A growing problem in the construction industry are project delays and their costs. The lack of Production Planning and Control (PPC) is one of the reasons of this problem. A stage of PCP based on the Lean philosophy principles consists in performing a previous analysis of constraints as a way of reducing uncertainly degree, work delay and costs generated by these. The Last Planner System™ (LPS™) confirms the importance of this analysis and is increasingly being applied to projects that have a solid construction planning sector. This research describes constraints constructive processes in stages of construction buildings from the civil engineers perceptions. This research has a qualitative character and a descriptive nature. It was identified that constraints have different origins and relate primarily to: processes, manpower, designs, materials, machinery and equipment, suppliers, fluxes, productivity, management, planning, technological innovations, motivational issues, climatic conditions, among others observed during the survey. These constraints are observed by most engineers, however, constraints are not used in a formal planning and management. Additionally, there are difficulties in the implementation of new management concepts and management tools because of an existent cultural paradigm.
