Structural engineering automation for mass timber design
Web-based platform that automates structural design calculations for Cross-Laminated Timber (CLT), glulam, and timber connections. Eliminates manual spreadsheet work and provides real-time supply chain integration with timber manufacturers.
Why This Tool Exists
Structural engineers spend days manually building spreadsheets to verify mass timber calculations (CLT floor/wall/beam design, connections). Complex wood engineering calculations are error-prone and slow to iterate, delaying project delivery and preventing designers from exploring cost-effective design alternatives. Knowledge gaps in mass timber design (not covered in traditional engineering curricula) further slow adoption of sustainable timber solutions.
Web-based platform automates structural design calculations for CLT, glulam, and timber connections using Eurocode 5, AS1720, and CSA O86 standards. Turns days of manual calculations into minutes of automated analysis. Includes interactive design tools for beam/column/floor/wall/connection design with real-time supply chain integration from timber manufacturers (Sterling Structural, Mercer, Timber Unlimited) and educational resources to bridge knowledge gaps.
