As send per e-mail of 13/6/2016. Before revising the P&IDs that has been reviewed please clarify on the following points. 
This would save the time on further revisions.

Utility PID: TFS-15-47-PID-20 sh1of5_rev01 - Utility Model-JST20160608

1.	Comment TFSBV: All taps in hall are foreseen with warm water connection, this has to be supplied by TFS. Additionally the taps for the utility stations have to be foreseen with warm water. So please provide continuous warm water supply system (for example a heat exchanger for heating PWS with steam for the warm water supply).

TFS-India: Can you explain for which applications hot water requirement is foreseen? And that too continuous supply?

Answer TFSBV: Hot water is required for all cleaning purposes (equipment, setups, high pressure cleaner, floor, parts in ultrasonic bath, etc.) on a daily basis, hence continuous supply is required.  Further also washing hands.
Hot water on tap is standard in NL.
If TFS India checks costs of continuous warm water supply system, we can check in NL for an alternative (electrical boiler)

2.	Comment TFSBV: P&ID is build up as per layout. Depending on location of vacuum systems, it means that vacuum systems should be on sheet 3 (left hand side) and header goes from sheet 3 to 2 (to 1?) to 4 and finally to sheet 5.

TFS-India: As headers connections to & from each sheets are properly shown then is this really required to shift the vacuum set up on the sheet no 3.

Answer TFSBV: Not necessary but sequences of branch connections should be correct.

3.	Comment TFSBV: Line codes missing of:
- branches
- condensate lines from setups
- condensate line to drain
  Please add line codes

TFS-India: For every utility lines that has been connected to the headers a unique TIE IN No has been given. This TIE IN points specifies the connections of each line on the set up to the header then what value addition will be achieved from adding lines codes of the branches, condensate lines so that they should be incorporated.

Answer TFSBV: To be added in final version of P&ID. This is for better readability.

LLE PID: remarks-TFS-15-47-PID-04_R4

1.	Comment TFSBV: Please draw DPT402 and DPT401 correctly. Thus including valves, drain, vent. Why not use same connection points as RLT measurements?

TFS-India: Please explain why two options of level transmitters are suggested? At Pilot Plant Nashik- only DPT is used and has been working efficiently.
DPT402 & DPT401 have a separate hook up diagram which will be supplied with next revision. To use same connections is a good option. During trials interface will be at only one location either at top side or bottom side so why not to use only one level transmitter that can be used interchangeably.

Answer TFSBV: The two options for level measurement is not our suggestion, for us only DPT measurement only is sufficient. Interchangeable measurement for DPT is OK, as long as mounting distances/sizes/etc of the measurement assembly  are identical for top and bottom (the assembly can be moved as 1 piece by disconnecting and connecting only 2 flanges, see hand sketch). Further on ATEX connectors to be used  for cabling.
