CWICR Cost Calculator

Business Case

Problem Statement

Traditional cost estimation often produces "black box" estimates with hidden markups. Stakeholders need:

Transparent cost breakdowns
Traceable pricing logic
Auditable calculations
Resource-level detail

Solution

Resource-based cost calculation using CWICR methodology that separates physical norms (labor hours, material quantities) from volatile prices, enabling transparent and auditable estimates.

Business Value

Full transparency - Every cost component visible
Auditable - Traceable calculation logic
Flexible - Update prices without changing norms
Accurate - Based on 55,000+ validated work items

Technical Implementation

Prerequisites

pip install pandas numpy
