It’s hard to believe that it has been 17 years since the terrorist attacks on the World Trade Center in New York City. I came to the realization this week that many of the men and women that are about to enter the workforce will never have a true understanding about how the country felt that day and how it responded. New York is still responding to this day and, even though the skyline will never quite be the same, there are new buildings in their place paying tribute to those who lost their lives that day.Read more
Standing 821 feet (250m) in the New York City skyline, the new 57-story residential tower, called 56 Leonard Street, has opened its doors to residents. The 145 condos that inhabit the high rise range in size from 1,418 square feet to 6,400 square feet and in price from $3.5 million to $50 million. Amazingly, even with those staggering prices, the developer told the New York Times that 92% of the units had sold in 2013, even though the tower officially opened last year.Read more
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.Read more
Atlanta, GA has been busy recently updated their major sports facilities. The new Atlanta Falcon’s new $1.4 Billion football stadium just recently celebrated a milestone as contractors installed the final roof beam. That stadium is scheduled to open before the start of the 2017 NFL season. Before that, however, the Atlanta Braves’ new baseball stadium will officially open in time to kick off the MLB season, which starts on April 2nd.Read more
The NFL is a cash cow and nothing makes that more evident than the soaring costs to build the newest NFL stadiums. The past four stadiums to open were the Minnesota Vikings’ US Bank Stadium (watch timelapse here), the San Francisco 49ers’ Levi’s Stadium, the New York Jets/Giants’ MetLife Stadium, and the Dallas Cowboys’ AT&T Stadium. All four surpassed $1 Billion in construction cost. The first stadium to open after the Millennium was the Cincinnati Bengals’ Paul Brown Stadium, which only cost a miniscule (relatively) $455 million ($626 million in 2016 dollars) to build. The oldest stadium still in use by any NFL team is the Oakland Raiders’ Coliseum, which was completed in 1966 and cost $25.5 million ($186 million in 2016 dollars). That stadium also spent $200 million ($302 million in 2016 dollars) in renovations in 1995 and 1996. As you can see, dollars spent on NFL stadiums have increased significantly in the past few decades and there’s no end in sight.Read more
Not all demolition videos can be implosions and that’s OK, because each type of demolition is its own art form. Sometimes contractors are bound by the constraints of the job, especially when located in an area with a large concentration of pedestrians and other public areas. That was the case for the construction site of the future One Vanderbilt Tower in New York City, which just completed the demolition of five different buildings covering an entire city block.Read more
Yesterday marked the 15 Anniversary of the terrorist attacks on New York's World Trade Centers on September 11, 2001. The attacks left a noticeable hole in the New York skyline for several years after the Twin Towers collapsed, but that hole has since been filled with a new and symbolic tower, the One World Trade Center.Read more
Nobody likes traffic, especially when lane closures and construction are involved. Construction zones are prone to increased accidents, which also put construction workers in extreme danger. The best way to reduce traffic, accidents, and worker injuries is to reduce the on-site schedule, but how do you go about doing that?
The Connecticut Department of Transportation (CDOT) needed to overhaul its highly trafficked Route 8 in Bridgeport, CT which included several bridges. The bridges, which were built in the 1970s, handled over 88,000 vehicles per day and had degraded to a point that the CDOT determined the bridges had reached the end of their useful life. The original estimated schedule for the bridge overhaul was 2 years, which officials determined would be way too long to displace that amount of traffic, so they looked for alternative methods. In the end, the CDOT opted for a Design-Build concept with Manafort Brothers, Inc. and Parsons Brinkerhoff which would ultimately reduce the total on-site work schedule to two 14-periods over the summer of 2016.
The $35 million project not only used Design-Build to shorten the schedule, but also employed the Accelerated Bridge Construction (ABC) technique. To further reduce the schedule, the ABC method utilized Prefabricated Bridge Units (PBUs), which were large sections of the bridge that were fabricated off site. Once substantial completion of the PBUs was reached, the on-sire work began. Each 14 day period wound up closing one direction at a time, which shifted traffic to the opposite side. The new bridges are close to being complete now, with a finish date set for September 2016 and the DOT is hoping that maintenance of the new bridge will be significantly reduced compared to the old bridge. According to the website set up for the Route 8 construction, the bridge design incorporated “modern weathering steel beams that require no paint or maintenance over their anticipated 75 year lifespan.”
While it’s not quite as fast as this this multi-lane overpass that was removed and replaced in 43 hours in China or this 230 foot long tunnel installed under a highway in the Netherlands in just 3 days, it’s definitely a step in the right direction for improving contractor efficiency and public safety.
You can watch a timelapse video of the demolition of the old bridges and the construction of the new, uploaded to Youtube by CME Associates, below:
Why do the athletes get to have all of the fun during the Olympics? We construction workers deserve a little bit of the action, too! In order for American swimmers to be chosen to represent Team USA in the Olympics, they must first qualify at the U.S. Olympic Team Trials, which were held in Omaha, Nebraska this year.Read more
