SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill delivers disciplined, CSI-driven ground-up construction cost budgets by dividing hard costs across CSI divisions, applying regional factors, and layering soft costs, contingencies, and financing.

Core Features & Use Cases

  • CSI Division Cost Buildup (01-33) with a bottom-up hard cost per SF and per-division breakdown.
  • Regional Cost Adjustment using city multipliers, labor premiums, and site-specific mobility factors.
  • Site-Specific Adjustments for demolition, remediation, shoring, and utilities.
  • Soft Cost Estimation with benchmark percentages and financing costs methodology.
  • Contingency Framework by design stage and risk category.
  • TDC Summary integration of land, hard costs, soft costs, contingencies, and reserves.
  • Sensitivity Analysis to explore Low/Base/High scenarios and cost drivers.

Quick Start

Provide a project profile and run the estimator to produce a complete TDC budget including hard costs, soft costs, contingencies, and financing.

FAQPage Schema
How do I calculate total development cost for a ground-up construction project?

To calculate total development cost, integrate CSI division hard costs, regional multipliers, site adjustments, soft costs, contingencies, and financing into a comprehensive TDC budget. This estimator applies bottom-up per-SF buildup across all CSI divisions to generate the final summary.

What is CSI division cost buildup and how does it adjust for regional factors?

CSI division cost buildup is a bottom-up hard cost estimation method dividing expenses across divisions 01-33. Regional adjustment applies city multipliers and labor premiums to the base CSI costs, ensuring the budget reflects localized construction economics accurately.

Can I estimate soft costs and contingencies for adaptive reuse projects?

Yes, you can estimate soft costs and contingencies for adaptive reuse projects. The estimator applies benchmark percentages for soft costs, uses a contingency framework based on design stage and risk category, and integrates specific site adjustments like shoring and remediation.

How do I run a sensitivity analysis on a construction cost budget?

Run a sensitivity analysis on a construction cost budget to explore Low, Base, and High scenarios by adjusting key cost drivers. This process identifies how regional factors, site-specific conditions, and contingency allocations impact the final total development cost.

Does this construction cost estimator work for gut renovation and capital improvement projects?

This estimator works for ground-up, gut renovation, adaptive reuse, and capital improvement projects. It applies CSI division costs, regional cost multipliers, and site-specific adjustments across varied locations to produce a complete TDC budget for each project type.

What site-specific adjustments are included in a total development cost budget?

Site-specific adjustments in a total development cost budget include demolition, remediation, shoring, and utility costs. These adjustments layer onto the CSI division hard costs and regional multipliers to capture unique site conditions impacting the overall project budget.
