Architects Supplemental Information (ASI) represents a formal document issued by an architect during construction.ASI documents provide additional details, clarifications, or minor modifications to construction documents after the project has started. This communication tool ensures all parties work with accurate and complete information.
Purpose and Function
ASI documents address questions that arise during construction.ASI documents resolve ambiguities found in original construction documents.ASI documents make small changes that do not affect project cost or schedule. These supplemental documents maintain project clarity without requiring formal change orders.
Common Applications
ASI documents typically cover the following areas:
- Material specifications: Clarifying specific types, brands, or grades of materials
- Dimensional details: Providing additional measurements for custom features
- Installation instructions: Adjusting methods for compliance with local codes
- Finish requirements: Specifying exact colors, textures, or application methods
- Code compliance: Addressing regulatory requirements discovered during construction
ASI vs. Change Order Comparison
The following table illustrates key differences between ASI and Change Orders:
| Aspect | ASI | Change Order |
| Scope impact | Minor clarifications only | Significant scope changes |
| Cost implications | No financial adjustments | Includes cost modifications |
| Schedule effects | No timeline changes | May affect project schedule |
| Approval process | Architect-issued | Requires formal approval |
| Documentation level | Supplemental information | Comprehensive contract modification |
Real-World Examples
Common ASI scenarios include:
- Clarifying paint specifications when original documents list generic requirements
- Providing additional dimensions for custom millwork or built-in features
- Adjusting installation details to meet updated building code requirements
- Specifying exact material grades when original specs were too general
- Detailing connection methods for unique architectural elements
Benefits for Project Teams
ASI documents provide significant advantages:
- Improved communication between architects and construction teams
- Reduced field questions through proactive clarification
- Maintained project quality by ensuring accurate implementation
- Streamlined workflow without formal change order processes
- Documentation trail for future reference and accountability
Distribution and Implementation
ASI documents are distributed to all relevant project stakeholders.Contractors must acknowledge receipt and understanding of ASI information.Project managers should integrate ASI details into their construction planning.Subcontractors should review ASI documents before proceeding with affected work.
Best Practices
Effective ASI management includes:
- Timely issuance when clarifications are needed
- Clear documentation of all supplemental information
- Proper distribution to all affected parties
- Acknowledgment tracking to ensure receipt and understanding
- Integration with existing project documentation systems
