One of the toughest aspects of construction in heavily populated or close-quarters areas is the control of noise and other pollutants. The public’s worries about these items can stall or kill projects before they begin. If and when they project actually begins, complaints can roll into the governing agencies causing project delays and/or fines.
Arup, a design, engineering, and consulting team in the United Kingdom, has been developing a living wall system, which they think can reduce the noise and improve the air quality surrounding ongoing construction projects. Manufactured by the Swedish company, Green Fortune, the living wall is currently being tested on a renovation of the St. Mark’s building in Mayfair, London.
“Living Wall Lite,” as the wall system is being called, is made up of grasses, flowers, and wild strawberries and covers the scaffolding system, which faces the public street. Initial tests of the 861 square foot (80m²) wall have shown that it can reduce noise pollution up to 10 decibels. The test wall in Mayfair has several sensors installed to measure real world impacts of noise reduction, temperature, and air pollution.
“Living Wall Lite has the potential to transform scaffolding and hoardings into much more than just a cover up. By introducing plants and flowers, we can create a more attractive and healthier environment for local residents, businesses and workers on site,” said Alistair Law, Façade Engineer and the Living Wall Lite’s developer, Arup, in a press release.
There’s no doubt that construction can have some pretty substantial impacts on neighboring property values and businesses, so anything that can reduce those impacts will certainly help new construction efforts. What remains to be seen with this wall is two-fold: will this technology actually help with noise and air pollution and will safety agencies approve of its use. The sensors will give Arup all of the data it needs to prove or disprove the concept, but reactions from governing safety agencies remains to be seen.
Over the past 12 months, scaffolding issues were the second most cited OSHA standard, trailing only duty to have fall protection on the list. 3,141 citations were issued, totaling $6,486,743 dollars for failure to comply with OSHA standard 1926.451 General Requirements- Scaffolds. Since the living wall will cover up the vast majority of the exterior side of the scaffolding, it will be much more difficult to assess any issues from that side. You have to wonder how OSHA and the UK’s Health and Safety Executive (HSE) would respond.
No pricing information on the wall has been released yet.
What do you think about this living wall system? Does it have a future on the jobsite?
The Netherlands has a ton of bridges, especially pedestrian and biking bridges, thanks to its abundant system of canals. Perhaps because of that, they have become a leader in 3D printing technology when it comes to bridges.
Concrete is an extremely strong building material, but has a notoriously weak tensile strength. In order to resist tension, bending, and shear forces, steel rebar or other reinforcement materials are added either prior to the placement or into the mix. Even with reinforcement, concrete is still extremely rigid and prone to cracking. In the event of a major earthquake, the uneven and horizontal forces can cause structures to crack and, in the worst case, cause failure.
Concrete can adapt to any shape its formwork calls for while it’s being placed. While it’s POSSIBLE to make intricate designs with the material, it’s not always easy or practical to do so. Researchers from ETH Zurich have designed a new method of forming and placing an ultra-thin, curved concrete roof system that they plan on installing on a construction project next year.
As electric vehicles are becoming more and more popular around the world, researchers are trying to find ways to adapt the technology to heavier duty applications. Due to the large size of projects and amount of money in the industry, the mining industry has seen its fair share of technological advancement. Several manufacturers, like Komatsu, have developed and released driverless dump trucks for mining operations in the past few years. A team of companies in Switzerland is now working on a gigantic battery powered dump truck that will be tested for 10 years.
Rapid growth and the industrialization are the major contributors to China’s noted air quality issues. 4 years ago, the Chinese government issued a “war on pollution” aiming to improve air quality and reduce other environmental hazards, such as land and water contamination. Air quality is at its worst in the winter months across the country, due to households relying more on coal power to heat residents’ homes.
Asphalt is one of the world’s most popular pavement materials. Because of that, researchers and scientists are constantly looking for ways to improve upon it. Additives have been included in some asphalt mixes for years to improve strength, but recently researchers have been getting pretty clever with the types of additives they’re testing.
As great as a product as asphalt is, there’s no doubt that there is room for improvement. Scientists all over the world are trying to solve its most common issues, such as potholes, cracking, ice build-up, and storm water drainage. Los Angeles is now tackling another issue with the material: heat island effect.
In March of this year, Elon Musk announced that Tesla would begin taking orders on their Solar Roof Shingle concept. Tesla Solar Roof is a solar power roof system that eliminates the need for bulky solar panels installed over top of traditional roof materials. Instead, the shingles themselves, which come in a variety of different styles, are the solar panels.
At the company’s second quarter earnings report, Tesla announced that the first solar roof installations have been completed.
Standard vertical elevators have had it too good, for too long. After the first cable dependent elevator was unveiled in 1857, not much has changed in the elevator industry. They’re still using cable systems and still only going up and down. But not anymore. ThyssenKrupp has officially made a multi-directional elevator a reality.
There’s no shortage of company’s trying to improve the world’s roadways. Asphalt and concrete each have their own disadvantages, especially when maintenance environmental factors are taken into consideration. Plastic is a major problem for landfills, as well, as it can take an estimated 500 years to fully decompose. One UK company believes they can solve both maintenance and environmental problems through the use of recycled plastic.
