How to Prepare a Detailed Construction & Contractor Quotation
A practical guide for general contractors, civil engineers, and trade specialists to estimate materials, labor, equipment, and contingencies.
Construction and contracting quotations demand higher granularity than standard retail quotes due to material price fluctuations and site variables.
### Recommended Groupings for Contractor Quotes
- **Group A: Site Mobilization & Demolition** (Safety fencing, permits, debris removal)
- **Group B: Raw Materials & Supply** (Concrete, lumber, rebar, plumbing fixtures, drywalls)
- **Group C: Specialized Labor & Tradecraft** (Carpenters, licensed electricians, welders)
- **Group D: Equipment Rental & Machinery** (Scaffolding, excavators, lifts)
- **Group E: Contingency Allowance** (Usually 5% - 10% for unforeseen ground conditions)

Should a contractor show profit margins on the quote?
No. Build your profit margins and overhead into your unit labor rates and material markups rather than displaying a separate 'profit' line.
