Sema Contracting kicked off with a spark of ambition and a big idea: construction could be beautiful, functional, and kind to the earth. Founded by a New Yorker who grew up swinging hammers and dreaming green, we’ve spent over 20 years turning that vision into reality.

Our goal is to build landmarks that stand the test of time, not only as physical structures but as a source of pride for New York—our home, our inspiration, and the heart of everything we do.
