Open-source engineering calculators for civil and structural design
Structural, geotechnical, tunnelling and contractor tools available free and open source on GitHub.
Searchable construction datasets covering high-rise buildings, bridges, tunnels, dams and housing.
Registered users get calculation workings, bending/shear/deflection diagrams and PDF export.
Four project-based pathways in Python, AI for construction, AI governance and building AI agents.
Web search API and crawler built for AI agents
Run natural-language or keyword queries against a large independent web index with filters for domain, date and category.
Return cleaned page text and AI-extracted highlights so agents receive the most relevant excerpts instead of entire pages.
