Precast concrete panels with Lego-style connections form the building core for team's fast-track rehab of a 4-story Manhattan freight terminal into the tech giant's 12-story NYC headquarters.

The Precast/Prestressed Concrete Institute has recently commissioned the largest Ultra High-Performance Concrete implementation project in which six major precast concrete companies are collaborating to develop their own ultra mixture proportions and to implement the technology.

American Concrete Institute says its first-ever initiative to develop a precast standard is not related to an article in Concrete International that sounds the alarm about the potential for brittle failures of non-code-compliant precast, prestressed-concrete double-T parking decks, with flanges reinforced with a high-strength polymer-coated carbon-fiber grid product, called C-Grid.

The nearly 90-year-old Wolf Creek Bridge is a five-span, reinforced concrete spandrel arch structure measuring nearly 630 ft in length.
