This is the typical order of operations in a typical building power shutdown and re-energize protocol.
Preparation for Power Shut Down
1 | Building Management Staff – Contacts Fire Dept to have Building put on ‘Test’; regularly confirms status with Fire Dept until Fire Suppression Systems are fully functional. Coordinates all communication with leaseholders and occupants including proper notifications and pertinent instructions. Notice to leaseholders/occupants will be distributed 5 Days in advance of the scheduled shutdown.
2 | ARS Project Management – Coordinate with ownership, building superintendent/property management, tenants, city officials, Toronto Fire and ESA.
3 | Ensure necessary arrangements are made with any businesses that may be impacted including temporary power to adjacent spaces to maintain functionality during power disconnect
4 | Complete fire stopping work to Electrical Room and any other adjacent/proximate mechanical rooms where conduit penetrate walls/ceilings and risers as required by Fire Services.
5 | Site Plan required from Electrical company regarding placement of equipment.
6 | Order/arrange delivery of appropriate Generator(s), temporary distribution panels and switchgear to run emergency lighting, exit lighting, and temporary lighting in stairwells and common areas. Specifications for generator(s) based on Electrical contractor’s requirements.
7 | Temporary Exterior Lighting set up on all sides of the Building, close to underground parking Entrances/Exits. 8 | Arrange appropriate Security coverage for Fire Watch (proper protocols to be followed), unsecured building access points, exterior equipment, mechanical rooms and other areas where work is underway.
9 | Request Vulnerable Occupants list from Building Management. Ensure vulnerable occupants receive snacks and water at least twice a day.
10 | ARS personnel to Lock/bar Corridor Garbage Chute Doors so that chute is not operational during Power Shut Down. Place Notice on Chute Doors requesting occupants to leave garbage bags near the door which will be regularly removed by ARS staff. Advise Building Management to de-activate Garbage Compactor once chute doors are locked. ARS crew required to constantly collect garbage and carry to garbage bin until power has been re-established and the Chute Compactor is online. This will have to be done regularly to ensure corridor carpet/wall finishes are not damaged (elevators will not be in service).
11 | ARS personnel in place to receive generators/temporary panels/switchgear and install fencing as required.
12 | Electrical contractor runs cabling from Electrical Room to Temporary Distribution Panels, installs temporary lighting, completes pre-connection to Emergency and Exit Lighting.
13 | Underground Parking Doors to be fixed in the open position before power shut down (if applicable).
14 | Arrange for hot and cold beverages and snacks in the lobby for the duration of the shut down at 7:00 AM each morning and 6:30 pm each evening.
Power Shut Down
1 | Electrical contractor Foreman signals Start.
2 | Elevator company Tech brings elevators to the sub-basement level.
3 | HVAC Company makes sure the controller is online and completely operational. Switches Heat Controls to manual and shut down all heating panels to all floors. Ensures the controller database is backed up and tests all digital outputs and relay switch points.
4 | Fire Suppression company: a) Alarm tech puts the entire system on bypass) b) Sprinkler tech required to monitor system and to ensure pump valves have adequate air pressure; shuts down pumps if needed. Both techs remain on-site for as long as needed. Depending on the situation techs can leave site providing they can return with one hour’s notice.
5 | Plumber – Shuts down pumps to the Domestic/Boiler System if required. In some cases, water lines may need to be drained (e.g. potential for freezing during winter months). Plumber remains on-site during the process.
6 | Electrical contractor powers down Electrical System.
7 | Toronto Hydro opens switches (Disconnects city power).
8 | Third-party Electrical Testing company conducts di-electric testing of main distribution components.
9 | Electrical contractor does the necessary inspection, maintenance, repair/replacements to Electrical System including Suites.
10 | Electrical contractor foreman gives at least one-hour notice before the electrical system will be re-energized so that all mechanical partners will be in position for Reinstatement of the Electrical System.
Reinstatement of Electrical System
1 | Electrical contractor Foreman signals the ‘start of reinstatement of power’ process.
2 | Toronto Hydro Closes Switches (turns on power).
3 | Plumber – if water was previously drained, city water is reintroduced.
4 | Fire Suppression company does any necessary preparation/monitoring work.
5 | Electrical contractor re-instates Power (coordinates with ESA)
6 | Security personnel listen at each apartment door for sounds of potential water escape due to faucets mistakenly left open (average 10 incidents per building). In cases where there is a suspected water escape, security guard knocks on the door. If an occupant does not open the door, a security guard is to call the Security Supervisor who will forward the information to the Building Superintendent and an ARS Representative to open the door and investigate possible water escape.
7 | Clean up crew on Standby to clean up possible water release.
8 | Plumber – Reinstates water pumps and monitors system (may need to turn off water system temporarily if there is the danger of electrical system being impacted by water escape).
9 | Sprinkler techs make any necessary changes to the fire suppression system and monitor the system’s re-activation; alarm tech re-activates fire suppression alarm system.
10 | HVAC company ensures the controller is back online, rechecks all points and turns on heating to all floors and tests digital outputs and relay switches again.
Post Reinstatement of Electrical System
1 | Unlock or Remove barriers from Garbage Chute doors/hatches; advise Building Management Garbage Compactor can be reactivated.
2 | Procure Verification Report from Fire Suppression company as soon as possible and deliver it to the Fire Department.
3 | Once Verification Report is approved by the Fire Department, reduce/eliminate fire watch per Fire Department’s specifications.
4 | Removal of Generators and Temporary Power/Distribution Equipment, Temporary Exterior lighting, Fencing, etc.
