Several logistical challenges complicated the design and construction of a radar facility that comprises a tower and an equipment support building at a remote U.S. air base 900 mi inside the Arctic Circle. SGH worked closely with Raytheon,...
Located in harsh marine environments, coastal and waterfront developments require special attention to improve resilience over the project’s design life. Material selection, siting questions, protective coatings, waterproofing detailing, and drainage are all important considerations for the design team.
Abstract: At a remote US air base in northern Greenland, 700 miles inside the Arctic Circle, a Danish Contractor worked with US engineers and US materials to construct a radar tower and supporting equipment building. Problems with site access,...

ABSTRACT
On March 11, 2011 the largest earthquake ever recorded in Japan struck off the coast of the Tohoku region of the country, immediately followed by the one of the largest tsunamis ever recorded. Following these...
Abstract: Sophisticated methods for defense against terrorism have been devised, used, or planned to protect important and exposed facilities of the U.S. government and industry. This paper attempts to expose methods of protection for secondary...

Abstract: On September 11, 2001, an airliner was intentionally crashed into the Pentagon. It struck at the first elevated slab on the west wall, and slid approximately 310ft (94.5m) diagonally into the building. The force of the collision...
Abstract: The Structural Engineering Institute of the American Society of Engineers has formed a Standards Committee to develop a new standard for blast resistant design of buildings. This paper discusses the proposed content of this new document...
