Terms & Conditions

Foundations of our business relationship

Dr. Wallner Engineering GmbH (hereinafter referred to as DRWE) provides services for clients on the basis of the agreements made in the respective contracts and these General Terms and Conditions. The services offered on this website are aimed exclusively at commercial clients. The customer shall provide all services, information and material resources necessary for DRWE to perform the service at its own expense and risk. If essential services, information and materials are not provided on time, incorrectly or incompletely, DRWE is entitled to demand compensation for the damage caused by the delay after prior warning and a reasonable period of notice. DRWE is entitled to terminate the existing contract without notice if the supplies are not provided within a reasonable period of grace.

Payment

All services are remunerated in accordance with the contractually agreed fixed price or time spent. Project meetings at DRWE are generally billed on a time basis. In the case of design services, remuneration is agreed on the basis of the applicable collectively agreed or statutory provisions. In the event of changes in collectively agreed wages or allowances or other changes that have a financial impact, DRWE has the right to adjust the remuneration in accordance with the changed circumstances. The remuneration details are net in euros plus the applicable statutory value added tax, without any other deductions. Invoices shall be issued in accordance with the agreements in the respective service specifications and orders. Payments are due 14 calendar days after the invoice date. Travel costs and expenses shall be invoiced separately by DRWE. The customer shall have no right of retention against claims of DRWE. Offsetting is only permitted with claims of the customer that are recognized by DRWE or have been legally established. Translated with DeepL.com (free version)

Exceeding the agreed scope of services

The agreed-upon compensation applies exclusively to the scope of services specified in the offer, the order confirmation, or the respective service slip, in particular to the agreed-upon number of participants, users, or authorized access holders. Any increase in the agreed-upon number of participants, users, or authorized access holders requires the prior written consent of DRWE. There is no entitlement to such an increase. If the customer utilizes services beyond the agreed-upon scope of services or permits third parties to participate or use the services without a prior written agreement to that effect, DRWE is entitled to invoice for these additional services retroactively. Payment for these additional services shall be based on the prices agreed upon in the offer or the order confirmation. If no individual prices are specified therein, billing shall be calculated on a pro rata basis based on the agreed-upon compensation or according to DRWE’s price list valid at the time the services are provided. Any further statutory or contractual claims of DRWE remain unaffected by this provision.

Terms of payment

Bei Festpreisvereinbarungen sind auf den Festpreis monatliche Ab­schlags­zah­lung­en zu leisten, fällig am 01. Ka­len­der­tag eines jeden Monats, be­gin­nend mit dem 01. solchen nach Auf­trags­be­ginn. Die Höhe der monatlichen Abschlagszahlungen richtet sich nach dem von der DRWE ge­gen­ge­zeich­ne­ten Nachweis. Abweichungen davon be­dür­fen einer besonderen schrift­lich­en Vereinbarung. Bei Beginn der Auf­trags­aus­füh­rung durch die DRWE hat der Kunde Abschlagszahlungen in Hö­he eines Drittels des vereinbarten Fest­prei­ses zu leisten. Diese Ab­schlags­zah­lung wird mit den monatlich fällig wer­den­den Abschlagszahlungen ver­rech­net.

Bei der Vergütung nach vereinbarten Stundensätzen ist die DRWE be­rech­tigt, 14-tägig die erbrachten Leistungen durch Zwischenrechnungen ab­zu­rech­nen und entsprechende Ab­schlags­zah­lung­en vom Kunden zu fordern. Zwi­schen­rech­nung­en sind 14 Tage nach Erhalt auszugleichen. 

DRWE shall issue a final invoice to the customer once the order has been completed. This is due for settlement within 14 days of receipt.

Default of payment

In the event of default in payment, DRWE shall be entitled to charge interest at a rate of 9 percentage points above the applicable base interest rate (Section 247 BGB), unless lower damages are proven. DRWE reserves the right to claim higher damages caused by default. If the customer is in default of payment and a reasonable grace period set has expired without result, DRWE shall be entitled to withdraw from this service contract, to demand a lump-sum compensation amounting to 30% of the agreed order value or compensation for the proven damage caused by non-performance. If DRWE claims the lump-sum compensation, the customer reserves the right to provide evidence of lower damages.

Offsetting & right of retention

Gegen Forderungen der DRWE aus dem Dienstleistungsvertrag kann der Kunde nur mit solchen Ge­gen­for­de­rung­en auf­rech­nen, die rechtskräftig festgestellt oder unbestritten sind. Zu­rück­be­hal­tungs­rech­te können nur hin­sicht­lich solcher Gegenrechte geltend gemacht werden, die aus diesem Dienst­lei­stungs­ver­trag herrühren. 

Implementation of the work & project manager

DRWE shall appoint a responsible project manager to the customer. This project manager shall be responsible for the proper execution of the work, compliance with safety regulations and the supervision of DRWE's personnel. The organization of the work and the manner in which it is carried out is the sole responsibility of DRWE, without prejudice to the customer's right to monitor the assigned orders for their contractual execution.

Warranty for contracts for work & services

If the work is defective, the customer must give DRWE the opportunity to rectify the work. The customer may only assert the statutory warranty rights after two unsuccessful attempts at rectification.

DRWE shall only be liable to pay compensation for such defects that are directly attributable to the work, while compensation for indirect damage and compensation for consequential damage is excluded. Unless DRWE is guilty of gross negligence or intent.

Awarding of subcontractors

Die DRWE kann die Durchführung von vertraglich vereinbarten Dienst­lei­stung­en ganz oder teilweise an Un­ter­auf­trag­neh­mer vergeben. Wird ein Unterauftragnehmer mit der Ver­ar­bei­tung personenbezogener Daten be­auf­tragt, ist die vorherige Zustimmung des Auftraggebers erforderlich. 

Delay in performance

DRWE is entitled to exceed agreed delivery dates to a reasonable extent.

Liability

Die DRWE haftet bei schuldhaftem Ver­hal­ten ihrer gesetzlichen Vertreter oder bei groben Verschulden eines Un­ter­auf­trag­neh­mers für den typisch vorhersehbaren Schaden. Eine Haftung für darüberhinausgehende Fol­ge­schä­den wie z.B. ent­gang­en­er Gewinn, aus­ge­blie­be­ne Einsparungen und sonstige mittelbare Schäden sowie für auf­ge­zei­chne­te Daten ist aus­ge­schlos­sen. Eine Haftung der DRWE bei der Verletzung von Vertragspflichten, die nicht zu oben genannten Personenkreis gehören, ist im Falle der einfachen Fahrlässigkeit aus­ge­schlos­sen. Bei Ereignissen hö­he­rer Gewalt (Streik, Aussperrung oder Ähn­li­chem), die einer der Parteien die Lieferungen oder Leistungen we­sent­lich erschweren oder vorübergehend unmöglich machen, berechtigen diese die Erfüllung der Verpflichtungen um die Dauer der Behinderung und zu­sätz­lich um eine an­ge­mes­sene Anlaufzeit. Die Haftung ist der Höhe nach auf den Umfang der allgemeinen Be­triebs­haft­pflicht­ver­si­che­rung der DRWE be­schränkt (2 Mio. €), es sei denn es han­delt sich um grobe Fahrlässigkeit oder Vorsatz. Schadensersatzansprüche gegen die DRWE verjähren nach 12 Monaten ab dem Zeitpunkt der schuld­haf­ten Pflichtverletzung. 

Confidentiality

DRWE undertakes to treat as confidential all information of the customer designated as confidential that becomes known in connection with the execution of the order. Data will only be passed on to third parties with the written consent of the customer. DRWE is entitled to process the customer's data automatically within the scope of order processing. The obligation of confidentiality does not apply to ideas, concepts, know-how and techniques as well as to information that was already known to the contracting parties or becomes known to them outside the cooperation.

Retention of title & entrepreneur's lien

DRWE shall retain title to the development, planning and design documents as well as models, documentation and software supplied by it even after acceptance until the agreed remuneration has been paid in full.

DRWE is entitled to a lien on the customer's development, planning and design documents and models produced or modified due to contractual claims arising from the production of a work. The right of lien shall also exist if the items remain in the possession of the customer.

Academy

DRWE reserves the right to cancel booked or commenced events at short notice due to illness of the trainer or other disruptions in business operations for which DRWE is not responsible. Furthermore, DRWE reserves the right to cancel training courses if the minimum number of three participants is not reached. In this case, participation fees that have already been paid will be refunded in full (for events that have been booked but not yet started) or proportionately (for events that have already started). The participants concerned will be informed immediately. Further claims are excluded.

Participants have the right to nominate substitute participants to attend the event in their place if they are unable to attend in person.

Ein kostenfreier Rücktritt von Schu­lung­en ist bis 4 Wochen vor Schu­lungs­be­ginn möglich. Bei einer Stornierung bis 14 Tage vor Veranstaltungsbeginn stellen wir 50% der Teilnahmegebühr in Rechnung. Bis 5 Tage vor Ver­an­stal­tungs­be­ginn berechnen wir 75%. Er­folgt der Rücktritt ab 5 Tage vor Ver­an­stal­tungs­be­ginn oder erfolgt ein No-Show, wird die volle Teilnahmegebühr in Rechnung gestellt. Alle Stor­nie­rung­en haben per Mail an kontakt@drwe.de zu erfolgen.

Participants in open company events can transfer to other training courses up to 5 working days before the start of the course free of charge.

Die im Angebot oder in der Auf­trags­be­stä­ti­gung angegebene maximale Teil­neh­mer­zahl ist verbindlicher Be­stand­teil des Vertrages. Wird diese Teil­neh­mer­zahl überschritten, ist die DRWE berechtigt, die zusätzlichen Teilnehmer gemäß den Regelungen zur Ü­ber­schrei­tung des vereinbarten Lei­stungs­um­fangs nachträglich abzurechnen oder die Durchführung der Veranstaltung bis zur Klärung auszusetzen.

Software development, customization & installation

Die DRWE übernimmt Software Ent­wick­lungs-, Anpassungs- und/oder In­stal­la­tions­ar­bei­ten für Kunden auf Grund­­lage der in den jeweiligen Auf­trä­gen getroffenen Vereinbarungen und diesen Allgemeinen Ge­schäfts­be­ding­ung­en.

Rights of use & copyrights of work results

After full payment of the agreed remuneration, the customer shall receive a non-exclusive and non-transferable right to use the software developed by DRWE. This entitles the customer to use the software, including documentation, for the contractually stipulated purpose. All other rights of use shall remain with DRWE. Copies of the software are only permitted for data backup purposes.

Acceptance

After installation of the software by DRWE, the customer is obliged to confirm the installation in writing. The customer is obliged to check the fulfillment of the contract of the software including documentation for the essential functions and to declare its acceptance in writing. The inspection period shall be three weeks from the date of delivery, unless otherwise agreed. The software shall be deemed to have been accepted as soon as its usability is not significantly restricted due to reported defects for a period of two weeks after expiry of the inspection period. If partial deliveries have been agreed, these shall be accepted separately.

Billing of additional services

If DRWE provides services over and above the services agreed in the contract for work and services, the customer shall pay for these additional services in accordance with DRWE's applicable rates and prices.

Changes to the programming

In the event that the customer or third parties make changes to the software developed by DRWE, DRWE shall be released from any warranty obligation. Further warranty claims against DRWE are excluded, with the exception of any statutory claims based on the assurance of properties. With regard to liability for warranted characteristics, liability for consequential damage caused by defects is generally excluded, unless the warranty was intended to protect against such damage. In particular, DRWE does not guarantee that the programs meet the specific requirements of the customer or that certain results can be achieved with them. If, in the course of warranty work, it turns out that DRWE is not responsible for the error that has occurred, DRWE shall be entitled to charge the customer for the expenses incurred in accordance with DRWE's applicable rates and prices.

Publications

Statements made by one contracting party to the press about the cooperation require the prior written consent of the other contracting party. Exceptions to this are the mention of the customer in DRWE's customer lists and the general description of the subject matter of the contract in DRWE's offers or other marketing documents. The prohibition of publication also does not apply to announcements intended exclusively for internal distribution or to disclosures required by legal or accounting regulations.

Enticement of employees

Während der Wirksamkeit und für die Dauer von zwei Jahren nach Be­en­di­gung der Zusammenarbeit verpflichten sich die DRWE und der Kunde keinen derzeitigen Mitarbeitenden oder sonst vertraglich verpflichtete Personen der Ver­trags­par­tner mittelbar oder un­mit­tel­bar abzuwerben. 

Place of jurisdiction & applicable law

This contract is subject to German law. The exclusive place of jurisdiction for all disputes is Stuttgart.

Should individual provisions be invalid, this shall not affect the validity of the remaining provisions.
