SELECTED CAPABILITY PORTFOLIO
Different sectors. One controlled digital workflow.
These portfolio examples demonstrate the types of construction information NAT Survey AI can model. BESS is one example only — the service is designed for general civil engineering, infrastructure, utilities, industrial, commercial and residential construction.

UNIVERSAL BY DESIGN
Don't see your project type?
If a design contains coordinates, dimensions, levels, gradients, sections, alignments or surfaces, there is a good chance we can turn it into useful construction information.
SHOW US THE PROJECT →PAYMENTS & PROJECT COMMERCIALS
Simple, secure ways to pay.
Project work is scoped and quoted before payment. For bespoke engineering services, payment details and milestones should be agreed in the quotation or invoice.
Debit / Credit Card
Secure card checkout can be enabled for fixed-price services and digital products.
PayPal
PayPal checkout/payment links can be connected once the business payment account and final products/prices are configured.
Google Pay
Can be offered through a compatible checkout integration where eligible.
Project Invoice
Recommended for bespoke modelling: agreed scope, price, milestones and payment terms.
Payment buttons are intentionally not live yet. Do not enter card or wallet details on this page. Checkout will only be activated after the merchant account, prices, terms and test transaction are configured.
FREQUENTLY ASKED QUESTIONS
Clear answers before a project starts.
What information can I send?
PDF drawings, DWG/DXF, LandXML/XML, survey CSV/TXT, coordinates, levels, sections, alignments, sketches and a written brief.
What types of projects can you model?
Roads, earthworks, excavations, embankments, pipework, ducting, drainage, utilities, foundations, structures, platforms, survey/as-built information and custom civil-engineering requirements.
What can I receive?
Depending on scope: DXF, XML/LandXML, TIN/DTM surfaces, 3D lines, setting-out data, CSV/TXT schedules, model views and PDF/QA reports.
Can you prepare machine-control information?
Yes, where the approved source information and required target format are suitable. The intended machine/control workflow should be confirmed before export.
Is BESS your only sector?
No. Cellarhead BESS is an example showing a complex multi-discipline workflow. NAT Survey AI is designed for general civil engineering and construction modelling.
How do you handle missing or unclear information?
We identify assumptions and missing information during review rather than silently inventing engineering levels, dimensions or design intent.
Can confidential drawings be uploaded?
Use an agreed secure transfer method for confidential project files. The public enquiry form should be used for project details, not sensitive attachments.
How is a project priced?
After reviewing scope, source information, deliverables, revisions and deadline, a quotation can be prepared. Bespoke work is not treated as an instant fixed-price product unless explicitly offered that way.
