The contractor and government shall be required to work together to facilitate a schedule in these cases. After hours work requires prior approval of the lab COR and the hours shall be charged as overtime hours.

Repair actions are classified as follows:

1.4.2. Emergency Work Request.

The contractor shall respond to the site within two (2) hours of Government notification to the contractor in order to fix the problem or mitigate the circumstances till the problem can be fully resolved.

1.4.3. Urgent Work Request. A work request is urgent when a piece of equipment or system, deemed as critical to the user’s mission, needs service due to failure. The contractor shall respond to the site within twenty-four (24) hours of Government notification to the contractor in order to fix the problem or mitigate the circumstances till the problem can be fully resolved.

1.4.4. Routine Work Request. A work request is routine when a piece of equipment or system, deemed non-critical to the user’s mission, needs service due to failure. The contractor shall respond to routine work requests within three (3) workdays of Government notification to the contractor in order to fix the problem or mitigate the circumstances till the problem can be fully resolved.

1.4.5. Non-Duty Hours. The contractor shall receive non-duty hour calls through the CE Service Call Desk. The contractor shall respond to the site within two (2) hours of Government notification to the contractor in order to fix the problem or mitigate the circumstances till the problem can be fully resolved.

The contractor shall furnish the COR a list of personnel authorized to respond to emergency and urgent work requests and their phone numbers within five (5) workdays after contract start and update listing as required by contractor personnel changes. Following a response to a non-duty hours request the contractor shall submit a WR request to the CO the next workday.

1.4.6. Repair vs. Replacement. Repairs costing in excess of seventy-five (75%) percent of the replacement cost of the individual item of equipment or repairs that the contractor determines are uneconomical shall be referred to the COR for determination of what action is to be taken. Repair includes restoration of equipment or components to a condition that the equipment may be used effectively for its designated purpose. Restoration includes overhaul, replacement, reprocessing, or repair of constituent parts or materials that have deteriorated by the action of the elements or wear and tear and which cannot be corrected through maintenance.

1.4.6.1. The government may choose to replace equipment when repairs cost less than seventy-five (75%) percent of the repair cost. Under such circumstances, the CO will request the contractor to replace the equipment in lieu of making repairs.

1.4.7. Repairs/Replacements Costing Less Than $3,500 in Materials and/or 15 Labor Hours. The contractor shall respond to the work request and make the required repairs/replacements and submit an itemized bill through his normal invoicing process. Labor shall be charged to the government purchased labor hours. Parts, materials, equipment rentals, subcontractors, etc. shall be billed to the customer’s GPC. During repair/replacement work, if contractor anticipates an upward deviation of material costs to $3500 or greater, or estimated labor hours greater than 15 hours the contractor must seek additional approval from the COR for continuance of work.

1.4.8. Repairs/Replacements Costing $3,500 or Greater in…
