Please verify that the statement within the double lines and bolded block on many Electrical drawings is correct (ie: NOT ALL KEY NOTES USED ON THIS

SHEET). All drawings containing this Note have several demolition and/or new work notes described but that are not shown on the demolition or new work plans. We understand the statement within the block to mean that if any particular note is not located on the demolition and/or new work plans on any given drawing that the work in NOT require don that particular drawing. Please confirm.

Please clarify that the new work notes describing the low voltage power wiring to each flush valve is also a requirement for low voltage power wiring to each automatic faucet (this work is depicted but now described in the new work notes).

The drawings require a single low voltage control transformer to be installed and used to power the lavatory faucets and flush valves for the toilets and urinals. All low voltage wiring shall be installed between the transformer and the fixtures served. This condition is required for all public toilet room work on the 1st, 2nd, 3rd, 5th, and 10th floor.
