of BIM. This has led to some hesitation and a slow adoption rate. “BIM is a process of utilizing digital technology to convey information rather than paper,” she says. “Some in the architectural community are using BIM to produce black and white traditional drawings. A small number of people are using it as a tool to create a digital 14 PIC Magazine • June 2015
Key benefits There are many significant advantages inherent in the use of BIM, according to Summit BIM Consulting. These include: collaboration, cost certainty, facility asset management, improved quality, informed decision making, increased productivity, reduced FM cost, reuse of data, reduced changes, reduced risk, and sustainable design analysis/visualization. At the end of the day, BIM can reduce a project’s overall costs and improve efficiencies along the way. A report from the Construction Task Force
in the United Kingdom, Rethinking Construction, cites recent studies that suggest: up to 30 per cent of construction is rework; labour is used at only 40 to 60 per cent of potential efficiency; accidents can account for three to six per cent of total project costs; and at least 10 per cent of materials are wasted. “More than 30 per cent of the cost of a project is tied up in inefficiencies, delays and wastage,” states Rayner. “As we learn to use BIM effectively, we can reduce this percentage. But the potential exists to eradicate it completely.” Rayner describes BIM as a number of different tools. Each segment of the construction industry has its own tool but there is a common “language” that allows everyone to talk to each other. The information is entered once and then used repeatedly throughout the different phases of the project. It may involve a bit more work at the front end but that extra work will reap digital rewards throughout the entire project – even once that project has been handed to the owner in the facilities and operations management phase. A 2013 McKinsey Global Institute report on infrastructure productivity states that: “A key source of savings in project delivery is investing heavily in early-stage project planning and design. This can reduce costs significantly by

canadA | U.s. | international “The cost of change orders on a project can be about 10 per cent,” says Rayner. “Owners have to bear that cost. Our clients have all seen a reduction in the number of RFIs and the number of change orders associated with their building projects. They have seen some definite benefits, like having all of the building’s information data go straight through to building, maintenance and operations departments, without needing to be re-entered along the way.” Other important elements that BIM brings to light – before actual construction – are soft and hard “clashes”. The former refers to having enough space within a certain area of the building to do the required work and the latter is used to identify actual obstructions, such a

Piling work proves premise When consulting structural engineering firm, Bush, Bohlman & Partners, was awarded the $35-million renovation project to Science World in 2011, they didn’t hesitate to make use of Revit Structure within a BIM process to create a 3D digital version of the existing building structure. That foresight has paid huge dividends along the way. Science World at TELUS World of Science is located in an iconic geodesic dome, which was originally built for Expo ’86 as a temporary structure. The building is close to 30 years old – and still going strong. This is due, in part, to the massive structural engineering work completed in 2011. “Part of our work in 2011 was to do a seismic assessment and retrofit of the original Expo building podium structure utilizing 3D dynamic analysis,” states Michael Sullivan, CTech, a Structural Technologist/BIM Specialist with Bush, Bohlman & Partners (consulting structural engineers), who adds that the podium and base structure support a 47-metre high geodesic dome and was built partially over water. “The existing building structure used a com-

plex and congested pile-supported foundation system – with battered piles at major columnsupport locations. During this expansion project, over 400 – or 98 per cent – of the existing piles were modelled digitally,” he explains. Extensive new piling work was required on the Science World podium base structure’s existing foundation system. Large steel momentresisting frames were centred along the radial gridlines on the west side. The frames were anchored by custom-cruciform shape, wideflange columns. The steel columns were then supported by the new pilecaps keyed into the existing concourse level such that no additional gravity or seismic loads were transferred back to the existing structure. Bush, Bohlman & Partners used Revit software to determine where the existing piles were located so that workers could cut through the podium’s deck structure to drive the new piles. “We used the modelling software initially to lay out the locations of the existing piles and to where to cut through the existing deck to drive the new piles,” explains Sullivan, who adds that the new piles were designed to support the new expansion seismic retrofit and relieve the load from the existing structure. “We cast the pile caps directly into the holes cut through the existing deck structure.”

The west side of the podium structure required over 40 new concrete-filled steel piles, of which 30 were battered piles. The former were 508 centimetres in diameter and 15 metres long. The latter were 610 centimetres in diameter and 15 metres long, each with a 55 milimetre diameter Dywidag rock anchor. All
of these piles had to be driven from a rig set up on a barge on the False Creek side of the building. “The battered piles were part of the seismic system upgrade,” explains Sullivan. “Where new columns bear on an existing concrete beam, we spanned new reinforced concrete beams underneath that existing beam and placed pilecaps with battered piles, in groups of three, on either side to transfer the new column loads off of the existing deck support beams.” The renovation and expansion work on the east side of the podium wasn’t as extensive and didn’t require seismic upgrading to the existing previous expansion completed in 1988. A total of 20 new piles were driven to support the new entry sequence and augment the structure’s existing foundation system. “The use of Revit software in this project was huge,” states Sullivan. “It facilitated the installation of the piles relative to the dome and to the existing piles. The facility remained open during the work so being able to know the exact locations of where to cut through the deck was invaluable. We used Revit to lay it all out before we started the actual work. Plus, the existing battered piles were slanted and angled in different directions. We used Revit to lay out where each new pile could be located without running into the other piles already there.”
More to come Although the benefits of using BIM tools were well established – and capitalized upon – during the 2011 renovation project, it looks like it may be a case of where BIM just keeps on giving. Last year, TELUS World of Science
canada | U.s. | international again approached Bush, Bohlman & Partners. “They asked us to conduct an assessment of the dome and piling foundation structure because the facility has long outlasted its initial lifespan as a temporary structure,” states Sullivan. “We’ve been tasked to review all of the existing structure with the goal in mind to make it last many more years.” In 2014, Bush, Bohlman & Partners completed the condition assessment study of the entire existing building and expansion base structure, which involved going out in a small boat at low tide and doing an extensive visual study of the underneath of the existing base structure. This study revealed the damaging effects of salt water on the existing steel piles and these were categorized within the 3D digital model to create a comprehensive condition assessment report of the base structure. This information will be used to facilitate any future remediation work. “We categorized the piles according to the severity of their condition and then colourcoded and scheduled them for easy identification,” states Sullivan. “And we can provide all of that detailed information up front so

that contractors know exactly where and what needs to be done to provide more accurate bids.” Fortunately, Bush, Bohlman & Partners already had completed a lot of the preliminary work required in the condition assessment study – thanks to their use of BIM on the 2011 renovation project.
“It does take longer to digitally model a building, especially an existing structure like Science World,” concludes Sullivan. “But we’re certainly pleased that we put the energy in to do it in 2011. Not only did it prove advantageous back then but now, with this new assessment four years later, it will make our work that much easier.” n

Wearing the right clothing on the job can mean so much – your comfort, your happiness, and even your safety By Emily Pike
Working outside in the heat of the summer is something that office workers pine for, but those in the sun know it can come with its own set of problems. Sunburn, overheating, sweaty clothes, and not having the right gear for a change in weather can all make you miserable during the workday. When it comes to getting the right clothes for the job, quality is an important consideration. In cases where the employer supplies the worker’s personal protective equipment, quality garments mean they replace them less and workers have the confidence in knowing they’re protected. David Finlayson, North American product manager for Helly Hansen Workwear, outlines the types of questions to ask when buying: “Will the reflective striping work after it has been washed a few times? Will background colours continue to stand out when a garment is dirty? Will fire-resistant treatments wash out? Do I trust that the manufacturers will stand behind their products?” 20 PIC Magazine • June 2015
With the ultimate goal being comfort and safety for workers and employers, Finlayson knows companies that buy their employees’ equipment need to ensure they are of a high standard. “When you are working in some of the most demanding conditions, you need to know that your clothing will perform as expected. Leaving the jobsite during the day to replace torn personal protective equipment is not an option for a lot of people. Companies need to trust that manufacturers and brands are using fabrics and materials that will last and protect all the time,” he states. Whether you’re on a budget, or just starting out in the industry and don’t know what to buy first, Finlayson shares what goes on your feet can get you to dance a jig on the way to work, and also on the way home. “I have never heard a complaint from someone who has purchased great boots that it was not worth the investment. One of our biggest retail partners, Mark’s, sells a line of Helly
Hansen Workwear boots that are drawing rave reviews. Mark’s is also known for their very strong line of Dakota products,” he adds. But that’s not all. Finlayson also recommends that you invest in some quality bottoms: shorts or pants, whichever you prefer are best suited to the job. “You are going to be wearing these every day and they will be subject to wear and tear, especially by our hardest-working customers. Buy the ones that you will not need to replace every few months or it will cost you more in the long run,” he explains. This summer, Finlayson’s go-to product is their Chelsea Construction Pant. Taking off faster than any other product they’ve launched in the last decade, and a hit in Europe for several years, this multi-purpose clothing item has everything you need in a work pant. “It has hanging pockets in the pants for nails, screws and other pieces, Cordura reinforced knees and cuffs, and a nice blend of
canada | U.s. | international cotton to ensure it is a little cooler in the summer. It works well for any tradesman - working inside or outside.” Keeping cool while working is an achievable goal as what you’re wearing moves sweat away from your body. “The body’s temperature drops when sweat stays in the fabric, causing a chilling sensation. You want layers that will move moisture away from the skin so it can evaporate. You don’t want employees to cool off too much, but you also don’t want to run the risk of heat stroke,” explains Finlayson. Working outdoors means you have to be ready – rain, sun, wind – you can never really know what to expect. To be completely geared up, Finlayson recommends: “Boots, moisturewicking baselayers (including socks, a t-shirt, and a hat), a midlayer that is UV protectant and an outer layer depending on the weather

PIC New Central Library Raises More Than Just Expectations
canadA | U.s. | international
By Melanie Franner
Calgary’s New Central Library will soon be a welcome addition to the East Village, helping to re-connect this vibrant new community with the downtown core. It will certainly stand as a landmark building – an unusual geometric oval shape with a soaring, four-storey atrium – but it will also stand as a testament to innovative design, engineering – and piling.
An unusual site The reason the New Central Library will be one of the city’s more prominent architectural feats lies with the fact that it is being built on a piece of land bisected by an existing LRT line. This necessitated the architects lift the ground plane up and over the LRT tracks and create a raised foundation in the process. No simple task. But fortunately, Calgary Municipal Land Corporation (CMLC) was able to tap into some well-honed experience. “CMLC hired us to do a study that showed 22 PIC Magazine • June 2015
it was possible to build over a live LRT track,” states Ian Washbrook, associate, Entuitive, the structural engineering firm on the project. “We had the unique experience of designing and building the Manhattan West platform at Penn Station in New York, the busiest commuter rail line in North America, on a site that was dissected by many active rail lines. Our solution for that project demonstrated that it was economically feasible to build over the existing LRT tracks on the Calgary site.” Next up was the architectural team, which was comprised of Snøhetta and DIALOG. “We viewed the site as a ‘probatunity’, which is a combination of problem and opportunity,” explains Rob Adamson, partner, DIALOG. “The geometry of the curving train tracks meant that the building was sort of separated in two. There was no budget in the project to re-align the tracks so we had to sit back and think of how we could leverage the situation to be an opportunity. We ended up designing
a curving, structural system to the building. The fact that we had to go up and over the LRT tracks enabled us to make an amazing outdoor public plaza where people in the community can congregate.” Building up and over the LRT tracks meant that the tracks had to be encapsulated – the first time in Calgary’s history that an active LRT line is being encapsulated to allow for above-grade development. The project will cover 135 metres of LRT track and is covered within the New Central Library’s total $245-million budget. The other twist in the project was that the LRT had to remain operational. “We had very limited opportunity to work with the LRT corridor shut down,” states Washbrook. “The window of time was between 2 a.m. and 4 a.m. each morning. That, and the very rare times when the tracks were shut down for regular maintenance, were the only incidents of the power being shut down.
canada | U.s. | international
During operational hours construction cannot take place within the right of way. Innovative construction solutions were needed to limit and mostly eliminate work within this zone.”
Piling particulars Entuitive started on the project in January 2014. The design encapsulation and construc-
tion documents were completed in August. The structural engineering firm did, however, begin sequential tendering in September to advance the pile work. The piling work started on the east side of the site. “Our solution to encapsulate the tunnel prior to building the library involved the use of very, very deep piles that ranged between 18 and 25-metres long and with diameters of four to six feet,” says Washbrook. “The piles were rock-socketed in 10 metres or more of bedrock. We then installed the grade beams and steel posts in the pre-formed wall panels before pouring the tunnel walls.” The pre-cast double-tee roof structure is scheduled for installation on top of the preformed walls in August 2015. The existing LRT communications and power lines on the north end of the east side of the site posed a bit of a challenge in the encapsulation process. “There was one area, in particular, where the communications and power lines were right in the way of our piles,” states Washbrook, who adds that the piles were spaced 10 to 12 metres
apart. “We didn’t want to increase the width of the tunnel in that particular area as it would increase costs significantly and increase the depth of the tunnel structure required, resulting in an architectural impact of the library. We had to build a temporary cantilevered frame to support the rerouting of permanent communication and power lines before

the new permanent piles could be advanced through the abandoned existing communication and power lines. This took some planning and sequencing. There was a four-month period where no piling took place while this rerouting was taking place.” Eighteen piles were driven in the southern end of the east side of the encapsulation project in September 2014. The remaining three piles on the east side went in after the rerouting of the communications lines.
Work in progress “This project is very challenging,” states Rodrigo Fragachan, project manager, Bauer Foundations Canada Inc., the company charged with doing the piling for the LRT encapsulation component of the project. “The piling work occurred right beside the highvoltage LRT lines so it meant for very, very tight conditions. We used a Bauer BG28 rig, which barely fit in some areas.” Fragachan adds that the tightest corner on the site was about eight metres wide. The encapsulation piling project was divided into two phases. A temporary working platform had to be installed in order to ensure that the rig was stable and would not affect the active LRT. “The majority of piles used tremmie con24 PIC Magazine • June 2015
canadA | U.s. | international
crete methods due to the presence of groundwater in the pile bore,” says Fragachan. “We installed mesh and barricades as additional safety measures to ensure that nothing got on the tracks. All the groundwater had to be pumped, treated and then disposed of.” According to Fragachan, the company had an average crew size of between five and seven on site during the piling work on the east side. “One of the biggest challenges we had was the use square dowel cage inside the centre of the pile’s reinforcement cage in order to accommodate the grade beams,” he says. “The dowels had to be installed in a particular orientation and extra caution was exercised while extracting the casing in order to reduce the rotation of the cage.” Fragachan and his team completed the piling work on the west side in May of this year. They then had to disassemble the rig and move it to the east side before re-assembling it for work to begin anew. This alone will take three days.
West side story The piling rig was moved to the west side of the site in April 2015. This second phase of the encapsulation piling will involve 20 piles in total. Due to the tracks bisecting the site, the piling rig needs to demobilize and remobilize
as if the two sites are on opposite sides of town. The rig cannot drive overtop of the LRT tracks. “The work on the west side will involve several large diameter piles,” states Washbrook, who adds that the larger diameter piles will range between five and six feet. “The larger diameters are needed here because some of the library columns share the encapsulation piles. There are four instances where we have four very large loads that will require large transfer pilecaps measuring more than 14 feet deep consisting of two, five-foot diameter piles.” The library itself will require approximately 90 piles measuring between four and five feet in diameter. Washbrook anticipates that mobilization for the library work will begin this summer.
A library like no other The New Central Library is scheduled to open in 2018. When finished, it will have been several years in the making and will have drawn upon the expertise of almost all involved in the project. But it will be a bold and striking embodiment of being able to accomplish the unthinkable – of bringing together two separate physical sites to create a unified whole and, in so doing, connecting two disparate communities to create a stronger city core. n

Sept-Iles gets a multi-user wharf By Colleen Biondi
The tiny town of Sept-Iles, Quebec, is a shipping icon and the busiest port in Canada next to Vancouver and Saint John. Specifically, the community has transported billions of metric tonnes (MT) of iron ore, from the Labrador Trough, to destinations like China, since mining began in the area. That history, although impressive, may be a thing of the past. Sept-Iles now has bragging rights to a brand-new, 450-metre-long, multi-user wharf which will fundamentally change the look of the industry and its impact on the economy. The $220-million project – which began in the fall of 2012 and is just now operational – makes Sept-Iles the largest port in North America and poised to double its annual exporting capacity to 50 MT. The cost of the project was shared by the federal government (25 per cent), the Port Authority of Sept-Iles (25 per cent), and five iron ore mining companies (50 per cent). The new dock infrastructure allows two Chinamax freighters (each freighter can hold 350,000 MT of product) to come right to the dock for loading; this replaces the unwieldy process of loading up on small ships at the dock and then going out into the bay to trans load onto big tankers. It is, quite simply, a deal 26 PIC Magazine • June 2015
changer for the community – Sept-Iles will be a more competitive global player in the iron ore export business, competing neck and neck with the likes of giants like Brazil and Australia. Three years ago, Bermingham Foundation Solutions of Hamilton was asked by the project’s general contractor, Pomereau, to bid on the foundational elements required for the project. It was appealing and a good fit says Greg Stokkermans, professional engineer and project manager for Bermingham Foundation Solutions. After all, the company was an expert in marine work, having completed dozens of Canadian projects. They got the nod that fall and began mobilizing in November 2012. The foundation components of the job – installing piles and drilling caissons – took one full year (the superstructure took a year longer). The shiploaders have recently arrived from China after a 43-day, 10,275 nautical-mile trip through the Panama Canal, along with an elevator, a tripper car and 27 conveyor galleries needed for this world-class structure to fully function. Providing the foundation for a project of this magnitude and sophistication had its share of challenges adds Stokkermans.
The year-round construction schedule meant working in extremely cold conditions and battling both gusty winds and ice during the wintertime. During that timeframe, the order of the day included heating equipment, breaking ice, providing thermal clothing for employees, and mitigating health and safety concerns with watch, exit, rescue and buddy programs. “You are on the Gulf and exposed to the Atlantic. It is very windy and you are working with very large booms. Ambient temperatures can be as low as minus 30 C. It is tricky,” he explains. Each of the 130 super-large piles, which measured 190 feet long and weighed 65 tonnes each, used on the project were installed in one piece, requiring a complex and speciallydesigned infrastructure of hoists, cranes, drill and lead systems. At Bermingham, engineers like Stokkermans’ design products like these using the latest 3D modelling and finite-element analysis software. They also use field instrumentation and laboratory experiments (measuring strain, pressure, temperature, and load) to perfect each tool’s usage. Advanced systems, like these, increase the productivity of pile driving operations by minimizing crane movements and decreasing the amount of time needed for the pile to be under the hammer and to be spotted (it is estimated that using such systems can increase productivity from an industry standard of 50 per cent to 75 per cent). But safety is the number one benefit. Care is taken not to exceed the limits of the crane, but the most critical safety bonus is the smaller work crew needed to drive a pile. Since piles are placed with the aid of the hydraulic spotter and lead, only a crane operator and front end man are needed to carry out the task. In addition, once at the bedrock, piles were drilled four metres into six-foot-diameter rock sockets to ensure safe distribution of the load. An elaborate false work system was also constructed in advance of the drilling to ensure
canada | U.s. | international
the piles were on location and supported. Five months after the piles were concreted, the false work was safely removed. Finally, there were the minke whales. It was mating season for the popular mammals between May 1 and July 15 and the noise and vibrations associated with the drilling were simply too dangerous to the animals and their procreating activities. The Department of Fisheries and Oceans originally asked the crew to take special care and to monitor their actions and their proximity of the whale pods. But eventually, they directed the crew to cease operations during that time. Bermingham proposed an alternative. They created a “bubble curtain” which used air bubbles to absorb the noise of the project and agreed to certain work methodologies which contained mitigation measures. For example, they partnered with a Halifax research firm to develop a monitoring program to track the exact sound the work was generating. They also created a special vision tool so they could see and accommodate the whales while working at night. The end result was successful. The project crew worked through the vulnerable period; the noise and disturbance to the animals was minimal and within authority guidelines. There were even personal challenges. Stokkermans, his wife and small baby relocated to Sept-Iles for the duration of the project. But even that was opportunistic -- the engineer is now quasi-bilingual and has developed an appreciation for the positive dynamics of smalltown living.

A better solution for solar farm drilling By David Wolfe and Craig Berninger
H.B. White drills postholes using a Soilmec SM-16 GT rig in the background. In the foreground, sewer pipes have been placed in the holes to prevent cave-ins.
The demand for utility-scale solar power grid systems, or solar farms, has skyrocketed in both the United States and Canada in recent years. This growth is in part due to government subsidies and tax credits such as the Feed-In Tariff (FIT) Program run by the Ontario Power Authority to promote the use of renewable energy. As the solar farm industry has grown, so have regulations for their installation. For instance, frost protection is now required to reduce the possibility that the foundational posts will move due to frost heave

– an upward swelling of the soil from ice growth during freezing temperatures. These stricter installation requirements have put increased demands on solar farm foundation installation. In addition, large solar farms are typically installed over hundreds of acres on a very tight schedule, requiring contractors to increase their productivity and cost effectiveness. As the industry evolves, so does the need for more reliable equipment to complete jobs faster. H.B. White Canada Corporation is a design-build contractor experienced in installing solar farms in Ontario, Canada in conjunction with the FIT program. H.B. White engineers, procures, constructs, and commissions complete solar power grid systems with the help of some subcontractors. When H.B. White constructed early solar farms, they used traditional methods and equipment. However, they quickly recognized that a new solution to solar farm installation was needed. They turned to Soilmec, using continuous flight augering (CFA) with Soilmec SM-16 GT rigs to get the jobs done right. At a typical solar farm, a rack is placed on four posts and then 36 solar panels are attached to each rack. The solar panels each weigh approximately 25 kilograms. The posts are installed at a depth adequate to provide the necessary uplift and lateral support, for instance to protect

against the uplift force due to wind blowing on the underside of the solar panels. The required post depth varies with the subsurface conditions, but posts are normally driven into the ground at a depth of about three metres.
Problems with traditional solar farm installation H.B. White has been working in the renewable energy sector for more than 10 years, starting with the installation of wind farms and more recently solar farms. In 2013, they installed a solar farm in Alfred, Ontario – a 10 MW site that included 5,500 posts, 1,500 racks, and 50,000 solar panels. They constructed this solar farm across 100 acres of land located in a low-lying bog during the early summer when the soil was dry, using traditional installation methods. Solar farm posts are normally installed with low-cost equipment. The postholes are drilled with an auger attached to a skidsteer, backhoe, or excavator, or they are simply pounded into the ground with a postdriving machine. When hard ground is encountered, an air-track drill machine is often used. During construction on the Alfred site, H.B. White used two skidsteers with 1.2-metre augers and multiple 0.6-metre extensions to drill holes with a 254 millimetre diameter and 2.4 metre depth. They then moved in hydraulic post drivers to pound in the posts the final 1.2 metres. When drilling with the skidsteer and extended auger, H.B. White had to track the machine forward as they lowered the boom to keep the hole straight. This was a serious challenge. On a daily basis, they broke auger extensions. And when they tried to drill fast, it resulted in non-vertical holes and led to a hole rejection rate as high as 25 per cent. Approximately 1,375 of the 5,500 posts needed adjustment to meet specifications. In 2014, they constructed another solar farm in Welland, Ontario, which was a similar size to their previous project in Alfred. Initially they moved forward with the traditional skidsteer method. However, this time they had the added challenge of winter weather and abrasive ground conditions, leading to a failure rate of 50 per cent when installing the first 500 posts. This was due to augers walking, metal breaking from the cold temperatures, and holes that weren’t straight. A change was needed to make their budget and schedule.
Operations are in full swing as H.B. White drills holes and installs smartposts with frost sleeves.
New solution for solar farm installation H.B. White began researching their options and Soilmec provided their solution: continuous flight augering using a Soilmec SM-16 GT rig. The choice was clear, once they did a detailed breakdown of the cost of their current installation method compared to the cost of renting the Soilmec SM-16 GT rig. For instance, they were previously drilling postholes with two skidsteers, two operators, and four labourers. This work could be done more cheaply and reliably using one SM-16 GT rig, one operator, and two labourers.

H.B. White struggles through harsh winter storms during the Marsh Hill Solar Farm installation.
Once they began CFA drilling with a Soilmec SM-16 GT, H.B. White’s rejection rate reduced dramatically while productivity increased. Using two skidsteers with augers, they were drilling approximately 50 holes per day with a 25 per cent rejection rate per machine. The Soilmec SM-16 rig allowed them to drill 100 holes per day with a 10 per cent rejection rate, where rejections were largely due to in line measurement errors or augers hitting rocks. The remaining 5,000 posts at Welland were installed using one SM-16 GT rig in three months, allowing them to complete the job on time and within budget.
Moving forward with a new solution H.B. White has moved forward with solar farm installation projects using Soilmec SM-16 GT rigs to drill all their postholes. Their latest solar farm project, the Marsh Hill Solar Farm, is located in Uxbridge, Ontario between Marsh Hill Road and Highway 12. It was H.B. White’s largest solar farm installation yet – 7,000 posts, 1,750 racks, and 62,000 solar panels installed over a 90-acre site. The solar farm is capable of producing 18 MW of power. They tackled the drilling using three Soilmec SM-16 GT rigs, which were equipped with augers that were 305 millimetres in diameter and 5.3 metres long. A fourth SM-16 GT rig was onsite as a backup. The drilled holes had a 280 millimetre diameter and 3.8 to three metre depth. The Soilmec drill rigs performed well, averaging over 60 holes per rig per day despite harsh winter conditions. A subcontractor was used for two days, but they were only able to complete 30 holes per day using an air-track drill machine with auger. The subsurface conditions at the Marsh Hill Solar Farm were difficult, consisting of about 2.4 metres of sticky clay on the top, 2.5 metres of dry creek bed with small cobbles mixed with clay and sand in the middle, and sticky clay beneath. Soil cave-ins were a major issue. However, H.B. White developed a strategy to avoid cave-ins. Once the SM-16 GT rig drilled a posthole, an ez spotter attachment on a skidsteer was used to temporarily place a sewer pipe into the hole to keep it open. This allowed them to drill about 100 holes ahead, followed by a crew that installed the posts. Later, the sewer pipe was removed with an excavator, a frost sleeve was placed by hand, and finally the smartpost for the solar panels was inserted with the excavator. The frost sleeve was a 273 millimetre diameter and 1.5 metre deep PVC pipe that was permanently installed down to the frost depth, in order to protect against smartpost movement due to frost heave. The smartpost was a rectangular, galvanized steel post with 32 PIC Magazine • June 2015
pre-drilled holes, which was named “smart” because the corresponding solar panel rack could be easily bolted onto it later. The smartposts were installed at a depth of 1.8 metres above grade, so they ranged in length from 4.6 metres to 5.3 metres. Once the posts were placed, a skidsteer with a concrete bucket was used to fill the PCV frost sleeves with concrete.
Overcoming challenges H.B. White faced many challenges during the Marsh Hill Solar Farm C construction. Their first challenge was to perform major site grading. They had to M provide fill up to 2.5 metres deep in areas throughout the site, adding a Y total fill of 52,045 cubic meters for the project. They also had to cut up CM to two metres deep in many areas with a total excavation of 50,985 cubic MY metres. And all of this had to be done in the first three weeks. The Marsh Hill installation was also a winter build with temperatures CY as low as -30 C. The concrete plant froze up twice. The cave-in protecting CMY sewer pipes were fragile at these frigid temperatures, requiring twice as K many sewer pipes to be used due to breakage. And H.B. White had to leave the equipment running overnight to prevent equipment damage and to avoid having to wrap blankets around the equipment to warm the hydraulics and fuel systems so the machines would start. They also faced subsurface and environmental difficulties. For instance, a large portion of the site carried a lot of water that caused soft, unstable ground. When building roads or trenching in this area, extra steps were needed to de-water. The water also caused problems when drilling, since the holes didn’t stay open for long and filled with water. Despite these issues, H.B. White was able to complete the project on time and within budget. This included drilling approximately 84,000 linear feet, pouring 2,380 cubic meters of concrete, and installing 7,000 posts, 1,750 racks, and 62,000 solar panels. This major solar farm was built on a tight schedule. The first hole was drilled in late November and the last hole in the first week of February, despite the winter storms and holidays. The entire solar farm was completed and energized on March 31, 2015. H.B. White is currently commissioning the site, which will take on a full commercial production load at the end of April.

Dignified end in sight for Sir Ambrose Shea Lift Bridge By Melanie Franner Lift Bridge is raised, on average, 2,500 times each year. It comes as no surprise then that the provincial government’s Department of Transportation and Works was forced in 2011 to tender the construction of a new lift bridge that would replace the aging structure. A $40.6-million contract was eventually awarded in March 2013 to HJ O’Connell Construction Limited, a joint venture between a division of Bird Construction Inc. and Vancouver Pile Driving Ltd.
It’s been more than half a century since the Sir Ambrose Shea Lift Bridge officially opened, connecting the Newfoundland and Labrador communities of Placentia and Jerseyside. The bridge was designed to span the “Placentia Gut”, a channel of water with tides that change direction every eight and a half hours. The tides themselves can attain speeds of up to nine knots. 36 PIC Magazine • June 2015
Using an unusual design for its time, the Sir Ambrose Shea Lift Bridge consists of two approach spans and one centre vertical lift span. Each measures 30 metres in length. The centre vertical span – which can be raised from a clearance of three metres to a height of 21 metres in one and a half minutes – weighs 100 tonnes. The centre span of the Sir Ambrose Shea
The government contract consists of replacing the aging Sir Ambrose Shea Lift Bridge with a new lift bridge in Placentia directly adjacent to the existing one, as well as realigning the adjacent roadway Route 100 and removing the old bridge once the new one is operational. Also included is the building and equipping of a control house for the bridge’s significant mechanical and electrical components. The project is expected to take three years to finish, with an anticipated January 2016 completion date. The new bridge was designed by Parsons (formerly Delcan), an engineering, construction, technical, and management-services firm. “The bridge is located in a very harsh environment, so the reliability of its operations is a high priority,” states Joanne McCall, division manager, Parsons. “Recognizing that simple and conventional operating systems bring the highest degree of reliability and minimize maintenance, we determined that these conventional systems, both mechanical and electrical, should form the basis of the bridge design as much as practical. Special care was taken to select members, details and systems that are long lasting and enhance the durability of the structure. Details include closed structural sections, enclosure of mechanical machinery and components, and minimizing exposure to the elements.”

Discerning details The new lift bridge requires the building of two 58-metre long temporary trestles, with 600-millimetre pipe piles, and a deck, to enable the placement of a 150-tonne crawler crane. The crane is used to construct the two new central piers deep in Placentia Bay. “Each pier required that we build an Lshaped work trestle and a cofferdam out to each of the two piers,” states Clancy Lannon, project manager, Vancouver Pile Driving. According to Lannon, each of the two piers required 136 pipe piles of 325 millimetre diameter. Thirty additional pipe piles of the same size were required for each of the two abutments. “The soil on the site was pretty complex. The Newfoundland and Labrador Department of Transportation and Works had boreholes drilled to 70 metres depth and found that the soil got looser with depth. Therefore, we had to do extensive PDA testing of the piles,” says Lannon, who adds that the testing was done by Ottawa-based Urkkada Technology Ltd. “We initially went in expecting to have end-bearing piles but we ended up with most of the load being borne by the friction between the shafts of the piles and the surrounding soil.” In total, the new bridge will use: 9,920 metres of pipe piling; 2,200 metres of sheet pile (for the cofferdams); 4,100 cubic metres of concrete; and 1,000 tonnes of structural steel. “Putting in the tremie concrete proved to be a bit of a challenge because of all the piles needed for the piers,” says Lannon. Another challenge was the strong current. “We had
limited times to do certain work. For example, the sheet piles could be cut off primarily during the low tide. We built a small platform and shield that would deflect the tide a bit to get us more time. We ended up with having three hours during low tide and only an hour during high tide.” The company used Gander-based Central Diving Ltd. for the underwater work. “It took 11 days for the divers to cut off the steel piles on the south pier and it will probably take another 10 days to do the ones on the north pier,” states Lannon, who adds that the company is just finishing the concrete on the north pier. After that, the structural steel can be erected and then the mechanical components installed. “The next tricky bit will probably be the installation of the left span, which will take place this summer. Sectional barges will be needed to float in place so that the span can be lifted by cranes. Securing the barges is going to be tricky with that current.” According to Lannon, the new bridge is located approximately 22 metres from the existing one. “It more or less uses the same construction concept as the old one, just different materials,” he explains, noting that there were no piles used on Sir Ambrose Shea Lift Bridge. “The new superstructure will also be tubular instead of angular like the old one, which is primarily for aesthetics and maintenance.” Vancouver Pile Driving was onsite for 18 months to complete the waterworks portion of this project.
In with the new Sir Ambrose Shea Lift Bridge has remained and will continue to remain operational during the construction of its successor, aside from brief lane closures. Its 50-year life span, however, has come and gone. Although the bridge has recently been repaired to enable its use until 2016, the community has already shifted its focus to the new lift bridge nearing completion. “The new Placentia lift bridge is a lasting and very necessary infrastructure investment which will benefit the people of Placentia and surrounding communities for many years to come,” stated the Honourable Paul Davis, minister of Transportation and Works when announcing the awarding of the contract to HJ O’Connell Construction. The Honourable Felix Collins, minister of Intergovernmental and Aboriginal Affairs, and MHA for Placentia, echoed his sentiments: “This is a major development and will ensure the long-term social and economic viability of the Placentia region.” The federal government has contributed $8-million toward the $40.6-million project. “It’s been a really interesting project,” concludes Lannon. “It’s a complex one in that it has some unusual challenges, such as the tides, strong currents and high winds, not to mention the soil itself. But the end result will be a new bridge for the community – one that will have a lifespan of another 50 years or so.” n Piling Industry Canada • June 2015 37
PIC A Simple Strategy

Great rigs bring the customers in; great service keeps them coming back
Xcel’s TR150 logged 4,000 machine hours over three years with zero down time. Here they are working on one of the 1,000 utility foundations completed during this time.
When Bay Shore Systems first introduced the LoDril® back in 1991, there were few, if any, low profile drilling rigs on the market that could satisfy the needs of a demanding drilling company. The market was hungry for a versatile, reliable, and powerful drill rig that could get underneath bridges or power lines, inside buildings, or over obstacles and still drill shafts in the depths and diameters needed. And they wanted productivity. That meant a rig needed to maintain powerful torque at drilling speeds of 30 to 60 rpm. Fast-forward nearly 25 years. The LoDril® tapped into this market and even the most biased observers have to conclude that it has been a resounding success. With nearly 600 rigs sold and more than 98 per cent of that number still working, there is little doubt that the LoDril® has had a lasting effect on the market. But the LoDril® is only one of several keys to success Bay Shore has implemented to earn its spot in the demanding drill rig market. “Early on we knew we could design and build a rig that would do the job,” explains 38 PIC Magazine • June 2015
Adam Minatre, vice-president of sales and son of company founder Herb Minatre. “But we knew that if we didn’t listen to our customers and provide them with exceptional service on an on-going basis, even the best rig in the world would not be enough to create long term customer relationships.”
busiest rigs in their fleet have come from Bay Shore,” says Minatre. “Of course we’re pleased with that. We want our customers to be successful in the drilling business and we want to create the equipment that helps them be successful. That’s why a big part of the drill rig business has to be committed to serving our customers. Downtime on a job means that our customer is not making money, we are more than a little obsessed with keeping our customers working.” The third part of the commitment to customers has to do with the service staff themselves. Bay Shore service technicians are experienced rig operators. They know Bay Shore equipment inside and out and can often troubleshoot a problem over the phone. They are skilled at listening, diagnosing, and communicating solutions to get a customer’s rig back in full operation. But, if not, they are prepared at a moment’s notice to travel to the customer’s job site and roll up their sleeves to solve the problem.
Passionate about customer service The drive for excellence in customer service has resulted in some innovative procedures that reach all the way from engineering and design, to service after the sale. First, whenever possible, Bay Shore uses common source parts in building their rigs. That means that customers can often find replacement parts quickly and easily at their local machinery dealer. Second, Bay Shore maintains an inventory of less accessible parts ready to ship at a moment’s notice. A recent customer service audit revealed that fully 95 per cent of all service issues are resolved in less than 24 hours. “Our customers tell us all the time that the

machine options, drilling depths and torque ratings means that our customers have what they need to cover the broadest range of drilling requirements.” The TR Series of rigs features mounting options from truck-based rigs, track-mounted rigs or excavator mounted units. Truck mounted rigs are PTO powered so the hydraulics for the drill are run off the main engine. This increases efficiency, reduces environmental impact and transportation and permitting costs. Truck rigs boast up to 70,000 ft-lbs (108 k-Nm) of torque and drill depths up to 80 feet (24 metres). Ergonomic controls make the truck rigs easy to operate and reduce operator fatigue that is common with archaic mechanical controls. Less fatigue means higher productivity

for rig owners and increased safety on the jobsite. “The truck rigs are increasingly popular with utility companies doing high voltage infrastructure work,” says Tippett. “They can
get in under high-voltage lines and still drill a deep enough hole to get the job done.” Larger, excavator mounted or track mounted rigs have torque ratings up to 200,000 ft-lbs and drill depths to 100 feet. Excavator mounted rigs are perfect for the on-slope drilling often required for transmission line foundations. Specifically, the TR150 mounted to an excavator has been a customer favourite for utility foundation work as a massive effort is underway to modernize transmission lines. A perfect example of Bay Shore rigs working profitably for customers can be found in Xcel Energy. “Xcel Energy used a TR150 for three years with zero downtime,” notes Minatre. “During that time they logged more than 4,000 machine hours, drilled 1,000 foundations, and poured 150,000 yards of concrete. All with a single TR150 providing the drilling work. That’s exactly the kind of performance we expect from every piece of equipment that leaves our facility.” If there is a lesson to be learned from the Bay Shore experience over the past 25 plus years, it is this: There is nothing more important than listening and responding to your customer. Do that simple thing and your customers will keep coming back for more. In the drilling business, as in any business, your customer’s success is also your success. n

The equipment-intensive project hinges on two German-manufactured RTG Rammtechnik GmbH pile drivers rented from APC Member Equipment Corporation of America (ECA), a prominent distributor of specialized foundation construction machinery for heavy commercial, civil, mining, and marine construction projects with East Coast and Canadian locations and a legacy dating back nearly 100 years. The RG 19 T and RG 21 T pile drivers with telescopic leaders fueled EIC’s high level of production. Maintenance of the equipment, championed by ECA’s Sales Engineer Chas Raysik and a highly-skilled service department, was also critical since downtime was unacceptable on this deadline-sensitive, momentum-driven operation. EIC Project Manager Derek Serpe speaks with a calm and collective demeanor, suggestive of EIC’s bold, performance-driven culture. When he talks of an “unmatched level of service,” his sincerity is genuine. It’s apparent that both contractor and distributor are aligned on the importance of maintaining the schedule. “We’ve had instances where it’s the middle of the day on Saturday and something is broken,” Serpe recalls “We called Chas and there was a mechanic out there on Sunday. By Monday at 7 a.m., we were back to work.” It’s apparent that this 10-year partnership remains intact based on personal service where the head of ECA’s

defining factor in punching through the heavy layer of clay beneath the beach.
Tight Working Space Pile Driving Power The sheer power of the RG 21 T pile driver can be felt as steel vibrates against steel high above. Sand particles rain down lightly and the beach flexes as the 45-foot-long steel pile seems to slide into sand with the ease of a candle pushed into a birthday cake. Dirk Himborg, RTG Rammtechnik’s sales director for North America, describes the operation over the staccato pounding of the high-frequency vibrator overhead. He makes a machine-gun-like noise to mimic the sound of 3,000 rounds of vibrations per minute administered by the RG 21 T. It starts with ensuring that the holes drilled in the sheet piles are symmetric so operator Rich Kaminski can properly hoist and set them in place with the RG 21 T. Once the hammer is properly positioned atop the pile, the vibrator ramps up to top speed and the descent begins. Because the sand is non-cohesive, the vibration essentially displaces the material in what he describes as a “fluid condition.”
Working in the Sand The geotechnical aspect of this project is intriguing for anyone that has tried to drive a beach umbrella into soft sand. The surface layer is fine beach sand, below which is a layer of black sand, clay, and an additional layer of fine sand. Himborg explains the science as the operation unfolds. “It’s all about friction,” he explains, indicating that the high water table is helpful. “When you come to a water-saturated area, it acts like a lubricant and facilitates the penetration process.” The steel sheets essentially displace the sand as they are driven. The RTG pile drivers feature an active push system, according to Himborg, which allows the machine to plow through dense materials such as clay. The sand on this project was no match for the RTG’s. While EIC occasionally encountered clay at the tip elevation, the pile drivers were met with little resistance. Drive time hovered between two and three minutes 95 per cent of the time. He describes the situation as “putting the brakes on the hammer” when the sheet breaks through the clay below and needs to be stopped by the rig. Serpe indicates that the power of the RTG’s was the
The worksite, framed by a towering dune and stockpiled steel sheets, is not much wider than a couple bowling alley lanes. Just above the dune, a curious neighbour watches the pile-driving operation from the upper deck of a multi-million-dollar beachfront home as the RG 21 T vibrates a sheet into the sand. “In this area, you can’t get any more of an easement or you’ll be in someone’s living room,” Serpe says with a laugh. The wall was designed to follow the easement between the shoreline and the dunes, while adhering to residential property line setbacks, and tying into the future beach fill project. This required close coordination with the USACE and the NJDEP.
Invisible Protection EIC will not only deliver protection to the barrier island of Mantoloking, but the finished project will restore the beach to its original appearance. This is the first phase of a $300-million USACE beach fill project that will build up dunes, a berm, and extend the beach by 200 feet between the Manasquan and Barnegat Inlets. When all is said and done, Mantoloking will return to the bucolic island atmosphere that residents have traditionally enjoyed. But it will

be stronger. This wall of steel will be a distant memory, disguised by dunes. “You’re never going to see this wall,” says Serpe as waves crash gently nearby, “and it’s the last line of defense, if God forbid, the big storm ever comes again.” It seems like a small price to pay. n

New pile driver delivers on all counts By Melanie Franner
When Roberval, Quebec-based Gilbert Products Inc. began working on a new pile driver prototype, it did so with its customers in mind. Two years later that prototype has become a reality and the company’s customers are using the new side-grip vibratory pile driver to both improve their existing business and expand into new business opportunities.
Money well invested “We’re very pleased with our return on investment,” states Serge Riel, foreman supervisor at Pieux Geodex Inc., a Montreal-based company involved in deep foundation work and marine structures. “Thanks to Gilbert, we now have a better line of equipment to service our customers.” That all-important line addition from Gilbert Products is the Grizzly MultiGrip, which was launched in fall 2014. “The Grizzly MultiGrip is unlike anything else on the market,” states Alex Gravel, direc44 PIC Magazine • June 2015
tor of sales and marketing, Gilbert Products, who adds a customer of theirs developed the initial prototype before approaching Gilbert Products for the fine tuning of the design, as well as the manufacturing and marketing of the product. “We are always receptive to new ideas. A lot of them come from our internal engineering department but some do come from our customers. We always value their input.”
It’s in the details The Grizzly MultiGrip combines power, versatility, and speed in a side-grip vibratory pile driver. At the heart of the innovative design is the attachment tool that can be used to increase excavator productivity and reduce operating costs. But the real excitement lies in the fact that this attachment tool – an exclusive lateral clamping device – provides for quick changes without having to go back to the shop. “The Grizzly MultiGrip is designed for ver-
satility,” states Gravel. “Users can work in Hbeam and sheet piling applications and then switch to round pile driving mode in five to seven minutes – while still on the jobsite. It increases productivity and saves a lot of time.” It also opens the doors to new opportunities. “We are now able to go from putting pipe in the ground to doing sheet piling in a little over five minutes,” states Riel. “In the past, we had to turn down a lot of the smaller jobs because it would cost us too much money to move the cranes and booms. By using an excavator with the Grizzly MultiGrip attached to it, we can put the bucket back on and start excavating right away.” Another advantage Riel and his team soon realized was the ability of the Grizzly MultiGrip to work in tight spaces. “Conventional cranes and suspended vibros need a lot of head room,” he says. “We had a few very tight places to work in, like under

PIC Get on Hercules’ Side
canadA | U.s. | international
The company’s side grips have been revolutionizing worksites since 1998
Hercules Machinery introduced the first side grip in the industry 17 years ago and since then has perfected the Movax® Sonic SideGrip®, placing more than 500 units at worksites throughout the U.S. and Canada. An excavator-mounted attachment, this vibratory pile driver features an articulating side grip with two unique side-gripping jaws and one bottom jaw that deliver unmatched dexterity when handling, driving or extracting nearly any style of piling. Designed to deliver the utmost efficiency, the Movax Sonic SideGrip can not only drive pile up to 50 feet, but it also reduces the amount of peripheral equipment needed, like cranes, loaders and manlifts. It uses an excavator’s hydraulics to safely and quickly pick up, unload, place, drive, and extract piling. With the most advanced auto-steering system available, the Movax Sonic SideGrip precisely drives pile at 3,000 vibrations per minute. Its superior maneuverability means the Movax Sonic SideGrip can expertly handle challenging worksites with low overhead or narrow passageways. “We use the Sonic SideGrip a lot in pits and in buildings where we don’t have the headroom clearance,” says Patrick Kirchner, vice48 PIC Magazine • June 2015
president of Force Construction. “It performs well for us every time.” Hercules has continued to enhance the design, development, and testing of the Movax Sonic SideGrip, resulting in a superior machine that far surpasses the performance of conventional vibratory drivers/excavators. “We apply our extensive experience and the knowledge of our engineering team to innovate and manufacture the very best product for our customers, effectively increasing their worksite performance and efficiency,” says Tom Dame, national sales manager at Hercules Machinery. “By continually perfecting the Sonic SideGrip, we’ve helped customers increase production rates and positively impacted their bottom line.” Additionally, Hercules Machinery backs its customers with comprehensive support and training, ensuring they get the most out of their machine.

Managing risk with Fugro Loadtest’s innovative solutions Fugro Loadtest is dedicated to advancing the deep foundation industry managing risk with O-Cell®, SoniCaliper™, and RIM-Cell® technologies to provide safe, efficient, and innovative foundation solutions worldwide.
O-Cell – design calibration The Osterberg Cell (O-Cell) is the premier foundation element static load testing method. No project is too big or too small to recognize economic benefit from use of the O-Cell. They have been successfully used to test a variety of foundation elements including drilled shafts, auger cast piles, barrettes, driven piles, and helical piles. To date, Loadtest has conducted thousands of successful O-Cell tests in over 60 countries. Loadtest is approaching a quarter century of foundation performance advancement as demonstrated by the increasing world record load test history, including the current 2013 Louisville, KY 72,600 kip record. This demonstrates the ability of the O-Cell to measure true geotechnical capacity allowing for designs to be pushed to more economic performance levels. Many ultra-high capacity foundations are designed today as a direct result of Loadtest’s ability to calibrate and verify foundation performance. The O-Cell’s ability to provide geotechnical failure in the foundation materials makes it the optimal risk management tool for establishing key design calibration information. Foundation design optimization seeks economy by maximizing the use of available materials strengths. This calibration approach requires the consideration of risk in quality construction and final product performance. The risk management approach to construction quality considers the question of construction influences and identifies construction issues to prevent.
SoniCaliper – construction risk management Managing drilled foundation element construction risk requires understanding how defects, which affect foundation performance, can occur in the manufacturing process. Excavation conditions prior to concrete placement influence foundation element quality. This di50 PIC Magazine • June 2015

rectly relates to the foundation’s ability to safely service the needed loads. Interpreting load test data from excavations with cross sectional area variations was the incentive for SoniCaliper development. As with many developments additional beneficial uses become apparent after implementation. SoniCaliper measures the excavation shape and determines the actual excavation volume as compared to theoretical plans volume, information which assures sufficient concrete delivery. This information allows for planning assuring proper tremie embedment, minimizing potential for cold joints or defects from tremie broaching. Physics dictate that a decrease in SoniCaliper return is directly related to presence of particulate in the slurry column; an indication of a need for rechecking the excavation slurry cleanliness parameters against specification requirements. Slurry cleanliness is of import as settling particulate can aggregate at the excavation tip reducing end bearing capacity and/or settle on the top of the concrete column, becoming deposited as defects causing reduced lateral capacity.
SoniCaliper measurement of excavation alignment is quality critical as reinforcement steel placement can drag side wall materials into the excavation also producing soft toes and defects in the lateral resistance area. The SoniCaliper is a cost-effective construction risk management tool for QA/QC of deep foundation elements such as drilled shafts, slurry walls (barrettes) and secant walls.
RIM-Cell – performance verification Reliability Improvement Method, or RIMCell, is the latest technology in drilled shaft load confirmation and performance QA/QC. The RIM-Cell provides proof-loading of production foundation elements confirming, as constructed, design performance. The RIMCell is designed with drilled shafts constructability in mind with its large open center to minimize shaft toe disturbance and concrete flow obstruction during placement. Lightweight and simple, the RIM-Cell attaches easily to the tip of the reinforcing cage. The use of grout as the pressurizing fluid restores pile integrity after verifying foundation

element performance. Applied as a two stage process; stage one, the grout, confined in the rim, applies pressure at the pile toe and along the pile shaft verifying performance; stage two, grouts the annulus crack created in the first stage restoring integrity. Proof of foundation element performance to 1.2-1.3 times the required code loading (design, service, or resistance) verifies the design and minimizes two of the most troubling sources of uncertainty: site variability and construction defects. Use RIM-Cell as a statistical tool to verify foundation element design performance matches the LRFD code logic. It simultaneously reduces uncertainty and improves reliability. Knowledgeable upfront application confirms economical optimized geotechnical design parameters via lower factors of safety for ASD or higher resistance factors for LRFD codes. A secondary risk management benefit from RIM-Cell verification is its action as a post-construction stressing device. Unlike traditional base-grouting, the RIM-Cell’s grout pressure confinement offers high static pressure and a known load in every soil condition. This post-construction stressing engages the shaft end bearing resistance, reduction of settlement, and consolidation of loose material at the shaft toe, producing a stiffer initial response. Additionally, it reverses direction of the initial skin friction response, pre-loading it also providing an initial stiffer load response. Fugro Loadtest’s O-Cell, SoniCaliper, and RIM-Cell technologies combine to provide opportunity for foundation optimization from the design and construction into service. This three-step risk management approach of design calibration, construction quality and verification together produces the most economical efficient foundation possible. n

and maintains the anchor pressure during the monitoring period. Gas pressure is obtained from a pressurized nitrogen bottle. Each anchor is attached to a vibrating wire sensor (or, optionally, to a DCDT or linear potentiometer sensor) and can be linked to adjacent anchors by means of Swagelok fittings that grip the interconnecting rods. These rods can be adjusted to various lengths using a hacksaw. Connecting rods may be made from fiberglass, stainless steel, or carbon graphite. Readout is accomplished by connecting cables from each sensor to the Geokon Model GK-404 or GK-405 Readouts. Switch panels or multiplexers (Geokon Model 8032) are available to rapidly switch through all the active sensors. In this way the deformation of the pile under loading can be measured between each pair of adjacent anchors, the deformations are converted to strains and then to stresses and then finally to the load that is felt by the pile at various depths.
