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.
DB Export, a New Zealand beer company, has built glass beer bottle crushing machines that they hope can help save the world’s sand reserves. The machine has a beer bottle specific shape that they say removes the label and the silica dust, while turning the glass into 200 grams of sand substitute in 5 seconds.
AdWeek reports that DB Export has already reached a deal with New Zealand’s largest producer of bagged concrete, DryMix. That’s a pretty big deal. More than 28 billion glass jars and bottles end up in landfills every year in America, according to Recycle Across America, so not only could this process help our industry, it could also greatly reduce the size of landfills.
DB Export isn’t alone in their quest to recycle bottles to be used in construction, either. An American company, ByFusion, has developed a process to smash plastic bottles into non-structural building blocks that can be used in light duty applications.

A new 21-story apartment building proposed for Milwaukee, Wisconsin as received unanimous approval from the City Plan Commission. If built, the new tower could possibly be North America’s tallest mass timber building.
The USGBC recently released their 2018 ranking of the Top 10 US States for LEED construction, which is sorted by Gross Square Footage per Capita. That ranking system allows them to get a fair comparison of states, despite differences in population and number of buildings.
Tall buildings made with structural timber have been on the rise in Canada and European countries in recent years, but the United States has been slower to adopt the method due to code restrictions. The state of Oregon recently released an addendum to their building code to allow taller mass timber buildings in the state and an upcoming International Code Council (ICC) vote could encourage more states to follow suit.
You may have been sitting in your house or office one day and noticed the distinct sound of a bird hitting the window. It’s pretty common, as it’s estimated that as many as 988 million birds die in the US each year by colliding into glass. The new arena that will house the NBA’s Milwaukee Bucks has incorporated some design elements that will reduce the amount of birds killed by the massive structure, allowing it to be dubbed the “World’s Most Bird Friendly Sports Arena.”
Dubai has been on the bleeding edge of pushing the boundaries of construction for over a decade. The famous Burj Khalifa, the current World’s Tallest Building, but the United Arab Emirates on the map. Since then, the country has poured money and resources into the construction industry and have sets their sights on a new challenge: 3D construction printing.
Across the United States, any mass timber building designed to be taller than six stories high has to receive special approval from the building codes department. After a recent addendum was added to the Oregon’s building code, the state has become the first in the country to allow high rise mass timber buildings without receiving any special considerations.
Last summer, Tesla announced that the first of their solar roof tiles had been installed on test houses. However, as has become customary with many Tesla products, the company is experiencing significant manufacturing delays.
Since the dawn of green buildings, these projects have always been synonymous with LEED certification. The process of obtaining that LEED certification has not always been an easy one for contractors; there is a ton of paperwork and documentation that needs to take place in order to prove all LEED credits have been rightfully earned. A new construction standard, called BREEAM, is hoping to disrupt the United States’ green building certification world with its impending New Construction Standard Release in 2019.
One of the biggest hassles of site work in construction is the hauling away of spoils. It’s costly and time consuming to bring in truck after truck to take unneeded soil off to an unknown dump site. When Elon Musk and his team, The Boring Company, started digging a tunnel for a HyperLoop system in Los Angeles, they knew there had to be a better way to handle to soil than to haul it away.
