The City will issue a purchase order as needed for each item of work. The contractor should not perform work without a City purchase order, except when called after hours or in obvious emergencies. In emergency circumstances the contractor is only to stabilize the situation; further action will be at the discretion of the department director. The involved department will be responsible for getting a purchase order issued the next work day.When a purchase order has been issued and work is complete, the contractor is to send an invoice for the work performed as soon as possible in order to receive payment. The City pays only on invoices. The contractor’s invoice shall have an attached work order showing a description of the work completed, the individual who did the work, the time spent on the job, a listing of materials used, and also requires the signature of a City representative approving the work. The contractor is to use only one worker (or charge for only one worker) in situations that need only one worker. If the City requests, all replaced parts/materials must be left with the City. The contractor must be prepared, if asked, to provide copies of his invoices from his materials and parts suppliers. The contract resulting from this RFP will be for one (1) year with four (4) 12-month extensions available upon mutual consent of both parties and approved budget by the City of Hot Springs.
