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
