The steel plant usually issues base-plate drawings and a bolt list; local civil works build the foundations. Projection, nut count and grout thickness follow the approved drawing. Civil delay stops lifting, so the interface belongs on the programme.

Check foundations and bolts before the crew arrives. Zone laydown by mark. If a bolt is out of place, stop that bay.

Grout and base coating are common handover items; the contract list governs. No single bolt grade is set here.

Say who supplies foundations and erection. Ask for base-plate data in the scheme, not after delivery.

Tiankai Southeast fabricates marked members from approved drawings and supports erection by mark number. Sizes, loads and delivery follow the confirmed design file and contract; this page does not turn uncalculated tonnage, thickness or time into a promise.
