Terms and Conditions

About these terms

These Terms and Conditions govern the use of the website at tectumdrafting.com and the CAD drafting services offered by Sebastian Cerna Shintani ("I," "me," or "my"). By using this website or engaging my services, you agree to these terms.

Nature of services

I provide CAD drafting services only. All deliverables are drafting documents — not engineering calculations, structural engineering, architectural design services, or professional engineering work. Where local regulations require a licensed Professional Engineer's stamp, that is the client's responsibility to arrange separately.

Deliverables are provided as PDF files. DWG source files are available at an additional charge.

Scope and revisions

Each project scope is agreed in writing (via email or message) before work begins. Standard deliverables include two (2) rounds of revisions based on the agreed scope. Revisions that fall outside the original scope, or additional rounds beyond two, are billed separately.

Client responsibilities

You are responsible for:

• Providing accurate and complete information, dimensions, and reference documents
• Verifying that the delivered drawings meet your local building department's requirements before submission
• Obtaining any required engineering stamps, zoning approvals, or permits
• Any consequences arising from inaccurate information you provide

Payment

Payment terms are agreed per project. I typically require a deposit before work begins, with the balance due upon delivery. Late payments may result in work being paused. I reserve the right to withhold deliverables until payment is received in full.

Intellectual property

Upon receipt of full payment, you receive a non-exclusive license to use the delivered drawings for the specific project described in the project agreement. I retain the right to include the work in my portfolio unless otherwise agreed in writing.

I retain ownership of any reusable details, blocks, or standard templates used in the work.

Limitation of liability

My liability for any claim arising from the services provided is limited to the amount paid for the specific project to which the claim relates. I am not liable for any indirect, consequential, or incidental damages, including lost profits, project delays, or permit rejections.

These drawings are prepared based on the information you provide. I am not responsible for errors resulting from inaccurate, incomplete, or changed information.

No warranty

Deliverables are provided "as is." While I take care to produce accurate, permit-oriented drawing sets, I do not warrant that drawings will be accepted without revision by any particular building department, as requirements vary by jurisdiction and change over time.

Governing law

These terms are governed by the laws of the Republic of Peru, where I am based, without regard to conflict-of-law provisions. For U.S. clients, any disputes will be resolved through good-faith negotiation before any formal process is initiated.

Changes to these terms

I may update these terms from time to time. The "Last updated" date reflects the most recent revision. Continued engagement with my services after an update constitutes acceptance of the revised terms.
