Engineered Stairs - Building And Construction
Engineered stairs would be any stairway that would require structural engineering. The engineer will provide the builder with material sizes, construction methods and detailed information.
For Example: There's a good chance that the stairway
in the picture above was not engineered or engineered correctly. I run
into problems like these often, because some engineers and architects
rely on experienced carpenters to solve simple problems.
I doubt if this stairway will ever fall down or have any problems, but
with a little more efforts, it could have been designed and constructed
correctly.
Engineers often provide construction workers with material sizes. One
engineer might request 2 x 14 construction standard lumber will be used
for the stair stringers and 3/4" plywood will be used for the stair
treads and risers.
Another engineer might require 2 x 12 construction standard for stair
stringers, treads and risers.
You will usually find all of the information you need to build a set of
stairs, within the building blueprints, provided by the architect and
engineer.
