A Calgary construction worker is in hospital after falling two to three metres down a concrete manhole.

Shortly before noon Wednesday, the Calgary fire department was called to Aspen Hills Green, a new community off 17th Avenue and 85th Street S.W.

The worker, a 27-year-old man, had fallen into an uncovered manhole at a construction site.

Fire and EMS treated the man where he was until firefighters were able to remove him with a basket-type stretcher within less than 10 minutes of their arrival on site.

EMS spokesman Adam Loria said getting the man out wasn't easy.

"It was a difficult manoeuvre and area to work … there's a lot of dirt and gravel and such. But again we all pulled together, worked hard, [and] we did extricate him there in a timely fashion," Loria said.

The man was taken to hospital and is now in stable, non-life threatening condition.
