The use of heavy equipment in civil engineering, mining and large-scale earthmoving works is almost inevitable. In fact,this tool is a factor that really determines the successful completion of work on time in accordance with the required quality. When compared to human labor using simple conventional equipment such as hoes, shovels, baskets, pounding tools for compaction and so on, using heavy equipment has many advantages that promise benefits. Moreover, if a job requires technical requirements and high precision, then the choice of using heavy equipment is a very appropriate alternative. The advantage of using heavy equipment compared to manual tools is that you can complete construction work more quickly. Apart from optimizing working time, construction costs can also be adjusted. Tool productivity depens on the type of tool, worj method, work area conditions and the time needed to complete a job. So, an analysis of the calculation of the heavy equipment requirements required and an analysis of the implementation time required by each tool is required, taking into account the calculation steps, namely: calculating the production capacity of each heavy equipment in order to obtain the productivity value, so that the number of each tool required can be determined.
