While tenant improvement work may often be completed without professional involvement, industrial occupancies often require professional involvement. This is due to complexity, unique and hazardous operations or the equipment required for the business. 

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: 

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

• Any high hazard industrial use, like distillery, spray painting facility, flammable goods manufacturing, dry cleaning plants, or grinding and milling processes that produce combustible dust.
• Any industrial occupancy with an area greater than 500 sq. m.
• Specialized processes that produce volatile vapours or gases, and storage areas containing flammable or combustible liquids.

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 that shows the exact location of the proposed tenant 
• Identify location of adjacent suites and uses 
• Main floor elevation and geodetic grades 
• Front entrance 
• Accessible parking stalls 
• Property lines, building outline and setbacks with dimensions, if changing occupancy 
• Any retaining walls greater than 1.2 m in height, foundation location, utility rights-of-way and site servicing, if altering building site or parking

Architectural floor plans need: 

• Floor, wall and unit layouts 
• Room name and use 
• Means of egress and travel exits
• Washrooms, changerooms, shower rooms and hygiene stations including accessibility provisions 
• Identification of specific equipment installations like spray booths, welding rooms and storage areas for combustible and explosive materials
• Exit stairs, doors and corridors with dimensions, if applicable 
• Window and door locations with fire resistance ratings, if applicable 
• Construction assemblies including suite demising walls complete with fire resistance ratings, if required

Architectural elevations, if applicable need: 

• Any new openings in exterior walls 
• Size and location of windows, including operable units 
• Exterior cladding and finishes 
• Building height 
• Grade at the building face 
• Spatial separation calculations for limiting distances 
• Balconies, eaves and other projections, if applicable 

Architectural cross-sections, if adding a mezzanine or new floor area, need: 

• Floor heights and geodetic elevations 
• Floor and roof assembly constructions including fire resistance ratings, if applicable 

Notes: 

• Elevations are required when alterations to the exterior walls of a building are made, including new doors or window, and any outdoor amenity spaces or mechanical equipment is installed. 
• 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. In addition, many industrial uses require non-combustible construction, so construction type is also required. The fire resistance rating of a given assembly shall be referenced by a ULC listed assembly or appendix D of the building code.
• Floor plans must show all doors, windows and layouts to determine means of egress and exits. 
• Exterior cladding requirements impact fire spread and combustibility of walls and need to be indicated 

Structural drawing sets need: 

• Structural drawing sets are required for floors above grade supporting new equipment or for alterations that create new openings in existing floors.
• Roof structural drawings are required if new or upgraded mechanical equipment is installed. This is particularly true for new or modified equipment that require new openings in the roof.
• Design load calculations for any structural drawings must be provided.

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.  
• The design must be prepared by and bear the stamp and seal of a professional engineer registered in the province of Alberta and be completed in accordance with Part 4 of the NBC (AE). 
• New openings in floors 
• Exterior alterations 

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 
• Permanently installed process equipment, including a description of the processes and materials the equipment is expected to utilize
• Location and number of sprinkler heads 
• Fire alarm systems, if applicable  
• Sprinkler systems, if applicable 

Notes: 

• Mechanical drawings must indicate the type and location of new and modified equipment, and indication of any ducts penetrating fire separations, including fire and smoke damper locations where applicable.
• Mechanical drawings must indicate the type and location of equipment and indicate any ducts penetrating fire separations, including fire damper locations where applicable. 
• Some specialized mechanical ventilation systems (like spray booth ventilation and large-scale dust collection) require professional design and the drawings must bear the stamp and seal of a professional engineer registered to practice in the province of Alberta. 
• Many industrial occupancies require specific sprinkler or fire protection measures related to specific industrial processes or combustible storage requirements. It is recommended to consult NBC (AE) 1.3.1.2. for a list of reference standards related to these specific requirements.
• Sprinkler system 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. 
• If utilizing a sprinkler system that requires a fire alarm system (ex. NFPA 13), those drawings must also be submitted. 

Electrical drawing sets need: 

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

Note: 

• Lighting layouts and energy code calculations must be provided, including any required lighting controls. 
• Electrical drawings must indicate location of smoke detection devices 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. 
• Process equipment may often be excluded from NECB compliance. A professional can provide guidance on these exclusions.
