36C24626B0001 Replace MRI 1.5T Amendment 0001 Responses to Vendor Questions Could you please confirm whether the new 1.5T MRI system has already been procured by the VA, or if the Department intends to issue a separate solicitation for the equipment? The new MRI Machine has not been procured by the VA at this point. Radiology/Bio-Medical plans to submit the package to NAC by December 31,2025. We would also like confirmation if the site visit listed for today was deemed mandatory for a compliant bid. No Is the floor recessed? No, per As-Built drawings, there is a built-up floor above the existing RF Shielding that will need to be removed. See Sheet A101 in forthcoming Addendum 01. May we avoid the pillar on the south wall by making the shield go straight across without having to go around the pillar? A straight, uninterrupted wall with no bump-out is acceptable, with the following requirements, however, the design intent of wrapping the column does not change with the RFI response: ABA clearances around the doors are to be maintained. The 1 RF Wall Panel and 4 1/8 Gypsum on Wood Stud wall are to remain continuous throughout the entire length of the wall. No interruptions. May we have a .dwg file? The awarded contractor will have access to all the CAD files that they need. What type of magnet hatch for delivery: side or ceiling and its location? If referring to the removal and installation of the old and new machine, then it is a side delivery. This is located on the west side of the building with the loading dock. Do we know that Siemens has confirmed that there will be no active interference between the two MRI systems? We have the ability to quote magnetic compensation but need to know if it's necessary. Response forthcoming in additional amendment. Solicitation Bid submission: Will the Government authorize electronic bid submissions? Please refer to the Instructions to Offerors page on bid submission. Lay-down and dumpsters: where will the lay-down and dumpsters area be located? Ideally, the best area for a lay-down and dumpster location is on the West-side (loading docks) of the MRI Machine. Currently, HICAPS has control of this area and we hope their project will be finished by the time this one proceeds. If this does not work, we can look for an area under the walkway. Space is very limited on campus so can address this as we move forward with the project. SSHO: spec. 01 35 26/1.9/C calls for the SSHO to be a separate individual from the superintendent and QC (which can be held by 1 individual). Because of the small size and limited complexity of the project would the government accept 1 person to cover all 3 roles?

7. Do we know that Siemens has confirmed that there will be no active interference between the two MRI systems? We have the ability to quote magnetic compensation but need to know if it's necessary. The contractor will not be responsible for any magnetic compensation 25. PACS: Can we the government please provide existing control panels and headend software id info, licensing info and photos? The PACS is primarily controlled by a Phillips Filter Box in the Mechanical room behind the MRI machine. The Filter Box works in conjunction with a control panel located in the control room at the front of the MRI machine (see pictures below). Once the Radiology enters pertinent information on the images, they are sent to a Mckesson System. Durham VA uses Change Healthcare Radiology Solutions 14.1, conforming to Digital Imaging in Communications In Medicine (DICOM) 3.0, as the stand for handling, storing, printing, and transmitting information in medical images. 26. Finishes: Drawing A102 finish legend: All colors are listed as TBD. Can the Government please provide colors for all finishes? Blue and Green accent colors.

It calls out fiber for the injector to the actual MRI machine. Need to know if it is Sigle Mode or Multi Mode fiber. How many strands of fiber they are needing there and the type of connectors they need on the end of the fiber. Injector has a fiber optic cable that is supplied with the purchase of the injector, so the contractor is not responsible for providing that cable. There is no additional fiber needed for the MRI machine. Need to know how many data drops per location it is not called out anywhere also need to know how many data cables are being demoed. 4 drops per location and there are none that need to be demolished. Any other fiber on this job would need to know the same questions on that fiber as the fiber mentioned in question 1. There is no additional fiber needed for the MRI machine. Per point 2. of the Addendum_1_Narrative regarding Revised Door Hardware for RF Shielding Room, Specification 08 34 46, those specs do not actually pertain to RF shielding for MRI rooms. They look more like specs for acoustic rooms. Please see attached updated specifications.

Will three radial hinges and a low-profile brass threshold for doors be acceptable? The brass threshold is acceptable. Regarding the hinges, the design intent for the continuous hinge is a) greater durability, and b) to help insure a greater RF seal. All doors during Shop Drawing reviews will be reviewed against this standard."
