Design of masonry window sill
(OP)
Is the masonry below a window to be desinged as a cantilever? I notice that drawings from another consultant does not show this as reinforced. Could this be a mistake?
The situation I'm referring too is 3 feet of 8" block below a 12'-0" wide x 5'-0" high window.
If designed as a cantilever the block needs reinforcement. I don't think windows should be relied on to provide lateral support.
Can anyone comment on this?
Thanks.

Will have a bond beam with reinforcing under the window anyway. If normal BB reinf is not sufficient, increase it or the BB depth to make it work.
Chances are that minimum reinforcing will work unless you are in a high wind area.

As msquared48 mentioned, there should be a bond beam right below the window which spans horizontally to the jambs.
