Vern,
We're going to go with Far 13, Services for demoliion work and a small part landscaping. We want to solicit for bid options for work that can be done when funding becomes available. We do not want to provide contract financing. We will not pay for percentage complete. A lot of people get confused about this since this has a "construction" feel that we would pay percentage complete on the demolition and landscaping work. Since this project will take months to do we might break up the work into jobs, such as separting the buildings to be demo'd and pay per building as the contract progresses.
I guess the original question was can we use bid options that are in construction contracting for services contracts. It was just because I have never used bid options in service contracts except for extending the period of performance. Far 17.2 Options actually says that subpart does not apply to contracts for "(a) services involving the construction, alteration, or repair (including dredging, excavating, and painting) of buildings, bridges, roads, or other kinds of real property;" But it reads below "However, it does not preclude the use of options in those contracts."
I did not see that part until later so it appears you can use bid options for services that involve construction.
