C. SCOPE OF WORK

Preventive Maintenance. Service shall be executed per the general guidelines listed in

Section D and the Manufacturer’s Operations & Maintenance (O&M) manual for each specific make and model.

NOTE: Due to the anticipated renovation of the HVAC system serving the South

Building, no Preventative Maintenance work on the systems described for that building will be required in the Base Year. Final drawings and equipment information for those systems will be provided prior to exercising Option Year 1.

Preventive maintenance inspections are to include necessary replacement of all lubricants, coolant, belts, hoses, and minor parts (less than $300 per item).

Emergency Calls. The contractor shall respond to emergency repair calls within 24 hours after notification at any time (during and/or after business hours, 8am – 5pm, including weekends and holidays). Only the Contracting Officer, Contract Specialist or the

Contracting Officer Representative are authorized to make an emergency call. The contractor shall prepare and submit a written report within two (2) business days after the emergency repair. The report shall include the date and time of the service call, the repairs performed, and the name of the technician performing the repairs.

Repairs. If during routine maintenance or an emergency call it is discovered repairs are needed, the contractor will notify the CO or designated representative of repairs needed and associated cost of repairs not covered in the basic service contract. No work is to be done to address the repair without authorization from the CO. The Government reserves the right to pursue repairs through any procurement means available and/or required by Federal regulation.

Parts requiring replacement during scheduled maintenance visits or emergency calls that are more than $300 per individual item are eligible to be reimbursed under the reimbursable parts line item but will require COR approval prior to replacement. Reimbursement is based on the actual cost of parts and materials to the Contractor; profit and overhead will not be allowed.

Requests must be accompanied by a supplier invoice that would also be uploaded in IPP with the vendor invoice.

In the event that a single part or multiple parts for a single unit must be replaced that exceed

$2,500.00 in total, the Contractor shall procure the items/services on a competitive basis or provide justification, if there is lack of competition.

Parts not readily available could be scheduled for replacement during the next scheduled visit based on COR approval if determined immediate replacement is not critical.

All parts will be of equal quality or better than replaced parts. Discounts and rebates on items provided to the Contractor shall be credited to the Government. All purchase documents shall be made available for the Government’s review and audit.

The Government reserves the right to purchase parts through any procurement means available and/or required by Federal regulation. These parts would be provided to the contractor for replacement on the next scheduled visit.
