how do we propose code changes?
many times, we talk amongst ourselves about a particular code issue but how often does our concerns ever get expressed to the proper committees that are responsible for the codes? i believe there is a real need to open up this line of communication.
if we have a specific suggestion or problem about a particular code issue, what procedure can we use or who do we need to contact to propose a change or express our opinion?
i know that there is, generally, a review period during which most code committees solict comments before finalizing the code. however, it is not until a particular jurisdiction adopts that code and the architects and engineers start using it, that we really dig into the details of it. then the code complexities, inconsistencies and omissions become more apparent.
it would be great if we could put together a list of contacts for particular codes.
some codes that come to mind:
ibc 2000
asce 7
aci 318
aci 530
aisc
nds
wouldn't it be great if we could automate this procedure and send on series of relevent posts to a particular committee or committee member by checking a box?

i agree that it would be more useful to send info. on a code problem, its impact and a recommended solution.
for many of us, our employers will not pick up travel expenses or meeting time and so this prevents our involvement.
we certainly can and are willing to send off an email, but we need to know who and where to send it. where can we get this info.?
the review periods for these codes are not always made known to the professional community. how can the notification of these review periods be more widely distributed to the professional community?
