Cost Estimating


Organize Estimates and Reporting Costs in multiple coding structures for the Nuclear Sector such as IAEA -International Atomic Energy TRS396 and CANDU BSI. At early phases of the Estimates Class2 or 3, the estimators with experience can create parametric models to quickly size the equipment needed and produce estimates.

Key Features

  • Create estimates for network assets in seconds
  • Powerful Parametric Estimating Engine
  • Use GIS takeoffs to define your Network lines within parametric models
  • Supports multiple hierarchical coding structures and the ability to organize, sort and filter the data by any means
  • Access multiple commercial Online Databases for Utilities Equipment
  • Set up escalation factors for commodities over many decades and adjust for uncertainties the costs
  • Web based app for easy access on the GO
