Terms and Conditions

These terms apply to contracts between TOO Steyer Engineering, Taraz, Republic of Kazakhstan, and businesses. They cover engineering, project support, and software. They are not written for consumers.

A contract is formed when we accept an order in writing, including by email, or when we start the work after the client has asked us to start. The website describes the services. Sending the enquiry form does not accept an offer, and it does not by itself create a contract.

The individual contract and the written offer prevail over these terms. These terms fill what the individual contract leaves open.

The languages of these terms are German, English, Russian, and Chinese. If a wording differs, the language of the individual contract prevails. If the contract names no language, the German text prevails.

Status: 30 September 2026.

The service is the one named in the order. The range we offer is the following.

Engineering at the plant or over a secure remote connection: troubleshooting, installation, commissioning, and maintenance of controls, PLCs, and equipment. Travel is for the work that needs a person on site. The rest can be done remotely when the client provides the connection.

CAD and design. Simulation, a digital twin, and virtual commissioning of a cell or a line before the hardware runs.

Project management and commissioning: schedule, budget, coordination with suppliers, test, calibration, safety checks against the standards that apply, and handover with the records, to the extent the order includes those items.

Building automation: building management, HVAC, controls, and energy, including links over BACnet, Modbus, or KNX where the order names them.

Software for engineering teams: web applications, portals, dashboards, shops, ERP, CRM, quality management aligned to ISO 9001, CAD viewers for STEP, JT, and GLTF, desktop applications, and links between systems. The client receives the source, the documents, and a build when the individual contract says so.

The industries are automotive, including OEM and tier-1 plants, rail, aerospace, industrial manufacturing, and building automation. The work is done under a quality system certified to ISO 9001:2015.

We owe the agreed work. We do not owe the commercial result of a line or of a piece of software. We are not the general contractor for a plant unless the individual contract says that in those words. Our engineers work as our staff on our service. Supply of temporary workers is part of the contract only if the individual contract says so expressly.

We may use subcontractors. We remain responsible toward the client for their work.

Before the work starts, the client states the systems, the dates, and the limits. The client gives access to the plant, to documents, to a contact person, and, where agreed, to the remote connection. Site rules and safety instructions of the client apply to our people on site.

Decisions, approvals, and test data have to arrive in time for the agreed date. If the work waits for the client, the dates move by the waiting time. Extra cost caused by late cooperation is not ours, unless we caused the delay.

The client remains responsible for running the plant, for safety on the client's premises, and for having a legal basis to hand us personal data and third-party drawings.

Duties, dates, and results are fixed in writing before the start. A change of scope applies when both sides confirm it in writing, including by email. Price and dates are adjusted with that confirmation.

A defined result, such as a software release, a document set, or a commissioning record, is accepted when the client accepts it, or when ten business days pass after handover without a written list of concrete defects and the client uses the result. Defects that do not stop use do not block acceptance. We correct them within a reasonable time. Hidden defects are notified when the client knows them.

We perform the work with the care of an engineering firm. For slight negligence, liability is limited to the foreseeable damage typical of this kind of contract, and to the fee of the order concerned, where mandatory law allows that limit.

We are not liable for lost profit, production stoppage, or other consequential loss, where mandatory law allows that exclusion. The limits do not apply to intent, to gross negligence, to injury to life, body, or health, or where the law forbids a limit.

Dates move, and liability is limited to what we are answerable for, in cases of force majeure, of a change the client requests, of missing cooperation, and of a failure by a third party we did not choose.

Visible defects are notified in writing without undue delay. The time limit for a claim follows the individual contract and the mandatory law. A claim is not lost merely because fourteen days have passed.

The text of the website is not a warranty of a particular plant result.

Fees, day rates, or a fixed price are agreed before the work starts. Travel, accommodation, and other expenses are charged when the offer names them, or when the visit requires them and the client has agreed.

Invoices are due within the agreed period, otherwise within 14 calendar days of the invoice date. Currency and taxes are those stated on the invoice.

If payment is late, we may pause the work until the overdue amount is paid. Interest on late payment follows the law that applies. Pausing the work moves the dates by the length of the pause.

Tools, libraries, and methods that existed before the order stay with us or with the person who holds the rights. The client receives the right to use them as far as the delivered work needs that use.

For results made under the order, the client receives the right of use required for the agreed purpose. A transfer of the rights, or delivery of source code, is what the individual contract states. Where that contract promises the source, the documents, and a build, the client receives them.

Drawings, models, and data the client provides stay with the client. We use them only for the order.

Third-party components, including CAD kernels and payment functions inside a shop we build, stay under the licence of that third party. We do not pass on a wider right than that licence gives.

Each side keeps non-public information of the other side confidential during the contract and after it ends, for as long as the information is not public, not already known, and not lawfully received from someone else.

Disclosure is allowed to staff and to subcontractors who need the information for the work and who are bound to confidentiality, and where the law requires disclosure.

Personal data in the project are handled as described in the privacy notice. If we operate or maintain a system in which the client processes personal data, we conclude a processing agreement where the law requires one. The client remains responsible for the lawfulness of the data the client puts into that system.

These terms and the contract are governed by the law of the Republic of Kazakhstan. The courts in Taraz have jurisdiction. Mandatory rules at the place of a service remain in force where they cannot be waived.

The parties will try to settle a dispute by a written notice and a reply before filing a claim. That attempt does not block a deadline or an injunction.

If a clause is invalid, the remaining clauses stay in effect. The invalid clause is replaced by a valid one that comes as close as possible to the economic purpose.

These terms are the general basis. They do not replace the individual contract. Changes and side agreements are effective when they are in writing, including by email.

A right is not waived because we do not exercise it at once.
