About InfraLens

Civil engineering reference,
built by an engineer.

InfraLens is an independent initiative making Indian Standard (IS) codes, IRC codes, NBC, engineering calculators, 550 ready templates (PMC · QA/QC · Site Formats), and the CPHEEO Manuals free and searchable for every civil engineer in India — no paywall, no signup, no ads.

Why we exist

Building the data + AI layer for Indian infrastructure

Indian infrastructure is at an inflection point. The National Infrastructure Pipeline projects ₹143 lakh crore of investment through 2025, NHAI is adding 10,000+ km of highways every year, 100 smart cities are operationalising, and by 2050 another 416 million people will be added to Indian cities. Every one of those projects — highways, metros, water grids, housing, InvIT-owned assets — is being designed, built, and operated by engineers, consultants, and PMC teams using workflows that haven't fundamentally changed in two decades.

Civil and infrastructure engineering has the deepest data of any engineering discipline — IS codes, IRC standards, MoRTH specs, CPHEEO manuals, DPR archives, BOQ tenders, site QA/QC records, hydrology timeseries, InvIT financials, geotechnical reports, concrete mix designs. Almost none of it is structured. Almost none of it is queryable. Critical design decisions — route alignment, foundation type, water-supply sizing, seismic detailing, procurement specification — are still made by professionals digging through eight scattered sources to cross-check one clause, while the institutional knowledge of senior engineers leaves with them when they retire.

InfraLens is building the data + AI layer that fixes this. The direction is a SaaS stack of AI-assisted tools for engineers, consultants, and project owners — covering code reference, design automation, DPR structuring, cost & asset intelligence, QA/QC workflow, risk scoring, and project analytics. Tooling that collapses the "find the right clause → run the calc → document the decision" loop from hours to seconds, and that preserves the tacit knowledge inside every Indian engineering practice in a form future engineers can actually query.

What you see on the site today — searchable IS / IRC / CPHEEO codes, the handbook, free design calculators, QA/QC templates, PMC templates, GATE prep — is the foundation layer. It structures the data spine, earns trust, and proves the thesis that Indian engineering standards can be systematised rather than scattered. The AI-driven decision-support layer sits on top of this, and is what we're actively building toward.

We don't sell IS codes. We don't replace BIS. We're building the decision-support stack Indian infrastructure has always needed — and giving away the reference layer, free, to get there.

Services offered

Specialised consulting at the intersection of Infrastructure, Data & AI

Beyond the free reference layer, InfraLens takes on paid consulting engagements for organisations building tooling, data products, or decision systems for the Indian infrastructure sector. Engagements typically fall under three practice areas — and are often combined:

🏗️
Domain consulting
Infrastructure & EPC
  • Bidding strategy
  • Organisation automation
  • Optimisation of workflows
  • DPR & project-report automation
…and other bespoke engagements
🗂️
Data engineering
Structured engineering data
  • IS / IRC / MoRTH / CPHEEO data pipelines
  • Engineering knowledge graphs
  • Cost, BOQ & rate-analysis databases
  • Scraping, validation & enrichment systems
  • Research-grade structured datasets
🤖
AI & ML
Intelligence on top of the data
  • LLM-powered code search & clause Q&A
  • Design-automation prototypes (RCC, hydraulics, etc.)
  • Document intelligence — DPR / BOQ / tender parsing
  • Predictive analytics on project & asset data
  • AI-assisted engineering assistants

Who built this

SA
Sourabh Agarwal
Founder · Infrastructure Analyst

I work at the intersection of infrastructure engineering, capital markets, and data-driven decision systems.

With a background in civil engineering and project execution, I have evolved into a deep-dive infrastructure analyst — decoding EPC companies, InvITs, urban development models, and large-scale public infrastructure programs across India.

Through Infra Lens, I simplify complex engineering and policy frameworks into structured, research-backed insights.

Work through InfraLens
  • Highway & EPC sector analysis
  • InvIT & infrastructure asset valuation
  • Smart city & riverfront development models
  • Water grid & large-scale utility planning
  • DPR structuring & feasibility documentation
Also at StockLens — systematic investment frameworks
  • Earnings transcript & rating-report analysis on listed Indian companies
  • Multi-factor simulation models (technical, fundamental, sentiment)
  • Backtesting of 20+ quant strategies
  • Python automation + HFT simulations
  • Research-grade structured financial databases
Currently exploring
  • Textile manufacturing (Surat-based rapier & water-jet loom setup)
  • Woven geotextile plant development (bank-ready DPR structuring)
  • AI-assisted civil engineering handbook applications
  • Quant-driven capital allocation systems

Data & methodology

How the data is built

  • Bureau of Indian Standards (BIS) published code listings as the primary spine.
  • Archive.org and law.resource.org for free PDF availability — 86 % of codes have direct links, the rest fall back to Google search.
  • Automated enrichment (LLM-assisted) extracts key tables, clauses, values, and FAQs from each code.
  • Manual verification of the highest-traffic codes (IS 456, IS 800, IS 1893, IS 875, IS 10262, IS 13920).
  • Quarterly health-check audits of external PDF links — broken URLs are detected and either re-sourced or removed.

Always refer to the original IS code document for design and compliance decisions. InfraLens is not affiliated with the Bureau of Indian Standards.
