Contractor Bid Estimating Services

Contractors need more than a basic construction estimate when competing for work. A successful bid needs coordinated quantities, material and labor costs, subcontractor pricing, general conditions, project requirements, markups, exclusions, and allowances. Our contractor bid estimating services help general contractors prepare accurate, competitive bids from construction drawings, specifications, addenda, bid forms, and other project documents.

Why Our Contractor Bid Estimates Hold Up

A general contractor's bid brings together multiple scopes and cost components.

Concrete, structural steel, framing, roofing, finishes, MEP, sitework, equipment, subcontractor proposals, and general requirements all need to be reviewed without duplicating or overlooking scope.

We build the estimate around the project's actual bid documents and organize the costs so contractors can review the complete bid before submission.

Built Around the General Contractor's Scope

We review the available drawings and specifications to identify the work that falls under the prime contractor's responsibility.

Where subcontractor proposals are provided, those proposals can be reviewed against the plans and scope requirements to identify apparent gaps, exclusions, or scope differences.

Subcontractor Proposal Review

When subcontractor quotations are available, we can incorporate them into the overall bid while reviewing the stated scope, exclusions, quantities, and allowances.

This helps the general contractor understand whether the proposal appears to cover the work shown in the bid documents.

Bid Leveling & Scope Comparison

When multiple subcontractor or supplier proposals are available, pricing can be organized for comparison.

Differences in scope, exclusions, allowances, unit prices, and alternates can be identified so the contractor can make a more informed bid decision.
