Structural Engineering
We create buildings that reflect vision and serve communities - built on strength, shaped by trust.

Structural engineering is the art and science of making architecture stand, endure and inspire. It’s not just about resisting loads or meeting code - it’s about unlocking possibilities.
We believe structure is integral to design. It can be a bold statement or the quiet confidence of a space. Whether exposed or hidden, structure tells a story of strength, precision and intention.
Our team approaches every project with curiosity, creativity and technical excellence. From complex landmarks to understated spaces, we collaborate closely with architects, owners and builders to shape structures that perform and inspire. We don’t just solve problems – we anticipate them, adapt quickly and engineer with clarity and care.
New Structures
The framework supporting how people live, work, gather and connect.
new structures

Structural engineering is more than simply what holds a building up.
Structure can be celebrated or subdued as the designer desires. It demonstrates confidence in strength and efficiency. It can be what catches the eye to some and goes unnoticed by others. Done well, it’s both a feature and unseen.

Existing Structures
Honoring the past by breathing new life into the present.
existing structures

Existing buildings are more than a hollow shell. They have a soul to be celebrated.
They present a special challenge, to find a way to use what’s existing and modify it to current regulations. We have a long history of breathing life into buildings long thought dead.

Forensic Engineering and Disaster Response
Providing assistance in times of emergency.
forensic and disaster response

When disaster strikes, Wallace Design Collective provides rapid, reliable expertise to help communities, owners and insurers recover with confidence. Our forensic engineers assess damage caused by natural disasters, structural failures, accidents and other unexpected events. We work quickly to evaluate conditions, determine the root cause of problems and provide clear, actionable recommendations for repair or remediation.
We’ve been involved with inspections of buildings damaged by earthquakes, tornadoes, hurricanes, storms, heavy snowfall, foundation problems and landslides. We understand the urgency of these situations. Our engineers promptly assess the damage, identify potential hazards and recommend solutions, prioritizing the safety of occupants and the overall integrity of the structure.
By combining deep structural and civil engineering expertise with a practical understanding of construction and materials, Wallace helps clients make informed decisions in the most challenging circumstances.
Components and Delegated Design
Designing the pieces that make buildings work.
components and delegated design

Wallace Design Collective partners with manufacturers, fabricators and contractors to deliver safe, efficient and cost-effective structural solutions for components and delegated design systems. Our engineers are trusted to design specialty elements such as precast and tilt-up panels, steel connections, cold-formed metal framing and other critical building components.
By combining a deep understanding of structural behavior with practical knowledge of construction, we provide solutions that integrate seamlessly into the overall project while meeting code and performance requirements. Our responsive approach provides clear communication, quick turnaround and coordination that supports both the design team and the construction schedule.
From local sites to national ventures, we deliver structural solutions that combine expertise, innovation and lasting performance.
