Cable Systems Installation:

Install system cables in cable duct, cable tray, cable runway, conduit or when specifically approved, flexible NEC Article 800 communications raceway. Confirm drawings show sufficient quantity and size of cable pathways. If flexible communications raceway is used, install in same manner as conduit.

Coordinate outside plant and backbone cables to furnish number of cable pairs for system requirements and obtain approval of COR and IT Service prior to installation.

Bond to ground metallic cable sheaths, etc. (i.e. risers, underground, horizontal, etc.).

Install temporary cable to not present a pedestrian safety hazard and be responsible for all work associated with removal. Temporary cable installations are not required to meet Industry Standards; but, must be reviewed and accepted by COR, IT Service, FMS and SMCS 005OP2H3 (202-461-5310) prior to installation.

Patient Bedside Prefabricated Units (PBPU) Installation:

Under no circumstances, proceed with installing PBPU without written approval of PBPU OEM and specific instructions regarding attachment to or modifying of PBPU.

Maintain UL integrity of each PBPU. If installation violates UL integrity, obtain on site UL re-certification of violated PBPU at the direction of COR.

Labeling:

Industry Standard: Provide labeling in accordance with ANSI/TIA-606-B.

Print lettering of labels with laser printers ; handwritten labels are not acceptable.

Label both ends of all cables in accordance with industry standard. Provide permanent Labels in contrasting colors and identify according to system “Record Wiring Diagrams”.

Termination Hardware: Label workstation outlets and patch panel connections using color coded labels with identifiers in accordance with industry standard and record on “Record Wiring Diagrams”.

FIELD QUALITY CONTROL

Interim Inspection:

Verify that equipment provided adheres to installation requirements of this section. Interim inspection must be conducted by a factory-certified representative and witnessed by COR.

Check each item of installed equipment to ensure appropriate NRTL label.

Verify cabling terminations in telecommunications rooms and at workstations adhere to color code for T568B pin assignments and cabling connections comply with TIA standards.

Visually confirm marking of cables, faceplates, patch panel connectors and patch cords.

Perform fiber optical field inspection tests via attenuation measurements on factory reels and provide results along with manufacturer certification for factory reel tests. Remove failed cable reels from project site upon attenuation test failure.

Notify COR of the estimated date the contractor expects to be ready for interim inspection, at least 20 working days before requested inspection date, so interim inspection does not affect systems’ completion date.

Provide results of interim inspection to COR. If major or multiple deficiencies are discovered, COR can require a second interim inspection before permitting contractor to continue with system installation.

Do not proceed with installation until COR determines if an additional inspection is required. In either case, re-inspection of deficiencies noted during interim inspections must be part of the proof of performance test.

Pretesting:

Pretest entire system upon completion of system installation.

Verify during system pretest, utilizing the accepted equipment, that system is fully operational and meets system performance requirements of this section.

Provide COR four copies of recorded system pretest measurements and the written certification that system is ready for formal acceptance test.

Microduct Tests:

Furnish COR, obstruction and pressure test data for each microduct installed. Complete pressure and obstruction tests per manufacturer’s recommended procedures prior to installing fiber and ensure 100 percent of all microducts are compliant with manufacturer.

Complete microduct pressure testing before proceeding with end-to-end microduct obstruction testing.

Notify COR at least one week in advance of test date so that Government and design professional may be present to witness testing.

Maintain close contact with chosen and technically approved OEM and SMCS 005OP2H3 throughout installation, testing and certification process.

Acceptance Test:

After system has been pretested and the contractor has submitted pretest results and certification to COR, then schedule an acceptance test date and give COR 30 days' written notice prior to date acceptance test is expected to begin.

Test only in presence of a COR.

Test utilizing approved test equipment to certify proof of performance.

Verify that total system meets the requirements of this section.

Include expected duration of test time, with notification of the acceptance test.

Verification Tests: - (NOT USED) Performance Testing:

Total System Acceptance Test: -(NOT USED)

MAINTENANCE

Accomplish the following minimum requirements during one-year warranty period:

Respond and correct on-site trouble calls, during standard work week:

A routine trouble call within one working day of its report. A routine trouble is considered a trouble which causes a system outlet, station, or patch cord to be inoperable.

Standard work week is considered 8:00 A.M. to 5:00 P.M., Monday through Friday exclusive of Federal holidays.

Respond to an emergency trouble call within six hours of its report. An emergency trouble is considered a trouble which causes a subsystem or distribution point to be inoperable at any time.

Respond on-site to a catastrophic trouble call within four hours of its report. A catastrophic trouble call is considered total system failure.

If a system failure cannot be corrected within four hours (exclusive of standard work time limits), provide alternate equipment, or cables within four hours after four-hour trouble shooting time.

Routine or emergency trouble calls in critical emergency health care facilities (i.e., cardiac arrest, intensive care units, etc.) are also be deemed as a catastrophic trouble.

Provide COR a written report itemizing each deficiency found and the corrective action performed during each official reported trouble call. Provide COR with sample copies of reports for review and approval at beginning of total system acceptance test.
