While tenant improvement work may often be completed without professional involvement, assembly occupancies may require professional involvement for reasons of complexity, occupant load or required equipment. 

NBC-AE Division C 2.4.3. Schedules of Professional Involvement 

When required by NBC-AE Division C 2.4.2. or deemed necessary by the Authority Having Jurisdiction, schedules of Professional Involvement shall be provided for all applicable professions involved in the project.

Notes: 

Assembly occupancies that typically require professional involvement in their design and submission of drawings include ones that:

• Occupy over 300 sq. m. in project area.
• Require the reclassification of the whole building (even if NOT over 300 sq. m.).
• Propose the construction of a mezzanine, addition or another storey.
• Introduce special safety concerns or ones that are deemed complex in nature.

When required by NBC-AE Division C 2.4.2. or deemed necessary by the Authority Having Jurisdiction, schedules of Professional Involvement shall be provided for all applicable professions involved in the project.

Provide the following Professional Schedules at the time of application:

• Schedule A
• Schedule B

Provide the following Professional Schedules at time of building completion (occupancy inspection)

• Schedule C-1
• Schedule C-2
• Schedule C-3

Site plans need:

• Building address
• North arrow
• Key plan
• Identification of adjacent suites and uses
• Front entrance
• Accessible parking stalls

Architectural floor plans need:

• Floor, wall and unit layouts
• Room name and use
• Exit stairs, doors and corridors with dimensions
• Construction assemblies including suite demising walls complete with fire resistance ratings as required
• Washrooms, change rooms, shower rooms and hygiene stations including accessibility provisions
• Window and door locations with fire resistance ratings as applicable

Architectural elevations if applicable:

• Any new openings in exterior walls
• Size and location of windows, including operable units
• Spatial separation calculations for limiting distances

Notes:

• Elevations are required when alterations to the exterior walls of a building are made, including new doors or windows and any outdoor amenitiy spaces.
• Site plans must indicate the suite being altered, entrances, exits and any exterior stairs or walkways. 
• Fire resistance ratings of assemblies can have various requirements and are critical for Code compliance verification. Specific fire resistance ratings must be indicated for wall assemblies and structural components. 
• Floor plans must show all doors, windows and layouts to determine means of egress and exits.

For projects that require structural drawings, include the following information:

• Size of openings 
• Information on the lintels, beams or other new support structure, including how this will transfer load to the remaining structure or ground
• Details on structural member sizes, connections and load parameters

Note:

• Structural drawings are required for the support of new and modified mechanical equipment, openings in exterior and load bearing walls, and new openings in existing floors not supported by the ground. All structural drawings must include design load calculations. 
• For any design outside the parameters allowed under Part 9 of the NBC (AE), the design must be prepared by and bear the stamp and seal of a professional engineer registered in the province of Alberta.

Mechanical drawing sets need:

• Any new heating, cooling and ventilation equipment and specifications
• Duct penetrations of fire rated floors/fire separations
• Plumbing fixtures
• Location and number of sprinkler heads
• Fire alarm systems, if applicable
• Sprinkler systems, if applicable

Notes:

• Mechanical information can be included in architectural drawings.
• Mechanical drawings must indicate the type and location of equipment and indicate any ducts penetrating fire separations, including fire and smoke damper locations where applicable.
• Sprinkler drawings must indicate sprinkler design standard (ex. NFPA 13) and bear the stamp and seal of a professional engineer registered to practice in the province of Alberta.
• Certain specialized mechanical ventilation systems (such as NFPA 96 systems for the venting of kitchen cooking exhaust) require professional design and the drawings must bear the stamp and seal of a professional engineer registered to practice in the province of Alberta.

Electrical drawing sets need:

• Lighting and plug location layouts
• Smoke and CO alarm locations
• Fire alarm systems, if applicable

Note:

• Electrical information can be included in architectural drawings.
• Lighting layouts and energy Code calculations must be provided, including any required lighting controls.
• Electrical drawings must indicate location of smoke and CO alarms, emergency lighting and exit sign locations as required.
• If a sprinkler and/or fire alarm system is installed, the design must be prepared by and bear the stamp and seal of a professional engineer registered in the province of Alberta.

• For tenant improvement work that does not alter exterior walls, energy Code compliance must be demonstrated for new lighting, HVAC and Service water systems and components This may be done though performance or prescriptive compliance as governed by the NECB.
• For tenant improvement work that includes alterations to exterior walls, compliance with the building envelope requirements (Part 3) of the NECB is also required for new or modified components in addition to the above.
