Final answer:
Before demolition, inspection for hazards, utility disconnection, a demolition plan, regulatory approvals, notifications to the community, and safety measures for workers are required.
Step-by-step explanation:
Before starting demolition on a building, several important steps must be taken to ensure safety and compliance with local building codes and regulations. These steps typically include a thorough inspection to determine the presence of hazardous materials like asbestos or lead, which require special handling for removal.
Furthermore, utilities such as water, gas, and electricity must be disconnected to prevent accidents during demolition. A detailed demolition plan must be developed, including a waste disposal strategy for the debris. Approval from the relevant authorities is necessary, which involves securing necessary permits. It's also vital to inform nearby residents and businesses to minimize disruptions and ensure safety. Lastly, appropriate safety measures and equipment are essential to protect the workers involved in the demolition process.
