RFI vs Addendum BI
RFI
- Asks question
- Seeks clarification
- No automatic change
Addendum
- Formal pre-bid issue
- Changes procurement documents
- Reaches all bidders
- Question vs formal change
Document Picker BI
- Need design approach → RFP
- Need qualifications or quote → RFQ
- Bidder needs clarity → RFI
- Pre-bid change → Addendum
- Post-award scope change → Change order
- Installed condition → Record drawing
Bid Documents BI
- RFP Evaluate approach + capability
- RFQ Qualifications or quotation request
- Bidder RFI Requests clarification
- Addendum Formal pre-bid change
- Substitution Needs measurable equivalence
- Bid leveling Normalize proposal scope
- Bid form Standardize proposal response
- Alternate Priced scope option
- Allowance Owner-set cost placeholder
- Unit price Per-unit adjustment basis
Submittal vs Change Order IN
Submittal
- Proposed products
- Checks general conformance
- No scope waiver
Change order
- Authorized scope change
- Tracks cost + time
- Updates contract
- Conformance vs authorization
Acceptance Picker IN
- Measure optical loss → OLTS
- Locate fiber event → OTDR
- Accept fixed copper → Permanent-link test
- Check complete channel → Channel test
- Hidden work pending → Field observation
- Defect corrected → Retest
Field Support IN
- Submittal Proposed compliance evidence
- RFI Question seeking direction
- Change order Authorized contract change
- Field observation Visible-work review
- Nonconformance Document unmet requirement
- Punch list Remaining corrective work
Punch List vs Completion IN
Punch list
- Remaining deficiencies
- Corrective actions
- Tracked to closure
Substantial completion
- Usable intended purpose
- Contract milestone
- Minor work remains
- Open items vs milestone
Testing + Acceptance IN
- Certification Test against limits
- Qualification Estimate application support
- Reference method Defined test baseline
- Calibration Current instrument evidence
- Remediation Correct then retest
- Acceptance Criteria-based approval
Closeout IN
- Record drawings Verified installed routes
- Test results Accepted link evidence
- Warranties Coverage + start dates
- Training Operations handoff
- Spares Documented turnover stock
- Substantial completion Usable intended purpose
Common Traps
Code vs standard
- AHJ interprets adopted code ≠ Contract references standards
Rated vs delivered
- Bandwidth is capacity ≠ Throughput is delivered
Extra vs diverse
- Extra strands add capacity ≠ Separate routes add resilience
Loss vs reflection
- Insertion loss attenuates ≠ Return loss reflects
Sealant vs system
- Material alone insufficient ≠ Listed assembly restores rating
Review vs responsibility
- Submittal checks conformance ≠ Installer retains responsibility
Question vs direction
- RFI asks ≠ Written authorization directs
Drawing vs reality
- Design shows intent ≠ Record shows installed
Last Minute
- 1. Domains: 10 / 66 / 9 / 15
- 2. Pass score is not published
- 3. AHJ enforces adopted codes
- 4. Survey before selecting solutions
- 5. Copper: permanent 90; channel 100 m
- 6. OLTS = loss; OTDR = events
- 7. Bonding equalizes; grounding references
- 8. Firestop is a listed system
- 9. RFI asks; addendum changes
- 10. Submittal approval waives no requirement
- 11. Observe work before concealment
- 12. Correct failures; then retest
- 13. Record drawings reflect installed work
- 14. Closeout transfers operational evidence
