Construction is underway on a 1.5-kilometer long ice wall surrounding the Fukushima Nuclear Plant in Japan. The ice wall will prevent ground water flowing from nearby hills from mixing with the polluted soil beneath the nuclear plant. It is estimated that 400 tons of groundwater passes underneath the reactor’s basement each day. The chemicals used to cool the reactor have seeped through cracks into the basement walls and pipes and have contaminated the soil. The project, which began on Monday, will be completed in March 2015. The Japanese government is funding the project, which is expected to cost $313 million to construct. The owner and operator of the plant, Tokyo Electric Power, will conduct several months of testing on the ice wall once it is completed to ensure that it is working properly.  Tokyo Electric Power plans to maintain the ice wall for over a hundred years.

Cylinder molds weight little but take up space, therefore shipping costs are expensive, commonly leading you to have large orders of cylinder molds shipped by truck. But what if you need extra molds and cannot afford to wait?  

Humboldt's new product is here to solve the problem!

There is an app in the Apple App Store that allows users of all ages and experience level, play the role of a structural engineer. TrussMe!, created by Scientific Monkey, provides players with a load and several structural members. The user must design a truss to support the load using the supplied members and supports.  Each member has a different cross sectional area, and thus a different weight.

New York Tomorrow Skyscraper Proposal

New York Tomorrow, submitted by architects from the firm Fundamental, recently received runner-up honors in Metropolis Magazine’s Living Cities Competition.  The magazine’s competition is open to students and professionals and calls for proposals for multi-use residential towers for the 21st century. The building lot for New York Tomorrow is located on East 68th Street in New York City. The design overcomes the lot’s small site size (18 by 70 feet) by cantilevering the tower’s lobby out over a neighboring building. The design relies on revolutionary structural design technology and a unique multi-purpose space to draw in potential residents.

A decade after the identification of potentially vulnerable concrete school buildings across the state of California, a new report published by UC Berkeley based Pacific Earthquake Engineering Research Center (PEER) brings attention back to the older concrete LA buildings. The list contains 1,454 buildings, including schools, offices, theaters, churches and many residential buildings. 

The Willis Tower Skydeck is one of the most popular and unique tourist attractions in Chicago. The Skydeck features four boxes known as The Ledge that allows visitors to step outside of the Willis Tower and look down at the street below. The view of the city from 1,353 feet is fantastic, and on a clear day one can see as far as the Wisconsin border. While the first steps onto The Ledge are scary and exciting at the same time, one California family had a bigger scare than usual when they first experienced the Ledge.
