# Ground-Up Office & Mixed-Use Construction This skill provides comprehensive guidance for construction project managers working on ground-up office buildings and mixed-use developments. Coverage includes speculative office, build-to-suit, corporate headquarters, and complex mixed-use projects with retail, residential, and parking components. ## Quick Reference: Project Type Selection | Project Type | Key Characteristics | Primary Reference | |--------------|---------------------|-------------------| | Speculative Office | Unknown tenants, flexible design, market-driven | [speculative-office.md](references/speculative-office.md) | | Build-to-Suit | Single tenant, custom design, lease-driven | [build-to-suit-office.md](references/build-to-suit-office.md) | | Corporate HQ | Owner-occupied, brand-driven, amenity-rich | [corporate-headquarters.md](references/corporate-headquarters.md) | | Mixed-Use | Multiple uses, complex coordination | [mixed-use-developments.md](references/mixed-use-developments.md) | ##
