Holding the distinction of having the world’s tallest building is a coveted milestone for designers, builders, and countries alike, but no one has been able to top the 2,722 foot tall Burj Khalifa yet, since it opened in early 2010. The 2nd tallest tower in the world, the Shanghai Tower, opened 5 years later and stands 2,073 feet tall. Just recently, two more gigantic buildings opened their doors, taking over the 4th and 5th spots on the list for tallest in the world, pushing America’s One World Trade Center into 6th place.
The first to open was the 1,965 foot tall (599m) Ping An Finance Center in Shenzhen China. Designed by supertall building experts Kohn Pederson Fox, the building features 100 floors of office space, as well as a central atrium with retail and restaurants.
Although the Ping An did not break the record for being the world’s tallest, it still holds the record for largest stainless steel facade. Over 1,700 tons of 316L stainless steel was used for the exterior, which Building Design + Construction explained was due to its corrosion resistance against harsh coastal atmosphere of Shenzhen.
Shortly after the Ping An opened up, the Lotte World Tower in Seoul, South Korea officially became the new 5th tallest tower in the world. At 1,819 feet tall, it trails the Ping An by just a little over 100 feet and was also designed by Kohn Pederson Fox.
Like the Ping An, the Lotte also holds a few records of its own, including having the world’s highest glass-bottomed observation deck, the world’s highest swimming pool, and the world’s fastest elevator, according to Building Design + Construction. The observation deck is located on the 118th floor, which 1,640 feet in the air. The swimming pool is stationed way up on the 85th floor and the elevator can take passengers to the top of the building from the ground floor in around 60 seconds.
Back in September, OSHA issued a Notice of Proposed Rulemaking that would extend the deadline for crane operator certification requirements. Although OSHA 1926.1427 has required crane operators to receive certain certifications to be able to operate the machines since 2010, actual enforcement of that rule has been delayed several times.
Drywall, gypsum, sheet rock, wall board, or whatever you call it, has to be installed by someone, so who better than a drywall installer? Some drywallers install the board and also tape and mud the joints, but others only hang the board.
When sanding, drywallers are exposed to a lot of dust, including silica in some cases, which they need to be protected from. The Center for Disease Control suggests using a vaccuum sander or pole sanding to reduce worker's exposure to harmful dust particles
Roofers have one of the most uncomfortable jobs on any construction site, especially when installing a dark roofing material. A traditional black roof, either asphalt shingles or EPDM, can be up to 50 degrees warmer than the surrounding temperatures.
Having said that, let's take a look at how they're paid in each state...
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.
Painters are typically one of the last subcontractors on any construction site, who do their best to beautify the drywall with the colors of the architect's or interior designer's choosing. Some painters are also responsible for mudding drywall, patching holes, sanding, and caulking.
Let's take a look at how an average painter's hourly wage compares in each state...
Just one day after Mayor Bill de Blasio signed a new law requiring at least 40 hours of safety training for all 185,000 of the city’s construction workers, a partial roof collapse at a Brooklyn construction site left 6 workers injured, 2 of them serious.
Project managers and supervisors are responsible for keeping their employees safe and the court system has recently shown that they take that responsibility very seriously. When supervisors act in a negligent manner and people get hurt or killed, they should be held liable.
In doing the research for this analysis, I learned something interesting about the plumbing profession. The term "plumber" comes from the Latin word "plumbum," which means lead. Seems fitting in a profession, fairly or unfairly, stereotyped for exposed butt cracks.
In Roman times, plumbers often worked with lead for conduits, drain pipes, and making baths. Plumbers now work with a variety of different materials, including copper, PVC, ductile iron, among others.
It seems like every month there’s a new robot being debuted for the construction industry, with the promise of reducing costs and improving productivity and safety. There are robots for laying brick and block, placing concrete, and even self-driving mining trucks. The most recent robot to hit the job site is Built Robotics’ Autonomous Track Loader (ATL).
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.
