Key takeaways
- Tenant improvements often require multiple coordinated engineering disciplines.
- Change of use, occupancy, or load can expand the review beyond the tenant space.
- Existing base-building capacity and landlord criteria should be confirmed early.
Why tenant improvement scopes grow
A project that begins as an interior layout can affect structure, egress, accessibility, ventilation, plumbing fixtures, electrical load, fire alarms, sprinklers, kitchen exhaust, grease systems, or rooftop equipment. Restaurants, medical uses, assembly spaces, and changes of occupancy often require broader coordination.
Documents to gather before engineering
- Existing approved drawings and current field survey
- Landlord design criteria and base-building information
- Proposed use, occupant load, layout, equipment, and operating requirements
- Structural modifications and equipment-support needs
- Mechanical, electrical, plumbing, fire-alarm, and sprinkler scope
- Permit-review comments and discipline-specific submission rules
Coordinate disciplines before final sealing
Ceiling congestion, roof penetrations, electrical loads, equipment weights, rated assemblies, access clearances, and control interfaces should be resolved across disciplines. A late equipment change can affect several sealed sheets and calculations.
Frequently asked questions
Do all tenant improvement drawings need a PE stamp?
Not necessarily. The required professional disciplines and sheets depend on the scope, jurisdiction, and professional-practice rules.
Can the landlord's old drawings be used as verified existing conditions?
Record drawings are useful but may not match current conditions. The design team should identify what requires field verification.
