Need for updating the fee structure of the Ordinance on Fees for Architectural and Engineering Services (HOAI)

Introduction
The Fee Structure for Architects and Engineers (HOAI) is intended to ensure performance-based and appropriate fees for architectural and engineering services through its minimum and maximum rates. Against this background, the Federal Ministry of Economics and Technology (BMWi) commissioned the "ARGE HOAI GWT-TUD/Börgers/Kalusche/Siemon" (in short: ARGE HOAI) with the expert opinion within the framework of the research project "Need for updating the fee structure of the Ordinance on Fees for Architectural and Engineering Services (HOAI)". This was preceded by a European tendering procedure.

The expert opinion is intended to provide the legislator with a basis for the further amendment of the HOAI. For this purpose, the need for updating the fees on the basis of the service profiles proposed in the BMVBS final report is to be reviewed in actual terms. In this context, an evaluation of the last HOAI amendment of 2009, in which the table values and thus the minimum and maximum rates were raised by 10% across the board, should also be carried out. Depending on the results of the evaluation, proposals are to be made for revising the respective fee scales. The new fee scales should then be used to present the economic and financial effects on architects' and engineers' fees (contractor's perspective) and on public budgets (client's perspective) in further study steps.

The subject of the study are the results and proposals from the BMVBS final report. Reviews expressly requested in the BMVBS final report or suggested by the expert working groups will be carried out. A further basis for the investigation - especially with regard to the test parameters to be applied - is the Status Report 2000plus.
