General Conditions Calculator

Walk through actual general conditions line items for a construction project. All defaults are editable — override with your rates and quantities.

How This Works

General conditions (also called "General Requirements" or Division 01 costs) represent the overhead of running a construction project — staffing, temporary facilities, insurance, and project-level expenses that aren't tied to a specific trade.

Typical general conditions range from 8-15% of total construction cost, varying by project size, duration, complexity, and location. Larger projects tend toward lower percentages; complex healthcare or renovation projects trend higher.

How to use:

Enter your project cost, duration, and location
Review each line item — defaults are Mid-Atlantic market estimates for a $10M commercial project
Override any value by clicking and typing your actual rate or quantity
Monthly items auto-multiply by project duration
The summary bar updates in real-time as you adjust

Default rates: Based on 2025-2026 Mid-Atlantic market conditions for commercial construction. Salary ranges reflect fully-burdened costs (salary + benefits + burden). Adjust for your local market using the location factor, or override individual rates.

Note: This calculator provides a structured framework — not a quote. Every project has unique general conditions requirements. Use this as a starting point and adjust based on project-specific scope, contract terms, and local conditions.
