Miami's first supertall skyscraper, Waldorf Astoria Hotel& Residences, makes significant progress on foundation work with record 190-foot deep auger cast piles

Foundation work at 300 Biscayne Boulevard, home to the upcoming Waldorf Astoria Hotel & Residences, has reached a major milestone. This 100-story supertall tower, designed by Sieger Suarez Architects in collaboration with Carlos Ott, aims to redefine the downtown Miami skyline. Developed by Property Markets Group, Greybrook Realty Partners, Mohari Hospitality, S2 Development, and Hilton, the 1,049-foot-tall building will be the tallest in Miami, encompassing 1,738,999 square feet.

Recent photos from Andres Baquerizo at Keller, the contractor responsible for site work and foundations, showcase significant progress, including extensive soil mixing and the installation of 190-foot deep Augercast/CFA piles, setting a record for the tower's foundation. The next steps will involve forming pile caps to distribute the load evenly, followed by pouring a substantial mat foundation to prepare for vertical construction. The Miami Building Department granted a Full Vertical permit in January, with construction projected to be completed in 2027.
