Dear Nanjappa,
Please tell the service provider to submit the quotation. Based on the quotation, you may prepare Purchase Order (PO). The validity of the PO could be for a year or so. The PO should include the terms and conditions on the following counts:
a) Frequency of the garbage collection
b) Precautionary measures are to be taken while collecting and loading the garbage. The service provider should arrange the tools and equipment for garbage collection on his own.
c) General code of conduct for the staff employed by the garbage collecting agency. For example, before entering the company premises, they should not chew the Gutka or betelnut leaves. They should not spit anywhere on the premises. Their movements to other than designated areas are prohibited.
d) Who will maintain the records for the collection of garbage? In what format these will be maintained? Attach the format as Appendix to the PO.
e) What will be the payment terms (i.e. after what span of time the payment will be done on submission of the invoice by the service provider)?
f) Indemnification: - The service provider should indemnify the purchaser against the damage suffered or losses incurred in the course of the collection of the garbage.
Note on point (d) above: - Your security should maintain a separate register to record the instances of garbage collection. The number of persons entering the premises and their in/out time should be recorded properly. It should tally with the invoice raised by the service provider.
Thanks,
Dinesh Divekar
