CARA PENGIRAAN BATA :

1 IKATAN STRETCHER / DATAR BATA (Tebal 1 Bata) :
Cari keluasan tembok iaitu = Panjang x tinggi tembok
Panjang 5m dan tinggi 3m = 5 m x 3 m = 15m²
= 15 m x 60 biji/ketul ( 1 m² = 60 biji bata - Stretcher )
Jumlah bata = 900 ketul Mortar ( Bancuhan 1 : 4)
Ada dua kaedah pengiraan mortar iaitu :
1) Berpandukan bil. bata = 900 ketul x 0.5/1000 = 0.45 m³
2) Berpandukan luas tembok = 15 m² x 0.03 = 0.45 m³
Simen = 1/5 x 0.45m³ = 0.09 m³ Dalam kiraan beg/kampit
= 0.09 m³ x 28.25 bag/kampit = 2.5 bag Pasir
= 4/5 x 0.45 m³ = 0.36 m³

IKATAN STRETCHER / SISI BATA (Tebal 1/2 Bata) :
Formula Pengiraan Bata : Cari keluasan tembok iaitu
= Panjang tembok x tinggi tembok
Contoh 2. Ikatan English ( lihat Rajah B)
= Panjang 5m dan tinggi 3m = 5 m x 3 m = 15m²
= 15 m x 120 biji/ketul ( 1 m² bersamaan 120 biji bata untuk ikatan 1 bata tebal)
Jumlah bata = 1800 ketul

Mortar ( Bancuhan 1 : 4)

Ada dua kaedah pengiraan mortar iaitu :
1) Berpandukan bil. bata = 1800 ketul x 0.5/1000 = 0.90m³
2) Berpandukan keluasan tembok = 15 m² x 0.06 = 0.90m³
Simen = 1/5 x 0.90m³ = 0.18 m³
Dalam kiraan beg/kampit = 0.18 m³ x 28.25 bag/kampit = 5 bag Pasir = 4/5 x 0.90 m³ = 0.72 m³

FORMULA KERJA-KERJA MELEPA (PLASTER) :

Panjang x Lebar 25 m x 3 m = 75 m²
Ketebalan lepaan adalah 19 mm = 75 m² x 0.019 m
Jumlah Mortar = 1.43 M³
Jumlah Simen = 1.43 M³ x 1/5 = 0.286 M³
Kiraan dalam beg/kampit 0.286 x 28.25 = 8 beg simen
Jumlah Pasir = 1.43 m³ x 4/5 = 1.14m³

FORMULA PENGIRAAN JUBIN / MOZEK :

LUAS KAWASAN LUAS ÷ JUBIN
Contoh 1: Jika saiz jubin 300 mm x 300 mm Luas Kawasan = panjang x lebar = 25 m x 3 m = 75 M²
Luas Jubin = 300mm x 300mm
= 0.300 m x 0.300 m = 0.09 m²
Bilangan Jubin = 75 m² ÷ 0.09 m² = 834 keping

FORMULA KIRAAN MORTAR PELEKAT (MORTAR BED) :
Panjang x Lebar 25 m x 3 m = 75 m²
Ketebalan mortar 20 mm = 75 m² x 0.0003.
Jumlah Mortar = 1.5 M³
Jumlah Simen = 1.5 M³ x 1/5 = 0.30 M³
Kiraan dalam beg/kampit = 0.30x 28.25 = 8.5 beg simen
Jumlah Pasir = 1.5 m³ x 4/5 = 1.2 m³

KIRAAN PELEKAT ADHESIVE FORMULA :
Panjang x Lebar = 25 m x 3 m = 75 m²
Ketebalan adhesive 5 mm = 75 m² x 0.005m
Jumlah Mortar = 0.37 M³

FORMULA PENGIRAAN ISIPADU KONKRIT :

= Panjang x Lebar x Tinggi = 15 m x 5 m x 1 m
Isipadu konkrit = 75 m³ ( Nisbah Bancuhan 1:2:4 )
Jumlah simen = 1/7 x 75 m³ = 10.72 m³
Kiraan Dalam Beg/Kampit = 10.72 x 28.25 beg
= 303 bag/kampit
Jumlah Pasir = 2/7 x 75 m³ = 21.43 m³
Jumlah Batu = 2/7 x 75 m³ = 42.86 m³

FORMULA PENGIRAAN ATAP

Luas kawasan ÷ Luas Atap = Bilangan Atap (keping) Contoh Pengiraan:
Luas Kawasan = 15m x 5m = 75 m²
= 75 m² bersamaan 807 k²
Bilangan Atap = 807 k ² ÷1 k² = 807 keping
Nota: Anggaran Pingiraan a) 1m3 simen = 28.25/bag b) 1 m² bersamaan 10.76 k²)

FORMULA PENGIRAAN SILING :

Keluasan siling rumah ditentukan oleh horizontal. Jika sama timbangan air boleh terus gunakan formula begini.
Kira luas sekeping siling.
Contoh 0.6 m x 1.2 m = keluasan sekeping siling
Jadi keluasan = nilai x darab nilai y.
Jumlah tersebut bahagi dengan keluasan sekeping siling . Dapat jumlah keping yang akan digunakan.

FORMULA PENGIRAAN CAT :

CAT AIR (dinding bersimen)
Kira dahulu keluasan yang akan di cat.
Formula cat adalah 1 liter cat boleh meliputi dinding seluas 15 meter persegi (untuk 1 lapisan)
1 liter = 15m2. Jadi keluasan keseluruhan bahagi dengan 15m2 kita akan mendapat jumlah liter cat yang akan digunakan. Pengiraan ini adalah untuk 1 lapisan yang dicat sahaja.

CAT MINYAK (Besi / kayu / zink)
Formula yang digunakan adalah 1 liter cat boleh meliputi dinding seluas 18m2.
1 liter = 18m2

Pengiraan untuk cat diatas adalah untuk permukaan yang telah disapu dengan cat alas (undercoat) pengiraan untuk undercoat adalah 1 liter cat bersamaan 20m2.
