AI Search Over Specs, RFIs and Drawings for Engineering Firms: What Works and What to Check First

Engineering firms sit on decades of specifications, RFIs, submittals, calculations and drawings that nobody can search well. Retrieval with a model on Bedrock makes them answerable, with citations. What it is good at, the licensing and client-data questions to settle first, and why the engineer of record stays responsible.

The most valuable early AI system in an engineering firm is usually not design automation. It is search: "how did we detail this connection on the last three hospital projects?", "what did the owner answer on RFI 214?", "which projects used this spec section?". Retrieval-augmented generation over the firm's own documents answers those questions with links to the source.

What it does well

  • Finding precedent across past projects: details, specification language, calculation approaches.

  • Answering questions from RFIs, submittals and meeting minutes, with the document and page cited.

  • Reading title blocks and drawing lists to index drawing sets by project, discipline and revision.

  • First drafts of routine documents from the firm's own templates and past examples.

Question

Why

Can we index purchased standards and codes?

Many standards are licensed per user with restrictions on copying; check each publisher's licence before loading them into any system

Do client contracts allow it?

Some contracts restrict how project data is used or where it is stored

Which projects are export-controlled or CUI?

Those documents must stay in an environment approved for them, such as AWS GovCloud, or out of the system

Who can see what?

Search results must respect project permissions, or the system leaks one client's documents to another team

How we would build it

  1. Start with one document type and one question people ask weekly, such as RFIs.

  2. Index with permissions attached to every chunk, filtered at query time by the user's project access.

  3. Require citations in every answer, and show the source page next to it.

  4. Build an evaluation set of 50 to 100 real questions with known answers and rerun it on every change.
