On drawing M-503, detail A3 depicts 2 of the 2" CWS and 2of the 2" CWR lines per unit. However, the floor plan drawing MP-101 only indicates 1 of 2" CWS and 1of 2" CWR line per unit. Please clarify.

The detail is incorrect. Only (1) 2" CHWS and (1) 2" CHWR are required per the floor plan.

There is no detail indicated on the drawings for the Heating Water coils at the air handling units. There is a detail for the Chilled Water Coil shown on drawing M - 501. Are we to use the same detail for the Heating Water?

Yes, the chilled water coil piping detail can also be applied to the hot water coil at the air handling units.

Drawing S404 & S405 is depicting rebar on CMU walls called out with a reference "See wall Schedule on S-601 for Reinforcement", however drawing S-601 shows no schedule or details for masonry walls, please provide additional details for CMU wall reinforcement.

I think the question is, why aren't they mentioned? Also, is there any additional information available about these pipes?

"Insulation specification 23 07 00 sections 2.3.1 cold pipe line and 2.3.2 hot pipe line. These two systems are not listed on the table 1 and table 2 under section 3.2.1.6 pipe insulation material and thickness."

Drawing E-401 & E605 Shows PHWP-1A & PHWP-2A starters, but the equipment that it is serving are not shown.

Where are the water pumps that they are feeding?

PHWP-1A is in the same location as PHWP-1B but they stack vertically so it doesn't show up on the floor plan. They both serve boiler B-1 with one of the pumps serving as a backup pump on stand-by. It is the same for PHWP-2A & PHWP-2B except that they serve boiler B-2
