A tenant improvement project can be a straightforward refresh, or it can affect nearly every essential system in a commercial building.
New walls, equipment, workstations, washrooms, kitchens, lighting, access points, storage layouts, and occupancy changes can all create requirements beyond the visible construction work. Electrical capacity may need to change. HVAC systems may need to serve a different layout. Plumbing fixtures and drainage may need to be added or moved. Fire protection devices may need to be reviewed. Security and access control may need to be updated.
For Edmonton property managers and building owners, the best time to identify those requirements is before construction begins.
What Is a Tenant Improvement Project?
A tenant improvement, often called a TI, is work completed to prepare, modify, or upgrade a commercial space for a new or existing tenant.
Projects can range from modest changes to major renovations. They may include:
- New offices, meeting rooms, or partitions
- Retail fit-outs
- Restaurant or food-service spaces
- Medical, professional, or institutional spaces
- Warehouse and industrial-area reconfigurations
- New washrooms, staff rooms, or kitchenettes
- Lighting and electrical upgrades
- HVAC modifications
- Fire protection changes
- Security, access control, and intercom installations
- Changes to occupancy or how the space is used
The visible result may be a finished tenant space. Behind the walls and ceilings, however, the project may require coordination among electrical, mechanical, plumbing, fire protection, security, and construction teams.
Start With the Building Systems
Before finalizing layouts, finishes, or construction schedules, review the systems that serve the space.
This helps avoid discovering late in the project that a new wall affects sprinkler coverage, an electrical panel does not have the capacity for new equipment, a washroom requires additional plumbing work, or an HVAC system is not configured for the new layout.
A practical early review should include:
- Electrical capacity and distribution
- Lighting, emergency lighting, and exit signage
- HVAC capacity, airflow, ventilation, heating, cooling, and controls
- Plumbing, drainage, fixtures, water heating, and specialty requirements
- Fire alarm devices, sprinkler systems, extinguishers, and suppression equipment
- Security, access control, cameras, intercoms, and low-voltage infrastructure
- Mechanical-room, electrical-room, and rooftop-equipment access
- Existing service records, known deficiencies, and previous repair recommendations
Karlen-Kada provides integrated mechanical, electrical, fire protection, and security services for commercial properties, allowing building teams to review connected systems together rather than treating each trade as a separate issue.
Confirm the New Space Will Have Enough Electrical Capacity
Electrical needs can change significantly when a tenant changes.
A space that once operated as a basic office may need to support commercial kitchen equipment, medical equipment, manufacturing tools, data infrastructure, additional lighting, new HVAC equipment, security systems, charging stations, or higher occupant loads.
Before work begins, review:
- Available panel capacity
- Condition and age of the existing electrical equipment
- New equipment loads
- Lighting requirements
- Emergency lighting and exit-sign needs
- Receptacle locations and quantity
- Data, communications, and low-voltage infrastructure
- Security and access-control power requirements
- Whether temporary wiring or extension cords are being used as a permanent solution
- Requirements for future expansion
Electrical capacity should be assessed before the project design is finalized. If the existing system cannot support the planned use, it is easier to address that early than after walls are closed and equipment has been ordered.
Karlen-Kada provides commercial electrical design-build services, panel upgrades, installations, and ongoing support for Edmonton businesses and commercial properties.
Review HVAC, Ventilation, and Comfort Needs
A new layout can change how a space heats, cools, and ventilates.
Partitions can affect airflow. Higher occupancy can increase cooling demand. New equipment can generate heat. A commercial kitchen may require specialized ventilation. A former storage area may become an occupied workspace. Changes to operating hours can require adjustments to HVAC schedules and building controls.
Before construction, consider:
- Will the existing HVAC system serve the new layout effectively?
- Will new walls affect supply and return airflow?
- Is the space changing from low occupancy to high occupancy?
- Will the tenant add heat-producing equipment?
- Are additional ventilation or exhaust requirements needed?
- Does the project involve a commercial kitchen, laboratory, workshop, or other specialized use?
- Will thermostats, sensors, dampers, controls, or zones need to change?
- Are make-up air and exhaust systems appropriate for the intended use?
- Will the work affect rooftop units, air handlers, boilers, or other shared equipment?
Do not assume that a system that worked for the previous tenant will automatically be appropriate for the next one. A commercial HVAC assessment can identify whether the space needs adjustments, repairs, added capacity, ventilation changes, or control updates.
Karlen-Kada provides commercial mechanical installations for HVAC, plumbing, gas fitting, boilers, ventilation, and custom building-system requirements.
Plan Plumbing Changes Early
New washrooms, kitchenettes, staff areas, food-service equipment, medical spaces, laundry facilities, drains, or water-using equipment can all require plumbing work.
Consider:
- Water supply requirements
- Drainage and venting needs
- Floor drains
- Fixture locations
- Hot-water demand
- Water-heater capacity
- Backflow prevention requirements
- Grease management for commercial kitchens
- Sump-pump or lift-station impacts in below-grade spaces
- Access to plumbing shut-offs and service points
A plumbing issue discovered after the finishes are complete can lead to avoidable demolition and project delays. Early review helps ensure the design accounts for both the visible fixtures and the infrastructure behind them.
Do Not Overlook Fire Protection
Fire protection systems are designed around a building’s layout, occupancy, access points, and risks. A tenant improvement project can affect fire alarms, sprinklers, emergency lighting, exit signs, extinguishers, commercial kitchen suppression systems, and access to fire protection equipment.
Review whether the project may affect:
- Fire alarm device locations and coverage
- Pull stations, horns, strobes, speakers, and annunciator access
- Fire sprinkler head placement, clearance, and access
- Sprinkler piping or valves
- Emergency lighting and exit-sign visibility
- Fire extinguisher location and accessibility
- Kitchen suppression equipment
- Fire alarm monitoring and communication systems
- Fire protection equipment that could be blocked by walls, storage, displays, or new finishes
Sprinkler heads should never be painted, covered, obstructed, or altered during construction without qualified fire protection oversight. Paint can affect sprinkler operation, and affected sprinkler heads should be assessed by a qualified professional.
Karlen-Kada provides fire alarm, sprinkler, emergency lighting, extinguisher, kitchen suppression, backflow testing, and fire-protection service for Edmonton buildings.
Coordinate Security and Access Control
A tenant improvement project may also change how people enter, move through, and secure the space.
New doors, tenant areas, reception spaces, storage rooms, parkade access, common areas, and restricted zones may require changes to access control, cameras, intercoms, wiring, and monitoring.
Review:
- New or changed entry points
- Access-control requirements
- Door hardware and electrified locking needs
- Intercom and video-entry systems
- Camera coverage
- Security-system wiring
- Connectivity and low-voltage infrastructure
- Access to electrical and communications equipment
- How security changes affect emergency egress
Security upgrades should be planned alongside electrical, door, construction, and fire-protection work. Adding them late in the project can create extra cost, incomplete coverage, or unnecessary disruption.
Karlen-Kada provides commercial security systems, access-control solutions, intercoms, surveillance, and integrated building services for Edmonton properties.
Build a Realistic Project Timeline
Tenant improvements often involve multiple contractors, approvals, lead times, inspections, access requirements, and tenant deadlines.
A realistic timeline should account for:
- Early site and system assessment
- Scope development
- Design and coordination
- Permits and approvals where required
- Equipment ordering and lead times
- Construction sequencing
- Electrical, mechanical, plumbing, fire protection, and security work
- Required inspections and testing
- Tenant access and business operations
- Final documentation and system handover
Do not assume every component can be sourced or installed immediately. Early planning gives your team more options if equipment, specialty parts, or coordinated trade work is required.
Ask the Right Questions Before Work Starts
Before approving the project, make sure the project team can answer:
- What building systems will this work affect?
- Does the electrical system have the required capacity?
- Will the HVAC system provide appropriate comfort and ventilation after the layout changes?
- Are plumbing, drainage, water-heating, or backflow requirements changing?
- Will fire alarm, sprinkler, emergency-lighting, or suppression systems need to be modified?
- Are fire protection devices and equipment accessible after the renovation?
- How will security, access control, cameras, and intercoms be updated?
- What permits, testing, inspections, and documentation are required?
- Which contractor is coordinating work when more than one building system is involved?
- How will tenant disruption and building access be managed?
- What maintenance records or closeout documents will the property team receive?
These questions help prevent the project from becoming a series of last-minute corrections.
