REDWOOD CITY, CA -- (May 27, 2010) -- Rudolph and Sletten, a wholly owned subsidiary of Tutor Perini Corporation (NYSE:TPC), announced today that the company has been chosen to build NOAA Fisheries Services Southwest Fisheries Science Center (SWFSC) in La Jolla, California. The 240,000 square-foot project which includes underground facility parking for up to 202 vehicles, is funded with part of the $830 million NOAA received from the American Recovery and Reinvestment Act economic stimulus package, replaces an older facility that is precariously perched on the edge of a 200-foot cliff. Construction will begin next month.

NOAA’s new SWFSC will perform research for the organization’s National Marine Fisheries Service and will contain a large seawater and freshwater Ocean Technology Development Tank used to study and survey fishery resources and ecosystems. The facility will contain an experimental aquarium, a large animal necropsy lab, a specimen processing lab, a photogrammetry lab, an ichthyoplankton lab, genetic labs, physiology labs, oceanographic labs, specimen archives, electronic workshops and a large tank for testing new sampling technologies, plus a library, conference rooms and office space for up to 300 scientists and support staff. The building will also house the world’s largest collections of California Current ichthyoplankton and tissue samples for marine mammal and marine turtle genetics.

“Laboratories have been a specialty of Rudolph and Sletten since the early days of biotech in the Bay Area. Add to that our long-standing relationship and experience with the Monterey Bay Aquarium and this project with NOAA becomes a perfect fit for our capabilities,” said Martin Sisemore, Rudolph and Sletten, CEO and President. “In addition, this project adds to our growing list or government-funded and economic stimulus-supported projects.”

When the science center is completed in 2011, the facility is targeted to be LEED Gold certified. NOAA is pursuing certification of the building under the Leadership in Energy and Environmental Design (LEED) Green Building Rating System. The green design of the new laboratory includes photovoltaic cells, elaborate water retention systems, recycled materials and green roofs planted with California coastal chaparral.

The architect of record is Gould Evans of Kansas City, Missouri, and the associate architects are Architects Delawie Wilkes Rodrigues Barker of San Diego. Based on the design work alone, the project has already received a top award from the American Institute of Architects (AIA), rare for a project not yet built.

NOAA Fisheries Service’s Southwest Fisheries Science Center integrates policy expertise and cutting-edge scientific research to provide management and conservation of domestic and international living marine resources. Established in 1964 to study and manage the sardine and tuna fisheries of the U.S. West Coast, the SWFSC provides scientific advice, manages fisheries and conserves protected species along the U.S. West Coast, throughout the Pacific Ocean and in the Southern Ocean off Antarctica.

Rudolph and Sletten’s building expertise includes virtually all types of projects with an emphasis on those markets where their technical expertise and quality excel: biotech and pharmaceutical; healthcare; and technology. Other areas of expertise include commercial office and corporate campuses, education, gaming and hospitality, government, sports and entertainment and industrial facilities. Rudolph and Sletten’s current clients include Hewlett-Packard, Genentech, Kaiser Permanente, Stanford University, the Monterey Bay Aquarium, Johnson & Johnson, Agilent Technologies, and the UC and CSU University systems.
