The line of balance (LOB) is widely used for projects with repetitive batches. Nevertheless, some authors in academic literature recommend the LOB for nonrepetitive areas. In the case of residential projects which have a high repetition of the same batch the LOB is a very useful tool to plan the construction. In the other hand, developing a LOB for common areas (pavements without repetitive areas and services, e.g. underground floors, leisure areas, guardhouse and mezzanine) where there is not repetitive batches is more difficulty, and this is the reason for its scarce use for common areas. Thus, major problems in the project are verified by the lack of planning and production control in common areas. This article aims to formulate guidelines for developing a LOB for common areas through a case study at a Brazilian construction company. The methodology for developing this paper includes literature review on LOB in non-repetitive areas, characterization of the company and construction sites, development of a common areas plan using LOB and other auxiliary tools, analysis of results and formulation of guidelines for the development of a LOB for common areas. The results of this study indicated that the LOB in common areas provided plan transparency to employees and engineers, improved the control of project’s total term and decreased the allocation of workers teams.
