CONSTRUCTION OF OUTDOOR LIVING COMPONENTS WITH THE TANDEM MODULAR GRID
CONSTRUCTION LUMBER
Building the different units in this guide requires construction lumber
for the framing: 2 × 4, 2 × 6 and 2 × 8 boards, 4 × 4 and 6 × 6 posts
and plywood sheets . We recommend that all wood used outdoors be
treated against rot according to established procedures approved by Health
Canada . You should use S-P-F #1 or #2 wood, or better . This type of wood
usually has a minimum life of 15 years without maintenance in normal
outdoor conditions .
Note : Wooden components that have been cut or sawed
should be treated with an anti-rot product .
COMPLIANCE WITH CONSTRUCTION STANDARDS
In all circumstances, units to be constructed must always comply
with the requirements of the National Building Code (version specific
to your region) and local municipal bylaws and regulations .
