hib-91 or bcsi
i would like to know whether i should specify hib-91 or bcsi 1-03 for a guideline to truss handling and bracing.  does it really matter which one to use? is one stricter than the other?  thanks in advance.

bcsi 1-03 replaces hib-91 and is a booklet that is composed of lots of addtional information relevant to truss erection, handling, and bracing.  specifically, bcsi-b1 presents the equivalent information as hib-91.
