Contemplating the problem generated by the low capacity of the construction sector in the houses located in the high Andean zone of Peru and the regulation of buildings, in this article we will seek to improve and optimize the execution processes in the highlands of Peru applying the methodologies of work of LEAN CONSTRUCTION-BIM METHODOLOGY for small and medium-sized companies, thus applying tools that generate value to the activities in the execution process, thus eliminating all types of material loss, seeking to reduce costs, increasing the collaboration of the work team and reducing the execution time of the work and the prevention of accidents, a study stage of the problem will be carried out, thus applying a small modeling with BIM where we will propose a minimum and adequate standard for constructions in the highlands of Peru and applying a standard of LOOK AHEAD for optimal progress of the work. It is known that in our country there are areas that are far from the main city, so they are excluded from everything. To talk about the types of construction forms and structures is to mention the precariousness that they have and where people are affected.
