Engineer may elect due to a state of emergency to allow multiple concurrent Burn-In periods to occur
based on a breakdown of the project at his/her discretion (e.g., DMS sites, Camera sites, individual
sites, etc.).
An equipment failure during the Burn-In Period is defined as a condition where a component stops
functioning. A system failure is defined as a condition under which the system is unable to function as
a whole or in significant part to provide the services as designated. While a single component failure
may not constitute a system failure, chronic failure of that component or component type may be
sufficient to be considered a system failure as determined by the Engineer. What constitutes a chronic
failure shall be agreed upon in writing by the Contractor and the Engineer prior to beginning the Burn-
In.
ITS electronic equipment which has repeated failures (repeated failures are defined as more than
two in a thirty-day period) during the Burn-In Period shall be replaced by the Contractor at no cost to
the Department. Field Test must be conducted for the new equipment and the Engineer’s acceptance
shall be obtained for said testing. Upon satisfactory completion of the testing, the Engineer will provide
written authorization to commence with a thirty (30) day Burn-In Period for the new equipment.
Final acceptance shall mean successful completion of Burn-In to the satisfaction of the Engineer.
If any equipment or device fails to complete the thirty (30) day Burn-In Period, the Burn-In Period
shall be suspended and time charges resumed. The Burn-In Period will not be restarted except when
the following has been met:
• Repairs to the malfunctioning equipment/device have been satisfactory completed; and,
• The repaired equipment/device is to be re-tested and proven to be properly functioning.
Only upon the Engineer’s acceptance of the repaired equipment/device, will the Contractor be
allowed to resume the Burn-In Period.
General communication outage or failure due to hardware is considered a system failure in any
case. Communication failure due to a minor component may not be a system failure. Specifically
exempted as system failures are failures caused by accident, natural disasters, or other external forces.
The Engineer will advise the Contractor in writing when it considers that a system failure has occurred
or a chronic failure exists.
Each system failure during this Burn-In Period shall require restarting the clock plus an additional
two (2) calendar days of successful operation prior to being eligible for final acceptance (i.e., if there
are two system failures during the initial 30 day period, the period would be increased by 4 days).
Successful completion of the Burn-In Period shall occur at the end of thirty (30) complete calendar days
of operation without a system failure ascribable to hardware, software, or communications
components.
The Contractor shall generate Test Result Documentation for the Burn-In which shall include at a
minimum:
• Documentation for any ITS electronic equipment failures, system failures or communications
failures;
• Document corrective actions taken by the Contractor for equipment repairs;
• Any re-test documentation for the repaired or replacement equipment;
• All manufacturers’ ITS electronic equipment protocol control software; and,
• All manufacturers’ configuration and diagnostic software along with licenses transferred to
the Department.
This Test Result Documentation shall also consist of the minimum applicable information as
specified within Acceptance Test of the Specification. Once the Burn-In Period is successfully
completed, the Contractor shall submit the complete package of the Test Result Documentation for
Burn-In to the Engineer for acceptance. The Engineer’s acceptance shall be in writing, which
acknowledges receipt of the Test Result Documentation along with verification that Burn-In was
successfully completed.
If equipment or device failures occur, the Engineer may request for the Contractor to submit
advance copies of the Burn-In Test Result Documentation so as to gain insight to the equipment
problems and any corrective actions taken to date.
