Piling Industry News

Recent developments in SPT Energy measurements Pile Dynamics recently released a redesigned system for SPT hammer calibration. Both the hardware of the SPT Analyzer and the software used for analysis and reporting of Standard Penetration Tests (SPT) energy measurements have been completely revamped.

Standard Penetration Tests are a widely used geotechnical investigation tool that involves drilling an exploratory boring into the soil, driving a sampler into the bore hole and recording, among other things, the number of hammer blows required for it to travel a certain penetration – the N value. The sampler is connected to the bottom of a drill rod, and may be driven by a variety of SPT hammers, each of which with a different efficiency. This variability may cause the same soil to behave very differently depending on the equipment used for the test. Project specifications therefore often require that N be normalized based on the energy transferred by the hammer to the sampler. Both the European Code EN ISO 22476-3 and the North American standard ASTM D4633 state that the only acceptable method of determining this energy is by force and velocity measurements. In the United States, State Departments of Transportation typically require that the equipment used to perform Standard Penetration Tests be periodically ‘’calibrated” in this fashion.

The SPT Analyzer system includes a main unit (pictured) that processes strain and acceleration measurements obtained during the test itself. The measurements are acquired by attaching a rod section specially instrumented with two strain gage bridges and two Pile Dynamics-brand accelerometers (collectively referred as sensors) to the SPT drill string. Once the hammer hits the drill string, the SPT Analyzer processes the strain and acceleration measurements, which respectively yield the force and velocity necessary for the calculation of transferred energy.

In the newest release of the SPT Analyzer, Smart Sensor technology allows the program to ‘’read” the rod instrumentation, so that sensor calibration and rod cross sectional area are input automatically to the SPT Analyzer. This simplifies the initial test setup considerably. This latest model of SPT Analyzer also responds to multi touch gestures and has numerous colour schemes available, making things like adjusting

time scale or display to better view data in the field much simpler than previously. A preprogrammed set of output quantities tailored to SPT calibration is presented to the user, who can, however, modify it to fit a particular project need. Data quality checks are available.

The SPT Software, which processes the force and velocity data obtained during the test, has been completely rewritten: it is now completely customizable, and creates detailed reports quickly and easily.

“It could reduce the time to produce a report by half, when compared with the previous version,” says Ryan Allin, senior engineer with Pile Dynamics.

The Pile Driving Analyzer® (PDA) system PDA-8G, also manufactured by Pile Dynamics, may also be used for SPT Energy calibration by adding on the SPT Software to the PDA software suite.

In addition to the SPT Analyzer and the PDA, Pile Dynamics produces several other quality assurance and quality control products for the deep foundations industry. The company is located in Cleveland, Ohio and has commercial representatives in all continents. For more information visit www.pile.com/pdi.

A BAUER BG 18 H Rotary Drilling Rig sits wedged between an earthen embankment, a shotcrete-covered bridge abutment, a maze of rusty steel trestles, and the underside of a historic railroad viaduct in Swarthmore, Pennsylvania on a glacial January morning. The rig, working in a low overhead configuration, was supported by a BAUER BG 20 H, both of which prime contractor Walsh Construction of Chicago rented from the nearby Aldan, Pennsylvania office of Equipment Corporation of America (ECA).

Rebuilding a historic viaduct This high-profile $89.9-million South­ eastern Pennsylvania Transportation Authority (SEPTA) project requires the complete replacement of the 925-foot-long, 100-foot-high Crum Creek Viaduct. The structure Walsh is replacing, built in 1895, underwent repairs in 1983, but was in dire need of replacement to safely carry SEPTA’s passengers on the Media/Elwyn commuter rail line. The original bridge on this site was a pre-Civil War era, five-span timber arch truss bridge on masonry piers.

It was owned by the Philadelphia, Baltimore & Washington Railroad (PW&B RR) and later acquired by the Pennsylvania Railroad.

Walsh began construction on the substructure in summer 2015 and is working aggressively toward an etched in stone deadline of summer 2017. Despite the variety of construction processes involved, drilling the foundations for new footings, piers, and abutments was the key to the project.

New DZ Profile The next generation in piling.

29� deeper, wider & lighter sheet piles.

No ordinary site conditions, no ordinary drilling rigs Walsh and ECA began discussing the project in March 2015 at The International Foundations Congress & Equipment Exposition (IFCEE). ECA’s Aldan Branch Manager Tim Dutton and Engineering Sales Manager Gordian Ulrich walked the site in April with Walsh Superintendent Richie Vance to determine which drilling rigs would work best on this challenging site.

It was ultimately determined that Walsh would rent the BG 18 H and BG 20 H Premium Line Drilling Rigs because they were light enough to navigate rough terrain with adequate hydraulic output to core through hard rock of up to 25,000 psi. The low headroom capability of the BG 18 H was determined to be optimal for drilling in work areas with height restrictions.

ECA delivered both drilling rigs in June 2015. The BG 20 H, part of the Aldan location’s existing rental fleet, worked on site through Christmas. ECA coordinated manufacturing and delivery of the BG 18 H with BAUER Maschinen and imported the rig from Schrobenhausen, Germany. Its unique ability to work in both low overhead and standard configuration kept the BG 18 H on site until February 2016. ECA brought in an operator from BAUER to assist with training, but all on-site service and reconfiguration of the BG 18 H was handled by its own technicians in Aldan.

These Premium Line rigs offer some additional benefits over BAUER’s Value Line that were ideally suited for the Crum Creek Viaduct project. The main difference between the two is that the Premium Line features a crowd cable system with a winch as opposed to the crowd cylinder system on the Value Line. The Premium Line rigs, as a result, deliver more crowd force. They also comply with the latest Tier 4 emission standards, and are heavier machines with greater hydraulic output.

The BAUER BG 18 H Rotary Drilling Rig works in low overhead configuration to install drilled shafts near the Crum Creek Viaduct west abutment with limited overhead clearance. Walsh rented the BG 18 H and BG 20 H from Equipment Corporation of America to install eight 20- to 58-foot-deep, 36-inchdiameter drilled shafts at each pier and 12 at each abutment.

Foundation work sets the pace Walsh is tasked with building a new viaduct beneath the original structure before demolition can commence. The keystone of the project is foundation work for the sub16 PIC Magazine • June 2016

structure, which includes two abutments and four sets of piers. Walsh used the BG 18 H and BG 20 H Drilling Rigs to install eight 20to 58-foot-deep, 36-inch-diameter drilled shafts at each pier and 12 at each abutment.

Vance indicated in January 2016 that drilling was a week and a half behind schedule primarily due to unexpectedly hard rock and environmental permitting delays, but he was confident that Walsh would be back on track shortly. Despite the unforeseen challenges, Vance was satisfied with the drilling production rate.

“Drilling is make or break,” he says, as a SEPTA railcar rattles across the viaduct behind him. “Depending on how that goes, it’s almost how the whole job goes.”

Soil conditions? It’s complicated Project Geologist Bill Bradfield of Schnabel Engineering’s West Chester, Pennsylvania office describes the Crum Creek site as “interesting.”

“We ran the full gamut of drilling conditions within the span of this bridge,” he says, noting that metamorphic rock in this region can be highly variable over short distances.

The site contained primarily Schist, but production was hampered when crews hit Amphibolite. This extremely hard metamorphic rock was prevalent near the western abutment and the Crum Creek channel.

Bradfield recalls watching production drastically improving from as little as two feet per day with an auger to a foot an hour using the BAUER roller bit core barrel, which is recognized as a respectable rate of production in hard rock. Walsh initially tried a cluster drill but had no luck keeping the tool straight. The switch to roller bit core barrels also quieted drilling chatter and reduced the strain on the drilling rigs.

Roller bit core barrel keeps production rolling Dutton confirms Bradfield’s observations, noting the production increase was mainly due to the switch from conventional tooling to the BAUER roller bit core barrel. “With conventional tools they were getting two to three feet per day,” he recalls, pointing to an extracted four-foot Amphibolite core.

Walsh purchased 10 tools from ECA, including primarily 36-inch augers, core barrels, drilling buckets, and roller bit core barrels. There were a few 42-inch tools for overburden areas where the rock was not immediately below the surface.

Site access, low overhead, steep slopes, and vibration monitoring The topography surrounding the viaduct

worked in standard configuration from late June through early October and was then reconfigured to low headroom.

Vance says the height restricted areas were more severe than expected because the viaduct elevations Walsh was initially given did not account for drilling nuances. He indicates that maneuvers such as putting the drilling rig in crowd force, or pulling up a full bucket can require up to eight inches of additional overhead space.

From Piles to Pucks The construction of Edmonton’s Rogers Place With just 30 National Hockey League (NHL) arenas in North America, the opportunity to build an NHL-worthy rink from the piles up is a rare and unique opportunity that few in the construction industry will have the chance to experience. Built in 1974, Edmonton, Alberta’s Rexall Place was one of the league’s oldest arenas and well past its prime.

So it’s with great anticipation that the city has been watching the creation of its new multiuse arena since spring 2014. With the finishing touches being added to Rogers Place, the future home of the NHL’s Edmonton Oilers, we take a look at the structure’s impressive construction below ground.

With a square footage of 819,200, a height of 43 metres, and an expected weight of over 8,000 tonnes, the structural elements of Rogers Place must be as sturdy as an NHL defenseman. Indeed, 700 piles were used in building the arena; typically cast-in-place concrete end bearing piles with belled ends, explains Jodi Tauber, the City of Edmonton’s communications officer for Rogers Place.

There were two nominal depths at which the piles are founded. One bearing level is at an approximate elevation of 657 metres; the second bearing level at approximately 645 metres. For reference, the nominal elevation of the arena’s below ground parkade is 663 22 PIC Magazine • June 2016

metres and the majority of the event level is at 667 metres.

Three full-scale pile load tests were done early in the design phase. “The intent of these tests was to obtain actual capacities of the soil at the proposed end bearing depths.

Two tests were done at elevation 645 metres, and one test was done at elevation 657 metres. The results of the load tests confirmed that the theoretical bearing capacity of the soil was correct at each bearing level. In addition, by conducting the pile load tests, we were able to increase the design material resistance factor for the soil from 0.4 to 0.6,” says Tauber.

This resulted in a 50 per cent increase in the design capacity of the end-bearing piles, which was critical for the piles on the project supporting the largest loads. This increased capacity also allowed the remaining piles to be smaller in size.

The self-weight of the structure, along with applicable live loads in the building are accounted for when determining the total factored load on the piles. The size and bearing depth of the piles are selected to resist the total factored dead and live loads on them.

“Although this building had a large number of piles, and some of the design loads were very large, in our opinion the design

of the building’s foundation system was relatively straight forward,” says Tauber. “Individual column loads were supported on individual piles; no pile groups were required.”

However, one interesting aspect of the building was that lateral loads on the steel superstructure above grade were transferred through the event level slab, which acted as a diaphragm, to discrete shear walls in the parkade. The loads in these shear walls were then resisted by supporting piles.

Above ground, the multi-use arena is piled high with seats waiting to be filled – 18,647 to be precise, including 9,000 seats in the lower bowl, 4,100 club seats, 56 suites, 24 mini-suites, and 1,116 loge seats around tables. The typical food and drink outlets, shops, and a restaurant will occupy space in the concourse to ensure Edmonton’s hockey fans have the sustenance to cheer on their home team. Rogers Place will also boast the largest, true high-definition scoreboard in any NHL arena, measuring 46 feet wide, 46 feet deep, and 36 feet high.

All of this comes with the hefty price tag of $483.5 million. The City of Edmonton is contributing $225 million, including $145 million from a community revitalization levy program and $80 million from parking revenues and re-allocation of a subsidy

to the old arena, says Tauber. The Edmonton Arena Corporate (wholly owned by the Katz Group) is contributing an additional $132.5 million, while the remainder of the cost will come from a ticket surcharge.

The entire process has taken over two years with completion finally coming to an end this summer. Set to open in September 2016, the public will have the chance to see the finished product at an open house on September 10, with other major events to follow, including a Keith Urban concert, and of course, the Edmonton Oilers’ first game of the 2016-17 hockey season.

After a lengthy construction, the longawaited opening of Rogers Place can’t come soon enough for the people of Edmonton.

Rogers Place will be a strong, formidable home for their Oilers, and an iconic sight on the Edmonton skyline that will stand tall for

Pacific Pile & Marine completes test piling at Port of Seattle

By Michael Schwartz Terminal 5 at the Port of Seattle is now closed as the result of a multi-year redesign. During this period of non-activity, Terminal 5 will be modernized with an expected completion of 2019. The purpose of the modernization is to seismically upgrade the terminal and increase overall capacity to attract larger vessels to the region and grow annual seaport container volume to more than 3.5 million Twenty Foot Equivalent Unit, or TEU. Currently, the Port can offload cargo ships of up to 6,000 TEU. After the modernization efforts, that capacity will increase to 18,000 TEU. The terminal’s redevelopment reflects the need for heavier cranes and deeper drafts to accommodate trans-Pacific mega-ships. Piling work for the test pile is valued at $2.37 million, but may ultimately save millions on the future project with an estimated budget of $230 million.

The piling contractor at Terminal 5 is Pacific Pile & Marine (PPM). Nikolay Kuzmanov, one of PPM’s project engineers, set 28 PIC Magazine • June 2016

As Nikolay Kuzmanov points out, “The Port of Seattle has chosen to use driven piles because they are ideally suited for marine construction applications, notably in that they are environmentally friendly, with no spoils for removal and without the need for disposal of potentially hazardous materials.

Nor is there any requirement for special casing, or concrete, and curing time. After driving, the construction can proceed immediately. Large-diameter driven piles are best to resist seismic forces in highly seismic regions as the greater Seattle area is.”

The test pile programme consisted of six 600 millimetre concrete octagonal in-water piles, as well as eight 700 millimetre and one 600 millimetre steel upland piles. PPM remains active in the local market and looks forward to future opportunities to assist the Port in its pursuit of improving aging infrastructure to be increasingly competitive in the global market-place. Meanwhile, its test piling project is a good step in the right di-

Challenging the Status Quo LCI-Canada showcases lean design and construction

By Melanie Franner Canada’s piling industry may soon be changing the way it approaches a project thanks to the creation of the Lean Construction Institute Canada (LCI-Canada). The not-for-profit organization officially began in June 2015, and has already won over many in the construction industry with its focus on adding value and eliminating waste in design and construction projects – not to mention saving money in the process.

“Our lean journey actually began in September 2008 in Seattle at a meeting with LCI in the U.S. when a commitment was made to establish a Canadian entity,” states Ken Smith, council member, LCI-Canada. “It’s taken a long time to gain momentum and build interest but we’re well on our way today.”

To help get LCI-Canada off the ground, the organization turned to the Canadian Construction Association (CCA). The CCA offers both a national reach and an established non-profit industry organization – two factors that have been instrumental in helping launch LCI-Canada. This allows LCI-Canada volunteers to focus on promoting “Lean Thinking” in the design and construction industry while operating as a special committee under CCA’s umbrella organization, with access to administrative support and a non-profit entity.

Building better Lean methodology has been around since the 1990s, with LCICanada harkening back to the “Toyota Way” manufacturing process.

It’s all about collaboration and working together to create better value through the elimination of waste.

“The time for lean methodology in Canada is long overdue,” states Kathleen Lausman, council co-chair, LCI-Canada. “Quite frankly, the Canadian construction industry has been going through years of frustration, not just from the owners having their projects take longer but also with the higher costs and general discontent around almost every project. No one is having fun anymore. It’s become a legal battlefield.

Everyone is determined that there is a better way – and that better way needs to start now.”

According to Lausman, the construction industry is unique in that there has been no increase in productivity over the last 20 years.

“Every other industry has made two to three per cent improvements per year,” she says, adding research on lean design and construction has proven that it delivers results.

Lausman cites data from McGraw Hill Construction 2013 in which the use of lean principles, methodologies, and tools resulted in improved safety, greater customer satisfaction, higher quality construction, reduced project schedules, greater productivity, and greater profitability.

34 PIC Magazine • June 2016

“Lean design and construction isn’t all about reducing costs,” states Smith. “It’s about improving quality, adding value, and eliminating waste. Project cost is reduced as a result of the process, not as a goal.”

Lean design and construction identifies a minimum of eight waste streams (transport, inventory, motion, waiting, over production, over processing, defects and skills), in construction projects.

“There is about 50 per cent of waste in every construction project,” adds Smith. “Approximately 25 per cent of that is unavoidable. That means that 25 per cent – or one quarter – is avoidable.”

Piling proficiency Lean design and construction is a project-delivery method relevant to all sectors of the construction industry – from the owners to the architects to the contractors to the trades and supply chains. It is also of prime importance to the piling industry. One simple lean fundamental is continuous improvement. Everyone benefits from that.

Lean is about breaking down traditional industry silos to gain knowledge and expertise from the right person at the right time.

“Some of the biggest risks in construction are around foundation systems,” explains Lausman. “If we don’t have insight from that particular trade or if we don’t have access to their knowledge and expertise, we’re going to end up with a lot of waste. Piling is a critical part of the project in that so much more value can be added by having the piling people participate in the lean journey. Bringing the piling contractor to the design table for difficult or variable soils conditions brings the right person at the right time to share experience and expertise.”

Smith cites the example of a recent project in Regina where the knowledge of a local piling contractor ended up improving quality, constructability, design simplification, reducing installation time, and, as a result of the innovation, reducing costs that would not have been available without the piling trade input.

“We engaged the entire project team on the project – the structural engineers, the piling trade partner and the soil consultant – to talk about the project even while the soil conditions were still being investigated,” he says. “The piling trade partner suggested a piling rig not locally available that had a greater depth capability. That enabled the use of piles with deeper drilling capability and smaller diameter sizes, reaching greater bearing capacities at depth, resulting in a simpler and more economical foundation installation. The greater bearing capacities were confirmed by deep-test drilling once the deeper piling rig was known to the project team. We couldn’t have done it without having everyone at the table working together, adding the right person with additional expertise and experience at the right time.”

New paradigm Although the benefits of lean design and construction have been proven over and over again, the new way of thinking is not without some challenges.

“I think cultural change is probably at the core of slowing its adoption,” says Lausman. “I think that the mindset is still very much a competitive one. The frustration that has grown in the industry among all parties has led to an adversarial position – and to dwindling profits. It’s the perfect time for change.”

And LCI-Canada is poised to nurture that change with its mandate to create awareness of lean design and construction, to offer education and training, and to share knowledge among all sectors of the industry.

“I think there is a historic lack of trust in the construction industry,” says Smith. “Lean design and construction is a cultural and transformational change. You can’t just tweak the way we do our business to improve quality to the customer, improve schedules and as a result of the process reduce costs. You have to challenge the status quo. You have to turn things inside out and upside down. It’s all about collaboration and changing the way you work together.”

The good news, according to Lausman, is that the construction industry has already recognized the fact that dramatic change is nec-

essary in order to grow the industry and increase productivity and profitability. The only question, it would seem, is the direction of the path to get there.

“My experience has shown that construction contractors tend to be early adopters,” concludes Lausman. “Most designers and owners tend to be more hesitant. But most construction associations have already begun outreach programs across the different sectors. It may not necessarily be lean design and construction but they at least recognize the need for change and the benefits of a team approach. The fact is that some associations are already working on getting their members to work together with owners and designers to facilitate change and improve the industry. That’s definitely a step in the right direction.” l

Smith cites another Saskatchewan example of lean design and construction in the 87-acute care Cypress Regional Hospital in Swift Current. The local piling expert brought onboard was so familiar with the variable soil conditions that one of the first questions he asked was whether the new hospital was going to be located on the north or south side of the street. That type of knowledge proved invaluable on the project.

“That piling trade partner suggested bringing in the Continuous Flight piling auger that was first used in the Edmonton area,” says Smith. “This European technology was new to the Canadian market and had never been used in Saskatchewan.”

The early conversations between the piling trade partner and the project team have since made the use this type of piling a lot more common in the Saskatchewan market.

“We achieved $1 million in savings on that project just by innovating and collaborating with the piling trade partner through lean design and construction,” adds Smith.

Who’s at Fault?

Collisions and traffic infractions on the job

By Lea Currie Driving in general is risky business, but with the road conditions sometimes associated with construction and job sites, your employees – and consequently your company – face even more hazards each and every day crews are out on the road. There are a host of potential risks, from accidents due to poor visibility and potentially deadly collisions with passenger vehicles, to regular driving concerns, such as speeding tickets and red-light cameras. However, the question over who exactly holds that risk – financially and legally – can be confusing, making a difficult situation worse.

While companies naturally want to ensure the safety of their employees on the job, they must also protect their own interests. Benjamin R. Hecht, managing partner at Pitblado LLP in Winnipeg, Manitoba, who specializes in labour and employment law, sheds some light on where exactly liability falls.

offences incurred while operating a company vehicle.

First off, rest assured as companies are generally not liable for traffic offences their employees may incur on the job.

When it comes to a collision, “for insurance purposes, or charges under The Highway Traffic Act or Criminal Code, in most instances, the driver is the one ‘at fault’ (if the driver is in fact determined at fault by the insurer),” says Hecht. All accidents attach to the driver, not the company, as corporations, of course, can’t actually drive a vehicle.

Employers can breathe another sigh of relief as the same rules generally apply to speeding tickets or other traffic infractions, such as distracted driving. “Traffic offences normally attach to the driver of

the penalty or offence is the driver’s conduct, not the company’s,” says Hecht.

However, the introduction of red-light cameras has presented new issues for employers. Typically, a red-light camera ticket for speeding or running a red light would be issued to the registered owner of the vehicle, who is liable regardless of who was driving. That means that in a situation where an employee is driving a company vehicle, whether it’s a passenger car or a truck, the employer is often the one stuck holding the bill.

To protect itself, Hecht recommends that the company transfer the legal responsibility to the driver through a written agreement or employment contract, which outlines the driver’s responsibility for any “In general, a signed employment contract is the best protection,” says Hecht. “If the employer chooses not to use an employment contract, a policy can be effective, provided it is: in writing; distributed to all employees; consistently applied to all employees; clear in its terms.

And it is recommended that there be proof that the employee received the policy and agreed to be bound by its terms.”

With many vehicles or pieces of equipment on the road, numerous employees and shift work hours, employers must plan ahead so they can determine exactly who was driving at the time of the ticket. On a regular basis, employers should fully document vehicle usage, including which employee is using which vehicle, the license plate number, and the time in and out.

“If the employer is unable to ascertain which particular employee was driving at the time of the ticket, then the employer is liable to pay the fine,” says Hecht.

Even knowing who the driver at fault is, collecting the fine from him or her can come with its own issues. Employers cannot simply deduct a fine from an employee’s paycheque. If an employee did not provide authorization, and an employer deducts the fine from the employee’s pay, the company could be in violation of employment legislation, Hecht explains. Therefore, provisions regarding deductions of fines should be addressed in the same written contract.

Civil actions The case of civil actions (a lawsuit by a private individual) comes with a completely different set of implications. Hecht explains that, “generally, an employer is vicariously liable for the negligent or tortious acts of an employee if the acts are committed in the course of employment.” Basically, this means that if an employee is in a collision that results in the death or injury of another person, both the employee and the employer can be held liable, and can be sued by the injured person or their family.

The basis of liability in this type of situation depends on: the existence of an employment relationship (i.e. an employer-employee relationship; independent contractor relationships may be different), whether the action occurred in the course of employment; and if the employee was performing a job duty, whether directly or indirectly required by a service contract.

As with many legal issues, there are many “ifs” and “buts.” For example, if an employee performs an act outside of the scope of employment, even with the permission of the employer, the liability strictly falls to the employee. But, if an employee performs an act within the scope of employment, but against the orders of the employer, and it results in the injury or death of another person, the employer is liable. However, if the employee strays so far that he or she is doing something not in the course of employment, but contrary to it, the employer is not liable.

While all the ins and outs are complicated, and there are many instances where a company could be found to be liable. Hecht explains that an employer has, “a right to seek indemnification from a negligent employee so long as the employer was not contributorily negligent.” In layman’s terms, that means an employer can protect themselves by ensuring that the employee takes responsibility for the cost of all possible future damage, loss, or injury. To break that down even further, to protect themselves, employers should have a written agreement, signed by employees, that says the company is not at fault for an employee’s actions on the job.

To protect your company, Hecht also recommends owners take a few additional steps: • ensure employees are properly licensed and trained • have ongoing education sessions/seminars • reward safe driving practises and behaviour Also, while there are no legal requirements that require employers to provide employees with such devices as Bluetooth technology or hands-free devices in a company vehicle, Hecht says it would be a best practise for an employer to help staff perform their duties safely, while bolstering the safety of the company itself.

And of course, when in doubt, owners and company executives are encouraged to seek the advice of a lawyer. As with any legal issue, there are many risks, and you should clearly understand all legal ramifications, preferably before there is an issue. l

One Hardhat at a Time Helmets to Hardhats Canada is helping to fill the labour gap

By Melanie Franner No matter what part of the construction or trades sector you’re in skilled labour currently and in the future is a concern. That’s part of the reason behind the formation of an innovative, not-for-profit organization called Helmets to Hardhats Canada (H2H).

Founded in Canada in 2011, H2H is designed to assist anyone who has served or is currently serving in the Regular or Reserve Force components of the Canadian Forces for a construction job in civilian life. The program offers the required apprenticeship training to achieve journeyperson status in any of the applicable 60 trades within the building and construction industry.

H2H is modelled after its U.S. counterpart, which was founded in 2003 by Canadian Joe Maloney, an Ontariobased boilermaker who was on assignGreg Matte (left) with one of the program’s successful veterans, carpenter apprentice Michele LoCiercero, LiUNA Local 183.

The program’s current funding is provided largely through various Canadian Building

“Mr. Maloney was tasked with getting the original program up and running in America,” says Greg Matte, executive director of H2H Canada. “He subsequently returned to Canada and, over the next three

to four years, went across the country and tried to generate interest among potential stakeholders. One of these stakeholders was the federal government, which provided a $150,000 grant from Veteran’s Affairs and

Trades Unions, along with corporate and private donations.

“Regardless of whether a vet has served in the military for three years or 35, that individual has learned a lot about himself, about how to listen to orders, to be innovative and how to work in in a team,” says Matte. “Vets typically come with tremendous skills that aren’t directly transferable to civilian life. But they have qualities and skills that make them very well suited for jobs within the construction industry. Our program is designed to help them attain

solution and rigorous quality control to successfully complete the project. As excavation progressed, the release of locked-in rock stresses and the presence of a shearband produced a global shift of the rock extending beyond the project site. The use of inclinometer and extensometer monitoring allowed RWH to observe the movement and verify the stability of the project site. RWH continually reviewed the monitoring results against the movements predicted through numerical modelling to confirm the shoring movements were within acceptable limits.

Further to this, at various excavation stages the monitoring data was inputted into the models to verify the design parameters and predict more representative future shoring movements. Classifying the type of movement seen in the North wall inclinometer (Figure 1) as a block movement was critical to verifying the stability of surrounding infrastructure. The monitoring and predictive modelling of the shoring allowed RWH to proactively assess and communicate the results of the movement to project stakeholders, reducing concerns regarding the stability of the shoring system, and helping keep the project on schedule.

In addition to monitoring, RWH uses empirical testing to verify design assumptions and drive innovation. Geotechnical design and construction is unique because it provides the opportunity to prove the adequacy of structural elements through testing. Elements can be proof tested or load tested to their ultimate limit state to verify the soil parameters used at the design stage.

RWH provides testing services on various shoring and foundation elements including strand and bar tieback anchors, micropiles, helical piers, and caissons through Osterberg Cell and Dynamic Load (PDA) testing.

Verification testing of geostructural elements is a critical step to building confidence in below-grade design and construction. RWH routinely applies limit states design to use less conservative soil parameters. This allows for an increased factored 44 PIC Magazine • June 2016

Piling Industry Canada • June 2016 45

Triple Threat Liebherr showcases three innovative products at Bauma 2016 At Bauma 2016, Liebherr emphasized its function as full-service provider for deep foundation applications with the trade fair premiere of its piling and drilling rig LRB 355 and its duty cycle crawler crane HS 8130 HD. Furthermore, the popular LB 36 rotary drilling rig was displayed in Munich with Kelly drilling equipment. All three deep foundation machines have already successfully proven their efficiency on jobsites throughout the world.

For repeated work cycles in deep foundation applications fuel efficiency is of particular importance. As an option, Liebherr offers its innovative automatic engine stop function. Thanks to this system the Liebherr deep foundation machines automatically cut off the power supply during longer work interruptions after having checked certain system functions. This saves fuel and reduces the impact on the environment. Thanks to the Eco-Silent Mode the engine speed can be lowered to a predefined required level resulting in a significant decrease in diesel consumption and noise emission without any negative effects on operational output.

Fitted with diesel engines of the new generation, the three Bauma exhibits work with lowered engine speed. This results in a further reduction of fuel consumption and an increase in efficiency. For the HS 8130 HD duty cycle crawler crane the hydraulic system was optimized and so the machine achieves a higher material handling capacity than its predecessor despite lower engine power.

Multi-function machine LRB 355 The robust undercarriage of the new piling and drilling rig LRB 355, with the longest tracks in its class, guarantees a high level of stability. Thanks to the parallel kinematics the machine has a large operating area. Another aspect relates to the direct mounting of all winches on the leader. On the one hand, this allows for a direct view from the operator’s cab to the main winch and, on the other hand, ensures that the ropes do not move during leader adjustment. The optional elevating working platform of the LRB 355 enables safe and easy access to the attachments. Additionally, it facilitates the assembly of tools, as well as maintenance work at the jobsite.

3D computer graphic of Liebherr duty cycle crawler crane HS 8130 HD with casing oscillator.

The LRB 355 is available in two different configurations with a maximum height of 33.5 metres and a maximum weight of approximately 100 tons without attachments. The rig is driven by a powerful V12 diesel engine offering 600 kW (option: 750 kW), which complies with the European emission standards, stage IV, and the US Tier 4 final.

Further major advantages of the new piling and drilling rig are its fast mobilization and easy transportation. The rig can be transported with the leader and multi sledge attached to the machine. In order to minimize the transportation length to a mere 22.6 metres the leader can be folded. In addition, no tools are required for folding the leader and mounting the counterweight. The LRB 355 has been specially designed for drilling with full displacement tool and achieves a torque of 450 kNm in this application.

The rig can, however, be used for numerous other applications including drilling with Kelly equipment, double rotary head and continuous flight auger, soil mixing, as well as piling jobs with vibrator and hydraulic hammer.

Versatility as trump card for tough job site tasks: HS 8130 HD duty cycle crawler crane The Liebherr duty cycle crawler crane, type HS 8130 HD, can be used for various deep foundation applications, as well as for the typical material handling tasks of a duty cycle crawler crane. These include working with slurry wall grab up to 35 tonnes and casing oscillator up to three metres, material loading with grab or dragline bucket, dynamic soil compaction, as well as various dredging applications.When developing the 130-tonne duty cycle crawler crane Liebherr paid special attention to the robust design of the steel fabrication, the optimization of performance and safety as well as to easy and quick transportation and fast set-up of the machine.

The HS 8130 HD can be transported with the railings, catwalks and pedestals fully assembled on the upper carriage. This accelerates the mobilization of the crane on the jobsite.

Further features that facilitate the mobilization are the self-assembly system for crawlers and counterweight as well as the telescopic jack-up system.

Additionally, the HS 8130 HD can be easily transported thanks to the low transport weight of only 50 tonnes and to the maximum transport width of the basic machine at 3.5 metres.

LB 36: well tried and tested rotary drilling rig With the LB 36 Liebherr also displays a well-established rotary drilling rig at Bauma 2016. This rig is fitted with the BAT rotary drive, which was first presented three years ago, and offers a torque of 410 kNm and can be individually configured depending on the type of application. The main advantages of the hydraulic drive manufactured by Liebherr are automated torque adjustment, continuous speed optimization and four electronically adjustable speed ranges. Further assets of this rotary drive are its simple structure, its low maintenance requirements and, above all, its exceptional efficiency.

The LB 36 weighs 115 tonnes and has been designed for drilling diameters of up to three metres and drilling depths of maximum 88 metres. The powerful Kelly winch with 40 tonne line pull and the rope crowd system with 40 tonne pull force offer a significant technical advantage. This provides the operator with maximum performance and reliability even with the most difficult soils and extreme operational conditions.

The Liebherr drilling rig convinces with the solid leader design, robust kinematics and a large range of possible applications. High stability is also provided thanks to the large footprint of the undercarriage. Similar to the other machines of the LB series the LB 36 is specially designed for Kelly drilling, continuous flight auger and double rotary drilling as well as soil mixing work.

Liebherr – a full-service provider in the deep foundation industry In the field of deep foundation work Liebherr offers its customers not only numerous machines, but also a large number of services, enhancing efficiency on the jobsite. These include technical consultation in the planning stage, application consulting on the jobsite, recording, evaluation and transfer of machine data via LiDAT, as well as the documentation and analysis of the processes on the jobsite via PDE/PDR. A particular highlight is the new Liebherr simulators for deep foundation machinery. The operators can prepare for their future tasks in a virtual but realistic environment. This improves both the operator’s self-confidence, as well as safety on the jobsite. l
