TURNKEY PROJECTS
Turnkey greenhouse projects: scope, tendering and comparable offers
Turnkey means different things to different contractors, and the gap is where budgets break. Define the scope split before tendering, then compare offers that all answer the same question about who delivers civil works, utilities, commissioning and training.
SeedMatchGroup helps buyers source greenhouse equipment, agricultural seeds, fertilizers, irrigation systems, pumps, solar systems, drones, cooling systems and complete agriculture project suppliers worldwide.
SeedMatchGroup is supplier-neutral and helps buyers compare greenhouse, seed, fertilizer, irrigation and agriculture project suppliers worldwide. It does not manufacture, distribute or sell equipment or inputs.
What is included in a turnkey greenhouse project?
A turnkey greenhouse project typically covers design and structural calculation, the structure and covering, climate and irrigation systems, growing system, electrical and control installation, installation supervision or full installation, commissioning and operator training. What is frequently excluded — and must be checked in writing — is land preparation, foundations, water source development, grid connection, import duties, local permits and post-harvest facilities.
Product and supplier categories
Design & engineering
Layout, structural calculation, climate design and utility load definition.
Civil & foundations
Levelling, drainage, concrete works and access — often excluded from supplier scope.
Structure & systems
Frame, covering, climate, irrigation, growing system and electrical installation.
Utilities
Water source, storage, power supply, generators and solar hybrid options.
Commissioning
Testing, calibration, handover documentation and operator training.
Post-harvest
Packhouse, cold room and grading capacity planned with the production build.

For consultants and advisors
Specifying a greenhouse for a client project?
Greenhouse consultants, horticultural engineers and agriculture EPC advisors use us to shortlist structure, climate-control and irrigation suppliers, prepare the RFQ pack and normalise the quotes that come back. You stay client-facing throughout.
Scoping a turnkey greenhouse project
A turnkey greenhouse contract bundles design, structure, climate, irrigation, controls, installation and commissioning into one accountable scope. The specification below is what a turnkey contract has to fix before a price means anything.
Structure and covering
- Multi-span polyhouse, Venlo glass or semi-closed structure — chosen from climate, crop and target production window
- Gutter height (4–7 m), bay width and span layout drive climate buffer and internal transport
- Glazing: single or double PE film, polycarbonate or 4 mm horticultural glass with diffusion
- Design wind, snow and seismic loads per local code — the single most common source of quote gaps
Climate, cooling, heating and ventilation
- Roof vents, side vents or forced ventilation with insect netting
- Pad-and-fan, high-pressure fogging or mechanical cooling in hot and arid climates
- Hot water heating, air heaters or geothermal for cold seasons and night setpoints
- Energy and shade screens, dehumidification, and CO₂ enrichment where the crop justifies it
Water, irrigation and fertigation
- Water source, storage volume, filtration and treatment specified before the dosing unit
- Drip lines or drippers per plant, zoning by crop stage and orientation
- Fertigation head with EC/pH control, dosing channels and recipes per growth stage
- Drain water collection, disinfection and recirculation for hydroponic layouts
Controls, energy and handover
- Climate computer with sensors, alarms, logging and remote access
- Connected load, transformer capacity, backup generation and solar option
- Installation, supervision, commissioning, FAT/SAT tests and operator training
- Spare parts pack, warranty terms and a defined maintenance interval
What affects project cost
- Technology level — structure and glazing typically carry 60–70% of hardware cost
- Climate uplift: heating and snow load in cold sites, cooling and shading in hot arid sites
- Site preparation, foundations, access roads and utility connections
- Supplemental lighting, screens and CO₂ where the production plan requires them
- Freight, import duty, local installation labour and currency terms
Information needed to quote
- Site country, coordinates or nearest town, and available land area
- Covered area target (m² or ha) and crop or production model
- Water source, quality analysis if available, and daily availability
- Available electrical capacity and grid reliability
- Target automation level, project stage and budget band
- Required completion date and financing status
What information is required for a greenhouse project quotation?
Site country and climate, covered area, crop, water source and quality, available power, required automation level, target start date and budget band. With those seven inputs a supplier can price a comparable scope; without them every quote is written to a different specification.
