ASI, RFI, and Change Orders: The Distinct Construction Documents Contractors Constantly Mix Up
Construction contract administration involves distinct documents with specific purposes. The Architect's Supplemental Instructions (ASI), the Request for Information (RFI), the Construction Change Directive (CCD), and the change order (CO) each serve different functions under the standard contract — typically AIA A201 or similar general conditions. Contractors sometimes respond to these documents interchangeably, which creates disputes about authority, scope, and cost.
Understanding the distinctions protects contractors. An ASI is not a change order. A change order is not an RFI response. A CCD is different from both. This post covers the documents and how to handle each appropriately.
RFI is contractor asking for clarification:
RFI characteristics
- Initiated by contractor
- Asks for clarification of documents or conditions
- Expects response that clarifies existing scope
- Does not itself authorize scope changes
- Response should not expand scope (or it's effectively a change)
- Tracks via RFI log
RFI response that clarifies existing scope is normal contract administration. RFI response that changes scope effectively becomes a directive — requiring formal change order process or becoming basis for change claim.
ASI is architect providing direction:
ASI characteristics
- Issued by architect (typically on AIA G710 form)
- Provides direction or clarification
- Intended for minor changes not involving adjustment to contract sum or time
- Architect's interpretation of contract documents
- Contractor to proceed with instructions
- Contractor reserves rights if ASI involves scope change or cost
ASIs are one of the most commonly-misunderstood documents. They're intended for minor clarifications — not for scope changes with cost. When architect issues ASI that effectively adds scope, contractor should respond promptly identifying the cost/time implication and requesting formal change order.
CCD is owner directing change with disputed terms:
CCD characteristics
- Issued by owner (AIA G714 form)
- Directs contractor to proceed with change
- Used when contractor and owner can't agree on terms in advance
- Contractor proceeds while cost and time are determined later
- Cost determined by methods specified (lump sum, unit prices, time and materials)
- Time determined similarly
- Results in formal change order once terms resolved
CCD is the mechanism for owner to direct changes contractor and owner can't agree on pricing for in advance. Work proceeds; cost and time are determined after. CCD is proper authority — contractor can bill for work under CCD even before final change order.
Change order is formal modification:
Change order characteristics
- Formal amendment to contract
- Signed by owner, architect, and contractor
- Specifies scope change, cost adjustment, time adjustment
- AIA G701 or similar form
- Modifies contract sum, contract time, or both
- Proper authority for billing the change
Change order is the proper contractual mechanism for scope changes. All other documents (RFI responses, ASIs, CCDs) ultimately should be converted to change orders for scope changes. Executing work without change order (or CCD) exposes contractor to argument that the work was within original scope.
When an ASI, RFI response, or other document effectively expands scope, contractor should promptly (ideally before performing the work) notify the owner/architect that the instruction appears to constitute a change, request formal change order, and preserve rights if directed to proceed without one. Performing extra work and billing for it after the fact is harder than establishing the change upfront.

Authority to Direct
Different parties have different authority:
Contract authority by document
- Architect issues ASIs for minor clarifications
- Architect has no authority to change contract sum or time without owner
- Owner directs changes via CCD when not agreed in advance
- Owner, architect, contractor sign change orders
- Field representatives typically don't have authority to direct changes
Authority matters for liability and payment. Field changes directed by representatives without proper authority may not be paid. Verifying authority before proceeding with directed changes protects contractor.
Different documents need different responses:
Contractor response matrix
- RFI response within scope — proceed normally
- RFI response expanding scope — notify and request change order
- ASI minor clarification — proceed normally
- ASI with scope/cost implication — notify and request change order
- CCD — proceed and track costs per CCD terms
- Change order — execute and bill accordingly
- Verbal direction — request written
Response discipline matters. The contractor who proceeds without raising the scope/cost issue, then bills for it later, faces the argument that silent performance means no change was understood. The contractor who promptly raises the issue preserves the change.
Documentation protects all parties:
Documentation practice
- Log all documents with dates and references
- Written response to ASIs that change scope
- Track CCDs until converted to change orders
- Change order log with amounts and status
- Copies to file per contract requirements
- Records retention per contract
Organized documentation supports contract administration. When disputes arise years later, the documentation either supports or undermines claims. Good documentation practices cost little; poor ones can cost substantial recovery.
RFI, ASI, CCD, and change order are distinct documents with different purposes and authority. RFIs clarify existing scope; responses shouldn't expand scope without change order. ASIs are minor architect clarifications; ASIs that expand scope should trigger change order request. CCDs are owner-directed changes pending pricing resolution; contractors proceed and track costs. Change orders are formal contract amendments — the proper authority for scope changes. Contractors who respond appropriately to each document protect their right to be paid for extra work. Contractors who respond interchangeably face disputes about authority, scope, and compensation. Contract administration discipline is low-cost protection against substantial disputes.
