Inspect the right state
Read the current quote for the exact building level or improvement. Record worker wages, planned material purchases and other obligations in the same period. The reference building ladder helps find prerequisites but does not establish the live amount you will pay.
Make the decision
Subtract committed expenses and the reserve you want to retain before comparing the upgrade cost. If the remaining cash is insufficient, reduce or delay the project. Do not call the upgrade profitable merely because its listed effect increases a capacity or stat.
Verify the result
After the upgrade, verify the changed building field and the actual cash movement. Track any additional output separately before attempting an ROI estimate; the archive leaves automatic ROI gated until the necessary current-build values are verified.
