Replace the YouTube link above with your Division 02 study video.

• This division is all about understanding the site before you start building.
• Always review selective demolition notes carefully — they can be costly.
• Soil and site surveys may be in appendices or referenced documents.
• Check for hazmat removal requirements like lead, asbestos, or mold.
• Environmental reports must be verified before submitting bids.

1. What is the purpose of a site survey in Division 02?
   Answer: To assess site conditions such as elevation, existing structures, and soil characteristics.
2. What is the difference between selective and total demolition?
   Answer: Selective demo removes specific parts while retaining others; total demo removes everything.
3. What environmental hazards are commonly addressed?
   Answer: Asbestos, lead-based paint, contaminated soil, and groundwater.
4. What must be considered with utility relocation?
   Answer: Whether gas, electric, or water lines must be rerouted or temporarily replaced.
5. Why is coordination with existing structures important?
   Answer: To protect nearby buildings and ensure safe tie-ins, bracing, or access restrictions.

Division 02: Dealing with What’s Already There

🔹 Key Teaching Points

1️⃣ Surveying and Site Investigation

• Includes soil reports, existing building surveys, and topography.
• Estimators should review closely for:
  • Access issues
  • Elevation changes
  • Underground obstructions

2️⃣ Selective and Total Demolition

• Division 02 outlines:
  • What stays vs. what goes
  • Sequencing for demo
  • Disposal requirements and recycling

3️⃣ Environmental and Hazardous Material Remediation

• Often includes:
  • Asbestos
  • Lead paint
  • Contaminated soil
• Estimators must flag scope exclusions or testing responsibilities.

4️⃣ Site Utilities and Relocation

• Notes any relocation of:
  • Gas
  • Electrical
  • Water/sewer services
• May require temporary service or rerouting during construction.

5️⃣ Coordination
