Agreement To These Terms

These Terms of Service form a binding agreement between you and DAO AIRSPACE LTD. By accessing this website, submitting an enquiry or instructing the company to provide services, you confirm that you accept these terms and that you agree to comply with them. If you do not accept these terms, you should not use this website or engage the company.

Where services are provided under a separate written contract, that contract takes precedence over these terms to the extent of any conflict. These terms continue to apply to the use of the website and to any matter not covered by the separate contract.

You confirm that you have the authority to accept these terms on behalf of any organisation you represent. If you do not have that authority, you must not accept these terms or instruct the company on behalf of that organisation.

The company may update these terms from time to time as described in the section on changes. The version in force at the time of your use or instruction is the version that applies to that use or instruction.

Scope Of Services

DAO AIRSPACE LTD provides professional services in the field of computer systems design and related technical services. The core service lines are integrated systems design, control software engineering, cloud architecture, data integration pipelines, security architecture and technical support services. Each engagement is defined by a proposal or statement of work that describes the objectives, the deliverables, the assumptions and the boundaries of the work.

Work that is not described in the agreed scope is not included in the engagement. Additional work may be requested and, if accepted by the company, will be handled through a change request that records the effect on fees, schedule and any other relevant term. The company will not carry out chargeable work outside the agreed scope without written confirmation from the client.

The company delivers services with reasonable skill and care and in accordance with the standards generally expected of a competent professional practice in its field. The company does not guarantee a particular commercial outcome, because outcomes often depend on factors outside its control, including decisions made by the client and conditions in the wider environment.

Where the services involve access to a client system, the client remains responsible for that system and for the lawful basis on which the company is granted access. The company will use such access only for the purposes of the engagement.

Client Responsibilities

The success of an engagement depends on cooperation between the company and the client. The client agrees to provide accurate information, timely decisions and reasonable access to the people, systems and premises needed to carry out the work.

  • Provide a named contact who has authority to make decisions about the engagement.
  • Supply relevant documentation, access and test environments within agreed timescales.
  • Review and respond to requests for approval, feedback or clarification without undue delay.
  • Ensure that any third party whose cooperation is required is made aware of the engagement.
  • Comply with all laws and regulations that apply to the client and to the systems involved.
  • Obtain any consents or licences needed for the company to perform the work.

Where a delay or additional cost arises because the client has not met these responsibilities, the company may adjust the schedule or the fees to reflect the effect of the delay. The company will explain the reason for any such adjustment and will discuss reasonable alternatives before applying it.

The client is responsible for the accuracy of data and instructions it supplies and for the consequences of decisions it makes on the basis of the services. The company provides professional advice, but the client retains responsibility for its own operations.

Proposals And Acceptance

The company issues proposals that describe the proposed work, the deliverables, the assumptions, the fees and the expected schedule. A proposal is valid for the period stated in it and may be withdrawn or revised before acceptance.

A contract is formed when the client accepts a proposal in writing or otherwise instructs the company to begin work. The company may ask for a written acceptance before starting, particularly where the work involves access to sensitive systems or a significant commitment of resources.

Estimates and indicative schedules are provided in good faith and are based on the information available at the time. They are not guarantees, and they may change if the assumptions on which they rest prove incorrect. Where a material change becomes apparent, the company will raise it promptly and propose a route forward.

Any terms proposed by the client that conflict with these terms or with the company proposal apply only if the company accepts them in writing. Silence is not acceptance of a conflicting term.

Fees And Payment

Fees for services are set out in the relevant proposal or statement of work. Unless stated otherwise, fees are exclusive of applicable taxes, which are added where the law requires them. The company may charge for expenses that are reasonably incurred in delivering the work, provided those expenses are described in the proposal or agreed in advance.

Invoices are payable within the period stated on the invoice. Where no period is stated, payment is due within thirty days of the invoice date. The company reserves the right to charge interest on overdue amounts at the rate permitted by law and to recover reasonable costs of collection.

Where an engagement is delivered in stages, the company may invoice at each stage milestone. Amounts already invoiced for work properly performed remain payable even if the engagement ends before all stages are completed, unless the contract provides otherwise.

If the client disputes an invoice, it should notify the company promptly and pay the undisputed portion. The parties will work in good faith to resolve the dispute without delaying the undisputed amount.

Delivery And Timelines

The company plans delivery against the schedule agreed with the client and reports progress at agreed intervals. Timelines depend on the availability of client resources, on the responsiveness of third parties and on the accuracy of the assumptions recorded in the proposal.

Where the company becomes aware of a risk to a milestone, it will inform the client as soon as practicable and propose options. The company prefers to raise concerns early, while there is still room to adjust, rather than to report a delay after the fact.

Acceptance of deliverables is handled through the review process described in the engagement documents. Unless the client raises specific and substantiated issues within the agreed review period, the deliverables are treated as accepted. Where issues are raised, the company will address them in line with the agreed scope and will agree a sensible path for anything beyond it.

Intellectual Property

Each party retains ownership of the intellectual property it brings to an engagement. Background materials, generic tools, methods and know how created or owned by the company before or independently of the engagement remain the property of the company and may be used in other work, provided that client confidential information is not disclosed.

Upon full payment of the fees for a deliverable, the company assigns to the client the rights in bespoke deliverables that were created specifically for the client under the engagement, except for background materials and third party components embedded within them. The client grants the company a licence to use such deliverables as needed to provide support and to perform the engagement.

Where a deliverable includes third party or open source components, those components remain subject to their own licences. The company will identify material third party components and their licences so that the client can comply with the relevant obligations.

Nothing in these terms transfers ownership of trade marks, brand names or other identifiers of either party. Each party may refer to the other in general terms as a client or supplier unless the other party asks it not to do so.

Confidentiality

Each party may receive confidential information from the other in the course of the engagement. Both parties agree to use such information only for the purposes of the engagement and to protect it with at least the same care they apply to their own confidential information.

Confidential information may be disclosed to employees, contractors and professional advisers who need it to perform the work, provided those individuals are bound by duties of confidentiality at least as protective as those in these terms. It may also be disclosed where required by law or by a regulator, in which case the disclosing party will, where lawful, notify the other before making the disclosure.

Confidentiality obligations do not apply to information that is already public, that becomes public without a breach of these terms, that was lawfully known before disclosure, or that is independently developed without use of confidential information.

These obligations continue after the engagement ends. When confidential information is no longer needed, it should be returned or securely destroyed, subject to any legal or operational requirement to retain it.

Acceptable Use Of The Website

This website is provided for information and for legitimate business enquiries. You agree to use it lawfully and not to interfere with its operation or with the security of the systems that support it.

  • Do not attempt to gain unauthorised access to any part of the website or its supporting infrastructure.
  • Do not introduce malicious code, conduct denial of service attacks or probe the website for vulnerabilities without written permission.
  • Do not scrape, harvest or redistribute content from the website for commercial purposes without permission.
  • Do not submit unlawful, misleading, abusive or infringing material through any form or communication channel.
  • Do not impersonate another person or misrepresent your affiliation with any organisation.

The company may suspend or block access to the website where it reasonably believes these rules have been broken. The company also reserved the right to report suspected criminal activity to the relevant authorities.

The website is provided on an as available basis. The company does not promise that it will always be accessible or free from faults, though it works to keep it reliable and secure.

Third Party Materials

This website and the services may include references to, links to or components from third parties. Such materials are provided for convenience and information. The company does not control them and does not accept responsibility for their content, availability or practices.

Where the company uses a third party component in a deliverable, it does so under the terms of the relevant licence. The client is responsible for complying with the terms of any third party licence that applies to its use of the deliverable, particularly where the component requires attribution or imposes conditions on redistribution.

Links from this website to an external resource do not imply endorsement of that resource or of the organisation behind it. If you decide to rely on a third party resource, you do so at your own discretion and subject to the terms of that third party.

Warranties And Disclaimers

The company warrants that it will provide the services with reasonable skill and care and in a manner consistent with good professional practice. This is the principal warranty given by the company in relation to the services.

Except as expressly stated in these terms or in a separate contract, the company disclaims all other warranties, whether express or implied, to the fullest extent permitted by law. This includes implied warranties of merchantability, fitness for a particular purpose and non infringement.

The content of this website is provided for general information. It does not constitute professional advice for a specific situation and should not be relied on as such. Advice relevant to your circumstances is available through a properly scoped engagement with the company.

Nothing in these terms excludes or limits any warranty or right that cannot lawfully be excluded or limited. Where a statutory right applies, it continues to apply notwithstanding anything to the contrary in these terms.

Limitation Of Liability

Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded or limited.

Subject to the paragraph above, the company is not liable for loss of profit, loss of revenue, loss of anticipated savings, loss of goodwill, loss of data or any indirect or consequential loss arising out of or in connection with the services or the website, whether in contract, tort, misrepresentation or otherwise.

To the extent permitted by law, the total aggregate liability of the company arising out of or in connection with an engagement is limited to the fees paid by the client to the company under that engagement in the twelve months preceding the event that gave rise to the claim.

These limitations reflect the allocation of risk between the parties and the fees charged for the services. Where the law does not allow a particular limitation to apply, that limitation is severed and the remaining provisions continue in force.

Indemnity

The client agrees to indemnify and hold harmless the company against claims, losses, damages and reasonable costs arising from the client content, the client systems or the client instructions that the company is asked to act upon, except to the extent that the claim results from the negligence or wilful misconduct of the company.

The company agrees to indemnify and hold harmless the client against claims that the bespoke deliverables created specifically for the client infringe the intellectual property rights of a third party, provided the client notifies the company promptly and allows the company to control the response to the claim.

Where an indemnity applies, the party seeking it must provide reasonable cooperation and must not settle the claim without the consent of the indemnifying party. The indemnifying party may assume the defence of the claim with competent counsel of its choosing.

Termination

Either party may terminate an engagement by giving written notice in accordance with the terms of the relevant contract. Where no notice period is agreed, a reasonable period is required so that work in progress can be brought to a safe stopping point.

The company may suspend or terminate services immediately where the client fails to pay amounts due, where the client requests work that would be unlawful, or where continuing the engagement would place the company or its staff at risk.

On termination, the client pays for work properly performed up to the date of termination and for any non cancellable commitments reasonably made in support of the engagement. The company returns or makes available client materials and confidential information in line with the section on confidentiality.

Provisions that by their nature should survive termination, including those on intellectual property, confidentiality, liability, indemnity and governing law, continue to apply after the engagement ends.

Force Majeure

Neither party is liable for a failure or delay in performing its obligations to the extent that the failure or delay is caused by an event beyond its reasonable control. Such events include natural disasters, severe weather, war, civil unrest, industrial action, failure of public utilities or telecommunications, epidemic or pandemic, and acts of government.

The affected party must notify the other as soon as reasonably practicable and must take reasonable steps to mitigate the impact of the event. Obligations are suspended for the duration of the event, and the parties will discuss how to resume performance once the event has passed.

If a force majeure event continues for an extended period, either party may terminate the affected engagement by written notice without liability for the unperformed portion, without prejudice to rights that have already accrued.

Governing Law And Disputes

These terms are governed by the laws of England and Wales. The parties submit to the exclusive jurisdiction of the courts of England and Wales in relation to any dispute arising out of or in connection with these terms, except where the law gives a mandatory right to bring proceedings elsewhere.

Before starting proceedings, the parties agree to attempt to resolve any dispute through good faith discussion between senior representatives. If discussion does not resolve the matter within a reasonable period, the parties may consider mediation before resorting to litigation.

Nothing in this section prevents either party from seeking urgent relief from a court where that is necessary to protect its rights or property. The existence of a dispute does not excuse either party from continuing to perform obligations that are not in dispute.

Changes To These Terms

The company may update these terms from time to time to reflect changes in the services, in the law or in the way the company operates. The updated version is published on this page with a revised date at the top.

Where a change materially affects an existing engagement, the company will give reasonable notice and will discuss the effect with the client. Changes do not apply retroactively to work already performed under a separate contract.

Continued use of the website after a change indicates acceptance of the revised terms for the purposes of that use. If you do not accept a change, you should stop using the website and discuss any affected engagement with the company.
