The use of new information and communication technologies (ICT) can bring benefits to the management of construction sites, such as material savings, productivity growth and the enhancement in the speed of information transmission. To manage the supply of more than 62 blocks of 14 apartments each, spread over an area of 55 hectares, a team of engineers from a construction company in Fortaleza (Brazil) developed a system to schedule and track the progress of activities of forklifts on site in order to avoid idleness of these machines and workers waiting for materials. Thus, this paper describes a computerized system for distribution and leveling (heijunka) of forklift work, using tablets to inform operators about supply and cleanup activities to be performed at the jobsite. The work was developed in five steps: team training in lean construction concepts, recognition of real problems, system development as a problems solution, solution testing and identification of improvements and consolidation of results. Results were reductions of idle machines, work stoppage due to the lack of material and distance travelled. This computerized system has also improved the organization of construction site and the productivity of workers.
