1. Scope and Purpose

This application (the "App") is provided exclusively as a professional tool for supporting and assisting with engineering calculations, simulations, estimations, documentation, and data visualization related to engineering projects, including, but not limited to, HVAC systems, cleanrooms, GMP facilities, laboratories, hospitals, data centers, and other technically complex or regulated environments.

The App does not replace professional engineering judgment, engineering services performed by licensed professionals, regulatory approvals, or independent technical verification.

2. Professional Use Only

The App is intended solely for use by qualified professionals, including licensed engineers, engineering consultants, designers, and other individuals with appropriate technical education, training, and experience.

By accessing or using the App, the User represents and warrants that they:

  • are a competent professional in the relevant technical field;

  • understand the limitations of automated calculations, assumptions, and engineering models; and

  • accept full professional responsibility for all decisions, designs, and actions based on the results generated by the App.

3. Informational Nature of the Results

All calculations, simulations, reports, estimates, charts, tables, and any other outputs generated by the App:

  • are based solely on the information provided by the User;

  • rely on engineering assumptions, simplifications, approximations, and generalized models; and

  • are provided exclusively for informational and decision-support purposes.

The results do not constitute, and shall not be interpreted as:

  • professional engineering advice;

  • signed, sealed, certified, or otherwise officially approved engineering documents;

  • final construction documents, construction-ready designs, or as-built documentation;

  • regulatory approvals, certifications, or validations; or

  • legally binding or contractual documents.

4. Mandatory Independent Professional Review

All outputs generated by the App must be independently reviewed, verified, and validated by a licensed professional engineer or other legally authorized specialist, in accordance with all applicable laws, regulations, codes, and professional standards, before being used for any real-world purpose, including but not limited to:

  • engineering design or detailed engineering;

  • permit applications or submissions to regulatory authorities;

  • construction or installation;

  • commissioning, qualification, or validation;

  • audits, inspections, or compliance activities; or

  • operational or investment decisions.

Any use of the App's outputs without such independent professional review shall be entirely at the User's own risk.

5. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND.

  • loss of profits, revenue, business, data, or use;

  • project delays, cost overruns, or rework;

  • regulatory fines, penalties, or sanctions;

  • design, construction, commissioning, or operational failures; or

  • any damages arising out of or relating to the use, misuse, or inability to use the App or any of its outputs, even if advised of the possibility of such damages.

  • the User's use or misuse of the App;

  • reliance upon or application of any outputs generated by the App;

  • violations of applicable laws, regulations, or professional standards; or

  • claims brought by clients, contractors, regulatory authorities, or other third parties in connection with the User's professional work.
