(1) General requirements for erection stability.

(a) All columns must be anchored by a minimum of four anchor rods (anchor bolts).
(b) Each column anchor rod (anchor bolt) assembly, including the column-to-base plate weld and the column foundation, must be designed to resist a minimum eccentric gravity load of three hundred pounds (136.2 kg) located eighteen inches (.46 m) from the extreme outer face of the column in each direction at the top of the column shaft.
(c) Columns must be set on level finished floors, pregrouted leveling plates, leveling nuts, or shim packs which are adequate to transfer the construction loads.
(d) All columns must be evaluated by a competent person to determine whether guying or bracing is needed; if guying or bracing is needed, it must be installed.
(2) Repair, replacement or field modification of anchor rods (anchor bolts).

(a) Anchor rods (anchor bolts) must not be repaired, replaced or field-modified without the approval of the project structural engineer of record.
