The 150 year old US Capitol building is currently undergoing its first restoration since 1960. The famous domed building is packed with rusted ornamental cast iron elements and a host of hazardous materials. The Architect of the Capitol has posted periodic updates of its progress throughout the project and the latest is a pretty cool timeline of the scaffold installation on the interior side of the Capitol Rotunda. You can find out more about the $100 restoration project in our previous post about it by clicking here.
As you’ll see in the video, the crews have begun hanging white drapery on the scaffold as the crews begin to remove hazardous lead paint, restore the iron work, install new lighting, and upgrade the HVAC system and electrical. After the video, we’ve shared a few of the amazing up close pictures of the Rotunda restoration, as well as an inside look into how the replacement windows were made in roughly the same manner as they were in 1860.
Many of the historical cupola windows have been badly damaged over the course of the last few decades and needed to be replaced. Obviously, there aren’t going to be many 1860 style windows on the market, so they had to go with the next best thing: re-creation. The original windows had a wavy surface texture which were added to the hot material as it was being rolled out. Both the original and new windows are made of glass, but the new replacement windows have been coated in a polyurethane resin which improves the durability of the glass. Enjoy the video below.
Remote sites have extreme challenges, like finding enough staff to work the jobs and being able to get materials to the site. Large mining operations have turned to self-driving dump trucks, like this 320 Ton mega machine, for a few years now. But, Lockheed Martin, a giant in the world of global security and aerospace, has a different solution for remote sites.
As of early March, there were nearly 200 construction companies that marked themselves as “interested” in constructing the US/Mexico border wall. The Daily Mail now reports that over 600 have expressed interest in the design and construction of the wall. The Request for Proposal (RFP) package for the conceptual design of the wall was released on March 17th and the responses are due no later than March 29th.
The Consumer Product Safety Commission has announced a recall of a Craftsman portable table saw, sold exclusively by Sears Holdings from April 2014 to October 2016 for around $200. The specific saw was manufactured in China by Rexon Industrial Corp, Ltd. of Taiwan.
Early this year, a landslide caused catastrophic failure to the Pfeiffer Canyon Bridge along California’s famous Highway 1. California Transit officials closed the bridge on February 21st and announced it would be demolished and replaced. Time is of the essence as US News reports that over 400 residents are stranded on one side of the bridge and helicopters have had to bring in food for them. The residents are still able to use the footpaths in the area to cross the canyon.
Scissor lifts are on most typical construction job sites and they’re an often overlooked hazard. Too often, liberties are taken with the lifts that create unsafe conditions, which can cause injuries and deaths. OSHA recently released the results of their investigation of 10 fatalities and 20 injuries involving scissor lifts and released their findings in what the organization refers to as a “Hazard Alert.”
3D printing technology faces major issues when it is required to leave the shelter of a warehouse and step foot on a construction job site. 3D printers are extremely large, heavy, and rely on precise calibration for accuracy. Even the first 3D printed office building in Dubai, which was completed last year, had to actually have its components printed off site and assembled on site. But, Apis Cor, a 3D printing company, believes it has created the technology to print a full structure completely on site.
Road construction is rarely an ideal place for many things. It’s unsafe for workers, it causes traffic issues, and nearby businesses can suffer from it. One more thing can be added to the list, as self-driving cars are also having a hard time navigating construction zones, as well.
Atlanta, GA has been busy recently updated their major sports facilities. The new Atlanta Falcon’s new $1.4 Billion football stadium just recently celebrated a milestone as contractors installed the final roof beam. That stadium is scheduled to open before the start of the 2017 NFL season. Before that, however, the Atlanta Braves’ new baseball stadium will officially open in time to kick off the MLB season, which starts on April 2nd.
The concept of solar roadways has been in the news a lot recently. Using the millions of miles of roadways throughout the world to also create power seems like a no brainer, the asphalt and concrete we’re using now aren’t really accomplishing anything more than handling the traffic on the road. But, there’s also a very strong reason why those products are used: they’re strong, reliable, and relatively durable. Still, many researchers believe there is a lot of unharnessed potential for roads and the world now has a very strong test subject for the future of solar roadways in Tourouvre-au-Perche, France.
With Sears and Kmart stores slowly closing across the country, Sears Holdings had to sell off their longtime brand of tools, Craftsman to generate cash flow. The buyer turned out to be Stanley Black & Decker (SBD), who also runs DeWalt, Black + Decker, Porter Cable, Bostitch, and others. Late last week, their deal to purchase the tool icon was officially finalized.
