Maintenance, Service And Repair For Emergency Back-Up Generators At Various Developments Citywide

SCOPE OF WORK
The scope of work includes quarterly and annual preventive maintenance and will also include any repair work needed to ensure the equipment is maintained in good order. NYCHA currently operates ninety-three (93) generators across our portfolio and will add one hundred and eighty-nine (189) generators over the course of the next two to three years.
1. Quarterly and annual preventive maintenance.
(a) Establish a preventive maintenance schedule for quarterly and annual preventive maintenance. This schedule must be submitted prior to the upcoming quarter and approved by a NYCHA Administrator. Annual maintenance can be incorporated into one of the quarterly maintenance periods.
(b) All work shall follow the manufacturer’s specific equipment maintenance and service guidelines as per operating manuals.
(c) Whenever Generator Maintenance is performed, the service technician shall provide the Contract Administrator with a detailed preventive maintenance report detailing the work completed. This report will be submitted with the vendor’s invoice.
2. Repair Work:
(a) Prior to the commencement of Repair Work of equipment still covered by the manufacturer’s warranty, the Vendor or its subcontractor(s), must provide to the satisfaction of the Contract Administrator, a copy of its current certification by either Generac to repair a Generac generator, or Caterpillar to repair a Caterpillar generator. This requirement does not apply to the repair of any equipment that is no longer under warranty.
(b) The Vendor shall advise the Contract Administrator of any necessary repairs and an approximate cost to complete the repairs if those repairs fall outside of the Minor or Major Preventative Maintenance schedule. This is for work discovered or recommended while the vendor is performing either quarterly or annual maintenance. The Contract Administrator will review and approve all repair work proposals.
(c) Inspect, assess and repair generators as needed or upon request by a NYCHA Administrator or designated personnel. Any time a vendor is called out on a non-emergency basis to inspect, assess and repair a generator the vendor will submit a proposal for both the assessment and any repair work needed to include material. The proposal will be reviewed by the NYCHA Administrator.
(d) Any time a vendor is called out on an emergency basis to inspect, assess and repair a generator the vendor will submit a proposal for both the assessment and any repair work needed to include material. The proposal will be reviewed by the NYCHA Administrator.
3. All labor rates will be based on either normal or overtime hourly rates plus overhead and profit. Normal working hours are from 8 AM to 4 PM; overtime hours are any hours worked outside normal working hours, weekends or holidays.
4. The vendor must be able to sub-contract to the specific equipment manufacturer regarding any special repair work that cannot be completed by the vendor. This work will be performed and invoiced using the “Allowance” line item. NYCHA owns and operates General and Caterpillar generators. A full list will be included in Appendix K.
MINOR PREVENTIVE MAINTENANCE: For each Generator, perform four (4) Minor Preventative Maintenance visits annually, once per quarter.
