Building Collapse during Construction: Case Study

Currently, I am working on the site supervision for a construction of 20 stories building in a country in SE asia. Last week I did several researches on the technical papers relavant to the building collapse that might occur during the construction to be one of my top priorities in preventing the unsafe work processes and procedures in my site.

I found one of the paper that describes the building collapse during construction. The collapse is due to the soil and foundation unstability problem that was induced by the transported soil from the excavation work.

WTC Collapse : New Scrutiny After Crucial Explosive Dust Samples Found

WTC Collapse Under Fresh Scrutiny After Explosive Dust Samples Found pyroEvidence indicating that the collapse of the World Trade Center was a controlled demolition has been propelled back under the national spotlight following the University of Copenhagen’s announcement that dust obtained from the rubble of the twin towers contains evidence of highly explosive material.

The Earthquake-Proof Building That Is Built to Collapse

The Brilliant Idea: A replaceable, building-wide system to help hospitals, apartment buildings and office towers survive severe seismic shaking.

 Innovators: Gregory Deierlein, Stanford University; Jerome F. Hajjar, Northeastern University

"Elastic high-strength steel cables run down the center of the system’s frame. The cables control the rocking of the building and, when the earthquake is over, pull it back into proper alignment."

"A steel frame situated around a building’s core or along exterior walls offers structural support. The frame’s columns, however, are free to rock up and down within steel shoes secured at the base."

World’s longest tunnel “Gotthard Base Tunnel” : Hot Topic

After two decades’ construction, the Gotthard Base Tunnel in southern Switzerland broke through the final 1.8 meters Friday to create the world’s longest tunnel at 57 kilometers.

Civil Engineering Award for Delhi Metro

The Delhi Metro Rail Corporation(DMRC) has won the Outstanding Civil Engineering Project Award for the year 2010 specially for completing various infrastructural projects in record time, an official said today. The award will be given by the international Asian Civil Engineering Coordinating
Council(ACECC). The council works for the promotion and advancement of the science and practice of civil engineering and related professions for sustainable development in the Asian region.

The award is given to agencies involved in infrastructural projects that have made exemplary contribution to the progress of civil engineering works.

The project taken up by the agency should contribute to the nation where the project is located and they should have impacted on or spread through other Asian nations or ACECC member economies.

Work on a 125-km stretch of the Delhi Metro is in progress in Phase II and will be completed before the Oct 3-14 Commonwealth Games. Large sections of this have already been opened for the public.

Hoover dam bridge finally completed: Hot News

A soaring bridge that will let drivers bypass the Hoover Dam - and steer clear of its security checkpoints and tourists - will open after nearly eight years and £151 million worth of work.
The 1,900ft engineering wonder perched 890ft above the Colorado River is expected to slash travel time along the main route between Las Vegas, Nevada, and Phoenix, Arizona, as motorists will no longer have to make their way across the dam's winding two-lane road at a snail's pace.
