How long does a commercial greenhouse take from order to handover?
Treat the programme as four sequential blocks: specification and tendering, contract and design freeze, manufacture and shipment, then civil works, installation and commissioning. Each block has its own critical path, and the total depends on structure class, whether glass or film is used, the origin of the equipment, permitting, and how ready the site is. Suppliers can only commit to a date once the specification is frozen and the deposit terms are met, so a schedule quoted before design freeze is an estimate, not a commitment.
What actually drives the answer
Design freeze is the real start date. Every change to gutter height, covered area, screen configuration or climate equipment after freeze re-opens engineering and pushes manufacturing slots.
Manufacturing slots are allocated, not instant. Structure steel, glass, screens, controllers and irrigation heads are frequently produced by different plants with different queues, and the project moves at the pace of the slowest one.
Shipping is a schedule item in its own right: container availability, breakbulk sailings, port congestion and customs clearance each carry their own variance and belong in the programme explicitly.
Civil works are usually the owner's scope. Access roads, levelling, foundations, water connection and power connection must be finished before installation crews arrive, otherwise crews stand idle at the owner's cost.
Grid connection and permitting are the most common silent delays because they sit with third parties. Start both in parallel with tendering rather than after contract signature.
Variables that change the answer
- Structure class and covering type
- Country of manufacture and shipping route
- Permitting and grid-connection timelines
- Site readiness and civil works scope
- Payment milestones and deposit timing
- Phasing of the covered area
Evidence a supplier needs before quoting
- Frozen technical specification and covered area
- Confirmed site access, levelling status and utility connections
- Target planting or offtake date
- Permit status from the relevant local authority
What this answer does not settle
- This is a programme structure, not a delivery guarantee. Only the contracted supplier can commit to dates for your scope and origin.
- It does not account for force majeure, port disruption or local labour availability.
Responsibility
- Professional review:
- Project manager and the contracted supplier's engineering team
- Delivered by:
- Greenhouse manufacturer, integrator or turnkey EPC contractor
- Feeds RFQ section:
- Programme, delivery and installation
