Two LEO A DALY Projects Earn BD+C 2024 Innovation Spotlight

Carson Group and 20 Mass Make the Top 40 Great Solutions Report

Each year Building Design + Construction editors analyze hundreds of submissions to select 40 Great Solutions to publish nationally. 

The Great Solutions featured in this year’s BD+C roundup have exceptional characteristics that benefit clients/owners, building occupants and the broad market of development, design and construction. LEO A DALY earned two spots on the 2024 list.

“Both projects demonstrate the innovative results of collaborative partnerships combined with our comprehensive service capabilities,” shares LEO A DALY President, Steve Lichtenberger. “We aim to leave a sustainable signature by delivering visionary architecture with world-class occupant experience through highly refined engineering.”

The Carson Group Headquarters post-occupancy evaluation validates the buildings’ innovative shell and building system design. The smart glass responds to changing concentrations of daylight to control heat gain and glare, and all building systems were designed in concert with the SageGlass envelope to maximize occupant comfort.

20 Massachusetts Avenue models a responsible placemaking design solution that restitches the urban fabric and now serves as a prominent anchor in Capitol Hill and Washington, D.C. The design implemented creative modular construction with curated components prefabricated off-site which reduced waste by 50% and saved considerable cost and time.
