A leak on the top floor, a poorly anchored rooftop unit, a stained ceiling or an office reconfiguration: in a commercial building, the work has to be done without interrupting operations or exposing employees and visitors.
You cannot close your offices for weeks. The work has to be divided by zones and time slots.
Dust, noise, air quality, older materials that may contain asbestos or lead: your employees must be protected.
A membrane at the end of its life, blocked drains or poorly secured mechanical units cause leaks right above the workstations.
Your landlord, your property manager or your insurer ask for proof: licence, certificates, insurance, work methods.

According to the CNESST, the principal contractor sends the notice of opening of a construction site when it is required, at least 10 days before activities begin, and the principal contractor, employers and workers all have a role to play in prevention.
