Companies of construction industry in Belem, they are looking for ways to improve their processes and constructive methods through the implementation of the elements and tools of lean production system. The purpose of this work consisted to assess the cases of successes and failure, through of an exploratory study of the implementation of the Lean Production System in construction sites in the city of Belem of Para, to identify which elements and tools of this system are most commonly used in construction of the city in question. This way, an extensive research literature about the subject, showing historical developments since the creation of scientific administration, emphasizing the precursors of production administration and then reporting the emergence of lean production system, as well as their origins and pillars, highlighting its elements and tools. The research methodology used was case study of exploratory character, where the focus was managers that act applying lean production in their construction works. The data was collected through a questionnaire with the classification of questions, closed and multiple choices, consisting of twenty objective questions, in order to generate data to answer the research question. After collecting data were generated tables and graphics for analysis of results. The results analyzed pointed elements and tools lean more used, in addition to presenting the greatest difficulties in the implementation of lean production system, and then was made a correlation between difficulties encountered with the relevant literature. From this, it was concluded that companies are not fully committed with the implementation of improvements (lean production system), so that this demotivates workers and creates resistance to change.

The stagnation of the economy in the country make each time more business to look for alternatives to improve their results. The difficulty in obtaining mortgage loans strongly influences the rise of the distractions of the houses and apartments purchased, creating more offers and consequently increasing the competition between builders, which forces them to give discounts, making the expected profit is less for their enterprises. On this scene of challenges, the construction companies have been searching for improve their managment and processes. A alternative to make it happen is the development of their own management system, encompassing all steps of the process, starting in the concept until the after construction. The searching strategy is the searching-action, it consists in diagnoses the problem, plans the solution actions, implement these actions, evaluate the results and find possibilities of new actions. On this type of searching, the searcher's focus is on provocate changes in the system, monitoring the results and at the same time increasing the kwoledge about the theme. To define the searching, were made trhee steps: 1) Understood, where were full-blown the starting studies of productivity, construction quality and Lean filosofy, later being developed and approved tools to be applied in construction processes, 2) Development of the management system, where it was made and approved, 3) Enforcement of the management system, where the results were evaluated, propose the necessary improvement and define the final system version. The main results founded were: (a) the definition of necessary abilities for a person who will be the change agent, responding for the system implementation, (b) the final management system version porpose, (c) the definition of the each step's right application moment, (d) the viability demonstration of applying the proposed method thru the financial results.The results prove the necessity of developing a own management methodology for the construction companies, looking for a better results and rising the quality of the final product.
