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.

On October 12, tragedy struck at a construction site in New Orleans, when an 18-story under-construction hotel partially collapsed, killing 3. Due to the unstable tower cranes on site, crews have yet to be able to recover 2 of the bodies inside the building.
A couple of years ago, we shared an article about how Los Angeles was painting certain asphalt roads with a light, paint-like material made by CoolSense. Their hope was that it would reduce heat island effect in the warmest part of their city. A recent study has found that the coating may not actually have the effect that the city was hoping for.
Many construction companies require their employees to get either an OSHA 10 or OSHA 30 safety certification, but there are a few different ways to take the courses. Throughout my career, I’ve had safety training in a few different capacity: in-person classroom as part of my construction management degree curriculum, a work organized 10-hour course, and, most recently, an OSHA 30 online course.
For the past 5 years, construction technology company, Procore, has hosted their customers and tech enthusiasts at a multi-day conference called Groundbreak. There’s been significant growth since the events humble beginnings, not only in just attendees, but in the conference’s offerings.
This was my second time attending Groundbreak and, in case you couldn’t make it, here are the highlights of the items you missed:
Tragedy struck in New Orleans over the weekend when an under construction 18-story hotel suddenly collapsed, killing at least 2 with 1 still missing and injuring up to 30 others.
For nearly 3 years, an update to the overtime pay rule was held up in court battles, but we may finally have a resolution. The update sought to increase the minimum salary threshold of workers that are exempt from being paid overtime pay for any overs worked over the traditional 40 hour work week.
If you want your construction company to be best-in-class, you need to be able to objectively measure yourself against them. To help assist with that difficult task, Autodesk has announced the release of a new self-assessment tool to measure where your company stands against your competitors based upon 7 different key performance indicators (KPIs).
In a recent press release, OSHA announced that it has implemented a new OSHA Weighting System (OWS) for their 2020 fiscal year. The change will better help OSHA allocate their resources where needed.
Just days ahead of their annual Groundbreak conference, Procore has announced a new feature upgrade to their platform called Embedded Experience.
Infrastructure projects can require some pretty massive heavy equipment to perform all necessary tasks, so it’s a great opportunity to get some stunning footage of the machines and workers during the process.
