Sequence of ACU Operation #5

It is described that SD (duct smoke detector) must provide signal to FACP via DDC. But we cannot calculate the QTY and/or type of conductor because there is no detail about EXST FACP. Please provide the information about FACPs (i.e. Installation Location, OEM, Model, Type) at Bldg.949, 3076, 1524, 1300 and 1440.

As indicated in the design duct smoke detector must be directly integrated to the DDC system by means of providing signal to the DDC system and the DDC system must automatically stop the supply fan operation upon confirmation that there is smoke in the air distribution duct. The integration of duct smoke detector to FACP via DDC is not part of the project scope but at minimum for future connection ensure that DDC system has the capability to send signal to the FACP when smoke is detected in the air distribution duct.

There seems some descrepancies the QTY of network equipment listed in ONE-LINE DIAGRAM against the one described in CYBERSECURITY 5- LEVEL ARCHITECTURE OF DDC SYSTEM. There is also a point where it is difficult to determine which is the scope of work or which is existing. If possible, please provide new equipment list which we can determine new or EXST.

This is to clarify that Cybersecurity 5-Level Architecture of DDC System was portrayed as described and depicted or shown in the UFC for Cybersecurity (UFC 4-010-06), please refer to the attachement entitled "UFC 4-010-06". Cybersecurity involves an in depth or comprehensive understanding and implimentation of the logical configurations for the related control system network devices, hence a Cybersecurity Specialist is required (key person) in order to properly guide, implement and manage the cybersecurity related control systems in coordination with the Command Information Officers (CIO2 & CIO4), also emphasized in specs section 25 05 11 - 1.7.1.1 Cybersecurity Representative.

The scope is pretty much straight forward and almost typical per building. Major network components or devices were covered, drawing annotations and notes are also provided.

New network equipment made by CiSco needs periodrical maintenance service. Should we include the PMIS cost within warranty period?

Recommend including cost estimate for planning/budget purposes.

Cisco equipment will be registered into Cisco Global Enterprise Modernization Software and Services (GEMSS) formerly Joint Enterprise License Agreement (JELA). This will provide Navy with required levels of product support...but each Command will be billed separately so cost estimate data needs captured.

May we consider required software for "Cisco C3172PQ" as shown below? Are there any other special requirements?

Comprehensive Layer 2 feature set: VLAN, IEEE 802.1Q Trunking, vPC, Link Aggregation Control Protocol (LACP), Unidirectional Link Detection UDLD (standard and aggressive), Multiple Spanning Tree Protocol (MSTP), Rapid Spanning Tree Protocol (RSTP), spanning-tree guards, and Transparent VLAN Trunk Protocol (TVTP)

- Security: Authentication, authorization, and accounting (AAA); access control lists (ACLs), Dynamic Host Configuration Protocol (DHCP) snooping, storm control, private VLAN (PVLAN), and configurable Control- Plane Policing (CoPP)

- Management features: Cisco Data Center Network Manager (DCNM) support, console, Secure Shell Version 2 (SSHv2) access, Cisco Discovery Protocol, SNMP, and syslog

- Layer 3 IP routing: inter-VLAN routing (IVR), static routes, RIPv2, ACLs, OSPFv2, EIGRP stub, Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP), and Unicast Reverse-Path Forwarding (uRPF)

- Multicast: PIM SM, SSM, and MSDP

Previously commented on this...Cisco C3172PQ is a Data Center level model. Consideration of Catalyst series model such as the C90300-24P-A being proposed in SCADA project would be a more cost efficient model to meet the requirements.

Salient characteristics are listed below:

Ethernet network IP switch - Climate-controlled environment

- Key Features:

i. Location: Lockable ICS cabinet in the main GTR

ii. Form Factor: Rack-Mountable

iii. Minimum Required Protocol Support: CDP, EIGRP

iv. Software-Defined Access Compatible

v. Stackable

vi. Advanced Switching Layer 3

vii. Managed-type

viii. Trade Agreements Act (TAA) compliant

ix. Listed on DISA’s Approved Products List Integrated Tracking System (APLITS) or National Information Assurance Partnership

May we consider the EXST equipment seems like router at Bldg.971 (Not Equipment #9) is out of scope in this project? If so, please provide the information about this equipment such as specification, connection method and so one.

This is to clarify that the equipment or device in drawing T602 beside equipment #9 is the Existing Cisco 4510 R+E. This was identified as the Control System Platform Enclave (CSPE) in coordiantion with the Command Information Office (CIO). Please refer to the related drawing TH601 attached herewith entitled "BLDG 971". Thorough coordination with the Command Information Office (CIO) and Base Communication Office (Navy's Telecommunications Manager) is a must in order to established the network or circuit through cable patching. Also, Cybersecurity requires a Cybersecurity specialist (key person) in order to properly guide, implement and manage the cybersecurity related control systems in coordination with the Command Information Officers (CIO2 & CIO4).

There seem no drawings that show the specific location for ACM / Lead to be removed. If these removal work is included in this contract, please clarify the ACM/lead locations and the estimated quantity in order for us to make quotation.

The removal of ACM or lead pertains or is associated only to the drilling of wall when installing new conduit in order to protect the workers and inhabitants of the facility. However, this project does not refer to the removal of all ACM or lead in all locations. Please use the design drawings and Environmental Report to assess the location and quantity. The environmental report should be included in the design package.

Regarding the replacement of existing wiring, should the wiring conduit be replaced at the same time as the wiring replacement?

Or if the existing conduit can be reuseful, can it be reused?

It is recommended to replace the conduit with new. However, if it is difficult to install new conduits due to existing site conditions or unforseen site conditions, it is permitted to reuse existing metal conduits.

Regarding the temperature sensor for outside air temperature, there's a possibility it may not be able to take in the outside air when ACU stopped, so we would like to set 1 sensor for the outside temperature and humidity on the outside of the building instead of setting temperature sensor for each ACU.

Modification to provide 1 temperature and humidity sensor on the outside of the building instead of setting temperature sensor for each ACU is acceptable.

There are 2 sensors, but is it possible to set only 1 sensor since the measurement points and the purpose are the same?

As indicated in the schematic diagram there are two measuring points with different purposes one is to modulate which is the two way motorized modulating valve and the other one is to open/close which is the motorized ball valve.

Same as the above

All control valves have spring return function, does it mean it is normally open (all bypass when closed) when spring return is actuating with 3-way valve?

This means a "fail-safe open position" actuator returns to a pre-set home position when power is removed from the actuator.

There seems some descrepancies the QTY of network equipment listed in ONE-LINE DIAGRAM against the one described in NETWORK ARCHITECTURE OF DDC SYSTEM (For further information, please refer to the yellow highlighted portion described in the attached QTY sheet).

Please clarify which should be the priority for making the quotation.

This is to clarify that Cybersecurity drawings are shown as intended based on or as per UFC for Cybersecurity (4-010-06).

Consulting a Cybersecurity specialist with regards to this matter is highly recommended in order to fully understand the concept and guidance for implementation. Either way, as part of the requirement, Cybersecurity Representative is emphasized as specified in section 25 05 11 - 1.7.1.1. Cybersecurity is as much as priority as telecommunication equipment or devices.

Cybersecurity and Telecommunications are two distinct disciplines. TA602-603, TB602-603, TC602-603, TD602-603, TE602-603, TF602-603 are mainly Cybersecurity related drawings.
