3.1 miles of bridge does not equal 3.1 miles of on grade highway. In fact, it’s not even close. In order to build the new New York Bridge, which is replacing the existing Tappan Zee bridge that crosses the Hudson River, 14 miles of main span cables, 50 miles of foundation pilings, 300 thousand cubic yards of concrete, and 220 million pounds of steel are needed to complete the structure. Oh, it’s also going to take another 2 years to build, on top of the 3 they’ve already been working on it.
The existing Tappan Zee Bridge was built in 1955 and handles around 138,000 vehicles per day. After realizing that, it’s even more amazing that no cars were hit when a crane, which was working on the new bridge adjacent to the existing, collapsed onto the existing bridge back in July. Without the added danger of nearby construction, the Tappan Zee was already a hazard by itself. According to the New NY Bridge’s website, that stretch of road was the scene of an average of twice as many accidents as the rest of the NY Thruway system, which is a collection of highways. It has narrow lanes and no emergency shoulders, which can be a recipe for disaster.
The new bridge will contain 8 wider lanes for safer and quicker traffic, not including the emergency lanes, and has also been designed to handle a future commuter rail. Pedestrians and bicyclists will also have their own lane to cross the river safely. In total, the bridge will cost almost $4 billion dollars (3.98 to be exact) and will finish sometime in 2018. We’re sure the NY drivers can’t wait until it’s complete.
Many companies were involved in the design and construction of this bridge, which together are known as the Tappan Zee Constructors, LLC. Companies in the group include Flour, American Bridge, Granite, Taylor Bros, HDR, Buckland & Taylor, URS, and GZA.

Bluebeam Revu is a very popular PDF markup and collaboration tool for the construction industry. Each year, the technology company updates its flagship program to adapt to how their customers currently use the program and makes changes to increase their productivity. Bluebeam recently announced the launch of Revu 2018 and we have a breakdown of all of the changes.
Overall, Oregon was in the middle of the pack with regards to hourly wage for the 25 construction professions analyzed, with an average ranking of 18. However, the Northwest state has the 3rd highest cost of living, according to MERIC, as it costs 31% more to live there versus the average state.
The construction industry has never been one to freely share information without charging a fee. That’s changed slightly recently, with some major players willing to provide useful tools and information to help us become better. For instance, we recently shared that Procore has released hundreds of free continuing education courses on their education platform. Another useful site we’ve found recently has shared dozens of toolbox talks to help your team on the jobsite learn about safety.
[guest post] The reality is that construction workers, who already face hundreds of hazards just by working in the industry, are also often at risk for becoming injured or ill due to contact with wildlife.
Back in 2015, engineers at MX3D made a huge announcement: they were going to 3D print a steel pedestrian bridge on-site. That plan has been altered slightly in the nearly 3 years since the announcement, but the group recently completed printing the full span of the bridge.
Maryland is ranked 7th in highest cost of living wages according to MERIC, which dropped their overall hourly wage ranking from around 20th to the 48th ranked state.
Demolitions by implosion seems like the easiest way to knock down a structure, but there is so much preparation that goes into it that even the slightest mistake can have a huge impact. When smokestacks are demolished correctly, it can be a thing of beauty, like when these two silos in Scotland hit each other midair or when this asbestos filled stack was precisely demolished to fall into a pool of water. Things didn’t go so smoothly for demolition crews in Denmark last week, however.
It should be obvious that formal safety training is extremely important to running a successful safety program on any construction site. The most common route for construction employers to train their staff is through OSHA 10 and OSHA 30 courses, but, in the past, it was pretty confusing to determine who was actually authorized to teach the courses and where to find them.
[guest post] Spring is here and before we know it, summer will follow. In both seasons, weather conditions can present dangers to construction workers. Without education and preparation, workers may find that they are seriously ill or injured during work.
