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
