Inside a million-square-foot Midtown office tower, renovations are moving forward while business continues uninterrupted. Union contractors and carpenters with the New York City District Council of Carpenters are performing interior renovation work at 520 Madison Avenue, the 43-story tower that serves as the global headquarters of Jefferies Financial Group.

The work spans multiple floors, with union crews performing interior commercial work, floor covering, finish woodwork, furniture installation, and architectural metal and glass work. The renovation also includes an elevator lobby and window treatments throughout the space.

Much of the work is being performed on weekends and outside regular business hours, allowing trading floors and offices to remain operational during the week. With business continuing throughout the renovation, the work has to move forward around the people and operations that keep the building running every day.

Great office buildings never stand still. To remain competitive, New York’s premier office towers must continually evolve to meet the changing expectations of tenants. At 1251 Avenue of the Americas, union contractors and carpenters with the New York City District Council of Carpenters are transforming the 54 story Rockefeller Center office tower as part of a $100 million modernization. The project is creating updated workspaces, modern amenities, and enhanced environments designed to attract and retain leading companies while ensuring the building remains competitive for decades to come.

Their work includes interior commercial systems, acoustical ceilings, floor coverings, finish carpentry, furniture installation, selective demolition, and tenant fit outs throughout the building, all while the Class A office tower remains occupied.

Modernizing occupied office towers takes more than skilled craftsmanship. It takes the planning, coordination, and accountability that union carpenters and contractors bring to every project.

Some environments demand more than a standard build. Union contractors and carpenters with the New York City District Council of Carpenters completed a full-scale renovation at Simpson Thacher & Bartlett’s headquarters at 425 Lexington Avenue, delivering a modernized workplace across multiple floors within the 750,000 square foot tower.

The renovation required precision execution and coordination across every phase of work. Flooring systems, acoustical ceilings, architectural woodwork, and specialty installations were delivered with the consistency expected in high-performance professional environments.

This is what it looks like when experience meets execution. Work completed with care. Teams prepared to perform. Results that hold up under pressure.
