The original Port Mann Bridge stood tall in British Columbia for nearly 50 years before officials decided to replace it with a wider bridge of the same name. Built in 1964, was four lanes wide and, at the time it was built was the most expensive stretch of road in Canada. The new bridge it was replaced by spans 10 lanes wide and held the title of the widest bridge in the world until the new San Francisco-Oakland Bay Bridge was completed in 2013.
Demolition of the old bridge began in 2012 when the new bridge officially opened and just finished up in October of 2015. The bridge is located in an extremely busy area with railroad tracks nearby, so several different methods of demolition had to be used. The timelapse below shows 3 years’ worth of worth condensed down to a little more than 30 seconds. I’m sure it didn’t feel anywhere near that short for the crews on site every day. There’s also a bonus video below that that shows on of the 230 foot (70m) long girders being imploded in a blaze of glory.
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.
