Short answer: Before greenhouse production starts, the buyer and supplier should approve a controlled set of documents covering design criteria, layout, structure, foundations, covering, systems, utilities, interfaces and bill of materials. Every document needs a number, revision, date, status and responsible approver so an old drawing is not used for civil work or manufacturing.
A greenhouse quotation describes a commercial scope, but production and installation depend on coordinated dimensions and interfaces. If the buyer approves only a visual layout, foundation positions, door sizes, crop loads, irrigation rooms or power requirements may remain unresolved. A document register turns scattered emails and chat attachments into one agreed technical baseline.
| Register field | Purpose |
|---|---|
| Document number and title | Give every drawing, schedule and calculation a unique reference. |
| Revision and issue date | Separate current information from superseded files. |
| Status | Mark draft, for review, approved, approved with comments or as-built. |
| Prepared, checked and approved by | Clarify responsibility and authorization. |
| Comments and close-out | Track questions until each issue is resolved. |
The design basis should identify project location, greenhouse dimensions, covering, crop and suspended loads, locally confirmed wind and snow criteria, rain and drainage assumptions, temperature and humidity inputs and applicable requirements. The supplier should distinguish buyer-provided data from supplier assumptions. Local engineers should verify soil, foundations and regulatory requirements where required.
Approve the site layout, greenhouse orientation, spans, bays, heights, doors, service rooms, drainage routes and clearances. Interface drawings should show foundation grids, anchor details, utility entry points, tank and pump locations, electrical panels, equipment pads and connections to local works. Dimensions should be referenced from stable grid lines rather than approximate site features.
Request general arrangement drawings, member schedules, bracing, connections, vent details, gutters, downpipes, covering attachment and approved crop-wire or equipment-support points. The contract should state which structural calculations, material records or inspection documents are required. Do not assume an unspecified certificate is included.
Ventilation, shading, cooling and heating layouts
Irrigation, fertigation, filtration and water-treatment diagrams
Hydroponic channel, substrate, tank, drain and recirculation layouts
Electrical equipment schedule and single-line diagram within scope
Control input-output list, sensor positions and operating sequence
Equipment data sheets and spare-parts schedule
The bill of materials should match the approved drawings and quotation revision. Check quantities, descriptions, material specifications, equipment models, supplied accessories and exclusions. Where installation consumables or local materials are not included, identify them before shipping. Changes after approval should use a written change record with cost, schedule and technical impact.
Assign one buyer coordinator and one supplier coordinator. Consolidate comments into a single marked document, set a response date and require a revised issue that closes each comment. Approval should mean the buyer accepts the documented configuration for the stated purpose; it should not remove the supplier's responsibility for its contractual design and manufacturing scope.
Foundation and underground utility work should use approved-for-construction information. Confirm the drawing revision at the site, check dimensions against survey control and record any discrepancy before concrete is poured. Keep superseded drawings clearly separated from active site files.
Limited preparation may be possible, but mass production before key dimensions, systems and interfaces are approved creates mismatch and change risk.
The buyer should appoint an authorized coordinator and use qualified local professionals for soil, foundations, regulations and utilities where required.
It means the document can proceed only with the listed comments incorporated or resolved according to the agreed workflow.
Keep them as controlled history, but mark them superseded and prevent their use for current production or construction.
