Clear answer, explained.

Smaller warehouses can often be completed in a few days to 1–2 weeks , while larger facilities or multi-building sites may take 2–4 weeks or longer . Projects are commonly staged in sections or completed outside operating hours to minimise disruption to operations. Additional time may be required for audit, design, procurement, or rebate approvals , but the physical installation itself is typically efficient.
