IANAL, but my understanding is that if the project is initiated and developed by an employee using company resources on "company time", then ownership of the work is automatically granted to the company, as a "work for hire". With the exception of patent rights, that is, which are nonetheless assigned to the company as a matter of course in standard employee contracts. So no special contract is needed if the creator of a project is an employee.
