  notes: |
    Total ≈ 2500 manhours of installation + programming + T&C + training labor.
    Plus PM/engineering overhead in WBS 1.x (separately captured in General Requirements section).
    Production-rate modifier 1.20× covers multi-station coordination overhead per A-301.
    FAT witness labor 112 hr separate from FAT travel cost (which is in BOQ separate line items per D-016).
