Brazil needs to overcome a very serious situation: complete four World Cup Stadiums in three months. With less than 100 days before the opening ceremony at the 2014 Soccer World Cup, organizers are still optimistic they can complete four stadiums before the opening day. One of the major challenges authorities are facing is because the infrastructure cannot be completed on time and even contractors are working on stadiums on which concrete has not cure yet in order to have everything completed on time. In addition to these challenges, airport facilities and highways are yet to be completed complicating things to World Cup organizer. Brazil authorities are indicating that they are still on track to meet FIFA deadlines.
An international research firm has released a report indicating that the biggest construction trend in the upcoming years is about senior housing. The report from Lux Research indicates that elderly housing could be investing more than double to $127 billion in 2023, an 8% rate increase. All types of healthcare facilities, housing and transportation facilities are changing to accommodate senior citizens needs. New buildings using materials that reduce allergens and infections will drive investments along with natural disaster barriers. The construction of stronger sea walls and levees are projected to soar to a $9 billion business by 2030, according to Lux Research's findings.
A new world record has been set after construction crews poured concrete continuously for at least 20 hours. The concrete pour at the foundation for the tallest building to be constructed west of the Mississippi was verified by an official from Guinness World Records. More than 2,000 concrete truckloads were delivered to the site where a skyscrapper called the New Wilshire will be built. The important record set by 208 concrete trucks delivering 21,000 loads of concrete weighing 82 million pounds. The concrete pour was completed by Sunday noon, establishing the new Guiness Record set previously by 21,000 cubic yards poured at The Venetian hotel in Las Vegas in 1999. To deal with the enormous heat released by the concrete as it sets, a series of chiller pipes were installed at the foundation to dissipate some of the heat released by the chemical reaction. Once finished, the skyscraper will soar 1,100 feet, making it the tallest structure west of the Mississippi. The foundation contains more than 7 million pounds of reinforcing steel. The concrete will take almost two weeks to harden.

The Almeric Christian Federal Building in Golden Rock could become the first federal building to be a zero net-energy building. The federal building is under a retrofit process that includes the installation of a PV system that will generate 100% of the energy used in the court house. A zero net-energy building is designed to produce and conserve all on-site energy so the building will not rely on outer sources to consume energy. The process is being executed as an energy savings performance contract at a total cost of $6 million and performed by Schneider Electric and Dynamic Solar Solutions. The General Services Administration is rolling out an extensive retrofit program at 30 federal buildings that encompasses over 17 million square feet. The program main purpose is to execute over $2 billion on ESCOs over the next couple of years that will reduce energy consumption and generate thousands of jobs. The long-term energy cost savings from the project are estimated to be approximately $13 million over the cost of the contract.

The third longest cable stay bridge in the United States of America is now ready and helping the commute across the Mississippi River. The Stan Musial Memorial Veterans Bridge started construction four years ago at an estimated $229 million and now has become an engineering marvel. The amazing bridge features a main span of 1,500 feet and two back spans of 635 feet. With a total length of 2,770 feet, it will carry four lanes of traffic with an estimated volume of 40,000 cars per day. The new bridge is held in place by more than 3.4 million feet of stay-cable strand secured to two 405-foot-tall A-shaped towers. To support the massive superstructure, footings comprised of six drilled-pier shafts are embedded deep into bedrock.
