From Building Things to Building Life: The Engineering Behind Seattle’s Ocean Pavilion

When Seattle’s Alaskan Way Viaduct came down, the city faced a choice about what would define their reimagined waterfront. Their answer? A commitment to conservation, community, and the kind of engineering innovation that turns challenges into opportunities.

The Engineering and Public Works Roadshow takes you behind the scenes of the Seattle Aquarium’s Ocean Pavilion, a project that exemplifies how modern civil engineering has evolved from simply constructing infrastructure to creating spaces that enhance community life and advance environmental stewardship.

Engineering Where Nature Meets the Waterfront

Built on the site of the former double-deck highway, the Ocean Pavilion stands as a statement of Seattle’s values by placing conservation at the heart of the city’s Central Waterfront redevelopment. But transforming reclaimed waterfront land into a world-class aquarium presented unique engineering challenges that required both technical expertise and creative problem-solving.

The foundation work alone told the story of Seattle’s layered history. Engineers drilling for deep foundations in this high seismic zone encountered remnants of the site’s past life including old timber piles and debris from when this land was underwater. Rather than simply fighting the ground conditions, the engineering team adapted their approach, demonstrating the flexibility and ingenuity that defines modern civil engineering practice.

Innovation in Every Detail

The Ocean Pavilion showcases engineering solutions that are as elegant as they are functional. The main exhibit tank, holding 500,000 gallons of water, serves a dual purpose that few visitors would notice – it functions as the building’s primary shear wall, providing critical seismic resistance while creating an immersive experience for guests.

Environmental sustainability is engineered into every system. While most aquariums with access to fresh seawater operate on a flow-through model, the Ocean Pavilion recirculates 96% of its seawater, dramatically reducing energy consumption while maintaining optimal conditions for marine life.

Even the building’s aesthetic choices reflect thoughtful engineering. The structure’s curvilinear form echoes the bluffs of Washington’s coast, clad in heavy cedar timbers that honor the traditions of Coast Salish tribes. The engineering team ensured these materials were sourced from tribal lands, creating economic benefits that extend far beyond the project site.

Connecting Community Through Design

The Ocean Pavilion integrates seamlessly with the city’s broader infrastructure vision. Its rooftop connection to the Overlook Walk, a public pathway linking Pike Place Market to the new waterfront, demonstrates how thoughtful engineering creates connectivity that strengthens communities.

As one engineer featured in the video reflects, civil engineering has transformed over recent decades from “just building things to building life.” The Ocean Pavilion embodies this evolution, creating a gathering space for people at all stages of life and with diverse interests—the very definition of a thriving community.

Beyond Roads and Bridges

For professionals and students considering careers in civil engineering, the Seattle Aquarium project reveals the breadth of opportunities within the field. As one structural engineer shares in the video, she never envisioned working on buildings or aquariums when she entered the profession—she was focused on heavy infrastructure. Yet this project allowed her to experience “the power of engineering” in creating meaningful public experiences.

The message resonates: civil engineers aren’t just the experts behind water systems, roads, and bridges. They’re part of the creative brain trust that brings remarkable community spaces to life—infrastructure that’s visible, valued, and worth celebrating.
