The last piece of steel was recently put in place at the top of the soon-to-be 836-foot-tall tower after a ceremony at the base of the building, involving the people who developed, designed, and are building the skyscraper.  In traditional fashion, everyone got a chance to sign a 28-foot-long girder before it was hoisted into place.  The building topped out in January of this year.

One Bennett Park is slated to become Chicago’s tallest all-residential building when it opens in 2019.  It will have 69 luxury condominiums on its upper floors, and 279 rental apartments below.  The building was designed by Robert A.M. Stern Architects in New York for River North’s Related Midwest, with Michael Van Valkenburgh Associates landscaping the adjacent park, and Lendlease performing duties as general contractor.

Related Midwest Marks Installation of Final Steel Beam at One Bennett Park in Downtown Chicago

Placement of 28-foot, 2,856-pound beam marks the completion of structural steel work at Robert A.M. Stern-designed high-rise, slated to be Chicago’s tallest all-residential tower

CHICAGO – Developer Related Midwest and general contractor Lendlease this week marked the completion of structural steel work at One Bennett Park, Related’s ultra-luxury residential development at 451 E. Grand Ave. in Chicago’s Streeterville neighborhood. Designed by Robert A.M. Stern Architects, with an adjacent park by Michael Van Valkenburgh Associates, it is slated to be Chicago’s tallest all-residential tower when completed in 2019.

Senior executives, project managers and construction teams from each firm, along with union tradesmen and tradeswomen who labored on the project, gathered on April 30 to sign and hoist the final steel beam – a 28-foot, 2,856-pound girder topped by the American flag – before it was hoisted into its final position.

“The placement of the final steel beam in One Bennett Park brings us one step closer to completing what will be downtown Chicago’s premier legacy address,” said Curt Bailey, president of Related Midwest. “Throughout the planning and construction process, we have worked with the best and brightest in the industry to ensure no detail is overlooked. Thanks to the collective efforts of our partners, One Bennett Park will stand out as the latest addition to an elite group of Chicago skyscrapers whose timeless designs have earned international recognition.”

“No tall building designed in classical tradition is complete without its crown,” said Daniel Lobitz, partner at RAMSA. “One Bennett Park meets the skyline with asymmetrical composition, juxtaposing a rectangular volume punctuated by four-story masonry piers and a square pavilion with notched corners and colossal 30-foot-tall windows. These elements complement Chicago’s illustrious forebears like the iconic Wrigley Building and Tribune Tower.”

Under construction since February 2016, One Bennett Park is scheduled to be fully complete in mid-2019, with the first apartment residences delivering in late 2018 and condominiums beginning in early 2019. The building will feature a total of 69 condominium residences located on floors 41 through 66, with a choice of two-, three- and four-bedroom plans averaging 3,200 square feet. Owners will have access to an exclusive amenity floor on level 41, as well as their own private lobby on the lower level with a motor court and 24/7 valet parking. Related Midwest is currently offering a selection of condominiums ranging in size from 1,737 to 7,500 square feet and priced from $2 million.

“On this day, we honor the thousands of construction professionals, tradesmen and tradeswomen who continue to work tirelessly to bring this project to fruition,” said Don Biernacki, senior vice president of construction at Related Midwest. “While we are excited to add a premier residential tower like One Bennett Park to the Chicago skyline, we are equally proud to have created jobs for the city and the Streeterville community. We thank each and every contributor to this project as we continue to work toward completion.”

“The collaboration and dedication the tradesmen and tradeswomen have brought to this iconic project reminds me why this industry inspires greatness,” said Bert Brandt, senior vice president and general manager of Lendlease. “Countless hours have gone into making One Bennett Park what it is, and Lendlease is proud to be partnering with Related Midwest to see it to completion.”
