INVESTING IN INFRASTRUCTURE WILL SECURE CANADA’S GROWTH ECONOMY Setting national goals around building sustainability into our infrastructure is key to our future economy. The economy needs reliable infrastructure to connect supply chains and efficiently move goods and services across borders. The funds must be predictable, flow quickly, and be aligned with provincial, municipal, and Indigenous needs. The creation of an independent advisory body can align governments at the provincial and municipal level to address infrastructure deficits across Canada. The stability of having multi-year project pipelines, based on evidence and independent expert advice, would also enable the development of the necessary skilled workforce and encourage private sector investment.

ECA expands into Western Canada
ECA Canada currently supports Eastern Canada from its Ontario branch (pictured), but a new facility will be established in the Vancouver area with sales, parts, and service for all product lines to service its new Western Canada territory.
Equipment Corporation of America (ECA), leading distributor of specialty foundation equipment, has been awarded the sales territory of Western Canada by BAUER Maschinen and BAUER Equipment America. The official announcement was made at the company’s annual sales meeting in Florida in January.
ECA has been serving Eastern Canada as ECA Canada Company since 1999 through its Uxbridge, Ontario headquarters. As one of the largest BAUER distributors in the world, this was a natural progression for BAUER to grow its presence in Manitoba, Saskatchewan, Alberta, and British Columbia.
Foundation contractors in Western Canada can expect the same wide range of equipment, services, and parts ECA and ECA Canada offer in the Eastern United States and Canada.
ECA is planning to open a full-service facility in the Vancouver area with sales, parts, and service for all product lines. While existing employees will have an opportunity relocate, ECA is poised to hire several local people to staff the new branch.
“We’re very excited about expanding our operations into Western Canada!” says President/CEO Roy Kern. “We’ll be locally supplying and stocking a full complement of BAUER products and accessories, including BG drilling rigs, RTG piling equipment, KLEMM small diameter drills, BAUER MAT/ Obermann slurry handling, mixing, and pumping equipment, MC duty-cycle cranes, and cutters.” 8 PIC Magazine • June 2022
“The company has a long history of providing excellent service; the most technologically advanced and robust equipment and accessories; large parts inventories; well trained, knowledgeable and courteous staff; and extensive project application expertise,” says Kern. “We now look forward to providing that same focus and energy to assist Western
Canadian contractors in the efficient and profitable installation of foundations, shoring, and ground improvement.” ECA has been a leading supplier of foundation construction equipment for more than a century. They’re the exclusive distributor for BAUER Drilling Rigs, KLEMM Anchor and Micropile Drilling Rigs, RTG Piling Rigs, and BAUER MAT Slurry Handling Systems. They also distribute HPSI Vibratory Pile Hammers, WORD International Drill Attachments, Dawson Construction Products, ALLU Ground Improvement Equipment, Pile Master Air Hammers, DIGGA Dangle Drills, Olin Concrete Pumps, and KB International synthetic polymer slurry. ECA offers sales, rentals, service, and parts from nine facilities throughout the Eastern U.S. and Canada.

The Pattullo Bridge replacement project
When complete in 2024, the Pattullo Bridge replacement will connect Surrey and New Westminster across the Fraser River
N
amed after British Columbia’s 22nd premier, Duff Pattullo, the Pattullo Bridge has been a
historic connection across the Fraser River between two Metro Vancouver communities − Surrey and New Westminster − since 1937. But now, after 85 years of service, the venerable, 1,227-metre arch bridge starting to show its age. The Pattullo Bridge is among the oldest bridges in Metro Vancouver and has exceeded its designed end-of-life by more than 30 years, and simply does not meet many modern design standards. The existing deck’s four lanes are too narrow and are missing a centre median barrier. Additionally, the current bridge only has a single narrow sidewalk for pedestrian and bicycle use, with no barrier protection from incoming traffic. 10 PIC Magazine • June 2022
Because of this, it was announced in 2018 that the B.C. government would be moving forward with the construction of a new $1.377 billion Pattullo Bridge replacement approximately 100 metres upstream of the existing bridge. “This is an essential transportation link that British Columbians rely on, and it’s our job to make sure it’s safe and gets people moving better,” Premier Horgan said in a press release at the time. “Replacing the Pattullo Bridge will help people get home to their families quickly and safely, while creating good jobs for local workers.” The Pattullo Bridge Replacement Project is being delivered solely by the Province of British Columbia through Transportation Investment Corporation (TI Corp), which has been tasked with overseeing the construction. When complete the new Pattullo Bridge will
By Paul Adair be owned, operated, and maintained by the B.C. Government. Fraser Crossing Partners (FCP) − a joint-partnership between Acciona Infrastructure Canada and Aecon Constructors − was selected to undertake the design build finance contract, with the long-span bridge design by Leonhardt, Andrä und Partner Beratende Ingenieure, Hatch Corporation, and EXP Services. The new bridge will run approximately 1,235 metres across the Fraser River and include a 530-metre-long, cable-stayed main span that features four lanes built to modern safety standards. And while the new crossing will open with two lanes in each direction, same as today, it will now include a centre safety median barrier and wider lanes to accommodate both passenger and commercial vehicles, as well as have walking and cycling lanes on both sides of the bridge that are separated from traffic.
“The new Pattullo Bridge has also been designed to be expandable to six lanes if future capacity requirements are higher,” says Wendy Itagawa, Executive Project Director, Pattullo Bridge Replacement. “This will be achieved by converting the outside bridge multi-use pathways into two new traffic lanes and constructing new multi-use pathways by cantilevering out from the existing superstructure.” On the Surrey side of the river, the Pattullo Bridge replacement will connect directly to King George Boulevard and Highway 17, as well as to new and existing multi-use paths. On the New Westminster side to the north, the bridge will link with new walking and cycling paths (including four new multi-use pathway bridges) in addition to urban integration enhancements, such as new landscaping and landscaped boulevards, and new amenities for pedestrians and cyclists. For vehicles, travel will be
made safer and more efficient going to and coming off the bridge on the New Westminster side with direct connections to and from Royal Avenue, McBride Boulevard, and East Columbia Street, which includes a new direct off ramp connected to the latter. Currently the in-river bridge foundation work is well underway. The pile driving is complete on the 27 in-river piles for the foundation set to support the main tower of the new bridge, with the deepest piles installed to a depth of approximately 75 metres, and in early April crews completed a continuous 36-hour concrete pour to finish the cap pile. Construction will now begin on the 170-metre bridge tower using self-climbing formwork and a tower crane. Once the tower construction has progressed to a certain elevation, crews will then begin construction of the lower and upper crossbeams. Further pile
installation work will also begin on the secondary in-water pier this summer. “The deck construction is expected to start in early 2023 using the balanced cantilever method, and the deck will be supported by three sets of longitudinal steel girders with transverse floor beams and constructed using pre-cast concrete panels,” says Itagawa. “The cable-stayed span will be supported by 80 cables in a dual-plane, semi-fan arrangement, and the H-shaped tower was selected to avoid any cables being above the road due to the risk of ice accretion.” In New Westminster, site preparation work continues and the construction of two on-land bridge foundations is underway. Drilled-shaft methodology is being used instead of pile driving to minimize noise and vibration for nearby residents. In Surrey, construction is underway on Piling Industry Canada • June 2022 11
nearly all seven bridge foundations, as well as the bridge abutment and offramp structures. Upcoming activities include continued construction of bridge foundations and approach structures, and site preparation, utility relocations, and road work. The Fraser River is the longest river in the province with high water flow velocities, and the replacement bridge has been designed to have a much smaller footprint in the water, consisting of a single tower and one additional pier, which has many advantages such as, less construction time in the Fraser River, easier navigation of the river for marine users, and a reduced impact on aquatic life. Doing this, however, required substantial research into the effects of the size and position on the structures downstream from the bridge.
“The bridge hydraulic effects have been a key design element to ensure no adverse impacts due to scour and sedimentation on downstream structures and navigation channels,” says Itagawa. “As part of the project, we built a 1:80 scale model of the bridge foundations in a lab in Vancouver to model different hydraulic scenarios and this, combined with the numerical modelling, has informed the bridge foundation and scour protection design.” Another important component of the project has been centred on urban integration and the creation of improved walking and cycling paths that connect to − and from − the bridge. As part of this, the project team has spent more than a year performing extensive technical analysis that will provide the best active transportation connections for all ages and abilities.
“Given some technical and terrain considerations in the area, active transportation groups were engaged throughout the process, which has resulted in several design improvements to multi-use paths, including additional paths and more direct connections for walkers and cyclists,” says Itagawa. Sustainability and protecting the environment has also been top of mind throughout the course of bridge construction, and the project has gone through both provincial and federal permitting processes and environmental assessments. These assessments have reviewed many aspects of the potential environmental/social impacts of the project, including fish and fish habitat, marine use and navigation, archaeology, traffic, and noise, and some of the requirements that have come out of the permitting process include maintaining access to navigation channels for marine

users and limiting work in the river to the least risk fisheries window, which annually runs from mid-June until the end of January. “One of the major considerations has been the protection of the river’s aquatic life, including the need to have as little impact on it as possible as per various provincial and federal mandates,” says

FRPD’s versatile fleet is ready to complete all scope and size Marine Construction, Environmental Remediation, Dredging and Land Foundation projects.

Itagawa. “To minimize disturbance to fish during in-river bridge foundation works, the contractor is using an underwater noise mitigation system. This system includes a confined bubblecurtain system which dissipates the underwater noise around the piledriving work areas.” Work on the Pattullo Bridge replacement is expected to wrap up and be open to traffic in 2024, at which point the existing bridge will begin to be removed. l

EQUIPMENT Profile
Workout with 100 tonnes: LR 1100.1 The quick availability of crawler cranes is a decisive factor in the 100-tonne class − a requirement that the new LR 1100.1 fulfils perfectly making it the ideal multi-purpose crane on any construction site The new crawler crane LR 1100.1 is optimized for all typical lifting applications in the 100-tonne category. It can be configured either with a main boom up to 62 metres or with a main boom up to 44 metres in combination with a fixed jib up to 20 metres. The LR 1100.1 is fitted with the most powerful engine in its class: 230 kW provide the necessary performance for the lifting operations. Thanks to the Eco-Silent Mode, the engine speed can be reduced to a predefined level. This means that diesel consumption and noise emission are reduced; nevertheless, the performance remains the same. The Automatic Engine Stop Control offers a further economic and environmentally friendly solution. After checking certain system functions, the engine is switched off during longer work interruptions.
EVERYTHING IN VIEW The crawler crane is optimized for quick transfer between construction sites. The transport width is 2,983 or 3,500 millimetres, depending on whether the crane is transported with

or without crawlers. At the construction site, the assembly of the LR 1100.1 is simplified through the self-assembly system and radio remote control. Radio remote control allows the crane operator a high degree of flexibility and additional safety even during operation. The crane can be operated from outside the cabin and so allow for a better overview of the construction site. So-called blind spots can thus be better avoided. Depending on the application, a second person is no longer required to assist with hand signals during lifting operations. The cabin of the new crawler crane can be elevated by 2.8 metres, thus allowing for a good allround view.

industry. This year’s award for the Safety category was won by the LR 1400 SX. A crawler crane from Liebherr-Werk Nenzing GmbH has thus secured an award two years in succession. “Safety was always an important part of our product development,” said Gerhard Frainer, Managing Director for Sales at Liebherr-Werk Nenzing GmbH, during the awards ceremony. “In recent years, we have focused even more strongly on this with digital solutions and assistance systems. It is important for us that those who operate our cranes feel safe on the jobsite. We want to continue to successfully follow this path.” The LR 1400 SX extends the range of crawler cranes from Liebherr-Werk Nenzing GmbH to include lifting capacities up to 400 tonnes. The crane designers paid particular attention to the safety concept.
The Ground Pressure Visualization of the LR 1400 SX calculates the current ground pressure of the crane in real time and compares it with the specified safety limits of the relevant position. The ground pressure is displayed in the operator’s cabin. This means the operator is permanently aware of whether the machine is situated in, or is approaching, a critical area. When erecting or lowering the boom, the Boom Up-and-Down Assistant indicates the approach to the tipping border and automatically stops operation before the operator unintentionally enters an unsafe zone.
“The winning LR 1400 SX is only one example of maximum safety. All our cranes in the LR series are equipped with the same safety systems and fulfil the same criteria. The award is an expression of appreciation for our commitment to safe crawler cranes and construction machinery,” says Gerhard Frainer. l

driving timber, h-pile, pipe, and prestressed concrete piles. With an optional sheet pile adapter, the Pile Master is also a great choice for driving steel sheet piles in soil conditions where a vibratory hammer cannot drive the sheets to the required depth. Hammers can be guided for use with 21” or 26” pile driving leads or freely suspended with an extended base. Pile Master air hammers are known for their efficiency—producing up to 90% energy transfer into the pile while using an air compressor as small as 185 CFM. Request more information today.

Giken Reaction Base System components.
The press-in piling machine produced by Giken installs the first few piles by clamping onto a steel frame called a reaction stand, which has arms on both sides for counterweights to sit on. Once the first few piles are pressed in this way, the equipment starts to grip from on top of the installed piles to move forward on its own as the pile installation progresses.

Hydraulic pumps powered by a diesel engine in a sound attenuated power pack send pressurized hydraulic fluid to the piling machine as the energy source. A plant-based biodegradable hydraulic fluid and grease are also used for environmental considerations. By avoiding vibratory or percussive forces to install piles, this method generates
much lower levels of noise and vibration during installation compared to traditional pile driving methods. The advantages of the press-in piling method over conventional piling are: • Being low noise and practically vibration free, which enables piling projects to be carried out close to houses, schools, hospitals, and other sensitive structures, as well as in areas with sensitive and protected fish and other animals.
Seawall cross section, during and after construction.
• The equipment size is relatively small and its clamping points on piles are much lower than those of other pile driving methods. This feature enables the equipment to work in physically tight working conditions, both horizontally and vertically, such as under railway girders or right next to existing structures or railroad tracks. • With a high-pressure water jet attachment or a crush auger attachment, the press-in machine can install piles into dense sand, stiff clay, gravel, cobbles, boulders, and soft rock with equivalent N-values much higher than 50 and a uniaxial compressive strength of five to 10 ksi (approximately 35 to 70 MPa); thus, piling can occur without mobilizing another set of machinery for predrilling. The maximum depth that the auger can

bore is approximately 75 feet (23 metres). • The method can achieve much more accurate and safer pile installation due to a combination of better control of the piles and lower clamping points.
GYROPRESS METHOD A Gyropress machine is a variation of press-in piling equipment for installing a pipe pile by rotating and simultaneously pressing piles in. A sacrificial cutting shoe is welded at the toe of each pile to facilitate installation. The reaction force comes primarily from friction between the two or three already-installed piles and the surrounding soil, while the machine rotates and presses in the new pile. A combination of the cutting shoe and the fact that the new pile is being rotated reduces press-in resistance without loosening soil. In fact, this system allows a pile to be installed even in very hard soils and existing reinforced concrete structures, sometimes by using a heavy-duty cutting shoe. As with other Giken-type press-in piling machines, the Gyropress equipment (which Giken co-developed) does not require a service crane to move forward or backward from one pile installation to another. This capability becomes critical when the overhead clearance is limited, such as in the first case study presented.
Pipe pile installation along coastal highway.
The Giken Reaction Base (GRB) System involves a press-in piling machine with a power unit, a clamp crane, and a pile runner; all work and move on top of an already installed line of piles, using that line as a narrow construction staging area as well as an access path. The pile runner hauls piles from what can be a faraway access point by travelling along the piles to the clamp crane, which picks up a pile or piles and brings them to the piling machine. Once these pile sections are fully unloaded, the pile runner goes back to retrieve the next batch of piles. This system enables pile installation on projects even where construction access is impossible or extremely difficult to secure, such as in the following case study projects.
would be the only safe, reliable solution to expediently protect the exposed abutment because of the very steep, unstable slope created by the flooding right underneath it, in addition to extremely tight construction access.
PROJECT LOGISTICS The bridge has a slightly curved 138 feet (42 metres) long single span with a two-lane highway supported by its concrete girder. Fifteen pipe piles were pressed in to form a very solid earth retaining structure. The piles’ diameter was 59 inches (1,500 millimetres), and their length varied from 50.8 to 80.3 feet (15.5 to 24.5 metres), with a wall thickness of from 0.59 to 0.83 inches (15 to 21 millimetres). Each pile was spliced once, twice or three times depending

on the pile’s location and overall length.
The Kyushu region of southwestern Japan experienced very heavy, continuous rain in a short period of time in June 2016. More than 250 millimetres (9.8 inches) of precipitation was recorded during a 24-hour period in the City of Kagoshima, where the Uto Bridge is located. The bridge section of the regional highway was immediately closed when deep erosion of the slope just in front of one of the bridge abutments was reported. The highway agency in charge determined that a pressed-in pipe pile retaining wall
The pile driving was started from the downstream side because of easier logistics compared to the other side. The Gyropress machine was assembled on the reaction stand, which had been set on flat land prepared on the downstream side of the abutment (left side in the photo). The soil consisted of weathered to fresh sandstone covered with a thin surface clay layer that had been spared from the stormwater. The sandstone was expected to have an average equivalent N-value of 275. The self-standing height of pile No. 7 was as much as 39.3 feet Piling Industry Canada • June 2022 25

under the bridge. A challenge was finding a practical way to bring the piles to the Gyropress machine for installation under the girder. A clamp crane was mobilized to supply the section involving piles No. 10 through 15, which were installed under the bridge girder. The crane was first assembled on piles No. 1 through No. 3, adjacent to the abutment, after these piles were installed. Then the Gyropress machine was moved forward to leave these pile tops unoccupied. The crane was equipped with a Y-shaped boom end, allowing it to lift and hold one end of pipe section within the minimal overhead clearance. The heaviest section lifted by the crane on this project was slightly more than 11,000 pounds (five metric tons).
HIGHWAY SEAWALL RETROFIT The City of Kamakura, located approximately 40 miles (65 kilometres) southwest of downtown Tokyo, has been one of the major tourist destinations in the region thanks to its abundant cultural and historical heritage aspects, as well as a scenic beach facing the Pacific Ocean. The agency in charge of National Route 134, a two-lane coastal highway, planned to mitigate chronic traffic jams on the 0.85 miles (1.4 kilometres) long section in the city by widening a sidewalk, adding a turning lane at two locations, and reconstructing the deteriorated earth retaining seawall that abutted the highway above. However, local residents and an environmental group had voiced concerns that the highway-widening

term closure due to geographical constraints and constant traffic flow in both directions. At the same time, local residents expressed their desire to keep open as much beach area as possible during construction. Commonly utilized earth retaining wall types such as a reverse-T cantilever concrete wall, a sheet pile wall with earth anchors and a concrete gravity retaining wall were not applicable due to the project’s difficult site conditions. As a result, press-in piling with the GRB system was adopted to satisfy these seemingly conflicting project requirements, including by keeping the piling operation’s footprint at a minimum. The highway widening for the turning lanes required an additional right of way of 1,980 yd2 (1,660 m2) in the beach area. However, installation of the new vertical pipe pile seawall with the pressed-in method and subsequent removal of the sloped portion of the existing seawall increased the beach area by 864 yd2 (723 m2), partially offsetting the beach area’s decrease. Direct installation of pipe piles into the existing concrete seawall eliminated the need for temporary shoring during and after construction. That is, the self-

pressure from the embankment carrying the highway. As a result, the highway remained open to traffic and public beach access was maintained (except for the staging areas and a narrow strip of construction zone against the seawall).

SOILS AND CONSTRUCTION Although the highway was on the embankment made of soft fill materials, beach sand was relatively thin (a meter or less for most of the alignment) and was underlain by weathered mudstone with equivalent N-values up to 300. The new seawall’s exposed height varied between 15 and 23 feet (4.5 and seven metres), depending on the locations. Longer piles were spliced once, while shorter sections were installed as a whole. Cosmetic cover concrete was cast against the pipe pile wall for the entire height, except for the top 3.3 feet (one metre), which was later covered with capping concrete.
CONCLUSION Using pressed-in pipe piles for earth retaining is a highly effective method for repairing or retrofitting existing structures such as bridge piers, abutments, levees, and seawalls — especially when the existing structures cannot be removed before their repair or upgrade.
