There will be no formal bid opening.

Billing: The City of Ceres shall pay only for services based on the hourly rate for work

performed on site. Invoices shall be issued to the City every month for work performed

the previous month, along with materials invoicing. At the time of the invoice, backup

documentation of the work performed by the day shall be provided.

Proposals will be evaluated on content and the understanding of the Scope of Services.

Once the staff determines the most responsive proposal to the Scope of Services, the

vendor will be contacted to begin drafting the contract terms and conditions.

The number of hours worked and the work vary from year to year. Any information that

the City cannot provide and that is necessary to properly perform the Scope of Services

is the contractor's responsibility to obtain and/or develop.

The Vendor shall perform the general and specific tasks as described in the Scope of

Services Work section of this RFP. The City shall evaluate proposals and award based

on the most responsive proposal that provides proper assurances that it can perform

these services within the specified time efficiently and professionally. Pricing will be

considered as part of the overall proposal.

requirements of this RFP. The Contractor’s proposal should emphasize a clear

understanding of the project and the necessary resources to perform the intended

services. Responsiveness to the RFP will be the principal basis for evaluation. Included

City, along with their years of service for integration and electrical services.

percentage. This value shall be used upon receipt of an invoice. A factory invoice shall
