American Concrete Institute Recognizes Excellence in Concrete Construction

October 26, 2018 Karli Langner

The American Concrete Institute (ACI) recognized 12 winners at the 2018 Excellence in Concrete Construction Awards Gala during The ACI Concrete Convention and Exposition, October 15, 2018, in Las Vegas, NV.

An independent panel of industry professionals selected winners based on architectural and engineering value, creativity, innovative construction techniques or solutions, innovative use of materials, ingenuity, sustainability, resilience, and functionality.

The awards presentation highlighted project details through short videos that accompanied the presentation of each award.

The evening ended with the presentation of the most prestigious award in the concrete design and construction community, the “Excellence” award.

The overall “Excellence” award winner and first place recipient of the “Infrastructure” category was the Viaduct Over River Almonte – Garrovillas de Alconétar, Cáceres, Extremadura, Spain.

This new high-speed rail line is under construction between Madrid and the Extremadura and will cross over the River Almonte on a 3270 ft long viaduct—a concrete arch bridge with a main span of 1260 ft. Designed to carry 218 mph rail traffic, the viaduct had to meet rigorous dynamic, serviceability, and safety criteria; and it required complex, staged calculations based on nonlinear material and nonlinear geometry behaviors. Nevertheless, it is aerodynamic and slender, largely due to key design features, including a four-legged arch configuration; 11,603 psi high-performance concrete; an efficient erection method, with temporary towers and stays; and an innovative monitoring system.

The ACI Excellence in Concrete Construction Awards were created to honor the visions of the most creative projects in the concrete industry, while providing a platform to recognize concrete innovation, technology, and excellence across the globe. To be eligible for participation in the Excellence Awards, projects needed to be winners at a local ACI Chapter level and submitted by that chapter or chosen by one of ACI’s International Partners.
