CD-ROM, in AutoCAD Release 2000 format. Items to be included as record
drawings and information include the following:
- Copper feeder cable information to be shown is: cable type, size,
gauge, year installed, cable number, pair counts, distance(s) and any
and all splice location(s).
- Fiber feeder cable information to be shown is: type cable, size,
cable number, fiber count, distance(s), splice locations, length of
piece.
- Terminal information to be shown is: terminal identity, quantity
and type of protectors or unprotected, quantity and type termination
blocks, cable and pairs entering and/or leaving.
- Riser cable information to be shown is: cable
type, size, gauge, year installed, length, splice points, cable number,
pair count(s).
Architects and contractors have come to accept the rigid industry standards
that voice and data communication systems require. For the most part,
specialized skill sets that are required for the design and installation
of these systems now tend towards commodity status.
However, unlike power cabling systems, the technology of telecommunications
cabling continues to advance dramatically. For this reason the District
must specify some industry accepted certifications and credentials to
guarantee the quality of the installation. Additionally the installed
systems must be documented in a way that allows for minimal ongoing labor
in the maintenance and management of the installed system.
Codes and Standards: The
District’s communications
systems follow the codes and standards set forth in the ANSI/TIA/EIA
Telecommunications Infrastructure Standards. Additionally, the FCC, NESC,
NFPA and IEEE and BICSI’S Telecommunications Distribution Methods
Manual is to be used as a reference. In addition the following
industry guidelines must be adhered to by the contractor:
- Electronic Industry Association (EIA/TIA) wiring standards for commercial
buildings (EIA/TIA 568-B) and Wiring Spaces (EIA/TIA 569).
- EIA/TIA Technical Specification Bulletins for Category 6 wire specifications.
- EIA/TIA Technical specification Bulletins for Category 6 hardware.
- Commercial Building Grounding and Bonding Requirements (TIA/EIA-607).
- Fiber-Optic Inter-repeater Link Standard (FOIRL)
- IEEE 1000Base Fiber-optic Standards
- Underwriters Laboratories
- Title 24 – State of California
Code of Regulations
- City or County Electrical Code as applicable
- Occupational Safety and Health Act (OSHA) Standards
The contractor will furnish without extra charge any additional material
and labor which may be required for compliance with these laws, rules,
and regulations, even though the work is not mentioned in these particular
specifications.
Specifications: These
standards include general specification data for the District and
are indicative of the “types” of
systems that the District requires in all its buildings. These standards
are NOT to be used as the final specification or bid document for any
specific new construction. It is to be used as a starting point in
a process of collaboration between the architect/designer, the occupant,
and the District’s central telecommunications department of Information
Technology Services (ITS). Detailed requirements for the specific
project at hand will depend on the unique purpose of the space(s) of
that project and shall be supplied during the design phase of the space
in that collaboration.
Contractor is required to adhere
to the following parameters whether or not existing equipment has been
placed by contractor and/or others. Contractor
will notify ITS of any of the following requirements that cannot be met
prior to commencement of installation:
- The maximum length of horizontal
cabling from nearest closet shall not exceed 295 feet as per EIA/TIA
568B – Category 6 Cabling
Standards. Contractor will notify ITS prior to commencement of
any installation not meeting the 295-foot maximum distance limitation.
- UTP cabling must conform to a 6 foot separation requirement from
main power panels, switch gear and/or starter motors.
- All power feeds crossing the path of the UTP cables at right angles
must be a minimum of 12 inches in distance from the UTP cables.
- UTP cables will be installed a minimum of 5 inches from fluorescent
lighting.
- The cables shall be placed at a minimum of 18 inches above the ceiling.
- The cables are to be as accessible as possible.
- Backboards must be squarely cut, sanded and painted with two coats
of fire retardant paint.
- All conduit installation must meet all local and state building codes.
- Debris, boxes, leftover cables,
and trash must be removed from construction sites daily. Area must be left broom clean at the end of each
day. No debris or work material may be left in areas that have
student access unless the affected area is marked with cones, tape,
or temporary fencing.
- Pull conductors together where
more than one is being installed in a raceway. Cable bundles in suspension systems or on wallboards
must be tie-wrapped every 4 feet. Strapping to any other wire
(e.g. lighting ceiling grid, etc.) will not be permitted. Station
wire cannot be attached to electrical conduit, gas or sprinkler piping,
or other code-restricted items.
- Use pulling compound when necessary; pulling compound must be a water-base
pulling lubricant that will not deteriorate cable or conduit.
- No cabling is allowed to rest on any ceiling tile or suspension system
unless specifically authorized by ITS.
- All cable/cabling shall be kept 30 inches away from any heat source;
i.e., steams valves, etc.
- Cables shall be pulled with no sharp bends, kinks, or impact damage
to the sheath.
- Cables shall not be pulled across
sharp edges. Cables
shall not be forced or jammed between metal parts, assemblies, etc.
- Cables shall not be pulled across
access doors and pull box covers. Access
to all equipment and systems must be maintained.
- Insulation shall be removed to expose shielding and conductors to
the exact length required by manufacturer for proper termination of
plugs and pins and as specified in EIA/TIA 568/569.
- Pins and plugs, upon termination, shall not be damaged in any way.
- All equipment communications racks must be properly anchored to walls
and floors and grounded to the building ground grid (not to water pipes,
etc.).
- Cable splicing will not be permitted at any point within a cable
run.
- Conduits will not be filled to a greater ratio than that specified
by the EIA/TIA 569 standards
- Cable mountings on backboards
will be installed efficiently, to minimize the backboard space consumed. All
cables will be routed at right angles, in accordance with the bend
radius specifications for the type of cable being routed.
Bid Document: It is expected that a result of this
collaboration shall be the creation by the Design Team of a bid-quality
document that contains commonly accepted and standard language of the
industry, such as the Division 16 standard specifications prepared by
the Construction Specifications Institute (SpecText) and the American
Institute of Architects.
