1. Formation of the Agreement

An agreement is formed when the client accepts a written quotation, confirms a booking in writing, or instructs work to begin. LEADSENS TECHNOLOGIES LIMITED will not begin chargeable work until the scope has been confirmed in writing, so that both parties share the same understanding of what is to be done.

Where a client places a purchase order, the terms of that order apply only to the extent that they do not conflict with these terms. Any variation must be agreed in writing by a person authorised to act for the company. These terms supersede prior discussions about the same subject unless a later signed contract expressly replaces them.

2. Definitions

The company means LEADSENS TECHNOLOGIES LIMITED. The client means the person or organisation that commissions the services. The alignment room means the premises at Rm 532B 5/F STAR HSE, 3 SALISBURY RD, Tsim Sha Tsui, Hong Kong (HK). The services means the six service lines described on this website and any related work agreed in writing. A chart means a drift record, dot run or alignment report we produce. A retainer means a recurring arrangement for scheduled calibration visits.

References to writing include email, because in practice most instructions are given that way. References to a working day mean a day on which banks in Hong Kong are open for normal business. The singular includes the plural where the context allows, and headings are for convenience only and do not affect the meaning of a clause.

3. Scope of Services

The company provides alignment services performed from a fixed reference. Plumb-line surveys compare built elements against a vertical line. Sensor mount alignment sets and confirms the mounting of instruments. Drift monitoring records movement over an agreed window. Mount fabrication produces brackets and cradles on the bench. Settlement watches track structural change across the calendar. Retainer calibration provides scheduled returns to the room.

The services are limited to what a hung line, a datum plate and a clipped sensor can honestly establish. They are not structural engineering, not a warranty of building safety, and not a substitute for advice from a qualified structural engineer where such advice is required. If a reading suggests a safety concern, the company will say so promptly, but the duty to obtain specialist structural advice rests with the client or the building owner.

4. Quotations and Estimates

Quotations are prepared from the information available at the time. Where the site turns out to differ materially from what was described, the company may adjust the scope and the fee and will explain the reason in writing before proceeding. A quotation is valid for the period stated on it, and where no period is stated it is valid for thirty days.

An estimate is a considered view rather than a fixed price, and it may change with the actual work encountered. The company will not exceed an estimate by a material amount without first seeking the client approval, except where urgent work is needed to prevent damage or harm, in which case the company will proceed with the minimum necessary and report immediately.

5. Booking and Scheduling

Bookings are confirmed when a date is agreed in writing. The company will state the expected duration and the personnel involved. Site visits depend on access being available, and the company may need to reschedule where access is refused, delayed or unsafe.

Retainer holders receive priority on scheduled dates and on the winter alignment slots. Where demand exceeds capacity, the company will allocate dates fairly among confirmed bookings and will give as much notice as possible of any change. The company will not cancel a confirmed booking without good reason and will offer an alternative date where it does.

6. Site Access and Client Duties

The client will provide safe and timely access to the elements to be aligned, together with any permits, escorts or approvals that the building requires. The client will tell the company about known hazards, live services, fragile materials, restricted areas and any rule that affects how the site may be used.

The client is responsible for the accuracy of the information it supplies and for protecting the work area while the company is present. Where the client arranges a third party, such as a lift operator or a security team, the client will ensure that the third party cooperates with the visit. The company may stop work and leave the site where conditions are unsafe, and any resulting delay is treated as a client-caused delay.

7. Reference and Datum Data

The company maintains a high line and a datum plate in the alignment room and re-checks them each season. The reference used for a client job will be recorded on the chart. Where a client has an existing reference held by another party, the company can adopt it only after verifying it, and any difference will be reported.

Reference data belongs to the company as part of its working method, but the client receives the measurements and charts that relate to the client own premises. The company will not disclose a client reference to a third party without permission, except as required by law or as needed to deliver the agreed work.

8. Charts and Reports

Every job ends with a dated chart filed on the rail and a copy sent to the client. The chart records the dot run, the shape of the movement, and a plain-language interpretation. It notes any element outside the agreed tolerance and recommends a course of action where one is clear.

Charts are a record of conditions at the time of measurement. They are not a prediction and not a guarantee that a building will remain within tolerance. Where a client relies on a chart for a decision with significant consequences, the company encourages the client to commission a fresh check so that the record reflects current conditions.

9. Mount Fabrication Terms

Mounts are fabricated to the drawings and dimensions agreed in writing. Once a mount has been cut and drilled to a client-supplied dimension, it is treated as bespoke and may not be returnable. The client is responsible for checking that the supplied dimensions suit the intended structure.

The company warrants that a mount will be free from defects in material and workmanship at the time of delivery and will hold the geometry recorded on its bench chart. The warranty does not cover damage from misuse, from installation by others contrary to the supplied instructions, or from exposure beyond the conditions for which the mount was specified.

10. Retainer Calibration Terms

A retainer provides a defined number of calibration visits over a stated period, together with priority scheduling and a running file of charts. Retainer fees are invoiced in advance for the period unless the parties agree otherwise.

A retainer does not oblige the company to carry out work outside the agreed scope, and unused visits do not automatically roll into a later period. The company will remind a retainer holder when a visit falls due and will make reasonable efforts to schedule it. A retainer may be renewed on the terms current at the time of renewal.

11. Fees and Payment

Fees are stated in the quotation and exclude any tax that the law requires the company to add. Invoices are payable within the period stated on the invoice, and where no period is stated payment is due within thirty days of the invoice date.

The company may charge reasonable travel and access costs where these were not included in the quotation, and will obtain approval before incurring a significant cost of that kind. Late payment may attract interest at the rate permitted by law, and the company may suspend further work on an overdue account after giving written notice. The client remains liable for all sums due for work already performed.

12. Cancellation and Rescheduling

A client may reschedule a booked visit at no charge with reasonable notice, which the company normally treats as two working days. Cancellation with less notice may attract a fee that reflects the lost bench and travel time, and the company will state that fee in advance where it applies.

Where a visit is cancelled because of unsafe conditions, the company will not charge a cancellation fee and the parties will agree a new date. Where the company must cancel for its own reasons, it will offer the earliest available alternative and will not charge for the cancelled visit.

13. Warranty and Re-Checks

The company warrants that its services will be performed with reasonable skill and care and in accordance with the method described on this website. If a client believes that a service fell short of that standard, the client should notify the company promptly and give the company an opportunity to re-check the work.

Where a re-check shows that the company measurement or alignment was at fault, the company will correct the work at no additional charge. The warranty does not extend to movement caused by later structural change, by third party work, or by events outside the company control, and it does not convert a technical measurement into a structural guarantee.

14. Limitation of Liability

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for any liability that the law does not allow to be limited. Subject to that, the company liability for a claim arising from a service is limited to the fee paid for the service in question.

The company is not liable for indirect or consequential loss, for loss of profit, for loss of business opportunity, or for the cost of third party remedial work, except where such loss is a direct and foreseeable result of a failure by the company. The company will not be liable for a decision taken by the client in reliance on a chart where the client did not seek a fresh check as recommended.

15. Insurance

The company maintains public liability and professional indemnity cover appropriate to its work. A certificate of insurance is available on request. Where a client requires a specific level of cover or a named endorsement for a project, the company will discuss the requirement before the booking is confirmed.

The client is responsible for insuring its own property and for any plant or materials it provides. The company will report any damage it causes promptly and will cooperate with the client insurer in the resolution of a claim.

16. Intellectual Property

The company retains ownership of its methods, drawings, chart formats, reference data and website content. The client receives a licence to use the charts and reports supplied for the purposes of the project for which they were produced.

The client may not resell, publish or redistribute a company chart as if it were its own work, and may not present a chart out of context in a way that misleads a third party. Where a client wishes to share a chart with a contractor or authority, the company will generally agree and will supply a copy on request.

17. Confidentiality

Each party will keep the other confidential information private and will use it only for the agreed purpose. Confidential information includes drawings, schedules, pricing, access codes and any material marked as private. The obligation does not apply to information that is already public, that is independently developed, or that must be disclosed by law.

The company keeps client records in a locked cabinet and in a secure electronic store, and limits access to team members who need it for the work. The duty of confidence continues after an engagement ends, for as long as the information retains value to the party that supplied it.

18. Data and Privacy

Personal information is handled in accordance with the company privacy policy, which forms part of these terms. The policy explains what is collected, why it is used, how long it is kept and how a person can exercise their rights. A copy is available on this website and on request from engineering@leadsens.lat.

Where the company processes personal information on behalf of a client, it will follow the client documented instructions and will not use the information for any other purpose. The company will assist the client in responding to a request from an individual, to the extent that the law requires.

19. Force Majeure

Neither party is liable for a failure to perform caused by an event beyond its reasonable control. Such events include severe weather, typhoon signals, epidemic restrictions, utility failure, civil disturbance and government action. The affected party will notify the other promptly and will resume performance as soon as it can.

Where a force majeure event continues for a prolonged period, either party may terminate the affected engagement by written notice. Fees for work already performed remain payable, and the company will return any deposit that relates to work it can no longer deliver.

20. Termination

Either party may terminate an engagement by written notice where the other party commits a material breach and does not remedy it within a reasonable period after being asked to do so. The company may terminate immediately where continuing would be unsafe or unlawful, or where a client becomes insolvent.

On termination, the client will pay for work performed up to the date of termination, and the company will deliver the charts and reports produced to that date. Clauses that by their nature should survive termination, including confidentiality, intellectual property and limitation of liability, continue to apply.

21. Governing Law and Disputes

These terms are governed by the laws of Hong Kong. The parties will first attempt to resolve any dispute through good faith discussion, and the company will always take a call to talk a problem through before resorting to formal steps. Where discussion does not resolve the matter, the dispute will be submitted to the exclusive jurisdiction of the courts of Hong Kong.

If any clause of these terms is found to be invalid or unenforceable, the remaining clauses continue in full force. A failure to enforce a clause on one occasion does not waive the right to enforce it on another. These terms, together with the relevant quotation and the privacy policy, form the entire agreement between the parties.
