Made in Germany at the U.S. Department of Defense
Quite appropriate: The world's mightiest military force is commanded from the world's "mightiest" office building. The U.S. Department of Defense has been located in the Pentagon since 1943. The headquarters complex sits on the shore of the Potomac River in Washington, D.C. The various Defense Department offices were previously spread rather inefficiently all around the U.S. capital.
Each of the Pentagon's five exterior facades is more than 300 yards in length. Some 17 miles of corridors link the numerous offices covering a total area of more than 3,700,000 square feet. Thanks to the highly efficient design, it is possible to get from one location within the complex to any other in a maximum of just under eight minutes.
Updating such a complex entails substantial expenditure in terms of both time and cost. Between 1994 and 2011, the Pentagon underwent a complete renovation costing $5.3 billion. Quality and cost-effectiveness were the top priorities on the prestigious project. After intensive testing, the product chosen for the sanitary and heating installations was Viega's highly durable and economical copper piping system ProPress.
Marv Wheeler from installation contractor Southland Industries cites a number of other points in favor of ProPress alongside its durability: "The press connection technology means the pipe connections are much tighter and more secure than soldered connections. And pressing cut the installation time literally by half."
With nearly 28 miles of piping, that was a key factor. Traditionally in the U.S., copper pipes were soldered, but once ProPress was introduced to the American market and users began to see the big benefits, press technology has become increasingly popular.
