Open Source Construction Management Software
Construction management is a thin space for open source: the field is dominated by heavyweight proprietary suites, and most teams in practice stitch together project, document, and scheduling tools rather than find a single open replacement. The few open source options here cover the project-management and document-tracking core - tasks, drawings, RFIs, and daily logs - on infrastructure you host, which is often enough to anchor a workflow you fill in around.
