civils.ai

What It Is

Civils.ai is a Construction AI platform launched by a Singapore-based company, primarily aimed at construction contractors, civil/foundation estimators, geotechnical engineers, and pre-construction teams. It is not a general-purpose chatbot; instead, it focuses on quantity takeoff, data extraction, and document review around PDF drawings, geotechnical reports, specifications, contracts, and standards. The official website says it has served 200+ contractors and consultants and supported more than USD 3 billion in projects.

Core Capabilities and Outputs

The platform’s core strength is measuring areas, lengths, volumes, and quantities from PDF drawings based on natural-language scope prompts, covering use cases such as foundations, landscaping, utilities, drainage, and concrete. For geotechnical teams, it can extract 16+ categories of data groups from scanned, handwritten, or digital borehole logs, export to AGS 4.1 and Excel, and generate 2D/3D site models. On the document side, it supports AI search and checking across drawings, specifications, contracts, and standards, with common checks savable as templates. Outputs can be downloaded as Excel files and annotated PDFs, with an emphasis on traceable sources.

Pricing and Integrations

Starter costs USD 90/month and includes 10 takeoffs, 1 user, and 2GB of storage. Professional costs USD 270/month and includes 30 takeoffs, 50GB of storage, revision requests, and priority support. Enterprise is custom-priced and supports unlimited users, API, MCP, SSO/SAML, custom DPA, and security reviews. Standard AI search and checks are unlimited under fair use, but complex multi-step Agents may be charged separately. Payments support major credit/debit cards, while enterprise customers can pay by bank transfer or invoice.

Pros, Cons, and Limitations

Its strengths are its strong industry focus: it can read drawings, measure, annotate, and export structured files. For modern PDF takeoff, the claimed accuracy is above 97%, and each output goes through human QA, reducing the risk of pure AI hallucination. Its data privacy statements are also relatively clear: customers retain ownership, data is not used to train models, transmission uses TLS, and servers are located in the United States. The limitations are also explicit: accuracy is not guaranteed for old drawings or hand-drawn plans; most workflows target completion within 24 hours, so it is not an instant tool; and the terms state that it is suitable only for bidding and early-stage planning, not as a replacement for review by professional engineers or detailed construction design.

Who It’s For and Access from China

It is suitable for contractors, consultants, and pre-construction teams dealing with large volumes of PDF drawings, geotechnical reports, and bidding documents, especially for estimating earthworks, foundations, landscaping, roads, and drainage. The official website does not specify whether it offers a Chinese interface, supports Chinese standards, or is accessible from mainland China, so china_access can only be considered unknown. Since data is stored in the United States, Chinese SOEs, central state-owned enterprises, or sensitive projects will need additional assessment around compliance, cross-border data transfer, and payment processes. If alternatives are needed, tools such as Togal.AI, Kreo, Autodesk Takeoff, Bluebeam, and PlanSwift are worth comparing.
