His first posting was in Burundi in the rebel-contested town of Kinyinya. It was 2003 and Ivan Grayton had just started his new job as a logistician with Medecins Sans Frontieres, responsible for the vehicles, communications and the construction and upkeep of the village hospital. Stressful? Yes. Dangerous? Undoubtedly. But no big deal, says Grayton, because as a former tree planter he knew how to cope with adverse conditions and not freak out about it.

Drones, or unmanned aerial vehicles (UAV's), are a boon and a bane as far as Jason Toth and his business partner Derek Heidt are concerned. Toth and Heidt are the principals behind Revered Cinema (RVRD), a BC company that rents out custom-made drones, with cameras and crew, to local and visiting production companies. They shoot aerials for a living and don't like the bad press drones have been attracting.

Builders love old shipping containers. Structurally sound, if not a little ugly, they can be turned into instant structures. Drive-through banks or coffee kiosks come to mind. They’ve even been turned into single family homes. Now, a Vancouver non-profit is going one step further, creating Canada’s first multi-unit housing complex comprised entirely of recycled containers.

In a word, it's not going to happen. That's the view west of the Rockies when it comes to agreeing of a new Softwood Lumber Agreement before the grace period expires October 12. There are just too many significant differences to overcome.

"We build them out of pure laziness," laughs Dave McIntosh about his invention, an air-supported green screen called Airwall. Airwall is a system of inflatable sections that can be arranged to form walls up to 1,000 feet wide 50 feet tall. Drape them in greens, blacks or blues and you an instant VFX backdrop. It's a cheaper and faster alternative to the conventional system of draping fabric over metal frames.

Local is better. At least, that's been the mantra so far. "It's a safe way to keep trees matched to the climate you plant them in," says University of British Columbia Faculty of Forestry professor Dr. Sally Aitken. "They've adapted through the process of natural selection." But climate change is casting doubt on the tried and true. Seedlings that were once well adapted to the environment are showing signs of maladjustment - poor growth and a susceptibility to disease.

Fifty years after its completion, four former workers get together to remember building Cleveland Dam, Canada's largest construction project at the time. This VIDEO excerpt runs 4 minutes.
