Lease or purchase
It is the SPONSOR's intent to enter into an agreement with a PROPOSER for the lease or purchase of the Russell Hangar for aeronautical use. Such use may include the provision of FBO services, operation of the fuel farm, operation of an MRO facility or any combination thereof.
The County will enter into an agreement that is the most advantageous to the County, so potential respondents are encouraged to be creative with their submittals. The most favorable proposal will be one that includes the provision of FBO services, to include operation of the fuel farm and operation of an MRO facility.
Any proposal for purchase of the building will be judged based on whether or not the offer provides adequate coverage of the County's initial investment in the project. The RFP does not state a lease rate, a lease term, a purchase price, or the amount of that investment. A purchase proposal is optional.
The winning proposer has 30 days, from the date of receipt of the Notice of Award, to execute the lease and/or other documents provided by the SPONSOR. Big Horn County reserves the right to reject any and all proposals.
Source: RFP p.4, Part I Intent; p.9, Part IV; p.11, Part V Execution.
The proposer shall provide evidence of previous experience in MRO, FBO and fuel farm operations. Services shall be in accordance with the Minimum Standards in Appendix A. Appendix A, not this page, sets out what an FBO agreement requires.
