PROJECT NAME: EHRM Infrastructure Construction – Memphis, TN

TECHNICAL QUESTIONS AND VA RESPONSE TRACKING SHEET

ITEM

NO.

The cable counts appear to identify Data and Voice ports, however, in some instances where the cable numbers for Data and Voice are both 0 but the Ports/“P” identifier identifies a quantity. Are the correct cables per outlet related to the Ports/”P” identifier? Drawing snapshot below

RLF – The wrong tag was used on the New Area Sheets. The tag should have read “2D or “4D”. The “P” count indicates how many CAT 6A data ports need to be installed. The Cabling Notes on sheets TN-40x also indicate the total number of data ports for each TR. This number should correlate with the “P” port count. These counts can be used for the bidding process. The New Area sheets will be updated and provided as a Revision to correct the port detail. A General Note will be added that all voice ports are to remain in faceplates as is. The New Area sheets will show 2D 1V in some cases to indicate where voice drops are located.

There is a Cerner Note on Drawing TN000 that states the below, however, this note does not appear on the new installation drawings. Can you please confirm the requirements for providing allowance cables? Also, can you please confirm the allowance drops will be identified prior to cable installation and cutover?

RLF – The design team is not aware of where the CERNER drops will be located. We also do not know what equipment is anticipated at these drop locations. I was told by the VA to allocate 10 drops for CERNER equipment to be placed. The VA COR will have to provide this information. In many cases, the equipment may be able to be placed utilizing existing drops. The COR will need to compare the CERNER information with the drop utilization counts from the Demo Area sheets to verify need for additional connectivity.

VA – Provide allowance for 10 additional 2-port CAT 6A drops. Allow 150 FT for each run. Coordinate with COR on locations.

Is there an RCDD requirement for project management/oversight in Division 27?

RLF – No.

The sheet notes in the drawing states:

"Contractor to coordinate with the existing access control vendor to install a new panel in the new TR. The card reader and keypad for the new TR are to be fed from the new access panel. Existing card readers and keypads will be moved to the new control panel under a different project."

Can the existing Access Control vendor provide the panel capacity of new panels to accommodate existing readers? example: 4 door, 8 door or 16 door panels?

RLF – Although moving existing card readers from existing panels to new panels is not in scope of the EHRM project, it makes sense that coordination should be done to have the Aceess Control vendor place a new panel in the new TR that would have capacity to move exiting readers for that zone at a later time. I would expect the panel to have capacity, but not filled with controllers under this project.

VA – Provide 16-door panel.

VA – Contractor Quality Control (CQC) System Manager is assigned as CQC System Manager but has duties as project superintendent in addition to quality control (01 45 00 Quality Control, 3.4, B.). See response to Item No. 7 below.

Please clarify how the contractor can quantify and price the following statement from sheet TN100 “existing ceilings throughout corridors and rooms with existing cabling may need to be removed and replaced to accommodate construction. contractor is responsible for identification of scope of work associated with this removal and installation within base bid”.

RLF - I am not familiar with sheet TN100. Our Comment and Symbol sheet is TN000. This statement is also not familiar to me. I am not aware of any ceiling that would need to be removed and replaced as part of this project, unless referring to a hard ceiling. Offices that are being renovated into a TR will have the ceiling removed, but not replaced.

Reference Drawing TN603

On the above details, it shows four (4) sensor locations on each rack. Are each of these four (4) sensors to be provided as a combined Temperature & Humidity Sensor or are some of these temperature-only sensors and others humidity-only sensors?

RLF – The product description confirms the device is to measure temperature and humidity. Temperature and Humidity Sensors are to be provided on racks in the MCR only. TR racks do not require these sensors.

PDUs can be provided as “Basic”, “Metered”, or “Monitored”. On the above details, the REMARKS statement seems to imply that each new PDU must have the capability of being “monitored”. Do all the 208v PDUs for this project need to be the “Monitored” type?

RLF – All PDUs need to be “monitored”. A data cable needs to be run to each PDU during the installation.

Reference Drawing TN603

Question A - PDUs for telecommunications enclosures seem to be 120v “Basic” type as shown in Detail 12. Since they appear to NOT be “monitored” type, are temperature and humidity sensors required to be installed on any of the telecommunications enclosures?

Question B – The sensors shown in Detail 4 appear to be for Computer Room Racks only (Qty-20), what are the specifications (i.e., BOD) for temperature and humidity sensors on the telecommunications enclosures?

RLF – We received guidance that temperature and humidity sensors are not needed in TR/TE spaces. The 20 racks in the MCR would require 80 temp and humidity sensors connected to 40 PDUs.

Reference Drawing M700

On the above detail, it indicates that the rack mounted temp and humidity sensor arrays are to be used for monitoring and alarm only. Is the Temperature controls contractor required to provide four (4) individual temperature monitoring points and four (4) individual humidity monitoring points for each individual rack?

CAH – Refer to revised detail on sheet M700 issued as “Revision 2: Design Alert 13” dated 7 February 2024. Rack mounted temperature and humidity sensors are not required in TRs.

Reference Price Schedule

The price schedule for this project indicates Marion, IL VAMC. Should this be changed to Memphis VAMC?

VA – The location above the price schedule is incorrect. The correct location is the Memphis, TN VAMC.

Reference Tax Exemption Certificate

Can the VA confirm that the SC-PDU-3’s are only for the racks in the MCR and not the TRs?

RLF – I need additional information to answer this question. I believe this may have been answered by a previous response that provides a total PDU count.

Reference AE001, Detail 2 TEMPORARY WALL CONSTRUCTION ELEVATION This elevation says to provide a TRIATEK MONITOR in the wall. Below is from the supplier website:

“The Room Differential Pressure Sensor is a sensitive mass air flow sensor designed to measure the pressure differential between a reference space (like a hallway or ante room) and the monitored space (like a lab or patient isolation room). It is installed the door. The Room Differential Pressure Sensor communicates with FMS-2000C or FMS-2000M and the Venturi air valves. They work together to provide a rapid response to changing conditions to help maintain a protective environment. This sensor provides real-time measurements to the room displays so you can be confident your current room status is accurate.”

Questions: Can the VA confirm that this type of sensor is required, and it must also include communicating with FMS-2000C or FMS-2000M? Who is to provide the comm components and are they to connected to 24 VAC or 24 VDC and monitored by Johnson Controls as the website suggests?

ES – VA to provide response.
