About CLB Engineering

CLB Engineering Corporation is the creator and maintainer of ras2cng, ras-commander, and hms-commander. CLB pioneered the LLM Forward approach to civil engineering -- a framework where licensed professional engineers leverage Large Language Models to dramatically accelerate hydraulic & hydrologic (H&H) modeling workflows while maintaining full professional responsibility and public safety standards.

What We've Built

Within two years, CLB Engineering built the most robust and feature-complete HEC-RAS and HEC-HMS automation solution on the open internet using LLM Forward approaches:

  • ras2cng: CLI tool for exporting HEC-RAS results to GeoParquet, PMTiles, and PostGIS
  • ras-commander: 50+ modules covering HEC-RAS automation
  • hms-commander: Comprehensive library for HEC-HMS automation
  • 50+ example notebooks: Production-quality demonstrations

LLM Forward Engineering

The LLM Forward philosophy is CLB's framework for responsible AI adoption in professional engineering:

Principle Description
Professional Responsibility First Public safety, ethics, and licensure remain paramount
LLMs Forward (Not First) Technology accelerates engineering insight without replacing professional judgment
Multi-Level Verifiability GUI review + visual outputs (plots/figures) + code audit trails
Human-in-the-Loop Licensed professionals in responsible charge at all times
Open Source Free and open-source tools that benefit the entire H&H community
