Objectives• Design and draw a foundation plan for a typical

residential structure using traditional or CADD methods.

• Design and draw a basement plan for a typical residential structure using traditional or CADD methods.


Foundation Plan• Foundation plan

– Plan view drawing in section

– Location and size of footings, piers, columns, foundation walls, beams, pilasters

– Usually drawn after the floor plan and elevations have been roughed out

Foundation Plan• Symbols, hatch patterns used to represent

materials



Basement Plan• Basements

– Popular where frost penetration is several feet deep

– Provide usable space at less cost

• Basement plan– Combination foundation and floor plan

– Required for a split-level house

Preparing to Draw a Foundation or Basement Plan• Study information on the preliminary floor plan, site

plan, and elevations

• Use the floor plan as an underlay

• Determine type and size of exterior walls– Stud wall frame

– Stud wall with brick veneer and brick ledge


Preparing to Draw a Foundation or Basement Plan

• A brick veneer house needs foundation wall 8 inches longer and wider than foundation wall for frame structure



Preparing to Draw a Foundation or Basement Plan• Examine elevations and site plan

– Need for stepped footings or retaining walls

• Determine size of footings and foundation

• Check soil bearing capacity

• Refer to local building codes

Soil Bearing Test• Soil bearing test determines load-bearing capacity

of the soil

Traditional Drawing Techniques• Steps for drawing a foundation plan and a

basement plan are similar– More information and additional steps are required

for a basement plan


Manual Drafting:Foundation Plan

2. Locate outline of foundation walls

3. Draw foundation walls, piers, and pilasters

4. Indicate breaks in foundation wall

5. Lay out and draw wall footings

Manual Drafting: Foundation Plan

• A partially completed foundation plan shows the foundation walls, piers, pilasters, and vent openings




6. Draw footings for piers and columns (posts)

7. Draw footings for fireplace and chimney

8. Locate and draw supporting beam (if required)

9. Show size, spacing, and direction of joists or trusses

10.Identify location of section details



• Footings for foundation walls and piers, supporting beam, all section symbols, and floor joist data have been added to foundation plan

Partially Completed Basement Plan



CADD Drawing Techniques• Drawing is created at full scale, 1'- 0" = 1'- 0", or 1:1

• Appropriate scale is applied when drawing is plotted


CADD: Foundation or Basement Plan

1. Make copy of floor plan on new layer

2. Draw outside line of foundation walls, delete outside line of floor plan wall if they do not coincide

3. Draw all footings

4. Draw stairs, interior walls, windows, doors for basement plan

6. Dimension plan

7. Insert symbols for appliances, fixtures, and furnace

8. Add cutting-plane symbols where required



9. Label room name and sizes

10.Add scale and title to foundation plan layer

11.Look over plan for completeness



• The interior walls, stairs, windows, and doors

Parametric Modeling: Creating a Foundation or Basement Plan

1. Draw foundation walls using WALL command

2. Create the foundation wall footings

3. Draw the structural slab representing the basement floor using FLOOR command

4. Use COLUMN command to create columns and footings supporting the columns



5. Create the supporting beam above the columns using BEAM command

6. Draw the interior walls of basement

7. Dimension the plan

8. Add cutting-plane symbols where required to indicate sections
