Structural Retrofits & Tenant Improvements

Making Bold Changes Possible: Owner and tenant improvements often go beyond simple finishes or layout changes—they can involve major structural modifications that transform how a building looks, functions, and supports new uses. Whether it’s adding a monumental stair, extending an elevator shaft, removing structural columns, or infilling floors, these changes require careful planning and engineering expertise to protect the integrity of the structure.

Why It’s Important

Significant upgrades like elevator extensions, large architectural stairs, or interior additions can introduce new loads and shift how a building behaves structurally. Removing a column or adding a floor infill may impact the entire load path. Without a thorough structural assessment, these modifications could lead to building damage, performance issues, or even safety hazards. That’s why early involvement from structural engineers is critical to successful—and safe—implementation.

How We Work

At K&H, we help property owners, tenants, and design teams bring transformative ideas to life through smart, code-compliant structural solutions. Our process typically includes:

Review of Proposed Modifications

We evaluate the impact of structural changes—such as stair openings, elevator extensions, or floor infills—on the existing system, looking at load distribution, member capacity, and code compliance.

Coordination with Design Teams

We collaborate with architects and MEP consultants to support the design vision while resolving structural challenges. Our goal is to make bold ideas feasible without compromising safety.

Detailed Structural Design & Documentation

We provide engineered drawings and technical details for all structural elements involved, including framing modifications, new support systems, and reinforcements.

Construction-Phase Support

During construction, we assist with contractor questions, review submittals, and perform site visits to confirm that structural work aligns with our design.

Collaboration & Expertise

K&H works closely with building owners, tenants, architects, and contractors to deliver structural upgrades that support vision and function. With experience across a wide range of building types and renovation scenarios, we bring the insight needed to navigate constraints and uncover practical solutions—without sacrificing ambition.
