During construction of a new baseball stadium, site constraints made it clear that the visitors’ clubhouse would not be easily accessible from the dugout. Consulting engineers CS Davidson needed to consider affordable options for an underground tunnel, since one of the largest obstacles facing the project was meeting strict budget constraints.

“We had to value-engineer wherever we could and look at every alternative available,” said Thomas Englerth, Land Development and Survey Department Manager for CS Davidson.

After comparing masonry walls, precast concrete and cast-in-place concrete options, CS Davidson chose Contech’s Structural Plate products. They found a 12-gauge MULTI-PLATE underpass to be the most cost-effective solution. Inside the structure, a concrete sidewalk, handrails and lighting finish the visiting players’ walkway.

Another significant challenge was incorporating three horizontal elbows into the design of the structure. The soil side of the structure was also covered with a ten-ounce fabric and PVC liner to prevent infiltration. Sub-contractor Silverbridge, Inc. completed assembly of the structure in just five days, and Empire Services, Inc. installed it successfully at the site.
