Points to Remember for Civil Site Engineer

Following are some general points

‌Chair spacing maximum spacing is 1.00 m (or) 1 no. per 1m2 ‌For dowels rod minimum of 12 mm diameter should be used. ‌Chairs minimum of 12 mm diameter bars to be used ‌Longitudinal reinforcement not less than 0.8% and more than 6% of gross c/s

Density of Materials Materials                          Density Bricks                             1600-1920 kg/m3 Concrete Block                   1920 kg/m3 Reinforced Concrete            2310 - 2700 kg/m3

Slump Value (IS - 456)

Lightly Reinforced Concreate    25-75 mm Heavily Reinforced Concreate     75-100 mm Trench fill 100-150 mm (for in-situ & Tremble)

CUBE SAMPLES

1-5 m3 - 1 no. 6-15 m3 - 2 no. 16 - 30 m3 - 3 no, 31 - 50 m3 - 4 no. Above 50 m3 - 4+1 mo. of addition for 50 m3

GRADE OF CONCRETE

M5   -     1:4:8 M10 -      1:3:6 M15 -      1:2:4 M20 -     1:1.5:3 M25 -      1:1:2 M30 -      Design Mix

CLEAR COVER TO MAIN REINFORCEMENT

Footing   -     50 mm Raft Foundation (top) - 50 mm Raft Foundation (Bottom) - 75 mm Raft Foundation (side)    -  75 mm Beam  - 25 mm Strap Beam - 50 mm Column - 40 mm Slab - 15 mm Flat Slab - 20 mm Staircase - 20 mm Retaining Wall    -     20-25 mm Water Retaining Wall    -    20-30 mm

Nepal Length using Land

1 angul = approx. 0.75 inch 4 angul = 1 dharnugrah (bow grip) = 3 in 8 angul = 1 dhanurmushti (fist with thumb raised) = 6 in 12 angul = 1 vitastaa (span) = 9 in 2 vittaa (cubit) = 18 in 1 haath = 1.5 ft. 1 dand or dhanush (bow) = 4 haath = 6 ft 2000 dand = 1 kos or Gorut = 4000 yards or 2.25 miles 4 kosh = 1 yojan = 9 miles = 14.48 km

Area

1 Khetmuri = 25 Ropani 1 Bigha = 20 Kattha = 6772.63 m² = 72900 sq.ft. = 13.31 Ropani 1 Katha = 20 Dhur = 338.63 m² = 3645 sq.ft. 1 Dhur = 16.93 m² = 182.25 sq.ft. 1 Ropani = 16 Aana = 64 Paisa  = 508.72 m² = 5476 sq.ft. = 256 Daam = 4 llka 1 Aana = 4 Paisa = 31.80 m² = 342.25 sq. ft. = 16 Daam 1 Paisa = 4 Daam  = 7.95 m² = 85.56 sq. ft. 1 Daam = 1.99 m² = 21.39 sq. ft.    1 Khetmuri = 25 Ropani 1 Bigha = 20 Kattha  = 6772.63 m² = 72900 sq.ft. = 13.31 Ropani 1 Katha = 20 Dhur  = 338.63 m² = 3645 sq.ft. 1 Dhur = 16.93 m² = 182.25 sq.ft. 1 Ropani = 16 Aana  = 64 Paisa  = 508.72 m² = 5476 sq.ft. = 256 Daam = 4 llka 1 Aana = 4 Paisa = 31.80 m² = 342.25 sq. ft. = 16 Daam 1 Paisa = 4 Daam = 7.95 m² = 85.56 sq. ft. 1 Daam = 1.99 m² = 21.39 sq. ft.

'''Terae Region '''

the Terai region, the southern parts of Nepal, the customary units are those used elsewhere in South Asia:

1 Katha = 20 dhur 1 bigha = 20 katha

Hilly and mountainous regions

A different system is used in hilly regions:

1 paisa = 4 dam (daam) 1 ana = 4 paisa 1 ropani = 16 ana

Conversions

1 ropani = 74 feet × 74 feet 1 bigha = 13 ropani 1 kattha = 442 square yards or 338 square meters
