1.4.1. General. The contractor shall provide all labor, supervision, equipment, tools, materials, and all other services required for the execution and completion of service calls, or as referred to from here on, work authorizations (WAs) to provide repair, replacement, and minor upgrades to equipment. The contractor shall perform 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 replacement 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. The requirement for equipment repair may be identified by the contractor. Within two working days, the contractor shall notify the applicable COR and Lab COR that repairs need to be made. Repair requirements may also be identified by government personnel. In both cases, personnel who are approved to place calls against the contract by the CO, will notify the contractor of the requirement and request they open a WA. The contractor shall prepare a WA, and the CO verbal or written approval of the WA shall constitute for the contractor to proceed. A small amount of repair and/or replacement activities shall be required to be performed after normal hours due to on-going testing and instances where equipment shut-down would impact the user’s mission. The contractor and government shall be required to work together to facilitate a repair and/or replacement schedule in these cases. After hours work requires prior approval of the CO and the cost shall be charged as overtime hours, where applicable.

Repair actions are classified as follows:

1.4.2. Emergency Work Request. A work request is an emergency when a piece of equipment, deemed as essential to the user’s mission, needs service due to failure. The contractor shall respond to emergency work requests within two (2) hours of verbal approval by the CO.

1.4.3. Urgent Work Request. A work request is urgent when a piece of equipment, deemed as critical to the user’s mission, needs service due to failure. The contractor shall respond to urgent work requests within twenty-four (24) hours of verbal approval by CO.

1.4.4. Routine Work Request. A work request is routine when a piece of equipment, 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 a WA being approved by the CO.

1.4.5. Non-Duty Hours. The contractor shall receive non-duty calls through the CE Service Call Desk.

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 CO for determination of what action is to be taken. The CO shall request the contractor repair, replace, or take no action on the equipment.

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 $5,000.00 or Less. The Lab COR will request the contractor prepare a WA for these requirements. The CO must approve the WA. The contractor shall make the required repairs/replacements and submit an itemized bill through his normal invoicing process charged to the firm fixed price labor CLIN and the Time & Material CLIN.

If the contractor determines a particular WA for minor repairs involves real property and meets the criteria specified in DFARS 222.402-70, the contractor may request Davis-Bacon Wage Rates by submitting a written proposal and cost estimate for the work to the CEPCOR. The CEPCOR shall review the request and forward it to the CO with recommendations. The CO shall make a determination if the criteria specified in DFARS 222.402-70 are met and Davis-Bacon wages apply. The contractor shall prepare an estimate detailing material costs, equipment rental costs, labor costs by trade and time. The estimate shall be presented to the Lab and CE COR for signed approval by both to authorize the work. Once an estimate is provided by the contractor and signed approval has been given the work shall proceed. The contractor shall make the required repairs/replacements and submit an itemized bill, through his normal invoicing process, for the labor hours. The labor hours shall be charged to the firm fixed price labor CLIN. The materials, parts, sub-contractor fees and rental costs shall be charged to the customer’s

GPC.
