Specifying flooring that will not be slippery even when it can get wet or otherwise lubricated in use is critical for safety purposes. The 2012 International Building Code (IBC) lays out slip resistance, but there are weaknesses with the requirements—not least of all in that it places a burden on flooring specifiers in particular.

Well-known for its beauty and durability, granite offers numerous design benefits. However, a less familiar advantage is its versatility—particularly when multiple finishes are applied. Today, design teams are selecting one granite type, choosing several finishes, and achieving great variety, texture, and appeal.

Maintaining critical road, rail, and bridge infrastructure

Highway-Application

A recent 60 Minutes episode, “Falling Apart,” noted America’s roads, bridges, airports, and rail lines are outdated, neglected, and need to be fixed. The segment goes on to state, “nearly 70,000 bridges in America—one out of every nine—is considered to be structurally deficient.” Indeed, according to the American Society of Civil Engineers (ASCE), “32 percent of the major roads in America are now in poor condition and in need of major repairs.”

Precast double-tee construction has become a dominant method for building parking garages in North America. The double-tee beam deck system of this construction type provides a finished wearing surface, supports vehicle loading, and forms an integral part of the lateral force-resisting system. However, maintenance and repair of deck connections is a common problem with this type of construction. The most common cause is perhaps the least considered.

Architectural and engineering firms are increasingly exploring stainless steel’s possibilities as a structural material as new research, structural codes, and design guides become available. Most designs have used the familiar Types 304L or 316L alloys from the austenitic family of stainless steels, but for all but the lightest sections, the duplex stainless steel family presents a much greater potential for innovation.
