The following scope of service describes the desired requirements for Plumbing Services. The City will consider proposals that meet exact or equal scope of service. All City entities, excluding the Advertising and Promotion Commission jurisdiction (Civic Center, Mountain Tower, Visitor's Center, and Museum), will be included in this contract. Regular plumbing services should be rendered at an hourly rate as indicated in the Line Items tab. If a service call charge is applicable, the respondent shall describe in detail how and when it will be applied. Emergency and non-emergency service call rates will be considered. The City reserves the right to award the “Plumbing Service” and the “RPZ Testing” separately. To be considered for RPZ testing, the respondent shall provide an RPZ testing certification with the proposal under the response attachments. 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 emergencies. In emergency circumstances the contractor is only to stabilize the situation; further action will be at the discretion of the department director. The department will be responsible for issuing a purchase order the next workday. When a purchase order has been issued and work is complete, the contractor will send an invoice for the work performed as soon as possible 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, and a listing of materials used. It also requires a City representative's signature to approve the work. The contractor is to use only one worker (or charge for only one worker) in situations that need only one worker. The contractor shall not add any additional travel or mileage charges to the invoice. If the City requests, all replaced parts/materials must be left with the City. If asked, the contractor must be prepared to provide copies of his invoices from his materials and parts suppliers.
