With a history spanning more than a half-century in non-combustible commercial construction, cold-formed steel (CFS) is a popular material choice for framing non-structural interior walls, load-bearing interior and exterior walls, curtain walls, and floor joists. Its many performance-based characteristics and ‘green’ attributes have enabled architects to design safe, durable structures that are both dynamic and sustainable.

Defining and Refining Polished Concrete

Hiperfloor premium reflectiveHC550-0142

French-American architect Paul Philippe Cret once said, “Of the many doorways we pass in a short walk, most are fulfilling their purpose, most of them are well-enough built. [But] how many are worth a second look?” Cannot the same be said about architectural polished concrete? Are your floors meeting your design intent or did you settle? Do you know how to distinguish between the floor you asked for, and the floor being presented to you during the punch list?

Energy distributor makes efficiency top priority

By Kevin Hutchings

Maximizing energy efficiency is a key concern on virtually every new commercial construction project. When the construction happens to be for the electric provider itself, it is easy to understand how the priority takes on even greater importance. This was the case for Washington Electric Cooperative, an energy distributor located in Marietta, Ohio.

The company had been operating for years out of three separate …

Over the past several decades, the confluence of value engineering and sustainable design has enabled construction of better, more efficient buildings. Both trends play crucial roles in realizing the quality, durability, and longevity of the built environment. Often, value engineering and sustainable design can identify the best material for the application and install it in the most efficient way possible. Such careful consideration of materials and processes generally results in less waste, accurate use of material, and efficient use of resources and manpower.
