Foundation plans
Foundation Plans

  • Details of construction for the footings and foundation walls

  • Footings and walls must be very carefully laid out, as the rest of the building relies on their accuracy

  • Slab-on-grade is a concrete slab poured directly on the subgrade (basement floors, main floors, garage floors, etc..)

Commercial framing
Commercial Framing

  • Framework constructed of structural steel and/or reinforced concrete.

  • Framework is designed to transfer loads to columns of steel, thus eliminating the need for load bearing walls.

  • Two types of floor and roof framing systems.

    • One-way floor system (Girders run parallel to each other)

    • Two-way floor system (Beams and girders run in both directions)

Commercial framing con t
Commercial Framing (con’t)

  • Steel Beam and Column Designations

    • W20x48

      • Standard Wide Flange (W) Shape

      • 20” nominal depth

      • 48 lbs. per linear foot

  • Open web joists are used in commercial and industrial construction.

    • Support loads more efficiently than beams and are more economical.

  • Designation:

    • 60DLH15

      • D: Deep; L: Long-span; H: High Strength

      • 60: 60” depth; 15: indicates range of span from 70’ to 120’, from a load table.

Residential framing
Residential Framing

  • Similar to commercial framing

    • Beams and joists used to support floors

  • Wood members used instead of structural steel and concrete.

  • More members used in residential frames (weaker material and no large columns.)

  • Weight of floor supported by wall instead of columns.

Wood framing
Wood Framing

  • widely-used, widely-known

  • affordable

  • durable

  • dependable

  • flexible construction methods


  • for exterior walls

    • given to outside of stud

  • for interior

    • given to edge of stud or

    • centerline of stud

      check drawing carefully to verify the dimensioning practice followed for any given set of plans
