Deconstruction Calculator


Based on project parameters and material inventory, the Deconstruction Calculator estimates the environmental impacts of deconstruction and traditional mechanized demolition. The calculator also estimates the full retail value of the materials suitable for reuse.

This project is a collaboration between BPS and Multnomah County.
