In our country, the planning and control of construction projects will be carried out using specific methods in use (Kelley, 1964), such as the critical path method (CPM) and the project evaluation and review technique (PERT), which were introduced in the 1950s by Kelly and Walker (1959) and Malcolm (1959) respectively. While Stradal and Cacha (1982) and Arditi (2002), criticized the lack of interest in the workflow of the crews, where the interruption of these is not desirable for most workers, because time and turnover are lost. Specific tasks, and the common effect of this malpractice, is what teams leave the site, to work on another project, which implies a late return and an additional interruption in the workflow. Another common effect is that the crews are moved to the available locations, without finishing the work started, this complicates the control effort and can cause rework, also opening many work fronts and not closing them, limits accessibility to other work equipment Nor does it illustrate conflicts related to simultaneous work in the same location and productivity problems due to mismanagement. The thesis is based on the theoretical Value - Flow - Operation (VFO) of Sven Bertelsen, which was described as the interaction of three flows, which shows the complex and dynamic nature of the construction system, therefore the systematic combination will relate the BIM methodology. using your Autodesk A360 Fusion tool to define value from the customer's perspective, and obtain the basic quality, scope, quantity and location requirements for each task; on the other hand, Lean construction will help manage flows to ensure conversion of the final product. While the location-based management system (LBMS) methodology was used for time management, in project planning and control, it uses tools such as flow lines (LF), which gives importance to continuous workflow. ; The Last Planner System (LPS) developed by Ballard G. (1994) & Howell G. (1998), combines the Plan Percent Performed (PPC) theory as an indicator to increase planning reliability by tracking complete units per week, for each small location. The location-based management system (LBMS) had major contributors to Lumsden in the 1960s, Selinger and Peer in the 1970s, Mohr in the late 1970s, Russell in the early 1980s, Kankainen in the late 1980s, Arditi in the 2000s, and Kenley and Seppänen in the 2000s and 2010s, this system enables better visualization of each location and improves continuity of workflow. Therefore, the tools used are the balance line (LOB) and the flow lines (LF), where LOB was used for the master scheduling, for our contractual term, later we will obtain a greater amount of information when planning more detailed, such as division of locations, quantity by location, productivity rates, and optimal grid analysis to plot LFs for a complex and dynamic project; then buffer was added to each task if warranted according to risk management, to know the critical and non-critical tasks that can be represented as continuous or parallel lines respectively in the planning. The flow of information through information and communication technology (ICT), uses the WhatsApp tool developed by Cruz J. (2017), which generated information on daily requirements and progress of work. While, the Trello tool helped to make commitment charts with those responsible for each front, on the other hand, quality and safety are intrinsic to each general contractor. The control of projects with the LBMS was carried out periodically, analyzing the 7 preconditions to ensure the continuous flow of tasks, while the validation of the product was carried out through daily and weekly supervision to see quality issues and compliance with the plan. While the forecast of the flow lines were represented with dotted lines, for the weekly projections, this generated alarms that prevent more abrupt delays in the subsequent tasks, control charts were also used to analyze the daily progress by location, these were corroborated by the PPCs to know the reliability of the workflow; on the other hand, the waste analysis of each production line will have a Lean approach, to obtain the new production rates for the next similar projects.
