How to handle RFP addenda without missing a change
Treat every addendum as a change to the whole bid: read it on its own, update what it touches, acknowledge it and pass the relevant changes to the subcontractors who are pricing. Never overwrite earlier work, so you can see what changed.
The short version
An RFP rarely stays still. Addenda arrive while you are pricing, sometimes the day before closing, and each one can change a quantity, a product, a date or a requirement. The risk is not reading them. It is reading one, forgetting that your estimate, your subcontractor packages and your bid form were built on the version before it.
What an addendum can change
- Quantities and scope. Added or deleted work, or revised sheets that change counts.
- Products and specifications. A substitution, a new standard, a different finish.
- Dates. The bid closing time, site visits, the schedule and substantial completion.
- Requirements. Bonds, insurance limits, forms and the way the bid must be submitted.
- Answers to questions. Responses to RFIs, which may be binding on everyone bidding.
A checklist that prevents the usual mistakes
- 1
Log it the day it arrives
Record the addendum number and date. Later addenda win where they conflict with earlier ones.
- 2
Read it alone
Read what the addendum itself says before comparing it with the rest. You are looking for the change, not rereading the whole set.
- 3
Update what it touches
Go through the estimate, the schedule, the subcontractor packages and the requirements list and change what the addendum affects.
- 4
Tell your subcontractors
Send the changes that matter to the trades who are pricing, so their bids match the current documents.
- 5
Acknowledge it on the bid
Bid forms often require every addendum to be acknowledged, and a missing acknowledgement can make a bid non-compliant. Check the form instructions.
- 6
Keep the trail
Do not delete the old numbers. If you can see what changed and when, you can explain it later.
How ScopeMark handles addenda
- Documents are labelled. When you upload, you say which file is a specification, a drawing, bid instructions or an addendum, with its number and issue date. ScopeMark then reads addenda as addenda, with later ones winning.
- An addendum is read on its own. It is not run through the whole document set again. ScopeMark sends just that PDF with a compact index of the current analysis and gets back the changes in plain words and the patches to apply.
- Nothing is deleted. A superseded item is flagged as withdrawn, a changed one keeps its previous value and everything touched is marked with the addendum's name, so your earlier decisions and reviews stay valid.
- Stale work is surfaced. An unreviewed addendum is flagged on the RFP. The estimate lists quantities an addendum changed, added or withdrew, with a button to apply each one, and the estimator stays in control.
- The bid checklist reopens. An item that was ticked but no longer matches the documents is reopened and says what changed, and each addendum gets its own "acknowledge" item.
- Where the effect is unclear, it says so. If an addendum revises sheets whose effect on counts cannot be seen, ScopeMark adds a gap for a person to resolve instead of guessing.
- Answers can travel. Reviewed addenda and answered RFIs can be shared as clarifications with the subcontractors invited to a trade package.
The AI reads for a person to review. It never submits a bid, and what it cannot verify is shown as unknown.
Questions people ask
What is an addendum in an RFP?
An addendum is an official change or clarification issued by the owner after the RFP is published. It can change scope, quantities, dates or requirements, and later addenda take priority over earlier ones.
What happens when an addendum changes the RFP in ScopeMark?
ScopeMark reads the addendum on its own and updates the existing analysis without deleting anything. Changed items are flagged with the addendum's name, changed quantities are listed on the estimate and bid-checklist items that no longer match are reopened.
Do I need to re-run the whole analysis for each addendum?
No. Each addendum is reviewed by itself and patched into the latest analysis, which is quicker and keeps your earlier work and ratings in place.
Does ScopeMark acknowledge addenda for me?
No. It adds an acknowledgement item for each addendum to your bid checklist, and a person completes the bid. ScopeMark submits nothing.
Does ScopeMark hold or move our money?
No. ScopeMark does not process payments between companies and subcontractors. The buyer pays directly, outside ScopeMark, and records the payment. ScopeMark's only revenue is its subscription.
