Office Tenant Improvement Electrical

A modern office needs more than receptacles around the perimeter walls.

Electrical planning may need to account for:

• Private offices

• Open workstations

• Conference rooms

• Huddle rooms

• Reception areas

• Breakrooms

• Copy and print areas

• Training rooms

• Phone rooms

• AV systems

• Server and IT equipment

• Specialty office equipment

Each area uses power differently.

OTC coordinates the electrical layout around the actual furniture, equipment, and operation of the office.

Open offices frequently require power away from the walls.

Depending on the furniture system and building conditions, power may be delivered through:

• Furniture whips

• Floor boxes

• Poke-through devices

• Underfloor systems

• Overhead pathways

• Columns or walls

OTC coordinates workstation power with the furniture plan so electrical connections are installed where they are actually needed.

Planning this early helps avoid extension cords, exposed wiring, or expensive changes after furniture is delivered.

Conference rooms often need electrical and technology connections in the center of the room rather than only along the walls.

Floor boxes may provide connections for:

• Receptacles

• Displays

• Conference tables

• AV equipment

• Data pathways

• Presentation systems

Installing a floor box in an existing building can require significantly more work than it appears on the floor plan.

Depending on the building construction, installation may involve:

• Concrete cutting

• Trenching

• X-ray or scanning requirements

• Conduit routing

• Coordination with flooring

• Building restrictions

OTC identifies these conditions early so the floor-box scope is properly coordinated before construction begins.

Conference rooms have become some of the most electrically intensive areas in a modern office.

They may require power for:

• Wall-mounted displays

• Video-conferencing systems

• Table connections

• Speakers

• Cameras

• Media boxes

• Wireless presentation equipment

• AV racks

OTC coordinates the line-voltage electrical requirements with the low-voltage or AV contractor so power and pathway locations match the equipment being installed.

Private offices and smaller meeting rooms may require:

• General receptacles

• Dedicated equipment power

• Lighting

• Dimming

• Occupancy sensors

• Display power

• Data pathways

Even small rooms should be coordinated around furniture placement and technology before walls are closed.

Office tenant improvements often involve significant lighting changes.

OTC can install or modify:

• LED fixtures

• Recessed lighting

• Linear fixtures

• Decorative lighting

• Conference room lighting

• Task lighting

• Emergency lighting

• Exit signage

Lighting can be coordinated with the reflected ceiling plan and architectural layout so fixtures align properly with offices, conference rooms, corridors, and work areas.

Modern office lighting may incorporate:

• Occupancy sensors

• Vacancy sensors

• 0–10V dimming

• Daylight controls

• Zoned switching

• Time-based controls

Different areas of the office can have different control requirements.

For example, a private office may use occupancy control while a conference room may need both occupancy sensing and dimming.

OTC verifies that the fixtures and controls are compatible before installation.

Breakrooms often require more electrical capacity than customers expect.

Equipment may include:

• Refrigerators

• Microwaves

• Coffee machines

• Dishwashers

• Ice makers

• Water dispensers

• Vending equipment

Several of these loads may require dedicated circuits.

OTC reviews the equipment requirements so the breakroom is properly circuited instead of placing multiple high-demand appliances on an existing convenience circuit.

Office equipment can create concentrated electrical loads.

Copy and print areas may contain:

• Large multifunction printers

• Copiers

• Shredders

• Production printers

• Mailing equipment

• Specialty equipment

OTC determines whether equipment can use existing circuits or should receive dedicated power.

Existing office buildings frequently contain years of previous tenant modifications.

We may encounter:

• Abandoned circuits

• Incorrect panel schedules

• Hidden junction boxes

• Existing furniture feeds

• Circuits serving multiple areas

• Old lighting controls

• Previous tenant wiring

• Limited panel space

That is why office TI work often requires field verification in addition to reviewing the drawings.

The plans show what the new office needs.

The existing building tells us what we actually have to work with.

A tenant improvement does not automatically require removing every existing electrical component.

Depending on condition and the new layout, existing systems may be reused or modified, including:

• Panels

• Branch circuits

• Lighting

• Home runs

• Emergency circuits

• Existing pathways

Reusing appropriate infrastructure can reduce unnecessary demolition and project cost.

The key is verifying that the existing system is suitable for the new use.

Adding offices, breakroom equipment, floor boxes, and new electrical loads can increase the demands on the existing panel.

OTC evaluates:

• Available breaker space

• Existing connected loads

• Feeder capacity

• Panel condition

• Proposed new loads

A panel that is out of breaker spaces does not automatically mean the entire electrical service needs to be upgraded.

Depending on the existing capacity, a subpanel or distribution modification may solve the problem.

Office electrical installation has to coordinate closely with:

• Framing

• Drywall

• ACT ceilings

• Furniture systems

• Millwork

• Flooring

• HVAC

• Plumbing

• Low-voltage

• AV contractors

A receptacle installed six inches from where the furniture vendor expected it can become a significant problem after finishes are complete.

Good coordination early in the project prevents those conflicts.

Some office tenant improvements happen while employees continue working in the building.

OTC can coordinate:

• Phased work areas

• After-hours construction

• Planned shutdowns

• Temporary power

• Ceiling access

• Daily cleanup

around the customer's operating schedule.

Disruptive activities can be moved outside normal working hours when necessary while other portions of the work continue during the day.

A complete office TI electrical scope may include:

• Electrical demolition

• Circuit tracing

• Temporary power

• New branch circuits

• Workstation power

• Floor boxes

• Conference room power

• Breakroom circuits

• Lighting

• Lighting controls

• Emergency lighting

• Panel modifications

• Equipment connections

• Device installation

• Testing

• Panel labeling

• Punch-list corrections

OTC coordinates the electrical work throughout the construction sequence instead of treating each item as a separate service call.
