Drones possess great potential for the construction industry in particular and a wide variety of benefits have already been demonstrated by the early adopters of this technology. The construction industry is now one of the main drivers of growth across the commercial drone sector.
An ongoing and potentially revolutionary innovation within construction is the growth of modular buildings. Modular buildings are defined as prefabricated structures consisting of multiple sections termed modules. Modular construction differs from traditional forms of construction due to the fact that module sections are completed offsite before being transported to the construction site, where they are then positioned into place.

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.

If you believe the old song, the M25 motorway that circles London is ‘The Road to Hell’. But while many motorists may be inclined to agree with that sentiment — particularly during the coming bank holiday weekend — there are plenty of roads around the globe that offer much more than traffic jams and suspect hotdogs from service stations. From those that take in remarkable natural scenery, through to those constructed using innovative technologies — we look at some of the world’s most interesting roads.1) The Atlantic Ocean Road, Norway
As technologies for road construction advance, so too do the highways that connect cities, countries, and even continents. We look at the seven longest roads in the world today.1) Pan-American Highway, American continent
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.
