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.

Caterpillar is not resting on what made it successful in the past anymore and probably for good reason. The equipment manufacturing giant recently bought Yard Club, a heavy construction equipment sharing company, looking to take advantage of the recently popularized sharing economy. Earlier this month, Caterpillar invested $2 million in Fastbrick Robotics, an Australian robotic technology company.
Augmented and Virtual Reality has always been designated for large headsets. Even with recent developments in the construction industry, like Microsoft Hololens and the DAQRI Smart Helmet, if you want to experience AR, you have to get used to wearing something you’re not used to around a job site. As cool as both of those technologies are, it seems that the ole trusty smartphones and tablets have been overlooked. A Danish BIM company has developed a smartphone and tablet application that leaves the headsets behind.
Just last November, a massive Five-Alarm fire rocked a multi-story residential building that was almost 80% complete at the time, completely destroying the project. This month, yet another multi-story residential tower that was almost complete caught fire, making it the 5th in 5 year to suffer the same fate. At least 3 of the previous 3 fires have been ruled as arson but, up to this point, no arrests for any of the previous arsons have been made.
Buildings are demolished all the time in order to make way for new construction. The buildings that are demolished have usually lived out their useful life and are no longer functional. Recently a demolition video resurfaced, which shows a 27 story building in China being imploded. The strange thing is that, since it was finished in 1999, the building had never even been used.
In January of 2017, OSHA released a final rule which greatly reduced the allowable exposure to beryllium, a mineral that can cause deadly lung disease. While not as commonly encountered in the construction industry as other substances that cause terrible lung diseases, like crystalline silica and asbestos, beryllium is linked to a disease called chronic beryllium disease, which kills around 100 people each year. It’s commonly found in coal slag, which is used for sandblasting. According to the New York Times, OSHA estimates that 11,500 construction workers would be affected by OSHA’s reduced exposure limit.
There are a lot of people that would be pretty unhappy with whoever tears down a 98 foot tall, 105 year old tree to make room for a building expansion. In order for most projects to work financially, however, many trees are uprooted and replaced with smaller trees. That’s not what happened with what is believed to be the state of Idaho’s largest sequoia tree, however.
Many contractors and repair technicians live out of their truck and Milwaukee Tool knows this. That’s why they’ve just released an M12 and M18 battery charger that plugs into the c12V DC outlet in your truck or van! As added security, the charger will automatically shut down if it senses that your vehicle’s battery is getting too low. Smart and ultra-convenient.
We know a lot of you out there could use this charger, so we teamed up with Milwaukee to give YOU the chance to WIN one! There are 4 ways to enter below!
As recently highlighted by several multi-story building fires, contractors should always be prepared in the event a fire starts on a job site. There have been dozens multi-story building fires in the past few years and many were started when the building was topped out. In most cases, the project was completely destroyed, leaving developers and owners to deal with years of delays from insurance claims. A massive five-alarm fire at an Oakland construction site is one of the more recent examples.
It’s pretty amazing all of the things that smartphones can do right now. While some wish phones would go back to “just making dang blasted phone calls, like the good ole days,” it’s clear that phone’s will always be more than that moving forward. Through apps and other attachments, phones can now turn into a thermal imagine camera, an x-ray vision scanner to see what’s behind walls, a laser measure, and now an augmented reality tape measure.
In a year that OSHA can’t seem to enforce any new rules, it appears to have found a way to remove a rule from its books. As announced last week, OSHA has removed monorail hoists from Subpart CC – Cranes and Derricks in Construction. Employers are still required to follow other OSHA regulations regarding the hoists, but this rule should help clear up some inconsistencies.
