Design Requirements
SECTION 27 10 00
Add to section 1
- References: ADD International Code Council (ICC) International Building CodeI (IBC) for seismic zoning and equipment bracing.
Add to 1.2:
Where protective distribution systems are required, SIPRNET Technical Implementation Criteria (STIC), September 2013, provide the guidance for the installation of protected distribution systems (PDS) (HOLOCOM, Wiremold, EMT, PDS systems are all identified as allowable PDS). Which system to be used is determined by many factors i.e., location, threat, protection required, security available, and cost. Each project is analyzed, and proper technical solution will be determined. The NEC does not make these decisions. A review of referenced document for full explanation recommended.
Add to 1.2:
Field Radio Antenna: Coordinate with contracting officer to determine if a field radio antenna is required by the building occupant. If required, provide a 2-inch raceway from the Duty Office (or location designated by the User) to the exterior of the building with a grounding bushing at the interior and a weather head at the exterior and coax cable for a field radio antenna connection. Coordinate installation requirements with the User.
1.3.4 Telecommunications Rooms (TR)
Follow the general requirements of Chapter 2 with the following additional requirements.
Minimum dimensions – 10 feet 8 inches (3.25 meter) by 12 feet (3.6 meter), meeting all
TIA-569-C standards with the below exceptions.
- Base sizing of room on the additional systems requirements of the service space such as BMS, ACMS, IDS, fire-alarm panels, and A/V equipment.
- Provide a minimum of two standard 19-inch cabinets per TR. Equipment racks will be used by exception due to physical security requirements and other specific facility requirements.
- In facilities or structures that only require the minimum infrastructure to the EF, one cabinet may be used, and the room resized appropriately.
- Mount all cabinets to the permanent floor, centered in the TR to meet ADA access requirements. Treat floors, walls, and ceilings to eliminate dust by providing eggshell or semi-gloss paint finish, light in color to enhance room lighting. Provide one wall outlet installed at or near the entry door for emergency or primary voice communications.
Add to 1.5 - Cable test reports. Include the model/serial number of the test equipment, calibration certificate, technicians name and certificate of training on test equipment/device. Hand generated reports are not acceptable. The JBLM DPW/NEC will require insertion loss tests for all telecommunications cable (TIA-568-C.2)
Add 1.10.2.c Elevator Control System: Data outlets for Elevator Control System network connections shall be installed outside the elevator equipment enclosure. The data outlet shall consist of a fully terminated connection in a customer face plate. The customer faceplate shall be protected from tampering through the installation of a cover/enclosure. The cover/enclosure shall be labeled the same as the customer face plate. Coordinate with the JBLM NEC Plans Branch for design/configuration and the NEC JBLM TIA-606 Labeling Scheme.
1.10.2 d) Wireless AP - Requires Category 6A (CAT6A) Cabling.
Coordinate any use of CAT6A and higher rated cabling and associated cost changes with all stakeholders, technical reviewing authority, telecommunications manager, building occupants and other service specific authorities. Components used in a CAT6A system (i.e., outlets, patch panels, and patch cables) must also be CAT6A rated. When the requirements warrant the use of CAT6A and funding permits, activities may utilize shielded twisted pair (STP) cabling as this reduces the probability of alien crosstalk. Include the cable tray and conduit or J-hooks to support the cable connected to the WAP. The use of “J” hooks, flexible cable tray(s), and alternative support systems specifically certified for the cable utilized is permissible to support the WAPs from the cable tray. Do not exceed a 50 percent fill ratio for the “J” hooks. Support horizontal cabling to distribution areas in cable tray(s).
Add to part 2
- Facility Telecommunications
2.1.a General Coordinate with the DPW, NEC Plans Branch Chief and the IT Project Manager during the design development process, as discussed in Section 01 33 16, Design after Award. The contractor's RCDD shall provide a whole building telecommunications design to include the NEC Main Telecommunications Room (Telecommunications Entrance Room) subsequent required Telecommunications Rooms on each floor (stacked configuration if multi-story building). Drawings shall include conduit sleeves, grounding system, fire rated backboards on all walls, air conditioning, etc. in addition to the interior cable distribution system to comply with UFC 3-580-01. Confirm with the User and provide Army convenience telephones on each floor if required. Coordinate with telecommunications manager and appendices for any additional service-specific labeling or administration requirements. Color-coding of telecommunications infrastructure and components is recommended, but not required. Drawings shall be IAW the UFC 3-580-01 (Chapter 2 and Chapter 4), I3A TC (3.0), TIA 606-B, and BICSI TDMM. Telecommunications drawings are required to be numbered IAW TIA 606-B C.2 T-Series drawings (T-0, T-1, T-2, T-3, T-4, AND T-5). Adherence to this requirement will be provided for ease of NEC internal review processes and maintain standardization for maintenance, troubleshooting, and costing telecommunications maintenance bench stock across the entirety of the JBLM AOR.
Telecommunications Inside Plant/Outside Plant (ISP/OSP) Check Sheet: JBLM NEC shall provide to USACE the updated JBLM NEC Telecommunications ISP/OSP process check sheet to promote ease of planning for telecommunication installation planning and inspection activities (check list provided to USACE at project kickoff meeting or prior upon request): List not all inclusive, see subject check sheet for complete details of items listed below:
ISP
- ISP drawing reviews.
- Review product submittals
- Review ground tests.
- Review cable test plans.
- Witness cable testing.
- Elevator phone installation scheduling
- Switch installation scheduling
- Attend pre-construction meetings for each milestone.
- Periodic spot inspections.
- Punch list creation / review / backcheck.
2.1.b) Provide a cable pull-through in the main NEC telecommunications room to a dedicated room with space on the telephone back board for commercial telephone and cable TV service providers. Commercial telecommunication providers will furnish and install their entrance cables and make connections to their equipment under separate contract with the Government. Coordinate with these providers and allow them access to perform their work. CATV cables may pass through the NEC telecommunications room only. No terminations in the NEC telecommunications room are allowed. The contractor shall coordinate all requirements for CATV with the commercial provider and shall provide a complete and usable distribution system in each building that complies with service provider standards.
2.1.c) The Contractor shall furnish and install interior cables from cable television outlets and from commercial telephone outlets that may be required for the facilities in this project back to the appropriate demarcation point.
2.1.d) Commercial Telecommunications providers will make the connections to their equipment under separate contract with the Government.
2.1.e) Horizontal Distribution in Small Facilities and Renovations In new construction involving small, mixed use (non-administrative) facilities, or construction projects involving renovation of existing buildings, use of J-hooks, flexible cable tray, and alternative support systems specifically certified for Category 6 cable is permissible, though not desirable. In renovation projects where access to the walls for installation of conduit and outlet boxes is not possible, or where historical requirements prohibit the alteration of the building structure, surface mounted non-metallic raceway may be used. JBLM NEC preference is the contractor provide cable runways in telecommunications rooms and wire basket cable tray for horizontal distribution with minimum 1” conduit from tray to each cable TV, voice, and data outlet.
2.1.f) Coaxial cable and Category 6 cable shall not be installed in the same conduit.
Change 2.3.2.1 to read: Provide CAT 6 cables that are UL-listed for wet environments where cables are routed in conduits installed inside or below slab-on-grade concrete floors. CAT6 voice cables shall be terminated on Rack-Mount Cat6 110, 568B, RJ45 Ethernet, TAA Compliant Patch Panel.
Add 2.4.2.d Seismic Bracing: Brace or anchor equipment to resist horizontal forces acting in any direction per the site class and seismic use group as defined in the ICC IBC.
Add to 2.5.1 Cable colors shall be blue for data, white for voice, red for SIPRNET, and yellow for JWICS.
Add to 3.1.5 Cable Tray Installation (TIA-569-D) - Trays may be divided with a barrier to allow for physical separation between power and conductive telecommunications cables. Power and telecommunications cables shall be installed per electrical code. A minimum of 200 mm (8 in) access headroom shall be provided and maintained above a cable tray system or cable runway. The recommended access headroom above cable trays and runways is 300 mm (12 in). Care shall be taken to ensure that other building components (e.g., air conditioning ducts) do not restrict access therefore JBLM NEC requires 10 inches on at least one side of cable tray/basket, if possible, for add moves and changes.
