Timber
The complete timber system requires approximately 4,130.5 m³ of felled timber each year and 82,609.5 m³ over twenty years. That is approximately 60.19 Snefru-ship equivalents annually and 1,203.8 over the build. Ship equivalents describe the scale of the complete timber system; they do not mean that every cubic meter is imported cedar. Under the model’s 50% native-timber concession, the literal imported requirement is approximately 30.09 shiploads a year and 601.9 over the build. That is 15.05 times the forty-ship documented delivery.
