On this page we inform you about the processing of your personal data when using our website and about your rights under data protection law.
a) Responsible body
The person responsible within the meaning of the DSGVO and other national data protection laws of the member states as well as other provisions of data protection law is the:
ZAI Ziegler and Aulbach Ingenieurgesellschaft mbH
52072 Aachen, Germany
0241 9367 1800
b) General information on data processing
1) Scope of processing of personal data
We process personal data of users in order to provide a functioning website and, if necessary, to provide further services.
The collection and use of personal data of our users only takes place after prior consent.
An exception applies in those cases in which it is not possible to obtain prior consent for actual reasons and the processing of the data is permitted by statutory provisions.
2) Legal basis
The legal basis for the processing of personal data is "lawfulness of processing" pursuant to Art. 6 DSGVO:
3) Data erasure and storage period
The personal data of the person concerned will be deleted or blocked as soon as the purpose of storage no longer applies.
In addition, the data may be stored if the European or national legislator has provided for this in EU regulations, laws or other provisions to which the person responsible is subject. The data shall also be blocked or deleted if a storage period prescribed by the aforementioned standards expires, unless it is necessary for further storage of the data for the conclusion or performance of a contract.
c) Provision of the website and creation of log files
1) Description and scope of data processing
Each time a user accesses this website, the system automatically collects the following data and information from the user's computer:
(1) The IP address of the user
The data is also stored in the log files in the system of the website operator. These data are not stored together with other personal data of the user.
2) Legal basis for data processing
The legal basis for the temporary storage of data including IP addresses and log files is Art. 6 para. 1 lit. f DSGVO.
Legitimate interests of the person responsible
- Delivery of the website
- statistical evaluations
- Improvement of the website.
3) Purpose of data processing
The temporary storage of the IP address by the system is necessary to enable delivery of the website to the user's computer. For this purpose, the IP address of the user must remain stored for the duration of the session.
The data is stored in log files to ensure the functionality of the website. The data is also used to optimise the website and to ensure the security of our information technology systems. An evaluation of the data for marketing purposes does not take place in this context.
4) Duration of storage
The data will be deleted as soon as they are no longer required for the purpose for which they were collected.
In the case of the collection of data for the purpose of providing the website, this is the case when the relevant session has ended, i.e. the data is deleted immediately after the end of the relevant session.
If IP addresses are stored in log files, the above text must be supplemented as follows:
If the data is stored in log files, this is the case after seven days at the latest.
A storage going beyond this is possible. In this case, the IP addresses of the users are deleted or alienated so that it is no longer possible to assign the calling client.
5) Objection and removal option
The collection of data for the provision of the website and the storage of data in log files is mandatory for the operation of the website.
Consequently, there is no possibility of objection on the part of the user.
1) Description and scope of data processing
When a user visits a website, a cookie can be stored on the user's operating system. This cookie contains a characteristic string of characters that enables the browser to be uniquely identified when the website is called up again.
Many cookies contain a unique identifier, the so-called cookie ID. This cookie ID enables visited web pages and servers to be assigned to the Internet browser used for this purpose in which the cookie was stored. This enables the visited websites to distinguish the Internet browser of the person concerned from other Internet browsers which also contain other cookies. In this way, a certain Internet browser and thus possibly a data subject can be recognised and identified.
2) Legal basis for data processing
The legal basis for the processing of personal data using cookies is Art. 6 para. 1 lit. a DSGVO if the user has given his consent.
3) Purpose of data processing
The user data collected by technically necessary cookies are not used to create user profiles.
The analysis cookies are used for the purpose of improving the quality of our website and its contents.
The analysis cookies tell us how the website is used and enable us to optimise the website.
Our legitimate interest in the processing of personal data pursuant to Art. 6 para. 1 lit. f DSGVO also lies in these purposes.
4) Duration of storage, objection and removal options
The person concerned can prevent the storage of cookies at any time by adjusting the settings of the Internet browser used and thus permanently object to the storage of cookies. Cookies that have already been saved can be deleted at any time. This is possible in all common Internet browsers. Deactivation of cookies by the person concerned may mean that not all functions of our website can be used in full.
e) Contact form and e-mail contact
1. Description and scope of data processing
A contact form is available on our website, which can be used for electronic contact. If a user takes this opportunity, the data entered in the input mask will be transmitted to us and stored. These data are e.g:
(2) First name, surname,
(4) Telephone number,
(5) Email address,
At the time the message is sent, the following data will also be stored:
(1) Date and time of the request
(2) Name entered in the contact form
Alternatively, you can contact us via the e-mail address provided. In this case, the personal data of the user transmitted with the e-mail will be stored.
In this context, it does not pursue the passing on of data to third parties. The data will be used exclusively for the processing of the conversation.
2. Legal basis for data processing
The legal basis for the processing of the data is Art. 6 para. 1 lit. a DSGVO if the user has given his consent.
The legal basis for the processing of data transmitted by e-mail is Art. 6 para. 1 lit. f DSGVO. If the purpose of the e-mail contact is to conclude a contract, the additional legal basis for the processing is Art. 6 para. 1 lit. b DSGVO.
3. Purpose of data processing
The processing of the personal data from the input mask serves exclusively for the treatment of the establishment of contact. In the case of contact by email, this also constitutes the necessary legitimate interest in the processing of the data.
The other personal data processed during the sending process serve to prevent misuse of the contact form and to guarantee the security of our information technology systems. This is also the necessary legitimate interest in the processing of the data processed during the sending process.
4. Duration of storage
The data will be deleted as soon as they are no longer necessary to achieve the purpose for which they were collected. For the personal data from the input mask of the contact form and those sent by email, this is the case when the respective conversation with the user has ended. The conversation is terminated when it can be inferred from the circumstances that the relevant facts have been conclusively clarified.
The additional personal data collected during the sending process will be deleted after a period of seven days at the latest.
5. Possibility of objection and removal
The user has the possibility to revoke his consent to the processing of personal data at any time.
If the user contacts us via email, he can object to the storage of his personal data at any time via email. In such a case, the conversation cannot be continued.
In addition, it is possible to send the objection by telephone, letter or contact form.
All personal data stored in the course of establishing contact will be deleted in the event of an objection.
f) Rights of the data subject
If personal data are processed by a data subject, he has the following rights vis-à-vis the person responsible:
1. Tight to information Art. 15 DSGVO Right to information of the data subject
The data subject shall have the right to obtain from the controller confirmation as to whether personal data relating to him or her are being processed; if this is the case, he or she shall have the right of access to such personal data and to the following information:
(1) the purposes for which the personal data are processed;
(2) the categories of personal data processed;
(3) the recipients or categories of recipients to whom the personal data relating to you have been or will be disclosed;
(4) the planned duration of the retention of the personal data relating to you or, if it is not possible to provide specific information in this regard, criteria for determining the retention period;
(5) the existence of a right to rectify or delete personal data concerning you, a right to limit the processing by the controller or a right to object to such processing;
(6) the existence of a right of appeal to a supervisory authority;
(7) all available information on the origin of the data, if the personal data are not collected from the data subject;
(8) the existence of automated decision-making including profiling in accordance with Art. 22 (1) and (4) DSGVO and - at least in these cases - meaningful information on the logic involved and the scope and intended effects of such processing on the data subject.
You have the right to request information as to whether the personal data concerning you will be transferred to a third country or to an international organisation. In this context, you may request to be informed of the appropriate guarantees pursuant to Art. 46 DSGVO in connection with the transfer.
2. Art. 16 DSGVO Right to rectification
You have the right to have your personal data corrected or completed by the data controller if the personal data processed concerning you is inaccurate or incomplete. The data controller must carry out the rectification immediately.
3. Art. 18 DSGVO Right to limitation of processing
Under the following conditions, you may request that the processing of your personal data be restricted:
(1) if you dispute the accuracy of the personal data concerning you for a period of time which allows the controller to verify the accuracy of the personal data;
(2) the processing is unlawful and you refuse to erase the personal data and instead request that the use of the personal data be restricted;
(3) the controller no longer needs the personal data for the purposes of the processing, but you need them for the assertion, exercise or defence of legal claims, or
(4) if you have objected to the processing pursuant to Art. 21 para. 1 DSGVO and it has not yet been established whether the legitimate reasons of the data controller outweigh your reasons.
If the processing of personal data concerning you has been restricted, such data - apart from their storage - may only be processed with your consent or for the assertion, exercise or defence of legal claims or for the protection of the rights of another natural or legal person or for reasons of an important public interest of the Union or a Member State.
If the processing restriction has been limited in accordance with the above conditions, you will be informed by the controller before the restriction is lifted.
4. Art. 17 DSGVO Right to deletion ("right to be forgotten")
The data subject shall have the right to obtain from the controller the erasure without delay of personal data relating to him or her and the controller shall be obliged to erase without delay personal data for any of the following reasons:
Personal data relating to you shall no longer be necessary for the purposes for which they were collected or otherwise processed.
(2) You revoke your consent on which the processing pursuant to Art. 6 para. 1 lit. a or Art. 9 para. 2 lit. a DSGVO was based and there is no other legal basis for the processing.
(3) You object to the processing pursuant to Art. 21 para. 1 DSGVO and there are no overriding legitimate reasons for the processing or you object to the processing pursuant to Art. 21 para. 2 DSGVO.
(4) The personal data concerning you have been processed unlawfully.
(5) The deletion of your personal data is necessary to fulfil a legal obligation under Union law or the law of the Member States to which the controller is subject.
(6) The personal data relating to you have been collected in relation to information society services offered pursuant to Article 8(1) DSGVO.
If the data controller has made the personal data concerning you public and is obliged to delete them pursuant to Art. 17 para. 1 DSGVO, he shall take appropriate measures, including technical measures, taking into account the available technology and the implementation costs, to inform the data controllers processing the personal data that you, as the data subject, have requested them to delete all links to this personal data or copies or replications of this personal data.
The right to deletion does not exist insofar as processing is necessary:
(1) to exercise the right to freedom of expression and information;
(2) to fulfil a legal obligation which the processing entails under the law of the Union or of the Member States to which the controller is subject or to carry out a task carried out in the public interest or in the exercise of official authority vested in the controller;
(3) for reasons of public interest in the field of public health pursuant to Art. 9 para. 2 lit. h and i as well as Art. 9 para. 3 DSGVO;
(4) for archive purposes in the public interest, scientific or historical research purposes or for statistical purposes in accordance with Art. 89 para. 1 DSGVO, insofar as the law referred to under a) is likely to make it impossible or seriously impair the attainment of the objectives of such processing, or
(5) to assert, exercise or defend legal claims.
5. Art. 19 DSGVO Notification obligation in connection with the correction or deletion of personal data or the restriction of processing
If you have exercised your right to rectify, cancel or limit the processing of your personal data against the controller, the latter is obliged to notify all recipients to whom the personal data concerning you have been disclosed of such rectification, cancellation or limitation, unless this proves impossible or involves a disproportionate effort.
You have the right to be informed of such recipients by the data controller.
6. Art. 20 DSGVO Right to data transferability
You have the right to receive the personal data concerning you that you have provided to the responsible person in a structured, common and machine-readable format. In addition, you have the right to communicate these data to another data controller without being hindered by the controller to whom the personal data was provided, provided that
(1) the processing is based on a consent pursuant to Art. 6 para. 1 lit. a DSGVO or Art. 9 para. 2 lit. a DSGVO or on a contract pursuant to Art. 6 para. 1 lit. b DSGVO and
(2) the processing is carried out by automated means.
In exercising this right, you also have the right to request that the personal data concerning you be transferred directly from one responsible person to another responsible person, insofar as this is technically feasible. Freedoms and rights of other persons must not be affected by this.
The right to data transfer does not apply to the processing of personal data necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.
7. Art. 21 DSGVO Right of objection
You have the right, for reasons arising from your particular situation, to object at any time to the processing of your personal data on the basis of Art. 6 para. 1 lit. e or f DSGVO; this also applies to profiling based on these provisions.
The person responsible will no longer process the personal data concerning you unless he can prove compelling grounds for processing worthy of protection which outweigh your interests, rights and freedoms, or the processing serves to assert, exercise or defend legal claims.
If the personal data concerning you are processed for the purpose of direct marketing, you have the right to object at any time to the processing of the personal data concerning you for the purpose of such advertising; this also applies to profiling insofar as it is connected with such direct marketing.
If you object to processing for direct marketing purposes, the personal data concerning you will no longer be processed for such purposes.
You have the possibility to exercise your right of objection through automated procedures using technical specifications in connection with the use of Information Society services, notwithstanding Directive 2002/58/EC.
You have the right to revoke your data protection consent at any time. The revocation of your consent does not affect the lawfulness of the processing carried out on the basis of your consent until you revoke it.
8. Art. 22 DSGVO Automated decisions in individual cases including profiling
You have the right not to be subject to any decision based solely on automated processing, including profiling, that has any legal effect on you or similarly significantly affects you. This does not apply if the decision
(1) is necessary for the conclusion or performance of a contract between you and the person responsible,
(2) is authorised by legislation of the Union or of the Member States to which the person responsible is subject and contains appropriate measures to safeguard your rights and freedoms and your legitimate interests; or
(3) with your express consent.
However, these decisions may not be based on special categories of personal data pursuant to Art. 9 para. 1 DSGVO unless Art. 9 para. 2 lit. a or g applies and appropriate measures have been taken to protect the rights and freedoms as well as your legitimate interests.
With regard to the cases mentioned in (1) and (3), the person responsible shall take appropriate measures to protect the rights and freedoms as well as your legitimate interests, including at least the right to obtain the intervention of a third party.
9. Right to appeal to a supervisory authority
Without prejudice to any other administrative or judicial remedy, you shall have the right to complain to a supervisory authority, in particular in the Member State of your residence, place of work or place of presumed infringement, if you consider that the processing of your personal data is in breach of the DSGVO.
The supervisory authority with which the complaint was lodged shall inform the complainant of the status and outcome of the complaint, including the possibility of a judicial remedy under Article 78 DSGVO.
