Definition and Purpose A plot plan is a plan view drawing which
show the site and location of the building on the property.
Slide 3
Definition and Purpose Plot plan shows: Page 154
Slide 4
Property Lines Property lines define the site boundaries The
length and bearing of each line must be identified on the plot plan
Measured with an engineers scale to 1/100 Bearing angles are
recorded in degrees and minutes (seconds) S 63 W
Slide 5
Property Lines Property Corners Identified with a special
symbol Benchmark Where the property corner begins and ends
Slide 6
Contour Lines A contour is a line connecting points which have
the same elevation. Contour lines help to describe the topography
of the site by depicting shape and elevation of the land. Survey
uses a mean sea level. Home construction - relative elevations are
sufficient.
Slide 7
Contour Lines Page 156
Slide 8
Topographical Features Represented by symbols non standard
symbols should appear in the legend of the drawing Topographical
Drawing Color Black - lettering the works of man (roads, houses)
Brown - land forms (contour lines) Blue - water features (lake,
stream, marsh) Green - vegetation (trees)
Slide 9
Location of Structure on Site Analyze site to determine best
location of house on site contour trees view surrounding houses
code restrictions Style of house Solar orientation Winds Placement
of septic
Slide 10
Location of Structure on Site Three methods of drawing house on
site 1. Lay out the outside of the exterior walls omitting all
interior walls and roof. Shade or crosshatch space covered by
house
Slide 11
Location of Structure on Site Three methods of drawing house on
site 2. Draw the exterior walls as hidden lines with the roof shown
as solid lines
Slide 12
Location of Structure on Site Three methods of drawing house on
site 3. Show all exterior wall thickened with all interior walls,
windows and doors omitted * House must be dimensioned on all three
types of drawings

Procedure for Drawing Plot Plan Page 160
Slide 14
Landscape Plot Plans Designed to show the type and placement of
trees, shrubs, flowers, gardens and pools on the site Plans the
total setting for the home Symbols are used to represent various
types of trees and plants.
Slide 15
Footings, Foundations and Conrete Chapter 9
Slide 16
Footings, Foundations & Concrete Staking out house location
1. Locate each corner of the house by laying off the distances
indicated on the plot plan. 2. The position of all corners should
be checked for accuracy by diagonal measurement. 3. A control point
is needed to determine the depth of excavation and foundation wall
height.
Slide 17
Excavation For footings and foundations the top soil is usually
removed and saved for final grading. Excavation of footings should
extend a minimum of 6 inches, into undisturbed earth. Excavation of
footings must also be extend down to a minimum of 6 inches below
the average maximum frost penetration depth.
Slide 18
Excavation Remove the top soil. Excavation must be below frost
line for footing Excavation must be large enough for work space and
foundation drains.
Slide 19
Footings Increase the support capacity of the foundation wall
by spreading the load over a large area. Footing thickness is equal
to the foundation wall thickness and footing width is twice the
wall thickness.
Slide 20
Foundation Walls T- is the most common type of foundation. Slab
foundation is an extension of a slab floor. Pier and Post
foundations serve as an auxiliary foundation to support long
spans.
Slide 21
Basement Walls Basement walls are controlled by local building
codes. Beams and girders are used to support floor joist. Lintels
are a horizontal structural member that supports the load over an
opening such as a door or a window.
Slide 22
Concrete Concrete is a result of combiningcement, sand,
aggregate and water. Cement is composed of a mixture of lime,
silica, alumina, iron components
Slide 23
The Foundation Plan Chapter 10
Slide 24
The Foundation Plan Definition and Purpose plan view drawing in
section which shows the location and size of footings, piers
columns, foundation walls, and supporting beams.
Slide 25
The Foundation Plan Includes: Footings for foundation walls,
piers, columns Foundation walls Piers and columns Dwarf Walls
Partition walls, doors and bath fixtures Openings in foundation
wall such as windows, doors and vents
Slide 26
The Foundation Plan Includes: Beams and pilasters Direction,
size and spacing of floor joists Drains, sump Details of foundation
and footing construction Complete dimensions and notes Scale of
drawing
Slide 27
The Foundation Plan Purpose The foundation plan is prepared
primarily for the excavator, masons and cement workers who build
the foundation
Slide 28
The Foundation Plan Preliminary steps to drawing a foundation
plan examine the floor plan to determine the type of exterior walls
examine plot plan to anticipate the need for stepped footings and
retaining walls Determine the size of footings and foundation walls
required from information available.
Slide 29
Drawing The Foundation Plan 1. Select Scale 2. Locate outline
on paper 3. Draw the foundation walls, piers, and columns and
foundation for chimney 4. Indicate breaks in found. Wall for
windows, doors, etc 5. Layout and draw footings (Hidden)
Slide 30
Drawing The Foundation Plan 6. Draw footings for piers 7. Draw
footings for fireplace and chimney 8. Locate the supporting beam 9.
Show size, spacing and direction of the floor joists. 10. Identify
the location of sections 11. Draw necessary sections and
dimensions
Slide 31
Drawing The Foundation Plan 12. Determine the location of
dimensions needed to show the size of all aspects of the foundation
13. Draw the dimensions and dim. lines 14. Letter and notes 15.
Shade the foundation wall drawing with proper symbols.
Slide 32
Drawing The Foundation Plan 16. Add the title block, scale and
name of drawing in the proper location 17. Check drawing to be sure
you have included all necessary info.
Slide 33
The Basement/Foundation Plan Basements are usually included in
cold climates. Cheaper to build. The basement plan is a combination
floor and foundation plan Includes information commonly shown on
the foundation plan and at the same time show interior walls,
stairs, windows and doors.
Slide 34
Procedures For Drawing a Basement Plan 1. Select Scale 2. Draw
the foundation walls, piers, and columns and foundation for chimney
3. Draw footings for foundation 4. Locate and draw the beam and
supports or bearings wall partition 5. Design room layout in
basement area and darken in the lines
Slide 35
Procedures For Drawing a Basement Plan 6. Indicate breaks in
basement walls 7. Locate and draw stairs 8. Show size, spacing and
direction fo floor joists 9. Identify the location of sections 10.
Draw necessary sections 11. Locate and draw bath fixtures, furnace,
hot water heater, etc.
Slide 36
Procedures For Drawing a Basement Plan 12. Determine the
location of dimensions 13. Dimension 14. Letter any notes 15. Show
electrical switches, outlets and fixtures 16. Shade the foundation
walls with symbols
