What Is in a Bid Document Set?
Bid sets commonly include:
- Invitation to bid or solicitation.
- Instructions to bidders.
- Bid form or proposal form.
- Required certifications and attachments.
- Bid bond or bid security forms.
- Drawings.
- Specifications.
- General and supplementary conditions.
- Addenda.
- Geotechnical or existing-condition information when provided.
- Alternates, allowances, and unit-price schedules.
- Contract execution requirements.
The owner or procurement instructions define the required set.
First Pass: Confirm Completeness
Before estimating, confirm:
- The document list matches the files received.
- Drawing dates and revisions are current.
- Specification sections are present.
- Addenda have been downloaded.
- Bid forms are included.
- Submission instructions are clear.
- Mandatory meeting notes are included when provided.
If anything is missing, ask the plan room, issuing agency, or procurement contact before proceeding.
Drawings Review
Assign drawing review by discipline:
- Civil and site.
- Architectural.
- Structural.
- Mechanical.
- Electrical.
- Plumbing.
- Fire protection.
- Specialty systems.
Review plans, elevations, sections, details, schedules, notes, and referenced sheets. Capture unclear scope and coordination issues in the bid question log.
Specifications Review
Specifications often define product, quality, administrative, and execution requirements. Contractors should review:
- Division 00 procurement and contracting requirements.
- Division 01 general requirements.
- Trade-specific technical sections.
- Submittal requirements.
- Testing and inspection requirements.
- Acceptable products and substitution rules.
- Warranty and closeout requirements.
Use the bid specifications guide for a deeper review process.
Addenda Review
Addenda can change scope, deadlines, forms, alternates, or answers to bidder questions. Track:
- Addenda number.
- Issue date.
- Changed drawings or specifications.
- Changed bid date.
- Changed forms or submission instructions.
- Required acknowledgment.
Addenda review should happen again during final bid checks.
Instructions to Bidders
Instructions to bidders may control:
- Bid date and time.
- Submission location or portal.
- Required forms.
- Bid security.
- Mandatory meetings.
- Question deadline.
- Addenda acknowledgment.
- Subcontractor listing.
- Alternates and unit prices.
- Withdrawal and award procedures.
These instructions are just as important as the drawings.
RFI and Clarification Workflow
Submit questions when documents are unclear, conflicting, incomplete, or materially affect price. A useful RFI includes:
- Document reference.
- Clear question.
- Why the issue matters.
- Suggested interpretation when appropriate.
- Deadline sensitivity.
Save owner responses in the bid folder and share them with affected estimators, subcontractors, and suppliers.
Final Submission Checklist
Before submitting:
- Confirm all addenda.
- Review base bid and alternates.
- Confirm unit prices and allowances.
- Confirm bid bond or bid security.
- Complete every required form.
- Verify signatures and entity names.
- Check subcontractor lists when required.
- Confirm portal upload or delivery instructions.
- Save the submitted package and confirmation.
For timing controls, use the construction bid validity guide.
