Every February since 2009, the winner of the Times Square Arts Love & Design Competition takes its temporary place in Duffy Square. Silman has collaborated with many project designers to engineer support structures for the hearts and verify their stability. In 2023, Silman provided structural consulting services for designer Almost Studio and fabricator Arcana on an artificial garden consisting of four heart-shaped hedge rows.
In 2021, Silman collaborated with Soft–Firm on Love Letters. Resembling two interconnected hearts in plan, the installation uses a single undulating plywood surface to create four distinct spaces. Silman found that the structure of this installation was sufficient for temporary display and capable of supporting its self-weight as well as winds up to 98 mph within code-prescribed limits for stress and deflection. The firm’s engineers also worked with the architect and fabricator to develop a base and ballast system congruent with these analyses.
