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?

Built in the late 1920s, the Art Deco 10 Light Street is the first skyscraper in Baltimore. A detailed façade inspection was recently completed using 29 swing stage drops for close access—this led to a restoration project for the more than 325 m2 (3500 sf) of Italian marble, replacing it with a durable quartzite from Brazil. This article examines what occurred during the reconstruction.

When there is a tile or stone failure, a contributing factor is often the lack of properly installed movement joints. Just like concrete sidewalks and bridges, tile and stone need to have movement joints to control the anticipated movements within a structure. Tile and stone will expand and contract when it is subjected to heat/cold or moisture/dryness. It is critical for architects to properly specify the design, materials, and layouts of movement joints.
