1. A contractor is planning to demolish a two-story row house in Philadelphia that is 35 feet tall and covers 8,000 square feet of lot space. According to the City of Philadelphia's definition, what type of demolition license is required for this project? A. Class A Demolition License B. Class B Demolition License C. No license is required for residential buildings D. An Interior Demolition Permit Answer: B. Rationale: The Philadelphia Department of Licenses and Inspections (L&I) defines a Class B demolition project as the complete demolition of a building that is no more than three stories, has a maximum height of 40 feet, and a maximum area of 10,000 square feet . This project meets all those criteria, thus requiring a Class B license. A Class A license is for larger structures exceeding these limits . 2. Under the Philadelphia Administrative Code, Title 4, what is the formal definition of a "Major Building" that would necessitate a Class A demolition license? A. Any building located in a historic district B. A building with a total area of more than 20,000 square feet C. A building that is more than 3 stories high, more than 40 feet tall, or covers 10,000 square feet or more D. Any commercial building over 50 years old Answer: C.Rationale: The Philadelphia Administrative Code (A-1001.1) provides a specific definition for a "Major Building," which triggers the need for a Class A demolition contractor. It is defined as a structure exceeding three stories, exceeding 40 feet in height, or covering 10,000 square feet or more of lot space . Projects not meeting this "Major Building" threshold generally fall under the Class B demolition scope . 3. Before applying for a demolition permit, a Class B contractor must identify a "Demolition Supervisor" on their license application. What is the primary qualification that this individual must meet? A. Hold a valid OSHA 30 safety training certificate B. Have at least 10 years of experience in general construction C. Provide proof of successful completion of the Philadelphia Demolition Contractor Examination (Class B) D. Own at least 25% of the contracting company Answer: C. Rationale: For a demolition contractor's license, the named "Demolition Supervisor" is responsible for developing site safety plans. The key requirement is that this individual must have successfully passed the Philadelphia Demolition Contractor Examination (Class A or B) administered by the International Code Council . While an OSHA 30 certification is required for the separate role of "Site Safety Manager," it is not the defining qualification for the Supervisor . 4. According to official City of Philadelphia requirements, what is the minimum amount for a surety bond that a contractor must obtain to be issued a Class B Demolition Contractor's License? A. $2,000,000 B. $50,000 C. $10,000 D. $25,000 Answer: C. Rationale: The City of Philadelphia mandates a specific license bond for contractors toensure financial responsibility. For a Class B Demolition Contractor's License, the required bond is $10,000. In contrast, a Class A contractor must secure a significantly higher bond of $50,000 . 5. A Class B demolition contractor is preparing their application. They must designate a "Named Demolition Site Safety Manager." What is the minimum qualification for this role regarding safety training? A. A bachelor's degree in construction management B. Proof of completion of an OSHA 30 safety training course within the last five years C. A certification from the National Association of Demolition Contractors D. A valid Pennsylvania driver's license Answer: B. Rationale: The role of the Site Safety Manager is to ensure safe practices on-site and compliance with the safety plan. The City requires proof that this individual has completed an OSHA 30 safety training course, and it must have been completed within five years of the application date to ensure their knowledge is current . 6. What is the primary purpose of requiring a surety bond (e.g., $10,000 for Class B) for demolition contractors in Philadelphia? A. To guarantee the contractor's profit margin on the project B. To provide insurance for the contractor's employees in case of injury C. To ensure the contractor can pay for damages or comply with the law, protecting the city and property owners D. To cover the cost of the demolition permit application fee Answer: C. Rationale: A surety bond is a three-party agreement between the principal (contractor), the obligee (the City of Philadelphia), and the surety company. It acts as a financial guarantee. If the contractor fails to perform the work according to regulations or causes damage, a claim can be made against the bond to cover losses, thus protecting the public and the city .7. In addition to the general liability insurance, what specific type of insurance must a Class B demolition contractor in Philadelphia provide with their license application? A. Earthquake and geological hazard insurance B. Professional liability (Errors and Omissions) insurance C. Automobile Liability Insurance with a minimum of $300,000 D. Cyber liability insurance Answer: C. Rationale: The City's licensing requirements specify several types of mandatory insurance. Along with General Liability ($2,000,000 per occurrence) and Worker's Compensation, a contractor must provide proof of Automobile Liability Insurance with a minimum coverage of $300,000 . This covers vehicles used for the demolition project. 8. A Philadelphia property owner wants to remove several non-load-bearing interior walls and update the kitchen in their row house. They plan to hire a contractor for this work. Which statement is true regarding the need for a demolition license? A. The contractor must hold a Class B Demolition License because it involves tearing down walls. B. The contractor must hold a Class A Demolition License because it is a residential structure. C. No demolition license is required for this interior or partial demolition work. D. The property owner must obtain a demolition permit themselves before any work begins. Answer: C. Rationale: The City of Philadelphia explicitly states that a Demolition Contractor's License (Class A or B) is not required for interior or partial demolition . This type of work can be performed under other appropriate contractor licenses (e.g., a general building contractor license), though building permits would still be required for the renovation work.9. A Class B demolition contractor is renewing their annual license. The named Demolition Site Safety Manager's OSHA 30 certification has expired. What action can be taken to meet renewal requirements without retaking the entire OSHA 30 course? A. The Site Safety Manager can take 30 hours of continuing education credits in construction or demolition safety. B. The Site Safety Manager can be replaced by the Demolition Supervisor for this role. C. The contractor can submit a letter explaining the expiration and promising to renew it within 60 days. D. The Site Safety Manager must retake and pass the entire OSHA 30 course immediately. Answer: A. Rationale: Philadelphia's L&I provides a specific pathway for license renewal regarding the OSHA 30 requirement. If the department has already accepted a supervisor's OSHA 30 Construction and Safety certificate, they can fulfill the requirement by completing 30 hours of continuing education credits in construction or demolition safety instead of retaking the full OSHA 30 course . 10. What is the first and most critical step in the pre-demolination planning process before any physical work begins or a permit is even applied for? A. Ordering the primary demolition excavator B. Conducting a comprehensive site evaluation to identify hazards C. Notifying all neighbors of the upcoming demolition date D. Hiring a waste hauling company for debris removal Answer: B. Rationale: All demolition planning must begin with a thorough site evaluation . This assessment identifies potential safety hazards (structural instability), environmental concerns (asbestos, lead), and the presence of utilities. This information is foundational for developing the site safety plan, selecting the right demolition method, and completing the permit application accurately. All other steps follow this initial assessment.11. During the pre-demolition site assessment, which two hazardous materials are most critical to identify in a older Philadelphia building due to specific federal and local regulations? A. Mold and mildew B. Asbestos and lead-based paint C. Treated lumber and copper wiring D. Fiberglass insulation and drywall Answer: B. Rationale: In older structures, particularly in a historic city like Philadelphia, the presence of asbestos-containing materials (ACMs) and lead-based paint is a primary concern . Both are regulated by the EPA (for asbestos) and other agencies due to their severe health risks. A thorough survey is required to locate these materials so they can be safely abated before any demolition that would disturb them. 12. According to standard demolition practices, what is the primary purpose of "salvage" and "deconstruction" in a demolition project? A. To increase the overall cost and timeline of the project for billing purposes B. To remove hazardous materials from the site before demolition begins C. To recover reusable or recyclable materials, diverting waste from landfills D. To prepare the site for the use of explosives Answer: C. Rationale: Salvage refers to the process of recovering materials for reuse or recycling . Deconstruction is a more systematic approach to dismantling a building specifically to preserve materials for reuse . These practices are driven by sustainability goals and, in some jurisdictions, by waste diversion regulations. They are distinct from hazardous material abatement. 13. A demolition plan for a Class B building in Philadelphia must include details of adjacent property and structures. What is the primary safety concern driving this requirement? A. To ensure the neighboring buildings have adequate trash disposal access.B. To ensure the new construction planned for the site will match the neighbors' aesthetics. C. To plan the demolition in a way that ensures adjacent properties are not damaged. D. To provide utility companies with a map for future connections. Answer: C. Rationale: The requirement to document adjacent properties in the demolition plan is fundamentally a safety and liability measure . The plan must demonstrate how the contractor will protect neighboring structures from damage caused by debris, vibration, or potential collapse during the demolition process. This includes measures like shoring or bracing if necessary.
