Process engineering applied to building projects has not developed its own methodology for project management, so it has been using generic project management tools, based on PERT and GANTT, under the paradigms Critical Path Method or Critical Chain. Both PERT and GANTT do not consider some variables that are relevant in the specific environment of a construction site, such as: location, repetitive activities, productivity, continuity of work for external crews, material transformation, space clashes, etc. This article analyzes: 1) The theoretical foundations of generic project management tools based on activities management, 2) The significant variables in both production and project management paradigms, 3) The new paradigm and conceptual tools developed over the last 20 years in the Lean Construction community of knowledge. The findings of this research will help construction managers and superintendents, explaining why the standard tools they are using are not enough to manage their regular work, and proposing a more adequate set of tools and systems to plan and control production activities on site. |
