Heavy Construction News – Drones provide new perspective for construction


When PCL Construction needed to assess the condition of an Edmonton rooftop in mid-winter, they chose an alternative approach. “Instead of sending somebody up there to walk on the roof in icy conditions, we flew a UAV (unmanned aerial vehicle) over the roof and sent the video to the consultant,” says Mirra Maheden, senior virtual construction specialist for PCL. The video provided the necessary overview, and also allowed the consultant to zoom in on various details in order to complete the assessment.

UAV or drone adoption is one of the fastest growing uses of technology in construction, and inspecting icy rooftops is only one of many emerging applications leading to safer jobsites, better dissemination of information, and in some cases, precise measurement.

Heavy Construction News – Graphene electrodes offer new functionalities in molecular electronic nanodevices — ScienceDaily

Heavy Construction Photos


An international team of researchers led by the University of Bern and the National Physical Laboratory (NPL) has revealed a new way to tune the functionality of next-generation molecular electronic devices using graphene. The results could be exploited to develop smaller, higher-performance devices for use in a range of applications including molecular sensing, flexible electronics, and energy conversion and storage, as well as robust measurement setups for resistance standards.

The field of nanoscale molecular electronics aims to exploit individual molecules as the building blocks for electronic devices, to improve functionality and enable developers to achieve an unprecedented level of device miniaturization and control. The main obstacle hindering progress in this field is the absence of stable contacts between the molecules and metals used that can both operate at room temperature and provide reproducible results. Graphene possesses not only excellent mechanical stability, but also exceptionally high electronic and thermal conductive properties, making the emerging 2D material very attractive for a range of possible applications in molecular electronics.

A team of experimentalists from the University of Bern and theoreticians from NPL (UK) and the University of the Basque Country (UPV/EHU, Spain), with the help of collaborators from Chuo University (Japan), have demonstrated the stability of multi-layer graphene-based molecular electronic devices down to the single molecule limit. The findings, reported in the journal Science Advances, represent a major step change in the development of graphene-based molecular electronics, with the reproducible properties of covalent contacts between molecules and graphene (even at room temperature) overcoming the limitations of current state-of-the-art technologies based on coinage metals.

Connecting single molecules

Adsorption of specific molecules on graphene-based electronic devices allows device functionality to be tuned, mainly by modifying its electrical resistance. However, it is difficult to relate overall device properties to the properties of the individual molecules adsorbed, since averaged quantities cannot identify possibly large variations across the graphene’s surface.

Dr Alexander Rudnev and Dr Veerabhadrarao Kaliginedi, from the Department of Chemistry and Biochemistry at the University of Bern, performed measurements of the electric current flowing though single molecules attached to graphite or multi-layered graphene electrodes using a unique low-noise experimental technique, which allowed them to resolve these molecule-to-molecule variations. Guided by the theoretical calculations of Dr Ivan Rungger (NPL) and Dr Andrea Droghetti (UPV/EHU), they demonstrated that variations on the graphite surface are very small and that the nature of the chemical contact of a molecule to the top graphene layer dictates the functionality of single-molecule electronic devices.

“We find that by carefully designing the chemical contact of molecules to graphene-based materials, we can tune their functionality,” said Dr Rungger. “Our single-molecule diodes showed that the rectification direction of electric current can be indeed switched by changing the nature of chemical contact of each molecule,” added Dr Rudnev.

“We are confident that our findings represent a significant step towards the practical exploitation of molecular electronic devices, and we expect a significant change in the research field direction following our path of room-temperature stable chemical bonding,” summarized Dr Kaliginedi. The findings will also help researchers working in electro-catalysis and energy conversion research design graphene/molecule interfaces in their experimental systems to improve the efficiency of the catalyst or device.

Antonov AN-124-100

"The AN-124-100 commercial aircraft has been developed on the basis of the AN-124 “Ruslan” heavy military transport aircraft. It is the biggest series heavy lifter in the world. It is intended for the transportation of heavy and oversized cargo and various special-purpose vehicles."

"The AN-124-100 has a double-deck fuselage layout. On the upper deck, there is the cockpit and relief crew compartment and the cargo attendants’ cabin. The lower deck is a pressurized cargo compartment. The construction and dimensions of the forward and rear cargo doors, closed with ramps, ensure quick and easy loading/unloading operations. The onboard ceiling mounted cranes allow loading/unloading without ground equipment. The multi-wheel landing gear with rough-field capability, two APUs and mechanized loading enable independent operation of the aircraft from poorly equipped airfields."

AVELING-BARFORD
Grantham & District, Lincolnshire, UK. 1960s & 70s

A large collection of out-takes and unused material originally shot for publicity purposes, much of it filmed during the firm’s last major expansion which occurred, ironically, only a year or two before its effective demise. Originally famed for their road rollers, Aveling Barford also produced a wide range of other civil engineering plant. For convenience and various technical reasons the material has been organised into four sections:

Part One: (1978) Scenes (interior and exterior) at the Grantham factory. These give a good general impression of a wide range of heavy engineering processes — a hydraulic forging press, drilling, boring, and fly-cutting machines, gear cutting, computer-aided design, and final assembly. The overall size of the Works is emphasised by some effective general views. [33 minutes]

Part Two: (early to mid 1970s) The Super 500 Grader in use for motorway construction and at other typical sites, (not all in Lincolnshire) with emphasis on its versatility and ability to cope with difficult terrain. [25 minutes]

Part Three: (early to mid 1970s) Tractor Shovels of two sizes are seen working with a range of different materials at a variety of sites (not all in Lincolnshire). With a grab in place of the bucket, the tractor shovel also handles felled tree trunks. [26 minutes]

Part Four: (early 1960s) Miscellaneous
a) Scenes at a large quarry (location unknown) with dumper trucks, mechanical shovels and tractor shovels. A large rock crushing plant is shown in considerable detail, and a small batching plant is also seen.
b) Miniature tractor shovels marketed as ‘Calfdozers’ are shown moving broken glass or slate, and a modified fork lift truck fitted with special grabs is at work in a timber yard.
c) A Super 500 Grader modified for use as a snow plough grapples with huge drifts in Norway. [26 minutes]

Glencore outbids Yancoal for Rio Tinto’s Hunter Valley coal mines | Reuters – News

Heavy Construction Photos


By Barbara Lewis and Sanjeeban Sarkar

Miner-trader Glencore (GLEN.L) on Friday said it had offered $2.55 billion cash for coal mines owned by Rio Tinto (RIO.L) (RIO.AX) in Hunter Valley, Australia, outbidding a previous offer from Chinese-owned Yancoal.

The large-scale, long-life assets are next to mines already owned by Glencore, which has predicted continued demand for coal, especially in Asia, despite environmental opposition to the most polluting form of fossil fuel.

In January, Rio said it was selling its interest in Coal & Allied Industries Limited (C&A) to Yancoal Australia Limited (YAL.AX) for $2.45 billion.

The terms allowed Rio to engage in negotiations with another party if it made a better offer.

Glencore’s proposal is $100 million higher and fully funded, but Rio Tinto has to give Yancoal the chance to make a counter offer, opening the way for a bidding war.

Rio said in a statement it had received the offer and would respond “in due course”.

Analysts say Glencore has long been interested in the assets and predicted its offer could succeed.

“We cannot see Rio refusing unless it feels it will hurt its cosy China relationships,” Hunter Hillcoat of Investec said.

Glencore’s bid, made up of $2.05 billion upfront and $0.5 billion in instalments over five years, will automatically expire on June 26 if a binding sales agreement has not been reached.

If the deal is completed, Glencore is also offering to buy minority stakes in Hunter Valley operations from Mitsubishi for $920 million cash.

Glencore also said it will stick to a pledge to limit its net debt to EBITDA (earnings before interest, tax, depreciation and amortisation) to a maximum of 2:1.

It would therefore sell assets worth $1.5 billion, possibly including up to 50 percent of its stake in the C&A mines, it said.

Following a deal, Glencore’s combined portfolio would have production capacity of 81 million tonnes per year of high-energy coal, which would meet Asian demand, Glencore said, adding it already had regulatory approval from the Japanese anti-trust authorities.

Coal asset sales stalled last year when coal prices hit nearly five-year highs and miners raised their expectations on bids for their assets.

Agreeing deals has also been complicated by climate change concerns and shareholders have questioned the long-term financial sustainability of mining portfolios.

Glencore says it reviews the sustainability of its assets and has said it sees continued demand for high-quality coal that can still be the cheapest form of baseload power.

Japan has been forced to burn more coal following the Fukushima disaster, which led to the shut down of nuclear capacity.

David Neuhauser, managing director at U.S. hedge fund Livermore Partners, which owns Glencore shares, said the offer was strategic.

“In the past, they tried to gain producing assets at any cost. Today they’re targeting deals that are very prudent, opportunistic and move the needle in terms of their cash flow,” he said.

Washington State News | Seattle mayor touts construction milestone


Seattle Mayor Ed Murray says completing a tunnel that will serve as an underground highway was “a major construction milestone in our plan to reclaim Seattle’s waterfront.”

Murray said Tuesday that the city is one step closer to taking down a double-layer waterfront highway to make room for “our vision of a well-connected 21st century city” serving “pedestrians, transit and sensible car trips.”

Washington Gov. Jay Inslee says the breakthrough is “a historic moment in our state’s transportation history.”

Critics call it an expensive vanity project, and environmentalists have objected to building another highway in Seattle.
