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.

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.
One of the key components of BIM is the ability to detect clashes, which are design coordination issues that result in the inability to construct a building as drawn. The use of 3-dimensional drawings allows contractors –and software- to detect if key building components are intersecting before it’s about to be installed in the field. Autodesk BIM 360 has recently updated its clash detection abilities within its Model Coordination module more easily and efficiently within its platform.
Hot off of the acquisition of Honest Buildings, a project management software aimed at owners and developers, Procore has announced they have acquired yet another tech company to help bolster their offerings.
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.
For years, Milwaukee has made it very clear that they will continue to keep their M18 platform as their core system. Cordless tool users spend a ton of money into batteries these days, and the company’s goal is to not force them into investing into a new cordless system. That means that Milwaukee has to come up with innovative ways to provide the tools users want while being limited to 18 volts.
The spring of 2019 saw 3 trench collapse deaths in a span of 10 days. One at a home construction site in Colorado, another during a culvert install in Marysville, Ohio, and a third at a residential site in Sugarcreek Township, Ohio. The latter has recently received a hefty fine and penalty from OSHA.
Personal fall protection devices are extremely important to saving lives and preventing injuries due to falls on a jobsite. Half the battle is getting your team to wear harnesses, but when they do, you need to trust that the devices will work when they’re needed. 3M has recently issued an immediate stop use and product recall on two of their fall protection products.
Construction Management software company, Procore, initially launched their annual technology conference, Groundbreak, back in 2015. Originally hosted at their headquarters in California, the event has grown exponentially from that first year and this year may be its biggest yet.
