In construction:  Finishes take longer to install  Are more expensive than other tasks  Room can be basic or more elegant In life:  Women typically want the best of the best  AND……

 Nonbearing wall  Consists of light-gage steel studs in a C-shaped runner at the top and bottom of partition  Main use is to form stud walls  Used in commercial building; whereas, timber studs used in residential

Solution steps: Determine the total number of studs need, assume standard spacing Then determine number of pieces of runners

 Consists of the gypsum board, metal or plastic trim, fasteners, tape, and drywall compound  Boards come in different thicknesses but typically 1/2 and 5/8 inches  Width is always 4 feet Length varies from 8 to 16 feet  Different types  Standard- typically used  Type X (fire rated)- used to create fire rated partitions and ceilings  Water resistant- used in wet areas (bathrooms, laundry rooms, etc.)

 Known as Drywall or Sheetrock  Sheets 1/2” or 5/8” thick and 4 ft wide by 8 or 10 ft long.  Fastened to furring strips on concrete walls, directly to studs, and to the ceiling joists.  Labor hours required to install drywall varies with size and complexity of area. (round walls are more complex than flat walls)

 Priced by the square ft  Taping and finishing are listed by sq ft  Pricing depends on finishing:  Textured, smooth, sprayed  Hanging drywall is usually done by a crew  Usually a budget is allotted for touch-ups

 Prefinished plywood panels are used to cover walls and ceilings.  Panels are ¼” – ¾” thick; 4’ X 8’  Available in almost any material.  Cost depends on size and species.  The cost of labor installing plywood panels varies considerably with size, shape, and complexity of area.  Waste factor can be high depending on shapes in areas.

 Base board moldings are made of pine or oak  Installed at floor level around the room.  Crown molding are installed at ceiling level

 VCTs have no space between titles  Eliminates need for grout  Available in 12 in x 12 in squares  Glue needs to be calculated from historical data  Affordable, durable, and strong  Typically used in commercial and industrial buildings such as schools

 Roles or pieces  Bid as a linear good  Can be bent around corners, no cutting required  Cheaper than wood baseboard  Typically used in commercial buildings such as schools and hospitals

 Pad is sheet good  Fastening strips are required  Trim is required anytime the carpet transitions  Fastening strips and trim are bid as a linear good

 Bid on the square footage; roll or spray  Trim paint must be specified; brushed on  Specify number of coats  Can turn a basic room to an elegant room
