The private contractor is responsible for the planning,
construction, financing, operating – and optional - the
exploitation of the real estate. Different to the owner model
there is no obligation to transfer the ownership of the
construction at the end of the contract. The contractor has
rather the option to return the construction or to take it over
for the estimated residual value that has been fixed in
advance. Besides the purchase option a lease extension
option or exploitation rights are possible. As user fee the
public body pays leasing instalments that are fixed in the
contract as well as the price for redeeming the purchase
option. Components of the instalments are fees for the
(partial-)amortisation of the costs for planning, construction
and financing as well as for the management (facility
management) incl. risk and profit mark-up.
