There’s no better way to make hundreds of thousands of people angry than top shut down a highly traveled road on a work day. Because of that, the pressure is on for many companies to demolish overpasses in less than a day and open the road back up in time for morning traffic.
In June of 2015, the city of Bandford in Ontario, Canada allowed Priestly Demolition roughly 10 hours to completely remove an overpass over the 6 lane highway 400 and then disappear without a trace. To add pressure to the job, the city was also ready to exercise liquidated damages if the crews could not complete in time.
To get the job done, the demolition company used a total of 6 excavators (2 shears and 4 hammers), 3 loaders, and 2 bulldozers. That’s 11 pieces of heavy machinery in a space that could open fit 6 cars, so the process had to be well planned and everyone had to be on the same page to make it work. The timelapse is pretty incredible to watch, so much so it could give the ballet a run for its money. Move over Nutcracker.
On October 12, tragedy struck at a construction site in New Orleans, when an 18-story under-construction hotel partially collapsed, killing 3. Due to the unstable tower cranes on site, crews have yet to be able to recover 2 of the bodies inside the building.
Tragedy struck in New Orleans over the weekend when an under construction 18-story hotel suddenly collapsed, killing at least 2 with 1 still missing and injuring up to 30 others.
Infrastructure projects can require some pretty massive heavy equipment to perform all necessary tasks, so it’s a great opportunity to get some stunning footage of the machines and workers during the process.
Drones are used for a variety of different tasks on construction sites, like for tracking employees, calculating the volume of on-site stockpiles, or even performing OSHA inspections, but I’ve never actually seen any tools attached to them before. Well, engineers recently strapped a nail gun to one to see if it could potentially perform roof shingle installation.
The most popular method of demolition these days is by implosion, but not always welcome in certain areas or situations. The use of explosives can greatly damage neighboring buildings and spread hazardous materials over a large radius, which is why a cooling tower at the Mülheim-Kärlich power plant in Germany had to be slowly dismantled from the top.
After causing devastation in the Bahamas, Hurricane Dorian worked its way up the U.S. East Coast last week and eventually made its way up to Nova Scotia, Canada as a Category 2 storm. The storm left more than 369,000 without power in the Canadian Region, according to CBC, but also caused a tower crane to buckle and collapse in the city of Halifax.
While placing concrete on the 7th floor of a new hotel in Houston, TX, 16 construction workers were suddenly sent falling to the 6th floor below, sending 9 of them to the hospital, according to local news reports.
As a storm blew through the Dallas, Texas area on Sunday afternoon, a tower crane standing near an occupied apartment building collapsed causing at least one fatality and 6 injuries.
