Lumen LIC
A 66-story tower in Long Island City, Lumen LIC incorporates 600 residential units above retail and office space in an 855,400 SF cast-in-place concrete structure.
With a slenderness ratio of 10:1 in the narrow direction, overturning and wind-induced displacement presented primary structural design challenges. DeSimone increased lateral stiffness by introducing a concrete outrigger and belt wall system at the 39th and 40th floors, transferring loads between perimeter columns and the central core. The lateral system utilizes high-strength concrete with reinforcement and couplers to manage both wind and gravity forces.

The tower’s foundation comprises caissons socketed into bedrock, each capable of supporting up to 1,000 tons. Below-grade parking required column transfers using 10-foot-deep reinforced concrete girders to preserve program without sacrificing performance. Floor-to-ceiling windows and a reflective curtain wall are structurally integrated and designed to accommodate thermal movement and lateral pressures.
Self-consolidating concrete allowed for efficient high-rise placement and finish quality. Throughout the structure, we refined concrete frame strategies using lateral analysis models to minimize steel demand while meeting stringent drift and zoning constraints. The project targets Two Green Globes certification with passive solar design, high-performance glazing, and a concrete-supported landscaped terrace.
