> supporting work, adjust and align in accurate locations and spacing
> before permanently fastening.
>
> B. [Bridging]{.underline}. Install bridging simultaneously with joist
> erection, before construction loads are applied. Anchor ends of
> bridging lines at top and bottom chords where terminating at walls or
> beams.
>
> C. [Field weld joists]{.underline} to supporting steel framework as
> indicated on drawings and in accordance with SJI \"Specifications\"
> for type of joists used. Coordinate welding sequence and procedure
> with placing of joists.
>
> D. [Touch-Up Painting]{.underline}. Cleaning and touch-up painting of
> field welds, abraded areas, and rust spots of shop painting is
> included in Section 09900, which is hereby included in the contract
