Re: Connection Responsibility

[Subject Prev][Subject Next][Thread Prev][Thread Next]


Per the SEAOC commentary to the UBC, connection design for seismic loads by the
fabricator is FORBIDDEN.

UBC 1633.2.3 Connections.  Connections that resist design seismic forces shall
be designed and detailed on the drawings.

SEAOC (Blue Book) C108.2.3  Connections.  In some geographical regions,
particularly those with low seismicity a practice has evolved that leaves the
design and detailing of connections to the fabricator or constructor
(notwithstanding its criticism by the American Society of Civil Engineers).
This practice is absolutely prohibited by this provision........

Subject:  Connection Responsibility

I know that the subject of who is responsible for connections designed by the
fabricator or detailer has been hashed over and over, however over the past year
I have started to see a large rise in jobs being bid that place the liability on
the fabricator or the detailer. Now these jobs are not in the East where it is
common for the fabricator to do this work (but not take the liability), but
these jobs are showing up in the West in zone 3 and 4 areas.

The question of the day is this legal or are the engineers making these
specifications and exclusions just sticking their heads in the sand and thinking
that they have protected themselves by use of a few weasel words? And just think
what a bunch of lawyers would do if they found some engineers with their heads
in the sand and their butts in the air.

The reason for this question is not to start the debate over again but to get
some hard information show  these engineers that they may not be protected by
the exclusions in their drawing and specifications.
