Bid leveling separates successful general contractors from those who constantly face budget overruns and subcontractor disputes. This critical estimating skill ensures you're comparing equivalent scopes when evaluating subcontractor proposals, preventing costly surprises during construction.
What Is Bid Leveling?
Bid leveling, also called bid analysis or bid comparison, is the process of normalizing subcontractor quotes to ensure accurate apples-to-apples comparisons. Because subcontractors interpret scopes differently and present pricing in various formats, raw bid comparison often leads to selecting the wrong contractor.
Why Bid Leveling Matters
Cost Accuracy:
- Lowest bid isn't always best value
- Scope gaps become change orders
- Exclusions hide true project costs
- Qualification differences affect outcomes
Risk Management:
- Identifies incomplete scopes early
- Reveals unrealistic pricing
- Exposes coordination gaps
- Highlights qualification concerns
Relationship Protection:
- Prevents scope disputes during construction
- Sets clear expectations upfront
- Builds trust through transparency
- Reduces change order negotiations
The Bid Leveling Process
Effective bid leveling follows a systematic approach that examines every aspect of subcontractor proposals.
Step 1: Scope Analysis
Begin by creating a comprehensive scope checklist from contract documents.
Specification Review:
- List every section applicable to the trade
- Note performance requirements vs. prescriptive specs
- Identify quality standards and testing requirements
- Document submittal and approval requirements
Drawing Analysis:
- Mark every location requiring the trade's work
- Note quantities and areas for major items
- Identify coordination requirements with other trades
- Document access and staging constraints
General Conditions Impact:
- Project schedule requirements
- Site access and logistics
- Safety and security requirements
- Documentation and meeting attendance
Step 2: Bid Receipt Organization
Organize received bids for efficient analysis.
Standard Information:
- Contractor name and contact information
- Bid date and validity period
- Total base bid price
- Alternate pricing if requested
Scope Documentation:
- Inclusions listed by the subcontractor
- Exclusions explicitly stated
- Qualifications and clarifications
- Assumptions made by bidder
Supporting Materials:
- Insurance certificates
- Bonding commitment letters
- Safety statistics
- Reference information
Step 3: Line-Item Comparison
Create a comparison matrix breaking down each bid into component parts.
Cost Categories:
Labor:
- Base labor hours by task
- Labor rates applied
- Overtime assumptions
- Productivity factors
Materials:
- Major material quantities
- Specified products vs. substitutions
- Delivery and handling
- Waste factors
Equipment:
- Required equipment types
- Rental vs. owned equipment
- Mobilization costs
- Operator labor
Overhead:
- Job-specific overhead items
- Company overhead allocation
- Profit percentage
- Contingency amounts
Step 4: Scope Gap Identification
Compare each bid's scope against your checklist to identify gaps.
Common Scope Gaps:
Mechanical Trades:
- Controls and commissioning
- Balancing and testing
- Insulation responsibilities
- Equipment startup services
Electrical Trades:
- Fire alarm vs. low voltage scope
- Generator connections
- Temporary power provisions
- Testing and certification
Finish Trades:
- Surface preparation responsibilities
- Protection during construction
- Touch-up and repair
- Final cleaning scope
Step 5: Price Normalization
Adjust prices to reflect equivalent scopes.
Add-Back Analysis:
- Identify excluded items from low bidders
- Obtain pricing for missing scope
- Add to base bid for true comparison
- Document assumptions used
Credit Identification:
- Note duplications between trades
- Identify overages in high bids
- Calculate reasonable credits
- Adjust for actual scope needed
Advanced Leveling Techniques
Sophisticated contractors use additional techniques for complex bids.
Unit Price Analysis
Compare unit prices for major bid components:
Benefits:
- Reveals pricing methodology differences
- Identifies potential quantity errors
- Enables scope-specific comparisons
- Supports negotiation discussions
Application:
- Calculate unit prices from bid breakdowns
- Compare against historical data
- Identify outliers for investigation
- Adjust for project-specific factors
Productivity Assessment
Evaluate the implied productivity rates:
Labor Hour Analysis:
- Calculate implied production rates
- Compare against industry standards
- Assess achievability given site conditions
- Identify unrealistic assumptions
Schedule Implications:
- Duration requirements vs. bid assumptions
- Crew size and composition
- Multiple shift capabilities
- Weather and access impacts
Financial Analysis
Assess each bidder's financial proposition:
Payment Terms:
- Progress billing frequency
- Retainage requirements
- Payment timeline expectations
- Material storage billing
Cash Flow Impact:
- Front-loaded vs. back-loaded pricing
- Material procurement timing
- Mobilization payment needs
- Retainage release expectations
Creating the Bid Comparison Matrix
A well-designed comparison matrix facilitates decision-making.
Matrix Structure
Column Organization:
- First column: Scope items from checklist
- Subsequent columns: One per bidder
- Final columns: Leveled totals and notes
Row Categories:
- Base bid summary
- Major scope item breakdown
- Exclusions with add-back pricing
- Qualifications with cost impacts
- Leveled comparison total
Visual Presentation
Highlighting Techniques:
- Color-code included vs. excluded items
- Bold significant variances
- Flag items requiring clarification
- Mark recommended selections
Bid Leveling Best Practices
Follow these practices for consistent, reliable results.
Documentation Standards
Maintain Clear Records:
- Save original bid documents unchanged
- Document all assumptions made
- Record conversations with bidders
- Preserve decision rationale
Version Control:

- Track revisions as clarifications received
- Maintain audit trail of changes
- Archive final versions
Communication Protocols
Bidder Interactions:
- Ask clarifying questions in writing
- Request written confirmation of verbal statements
- Distribute clarifications to all bidders fairly
- Document all communications
Internal Reviews:
- Present leveling to project team
- Obtain senior review for large awards
- Document approval of selection
- Record any override decisions
Timeline Management
Leveling Schedule:
- Begin immediately upon bid receipt
- Allow adequate time for clarifications
- Complete before award deadline
- Factor in negotiation time if needed
