TYPES OF WOOD |
|
|
Teak Wood |
Very expensive - Used for
Doorsfor doorsand windows |
|
Sal-wood |
Economical- Used for Door Frames |
|
Flush wood |
Cheaper- Used for Door Shutters |
|
Plywood |
Economical
Used for Wardrobes, Shelves and Cup-board |
|
Nova pan |
Cheaper-
used for Tables and Chairs [ with dust partials of wood] |
|
Rubberwood |
Cheaper-
but not recommended, as it has expanded and contraction
due to weather conditions |
In the old days, measuring the amount/quantity of wood needed to make doors and windows, they would buy wood from the market and allow the carpenter to build doors and windows on the site. Doors and windows are now readily / readymade available to save time and manpower.

Problem
-1:
Find
Cost of Doors, of Size 3'6" x 7' along with Door shutter and Door frame
if,
No.
Of Doors = 6
Section
Of Door Frame = 4” x 3”
Door frame/Rate = 1800 Rs/cft
(exotic wood – rate differ accrding to wood quality)
Door
shutter Rate/sqft = 120.0 rupees
Solution:
1. Door Frames:
Given
rate for each Door frame of size 3'6" x 7' (3.5’ x7’) with section of
frame 4” x 3” = 1800 rupees per cft
No.
of Door frames = 6
Length
of the frame = 7′ (2 side.)+3.5′ (1 members in top) = 17.5 rft
The
total length frame = 6 nos (number of doors) x 17.5 rft = 105 rft
The cross-section is 4” x 3” is being used for this size of 7′×3′ 6”. With a 4″×3″ section,
Volume of wood required= 105′× 4/12′×3/12′=
8.75 CFT.
Cost for Door frames = 1800 x 8.75 = 15750/-
2. Door Shutters:
Given
size of Door = 3'6" x 7'
To
have the actual length and height of the door we want to deduct the frame (4”x3” – 3” will
be the width) from the size of the door so,
Length
of Door shutter = 3’6" - 3" - 3" = 3’
Height
of Door Shutter = 7’ - 3" = 6’9"
Size of Door = 3' x 6'9”
Note: the size of the door should be
2” to 3” excess for jambs (side and head jambs). Carpenter will cut the
shutter according to the measurement of frame-to-frame.
Size of Door shutter area = L x H = 3' x 6'9” = 20.25sqft
For
Door Shutter given rate / sqft = 120.0 rupees
No.
of Shutters = 6
Cost for Door Shutters = 120.0 x
20.25 x 6 = 14580/- rupees
Total cost for 6 Door Frames & Door Shutters = 15750 + 14580
= 28,965/-
Door shutters will be selling in terms
of area and per door
Problem
-2:
Find
Cost of Windows, of Size 4' x 4' along with Window shutter and Window frame if,
No.
of Windows = 5
Section
of window frame = 3"x 3"
Window
frame/Rate = 1800 Rs/cft (exotic wood – rate differ according to wood quality)
Window
Shutter = 1200.0 rupees
Solution:
1. Window Frames:
Given rate for each Window
frame of size 4' x 4' with a section of frame 3"x 3"= 1800 Rs/cft (exotic
wood – rate differ according to wood quality)
Length
of the frame = 4′ (3 side.)+ 4′ (2 members in top and bottom) = 20 rft
The
total length frame = 5 nos (number of frames) x 20 rft = 100 rft
The cross-section is 3” x 3” is being used for this size of 4′×4’. With a 3″×3″ section,
Volume of wood required= 100′× 3/12′×3/12′=
6.25 CFT.
Door
frame/Rate = 1800 Rs/cft
Cost for window frames = 1800 x 6.25 = 11250/-
2. Window Shutters:
Size
of each window shutter = 4' x 4'
To
have the actual length and height of the window we want to deduct frame (3”x3” – 3”
will be the width) from the size of the window so,
Length
of Window shutter = 4’ - 3" - 3" - 3" = 3’ 3"
Height of Door Shutter = 4’ - 3"- 3" = 3’6"
Note: the size of the door should be
2” to 3” excess for jambs (side and head jambs). Carpenter will cut the shutter
according to the measurement of frame-to-frame.
Providing
two shutter panels = 3’ 3"/2 in each window = 1’ 7 1/2"
Size of each window shutter = 1’ 7
1/2" x 3’6"
Given
Rate/each window shutter = 1200.0
No.
of Shutters = 2 in each widow
No.
of Windows = 5
Cost for Window Shutters = 1200 x 2 x 5 = 12000/- rupees
Total cost for 5 Window Frames & Window Shutters = 11250 + 12000
= 23,250/-
Window shutters will be selling in terms of area and per
Shutter
