Most of these are technical in nature, while the last one relates to the owner's consent to using the specific type of system indicated on the design plan (this is the document which is apparently being prepared and signed and provided to Toni. Since we are completing this plan review today and it is currently not in your possession it remains in this letter). Any questions, do let me know. Thanks.
