Our statewide team provides substitution evaluations support with emphasis on technical review of alternate products against capacity demands, detailing constraints, and code/performance criteria. Reviews and field coordination are structured to reduce uncertainty, limit rework, and keep permit and construction documentation aligned.

Construction Administration Requirements by County & Key Engineering Considerations

  • Substitution Requests Technical Accuracy
    Substitution evaluations compare structural capacity, stiffness, durability, and compatibility with approved design assumptions.
  • Substitution Requests Workflow Control
    Review comments document required conditions, limitations, and detail updates for safe implementation.
  • Substitution Requests Field Reliability
    Approved substitutions are coordinated into revised notes/details to maintain consistent permit and field documentation.
