On a phased steel project, the total tonnage delivered can look satisfactory while an individual work area is still missing a few beams or a package of connection items. At the same time, another area may be occupied by components that are not yet needed. Zhonghengfeng’s October 5, 2026 guidance uses a 10,000-tonne phased-project scenario to explain how a buyer and fabricator can agree area-based supply before production begins.
When a separate area-based supply plan is useful
The source identifies four situations: construction proceeds by phase, building or grid-line zone; unloading and storage space are limited; the next operation needs a complete set of members and connection items; or shop drawings are approved and frozen in separate packages. If any of these applies, a single overall delivery date may not adequately describe the required supply sequence.
The method can be recorded in a contract appendix or technical agreement. It does not prescribe commercial terms or a fixed number of delivery days.
Confirm the area boundaries and demand sequence in writing
The buyer or designer should provide the area definitions and their required order in writing. Areas may follow individual buildings, grid-line sections or systems. Requirements from the party responsible for subsequent site operations should be consolidated through the buyer.
The factory then plans its production batches around the confirmed sequence. It does not decide the buyer’s area priorities. Any later sequence change should be confirmed in writing rather than introduced through an oral instruction.
Define a complete supply set for each area
Prepare a separate list for each area, identifying member marks, the parts and connection items to accompany that area, and the applicable shop-drawing revision. Whether high-strength bolts, packing plates or other items travel with a particular batch depends on the contract.
The agreement should state which listed items must all be dispatched before the area’s supply is considered complete. If partial dispatch is allowed, define how outstanding items are shown. Area lists, packing lists and component marks should use consistent identifiers so that receipt can be checked item by item.
Freeze batches and separate different kinds of change
Before production of each batch, freeze its area list and shop-drawing revision. Later additions or removals should follow the agreed drawing-approval and change process. Any commercial or delivery effect requires a separate written agreement.
Record a change in area priority separately from a drawing revision. This preserves a clear explanation of why a batch changed and which instruction affected it.
Close shortages, excess items and receipt records
- Align each arrival window with the buyer’s confirmed unloading and storage capacity before dispatch.
- Use the agreed receipt-inspection process to record shortages, damage and unpacking results for each batch.
- For an item missing across several batches, the receiver should submit a written notice; the factory should reconcile the lists and confirm the replacement batch in writing.
- Agree the treatment of excess or incorrectly delivered items in writing.
- Supply the agreed, verifiable records with each shipment.
Keep the manufacturing and site interfaces separate
The factory’s stated interface is to manufacture to the frozen revision, organize batches by area, and deliver the agreed complete set of protected components and accompanying records at the contractual delivery point. Unloading, internal site transport, storage and the sequence of subsequent site operations belong to the parties identified in the contract.
Before the first area begins, foundation and embedded-anchor handover measurements should be addressed through a separate interface agreement. This article develops the area-and-batch element of a delivery plan; it does not replace the separate requirements for drawing changes, packing, receipt inspection or foundation handover.
This guidance concerns the steel fabrication and supply interface. The contract and technical agreement determine the actual responsibilities; it does not offer EPC general contracting or assume responsibility for site installation.
Zhonghengfeng can discuss area-based supply lists and batch planning for phased projects within its steel fabrication and supply scope. The scope of a preliminary technical discussion is agreed separately.
