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.

One of the best parts (for me, anyway) of large developments that cost hundreds of millions of dollars being built is being able to learn about different construction methods that can reduce costs or deliver the project sooner than traditional methods. The Crown Sydney, a future 890 foot tall tower in Australia, is using a method called “top down construction” to shorten their project schedule and avoid additional hazards on the $740 million project.
If not for having the lowest cost of living in the country, according to the MERIC data, MIssissippi would be in contention for the lowest ranking on our list. However, having a 14.5% lower than the national average boosted the state up 15 spots to #35 after adjustment.
In January of 2018, ten construction workers were killed and another eight were injured when a bridge spanning the Chirajara canyon in Columbia partially collapsed. That collapse has since been blamed on a poor design, reports have stated. Last week, the remaining sections of the bridge were demolished in dramatic fashion.
A 47 year old crane operator is facing charges of driving while intoxicated and leaving the scene of an accident after driving a truck mounted crane into several vehicles on the Long Island Expressway in New York.
OSHA's new crystalline silica dust exposure regulations officially went into effect on September 23, 2017. Over the past 10 months, there has been plenty of confusion about the lung disease causing material. In the first 6 months after the effective date, OSHA's inspectors yielded 116 violations across the country.
Vermont is one of the few states in the Northeast that doesn't have a ridiculously high cost of living, according to MERIC, at only 2.9% higher than the national average. That helped Vermont rank higher than many others in the Northeast in this list, but it's lower than average adjusted hourly rates for the construction industry still kept it on the bottom half of the list overall.
A couple weeks ago, we shared a list of the 100 tallest buildings to ever be demolished. One of the most interesting things that I learned while researching for that article was that although Detroit’s Greater Department Hudson Store was not the tallest building on the list (it was #21), it was the tallest on the list to actually be imploded.
Since the dawn of green buildings, these projects have always been synonymous with LEED certification. The process of obtaining that LEED certification has not always been an easy one for contractors; there is a ton of paperwork and documentation that needs to take place in order to prove all LEED credits have been rightfully earned. A new construction standard, called BREEAM, is hoping to disrupt the United States’ green building certification world with its impending New Construction Standard Release in 2019.
