Analysis of the construction process of masonry in ceramic blocks from the perspective of lean construction

The construction industry has historically been seen as a sector permeated by numerous deficiencies within its production process. In order to mitigate this problem, we have the philosophy of Lean Construction (LC), where the progress of the construction sector can only be achieved through the continuous identification and elimination of activities that do not add value. The present study analyzes the influence of one of LC concepts, the principle of increasing transparency, on the performance of the constructive step of executing seals on ceramic blocks. A case study was carried out in a residential building, where the degree of knowledge of the employees regarding the activities they perform and the executive methodology used for the execution of masonry in ceramic blocks was analyzed, highlighting the impacts caused by the existence or the lack of techniques for increasing transparency. Through the case study, it was concluded that the low level of transparency of the case-unit promoted a work environment with scarce information flow, causing a production process without standardization, with a high level of uncertainties and with countless wastes.
