Within COSSERP ‘s numerous job planning and job estimating software management tools, are calculators. For those with unique requirements, calculators can be user-defined for materials and resources. Material calculators can be used for any requirement calculations including parametric calculations and unit of measure calculations. Resources calculators can be used for performance and time calculations primarily to determine time requirements on available resources. Once set up it becomes a matter of simply inserting dimensions or parameters. This provides flexibility during estimating and planning to deliver precise calculations of materials and operation run times.
