calcs for performance spec components
our firm often requires submittal of structural calculations for building components such as wood trusses, precast plank, etc. the calculations are specified to be prepared by a licensed structural engineer in the project's state.
what we get back varies widely. for example, we have had 20-page calculations on stone facing material and a 1-page summary sheets for wood trusses.
my question is three-fold:
1. how good (detailed) are the calculations you receive for preformance spec. items?
2. have you tried to specify the level of detail you require?
3. if you have specified what you want for calculations, how did you do it and how well did it work?
thanks,
joe
joe,
i have seen the same as you describe. it varies from little to too much, but the structural engineer of record maintains the responsibility for compliance with the design and intent, so can dictate how much or how little he wants to see. i don't know of any particular standardization; however, the state of florida includes specific language in its rules of practice on delegated structural engineering functions (
