In 1984, Ronald Reagan was president, the Detroit Tigers won the World Series, The Los Angeles Raiders won the Super Bowl, and Beverly Hills Cop was the biggest box office hit. Needless to say, a lot has changed since 1984, especially how many of our cities look. Google has recently released timelapse videos of 193 major cities across the world to show how much they have changed in the past 32 years.
Sometimes it’s hard to gauge the degree in which things change unless you can see it in context, that’s what’s so great about these videos. You might remember specific things about the city you’re from, but it’s hard to visualize all of those from ground level. All of the videos below have been shared on Youtube by the Google Earth team, but these are only a small portion of all the videos available. We chose the cities below, as they’re relevant to the construction industry and most have seen impressive growth over the past three decades. If you’re interested in viewing more, there are some other interesting videos of glaciers, rain forests, and bodies of water which can tell an interesting story. You can view the entire playlist by clicking here.
If you want even more interactivity, the Google Earth Engine website allows you to zoom and pan across the entire globe to get the exact view you want. I made the custom video below of several different areas of Dubai using the Timelapse Tour Editor:
Dubai has seen incredible growth over the past 32 years and obviously has an impressive collection of enormous towers, including the Burj Khalifa. I find the amount of man-made islands that the country has created particularly interesting.
Las Vegas, Nevada

Mistakes during demolitions happen. Sometimes contractors knock down the wrong buildings, other times the explosives used don’t knock the building over, and other demolitions are carried out with a complete lack of regard for human life. As fun as they are to perform and watch, they’re inherently dangerous and there should be a plan in place in case things go wrong.
Construction sites can often be some pretty spooky places, especially when unexpected items and creatures, like human remains, are found on the property. They can also be the site of some heavy superstition, like at several projects in Iceland that were believed to be delayed by hidden elves. But, according to one contractor, there’s something especially spooky about the childhood home of serial killer Ted Bundy.
Cranes collapse for a variety of different reasons. Some are overloaded, some catch on fire, and others succumb to high wind loads. Regardless of the reason, a falling crane can cause tons of damage and have the potential to kill on-site workers and pedestrians walking near the job site.
A recent crawler crane collapse in Northern Italy could have been much worse as the crane, carrying a large section of viaduct, crashed to the ground.
On January 1, 2017, OSHA officially put into effect a revision to workplace injury and illness reporting that requires certain employers to submit recorded information of these instances electronically. Companies were to submit all of this information from the previous year (2016) by July 1, 2017, but now that due date is in jeopardy.
There’s no shortage of company’s trying to improve the world’s roadways. Asphalt and concrete each have their own disadvantages, especially when maintenance environmental factors are taken into consideration. Plastic is a major problem for landfills, as well, as it can take an estimated 500 years to fully decompose. One UK company believes they can solve both maintenance and environmental problems through the use of recycled plastic.
According to the US Department of Labor (US DOL), the construction industry has the highest rate of current drug users (15.6%) as compared to any other industry in the United States. As the city of New York grapples with trying to reduce their alarming rate of injuries and fatalities on construction sites, the New York chapter of the Associated Builders and Contractors (ABC) has proposed that lawmakers add mandatory drug and alcohol testing for construction workers to the law books, according to the New York Daily News.
Feeling the pressure of 9 straight quarters with a decline in total revenue, Caterpillar has acquired the equipment sharing startup, Yard Club, to get help dig themselves out of the dirt. Their most recent quarter was the company’s first positive revenue quarter since November of 2012.
I’m a firm believer that before robots start taking over construction jobs, we’ll first be working with robotics to make workers more efficient and our job sites more functional. Instead of using 3D printing robots to build an entire project, why not use them first to create intricate details and bring character back to buildings? Instead of pushing human labor out of the way, why not use robotics to enhance the abilities of our workers, to improve their health and productivity? With rise in development commercial exoskeletons, workers will soon be able to harness additional strength by just slipping on a suit.
Traffic in Atlanta sucks, there’s really no other way to say it. So imagine the tough position commuters and city officials were put in when a bridge of a major highway on the north side of the city caught fire on March 20, 2017 and was damaged beyond repair. 243,000 motorists were forced to find alternate routes to work for the estimated 3 months that it was going to take to rebuild it. Now, imagine how thrilled they were when the highway opened back up one month ahead of schedule.
Last year, Tesla announced a new disruptive product to the market in the form of solar roof shingles. Unlike traditional solar roof panels, these shingles mimic the look of traditional terra cotta, clay, and slate tiles, creating a more aesthetically pleasing look. This week, the company began taking pre-orders for the roof shingles and also released a cost calculator.
