The paper presents a preliminary study of the labour consumption of the walls made of large-size calcium
silicate masonry units. The aim of the study was to verify how long the wall erection lasts, which is made
from five times larger elements than the standard used blocks and bricked with a mini-crane. Pilot studies
were carried out using two methods – summary and analytical-research. The test results were referenced to
existing normative. The article proposes to simplify the calculation formula, which is used to determine the
labour input for bricklaying walls in the described technology.
