On March 15, 2018, a devastating pedestrian bridge that was under construction collapsed onto an open roadway below, killing 1 bridge worker and five motorists, as well as injuring 8 others. As was expected, investigations have been underway since the accident, which are expected to take at least several more months to complete
The National Transportation Safety Board (NTSB) has released preliminary report after the accident and is focused on cracks that formed about 3 weeks prior to the collapse. The group is also evaluating the bridge design, construction materials, and the construction process.
After the collapse happened, it was hard to keep track of what the facts of the incident were and the preliminary report helps to clear up some of the confusion. On the day of the collapse, crews were working on re-tensioning a diagonal member of the bridge after de-tensioning the bridge 5 days prior. A crane was being used to complete the work, so crews shut down 2 of the 3 westbound lanes, but did not close the 5 eastbound lanes.
In the next month, the NTSB stated that they will be conducting some additional forensic examinations of structural components and will also perform destructive testing of core and steel samples.
Once the probable cause of the incident is determined, the NTSB will issue safety recommendations to hopefully prevent something like this from occurring again.
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.
Construction employers are legally responsible for following and enforcing safety regulations on their jobsites. If caught not abiding by these rules and failing to keep workers safe, an OSHA violation and fine can follow. Recently, however, several contractors are also facing criminal charges following employee deaths on their jobsites.
A little over 3 years ago, reports surfaced that San Francisco’s luxury high rise, the Millennium Tower, has been consistently sinking and tilting since it was completed in 2009. Lawsuits have been underway for years involving dozens of lawyers from many different parties, but an expert panel has just approved a $100 million plan to keep the building from sinking and tilting any further.
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)
A 2018 trench collapse in Colorado lead to the death of a construction worker named Rosario “Chayo” Martinez-Lopez. Now, his employer faces manslaughter charges for his death.
It’s not often that contractors completely invent a new method of building high rises. We’ve certainly seen some very interesting methods in recent projects, such as the “top-down” method that allows the sub and super-structure to be built at the same time, but a contractor in London has a new way to shave time off of the construction schedule of a high rise building.
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.
Almost 18 months ago, an under construction pedestrian bridge on Florida International University’s (FIU) campus collapsed, killing 6 people and injuring another 8. While many investigations have closed, including OSHA’s scathing report, families of victims and survivors have been awaiting the results of civil lawsuits filed against the companies in charge of the projects.
There’s no doubt that building rectangles in construction is much easier than making round objects, which is why building a 366 foot tall sphere in the middle of Las Vegas really caught our eye.
According to the most recent data from the Bureau of Labor Statistics, women only account for 9.9% of the workforce in the United States construction industry. To help drive gender diversity in construction and empower women, a new conference will be making its US debut in September, called Women in Construction USA 2019.
