The individual service profiles of the Fee Structure for Architects and Engineers (HOAI) are subdivided into service phases, whereby the service profiles regularly have 9 service phases.

LP1: Basic determination
LP2: Preliminary planning
LP3: Design planning
LP4: Approval planning
LP5: Implementation planning
LP6: Preparation of the award
LP7: Participation in the awarding of contracts
LP8: Project supervision - construction supervision and documentation
LP9: Property management

The service phases are the smallest units assessed by the HOAI.

The service phases in turn contain the basic services. Basic services are understood to be those services “which are generally required for the proper fulfillment of a contract” (see Section 3 (2) HOAI).

Special services are not included in the HOAI evaluation system. The HOAI does list special services. However, this list is neither complete, nor is there an assessment of the special services, the fee for which is freely agreed (see Section 3 (3) sentence 3 HOAI).
