During this burn-in period the Contractor shall be responsible for the full maintenance of the newly installed equipment. However, no separate payment will be made for the burn-in period activities and shall be included in the cost of other items. Successful completion of the burn-in period will occur at the end of three complete months of operation without a major system failure attributable to hardware, software or communications components. Each system failure during the burn-in period will require an additional month of successful operation prior to being eligible for Final Acceptance. (i.e., if there are two system failures during the initial three month period, the burn-in period would be increased to five (5) months.) Burn-In General Requirements. Determination of a system failure shall be at the sole discretion of the Engineer. 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 designed. While a single component failure will not constitute a system failure, chronic failure of that component or component type may be sufficient to be considered a system failure. Chronic failure of a component or component type is defined as 3 or more failures for the same component during the burn-in period. Components are defined as contract items or major material elements in a contract item. For electrical and electronic c ontract items, components are defined as the complete assembly of materials that makes up the contract item. Specifically exempted as system failures are failures caused by accident, acts of God, or other external forces that are beyond the control of the Contractor. However, failure of the contractor to respond to the repair request for that failure within 24 hours may be considered a system failure. The Department will advise the Contractor in writing when it considers that a system failure has occurred or chronic failure exists. If multiple system and/or chronic failures continue to occur throughout the burn-in period due to a single component type, the Contractor may be required to replace all units of that component type with a different model or manufacturer. The Contractor shall document all failures and subsequent diagnosis and repair. The repair documentation shall include as a minimum:  Description of the problem  Troubleshooting and diagnosis steps  Repairs made  List of all equipment and materials changed including serial numbers.  Update of the equipment inventory where needed. The Contractor shall provide the repair documentation to the Engineer within two (2) days of completing the repair; failure to provide acceptable documentation as required shall be reason to not approve the repair as comple te. The Engineer w ill provide acceptance or rejection of the repair and documentation within seven (7) days. The Engineer reserves the right to require, at no additional expense to the State, the presence of a qualified technical representative of the equipment and/or software manufacturers as related to the diagnosis and/or repair of any system failure. During the burn-in period the Contractor shall perform incidental work such as touching up, cleaning of exposed surfaces, leveling and repair of sites, sodding/grassing and other maintenance work as may be deemed necessary by the Engineer to ensure the effectiveness and neat appearance of the work sites. During the burn-in period the Engineer shall maintain a “burn-in period punch list” that contains required Contractor actions but that the Engineer does not define as a system failure. Each burn-in period punch list action item shall be completed by the Contractor to the Engineer’s satisfaction within seven (7) da ys of Contractor notification of the action item. During the burn-in period the Contractor is required to meet the following response times once notified there is a problem. A response is defined as being on-site to begin diagnosing the problem.  Monday thru Friday: The Contractor shall respond no later than 9:00 a.m. the following morning after being notified.  Weekends: If the Contractor is notified on Friday afternoon or during the weekend, the Contractor shall respond by 9:00 a.m. on Monday morning. During the burn-in period the Contractor shall provide all labor, materials, equipment and replacement parts to completely maintain, troubleshoot and repair all items installed under this contract. No separate payment will be made for any labor, materials, equipment, or replacement parts needed during the burn-in period. The overall burn-in period will be considered complete upon the successful completion of the burn-in time periods, the Engineer’s acceptance of all repairs and repair documentation, completion of all burn-in period punch list actions and a final inspection as described below.

656.03.2 8--DMS Final Inspection. Upon successful completion of the burn-in period,

the project shall be eligible for the DMS final inspection. The DMS final inspection will be conducted provided the burn-in period has demonstrated the entire system is operating successfully. The DMS final inspection shall include but is not limited to;  monitoring of all system functions at the TMC to demonstrate the overall system is operational  a field visit to each site to ensure all field components are in their correct final configuration  verification that all burn-in punch list items have been completed  verification that all final cleanup requirements have been completed  approval of final as-built documentation Prior to conducting the DMS final inspection, the burn-in period shall demonstrate that all requirements defined in the specifications have been met. The Contractor shall request in writing the En gineer’s approval to start the DMS final inspection a minimum of 14 days prior to the requested start date. The Engineer reserves the right to reschedule the start date if needed. The start date for the DMS final inspection cannot be prior to the successful completion of the overall burn-in period. An unsuccessful or incomplete DMS final inspection shall require a new DMS final inspection after the Contractor has made the necessary corrections. Up to 14 days shall be allowed for the Engineer to conduct a DMS final inspection. The Engineer reserves the right to require, at no additional expense to the State, the attendance of a qualified technical represen tative of the equipment and/or software manufacturers to attend a portion of a DMS final inspection. The presence of the Project Engineer and ITS Engineer or his designee is required during the final inspection. The Contractor shall be responsible for the full maintenance of all project equipment and materials during the entire time period from the successful completion of the burn-in period until Final System Acceptance is granted.
