2. In review of the seismic coefficients, it appears that the values for a chiller were used, but vibration isolators are intended for the base. Should the coefficients for vibration isolated components be used in lieu of those for a hard tied chiller?

3. Please verify the adequacy of the existing roof to support the new chiller. This can be completed by verifying the weight of the new unit is less than 10% greater than the original or by verifying the capacity of the roof will not be exceeded.

4. For the CGA 130 ton unit, are the two additional mounting holes for "wind load option" required as shown on Figure 16 of the installation guide (CG-SVX17M-EN)?

5. The net overturning force appears to use the uplift equation without overstrength, but the shear value includes overstrength. The Hilti calculation is listing that the overstrength is considered in this calculation. Overstrength should be applied to both equations' horizontal component of seismic loading. Please review and update as applicable.

6. What is the depth of concrete the anchors will be installed in? Please include this value or a minimum requirement on the structural drawing.
