Michael Heaner and Grant Greenspan of Kaufman represented Adler, while Jamie Katcher of Cushman & Wakefield represented the engineering firm. Kaufman serves as the exclusive leasing agent.

Although tech firms are replacing the neighborhood’s historic fashion tenants, several other offices at 550 Seventh Avenue continue to house the latter. Lifestyle brands there include Badgley Mischka, Ralph Lauren, Donna Karen and Lily Pulitzer, the release said. – Mark Maurer
