Understanding Building Systems

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

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
