Specifications, and as indicated on final shop drawings.
B. Properly mark and match-mark materials for field assembly. Fabricate for delivery sequence
which will expedite erection and minimize field handling of materials.
C. Where finishing is required, complete assembly, including welding of units, before start of
finishing operations. Provide finish surfaces of members exposed in final structure free of
markings, burrs, and other defects.
D. Connections:
1. Shop Connections: Weld or bolt, as indicated.
2. Field Connections: Bolt, except where welding is indicated.
3. Where steel-to-steel beam connections are not detailed in the Drawings, provide

load capacity of the given shape for the span and for the steel specified.
E. Fasteners: Provide high-strength threaded fasteners for principal bolted connections, except
where unfinished bolts are indicated.
F. Minimum Welds: All intersecting steel shapes which are not bolted shall be connected by a
fillet weld all around. Fillet weld sizes that are not shown shall be 1/16" less than the thinnest
of the connected parts for thicknesses 1/4" and larger. Fillet welds on plates less than 1/4"
shall be of the same size as the thinnest of the connected part.
G. Holes for Other Work: Provide holes required for securing other work to structural steel
framing, and for passage of other work through steel framing members, as shown on final
shop drawings.
