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?
One of the most challenging issues with modular construction, of any kind, is the sheer size and weight of many of the components that need to be transported and lifted in place once onsite. That presents a specifically tough situation for jobsites that are not easy to get to. Arup, a design, engineering, and consulting team in the United Kingdom, has developed and successfully implemented what they say is the “world’s first modular glass-fiber, reinforced polymer bridge.” You may remember Arup from their testing of a “living wall” scaffolding cover that we wrote about last year.
Snow causes all kinds of travel nightmares and not just on the roads. Snow and ice can cause major airline delays and flight cancellations. Because of these issues (and the large amounts of money to be gained by solving them) several different groups of researchers have been hard at work figuring out ways to reduce and remove snow and ice from pavement without the need for chemicals and snow plows. The first technology to get a full scale test slab installed at an American airport, however, came from Iowa State University professor Halil Ceylan.
Maybe I’ve had my head in the sand for a while (forgive the pun right out of the gate), but I've recently found out that the world is suffering from a shortage of sand. The New York Times reports that the increasing demand of sand from manufacturing and construction in combination with rising sea levels and human development of shores is reaching crisis levels. Sand is used in plenty of construction activities, from mortar to concrete to brick and asphalt. We use a LOT of it. In fact, concrete production takes a whopping 80 percent of all the sand that is mined. So what can we do? One company says the answer is to drink more beer.
Solar roofs are an obviously popular choice for those interested in conserving energy, but traditional panels are extremely clunky and expensive. Tesla and CEO Elon Musk announced last year that they have solved that issue, which the impending release of Tesla Solar Roof, which look like a traditional roof shingle.
3D printing technology faces major issues when it is required to leave the shelter of a warehouse and step foot on a construction job site. 3D printers are extremely large, heavy, and rely on precise calibration for accuracy. Even the first 3D printed office building in Dubai, which was completed last year, had to actually have its components printed off site and assembled on site. But, Apis Cor, a 3D printing company, believes it has created the technology to print a full structure completely on site.
The concept of solar roadways has been in the news a lot recently. Using the millions of miles of roadways throughout the world to also create power seems like a no brainer, the asphalt and concrete we’re using now aren’t really accomplishing anything more than handling the traffic on the road. But, there’s also a very strong reason why those products are used: they’re strong, reliable, and relatively durable. Still, many researchers believe there is a lot of unharnessed potential for roads and the world now has a very strong test subject for the future of solar roadways in Tourouvre-au-Perche, France.
3D printed construction has been on top of the news the past few years, but we have yet to truly see many real world applications of the process. Last year, Dubai unveiled a completed 3D printed office building, which they say was built in only 19 days, but news has been pretty slow until the world’s first 3D printed bridge was completed recently.
It’s no secret that the United States dominates when it comes to LEED certified construction projects. The US actually has more total gross square meters and number of LEED projects than the the other top 10 countries combined, by almost 3 times, totaling 336.84 million gross square meters over 27,699 LEED projects! China, Canada, and India are ranked number 2, 3, and 4, respectively.
The US Green Building Council recently released their annual top 10 list of states for LEED construction in 2016.
Green building is no longer something that can be ignored. According to the USGBC, green building will account for ⅓ of all construction projects by the year 2018, which is now only 1 short year away. Construction is one of the leading industries in regards to the production of greenhouse gases, most notably due to the production of cement, which produces an estimated 5% of all carbon dioxide emissions alone. There are many companies throughout developing new techniques and building products to help reduce the industry’s impact, so here’s a list of 6 products that caught our eye in 2016.
Green building is big business these days and it’s expected to account for 1/3 of all construction projects in the United States by the year 2018. LEED, being the poster child for green construction and the world’s most widely used green building rating system, is expected to directly contribute to 386,000 jobs by 2018, as well. Though green building is a concept used significantly throughout the world, as seen in projects like the world’s first zero energy hotel, the United States absolutely dominates the industry with respect to LEED.
