Greenhouse tender technical specification template
Last reviewed:
Short answer: a usable greenhouse specification states performance, not brands. For each lot, write the design conditions (wind, rain, temperature, humidity), the minimum performance, the documents bidders must submit and the test that proves acceptance. Split the work into lots suppliers can price separately — structure and covering, cooling and ventilation, irrigation and fertigation, water harvesting and storage, climate control, post-harvest and O&M — so offers can be compared line by line.
Specification by lot
| Lot | Performance to specify | Bidder must submit | Acceptance test |
|---|---|---|---|
| Structure | Design wind speed and storm category, rain and crop loads, gutter height, span, corrosion protection (galvanising class) | Structural calculations signed by an engineer, foundation design, materials certificates | Dimensional check, bolt torque and anchoring inspection |
| Covering and screens | Film thickness and life, light transmission, diffusion, UV stability; insect-net mesh; shade screen percentage | Manufacturer data sheets and warranty terms | Visual inspection, tension and sealing check |
| Ventilation and cooling | Indoor design temperature and humidity for the crop on the design day; airflow per m²; pad area and efficiency or fogging capacity | Cooling calculation, fan curves, pad data | Airflow and temperature-drop test on a hot day |
| Irrigation and fertigation | Emitter flow and spacing, uniformity target, number of nutrient channels, EC/pH control range, filtration grade | Hydraulic design, dosing unit data, filtration sizing | Distribution-uniformity test, EC/pH dosing accuracy test |
| Water harvesting and storage | Catchment area, storage volume for peak-day demand and dry spells, lining, treatment | Water balance and storage calculation | Leak test, inflow/outflow check |
| Climate control | Sensors (temperature, humidity, radiation), control of vents, screens, fans and irrigation; alarms; data logging | Control philosophy, I/O list, software licence terms | Site acceptance test of every control loop |
| Post-harvest | Packing area layout, washing, grading, cold storage temperature and capacity | Layout, equipment data, refrigeration calculation | Pull-down test of cold room |
| Training, O&M and spares | Training days, O&M manuals, spare-part list for the liability period, local service response time | Training plan, spare list with prices | Training attendance record, spares delivered |

Questions buyers ask
What should a greenhouse tender technical specification include?
Design conditions, minimum performance per lot, required bidder documents and acceptance tests, plus training, O&M and spare parts. Avoid brand names; specify performance so several suppliers can comply.
How do I compare greenhouse bids fairly?
Make every bidder price the same lots and quantities, normalise exclusions (transport, duties, installation, spares) and score technical compliance before price.
Can this template be used for an RFQ to private suppliers?
Yes. The same lot structure works for an RFQ. Our RFQ builder sends one written scope to qualified suppliers; we do not prepare official tender documents for public bodies.
