Short answer: A greenhouse quotation is complete only when every design, supply, civil, logistics, installation, commissioning and operating responsibility is marked as included, optional, excluded or supplied by the buyer. Attach that responsibility matrix to the contract.
Greenhouse offers may use the same project name while pricing different work. One supplier may include design drawings, screens, control panels and installation supervision; another may quote only structure and covering. A clear matrix converts assumptions into reviewable contract items.
| Status | Meaning | Required record |
|---|---|---|
| Included | Part of the contract price | Quantity, specification, deliverable and acceptance method |
| Optional | Available at a separate price | Price validity and effect on other systems |
| Excluded | Not supplied or performed by the seller | Party responsible and interface information |
| By buyer | Owner or local contractor responsibility | Deadline, input data and acceptance interface |

Any change to area, crop, layout, loads, systems or local responsibilities should record technical impact, price, time and affected drawings before work continues. Verbal approvals are difficult to control. Link the matrix to the contract technical annex.
Civil work, local utilities, unloading and installation responsibilities are frequently interpreted differently and must be listed explicitly.
Yes. Show its price, interfaces and effect on structure, power, water and controls.
No. Drawings show design intent, while the matrix assigns commercial and execution responsibility.
Before contract award, then controlled through formal revisions and approved changes.
