public class UnitCostEstimateBaseClass extends Object implements Serializable
Base class for equipment cost estimation.

This class provides comprehensive cost estimation methods for process equipment based on chemical engineering cost correlations. It supports multiple cost estimation methodologies and provides JSON export capabilities for integration with project cost systems.

Cost estimation features include:

  • Purchased Equipment Cost (PEC) - base cost from correlations
  • Bare Module Cost (BMC) - includes installation, piping, instrumentation
  • Total Module Cost (TMC) - includes contingency and engineering
  • Grass Roots Cost - for new facility construction
  • Operating cost estimation
  • Labor man-hours estimation
  • Bill of Materials generation
