M-601 M-602

Hot Water System: Pump schedule indicate pumps rated for 48 GPM. Total HW load for equipment listed is 48 GPM, which does not include the 17 convectors scheduled without a GPM listed. Please Advise.

"Size pumps for 58 gpm at 85 wc pressure drop.

On sheet M-601, PUMP SCHEDULE, change P-1 and P-2 GPM from ""48"" to ""58""."

191 M-602 FC-1-1 has a heating load, but no GPM listed.

Please Advise.

"The Flow Rate GPM for FC 1- 1 is 1.0.

On sheet M-602, FAN COIL

UNIT SCHEDULE, change FC 1-1 Flow Rate GPM from ""-"" to ""1.0""."

PIPING PLAN, where the HW piping goes up in the chase adjacent to Stair 001, change HW piping size from ""2"""" to

""2-1/2"""". "

194 M-602 Air separator does not list flange size, should we assume piping main size is the intent?

The flange size on the air separator will be based on the air separator manufacture's selection based on the capacity of the air separator. Typically it will be the piping main size.

195 MP102

MP-102 indicates the CHW and HW mains in office 208 are 2”, please confirm the HW main should be ¾” as indicated further down on the system. Please Advise.

"The HW main should be 1"" at the location shown as 2"".

It changes to 3/4"" after passing by the two fan coil units 2-6 and 2-7

On sheet MP102, SECOND

PIPING PLAN, where the

HW piping runs between the chase and FC-2-6, label pipe as 1"" and remove HW pipe label that states 2"". "

MP102

MP103

Drawing MP-102 indicates 2-1/2” HW up in chase to 3rd floor, drawing MP-103 indicates pipe size is 2”. Please Advise.

"2"" is correct.

On sheet MP102, SECOND

HW pipe between the chase adjacent to Stair 001 and

CUH-3 as 1-1/2"". "

198 MP103

Drawing MP-103 indicates 2” HW mains extending up to the 4th floor from the chase, but drawing MP-104 does not indicate piping extending up to the 4th floor in this location. Please Advise.

"Piping in the chase does not go up to the 4th floor.

PIPING PLAN, at the chase adjacent to Sair 001 Change

199 M-601

Chiller schedule on drawing M-601 indicates verifying buffer tank size with manufacturer. Is the size listed on the schedule based on a specific manufacturer, and if so, please advise. Otherwise we assume for purposes of the bid, we will figure 200 gallons as indicated.

The buffer tank size of 200 gallons is adequate for bidding, as labelled in the

AIR COOLED CHILLER

SCHEDULE on Sheet M- 601 that was updated in

Amendment 01.

MP103

MP104

Drawing MP-103 indicates 2” CHW mains extending up to the 4th floor from the chase, but drawing MP-104 does not indicate piping extending up to the 4th floor in this location. Please advise.

202 MP101

Drawing MP101, please provide detail for exterior CHW pipe supports.

A detail for exterior pipe supports was provided on a revised Sheet M-502 under

Amendment 04.

203 M-601 Steam PRV indicates 15 PSI outlet pressure, heat exchanger HX-1 indicates 10 PSI inlet pressure. Please advise.

15 PSI outlet pressure for PRV is correct. The steam control valves have a 5 PSI pressure drop so the heat exchanger will receive 10PSI steam.

204 M-502 Drawing M-502 detail C2 indicate steam 1/3 & 2/3 valves, but capacity and pressure drop are blank. Please advise.

"Values are as follows:

-2/3 Capacity Steam Valve:

523 LB/HR capacity and minimum 5 PSI pressure drop.

-1/3 Capacity Steam Valve:

260LB/HR capacity and minimum 5 PSI pressure drop.

On Sheet M502, MECHANICAL DETAILS

2, in Detail C2, update values for control valves to the following: ""2/3

CAPACITY STEAM

VALVE; 523 LB/HR, MIN 5

PSI PD. 1/3 CAPACITY

STEAM VALVE; 260

LB/HR, MIN 5 PSI PD."""

205 M-502 Detail indicates 4” steam piping, drawing MP-101 indicates 2-1/2”. Please advise.

"2-1/2"" is correct.

On drawing M502, 2, in Detail C2, change the steam piping from ""4"""" to ""2-1/2""""."

206 M-502 Detail indicates 2-1/2” condensate from the heat exchanger, please confirm this is correct.

"2"" is correct.

2, in Detail C2, change the LPC piping from ""2-1/2"" to ""2""""."

207 M-502

Detail indicates a steam trap sized for 1524 lbs/hr, which depending on design pressure drop, trap size would be either 1”, 1-1/4”, or

1-1/2”. Please Advise.

"The steam trap should be sized for 785 lbs/hr.

Coordinate trap size with manufacturer's recommended size for this capacity.

2, in Detail C2, in the note in adjacent to the left support leg, change ""1524"" to ""785""."

208 MP101

Drawing MP-101 indicates HPS steam in locker room 103, but in mech room detail same drawing, indicates LPS. Please advise.

"LPS is correct.

On sheet MP101, FIRST

PIPING PLAN, change pipe labels near Locker Room from ""HPS"" to ""LPS"". "

209 MP101

"Can a detail be provided for the steam entrance into Mech room 101, assuming the steam PRV will be located there along with steam meter.

- Will there be a flash tank required.

- Is the intent to tie in the HPC into the pump condensate piping, or should it be piped to the condensate receiver? Please advise."

"A flash tank will be required for the HPS trap.

Vent the flash tank to exterior steam vent. Pipe

HPC to flash tank. Pipe flash tank condensate to pumped condensate piping. See Detail A5 on attached revised Sheet M-503.

SCHEMATIC.

Note that this response affects the response to PPI #151 issued under

Amendment 04. In the response to PPI #151, change the first sentence to read ""Per the response to PPI

#209, issued under Amendment 05, a detail has been provided in for the steam pressure reducing valve assembly. See the response to PPI #210, issued under Amendment 05, for steam meter assembly information"", and in the second sentence, change

""C2/M-502"" to ""A5/M- 503."""

MP101

M-503

Drawing MP101, keynote 3 references drawing M503 detail C2. This detail is not included, please provide detail.

A steam pressure reducing valve assembly detail is provided in the response to PPI #209. A steam meter detail will be provided after contract awarded. For bidding, provide a 2-1/2" vortex steam meter with a 2- 1/2" bypass with normally closed shutoff. Include two shutoff valves to isolate the steam meter as well as a strainer. Provide MODBUS

IP communications translator with two outputs, one for AMI and another DDC system monitoring.

211 M-503

Please confirm detail C2 on drawing M-503 meets requirements of ATFP. Only way to quantify this bid item is to provide engineering prior to bid which is not feasible. Please advise.

It is important that a well qualified party is involved during the bidding stage of this delegated design to use their experience, and based on the equipment information provided in the project documents, to quantify the ATFP equipment supports.
