2. Physical Layout Building Plans Architectural Plans Structural Plans Mechanical Plans Plumbing Plans Electrical Plans HVAC Plans Understanding Building Systems

3. Understanding Building Systems: Physical Layout Age and use of the building. Materials of construction. Full or partial basements and location of piping, pipe chases and steam tunnels. Location of electrical/mechanical rooms in multistory buildings. Location of central power plants and utility tunnels in multiple building complexes.

4. Understanding Building Systems: Building Plans Floor plans are basis for mechanical, plumbing & electrical drawings Include elevations (vertical) Details (Isolated areas of construction) Sections (Cut vertically) Notes (General or specific) Schedules (Info regarding building)

5. Understanding Building Systems: Architectural Plans ID’s materials used in floors walls, doors, windows etc. ID’s inaccessible bldg. products & any ACM/PACM ID’s tunnels, pipe chases, attics & accessibility prior & during remediation Review previous abatement records & room #’s accuracy

6. Understanding Building Systems: Structural Plans Details of floors, framework and foundations Structural beams, columns and slabs Wood framing Drywall/gypsum or Plaster Concrete versus steel beams

7. Understanding Building Systems: Mechanical Plans Based on building floor plans HVAC schematic or system design/diagram to indicate the HVAC system operation. Ductwork routing and piping systems. Details, notes, schedules, sections and elevations. Boilers, radiators and air handling units.

8. Understanding Building Systems: Plumbing Plans Location of tanks, pipes & drains for supply & return fluids, waste & pressure equalizer pipes Locates remediation/clean-up water supply sources Quantities of materials in inaccessible areas Used to estimate quantities of potential mold contamination on building materials or surfaces

9. Understanding Building Systems: Electrical Plans Based on floor, power & lighting plans Includes Notes, schedules & details Calculations for load requirements Location of panels, switches, receptacles, etc. ID’s paper insulation, cable wrap & cementitious panels ID’s temporary electric service needs

10. Understanding Building Systems: Contract Documents Specifications Work Drawings As built drawings Addenda Shop drawings Change Orders Submittals
