Scattered rain didn’t stop the University of Delaware from raising the final beam into place for its $165 million new Building X Thursday evening.
Imagined as a hub for science research and classes, the building is on track to be completed and open to the public in fall 2024.
The ceremony ended up getting downsized because of rain and because dignitaries expected to attend were caught in traffic.
The building will be four stories and 132,000-square-feet with themes of mind, brain and behavior; models and mechanisms of human disease; and quantum science and technology.
Most of the technological work will take place in the basement, while the upper floors will mainly consist of a mix between life sciences and neurosciences work.
Construction started in February 2022 when the school demolished the McKinley Lab, which was built in the 1970s. A 2017 fire had severely damaged the McKinley lab beyond repair.
MORE ABOUT BUILDING X: UD’s Building X aims to drive research, cutting-edge learning
Building X will be the newest addition to UD’s 15 core research facilities. They share instrumentation that’s used by many different kinds of scientists.
The new building will serve as a workspace for 48 research scientists and will welcome more than 1,000 students per year in its four teaching labs.
Funding came from university funds and the $41 million the university received through the Federal American Rescue Plan Act, which was pandemic relief money.
John Pelesko, former dean of the College of Arts and Sciences and head of Building X’s planning team, has said that Building X will be a nucleus for neuroscience research, specifically with studying models, treatments and mechanisms of human disease.
The building will act as a focal point for quantum science and technology in a time Pelesko called the “next quantum revolution.”
Quantum science explores the physical properties of nature at the scale of atoms and subatomic particles, often in relation to energy.
Some of the practical applications of quantum science are creating MRI scanners, lasers, fluorescent lights, solar cells and more.
