Here's proof that construction workers aren't just tough guys.

A group of iron workers in Long Island, New York, painted "get well" messages on steel beams to cheer up the children who could see them from their windows at the hospital they were working alongside.

Iron workers building the new Stony Brook Children's Hospital wrote inspiring messages for the young patients next door, at the existing hospital.

"It's remarkably touching," Dr. Ken Kaushansky, dean of Stony Brook University School of Medicine, told TODAY.com.

He explained that construction is underway next to the existing facility for a new children's hospital. The first message was written by a worker whose child was a patient at the hospital, and who then responded by writing a "thank you" note and putting it in her window, he said.

The 'get well' messages were inspired by workers whose own children were patients at the hospital.

That prompted a second message from the iron workers, this time sending well wishes to all the patients at the hospital. The messages went up right before the hospital held a "topping off" ceremony on July 24, to celebrate the final beam being installed for the soon-to-be Stony Brook Children's Hospital, a multimillion-dollar expansion for pediatrics.

"Unfortunately, when we finish the building, we won't be able to see them," Dr. Kaushansky pointed out, adding that for now, the messages are a sign of hope for kids in the hospital. The beams on which the messages were written face the pediatric floor in the existing hospital.

In response to the messages, at least one 'thank you' from a patient appeared in the window.

Mark Swanson of The LiRo Group, a construction company in Long Island that's managing the hospital project, said he had no idea the workers were going to write the messages.

"It was just a really nice surprise for everybody," he said. "It's one of those things where it kind of took on a life of its own."

The messages urged patients at the Long Island, New York, hospital to get well soon.

"People of course have preconceived notions that construction workers are just hard-nosed and a bunch of tough guys," Swanson added. "But I think this goes to show they're really just a bunch of softies. Especially when it comes to sick children."
