Can the new HOAI ensure planning quality?

The Fee Structure for Architects and Engineers (HOAI) is an ordinance issued by the German Federal Government to regulate the fees for architectural and engineering services in Germany. The regulation changed at the beginning of the year. Since the fees are freely negotiable

The Fee Structure for Architects and Engineers (HOAI) changed at the beginning of the year. We have summarized for you here what this means for planners and planning quality.

The Association of German Architects (BDA) disagrees. For the association, the abolition of minimum and maximum rates in the HOAI fundamentally threatens German building culture. The amendment to the HOAI has been in force since 01.01.2021 and is causing uproar among those who see their profession in danger. The BDA is convinced that the federal government has made things too easy for itself. Read about alternative proposals here.

The Fee Structure for Architects and Engineers (HOAI) changed at the beginning of the year. The Bundesrat approved the amendment so that the new law could come into force. The changes mainly affect the minimum and maximum rates of the HOAI. The fees are therefore freely negotiable. The previous price specifications are non-binding. They are for guidance only. You can find the current version of the entire HOAI regulation here.

The reason for the amendment to the HOAI was a ruling by the European Court of Justice (ECJ). In 2019, the ECJ found that the HOAI in its then current version violated the EU Services Directive. According to this directive, the provision of services may not be made dependent on fixed minimum or maximum prices. After the ruling was announced, the Federal Republic of Germany was obliged to implement it swiftly and adapt the national legal system to the requirements of the ECJ ruling.

What does the loss of binding force mean? Can the HOAI remain the basis for calculating fees? Many fear a deterioration in planning quality. The Association of German Architects (BDA), for example, sees numerous disadvantages in abandoning the minimum and maximum rates of the HOAI.

According to a statement by the BDA, this could lead to a drop in prices and the loss of jobs in Germany. As a result, the entire profession could suffer because costs would be cut. This would make it less attractive for young talent. For an industry in which there is already a noticeable shortage of staff and a lack of young talent, this would indeed be fatal.

In addition, there could be strong concentration processes among offices. This means that offices with many employees could prevail, while smaller ones might not survive. The BDA also fears that building culture will suffer if the supply situation deteriorates. The public sector and its own profession would be significantly affected by this. These conceivable scenarios for the BDA are based on the experience of other countries.

As the binding nature of price law is now no longer applicable, the contractual agreement of architectural services will become all the more important. The Committee of Associations and Chambers of Engineers and Architects for the Fee Structure (AHO) points this out. The AHO also emphasizes that the HOAI overall system has proven itself. There is nothing to prevent clients and contractors from continuing to adopt the HOAI fee bases in the future. The AHO strongly advises this in order to prevent price dumping and loss of quality.

Together with the Federal Chamber of Engineers and the Federal Chamber of Architects (BAK), however, the AHO criticizes the lack of an appropriateness clause in the new HOAI. In a press release, Dr.-Ing. Heinrich Bökamp, President of the BAK, states: “We would have liked the regulation to make it clearer that these fees must also be appropriate in the future.”

The BAK is underpinning the fact that planning contracts should continue to be based on the HOAI with a button campaign. The slogan ‘Planning is valuable’ should be passed on by the members. The aim is to raise awareness among architects and clients alike. BAK President Barbara Ettinger-Brinckmann therefore also appeals to architects and planners to stand up for the value of their work so that they are not undercut by service providers from outside the profession.

BDA: Don’t just look at the prices

Back to the BDA statement. It discusses whether the minimum HOAI rates really could not be saved or whether there were other ways of implementing the EU requirements.

A key point for the BDA is the fact that, in principle, architectural services could be provided by anyone. The association is convinced that where no proof of competence is required, there is no protection of the quality of a service. Instead of touching the price specifications, the requirements for service providers could have been formulated more specifically, according to the proposal. The authors cite membership of a chamber as an example of this.

Furthermore, architectural and engineering services could be legally defined. In the statement, this is formulated as follows: “any activity for planning in specific third-party construction matters, as soon as these require planning in individual cases.”

In conclusion, the BDA would have liked the ECJ ruling to have been implemented differently. In other words, the focus should not have been on prices, but on maintaining quality. And so it says accordingly: “Abandoning the minimum rates of the HOAI is therefore not absolutely necessary, but represents a legislative decision.” The federal government would not have made use of its creative options.

For this reason, the BDA cannot see how the federal government intends to ensure the quality of construction. Especially against the background of ecological construction with all its pressing issues or the design of urban space, the authors would have liked to see more ingenuity in the implementation of the ECJ ruling.

Voices from the profession on the ECJ HOAI

In its ruling of July 4, 2019, the European Court of Justice disapproved of the binding nature of minimum and maximum rates as an unjustified competitive disadvantage for foreign market participants. We gathered opinions from the profession at the time. Including Franz Damm, Managing Partner at Keller Damm Kollegen, Dieter Pfrommer, publicly appointed and sworn expert for fees for landscape architecture services, IHK Region Stuttgart and Jens Henningsen, bdla economics spokesperson, Treasurer.

Blockchain technology is often associated with cryptocurrencies such as Bitcoin, but has many more applications, particularly in the area of mobility. Blockchain is a decentralized database that records transactions transparently and tamper-proof. In mobility, this technology opens up new opportunities to optimize transport networks, prevent fraud and increase efficiency. Blockchain provides a secure platform for managing the data and transactions that occur daily in complex transportation systems.

Fun fact: According to a study by Deloitte, blockchain technologies in the transport sector could generate global savings of up to 30 billion US dollars by 2030.

Blockchain is based on several principles that make it particularly suitable for use in mobility.

Decentralization

Instead of a central database, information is stored in a network of nodes. This decentralization makes the system resistant to failures and manipulation.

Transparency

Every transaction is recorded in the blockchain and can be viewed by all network participants. This promotes trust and prevents fraud.

Security

Cryptographic encryption and consensus mechanisms make the blockchain virtually tamper-proof. This is particularly important for sensitive data such as ticketing information or payment details.

Smart contracts

Smart contracts are self-executing contracts that are executed automatically when certain conditions are met. They automate processes such as payments, bookings or insurance claims.

Practical example: A blockchain-based car sharing system could use smart contracts to only grant access to vehicles once payment has been confirmed.

Blockchain offers a wide range of applications that can make mobility safer, more efficient and more transparent.

Digital ticketing and payment processing

Blockchain enables a tamper-proof and transparent ticketing system for public transportation. Users can purchase their tickets digitally without having to rely on central providers.

Car sharing and ridesharing

Decentralized platforms could make carsharing and ridesharing services more efficient by enabling the booking, payment and handling of journeys directly between users.

Logistics and supply chains

In logistics, blockchain can be used to track the transportation of goods and prevent manipulation in the supply chain. Every movement of a delivery is recorded in the blockchain, which increases transparency.

Traffic management and parking systems

Blockchain can make traffic management systems more efficient by providing real-time data on traffic flows and parking options. Users could reserve and pay for parking spaces via decentralized platforms.

Practical example: a pilot project in Vienna is using blockchain to securely manage parking tickets and make the process more transparent.

The introduction of blockchain in mobility offers numerous advantages that benefit both users and operators.

Transparency and trust

Blockchain increases transparency by making all transactions publicly visible. This creates trust between users and providers and reduces fraudulent activities.

Fraud protection and security

Cryptographic encryption makes the blockchain secure against manipulation. This protects users from fraud and operators from financial losses.

Increased efficiency

Blockchain automates processes such as payments and bookings, saving time and costs. Smart contracts make it possible to minimize administrative tasks and speed up processes.

Data integrity

Data stored in the blockchain cannot be subsequently changed. This ensures that all information remains correct and trustworthy.

Expert opinion: According to a study by PwC, blockchain-based systems could reduce operating costs in the transportation sector by up to 15 %.

Despite its advantages, there are also challenges that need to be overcome when introducing blockchain in mobility.

Scalability

Blockchain technology reaches its limits with high transaction volumes. Cities with busy transportation systems need to ensure that the technology can be scaled.

Energy consumption

Blockchain systems, especially those with proof-of-work consensus mechanisms, consume significant amounts of energy. This is at odds with the sustainability goals of many cities.

Legal and regulatory issues

The introduction of blockchain in mobility requires a clear legal framework, particularly with regard to data protection, liability and contract law.

Acceptance by users and operators

The implementation of new technologies requires time and acceptance from users and operators. Transparent communication about the benefits and functionality of blockchain is crucial.

Expert opinion: According to a survey by Gartner, 40% of companies consider regulatory uncertainty to be the biggest obstacle to the introduction of blockchain.

Vienna: Blockchain for parking systems

In Vienna, blockchain is being used to digitize parking management. Users can reserve and pay for parking spaces and extend their parking times, all via a decentralized platform.

Seoul: blockchain for local public transport

In Seoul, the city is testing a blockchain-based platform for public transportation that makes ticketing and payment processing more secure and transparent.

Rotterdam: logistics with blockchain

Rotterdam is using blockchain to make logistics chains in the port more efficient. Every movement of containers is recorded in the blockchain, which increases transparency and prevents fraud.

The further development of blockchain technology will continue to revolutionize mobility in cities.

  1. Integration with IoT: IoT devices could be connected directly to the blockchain to capture and analyze traffic flows and vehicle data in real time.
  2. AI-powered analytics: AI could use blockchain data to analyze traffic flows and create predictive models for more efficient mobility
  3. Smart contracts for insurance: Insurance claims could be automated and processed faster by relying on blockchain-based smart contracts.
  4. Decentralized mobility platforms: Blockchain could serve as the basis for platforms that connect users* directly with providers* and eliminate the need for centralized intermediaries.

Future outlook: In Dubai, a blockchain system is being developed that integrates traffic management, insurance and ticketing into a single platform to make the city’s mobility more efficient and transparent.

Blockchain technology offers enormous opportunities to make mobility in cities safer, more efficient and more transparent. From digital ticketing and car sharing to logistics and traffic management – blockchain creates trust and optimizes urban processes. Despite the challenges, particularly in terms of scalability and legal issues, blockchain has the potential to fundamentally transform mobility and make cities smarter and more sustainable.

Concluding thought: Blockchain is more than just a technical trend – it is a transformative force that will shape the mobility of tomorrow. A future in which transportation systems are transparent, efficient and connected starts with blockchain technology.
