AltaSea at the Port of Los Angeles

Tetra Tech’s High Performance Buildings Group is providing mechanical, electrical, and plumbing (MEP) engineering as well as energy modeling services for Phase 1 of this project, which includes the redevelopment of Berths 56 and 57, and core and shell design of Berths 58, 59, and 60. The facility is pursuing net-positive energy.


  • Size: 35 acres
  • Construction Cost: $185 million
  • Client/Owner: AltaSea
  • Architect: Gensler
  • Completion Date: Phase 1 - 2018


Upon completion of Phase 1 in 2018, AltaSea will be a 35-acre urban ocean-based research facility, located at City Dock #1 at the Port of Los Angeles. This 100-year old City Dock was previously in disrepair and unsuitable for public use. AltaSea will redevelop the dock into a range of facilities, including laboratories, auditoriums, classrooms, businesses, and free open public spaces for visitors to enjoy.

This unprecedented private/public sector project will provide a space for collaboration between the scientific community, higher education facilities, and businesses as they discover innovative solutions to critical marine issues world-wide. AltaSea will also facilitate targeted research on marine- and ocean-related problems, particularly those with a significant socio-economic impact to the Los Angeles area.

Berth 56

A new 25,500-square-foot public interpretive center includes a 150-seat auditorium overlooking the East Channel, 4 exhibit spaces totaling 10,000 square feet, a 1,200-square-foot demonstration lab, a classroom, a gift shop, and State-of-the-art Seawater System for exhibits.

Berth 57

The adaptive reuse of an existing building includes a 39,300-square-foot lab and office, 7,200 square feet of Public Interpretive Space, 2,800-square-foot Public Viewing Catwalk mezzanine, and both 50-seat and 30-seat shared lecture rooms.

Berths 58-60

Each Berth will be 60,000 square feet, will house temporary modular tenant trailers, and tenants will be able to conduct experiments and tests using seawater. These Berths include the design of a new 2,600-square-foot Seawater System Building and Seawater System Infrastructure.
