CHAPTER 11FINISHES
CON 4003 Construction Estimating
Prof R. V. Locurcio
What are finishes?
Include Nonbearing walls Finishes applied to floors,
walls, and ceilings
Why are finishes important?
In construction: Finishes take longer to install Are more expensive than other tasks Room can be basic or more elegantIn life: Women typically want the best of the
best AND……
Metal stud partitions 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
Example 11-1
Solution steps:Determine the total number of studs need, assume standard spacingThen determine number of pieces of runners
Example 11-1 continued
Gypsum board
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.)
Wood Furring Strips Placed on masonry and
concrete walls to permit installation of gypsum, prefinished plywood, or other type of finished interior wall materials.
Labor Hours required to place wood furring strips and grounds in usually estimated by 100 lf.
Gypsum Wallboards
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)
Drywall
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
Wall Paneling
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.
Interior Trim Moldings
Base board moldings are made of pine or oak
Installed at floor level around the room.
Crown molding are installed at ceiling level
Example 11-2
Example 11-2 continued
Suspended Acoustical Ceiling
Consists of ceiling tiles suspended from the ceiling in a metal grid
Grid consists of wall molding, main tees, 4 foot cross tees, and 2 foot cross tees
Quick installation of lights and AC vents
Metal studs do not go to the top of the ceiling
Freedom of where to run the ducts
Example 11-4
Example 11-4 cont’d
Laminate Floors
Floats over concrete which allows floors to move, expand, and contract
A gap is left between all edges of the floor
Vapor barriers, sound-deadening underlayment, and trim must be included in cost
Wood Flooring
Example 11-5
Example 11-5 continued
Sheet Vinyl More durable than linoleum
Typically used in high volume areas and in bathrooms
Cheaper version of wood and laminate
Available in 12 foot widths
Must be installed in one direction
Rooms wider than 12 feet, pattern must be seamed
Comes with glue on it, just have to rip off plastic
Vinyl Composite Title 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
Rubber Base 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
Carpet and pad 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
Carpet Installation
Paint 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
