Delegated connection design can be a beneficial way for the EOR to provide a superior product, but only if done correctly.  Delegating connections allows the fabricator to use preferred, and often more economical connections, however good communication is necessary to prevent inaccurate bidding, change orders, and delays due to RFIs.

In the May 2025 SEU Session, Kyle Jenkins, PE, from Advantage Structural Engineers, presented Tips for the EOR when Delegating Steel Connection Design.  Kyle explained ways to produce better drawings that provide the information needed for safe and efficient delegated connection design.  He described the importance of communication in the delegated design process and gave examples of negative outcomes that can come from poor communication.  Kyle identified some best practices for setting up and delegating types of shear, moment, and bracing connections.

Kyle noted the importance of providing realistic reactions on design drawings.  Accurate reactions lead to more efficient structural designs and decrease costs for the owner.  Providing reactions also promotes better quality control for the EOR when reviewing the shop drawing details.  To hear Kyle explain this best practice, watch this short video:

Kyle also noted the EOR should specify whether reactions are ASD or LRFD and avoid using terms like “Factored” or “Service” since these terms are no longer relevant as wind and snow loads now are factored to ASD levels.  Specifying reactions to be ASD or LRFD eliminates confusion and clear communication prevents negative outcomes.

The burden to provide an efficient and safe design is shared by the EOR and the delegated design professional.  Establishing good communication and providing accurate reactions at connections will benefit the team throughout the design and construction administration process.
