Erection Issue Eliminated Through Suggested Changes in the Splice Connection During Detail Engineering

Issue Identified During Detail Engineering

• During detail engineering, it was identified that the design specifies both-side web plates, with shop weld on one side and field bolts on the other.
• This would have created a field erection issue, as the shop-welded web plate on both sides prevents secondary beam placement.

Proposed Solution: Fully Bolted Connection

• Use bolted connections on both sides instead of welding one side.
• This allows the web plate to be shipped loose, making field installation easier.
• At the site, the secondary beam can be placed first, followed by the web plate installation and bolting.
• Factory-drilled holes ensure precise alignment and better quality.
• Eliminates on-site welding hazards and inspection issues.

Client Approval

• The client accepted the suggestion due to its practical benefits and ease of installation.
• The change improves efficiency, cost-effectiveness, and safety.

Conclusion

• Switching from welded-bolted to fully bolted improves constructability.
• Ensures stronger, safer, and more efficient structural connections.
• Small design changes can greatly impact project success.
