Astronomy and the planets and solar systems within it, are a source of wonderment and awe for many people. Planetariums, which are educational facilities for the hands-on and interactive learning about astronomy, can be found across the world. China is currently building a pretty spectacular planetarium in Shanghai, the country’s biggest city.
When completed in 2020, the Shanghai Planetarium will cover 420,000 gross square feet and will feature a 68 foot diameter digital sky theater, a 60 foot diameter optical planetarium, an IMAX theater, and more. According to Shanghai Daily, the impressive looking structure will cost around $81 million.
Almost every planetarium in the world incorporates a large sphere into the design and construction, and this one is no different, although it does also feature an inverted dome, as well. The design elements were inspired by “astronomical principles” and “invokes the experience of orbital motion” according to the website of the designer, Ennead.
The drone footage below gives a glimpse into the construction process of the planetarium. There is a steel ring truss that supports the 115 foot cantilever and steel sphere where the planetarium theater will be, according to Designboom. I have to admit, it’s always a bit jarring to me to still see bamboo scaffolding.
Check out the video below of the planetarium’s construction progress so far:
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.
Cranes collapsing on-site are serious business, especially since many of them resulted in the loss of life. A recent crane collapse on a construction site in Alpharetta, GA was caught on camera after it caught fire, but luckily no one was injured.
There are a lot of different specialty construction contracting sectors within the industry and cruise ships are definitely one of them. There are plenty of unique challenges when dealing with a moving ship versus a static building. A recent accident highlighted the challenges when a crane collapsed on a cruise ship under renovations, injuring 8 people.
