The frost generated by Canadian winters wreak havoc on structures through their foundations. According to code conventional foundations and footings must rest below the reach of frost on undisturbed soil (in most provinces, this is safely considered to be 4 ft. below ground level or grade), bear directly on bedrock, or be frost-protected. A shallow foundation may be possible in your area in an outbuilding if you can get an engineer to design and stamp plans for insulating the area directly beside your shallow foundation wall so that frost will not form beneath the footing area and cause damage. A slab-on-grade foundation for an outbuilding is another option that will need to be designed by an engineer so that the concrete slab will structurally bear the weight of the shop structure you build above it.
Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA's role is to ensure these conditions for America's working men and women by setting and enforcing standards, and providing training, education and assistance. For more information, visit www.osha.gov or call OSHA at 1-800-321-OSHA (6742), TTY 1-877-889-5627.
There are benefits to either approach. Sharing a common wall with your house can require some careful soundproofing but can reduce heat loss and exterior finishing costs like siding. A shop located in an addition is more likely to be allowed to have living space or storage space above it, and it may be easier to make use of the existing plumbing and electrical and heating systems of your home to service your shop space. Another advantage of an addition is not having to run to an outbuilding in minus-30-degree weather or a summer downpour.
Here’s a safe and sound way to make long cuts with a circular saw on plywood clamped to a worktable. Cut about 12 in. into the plywood, then twist a piece of duct tape into a bow tie, with up-and-down adhesive faces. Slide it in the saw kerf and press the tape down above and under the plywood. Now as you finish the cut, the trailing end can’t curl down dangerously as you saw. Hats off to Mike Connelly for simplifying this job. Check out how to make this DIY duct tape wallet.
Unless you’re a big fan of frequent shop remodeling, planning the layout of your workshop early in its development will save you a lot of time and trouble and also can keep you from spending years in an uncomfortable, poorly organized space. And if you already work in a shop that’s as organized as a trailer park after a tornado, careful planning and a little remodeling is likely to help you make a quantum leap.
