Silver Touch Technologies Limited has been awarded a significant order by RITES Limited to build India's first AI-based Detailed Project Report (DPR) Appraisal & Intelligence Platform, named PARAKH. The order covers the design, development, and implementation of the fully self-hosted, multi-model AI platform for a Government of India Navratna enterprise. This initiative targets India's ₹111 lakh crore infrastructure sector, spanning railways, highways, bridges, ports, airports, metro, and tunnels.

The project entails architecting a ground-up AI-native system rather than a conventional software application with AI features. The platform incorporates 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 centre, ensuring zero external data egress. Additionally, the system includes 500+ Codified Engineering Validation Rules derived from IRC, RDSO, IS, and MORTH standards to deliver deterministic, auditable checks.

Technical Specifications and Security

The platform utilises a Hybrid Retrieval-Augmented Generation (RAG) combining semantic vector search with keyword search across 1,000+ historical DPRs. A Four-Layer Hallucination Prevention Framework ensures that every AI-generated insight is citation-mandatory, source-verified, confidence-scored, and human-approved. The Document Intelligence Pipeline is capable of processing DPRs ranging from 500 to 5,000 pages using OCR, table extraction, and engineering entity recognition.

Integration features include GIS interoperability with the PM GatiShakti National Master Plan, BIM/IFC compatibility, and a Multi-Sector Knowledge Graph linking engineering parameters across eight infrastructure domains. The system adheres to OWASP Top 10 and LLM-specific security compliance standards.

Strategic Significance

Minesh V Doshi, Executive Director of Silver Touch Technologies Limited, stated that the partnership underscores the company's ability to engineer production-grade AI systems for mission-critical national applications. He highlighted that the platform's self-hosted nature and zero external data dependency are critical for maintaining security and sovereignty. The deployment creates a proprietary domain intelligence moat that deepens with every DPR processed by the system.

The order was secured through the Government e-Marketplace (GeM) portal following a competitive Quality and Cost-Based Selection (QCBS) evaluation. RITES Limited, a Navratna and Schedule 'A' Central Public Sector Enterprise under the Ministry of Railways, provides comprehensive consultancy services across transport infrastructure.
