If you are going to re-use the original drawings, you need to be satisfied
that they are correct and complete. You probably need to check the lateral,
as the forces increased slightly for 1997, and some of the requirements
changed. (Redundancy, near-field source factors....)
The change in roof framing may change the load path. If you are changing
from a trussed roof to a stick framed roof, some of the interior walls may
carry roof load, where they weren't carrying roof load before.
Just a few thoughts to get you started.

Subject: pre-engineered plan
I have a client brought me a job already engineered (plans and calculation
and details ) by anther engineer under 1994 ubc code
he asked me to do the calculation again using the same plans
and the details using 97 ubc
I want to know if I can use the same plan because I do not think
I can change any of the beams and the layout of the floor joists
the only thing that he wants to change roof trusses to roof joists
the foundation is post tension which is existing
the other thing I can change the details
I like to other engineers opinion
Thanks in advance
