6. What next? Goal: early start production
Check numbers & priority items;
Prepare “preliminary1” drawings for an informal offer by end June (doable?)
Do “final2” drawings by mid-July
preliminary is before the 3D model is frozen
final is after 3D model is finished (in the assumption differences between preliminary & final) are small.
