project definition
Project Definition
  • Design layout of a 1-story house
  • Two twelve person independent design project
  • Twelve week design period
  • Paper Design (DCAD) and Computer-Controlled Scaled Model of the house

*Extra Credit: A 3D model done on Design Cad

house design specifications
House Design Specifications
  • AREA:
    • 2500 sq. ft. max (for the house only)
    • Plot of land will be decided by the group
  • OTHER:
    • Floor Area to External Opening Area must at least have a ratio10% (i.e. glass windows, and glass doors)
    • At least one form of secondary egress
    • House Foundation is free
  • BUDGET: $60,000 max

NOTE: If a garage is required:

- extra 200 sq. ft. and $2000 are allotted

general construction
General Construction
  • Floor and ceiling joists run the length of the house and are placed 2.5’ apart o.c. (on center)
  • Beams run from floor to ceiling and are place 1.33’ apart o.c.

Refer to reference section for glossary of construction terms p.102

general construction1
General Construction

Beams: run from floor to ceiling

1.33’ on center

2.5’ on center


run the length of the house

general construction2
General Construction
  • Dimensions given as
    • width * length, or
    • width * height, or
    • width * depth * length
  • Dimension in engineering format

(e.g.: 1.50 feet is a SET PRECISION OF 2 DECIMAL Points)

structural construction
Structural Construction
  • Walls
    • Outer walls - 0.5 feet thick (6 inches)
      • Brick wall  No plywood but insulation & studs
      • Shingles  Plywood and tarpaper needed
    • Inner walls - 0.3 feet thick (4 inches)
structural construction1
Structural Construction
  • Doors
    • Outer doors – 4.0 feet wide
    • Inner doors – 3.0 feet wide (3 inches)
  • Windows are 2.5 feet wide (minimum)*
    • Any window can be used if less than 5.0 feet (i.e. double hung)
    • More than 5.0 feet must be picture window

*Standard size, windows may be bigger

structural construction2
Structural Construction
  • Plywood placed on
    • floor
    • ceiling
    • outer walls
  • Sheetrock placed on
    • All walls, inside and outside
    • Inner walls need sheetrock on both sides.
  • Roof
    • assume flat for cost estimate
    • angle/slope for aesthetic
      • Must be 5 degrees to 15 degrees elevation
  • Main lines (cold and sewage) enter from the front of house
  • Hot and cold water pipes must run under the house
  • Sewage pipes must run outside the house
  • Only one sewage line can enter a room at one time
  • Piping placed the shortest distance from the fixture to the front of the house
  • Must turn at right angles
  • Three types of pipes, create legend to identify each:
    • cold water = 0.16 feet blue centered line
    • hot water = 0.16 feet red centered line
    • sewage = 0.5 feet black solid line
  • Symbol must be placed perpendicular to a wall
  • Must indicate location of:

220 Volts Lights


Switches 110 Volts

  • Switches must be connected to the light with a beveled dashed line


  • Outlets must be perpendicular to the wall
  • Outlets must be placed roughly every 8 feet
  • 220 outlets should be placed in the utility room and the kitchen
    • Electric Stove
    • Hot water heater
    • Boiler
  • “General Construction” Costs:
    • Screws, nails, ceramic & vinyl tile, house’s foundation
    • Cost of labor for pouring concrete
    • Installation of electric fixtures and wiring, joists, beams, plywood, paneling, aluminum siding, brick, sheetrock, etc…….
    • See Appendix for prices
design cad drawings
  • Include what layer and what revision
  • Include information such as company name…
  • Scale the border 10 times on the x and y axis and paste it into its own layer
  • Floor plan must be scaled to 10 feet=1 inch
design cad drawings1
  • Layers
    • Main floor plan
      • Walls, doors, windows and plumbing fixtures (sinks, tubs, toilets, etc.)
      • Room labels
    • Plumbing(hot/cold water lines and sewage)
    • Electrical(switches, outlets, lights, etc.)
  • Font size
sample pricing





Sample Pricing

A SureTrak chart presented at each recitation

    • Indicate who is doing which activity
  • MILESTONE (8th week)
scaled model
Scaled Model


  • Foam Board
  • LED’s & Wires
  • Open Lab tools

*Extra materials will be at student’s expense.


scaled model1
Scaled Model


  • Scale: 4 feet = 1 inch (for length, height and width)
  • Maximum model of 1.09 sq. feet
