1. The sizes and locations of anchors havr : een determined.

Yes*

2. Appropnate equipment charactenstics have been determined (mass, CG, natural freq.,

Yes damping, center of rotation).

3. The type of anchorage is covered by the GIP.

Yes

4. The adequacy of the anchorage installation has been evaluated (weld quality and length, nuts Yes and washers, expansion anchor tightness, etc.)
5. Factors affecting anchorage capacity or margin of safuty have been considered: embedment Yes length, anchor spacing, free-edge distPACe, Concrete strength / condition, and concrete cracking.
6. For bolted anchorages, any gaps under the base are less than 1/4.

Yes

7. Factors affecting essential relays have been considered: gaps under the base, capacity Yes reduction for expansion anchors.
8. The base has adequate stiffness and the effect of prying action on anchors has been Yes considered.
9. The strength of the equipment base and the load path to the CG is adequate.
