PART 3 EXECUTION
3.1 Examination
3.2 Erection
A. Allow for erection loads, and for sufficient temporary bracing to maintain structure
safe, plumb, and in true alignment until completion of erection and installation of
permanent bracing.
E. After erection, prime welds, abrasions, and surfaces not shop primed, except
surfaces to be in contact with concrete.
F. Grout under base plates. Trowel grouted surface smooth, splay neatly to 45
degrees.
A. Visual Inspection:
1. As a minimum carry out visual inspection of all shop and field welds in
accordance with AISC or BS standard.
