Sitting in an industrial wasteland that was once the local hub of Kodak, a four-storey industrial building is being picked up this morning and moved 60 metres to make way for a new LRT station at the corner of Eglinton Avenue West between Black Creek Drive and Weston Road.

"It's a very complex engineering challenge obviously," said Jamie Robinson with transit agency Metrolinx.

So how's it done?

First, hydraulics are used to lift the building. Then it's put on steel girders, lowered onto a set of 24 dollies (eight powered) and rolled away along special rails. Once it's moving, the building will travel at a rate of 16 inches (40 centimetres) a minute.

The community wanted the building — which once served as a recreation centre for Kodak employees — to be spared and made part of the new Mount Dennis station on the Eglinton-Crosstown light-rail line. Metrolinx agreed and so the building will be moved back later in the construction process to form part of the new station's entrance.

Here's how CBC's Linda Ward followed what's being called "the big move" on Twitter:

They'll lay new foundation, then move it back into place to be incorporated into LRT Mt. Dennis station design <a href="https://t.co/Mrnf9QVH7h">pic.twitter.com/Mrnf9QVH7h</a> —@LindaWardCBC

It IS moving. Look for the green hose on the fence in both pics! <a href="https://t.co/BAV9V8Z8oK">pic.twitter.com/BAV9V8Z8oK</a> —@LindaWardCBC

Slowly but surely...the building is almost done it's 60m journey! See the green hose on the fence then and now... <a href="https://t.co/yHEAz4vthV">pic.twitter.com/yHEAz4vthV</a> —@LindaWardCBC
