This company is trying to create an entire town where every house is equipped with solar shingles. The entire roof of this building will be a solar panel. This is a big leap in LED construction. Things will be self sustaining eventually.

SolarCity doesn't want to just install solar panels on your roof; it wants solar panels to be your roof.

SolarCity thinks it can convince 5 million American households to replace their roofs with solar energy shingles.

Instead of installing panels like these on top of an existing roof, the company is working on "solar shingles" that would replace a home's roof and absorb solar energy.

About 1 million Americans have solar panels on their homes, so adding another 5 million to that list would be quite the accomplishment.

But the company seems to think the solar shingles can fix some of the biggest problems associated with solar energy.

Elon Musk, the company's chairman, says the solar roofing looks better and lasts longer than normal roofing.

And Musk says installing or replacing the solar shingles shouldn't be much different than when using regular roofing materials.

But the company will still need to keep costs down if it wants to see mainstream adoption.

The Dow Chemical Company recently had to discontinue its line of solar shingles because the product wasn't selling - likely because they were more expensive and less efficient than typical solar plants.

But SolarCity isn't talking about price or its energy output yet.

Right now, it's in the middle of a merger with Tesla Motors, which could open up the option to package the solar shingles with Tesla products like the home battery. That could make the adoption process for solar roofing easier and cheaper.

Missouri is looking to be the first state to experiment with solar roadways. It will be interesting to see if this innovation will save money or cost the state in the long run. Will this be too costly to repair and maintain?

TOWN & COUNTRY, MO (KTVI) - Solar panel pavement may be the future of Missouri roads. The Missouri Department of Transportation along with a startup company in Idaho, Solar Roadways are experimenting with the technology that's the first its kind in the country.

MoDOT started the 'Road To Tomorrow Initiative' about a year ago to generate new innovations that have the possibility of creating a new revenue stream for transportation.

One focus is the creation of energy through public roadway.

That's where Solar Roadways comes in.

The company is researching how much energy solar panels can generate laid flat (as they would be on roads) compared to a traditional angled solar panel in Town and Country.

"I am really hopeful that it will succeed. It can create a lot of good things right here in the state of Missouri," said Tom Blair, Road To Tomorrow Initiative Leader with MoDOT.

Blair says the solar roads have the potential to pay for themselves because of the electricity they can generate and turn into revenue.

Not only that, but a heating element can be incorporated into each panel to melt away snow and ice.

Blair says right now, MoDOT spends between $40-$50 million each winter season to plow snow from roads and de-ice.

Before taking the technology to the interstates, MoDOT plans to start small, with a solar sidewalk at a welcome center in Conway, Mo. They expect that $100,000 project paid for by a grant, to be complete before the year's end.

New earthquake resistant pipelines will now make water transportation in California a safer and more reliable source. Pipelines can now withstand the earthquake intense area and not cut off water to thousands of residents during a disaster.

# data[].attributes.attachment_link.readable_text
A top engineer from the city of Los Angeles visited Cornell University this month as researchers tested a new earthquake-resilient pipeline designed to better protect southern California's water utility network from natural disasters. They ran multiple tests, including an earthquake simulation in which a 28-foot-long section of the pipe was outfitted with more than 120 monitoring instruments and buried within 80 tons of soil -- an experiment that took over a month for the research team to prepare.

The test mimicked a fault rupture that can occur during an earthquake when global plates begin to slip past each other, causing the ground to shift and deform. A large, hydraulically powered "split box" imposed 2 feet of fault rupture along a 50-degree angle, forcing the buried pipeline into a combination of compression and bending.

"The pipe was able to accommodate the 2 feet and didn't spring a leak," said Brad Wham, a geotechnical engineering postdoc from Cornell who designed the test, which was performed at the Cornell Geotechnical Lifelines Large-Scale Testing Facility. "We took the pipe to three times its current design standard, and it continued to convey water. So we consider it a successful test and very promising technology." And while the test pipe was only 8 inches in diameter, Wham says the results are scalable and could be applied to pipelines as large as 70 inches in diameter or greater.

"It surpassed expectations," said Tom O'Rourke, professor of civil and environmental engineering at Cornell University and the project's principal investigator.

The steel pipe, developed by JFE Holdings in Japan, uses a unique structural wave design to control buckling, allowing the pipe to bend and compress without rupturing or losing water pressure. The wave features are installed at key locations along the pipeline to absorb large ground deformation, such as movements imposed by earthquakes and landslides or from undermining associated with scour during hurricanes and floods. The extent of its performance was unknown until it arrived at Cornell.

The results are significant for Los Angeles and other West Coast cities that want to upgrade their aging utility systems, especially portions that cross over fault lines. Craig Davis, the resilience program manager for L.A.'s Department of Water and Power, attended the testing and said his city's water utility system -- the nation's largest -- crosses over 30 fault lines en route to supplying water to more than 4 million residents. The new pipe produced by JFE Holdings now gives Davis and other engineers a new option for securing water supply to the city's most vulnerable areas.

Los Angeles is upgrading its water utility system through the "Resilience By Design" program implemented by Mayor Eric Garcetti, and other municipalities around the country are eager to initiate similar programs following natural disasters like Hurricane Katrina and Superstorm Sandy. "What we've actually seen is a paradigm shift in pipeline technology, and it's a market-driven research environment," said O'Rourke, who added that a steady stream of business from manufacturing companies like JFE Holdings has kept his facility in high demand. "All of the West Coast utilities say that if you want us to consider your pipe, you have to test it Cornell. Ours is the only facility in the world that can perform these kinds of tests."

Following the fault rupture test, the research team spent three days carefully excavating the pipeline and will begin collecting additional data based on its deformation. The results will help officials identify the most strategic locations for the new pipeline to be installed.

"We modeled the Los Angeles water supply and have the entire system on a secure computer," said O'Rourke. "We created the next generation of hazard-resilient network modeling, and they actually used it to develop policy and emergency response operations."

Los Angeles is not the only city to benefit from Cornell's unique testing facility. San Francisco has implemented fault rupture hazard solutions for pipelines validated by Cornell, with Portland, Seattle and Vancouver all considering upgrades based on recent test results.

In nature, wood, shells, and other structural materials are lightweight, strong, and tough. Significantly, these materials are made at the ambient temperature in the local environment -- not at the high temperatures at which human-made structural materials are generally processed. Similar materials are difficult to make synthetically. In a review article in Nature Materials, a team of scientists assessed the common design motifs of a range of natural structural materials and determined what it would take to design and fabricate structures that mimic nature. They considered the remaining challenges to include the need for comprehensive characterization of strength and toughness to identify underlying multiscale mechanisms.

This comprehensive assessment provides new inspiration and understanding of design principles that may lead to more efficient synthetic approaches for advanced, lightweight structural materials for transportation, buildings, batteries, and energy conversion.

In the natural world, many of the structural materials (wood, shells, bones, etc.) are hybrid materials made up of simple constituents that are assembled at ambient temperatures and often have remarkable properties. Even though the constituent materials generally have poor intrinsic properties, the superior extrinsic properties of the hybrid materials are the result of the arrangement of hard and soft phases in complex hierarchical architectures, with dimensions spanning from the nanoscale to the macroscale. The resulting materials are lightweight and usually show interesting combinations of strength and toughness, even though these two key structural properties tend to be mutually exclusive. It is relatively easy to make materials that are strong or tough, but difficult to make materials that are both.

The scientists review common design motifs of a range of natural structural materials and lessons learned by understanding how the components of the structure work together to produce materials with superior properties. The authors identified two fundamental challenges in the field of bioinspired materials: (1) approaches to take advantage of nature's design motifs in a wider range of material combinations and (2) practical methods to make strong, tough bulk materials.

Future nature-inspired techniques include advanced additive manufacturing (for example, 3D printing) and casting.

This new innovation to roadways has lead to the creation of precast flexible concrete slabs to make road work 50% faster.

# data[].attributes.attachment_link.readable_text

Nanyang Technological University (NTU Singapore) scientists from the NTU-JTC Industrial Infrastructure Innovation Centre (I³C) have invented a new type of concrete called ConFlexPave that is bendable yet stronger and longer lasting than regular concrete which is heavy, brittle and breaks under tension.

This innovation allows the creation of slim precast pavement slabs for quick installation, thus halving the time needed for road works and new pavements. It is also more sustainable, requiring less maintenance.

NTU Professor Chu Jian, Interim Co-Director of the NTU-JTC I³C, said, "We developed a new type of concrete that can greatly reduce the thickness and weight of precast pavement slabs, hence enabling speedy plug-and-play installation, where new concrete slabs prepared off-site can easily replace worn out ones."

Mr Koh Chwee, Director, Technical Services Division of JTC and Co-Director of the NTU-JTC I3C, said that the invention of this game-changing technology will not only enable the construction industry to reduce labour intensive on-site work, enhance workers' safety and reduce construction time, it also benefits road users by cutting down the inconvenience caused by road resurfacing and construction works.

"Through collaborations with universities such as NTU in research and development of disruptive technologies, JTC hopes to pioneer cutting-edge industrial infrastructure solutions to address challenges faced by Singapore and its companies such as manpower and resource constraints. We will continue to open up more of our buildings and estates to test-bed and if successful, implement such new solutions," Mr Koh added.
How bendable concrete works
Typical concrete comprises cement, water, gravel and sand. While this mixture makes concrete hard and strong, it does not promote flexibility. Thus concrete is brittle and prone to cracks if too much weight is applied.

ConFlexPave is specifically engineered to have certain types of hard materials mixed with polymer microfibres. The inclusion of these special synthetic fibres, besides allowing the concrete to flex and bend under tension, also enhances skid resistance.

The key breakthrough was understanding how the components of the materials interact with one another mechanically on a microscopic level, said Asst Prof Yang En-Hua from NTU's School of Civil and Environmental Engineering who leads this research at the NTU-JTC I³C.

"With detailed understanding, we can then deliberately select ingredients and engineer the tailoring of components, so our final material can fulfill specific requirements needed for road and pavement applications," explained Prof Yang.

"The hard materials give a non-slip surface texture while the microfibres which are thinner than the width of a human hair, distribute the load across the whole slab, resulting in a concrete that is tough as metal and at least twice as strong as conventional concrete under bending," he added.

ConFlexPave has been successfully tested as tablet-sized slabs at NTU laboratories. It will be scaled up for further testing over the next three years in partnership with JTC -- at suitable locations within JTC's industrial estates and in NTU where there will be human and vehicular traffic.

Nature is genius in the ways that it constructs itself and stays strong in disasters. Scientists learned from the structure of coconut palms to hopefully create a new strong system to help prevent earthquake damage.

# data[].attributes.attachment_link.readable_text
Coconuts are renowned for their hard shells, which are vital to ensure their seeds successfully germinate. But the specialised structure of coconut walls could help to design buildings that can withstand earthquakes and other natural disasters.

Coconut palms can grow 30 m high, meaning that when the ripe fruits fall to the ground their walls have to withstand the impact to stop them from splitting open. To protect the internal seed, the coconut has a complex structure of three layers: the outer brown, leathery exocarp, a fibrous mesocarp and a tough inner endocarp surrounding the pulp which contains the developing seedling. As part of a larger project on "Biological Design and Integrative Structures," researchers at the Plant Biomechanics Group of the University of Freiburg have been working with civil engineers and material scientists to investigate how this specialised structure could be applied in architecture.

The researchers used compression machines and an impact pendulum to investigate how coconuts disperse energy. "By analysing the fracture behaviour of the samples and combining this with knowledge about the shell's anatomy gained from microscopy and computed tomography, we aimed to identify mechanically relevant structures for energy absorption" says plant biomechanist Stefanie Schmier.

Their investigations found that within the endocarp layer -- which consists mainly of highly lignified stone cells- the vessels that make up the vascular system have a distinct, ladder-like design, which is thought to help withstand bending forces. Each cell is surrounded by several lignified rings, joined together by parallel bridges. "The endocarp seems to dissipate energy via crack deflection" says Stefanie. "This means that any newly developed cracks created by the impact don't run directly through the hard shell." It is thought that the angle of the vascular bundles helps to "divert" the trajectory of the cracks. The longer a crack has to travel within the endocarp, the more likely it is that it will stop before it reaches the other side.

The distinct angle of the vascular bundles in the endocarp could be applied to the arrangement of textile fibres within functionally graded concrete, to enable crack deflection. "This combination of lightweight structuring with high energy dissipation capacity is of increasing interest to protect buildings against earthquakes, rock fall and other natural or humanmade hazards" says Stefanie.

What does one need to strengthen or toughen concrete? A lot of nothing. Or something.

The "nothing" is in the form of microscopic voids and the "something" consists of particular particles embedded in the most common construction material on Earth. Rice University materials scientist Rouzbeh Shahsavari and postdoctoral researcher Ning Zhang analyzed more than 600 computer models of concrete's inner matrix to determine that both voids and portlandite particles are significant players in giving the material its remarkable qualities.

The research appears this month in the Journal of the Mechanics and Physics of Solids.

Shahsavari and his team set out to provide new insights and to design guidelines and strategies to make the cement hydrate -- known as calcium-silicate-hydrate (C-S-H) -- at the heart of concrete more tunable from the molecules up. They found that while concrete may appear brittle at the macroscale, it incorporates ductile fracture mechanisms at the nanoscale that help to keep it from failing.

"C-S-H is the smallest building block in concrete, and we want to understand and control it to our advantage," Shahsavari said. "Modeling how its molecules interact helps us understand its nanoscale structure, defects and fracture toughness. But this is very difficult to study through experiments alone because of the scale of the features we're looking at."

This latest in a series of studies from the Rice lab looks at how the interaction of either random air voids or random portlandite particles in C-S-H influence the mechanical qualities of strength, stiffness and toughness, especially where voids meet propagating cracks.

"Besides C-S-H, portlandite is another product of cement hydration, but it forms in lower quantities compared with C-S-H and mainly exists as sort of inclusions or isolated islands surrounded by the C-S-H matrix," Shahsavari said. "Because portlandite has different crystalline features and mechanical properties than C-S-H, its presence and distribution can significantly impact the mechanics of C-S-H."

Using molecular dynamics simulations, the researchers found that cracks tended to follow the path of least resistance and turn in the direction of either the nanovoids or portlandite particles they encountered. By deflecting or changing the geometry of a crack, the voids and particles sapped the crack of energy. Shahsavari said this likely contributes to concrete's overall toughness.

"When it comes to cement hydrate's strength and toughness -- properties that are typically exclusive in human-made materials -- random voids and portlandite particles play a key role by regulating a series of competing deformation mechanisms, such as crack growth, crack deflection, voids coalescence, internal necking, accommodation and geometry alteration of voids and particles," Shahsavari said. "Our work decoded all such complex competing mechanisms."

For C-S-H that is more amorphous than crystalline (as in tobermorite concrete), they found the addition of portlandite particles induced strong chemical reactions that increased the strength as well as the toughness of the product. They also determined that for all the variations tested, the smaller the mean diameter of both voids and particles, the stronger the material.

Since more than 30 billion tons of concrete are used each year and its manufacture contributes up to 10 percent of carbon dioxide emissions worldwide, the payoff from any small tweak is worth the effort, Shahsavari said.

"Our results provide, for the first time, new evidence of ductile fracture mechanisms in cement hydrate that are reminiscent of crystalline alloys and ductile metals," Shahsavari said. "Given that crack growth and strength are an inherent property controlled by nanoscale deformation mechanisms, our findings can impact the mechanical properties of concrete at larger scales, opening up new opportunities and strategies to turn brittle cement hydrate into a ductile material. This would impact the modern engineering of durable concrete infrastructures and potentially other complex brittle materials."

A federal judge has granted part of a Native American tribe's emergency request to halt construction of a section of oil pipeline in North Dakota.

The Standing Rock Sioux Tribe fears the pipeline could contaminate its drinking water and sacred lands, as we've reported. U.S. District Judge James E. Boasberg's temporary restraining order is "a mixed victory for both sides," as The Bismarck Tribune wrote.

In the motion filed Sunday, the tribe had sought protection for a larger area along the planned route for the $3.8 billion Dakota Access Pipeline - which is set to span some 1,200 miles, from North Dakota to Illinois.

The area not covered by the judge's order includes lands that the tribe is particularly concerned about protecting. Work in that area, west of State Highway 1806, started over the weekend, according to Prairie Public Broadcasting,

Tuesday's ruling is part of a larger lawsuit filed in July seeking an injunction against the U.S. Army Corps of Engineers, which authorized the pipeline's construction. As we've reported, " the tribe filed a complaint with the United States District Court for the District of Columbia, arguing that the Army Corps did not follow proper procedure when it gave Dallas-based Energy Transfer Partners the go-ahead to build the pipeline."

The judge is expected to rule Friday on whether to grant the tribe's request for an injunction.

In the tribe's emergency motion, the Standing Rock Sioux accused the developer, Energy Transfer subsidiary Dakota Access LLC, of razing areas on private land that the tribe's cultural expert recently discovered were significant. The tribe described the events in court documents:

"In the afternoon of Friday, September 2, 2016, the [Standing Rock Sioux Tribe] further submitted recently discovered evidence of an astonishing archaeological find. This find concerned historically, culturally, and religiously important stone features and grave markings to the successors of the Great Sioux Nation, including graves of chiefs, warriors and Bear Medicine healers. These formations and grave sites are adjacent to and in the pipeline's proposed right-of-way approximately 1 to 2 miles away from the Lake Oahe crossing site. Less than 24 hours after SRST's filing, Dakota Access desecrated and destroyed the sites described in SRST's declaration."

The company responded that it "is not destroying and has not destroyed any evidence or important historical sites."

Tribal Chairman Dave Archambault II told Prairie Public Broadcasting that he is disappointed with Tuesday's restraining order "because I know more of our sacred sites are going to be destroyed. ... I'm OK with the fact that we know there's not going to be any construction near the camp on the east side of Highway 1806. I'm not happy with the ruling, however, because there's a lot of land being destroyed."

Tensions over the pipeline have escalated recently. Hundreds of Native Americans from tribes nationwide have camped near the construction site in North Dakota. As we reported, "one demonstration over the weekend turned violent. Some protesters ended up bloodied and the local sheriff said three private security officers had been hurt."

In a video posted to Facebook on Tuesday, Archambault said that "we still have to remain peaceful and respectful. We still have to think about what we're going to leave behind after all of this."

He added: "It's not over. We still have a long ways to go."

In a separate incident, North Dakota authorities have issued arrest warrants against Green Party presidential candidate Jill Stein and vice presidential candidate Ajamu Baraka on charges of criminal trespass and criminal mischief. "Video displays Stein and Baraka spray painting construction equipment on private property," the Morton County Sheriff's Department said in a post on Facebook, adding that the crimes allegedly happened during a protest on Tuesday.

Stein addressed the possibility of charges in a post on Twitter on Tuesday, and then asked, "Will they charge the oil company that razed sacred burial grounds?"

That's what we do at Barnard. Whether we're raising a dam in Alaska, constructing a reservoir in Florida, tunneling under downtown San Francisco, redirecting a river while building a complex hydropower plant in northern Manitoba, or strengthening and improving the integrity of a natural gas pipeline in a Sacramento suburb, our people arrive at our projects with a determination to do the best for their communities and be the best in the industry.

Tutor Perini is a large construction company that has an office in NYC.  I know a friend that is an architect working for them and he has said that it is wonderful working for them.  Tutor Perini is currently working on the Hudson Yards project which is the largest project in NYC ever.  Projects that large really interest me as to how they are even feasible.  I want to be able to join the industry and help manage a multi million dollar project and say that I was a part of it.  Something that will be around for long after I am no longer around.

http://www.eccoiii.com/ECCOIII is a small construction company but it still competes with the big guys.  I worked with ECCOIII along side Skanska a year ago and learned that in construction it doesn't always matter how big you are but how well you perform.  I love working in an industry that takes pride in quality workmanship.

Whiting-Turner is one of the oldest construction companies that I can think of.  They are over 100 years old and one of the leaders in the construction industry.  I had the privilege to be able to intern for them this past summer.  Working on a Hospital job with Whiting-Turner made me realize that no matter the size of the project, as this was a small renovation, they take the project very seriously. I would be very happy to be able to work for Whiting-Turner again in the future.

Eighty four years ago this month, the Holland Tunnel, linking the island of Manhattan to New Jersey under the Hudson River in the USA, opened to traffic. Two 16ft long shields, weighing 400 tons, excavated the twin tubes. On a good day, the shields, with a forward thrust of 6,000 tons, advanced 40ft.
