What this skill does
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 Python Implementation Quick Start Common Use Cases 1. Project Estimate 2. QTO Integration 3. Regional Adjustment Resources GitHub: OpenConstructionEstimate-DDC-CWICR DDC Book: Chapter 3.1 - Construction Cost Estimation
