Silver Touch Technologies Limited has been awarded a significant order by RITES Limited, a Navratna Central Public Sector Enterprise under the Ministry of Railways, for the Design, Development, and Implementation of PARAKH - an AI-Based Detailed Project Report (DPR) Appraisal & Intelligence Platform.

The platform represents India's first self-hosted, multi-model AI platform for infrastructure project appraisal and will be used to appraise India's largest infrastructure projects including railways, highways, bridges, ports, airports, metro, and tunnels within India's ₹111 lakh crore infrastructure sector.

Technical Specifications

The AI-native platform includes:

  • Three self-hosted Large Language Models: Llama 3.1 70B, Mistral 7B, and Qwen 2.5 7B deployed on NVIDIA A100 GPU infrastructure within RITES' secure data center
  • Zero external data egress policy
  • 500+ codified engineering validation rules drawn from IRC, RDSO, IS, and MORTH standards
  • Hybrid Retrieval-Augmented Generation (RAG) combining semantic vector search with keyword search across 1,000+ historical DPRs
  • Four-layer hallucination prevention framework
  • Document intelligence pipeline processing DPRs of 500 to 5,000 pages with OCR, table extraction, and engineering entity recognition
  • GIS integration with PM GatiShakti National Master Plan, BIM/IFC interoperability, and geospatial analytics
  • Multi-sector knowledge graph across eight infrastructure domains
  • Enterprise-grade security with Keycloak IAM, AES-256 encryption, mTLS service mesh, and OWASP Top 10 + LLM-specific security compliance

The company transitions from an IT services company to an AI-native platform company with a production-grade AI platform capability in the infrastructure sector.

The platform creates a domain moat through proprietary 500+ codified engineering rules, sector-specific ontologies, and historical DPR knowledge base that deepens with every DPR processed.
