Classify each bid item

Classify the item before building its price. Follow the bid form and contract language.

Use identifiers that match the proposal. For construction bid alternates and allowances, use this related guide as context while keeping the current project documents in control.

Protect the base bid

Complete the base estimate before adding options. State which base material an option replaces. Keep option qualifications separate from base notes.

Price net alternates

Include removed and added work in a net alternate. Check overlaps between combinations of options.

Retain the detailed build-up behind each amount. When reviewing construction bid alternates and allowances, consult AACE International for cost-engineering context, then apply it through the contractor’s own standards.

Name the scope and basis of every allowance. Do not hide measurable work in an allowance. Follow contract rules for allowance adjustments.

Reconcile accepted options

Test proposal totals under likely combinations. Review fee, bond, tax, and insurance treatment.

Transfer accepted items into the award handoff. For recurring construction bid alternates and allowances records, an estimating support role can maintain inputs while final approval stays with the contractor.
