4. Any Work that blocks roadways, access to buildings and parking lots shall require written acceptance following the requirements above for notification and acceptance.

5. OCSD lockout/tagout procedures shall be followed for isolation of equipment for

Work. OCSD will provide tags and the CONTRACTOR shall provide lockout device.

6. Prior to commencing each task, the task will have a job hazard analysis performed in which the CONTRACTOR and the ENGINEER (including OCSD inspectors and OCSD safety personnel) will be involved. All safety issues will be addressed and verification will be made that all required safety measures will be carried out and required safety equipment is available. At the work space analysis meeting, the CONTRACTOR shall submit a Work Plan that describes the number of people involved in the Work, the Work procedures, materials and equipment to be used, and any applicable Material Safety Data Sheets.

D. Asbestos:

1. It is the specific intent of these Contract Documents to exclude from the Work any and all products or materials containing asbestos. No products containing asbestos shall be incorporated in the Work.

2. It is not expected that the CONTRACTOR will encounter any existing asbestos materials. If asbestos materials are encountered during any Work, the CONTRACTOR shall promptly notify the ENGINEER in writing. Removal of existing asbestos material shall be performed by a CONTRACTOR or Subcontractor registered by Cal/OSHA and certified by the Contractors State License Board in the State of California. Copies of the certification shall be submitted to the ENGINEER. The CONTRACTOR or Subcontractor shall comply with all federal, state and local laws and regulations regarding handling and removal of asbestos materials.

3. If asbestos materials are encountered, the cost for removal and disposal shall be by change order.

3.2 INSTALLATION

A. All equipment and devices shall be installed in accordance with the requirements of the Contract Documents, NFPA 72, and the manufacturer's recommendations. Refer to the Drawings that represent an overall schematic of the fire alarm system to be provided.

B. No wiring other than fire alarm circuits shall be mixed into the fire alarm conduits. Wiring splices shall not be permitted except at device connections. Transposing or changing color coding on wiring shall not be permitted. All wiring shall be checked and tested to ensure that there are no grounds, opens, or shorts.

C. The CONTRACTOR shall integrate fire alarm systems from the automatic sprinkler system, halon suppression systems, elevator, and other alarm devices contained within the facility to assure a complete installation. The CONTRACTOR shall provide integration of the Casi-Rusco Access Control and Monitoring System interface for the installed fire alarm system.

D. The CONTRACTOR shall have the manufacturer of the fire alarm system equipment provide the services of a qualified and authorized technical representative to supervise and instruct the CONTRACTOR in installation procedures, to inspect the entire fire alarm system after installation has been completed, and assist in the performance of all field tests.

E. All electrical devices, wiring, conduits, etc. shall be provided to meet the various electrical area classification requirements as outlined in the Drawings.

F. Existing wiring shall be modified and used to interconnect the new system elements. The CONTRACTOR shall install additional wire and cable required for a functional system at no additional cost to OCSD.

3.3 PROGRAMMING

A. The CONTRACTOR shall update the system documentation to show additions an changes to the system programming required to support new installations or changes to the existing system.

3.4 DOCUMENTATION

A. The CONTRACTOR shall update the system documentation to show additions and changes to the system. The existing documentation shall be used as a starting point; the CONTRACTOR shall integrate the changes into the existing documentation. Supplements tacked onto the back are not acceptable.

3.5 SYSTEM TESTING

A. Preliminary Operational; Testing:

1. The CONTRACTOR shall conduct operational tests of each equipment item or each equipment system. The CONTRACTOR's operational test of each piece of equipment or system shall continue for not less than 24 hours without interruption.

2. All parts shall operate satisfactorily in all respects, under continuous full load and in accordance with the specified requirements, for the full duration of the test period. If any part of a unit shows evidence of unsatisfactory or improper operation during the test period, correction or repairs shall be made and the full operational test, as specified above, shall be repeated after all parts operate satisfactorily. The CONTRACTOR shall furnish all personnel, power, and all other necessary facilities for conducting the CONTRACTOR's test operations.

B. Final Operational Testing:

1. After all equipment is installed and the entire project is ready to operate, OCSD will test all equipment for a period not to exceed 7 days by operating either under actual or simulated operating conditions before Final Acceptance is given. At the discretion of OCSD, final test operation and final acceptance may be given on portions of the project prior to completion of the entire project. All defects of material or workmanship that appear during this test period shall be corrected by the CONTRACTOR. After such corrections are made, the final test operation may be run again before final acceptance a; this requirement may be waived by OCSD.

2. OCSD will supply all power, operating personnel, and auxiliaries required for this final operational test.

3. If operational completion of portions of the project will be required prior to final completion of the total project, OCSD shall have the right to take possession of and use any completed portions of the Work. Use of any completed portions of the Work shall not be construed as acceptance of those items by OCSD.

3.6 ACCEPTANCE TESTING

A. In-Progress Inspections:

1. The ENGINEER will make periodic inspection of the project in progress. One inspection will be performed at the conclusion of cable pulling, prior to closing of the false ceiling, to inspect the method of cable routing and support, and the firestopping of penetrations. A second inspection will be performed at completion of cable termination to validate that cables were dressed and terminated in accordance with TIA/EIA specifications for jacket removal and pair untwist, compliance with manufacturer’s minimum bend radius, and that cable ends are dressed neatly and orderly.

B. Final Inspection:

1. Upon completion of the project, the ENGINEER will perform a final inspection of the fire alarm system with the CONTRACTOR’s Project Foreman. The final inspection will be performed to validate that all cables were installed as defined in the Drawing package, and that the installation meets the aesthetic expectations of OCSD.

C. Test Verification:

1. Upon receipt of the test documentation, OCSD reserves the right to perform spot testing of a representative sample of the fire alarm system to validate test results provided in the test document. OCSD testing will use the same method employed by the CONTRACTOR, and minor variations shall be allowed to account for differences in test equipment. If significant discrepancies are found the CONTRACTOR shall be notified for resolution.

D. System Performance:

1. During the 3-week period between final inspection and delivery of the test and as-built documentation, OCSD will activate the fire alarm system. OCSD will validate operation of the fire alarm system during this period.

E. Final Acceptance:

1. Completion of the installation, in-progress and final inspections; receipt of the test and as-built documentation; and successful performance of the system for a 2-week period shall constitute final acceptance of the system.
