A building on Colorado State University’s campus remains closed after a frozen pipe burst. The B and C wings of the Clark Building, that’s home to offices and classrooms, have been shuttered as crews work to clean up flooding from frozen fan coils that burst in last week’s arctic blast. CSU facilities management discovered the damage to Clark Saturday night. Other buildings like the student rec center, the Biology building, the Lory Student Center, and Canvas Stadium also saw frozen pipes, but damage didn’t necessitate a closure.
