The vehicle took out a sprinkler pipe at the Harristown Road building off Lincoln Avenue Monday morning.
"At least my truck is getting washed,” the driver told a responding police officer.
The driver delivered packages while a tow truck operator and police let the air out of the van's tires -- but that wasn't enough.
All four wheels had to be removed using two tow trucks.
Borough firefighters also responded, along with a building inspector. Another FedEx truck picked up the remaining packages for delivery.
The building didn't appear structurally damaged.
