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.

Adjacent Uses	Required Separation	Key Considerations	Primary Reference
Office/Retail	1-hour (sprinklered)	Separate entries, MEP	occupancy-separation-requirements.md
Office/Residential	2-hour	Acoustic, separate cores	occupancy-separation-requirements.md
Office/Parking	2-hour	Ventilation, egress	occupancy-separation-requirements.md

Quick Reference: High-Rise Code Triggers

Requirement	Trigger Height	Code Reference	Primary Reference
High-Rise Package	75' occupied floor	IBC 403	high-rise-code-requirements.md
Sprinkler Required	75' (sooner in many uses)	IBC 903.2	high-rise-code-requirements.md
