Football season is fast approaching and every city throughout America is preparing to cheer on their team. There probably isn’t a team more excited to start their year than the Minnesota Vikings this year, as they finally get to plan in their brand new stadium, the US Bank Stadium.
In January of 2014, demolition officially began on the Metrodome, the Vikings previous stadium. The Metrodome, built by Barton-Malow, was home to the Vikings since 1982 and cost around $55 million ($179 million in 2016 dollars). It was also the home stadium for the Minnesota Twins from 1982 to 2009. For football, the old Metrodome held a maximum capacity of 64,121 people.
For the past 2 and a half years, the brand new US Bank Stadium has been under construction, so the Vikings have had to make a temporary home at the University of Minnesota campus, which opened in 2009 and holds a capacity of 52,525. The US Bank Stadium, which is being carried out by Mortenson Construction, officially opened its doors on Saturday, July 23 to allow fans to get their first look of all the hard work that occurred the past two seasons. In total, the new stadium will hold 66,200 people and cost over $1 billion, almost 20 times what the Metrodome cost to build. By comparison, the outlandish AT&T stadium, home of the Dallas Cowboys, cost $1.3 billion and holds a capacity of 80,000 people. Though the new stadium will only hold a couple thousand more attendees, it’s actually almost 2 times larger than the old stadium (1,750,000 vs 900,000 square feet), has over twice the amount of restrooms, over a 100 more concession stands, and a video board 13 times larger than the old.
Below you can watch a combined timelapse video of the demolition of the Metrodome and the construction of US Bank Standium. Below that, you can take a tour of the inside of the new stadium alongside of some of the Vikings players.

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.
Late last year, crane manufacturer, Sarens, announced that their brand new – and enormous – crane, was ready to be sent off to it’s first job. After several months of prep, the Sarens SGC-250 has finally made it onto its intended jobsite and is ready to lift.
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.
Unless you work on infrastructure and some other specialty structures, you’ve probably always wondered how underwater structures are built. It’s always admittedly been a bit of a mystery to me, as I only encounter relatively small amounts of water on my retail construction sites. Some dewatering here and there or a small creek relocation can add some difficulty to a project, but they’re manageable.
As large of an industry as the construction industry is and with the amount of characters that I’ve met in my career, I’ve always been surprised at the lack of television programming covering large building projects. The Construction Channel, an online new media company, is taking matters into their own hands and has recently released episodes of a documentary series called “Six Figures, No Suits” (SFNS)
We have featured Priestly Demolition Inc. (PDI) on Construction Junkie many times, because of one simple fact: they produce high quality and informative videos about their craft. That’s not something many other companies in the construction industry can say – and now it’s paid off for them in the form of a television show.
When you need to demolish a building in a tight downtown setting, you make sure to hire people who have the right experience to do the job. Controlled Demolition, Inc (CDI), was at it again recently, when they shared a video of a recent building implosion in Dallas, TX.
Falls on the jobsite is the leading cause of injuries and fatalities in construction. Keeping up with housekeeping on your site is a great way to reduce risks of falls, but other protections, like rebar caps should be installed when rebar is exposed. A young construction worker recently found out the hard way what happens when rebar is left exposed.
Completed in 1976, the CN Tower in Toronto, Canada held the record for the tallest freestanding structure in the world from 1975-2007, until it was supplanted by Dubai’s Burj Khalifa. At its highest point, the CN Tower, which is mainly used as a communications and observation tower, reaches 1,815.4 feet (533.33m). Last year, the tower underwent a $16 million renovation and Priestly Demolition shared a fascinating, in-depth video for how they took care of the demolition of the interior space and walls.
