Solicitation / RFP / RFQ

This document is a "Determination to Solicit From a Single Source" for a brand-name requirement. The Bureau of Reclamation, Grand Coulee Power Office requires 9,000 gallons of Exxon-Mobil DTE Heavy-Medium Oil Group I with ISO Grade 68. This will be a firm-fixed-price contract with an estimated cost and a delivery date of 30 days after receipt of order.

• 9,000 gallons of Exxon-Mobil DTE Heavy-Medium Oil Group I with ISO Grade 68.

• The oil must be compatible with the existing system, which uses Mobile DTE Heavy Medium ISO turbine oil (a Group I type oil). Mixing Group I and Group II oils is prohibited due to solvency differences and proprietary additives, which could lead to excessive air entrainment, gumming of governor filters and valves, and voiding warranties.

• Contract Type: Firm-fixed-price.

• Period of Performance: Delivery within 30 days after receipt of order.

• Estimated Cost: Stated as "estimated at [redacted] with".

• Prices will be determined fair and reasonable through competitive quotes received in response to a solicitation for the specified brand-name product.

• Not specified in this document.

• This determination is for a single source because only Exxon-Mobil's oil meets the specific requirements to avoid system incompatibility and warranty issues.

• Market research included searching GSA, UNICOR, AbilityOne, and issuing a sources sought. Nine vendors responded, but only two proposed a suitable Group I oil (Mobil Heavy Medium DTE).
