Asphalt recycling process gaining in popularity at construction sites
St. Louis Post-Dispatch via Engineering News-Record
Recycling old asphalt from roads and parking lots is an old idea that is gaining new traction. Interest is growing in a recycling process that uses broken-up old asphalt as a base for new asphalt roads and lots. The process is called full-depth reclamation, and it's been around for decades. More

This concrete-eating robot can recycle an entire building on the spot
Fast Company
Knocking down a concrete building usually takes brute force: Wrecking balls, huge excavators, or explosives rip apart walls while fire hoses spray water to keep the clouds of dust down. It's an energy-intensive process, and after everything's been torn apart, the concrete often ends up in a landfill or has to be trucked to a recycling facility.More

St. Louis Post-Dispatch via Engineering News-Record
Recycling old asphalt from roads and parking lots is an old idea that is gaining new traction. Interest is growing in a recycling process that uses broken-up old asphalt as a base for new asphalt roads and lots. The process is called full-depth reclamation, and it's been around for decades. Now, the process is growing in popularity among businesses, road districts and transportation departments because it usually saves costs over hauling away the old asphalt that is being replaced. And some officials are becoming convinced that the base created by using old asphalt is solid and durable.More

P3 projects: What if you have payment problems?
By Scott Wolfe
Public-private partnership construction projects — commonly referred to as P3 projects — are becoming popular in the construction industry quickly. In fact, President Barack Obama recently took steps to expand the market for P3 transportation projects. This, along with the ordinary national trends, means that you're likely to encounter a P3 project soon. While the underlying construction tasks performed will be the same on a P3 project, the regulations, contractual obligations and legal rights available to you may be different — and, unfortunately, unfamiliar.

Demolition starts at Boeing 777X wing plant site
Puget Sound Business Journal
Eleven sledgehammer-wielding leaders launched construction of the Boeing 777X wing plant Aug. 13 in Everett, Washington, by smashing holes into one of three buildings that are to be demolished to make way for the new building. The ceremonial event attracted an array of Boeing, union and government leaders, including Gov. Jay Inslee and Sen. Maria Cantwell. Both said Boeing's decision to build the re-engined and rewinged 777X in Washington is crucial for the future of aerospace in Washington.More

Construction industry missing key tool: Skilled workers
It's a beautiful day and Jeremy Smith, the business manager for a school district in northern Wyoming, is showing off the new Tongue River Elementary School — or at least the plot of land where the school should be. The school was supposed to be under construction by now, but last month state officials said they didn't have the money. The district sought to keep costs down by borrowing the design for its new school from one that had been built last year in a nearby town.
"[That school] was built for about $211 a square foot," Smith says. "When we opened bids on the same school it was [$280]." In other words, the new Tongue River would cost 33 percent more than the same school design did last year, just 30 miles away. It's a problem of supply and demand: There is a massive construction boom right now but construction workers are few and far between.More

Cha-ching! Florida workers find 2,000 silver coins during home demolition
Yahoo News
Police in Florida have seized 60 pounds of silver coins that had been stashed for decades inside the walls of a recently demolished home. According to officials in St. Cloud, Florida, glass pickle jars holding more than 2,000 coins shattered while city workers were leveling a 1915 bungalow, turning the demolition into a momentary slot machine. "It was like a treasure hunt — the more you dug the more you found," one of those workers, Melissa Howes, told the Orlando Sentinel. "We thought we might be able to keep it like finders keepers, but it was city property."More

High bids stall preservation of historic bridge in Minnesota
Mankato Free Press
The long journey by Blue Earth County, Minnesota, residents, historical preservation groups and state transportation officials to preserve the 113-year-old Dodd Ford Bridge in Mankato appeared to be nearing its completion until Aug. 12, when high construction bids threw a last-minute roadblock in front of the project. "Anything good takes a little longer to get done," said County Commissioner Drew Campbell as the board unanimously rejected bids to repair and reopen a bridge that was once on the list of Minnesota's most endangered historic structures.More
