By Engineer or By Supplier? How “involved” to be in choosing engineered lumber

Since Engineered Lumber Products are proprietary, there is a range of opinions about how much information to show on a set of Structural drawings. Should the framing choices be left to a supplier (similar to roof trusses), or should specific sizes and grades be specified?

This decision affects the time-sensitive process of putting together an estimate and can affect the quality of the construction itself. Through our experience working on over 100 mid-rise projects, we provide 5 examples where information provided on the Structural Plans can make a big difference.
