Editorial Comment New Year. New Beginning? With the start of 2014, can we believe the various comments on market recovery? As this issue illustrates with its numerous site reports, there is certainly a lot of activity going on around the world. With ConExpo just around the corner, there is also the usual flurry of new equipment as manufacturers make last minute introductions to meet the imminent new emission regulations. And if the rapidly increasing readership of Contractors World International is any indication, there are a lot of people looking for cost efficient solutions. This issue has been distributed to 98,413 individuals around the world. This makes the magazine, by a significant margin, the world’s most widely read title serving the construction and related industries. It is also proof that the industry is more than willing to accept digital publications and the rich content they make possible. Interesting New World The world that emerges from the global recession will be much different to the past. The projects will be more demanding with technology playing an ever increasing role. There will also be a widening differential in machine specifications as the markets come to terms with two very different standards. This has forced manufacturers to develop two ranges - one to meet Tier IV emission standards and another to meet the much lower standards that are essential in some key markets. I do not see any massive innovations from the industry. Contractors and manufacturers will focus on more efficient solutions that do not impact on productivity. Health and safety will continue to be an issue as more and more countries are coerced into implementing the most basic of safety regulations. Banning use of child labour would be a good start.

ZX290LC-5 assigned to railway project A new Hitachi ZX290LC-5 has been assigned to a tunnel construction project under the main railway line in central Norway. Farbu & Gausen has added the Zaxis-5 medium excavator to its expanding fleet of construction machinery. Prior to the construction of the tunnel, a local farmer had to cross the track to gain access to his land. The critical part of the project involved the closure of the track from the Saturday morning (at 6 am) until the Sunday night (at midnight). This enabled Farbu & Gausen to remove 30 m of track, excavate the tunnel, and lift the framework for the interior of the tunnel into place. The contractor then added the concrete to reinforce the structure, installed the safety barriers alongside the railway line and finally laid the tracks back in place. An access road linking one side of the tunnel to the other was also constructed. More information >>> Hitachi Construction Machinery Contractors World - International Vol 5 No 1

Big Power Pack for Putzmeister Recently Putzmeister Concrete Pumps GmbH supplied an unusual PUMI. The truck mixer concrete pump was constructed for Kjell Magne Gronli in Norway on a 1+3 Volvo chassis. For the Putzmeister engineers and fitters this was not an unusual order on first glance. On a closer look at the specification they were impressed: The engine of this model delivers 750 HP (551 kW). Kjell Magne Gronli ordered the FH 16 750, the strongest possible engine, with a cubic capacity of 16 litres and massive torque; a 28 m placing boom and a 9 m³ mixer drum delivering 3,350 Nm. Why buy such a power pack? The customer was won over by its new Intermix truck mixer on a Volvo chassis. The local conditions around Haugesund also played a role. At such power, the unit easily tackles every task. Kjell Magne Gronli said “The reason I decided to purchase this Volvo chassis was my Intermix truck mixer. It has a triple axis, 3.3 m wheel¬base, 660 HP, the automatic Volvo I-shift transmission, rear air

suspension, a drum with a volume of 9 m³ and telescopic chute.” “For me it was obvious to purchase another Volvo vehicle when I received a new contract from NorBetong AS in Haugesund.” “When it came to the decision of the actual work machine, the concrete pump, there was no doubt: It had to be Putzmeister.” “Reliable, good to drive, superb solutions for daily work. High range, 5.5” feed pipe, large hopper with powerful agitator and excellent pump power. But it was mainly quality that was key.” “Now I look forward to my work at the coolest workstation in all of Norway.” More information >>> Putzmeister

Terex All Terrain Crane Works At The Pantheon “To the great men of this Country, in gratitude” states the inscription on the massive plinth of the Panthéon. Built between 1758 and 1790 by the French architect, Soufflot, on the hill known as the Montagne Sainte-Geneviève, the neo-classical structure was meant to be a church dedicated to the patron saint of Paris. With the passing of the years, the pressure on its arches, water seepage caused by leaky joints and the corrosion of swelling metal components, which have cracked open surrounding stone, has compromised the stability of the structure. The main caretaker for the national monument system, has now undertaken a massive restoration project. The first phase of this restoration work will last until 2015, starting with the upper part of the structure at 82 m high (nearly 270 ft). The Panthéon is fragile, and in order to repair its upper structure without using the historical building itself as a support, the colonnaded drum supporting the dome will be completely covered by free-standing scaffolding. In order to raise the 350 tonnes of scaffolding into the air, Paris Echafaudage designed a metallic structure shaped like a kitchen stool. It consists of a reinforced hoop tightened around the base of the drum and resting on four legs, each 37 m high and anchored by micropilons. The French construction group, Ponticelli, deployed its Terex AC 700 All Terrain crane to Page 8

I n order to assemble the scaffolding, Ponticelli configured its AC 700 with a 42 m luffing jib and 140 tonnes of counterweight. “Obtaining the permits necessary to truck in and install this kind of equipment in the heart of Paris was no easy thing. But it turned out to be the best option for this type of project,” explained Stéphane Yorgui from Ponticelli’s engineering office.

individual structures into their desired positions. The largest of these structural elements were 20 x 20 m in size, weighed 42 t and had to be hoisted to a height of 40 m To cope with different lift profiles, the team used the 42 m luffing jib and worked with varied main boom extensions and angles. As the crane was working all around the Pantheon, the crane had to be repositioned for every lift. This was a major consideration when choosing which crane configuration to use, as the time required to partially dismantle the crane each move would have impacted on the overall project schedule. With the chosen configuration, Ponticelli’s team needed to only remove 80 tons of counterweight to move the crane, as the AC 700

New Holland fleet for infrastructure projects In its largest investment in Moldova’s infrastructure to date, the European Bank for Reconstruction and Development (EBRD) is extending a Euro150m loan facility to the Moldovan government for the rebuilding and repair of up to 200 km of major motorway network. In addition, the US Government’s Millennium Challenge Corporation (MCC) is investing US$132m in its Moldovan Compact agreement to rehabilitate 93 km of the M2 and R9 roads between Sarateni and the city of Soroca. A consortium of international contractors has already commenced work on several of the road construction and repair projects, using a fleet of 18 New Holland construction machines that have already been delivered to site. Among the equipment are two F156.7A motorgraders, two W300C wheeled loaders, four W190C loaders, two WE150B wheeled excavators, four B115C backhoe loaders and four L220 skid steers. “A well-functioning transport system is

critical for economic growth, and improving Moldova’s road infrastructure is one of my government’s key priorities,” said Prime Minister Iurie Leanca. “We expect about 1,000 jobs to be created by this investment and it will reduce business costs and increase productivity, creating economic growth and prosperity for all.” The EBRD loan will be used to rehabilitate sections of the R33 Hincesti-Lapusna M1 road to the Romanian border, the R14 Balti-Sarenteni transport link between the capital Chisinau and Moldova’s second largest city Balti, the R9 SorocaArionesti road in the north of the country and the R34 Hincesti-LeovaCantemir road in the south. The loan will also help to fund the new 17 km M3 Slobozia Mare bypass. “Located at a geographical crossroads and bordering the European Union, Moldova’s roads are becoming increasingly important for the economic development of the country and the wider region,” said Julia Contractors World - International Vol 5 No 1


Otto, head of the EBRD Resident Office in Chisinau. “Better roads will help spread economic development to remote regions, will bring producers closer to their markets and will take people to their destinations more safely.” Right Equipment for the Right Job At 27.3 tonnes, the W300C is New Holland’s largest wheeled loader, boasting a 5.0 m³ bucket and a 9.1 tonne bucket payload. The

W190C loader weighs 18.3 tonnes and delivers a 6.4 tonne bucket payload, also with Tier 4i SCR technology, making it an ideal machine for stockpiling and loading duties. New Holland’s F156.7A is one of the most productive motorgraders, with an operating weight of 16.2 tonnes and a 173 hp (129 kW) dual-power low emission engine.

Vogele paver revamps areas at Ludwigsburg Palace grounds For contractors, Gottlob Brodbeck GmbH & Co. KG, rehabilitating the footpaths rehabilitated and entrance area redesigned at Ludwigsburg Palace grounds called for immaculate paving results so that the new coloured asphalt areas blend perfectly into the historical ensemble.

Once the residence of the kings of Württemberg, today, the sumptuously appointed rooms are used for state receptions and cultural events. Contractors World - International Vol 5 No 1

Panorama The expansive palace grounds are open to the public and the permanent garden show is a popular attraction for locals and visitors, especially in summer. A number of pavement rehabilitation measures were recently implemented in the south gardens of the park. These included the redesign of the entrance area and rehabilitation of the gravelled footpaths with coloured asphalt, as they often became muddy in bad weather. Manoeuvrable compact paver This project was ideal for the Vögele dash 3 paver -SUPER 1303-3i. The highly manoeuvrable wheeled, compact paver was designed specifically for construction jobs like these. Jernail Sing defines the requirements, “The most important factor for us in this project was that the screed worked perfectly and ensured maximum evenness. This is crucial as coloured asphalt is a very unforgiving material.” Any concerns he may have had vanished as the AB 340 TV fulfilled all expectations. The required evenness of +/- 3 mm over a

longitudinal distance of 3 m was complied with flawlessly and a crown with a 2% slope was also finished in perfect quality. Uniform heating One key factor for the outstanding result was the new electric screed heating system. It benefits from a significantly reduced warmup time and the particularly uniform heating of screed plates and tamper bar. Both of these factors were decisive in producing an extremely uniform pavement surface. Small transport width The small transport width of the paver, just 1.85 m, was another major advantage when manoeuvring between bollards and ticket kiosks. In fact, the Brodbeck team reduced the width even further by temporarily removing the mounts for the automatic grade and slope control system. “It only took a minute,” says Schifer.

New milestone lifting the widest tilt-up panel so far A remarkable performance has recently been achieved by a Liebherr crawler crane in the United States. An LR 1300 crawler crane, designed and manufactured in the Liebherr plant in Austria, lifted the widest tilt-up panel in history. With a total width of 27 m (89 feet) the old world record was beaten by 1.88 m (6’ 2”). This new world record was set in Rock Hill, South Carolina, by Citadel Contractors Inc., an Apex, NC company which specializes in tilt-up construction for more than 15 years. The 27 m (89’) wide and more than 9.14 m (30’) tall panel had a weight of approximately 58, 970 kg (130,000 lbs). Among the main advantages of tilt-up construction for end-users is their rapidness and their cost-effectiveness. Techniques for tilt-up construction have been further developed in recent years, making it suitable for a great number of buildings. Most of the work is done on ground level, thus making it a fast, safe and efficient technique. However, it requires careful planning and a high-performing crane to do the lifting. The LR 1300, one of Liebherr’s most successful models, was the perfect crane to set this outstanding world record. This 330 ton capacity crawler crane not only offers high productivity, but also quick and easy transport and assembly. Jason Swagert, Vice President of Citadel adds that the LR 1300 gave them the unique opportunity to do bigger and heavier tilt-up panels due to its outstanding load-chart. “The operator also loves the crane due to its ease of operation and all important machine data can be accessed from our office via the onboard LiDAT system”, says Swagert. “The winches have higher line pull and are faster than other machines in this class – which makes it also the perfect machine for us for hanging steel.” Another distinguishing feature of the LR 1300 is its enormous number of boom and jib configurations and thus potential applications. The combined length of main boom and luffing jib can be as much as 172 m (564 ft). This panel will be part of a new high school building in Rock Hill. It was the fourth building on the campus – the other three were already built last year. For more information >>> Liebherr Cranes

Solution For Difficult Dutch Rail Construction Problem – Saving Manpower And Man Hours


ost-tensioned cables prove no problem for hydrodemolition specialist Aqua Demolition Services (ADS) when exposing the steel cables. This was necessary to allow inspection before connecting a new elevated concrete deck and rail tracks in Amsterdam; eliminating the need for up to 10 hand lance operators and saving almost 2 weeks lance operations. An existing elevated rail decking in Holland presented demolition problems for the contractor, BAM Civiel bv, in making ready for joining it to a newly constructed concrete deck and new twin railtrack.

Page 14

Erected over 20 years ago, the old reinforced concrete deck - above the busy A10 highway through the southern suburbs of South Amsterdam - included two post-tensioned cables. After removing a balustrade/end wall at one end of the old deck using a conventional concrete wire saw, it was necessary to remove more of the deck concrete to expose the rebar for reinstalling to the new adjoining deck. However, a bigger problem was exposing the post-tensioned cables for inspection prior to re-casing in new concrete, without any damage, whatsoever, to the steel cables and rebar. Specialist contractor, Aqua Demolition Services (ADS), provided the solution with hydrodemolition techniques using two Aquajet Systems Aqua Cutter 710V robots’. “Without these, probably the only other solution would have been to use hand lances – taking 8-10 operators at least 2 weeks to safely clear all the specified concrete” explained ADS Director, Arjan de Waard “Using Aquajet’s hydrodemolition techniques allowed us to complete the job inside 1½ days including set up time.” The first post tensioned cable was Contractors World - International Vol 5 No 1

located 50 mm below the surface of the 12 m wide x 27 m long concrete deck. Comprising some 12 bundles of cable to give a total diameter of 140 mm, the post-tensioned cables were ‘tied` in to a steel plate. Once inspected, the cables will be re-cased in new concrete and the steel plate removed. “We were extremely worried about initially removing the concrete as the client, the rail authority O.V. Saal, had specified there must be no damage to the steel cables. However, the fears proved unwarranted as the cutters removed all the concrete cleanly, leaving the steel cables totally exposed and undamaged” said Bam Civiel Project Manager, Leen van Anrooij. A second, similar sized post-tensioned cable was located some 600 mm below the first cable. Access to this one, however,was close to the elevated deck’s columns and beam above the pile cap and, once again, the client specified no damage to the beam behind the contoured deck.

“We opted to tackle this problem by using a second Aqua Cutter installed with a 7 m vertical mast” explained ADS CEO Hans van‘t Geloof “Not only did it ease the demolition process from the front of the 900 m deep deck, it also allowed us to progress at a faster rate with no damage to the beam wall.” Hydrodemolition works by pressurising and widening existing pores and microcracks in a concrete structure using highpressure water penetration. The rate of removal is dependent on the amount of water directed towards the concrete surface, and consequently the area and depth of removal can be closely controlled. Using a high pressure water jet also makes it easy for the operator to work around obstructions; particularly when

compared with, for example, conventional jackhammer methods. “With hydrodemolition, once programmed the jet moves rapidly and continuously over the selected area for removal,” explained Hans. “There is no percussive effect on the surface, with the water jet penetrating the deteriorated concrete, and there is no modification of the concrete microstructure or pore structure. “Apart from very effective cleaning there is also no effect on the rebar.” Both hydrodemolition units, from Swedish specialist manufacturer Aquajet Systems, operated at a pressure of 1040 bar and 261/min of water. In accordance with all environmental specifications, ADS was responsible for bringing to site its own water supply and, using eight 35 m³ tanks to transport contaminated water off-site for treatment. Bam Civiel’s contract was awarded two years ago and has a completion date of 2015. Comprising a 7 km section of the new proposed 18.5 km link from Amsterdam Page 16

South to Duivendrecht, the contract includes laying twin rail tracks both at grade and on seven new elevated bridges alongside the existing rail network. It also includes a station extension at Rai. The new line is intended to form a vital link in public transport plans between Schiphol and Lelystad - doubling the number of passengers each day to almost 80,000 people by 2020. It is planned to double the number of trains from 6 to 12 per hour by 2016 and introduce a ‘travelling without timetable` service. In addition, the new track between Amsterdam South and Utrechtboag will improve the service to Schipol and services, south to Utrecht and beyond.

Stringless Curbs and Gutters Contractor adopts Topcon 3D GPS for its concrete curber By Jeff Winke


ounded in 1932 as a general maintenance and construction company, Summers-Taylor is now the largest, heavy and highway construction contractor serving the tri-state region of Northeast Tennessee, Southwest Virginia and Western North Carolina. Located in Elizabethton, Tenn, the company owns more than 400 pieces of construction equipment and trucks, five concrete plants, and four asphalt plants. Travel an interstate or major highway in this region, it has likely been built or repaired at some point by Summers-Taylor. The family-owned company has grown from its modest start and now employs more than 375. The contractor has diversified, adding design and engineering capabilities to its core construction and paving services. Yet, road building remains at its heart. Not surprisingly, the company is involved with the $18 million Tennessee DOT improvement and expansion of state Highway 75. Just north of Johnson City, the highway spanning between Washington County and Sullivan County is being widened from two to four lanes. The Tennessee Highway 75 project is a four-mile stretch requiring

placement at various locations of concrete curbing and gutters, for drainage and catch basins. “With its long, straight highway run this is the perfect project for us to try our newly acquired 3D GPS machine control on our Gomaco GT-3600 slipform concrete curb and gutter paver,” states Lee Thomson, concrete superintendent for Summers-Taylor. “We’re among the very first, contractors in America running a stringless GPS-based curbing machine—they’re more commonly

a Topcon PZS-I laser sensor—are mounted on the machine to control grade elevation and steering. Because Summers-Taylor uses Topcon Millimeter GPS, which uses laser-enhanced GNSS technology, a pair of Topcon PZL-1 transmitters are positioned at control points on the site. Thompson places the transmitters 500 feet apart to track the position of each receiver on the curb machine and relay curb location and elevation data to the Gomaco curb and gutter machine. As the machine

found in use outside of the States.” Thompson points out that he feels comfortable “pioneering” machine control technology on the curb machine because he’s followed the evolution of the technology over the past 10 years, learned how its benefiting Canadian contractors, and his company is successfully using GPS technology with its earthmoving and site grading side of the business. The Summers-Taylor Gomaco concrete curb machine is equipped with a Topcon GPS+ receiver and an onboard graphical display. A pair of masts—each topped with

progresses, Thompson leap-frogs the transmitters to maintain the slip-form production flow. The PZL-1 Millimeter GPS transmitter uses a fan beam signal that Topcon calls Lazer Zone technology. The PZL-1 is designed to emit a fanned signal with a height of 10 m (approx. 33 feet). Summers-Taylor relied on Construction Engineering Solutions, LLC, Leopold, Ind., to help create the 3D model that was converted via Topcon Office 3D software to the files the curb machine used.

The project requires 1,200 cubic yards or approximately 17,000 linear feet of Class A, 3,000 psi—DOT mix—concrete to form the 30-inch gutters with six-inch high curbs. Summers-Taylor has a six-member concrete crew, including the machine operator. “Since this was our first time using GPS technology on a curb machine, we were nervous at first and began the project by running stringlines in front of the machine,” Thompson says. “The T-DOT inspectors wanted to see the stringlines too, but when we saw the machine could run perfect without them, we stopped placing them. The finished grade is a straight line—no flutter or waves; it is very impressive. Once the T-DOT inspectors saw how good the results were, they pretty much pulled their lower jaws up off their chests and left us with one inspector.” The Highway 75 project is a two-year project and Summers-Taylor is completing its work on time. Thompson reports that

Contractors World - International Vol 5 No 1

adding the millimetre GPS capability to the curbing machine is improving both accuracy and speed, and virtually eliminating rework. “In terms of accuracy, we’re accustomed to achieving the already tight +/-0.1’ finish grade specifications with our Topcon 3D-MC2 earthmoving equipment, so achieving even tighter DOT specs using our Millimeter GPS, with laser-enhanced GNSS technology on our concrete paving work, is more than possible,” says Thompson. “In fact, our curb machine operator comes from the dirt side so he’s comfortable with machine control technology and achieving quality results.” Summers-Taylor is seeing faster production with the GPS machine control on its Gomaco GT-3600 curb and gutter paver. “Clearly, we’re saving time and cost by not needing workers setting stringlines or needing to replace them if they’re knocked down,” Thompson states. “When you consider quicker speed, greater accuracy, and reduction of rework, we’re at least 20 to 25 percent more productive with the stringless GPS curb machine.” In taking in the state Highway 75 project as a whole, Thompson concludes: “I’ll remember this project as our first stringless curb and gutter project.

safe access between the tunnels in the unlikely event of an incident. These were created using several Atlas Copco hydraulic breakers. A Dynapac SD2500CS paver with new V6000TVH (high compaction) screed from Stanley MacAdam, played a major role in the process of laying the 26,000 t of 200 mm compacted, cement treated road base material throughout the entire length of the two tunnels. After setting up the machine to 6.4 m working width and making some fine adjustment on the screed, the machine guided with a Trimble 3D levelling system achieved excellent results with a tolerance of +/-5 millimetres and average compaction density of 89% (modified proctor) before rolling. The material for the paver was supplied through two conveyor belts, which were supplying the mix from the

nearby Mount Coo-Tha Quarry through the entire length of each of the two tunnel tubes. A material chute was placed above several sections of the conveyor belts to drop the mix directly into the back of the trucks used to feed the paver. All this contributed to the paving job finishing two weeks ahead of schedule. TBM Annabell Completes Her Tunnelling Journey Transcity used two Herrenknecht DoubleShield TBMs to excavate Legacy Way’s twin 4.6 km tunnels. These machines each measure 12.4 metres in diameter,

Described as an absolute clean cut, the breakthrough was an impressive sight with the rock wall falling from the top of the TBM. Transcity Project Director, Fernando Fajardo said it was one of the most exciting TBM breakthroughs he had ever witnessed. “It was certainly impressive to see, the wall fell from the top, so it was much more spectacular and exciting for everyone watching,” he said. “The breakthrough of Annabell in such a short time-frame is an amazing feat, and a credit to the team’s combined expertise and hard work,” he said. Launched from the western worksite at Toowong in August 2012, Annabell joined her sister TBM, Joyce, in setting new industry benchmarks as both machines excavated

from Toowong to Kelvin Grove. During her time tunnelling under Brisbane’s inner western suburbs, Annabell achieved incredible records excavating 48 m in one day, as well as a maximum of 239.9 m in one week and a 30 day maximum of 818.89 m. “Our tunnelling performance can be attributed to our seamless logistics process, innovations in tunnel construction, and perfect ground conditions,” Mr Fajardo said. Now she has arrived at the eastern worksite, Annabell will be disassembled beneath the eastern cut and cover structure over the next four months.

Tough Mountain Job for Water Supply Rainfall is a constant source of worry for the water supply cooperative “Kornberggruppe Eislingen” in Germany. When the rain is heavy the seventy-year-old cast iron potable water transport pipeline, running through a canyon called “Teufelsloch” (Devil’s hole) in the neighbourhood of the highway A8 near Bad Boll, is in danger of being jetted free by torrential downpour and torn apart at any time.


everal times it has already been necessary to labouriously repair the pipeline that runs through an inaccessible nature reserve. In an attempt to protect the water pipeline and to counteract erosion caused by heavy downpour, ravine dams were installed to regulate the run-off of the surface water and to prevent further soil Jurassic rock formations in the Swabian Alps are a challenge for any drill rig.

It is precisely this variation in the rock which presented an enormous challenge for HDD bores because the drilling tools must adapt to the varying hardness. A bore hole diameter of 450 mm was required after the final reaming stage. After a series of discussions and careful weighing up of arguments, the cooperative decided to invite tenders for the fluid-assisted HDD method. Decisive factors were not the geology alone but also environmental considerations. To be on the safe side, the assessed installation time was three months, but the drilling crew was able to clear the jobsite after only eight weeks.

The new bore path was planned to run parallel with the old one. After an approximately 100 m long, relatively flat course, the bore path drops away abruptly from 585 m in height to 500 m. Then, after overcoming the hollow, it rises again to 570 m. Decline or ascent sometimes reaches up to 50 %. The complete bore length was 860 m. The bore path was split into three sections: on the right and left side of the valley 200 m and 210 m respectively, with a bore length of 450 m in-between. Specially selected as a new pipe was SLM pipe OD 288 from Egeplast. The multilayer pipe consists of an extremely abrasion resistant, mineral filled polypropylene. This hard casing holds off direct loads from the pressure-bearing pipe and evenly distributes the additional tension caused by sharpedged rocks. Two hundred pipe lengths were delivered as off-the-rack goods, each one 12 m long. These were welded together to form a pipe string on the site of a forest road. The maximum possible tensile load of the pipe is 160 kN and must not be exceeded. The contract was granted to the company WMZ from Wittislingen by the Danube. WMZ uses Tracto-Technik drill rigs exclusively and has completed many demanding drilling projects Work Began in Summer 2013 The project commenced in the 2nd half of July 2013. The Grundodrill 18ACS rock drill rig was used for the complicated job. First of all, the two sections on the right and left side of the valley were installed. Then the 450 m long connecting bore could start. It was an all-time record for the Grundodrill 18ACS. Not only because of the bore length but also because of the bore diameter, the

After that, the time-consuming reaming operations upsizing to 12”, 14”, 16” and 18” started; sometimes, reaming one drill stem length took up to 40 minutes, sometimes only 4 minutes, according to Michael Miklikowski, co-owner of WMZ. Final Act Laying out the pipe string and inserting it in the bore hole had to be conducted very gently to preserve flora and fauna. Thus it was more time-consuming than the pipe pulling itself. Although the pipe had a dead weight of 15 t, the maximum pulling force required was only 60 – 80 kN. The tensile load was not allowed to exceed 160 kN, the complete process was monitored and logged using the GRUNDOLOG tensile load measuring system. Afterwards, the access road, specially laid out for the project before starting with the drill works, was partially worked back to allow rapid regeneration after the minimally invasive intervention in nature.

Rocky Road Ahead Routing with Wirtgen Surface Miners have the solution

Page 28

Contractors World - International Vol 5 No 1

When developing the Chisholm Trail Parkway in the US State of Texas, Wirtgen surface miners are used for routing work and reliably bite their way through hard rock.


he sight on a federal highway in Fort Worth, Texas, is certainly unusual: instead of the road building machines that normally dominate the scene, three mining machines are biting their way through the rocky ground. These machines, however, are not mining pay minerals – they are cutting a route, another domain of the surface miners from Wirtgen. The North Texas Tollway Authority (NTTA) is building the 45 km (28 mile) long Chisholm Trail Parkway here, a toll road which will in future connect Interstate 30 south of Fort Worth with the U.S. Highway 67 near Cleburne. The challenge: routing without drilling and blasting The NTTA faced two problems when planning the project. For one thing, the planned route

ran through exceedingly rocky terrain comprising solid limestone. The other problem was that conventional drilling and blasting methods were not permitted for this project. “We are working inside the city limits of Fort Worth. Drilling and blasting are a thing of the past there and in the nearer environs,” says Mike Manley, Equipment Division Manager, Mario Sinacola & Sons Excavating Inc. The company contracted to undertake the work, one of the largest general contractors in northern Texas, soon presented a quick, albeit at first glance somewhat unusual solution: why not use surface miners for road building to remove the extremely hard limestone substrate selectively, rapidly and with millimetre precision? In mining business, Mario Sinacola & Sons have already successfully used the machines to mine pay minerals for many years, for Wirtgen surface miners cut, crush and load the material in a single operation. Additional machines are not needed; this considerably The clean surface after routing meant highway trucjs could drive alongside while being loaded.

reduces the equipment, personnel and time required. Mining, or routing operations as in Fort Worth, can be undertaken more cost-effectively. An exceptional solution “The earth works cover a vast area, the amount of rock to be removed is relatively large and the work very intensive,” explains Chris Logan, Project Manager, Mario Sinacola & Sons. This is also clear from the following figures: 2.14 million cubic meters of limestone with an average hardness of between 6,000 and 10,000 PSI, including some areas with up to 16,000 PSI. “The surface miners are decisive, especially when the dozers come up against their capacity limits. With the help of the surface miners, we can crush the hard rock to the desired grain size and use it directly in situ,” adds Logan. The company‘s Project Administrator, Channing D. Santiago, adds: “Without the surface miners from Wirtgen, we would instead have to use pneumatic drills for months on end and incur high costs in the process. Surface miners are the ideal choice for this application.”

the profile of the terrain,” says Robert Bauer, the man responsible for the Mining Division at the Wirtgen Group‘s branch Wirtgen America. The unique cutting technology minimizes wear on the cutting tools, even in hard abrasive material, while simultaneously maintaining a consistently high extraction performance. The planned bottom profile is neatly cut at the predetermined depth; forming an ideal sub-base for the paving courses. Transport trucks can drive over the level surface without causing damage during the entire construction period. In Fort Worth, part of the reclaimed material is reused as a lower base course at a depth of 200 mm. On completion, the three-lane road will comprise a 100 mm thick upper base course in addition to the substructure, and a 330 mm thick fully reinforced concrete pavement.

High quality combined with maximum cost-effectiveness While the surface miner 2500 SM with 794 kW (1,065 HP) and a cutting depth of up to 600 mm cuts metre after metre of the main corridor, the two surface miners 2200 SM with a turning radius of just 2.5 m demonstrate their prowess when routing narrower sections, such as ramps and crossings. “By combining Wirtgen‘s standard grade and slope control system for simple adjustment of the precise cutting depth with an More information additional GPS-based system, the operator >>> Wirtgen Surface Miners can optimally adapt the cutting process to >>> Mario Sinacola & Sons Page 30

Hotel Mélia, La Défense, Paris For the Hotel Mélia in the “La Defense” office district just outside Paris, Peri has developed a climbing formwork solution that not only provides complete enclosure of the structure but also serves as erection support for the precast parapets. Due to the spectacular design of this 4-star hotel – inspired by the shape of a ship’s bow – the Peri solution, which is based on the RCS system, has been adapted to meet to a wide range of geometric as well as structural requirements.


he Hotel Mélia is under construction in what is an exposed location, directly at the entrance to the “La Défense” business sector overlooking the Arc de Triomphe and the Champs-Elysées. With 20 upper and 5 basement levels, it will reach a total height of 87 m after completion in 2014. Due to the confined conditions on the construction site, crane time for the formworking operations was to be minimized; in addition, unobstructed and safe pedestrian Contractors World - International Vol 5 No 1

access for the entire construction period have to be guaranteed. The basis for the climbing formwork solution is the flexible Peri RCS rail climbing system whose system components can be used for different applications. For the various areas of the Hotel Mélia structure, Peri engineers developed four different protection panel concepts with specially adapted platforms that met the requirements that ensured safe and rapid construction progress. One particular challenge Page 31

was the design of the forward and reverseangled protection panels for the archshaped facade. For the south-facing facade, the protective panel solution also serves the erection of the precast parapets in advance. Here, the RCS rail is held in position on the parapets of the two lower floors by means of a special mounting and additionally anchored to the floor slabs.

Modern City Development The “La Défense” office district at the gates of Paris was created back in 1966. The business quarter is an extension of the so-called historical axis of the French capital – consisting of the Louvre, Place de la Concorde, Champs-Elysees and Arc de Triomphe. Currently, “La Défense” has 3 million square metres of office space and around 1,500 companies are located here.

The “La Défense 2015” planning for the office district at the entrance to Paris includes a range of refurbishment projects and new buildings. Examples are the Hotel Mélia (foreground) and the Tour Majunga (in the background), whose cores are being formed with ACS self-climbing formwork.

The prefabricated member of the upper floor can then be temporarily fixed in the mounting position using a system component of the Peri FTF facade formwork. The overall concept from Peri included not only the climbing formwork solution but also the planning and delivery of the shoring as well as the slab formwork. Depending on the storey height and loads to be transferred, PEP and Multiprop slab props along with the Peri Up modular scaffold are being used.

Page 32

With the long-term plan “La Défense 2015”, 850,000 square metres of new office space will be created – on the one hand, through the release of new building land and, on the other, through the demolition of existing buildings. In addition, several office towers will be completely modernized. More information >>> Peri Formwork

What’s New in Plant & Equipment Caterpillar Rolls Out New Wheel Loaders The new Cat 980M and 982M Wheel Loaders have EU Stage IV ACERT engines equipped with a combination of proven electronic, fuel, air and after-treatment components. New Cat 982M The new all-purpose 982M benefits from enhanced drive train, reinforced frames and a longer linkage with payloads ranging from 9.0 t in shot rock to 11.4 t in aggregate applications. It is a perfect match for loading the largest European on-highway trucks in quarry yards, small rigid trucks in quarry pits and large articulated trucks on construction sites. The 980M and 982M powertrains both have lock-up clutch torque converters standard, have been matched with the engine power and hydraulics to improve performance and fuel efficiency. These rugged planetary transmissions have a new split-flow oil system and use new multi-viscosity oil to improve fuel economy. The 982M comes standard with the heavy duty 17� planetary transmission. Further axle and hydraulic improvements result in up to 10 percent lower fuel consumption compared to the 980K.

They also have new external calliper disc parking brakes mounted to the input shaft of the front axles. Clipper parking brakes have higher capacity than the drum brakes used on the 980K. The results are reduced fuel and maintenance costs. External calliper parking brakes are easily accessible for inspection and service. The 980M and 982M hydraulic systems also have significant design changes. The main hydraulic valve is now a mono-block with an integrated ride control section. The mono-block design reduces weight, has 40 percent fewer leak points and is common across all M Series models. The new ride control system now has two accumulators, which enables it to be more effective over a greater payload range, increasing productivity and operator efficiency. The 982M has larger lift and tilt cylinders than the 980M due to the new longer lift arm and for the larger payloads it is designed to handle.

What’s New in Plant & Equipment Hydraulic system components on the 980M and 982M are protected by full flow and kidney-loop filtration. This multilevel design ensures the hydraulic oil is clean and thoroughly protects the rest of the hydraulic system from contamination. A new thermal bypass valve has been added to improve hydraulic system warm-up. Operator Efficiency Ensuring operators are safe, confident in control of their machines and have clean, comfortable and quiet operating environments with controls that are intuitive and low effort, all contribute to lower operator fatigue and better performance. A switch has been added to the electronic service center for unlatching the door remotely. The gas strut then swings the door open all while the operator is safely on the ground.

The PC170LC-10 does not have a scheduled replacement interval for its Komatsu Diesel Oxidation Catalyst (KDOC). The KDOC integrated design allows this simple system to remove soot using 100% “true passive regeneration” without the need for a Diesel Particulate Filter (DPF). Lower Owner and Operating Costs The Powerful EPA Tier 4 Interim and EU Stage 3B Emission Certified Engine built on Komatsu’s proven Tier 3 technology, the SAA4D107E-2 engine provides lower emissions and lowers fuel consumption. The Komatsu Tier 4 Interim engine uses an advanced electronic control system to better manage air-flow rate, fuel injection, combustion and exhaust after-treatment to optimize performance, reduce emissions, reduce fuel consumption and provide advanced diagnostic capability. Ease-of-Use for Operators The cab of the PC170LC-10 has a high-resolution 7” LCD colour monitor that displays information in 25 languages for global support. The operator can easily select from six working modes of operation to match machine performance to the application. These working modes include Power Mode, Economy Mode, Heavy Lift Mode, Breaker Mode, Attachment Economy and Attachment Power. The new monitor panel also provides Eco Guidance (operational efficiency guidance), operational records, fuel consumption history, and utilization information. More information >>> Komatsu America

What’s New in Plant & Equipment Liebherr Truck-Mounted Concrete Pump 37 R4 XXT The new truck-mounted concrete pump 37 R4 XXT will be unveiled by Liebherr at the World of Concrete event running in Las Vegas, USA from the 21st to the 24th of January, 2014. Comprising a pump type THP 140 H, this equipment also features a Liebherr-patented XXT narrow outrigger. The four-section, roll-fold distributor boom has a reach of 37 m (121‘-5“) and is extremely torsional-resistant. This ensures reduced vibrations when manoeuvring the boom during onsite applications. Well-balanced weight distribution is achieved by channelling the concrete line extremely close to the boom on both left and right-hand sides. Pressure loss is reduced over the entire length of the distributor boom due to the generous 275 mm (10.8“) radius of the pipe bends. Moreover, the pipe bends are predominantly of the same type, minimising the need to stock diverse replacement parts. Numerous design-related features optimise servicing tasks by simplifying the replacement of wear parts. Liebherr is sole market provider of the exceptionally sturdy and low-torsion patented XXT-narrow outrigger. The front and rear support arms are secured directly to the pedestal of the distributor boom, through which the forces are channelled directly into the supports, completely bypassing the boom. All four support arms are pivot-mounted Page 48

to allow maximum flexibility and a particularly extensive working range of the distributor boom with narrow support configurations. This feature is invaluable on construction sites with restricted access. The truck-mounted concrete pump 37 R4 XXT can be equipped with high-performance pump units featuring three different outputs ranging from 125 m³/h (163 yd³/h) to 163 m³/h (213 yd³/h), depending on the respective application. Chassis from various manufacturers can be used for the truck-mounted concrete pump in accordance with customer requirements. A wide range of optional accessories and equipment are available for the 37 R4 XXT. Contractors World - International Vol 5 No 1

What’s New in Plant & Equipment It is therefore possible for the customer to specify additional storage compartments, an extra diesel tank or a further access point on the left-hand side for example.

redesigned so that the diesel engine is installed transversely, which is a unique configuration in this class. This gives the machine an even more compact layout, and makes all of the principal maintenance points accessible from ground level. The panoramic windshield makes for excellent all-round visibility. Innovations for greater productivity on the new large wheel loaders For the Tier 4i / stage IIIB generation, Liebherr continues to use hydrostatic drive concept together with the Liebherr Power Efficiency (LPE). This is an electronic control system that increases the machine’s handling power and keeps fuel consumption to a minimum. The new-generation diesel engines are now even more environmentally friendly, with many other improvements, too: precision common-rail fuel injection optimizes the combustion process and reduces CO2 emissions. Exhaust emission control is by means of a diesel oxidation catalytic converter combined with a diesel particulate filter. In most situations, this filter can be actively regenerated by burning off deposits during operation of the machine, and the task in hand continued without interruption.

The new generation of Liebherr Wheel Loaders will be presented at the 2014 World of Concrete show in Las Vegas (USA). The L556 model on display belongs to the large-size range of Liebherr wheel loaders and complies with Tier 4i / stage IIIB emission standards. These new-generation machines have an optimized tipping load that further improves productivity and stability. The L 556 with Z-bar linkage for standard operations on display achieves a tipping load of 29,870 lb (13,550 kg) at an operating weight of 39,460 lb (17,900 kg).

Major investment in China’s transport infrastructure Taking place between November 25 and 28, 2014, in Shanghai is bauma China, the International Trade Fair for Construction Machinery, Building Material Machines, Construction Vehicles and Equipment. Although currently challenging, the market in China still offers significant potential, not least because the state is investing heavily in infrastructure. In the first six months of 2013 the equivalent of $160 billion (RMB 1,346 billion) was invested in China in civil engineering and infrastructure projects. According to the National Bureau of Statistics of China this was an increase of over 21 percent as Contractors World - International Vol 5 No 1

World Construction News compared to the same period in the previous year. The biggest part of this money went into road-building. Bernd Schaaf of Germany Trade & Invest (GTAI), Germany’s economic development agency, reports that “the activities here are increasingly concentrating in the west of the country”. That is precisely in line with the Chinese government’s long-term planning: the aim is to promote economic growth in the hinterland, too, away from the already booming coastal region in the east, in order to reduce the wide disparities between the urban and rural communities. “Huge investment in transport and infrastructure is needed if this is to be achieved,” points out Schaaf. According to the current Five Year Plan (2011 to 2015) up to 65,000 km of new roads are to be built in China by the year 2015. Added to this, in the same period, are 30,000 km of new railway tracks around the country with an accumulated investment volume of RMB 2.8 trillion. Building new airports is also on the agenda: GTAI’s current economic report (dated October 2013) reveals that investment here in the first six months of 2013 has risen in comparison to the same period in 2012 by almost 27 percent, to RMB 53 billion. Despite all these major construction projects, the Chinese construction machinery market is not an easy one, as Sebastian Popp, responsible for the construction equipment and building material machinery section at the VDMA, Germany’s engineering federation, explains . “Up until 2011 the country was experiencing a building boom, as the construction sector of the economy was overheating.” Almost all Chinese construction machinery manufacturers reacted to this with a significant expansion of their capacities. Popp again: “As a result of central government’s measures to cool down the building sector, demand for construction Contractors World - International Vol 5 No 1

machinery fell sharply in 2012. Now the situation is one of significant over-capacities and enormous fleets of recently produced machinery in the market.” For the international manufacturers who are producing in China, overcapacity, according to the VDMA expert, is generally not such a problem. The bigger challenge, he believes, lies in resisting over-engineering: “In an ever more competitive market, it’s all the more important to deliver machinery and plant that is attuned to Chinese demand.” Opportunities in this market can be found in particular in high-spec infrastructure projects, says the GTAI expert Schaaf, “For example, in the shape of tunnel-driving machines for above-ground and underground railway construction and special machinery for mining, building construction and civil engineering.” Bauma China 2014

Eyes already on bc India 2014 Opportunities in India continued to grow. In terms of the types of machinery sold most, top of the list in India for many years now have been backhoe loaders, bulldozers and mobile cranes.

Each of these two types of machine is expected to account for a good third of the Indian construction machinery market in 2016. Many suppliers in this sector will gather at bC India in 2014. The last event in February 2013 in Mumbai attracted a total of 710 companies from 33 countries and more than 28,000 trade visitors. bc India Page 56
