Ocean Pavilion Progress

BROADENING OUR REACH

Since 1977, the Seattle Aquarium has engaged visitors in the wonders of the Salish Sea and Earth’s one ocean. The Aquarium’s 2010 transition from the City of Seattle’s Department of Parks and Recreation to nonprofit management and operation created an opportunity for a new vision. Our 2011–2030 Strategic Plan calls for dramatically increasing the reach of our mission: Inspiring Conservation of Our Marine Environment. In 2014, the Seattle Aquarium began a larger expansion plan as an integral part of the City of Seattle’s waterfront redevelopment project. The Aquarium worked closely with the City of Seattle Office of the Waterfront and the Department of Parks and Recreation on this effort. The planned expansion includes a new building, the Ocean Pavilion; a west-end renovation of Pier 59; a renovation and expansion of Pier 60; and seamless connections to a greatly improved public waterfront. In 2015, the Seattle City Council approved our plan, launching the first phase of our expansion.

Building the Ocean Pavilion

Construction of the Ocean Pavilion began in December 2020, and the building will open in 2024. The project has earned a Progressive Architecture Award and a Build Washington “Excellence in Innovation” award.

In this video, narrated by Seattle Aquarium Senior Director of Capital Projects Susan Bullerdick, see our progress as of September 2023. To learn more about the rooftop project led by Valerie Segrest and Owen Oliver, visit our Honoring Place page.

Explore Ocean Pavilion Construction Phases

Construction of the Ocean Pavilion takes place in four phases. Afterwards, the building will undergo final preparations to ensure that it is ready to welcome animal residents, staff and visitors.

  • Suquamish Tribe land blessing conducted at the site of the future Ocean Pavilion.
  • Site preparation began, including excavation of half of the site, deep soil mixing and adding piping for mechanical, electrical and plumbing systems.
  • East and north exterior walls built.
  • Site preparation continued, including excavation of the other half of the site, ongoing deep soil mixing and completing piping for mechanical, electrical and plumbing systems.
  • Construction of the building’s lowest levels and foundation continued.
  • Ocean Pavilion shell, core and roof constructed.
  • Formwork for habitats completed.
  • Mechanical, electrical, plumbing and animal life support systems installed.
  • Second-floor beams installed.
  • Interior habitats and educational exhibits constructed.
  • Public rooftop constructed with landscaping.
  • Public elevator and stairs constructed.
  • Mechanical, electrical, plumbing and animal life support systems installed (continued).
  • Interior spaces for animal care, education, staff and visitors completed.

Commissioning process

During and following construction, the building will go through a commissioning process. This phase includes preparing the building, habitats and systems for animal residents, staff and visitors prior to opening.

Funding the Ocean Pavilion

The Aquarium’s $160-million comprehensive One Ocean, One Future Campaign is targeting a combination of private philanthropy and government sources. The City of Seattle has contributed $34 million to the project, which will be a City-owned building. Private and public funding efforts continue as we make steady progress toward our campaign goal.

LOOKING AHEAD

The next phase of the Aquarium’s revitalization will focus on its existing buildings and these upcoming milestones:

  • Create a new west end of Pier 59 that reveals stunning views of Puget Sound, expanding our Salish Sea education and conservation programs.
  • Transform Pier 60 into a living habitat for Puget Sound and Washington coast animals, shorebirds and fish.
