ST PETE PIER, FLORIDA

PAVEMENT AND STRUCTURES

In 2014, the City of St. Petersburg mayor appointed a Pier Working Group to prioritize considerations for a new or renovated pier to replace its 1973 predecessor, a controversial inverted-pyramid building that was unprofitable and underutilized. The requirements included integrating the pier into the city’s downtown waterfront, connecting multimodal transportation options, incorporating environmental and resiliency elements, and adding observation, recreation, and leisure areas. Most importantly, the new local landmark should honor the icon’s 131-year-old history and attract a younger generation as part of a larger 26-acre Pier District redevelopment project.

Argos Portland-limestone cement (PLC) Type IL and  Supplementary cementitious materials (SCMs) were used in most of the concrete mix designs to incorporate environmental and resiliency elements.
