Continuous or periodic Special Inspection of A706 rebar to connection angles

[Prestressed Guy]

I am working on a SDS D precast project and may have a tension connection that will require field welding #6 or #10 bars to ship-loose angles to develop tension across a joint. Originally I planned to have the rebar shop welded to plates in a D1.4 certified shop and 5/16" fillets to make the field connections. This would fall in the 5/16" max single-pass periodic welding requirement. It seams to me that I would probably require continuous inspection of the flair-bevel welds to the connection angles.
Anyone have any thoughts?

Bump.
I didn't get any responses to this post. What is the thoughts on Continuous inspection of welds? My understanding is that the continuous requirement is not that the inspector is standing over the welders shoulder with hood down 100% of the time that all welding is done. It does require that the inspector be onsite and checking progress on a regular basis.

IBC Chapter 17 requires periodic inspection for single pass fillet welds of rebar, 5/16” or smaller. Everything else needs to be continuous.

Continuous to me means inspector watching them do the work. Maybe not ‘hood down’ as you’ve noted, but should be right where work is being done at all times while the subject welds are being made, not wandering around site doing other things. For multipass welds, for example, inspector needs to be hanging around so they can inspect every pass before it gets covered up by the next one. Don’t necessarily have to be intently watching every inch of weld go down, but can’t really be doing something elsewhere on site either.

Chapter 2 defines it as “Special inspection by the special inspector who is present continuously when and where the work to be inspected is being performed.”
