The phrase “America’s crumbling infrastructure” has been said over and over again the past few years. It’s why we’ve seen such a large uptick in bridge demolitions, a rise in innovative processes to reduce the time it takes to replace bridges, and the reason for President Trump’s emphasis on spending $1 trillion over the next 10 years to fix them.
But where are all the bridges? Thanks to help the National Bridge Inventory, the Washington Post was able to grab data from their latest update and place all of the structurally deficient bridges onto an interactive map. The National Bridge Inventory places poorly performing bridges into 2 categories: functionally obsolete and structurally deficient. Functionally obsolete bridges may or may not be structurally sound, but underperform in other ways, like not having enough lanes or the lack of an emergency shoulder. Structurally deficient bridges are those “that have one or more structural defects that require attention.”
The National Bridge Inventory data states that more than 130,000 bridges are either structurally deficient or functionally obsolete. According to USA Today, 55,710 bridges were considered structurally deficient in 2016, which is actually down slightly as compared to 2015. USA Today reported that the top five states with the most structurally deficient bridges are Iowa (4,968), Pennsylvania (4,506), Oklahoma (3,460), Missouri (3,195), and Nebraska (2,361).
Bridges are graded based upon their overall sufficiency scores, and the Washington Post reported that the bridges with the lowest sufficiency scores will be prioritized for federal financing. Because the bridge data is only current through 2015, there are still a lot of bridges on the list that have already been demolished, like the Washita River Bridge in Oklahoma.

At the end of March 2017, a massive fire underneath Atlanta’s I-85, a major highway that handles around 243,000 vehicles each day, caused a large section to collapse. Since then, it has left traffic in the area in rough shape, and Atlanta is already known for their bad traffic, especially ITP. That’s hip Atlanta terminology that stands for “Inside the Perimeter,” or inside of the 285 outer belt.
Many could argue that peanut butter and jelly or spaghetti and meat balls go together about as well as cursing and construction job site. Sometimes I find myself surprised that there are more curse words written into construction proposals.
Construction industry groups are applauding President Donald Trump’s decision to sign a measure that eliminates a rule that would allow OSHA to issue citations for recordkeeping violations up to 5 years old. The previous statute of limitations was 6 months.
It’s that time again to begin Construction Junkie’s annual search for the best construction podcast! Last year, newcomer to the scene ConTechTrio took home the crown for best podcast and they’re continuing to make waves on the platform, with interviews with heavy hitter guests from the world of construction each episode. 2015’s winner was Cesar Abeid’s Construction Industry Podcast, but unfortunately there have not been any new shows released since August of 2015.

One of the most challenging issues with modular construction, of any kind, is the sheer size and weight of many of the components that need to be transported and lifted in place once onsite. That presents a specifically tough situation for jobsites that are not easy to get to. Arup, a design, engineering, and consulting team in the United Kingdom, has developed and successfully implemented what they say is the “world’s first modular glass-fiber, reinforced polymer bridge.” You may remember Arup from their testing of a “living wall” scaffolding cover that we wrote about last year.
Prior to January 20th, 2017, it was almost a daily occurrence for the Occupational Safety and Health Administration (OSHA) to issue a press release about a large fine they have recently levied against businesses. Since January 20th, news coming directly from OSHA has been extremely sparse. There were some updates, like the delay of their new silica dust exposure rule and information about their “Safe and Sound Campaign,” but nothing about recent fines and citations.
Originally set to be enforced on June 23, 2017, the Occupational Safety and Health Administration new rule regarding silica dust exposure limits has been delayed an additional 90 days, to September 23, 2017. Many construction industry groups were upset by the new rule, as they deemed it “technologically and economically infeasible, but also unnecessary.”
In 2015, Milwaukee released their robust smart tool management platform, ONE-KEY. The smartphone and web application allows users to not only keep data of their tools spread across different users and jobsites, but it also offers tool customization and tool tracking, for tools that are enabled with ONE-KEY. Earlier this year, the platform got a major upgrade with the release of added tool security, which allow users to hide tools, lock the trigger or footpad, or completely render the tool useless remotely if lost or stolen.

The Bosch REAXX Jobsite Table Saw has been on a bit of a roller coaster ride since it was announced in 2015. SawStop, the first company to market with a table saw that detects flesh and stops the blade, filed a lawsuit against Bosch for patent infringement in mid-2015. That lawsuit delayed the release of REAXX to 2016, a year after the company planned to release it. The ruling in that case has put another speed bump in the rollout plans for Bosch.
3D printing has had to overcome plenty of obstacles, including materials, mobility, weather, and height. Slowly, but surely, technology companies are beginning to overcome these challenges. A 400 square foot house was recently printed in concrete on-site, in less than 24 hours and in freezing temperatures. Other companies are working on perfecting 3D printed steel for pedestrian bridges. Height limitations seem to be the hardest problem to solve, however.
