Dimensioning
Plumbing Plans
HVAC Plans
Electrical Plans/Wiring Diagrams
Masonry Symbols
Welding Symbols

4. 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..)

10. 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)

11. Commercial Framing (con’t)
Steel Beam and Column Designations
W20x48
Standard Wide Flange (W) Shape
20” nominal depth
48 lbs. per linear foot

13. Reinforced Concrete floor systems - one way
Girder (resting on column)
Concrete beam

14. Reinforced Concrete floor systems - two way waffle
Waffle Pan or dome system

15. Commercial Framing (con’t)
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.

16. 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.

17. Wood Framing widely-used, widely-known affordable durable dependable
flexible construction methods

18. Dimensioning for exterior walls for interior
