Stages
KM design (structural drawings) takes 2–3 weeks, KMD (shop drawings) another 2. Manufacturing — from 30 days depending on the tonnage. Foundations — 3–6 weeks. Erection — from 3 weeks.
Foundations can be poured while the plant manufactures the frame, and manufacturing can start from finished KMD sheets without waiting for the whole design.
Where time is lost
Most often in approvals: changes to the process after the KMD is issued shift manufacturing by weeks. Fix the equipment loads before design starts.
