Option 3

Delegated Connection

Design Work


44/65

MARKETING


The complete connection design shall be

shown in the structural design drawings

Option 1


45/65

MARKETING


The complete connection design shall be

shown in the structural design drawings

The SER designs the connections

Option 1


46/65

MARKETING


The intent of this approach is that complete

design information necessary for detailing theconnection is shown in the structural design

drawings. The steel detailer will then be able

to transfer this information to the shop and

erection drawings

Option 1


47/65

MARKETING


The connection shall be designated to be

selected or completed by an experiencedsteel detailer

Option 2


48/65

MARKETING



selected or completed by an experiencedsteel detailer

The SER provides the schematics and the

steel detailer completes the details

Option 2

It is not the intent that this method be used

when the practice of engineering is required

Any restrictions on types of connections

The connection design loads and associatedcriteria must be defined. Forces, moments,

whether the loads provided are ASD or LRFD

loads, and similar information is key here

What substantiating connection information,if any, is required



57/65


58/65

MARKETING


The connection design engineer must review

and confirm in writing, as part of thesubstantiating connection information, that the

shop and erection drawings properly

incorporate the connection designs.

This review does not replace the approvalprocess of the shop and erection drawings by

the SER. It is in addition to it.

The SER is identified as the final authority in

the case of a dispute between the SER andthe licensed professional engineer in

responsible charge of the connection design

when option (3) is specified. This is simple

and straightforward, and it is how it must bebecause only the SER has the full knowledge

of the structure.

Final Authority

Simple and straightforward approach to a

practice that already exists, is in wide use,and currently is widely varying in how it is

used.

Has appropriate limits for all three options.

Language allows all parties to control theirown risks, and no party is asked to assume

the responsibility for the negligence of

another party.
