Refer to contract specifica�ons for requirements. See spec sec�on 013526 Safety Requirements.

3 The project SOW indicates that the “GC is responsible for acquiring a contract with Siemens Healthcare & Eaton Corp to provide the necessary site-specific design, …”. Has Monument acquired this?

Refer to contract SOW for requirements. The general contractor is responsible.

4 Do you have specifica�ons on the new power condi�oner and UPS?

Siemens specified that the following Eaton UPS is approved for the Siemens Magnetom Sola Fit MRI at VA Brockton, for complete system backup without interrup�on. Atached is the Eaton 93PM UPS brochure with specifica�ons.

5.1 minutes.)

Network Card Eaton 24x7 start-up One year (24x7) warranty through Eaton Corp.

Shipping to the customer’s dock Op�onal Remote Monitoring Panel

5 Do you have specs on the exis�ng power condi�oner?

Please see atached (2) PDFs. "Eaton 93PM 180kW 3-Wire Maintenance Bypass Sidecar Installa�on Informa�on (7-21-16) (Red-Lined)" and "Eaton 93PM 180kW 3-Wire UPS Installa�on Informa�on (7-29-16) (Red Lined)"

6 Is the exis�ng power condi�oner curre4ntly func�oning properly?

It is reported to be func�oning properly.

7 Who is responsible for disposal of the exis�ng power condi�oner?

Refer to contract SOW for requirements. The general contractor is responsible.

8 All the drawings received by US & have a date of 2021 or earlier. Do you have drawings dated 2024 for this project?

The drawings were completed in 2021. The project was funded in 2024.

9 Do you have drawings which show the loca�ons of the exis�ng electrical panels from which branch circuits required on this project will originate?

Refer to contract drawings.

10 Will your fuel tank subcontractor furnish, install and test the fuel system complete, including the alarm and monitoring?

Refer to contract SOW for requirements. The general contractor is responsible.

11 Is there a wiring diagram which depicts what power and communica�ons cabling is required for the fuel system?

Refer to contract drawings.

12 What is the piping distance from the tank to the pump set and from the pump set to the generator?

Refer to drawing CSK-02 within package for approx. dimensions. Drawings require to verify in the field.

13 Are you looking for all fiberglass piping, including the vent pipe?

See drawings and specifica�ons for requirements.

14 Typically we install 2" vent pipes, is there a specific reason you are looking for a 4" vent pipe?

Refer to drawings and specifica�ons for requirements, including underground fuel oil tank schedule.

15 What is your intended plan for a transi�on sump? Refer to drawings and specifica�ons for requirements.

16 What is the exact loca�on of the pump set on page 1 of the drawings?

See full set of drawings.

17 What type of monitoring system are you looking for?

See drawings, specifica�ons and RFI responses for requirements.

18 Drawing H4.00 notes for the exis�ng 300kW/375kVa generator to be connected to the building DDC system for “all monitoring points” and states to provide at a minimum low fuel level, low fuel alarm, high fuel level and high fuel alarm. In review of the Engine Generator Resubmital provided, there does not appear to be sufficient specific informa�on on how Siemens could accomplish connec�ng monitoring points. It appears the generator has a controller, remote serial annunciator, and day tank controller. The generator controller appears to have op�ons for connec�ng to a computer or Modbus but does not detail if included or how they could be used for monitoring. It also lists outputs including 31 user-defined relay driver outputs which may require dry contact connec�on to a Siemens controller, but the quan�ty required is not defined in the SOW or if this is the direc�on for Siemens to connect with. An op�on appears to be included for a common failure relay that may also be used.

Siemens requests VA provide clear direc�on on what points must be �ed in and how they are to be �ed in.

Refer to the provided MRI Engine Generator Approved Submital. The generator has a controller and a remote annunciator panel that is located in the building 3 Operators Suite A136A. The exis�ng panel has all the points that are needed, so the contractor just needs to integrate the new work into the exis�ng controller and remote annunciator panel. The drawings and specifica�ons require coordina�on with the generator manufacturer.

19 Drawing H4.01 for the Diesel Fuel Maintenance System has notes 1 to provide a control panel with BMS integra�on and note 3 to coordinate control requirement with control contractor. The controls contractor is Siemens. In atemp�ng to provide a panel with BMS integra�on for the basis of design system and to coordinate the bid for the Siemens controls, we have found that the controller for the fuel system is not capable of having a BACnet (or other supported language) integra�on which is what Siemens would require to integrate to. The fuel oil system has local type controls with local alarms similar to those on H4.02 but cannot “integrate” to the Siemens BMS. A�er checking with mul�ple specialty vendors, we cannot locate any fuel system control panel that is available that has integra�on as men�oned in the design documents and we request a clarifica�on on the basis of design control panel manufacturer be provided or other direc�on on how to have the system integrate to the Siemens BMS.

Disregard connec�ng to Siemens BMS. Refer to the provided MRI Engine Generator Approved Submital. The generator has a controller and a remote annunciator panel that is located in the building 3 Operators Suite A136A. The exis�ng panel has all the points that are needed, so the contractor just needs to integrate the new work into the exis�ng controller and remote annunciator panel.

The drawings and specifica�ons require coordina�on with the generator manufacturer.

20 Sec�on 256000 appears to be a specifica�on for sequence of opera�ons for temperature controls per 1.2.A. The descrip�ons in the sequence for generators, transfer switches, and fuel systems appear to require the ATC Contractor (Siemens) to install the controls devices and refers to the diagrams on the drawings. Specific informa�on is not shown for the generator or ATS controls and this specifica�on is not specific to how these are to be controlled by Siemens and clarifica�on is required.

It is not clear if this specifica�on matches the drawing layout.

21 H4.02 drawing show DDC controls points for the fuel oil pumps (start/stop, status and alarm per pump). Are these hardwired points or integra�on?

H4.01 drawing details calls out valve package and controls. Please confirm

22 How is Siemens to connect to the network? Where is the closest network switch for a controller to connect to? How is Siemens to get the communica�on out to the fuel system and generator loca�on? Will there be an underground fiber network and conduit run and who is responsible to get the network connec�on to the area?

Disregard connec�ng to Siemens BMS.
