With arising worries about the environment, global warming and pollution, skyscrapers, office towers and even mosques are increasingly incorporating green and eco-friendly design and features. Here, as part of the sustainability week on WCN, we look at some of the world’s greenest buildings.One Angel Square, UK
‘Living walls’, green façades, vertical farming or roof gardens are increasingly featuring in the design-concept of buildings.
The International Organisation for Standardization (ISO) has laid down the design principles to create earthquake-resistant cranes. The new ISO 11031 can be used to calculate seismic loads, and sets out the design principles for cranes destined to work in seismically-active regions and for cranes required to be seismically-resistant.Klaus Pokorny, secretary of the ISO subcommittee working on design principles and requirements for cranes, said: “To make sure that cranes are safe, we first need to calculate the seismic loads that show how a crane will respond in moderate to severe earthquakes. Then you can use design limit states provided in two forms: serviceability limit and ultimate limit. “The serviceability limit state (SLS) ensures that the crane can withstand the effects of moderate earthquake ground motions throughout its service lifetime and continue to operate as intended. The ultimate limit state (ULS) requires that the crane structure should not collapse during severe earthquake ground motions, and that the suspended load or any other part of the crane should not fall or harm the public, operators and workers.” Pokorny added: “Any evaluation should take into account the regional seismic conditions as well as the ground surface conditions at the crane location. It’s also important to consider how the crane will be used and any risks that could result from seismic damage.“Not only will ISO 11031 add a layer of confidence to the industry, it also provides a common technical language so that manufacturers, users and owners understand each other clearly, no matter where they are — a boost for global trade.” The need of a standard to ensure seismic-resistant cranes was first highlighted by Japan, after the 1995 earthquake in Kobe.
Recycling has never been more popular, with people encouraged to set aside paper, food, glass, plastic and more. But what about recycling our roads? Roads deteriorate over time, and rehabilitating works have to be carried out regularly — road signs warning about roadworks are a common sight. To make this rehabilitation more efficient, a time-saving and new environmentally-friendly technology has been introduced into the UK this year — having already been widely established in North America, Europe and China. The cold recycling technology involves the milling and granulation of damaged asphalt layers, which are then rebound, placed again and compacted. The cold recyclers — the machinery used in the process — recycle the underlying layers of the road. The old surface material is churned up with new binder in the machine’s mixing-chamber, before laying down the new, recycled mix immediately on the road behind. Mike Reay, managing director at Lane Rental Services which owns and operates the first UK cold recycler, says: “The recycling layer is the layer beneath the surface. Following the recycling a brand new surface course is installed — first a new structural re-strengthen layer is provided by the recycler and then a brand new layer, running surface, is provided straight after that’s been completed.”The cold recycler when operating in the project’s site needs the assistance of a second machine in order to complete the resurfacing work. “A final surfacing, after the recycling process, is always done with an asphalt paver,” says Martin Diekmann, Wirtgen’s recycling product manager. “This means that an average 4cm hot mix asphalt layer as a wearing course is paved on top of the recycled layer.”Wirtgen — the market leader in cold recycling technology — has sold 1,000 cold recycler machines worldwide so far, according to Diekmann, and this number is expected to grow.The cold recyclers can be used for thin asphalt layers or minor roads, as well as for thick asphalt or heavily-trafficked motorways. A UK firstThe first UK cold recycler made its way into the country three months ago. “I was aware of the machinery used in the States and also in Europe. I visited a site near Toulouse in France in 2015 and was impressed with the equipment,” says Reay.He adds: “This equipment has been tried and tested in the USA and Europe, therefore we had the confidence to introduce it to the UK.” The cold recycling technology was first used in the UK on a Highways England project to resurface 1.6km of the A1 at Brownieside in Northumberland. “I discussed it with AOne+ [the project’s contractor] and, obviously mindful of Highways England delivery programme requirements, we jointly decided the time was appropriate for this introduction to the UK. We ordered the machine and some trials schemes were authorised and have now been carried out,” says Reay.The Wirtgen 3200 CR cold recycler is owned and operated by Lane Rental Services and was especially custom-made for the project. Reay adds: “It has been custom-made for the UK market, not only for the 2016 works. It will be the UK machine.” The 3200 CR differs from the standard Wirtgen 2200 CR and 3800 CR on its operating width. While the 3200 CR cuts on a 3.2m width, the other two machines cut at 2.2 and 3.8m widths, respectively.
John Deere has entered into a partnership with HCSS to enhance its construction machinery data communication and analysis system WorkSight.The partnership will also focus on the incorporation of Deere’s JDLink machine monitoring system into HCSS’s software.The partnership was one of the results of the Association of Equipment Management Professionals (AEMP) working with major machine manufacturers to standardise the telematics data available for integration into other applications, known as the Application Programming Interface (API).Liz Quinn, John Deere WorkSight product marketing manager, said: “Our partnership with HCSS empowers customers to leverage the existing telematics connection on their John Deere equipment and see their JDLink machine data in the powerful HCSS tool suite in conjunction with other telematic brands. “In addition, customers will be able to easily link from the HCSS application to the MyJohnDeere.com environment when they need to order parts, manuals, or have a closer look at a John Deere machine in the JDLink Dashboard. Seeing all brands of telematics data in one application optimizes a customer’s fleet management decisions and eliminates manual data entry and jumping from one manufacturer’s portal to the next.”Matthew DiTarando, John Deere customer and IT manager at Comanco Environmental Corporation, said: “We look forward to utilizing the open JDLink Machine Data API and integrating that vital telematics data into our HCSS products. Combining these two into one cohesive system will enable us to thrust our fleet department forward into a future of advanced planning of scheduled maintenance utilizing real-time telematics.”HCSS has been testing the JDLink Machine Data API, which is scheduled to launch later this year.WorkSight incorporates five technologies: the JDLink Telematics, Machine Health Prognostics, Remote Diagnostics and ProgrammingPayload Weighing and Grade Control.
Australia-based company Fastbrick Robotics has developed a giant truck-mounted robot that can construct an entire house in two days. Hadrian X can lay up 1,000 bricks an hour using a 28ft arm. The robot uses 3D scans to work out where to lay down the bricks, which are fed to the machine’s conveyor, then passed along the arm into a laser-guided claw. The claw grabs and lays them down using construction glue instead of cement.The smart machine cuts bricks to size and leaves spaces between them for wiring and plumbing.Fastbrick Robotics’ founder Mark Pivac told Perth Now: "People have been laying bricks for about 6,000 years and ever since the industrial revolution, they have tried to automate the bricklaying process."We're at a technological nexus where a few different technologies have got to the level where it's now possible to do it, and that's what we've done."It is estimated that the robot can build between 100-300 houses a year — without needing tea breaks, holidays or weekends off.Hadrian X took ten years to be developed and $4.5M in research and development. According to Fastbrick Robotics, it will take about a year before the machine will be launched onto the market.
What links novelty personalised figurines, prosthetic body parts, components for cars and fighter jets, jewellery, guitars — and now, houses?They’re all on the list of objects that have been created using 3D printing technology. And while some of those projects will probably prove to be passing fads — feel free to take a moment at this stage to Google the inexplicable Japanese trend of printing models of Hollywood actor Keanu Reeves looking sad, if you really must — the use of 3D printing to produce entire buildings is gathering momentum.A few years ago, 3D printing or additive manufacturing (AM) was used in the construction sector mainly to produce construction components and niche parts, such as interior-decorating features, lighting effects and furniture. In recent years construction companies and national governments raised the bar with ambitious projects to 3D-print bigger and bigger structures. The goal was set: 3D print entire buildings. The challenge was laid down and the industry could only wait for the first buildings to rise. And they did. In several countries 3D-printed projects have been initiated, and in some they have now been finished. That is the case in Dubai, where the world’s first 3D-printed office building has recently opened its doors. The 250sq m single-storey building has been built in just 17 days using a 20ft tall 3D printer and a special mix of concrete — fibre-reinforced plastic and glass fibre-reinforced gypsum. The gigantic printer was 120ft long and 40ft wide and ‘worked’ almost alone, as it only needed one staffer to make sure it was functioning properly. The rest of the 18-person construction crew consisted of installers, electricians and mechanical engineers who completed the project for just a mere $140,000 in construction and labour costs, about half price of a comparable structure built using conventional methods. The building is set to have a practical use as the temporary headquarters for the Dubai Future Foundation, becoming home of Dubai’s Museum of the Future next year. The opening follows the launch of the ‘Dubai 3D Printing Strategy’ and the forecast that a quarter of buildings in Dubai will have 3D-printed elements by 2030.
Otis Elevator Company has introduced the new SkyBuild self-climbing construction elevator.According to the company, the SkyBuild elevator — part of the SkyRise family — enables builders to complete high-rise projects faster, while reducing costs. It is designed to be sustainable and to reduce space requirements and energy.Installed at the beginning of a building’s construction, the elevator’s hydraulic piston system enables it to climb a floor at a time as the construction work advances and the building rises, removing the need for a temporary and external lift subject to different weather conditions. This allows movement of crews and tools quickly and safely.Once construction is complete the elevator transitions for immediate service as a SkyRise lift within the building.Bora Gülan, vice president of Global Major Projects and Key Accounts at Otis said: “The Otis SkyRise product family combines a refined passenger experience with state-of-the-art elevator technologies and support our customers can count on. “Our SkyBuild option now offers customers even more value with an elevator system that rises with the building – quickly and easily jumping one floor at a time to meet the requirements and pace of any project.”
Hitachi displayed three new excavators and a wheel loader at Bauma in April. The new ZX19-5 mini excavator, to be used on construction projects, is designed to be user-friendly. According to the manufacturer, the Zaxis-5 model offers high levels of performance, stability and easy maintenance. The boom cylinder, in the new excavator, has been moved on top of the boom to protect from potential damage, making it more efficient when working on narrow spaces, as its front minimum turning radius is smaller. A new folding travel pedal can now be used instead of the hand lever, improving the operation speed. Other improvements include the placing of the hydraulic hose inside the boom and the addition of a new blade, capable of making digging more precisely.There is also more space between the operator and the front window and more legroom in the cab. The cab has a new design that features a large LCD monitor located on the right-hand side, displaying the vital technical data, including the machine’s status and settings and a drinks holder for easy access to refreshments. Security has been improved, with an optional theft deterrent system that requires a four-digit number to unlock before the engine can be switched on.Hitachi also showcased the ZX300LCN-6 super long front medium excavator. The excavator has a six-cylinder 186kw stage IV-compliant engine, with the highest output in its class, and offers 14% higher productivity in PWR mode. Delivering lower fuel costs, the machine was specially designed for earthmoving on dredging, bank maintenance and slope finishing projects. The excavator also features a reconfigured lower roller that ensures mud falls out easily, an expansion tank that cools the engine parts, and enlarged track guards.The tilting rotator and tilting bucket modes are also included within its attachment support system.The new ZX490LCH-6 large excavator was designed to meet the demands of large-scale construction projects, set to offer a high level of durability without compromising efficiency. It features a boom reinforced with thicker plates and an undercarriage consisting of robust components such as track link, master pin, idler pedestal and bracket and upper roller bracket. The large excavator also incorporates an in-cab console, made of weather-resistant AES-grade resin that prevents UV rays damage, and sealant to eliminate any heat deterioration. These ensure the machine’s long-term cooling and low-noise performance.This excavator is able to save up to 5% fuel in eco mode with the same productivity as previous models, due to the use of HIOS IIIB technology. The after-treatment device helps the machine produce fewer emissions and to have a quiet performance. Furthermore, attachments to carry on different tasks can be easily fitted to the versatile machine that uses the attachment replacement support system.Also launched in Munich was the ZW370-6 wheel loader. With enhanced performance and low fuel consumption, the machine employs a new EU Stage IV-compliant engine that does not require a diesel particulate filter, which reduces maintenance costs.The wheel-loader has a 360° panoramic view from the spacious cab and a rear-view camera, visible on the multifunctional LCD monitor. Less noise can be heard within the cab thanks to an improved sound isolation. A smooth operation is ensured by the optional Joystick Steering System, which enables operators to reach high levels of productivity with effortless steering, it is said.There are also two types of lift arm available that customers can choose, depending on the required application.
Man showcased the D38 engine in the TGX series and the new light hypoid tandem axle at Bauma.The combination of the D38 engine with the TGX series is used for heavy-duty traction operation and for the transportation of heavy loads while going at high speeds, with engine power over 500HP.In a construction site, for example, a low loader trailer with heavy construction machines that need to be pulled can be moved up to a gross train weight (GTW) of 120t easily by the TCX D38. The two-stage turbochargers make the six-cylinder in-line engine with 15,256ccm displacement reach a nominal torque of 2700Nm at 930rpm.Also launched in Munich, the new light hypoid tandem axle for payload-sensitive transport tasks has a weight advantage of 180kg, according to the company, when compared with the hypoid axles currently used, meaning that it is possible to transport 180kg more concrete or water. It has a gross combination weight of 60t.With the tandem axle, the fuel used is slightly lower, offering additional ground clearance of about four centimeters, achieving the N3G approval.In addition, the Germany-based mechanical engineering company announced at the trade show an extension to its range of drive configuration in the TGS and TGX series, with the D20 and D26 engines and presented the updates made to its entire TGS and TGX series engine portfolio for IAA 2014.

Especially built for the construction environment, the display produces higher quality outcomes in less time and with less effort.Besides the tablet computer display, other products launched in Munich include the Proactive Monitoring system, which utilises innovative technology that enables Volvo dealers to remotely monitor alarms and fault codes on customers’ machines.These products are part of the new approach developed by Volvo on how to offer services and solutions to customers.
A new truck-mounted concrete pump was presented by Putzmeister at Bauma, which took place in Munich in April.Named BSF 47-5, the new truck features a five-arm placing boom mounted on a four-axle chassis and weighs less than 32t, including the reserves for payload, water, fuel and other functional fluids. It is one of the most lightweight machines in its class, says Putzmeister.The flexible five-arm boom with the roll-Z fold system has excellent slip characteristics; it can be deployed quickly and makes optimal use of the available space, thanks to its new flexible support, a base structure that follows the new I-frame concept. An 800l water tank can be easily attached to it. Vibrations in the boom remain at a low level, achieved through an intelligent laying of the delivery line and a balanced progression of stiffness in the steel structure. The concrete distribution is then safer and more efficient. In addition, the machine operator is provided with an image of the working area live on display of the remote control. The improved S transfer tube bearing, the heart of the machine, has a delivery rate of up to 160m³/h.The Ergonic 2.0 control system, an upgraded version of the Ergonic Boom Control system (EBC) used to control the placing boom, was also presented to the public in the trade show. The truck’s operation costs have been reduced, as its components are highly resistant with some being maintenance-free.
ThyssenKrupp launched its biggest gyratory crusher, which the company says is the world’s largest, at Bauma in April. The German-based engineering, construction and service provider welcomed visitors to the 220sq m booth with numerous 3D models and a virtual stimulation of the brand-new gyratory crusher.The crusher’s throughput can go up to 14,000t/h, 30% higher than the previous version, and has a driving rate of 1,500kw. It is also much lighter than its predecessor, despite being 130 inches in diameter. These changes are expected to increase its performance at a lower weight.Other products shown by ThyssenKrupp at the trade show included the modernized and standardised cone crushers, RollSizers, and the Barracuda and Mine Shark compact bucket wheel excavators.
