How to Use This Calculator
  1. Enter the total number of steel pieces in the submittal package and the count of unique connection details.
  2. Enter the number of embed plates (requiring concrete coordination) and the current revision number.
  3. Set the count of outstanding RFIs related to this submittal.
  4. Read Estimated Review Hours and Turnaround Days to plan your review schedule and track submittal deadlines.
  5. Check Checker Level (1=Junior through 4=PE required) to assign the appropriate reviewer.
  6. Use Complexity Score to justify extended review durations with the contractor when the package is complex.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Total Pieces = 150, Connection Details Count = 30, Embed Plates Count = 20, Revision Number = 0 = 5 input(s) provided
  2. Calculate Estimated Review Hours
    Estimated Review Hours = subtotalHours * revisionMultiplier
    32.1 = 32.1
  3. Calculate Complexity Score
    Complexity Score
    75 = 75
  4. Calculate Turnaround Days
    Turnaround Days
    9 = 9
