There are ____ concrete hollow blocks per square meter of wall area.
13 CHB
Estimate the number of hollow blocks required for the portion of a wall of a farm workshop which is 3.5 meters high
from the finished floor line and 20 meters long (excluding columns and beams). From the finished floor line the wall is extended 0.6 meters lower for the wall footing. Add a contingency of 10%
A= 20(3.5 + 0.6) = 82 m²
N = 82 m² x 13 CHB/m²
= 1066 CHB
@ 10% contingency
N = 1066 x 1.1
Answer:
N = 1173 CHB pcs
