Identification of extra-planning activities in structural masonry construction process: case study and interview with managers

Abstract

The present study examined the issues of fault identification in the production of buildings in masonry and searched actions (good practices) that add value to the built product, called hair of extra-planning activities. These activities when inserted into the production system prevent or minimize interruptions of work. They may be incorporated into the process or help you. The objective of the research was to identify extra-planning activities in the construction process of structural masonry elevation and investigate its recognition by managers. It was made a connection between the Lean Construction and the daily practice in the studied site. The methodology included literature review and case study. The study presented goals with descriptive characteristics and was based on an activity integration model. It was chosen a project to research and to data collection. Unstructured interviews with the technical team of the work were carried out. It also used other tools such as photographic records; consulting projects and development of physical flows (flow chart). As a result, it was possible to distinguish extra-planning activities and failures in the analyzed site. The main good practices and failures identified using the method were linked to inputs, classifying the flow and materials management as strategic points on the site. The study contributes to the spread of lean ideas in construction, from the proposition of activities that provide increased rationality.
