Solid timber, solid construction performance

Forte_Credited

Solid timber construction, sometimes called ‘mass timber,’ is an emerging set of engineered wood products—massive planar or frame elements used for walls, floors, roofs, partitions, and core elements of a building. As shown in Figure 1, examples include both glued configurations liked glued-laminated timber (glulam), structural composite lumber (SCL), and cross-laminated timber (CLT), as well as non-glued products like dowel-laminated timber (DLT); nail-laminated timber (NLT), cross-nail-laminated timber (CNLT), and interlocking cross-laminated timber (ICLT).

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A recent 60 Minutes episode, “Falling Apart,” noted America’s roads, bridges, airports, and rail lines are outdated, neglected, and need to be fixed.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.”

Specifying architectural zinc

Zinc-Roof-Castle-Miramare

Architectural zinc (titanium-zinc alloy, rolled zinc, zinc strip) is a soft, natural-weathering metal that has been used for centuries in various roof applications. Its value reaches far beyond beauty and durability. Following ‘zinc-appropriate’ design, a quality metal roof specification will not follow a standard painted metal specification, but instead cover issues unique to this material. In some cases, prescriptive requirements for the material quality, technical support, panel profile, installer qualifications, and detail quality will be necessary.
