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