Oregon State University has completed a major transformation of its 1950s-era Cordley Hall into a modern research and academic facility through a $147 million renovation project finished in April 2024.

Led by Andersen Construction and designed by Hennebery Eddy Architects, the 220,000-square-foot overhaul introduced advanced biology labs, a 220-seat lecture hall, and flexible research spaces — all while keeping the building partially operational throughout construction.

“This project is a strategic investment in our infrastructure,” OSU officials said, highlighting the renovation’s $45 million reduction in deferred maintenance.

The phased renovation — split into East and West wings — improved seismic safety, accessibility, and building systems. Modernizations included new electrical and mechanical systems with standby power, updated fire protection, and a revitalized courtyard by artist Ann Hamilton, whose DNA-embossed pavers symbolize a universal biological connection.

Energy efficiency was a major priority. A new 5,816-square-foot District Utility Plant now supports Cordley Hall and five nearby buildings. This centralized cooling system has already lowered energy use by 36% below code and saves about $150,000 annually in energy costs.

“We’ve found this approach provides long-term value while preserving the campus’s architectural character,” said project team members. Instead of demolishing the building, OSU maintained the structure’s bones and reached LEED Gold equivalency through sustainable development practices.

Cordley Hall continues to house the Integrative Biology and Botany and Plant Pathology departments, supporting over 1,100 students annually and now providing enhanced public access to the Herbarium and Oregon State Arthropod Collection, totaling more than 3.5 million specimens.

The project utilized Building Information Modeling (BIM), chilled beam technology for energy-efficient cooling, and fiber-reinforced materials to boost resilience. Apprenticeship participation reached 26%, with 22% of hours from minority workers and 5% from women — exceeding the 15% apprenticeship goal.

“We’re proud of how this project balances cutting-edge infrastructure, sustainability, and inclusivity,” said representatives from Andersen Construction.

Key players in the planning included OSU’s departments of Biology, Finance, Design & Construction, and the College of Agricultural Sciences. The project was funded through multiple sources:

• State of Oregon: $104 million
• OSU: $55 million
• Grants: $10.5 million

Subcontractors such as Black Line Glazing, Fought & Co., McKinstry, Otis, and R3 Engraving and Signs helped bring the renovation to life, ensuring every detail met the technical and sustainable ambitions of the university.

With this transformation, Cordley Hall now serves as a model for how universities can adapt historic buildings to 21st-century scientific and environmental needs.
