About CLB Engineering

CLB Engineering Corporation is the creator and maintainer of the hms-commander and ras-commander open-source libraries. 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:

  • hms-commander: Comprehensive library for HEC-HMS automation -- basin models, meteorologic models, execution, DSS results, Atlas 14 storms, and more
  • ras-commander: 50+ modules covering plan execution, HDF results extraction, geometry parsing, USGS integration, precipitation analysis, remote distributed execution, quality assurance, and more
  • Comprehensive agentic infrastructure: AI agents, skills, rules, and cognitive memory systems that enable engineers to work alongside AI assistants on complex modeling tasks
  • 50+ example notebooks: Production-quality demonstrations covering every major HEC-RAS and HEC-HMS workflow

This demonstrates the extraordinary value that licensed professional engineers can create when working alongside Large Language Models with clear principles and accountability.

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 HEC-HMS 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
