RAG & Knowledge Retrieval for Construction & Infrastructure

What changes when it is construction & infrastructure

Your documents do not arrive as clean markdown. They are scanned PDFs, merged cells, ten-year-old templates. The ingestion pipeline is most of the work, and we build it for the corpus you actually have.

In construction & infrastructure, sites are dispersed, connectivity is poor, and documentation lags reality by weeks. That single fact reshapes how rag & knowledge retrieval has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is drawing and RFI document handling, usually integrated against ERP. We start from the constraint, not the capability, what the system must never do, who signs off, and what happens when it is wrong.

Deployed across regulated and unregulated sectors, with audit trails where the regulator expects them. You own the code, the models where they are open-weight, and the documentation to run it without us.

progress tracking from site imagery

RAG & Knowledge Retrieval workloads in construction & infrastructure

  • progress tracking from site imagery
  • safety and PPE compliance monitoring
  • drawing and RFI document handling
  • quantity take-off support
  • subcontractor invoice validation

What is included

  • Ingestion pipeline for your real document formats
  • Chunking and embedding strategy tuned to your corpus
  • Hybrid keyword plus vector retrieval with reranking
  • Citations on every answer, traceable to the source page
  • Permission-aware retrieval that respects existing access rules
  • Retrieval quality benchmarked against a labelled question set

Questions from this sector

Can it track progress from photos?

Yes, progress estimation from site imagery against the plan, which is substantially faster and more consistent than manual reporting.

Does it work without site internet?

Yes, capture offline and sync later. Poor connectivity is the norm on sites and the system is designed around it.

RAG or fine-tuning?

RAG for knowledge that changes and must be cited; fine-tuning for style, format and task behaviour. Most production systems use RAG for the facts and light fine-tuning or few-shot prompting for the form.

How accurate will it be?

We build a labelled question set from your domain and report retrieval precision and answer accuracy against it. That number is the deliverable. We do not ship a system whose quality nobody has measured.

Can it respect our existing permissions?

Yes. Retrieval is filtered by the user's actual entitlements, so the assistant can never surface a document the user could not already open.

RAG & Knowledge Retrieval for construction & infrastructure, worth a conversation?

Tell us the workload and the regulation it sits under. We will tell you what is realistic.
