Greenhouse Scope of Supply and Exclusions Checklist

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.

Why Scope Gaps Create Cost Overruns

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.

1. Engineering and Documents

  • Site survey, soil report and local design criteria

  • General layout, foundation reactions and structural calculations

  • Shop drawings, equipment data sheets and electrical diagrams

  • Bill of quantities, packing list and spare-parts list

  • Languages, formats, revision process and approval deadlines

Use the drawing approval checklist to define review control.

2. Civil and Site Work

  • Clearing, grading, roads and drainage

  • Foundations, concrete, anchor installation and tolerances

  • Water storage, equipment rooms, packhouse and cold room

  • Electrical transformer, generator, grounding and site cabling

  • Fencing, security, waste handling and temporary works

3. Greenhouse and Crop Systems

  • Structure, covering, aluminum, fasteners, doors and gutters

  • Roof and side vents, insect net, shade and thermal screens

  • Fans, cooling pads, fogging, heating and climate controls

  • Irrigation, fertigation, water treatment and drainage

  • Hydroponic channels, gutters, benches, crop support and lighting

Require model numbers, material specifications and quantities. Product-category names alone are not sufficient.

4. Logistics and Installation

  • Factory packing, container loading and export documents

  • Trade term, freight, insurance and destination charges

  • Unloading, storage, cranes, forklifts, tools and scaffolding

  • Local labor, skilled labor, travel and accommodation

  • Installation supervision, safety management and quality checks

Review the installation responsibility guide before assigning local labor.

5. Commissioning and Handover

  • Mechanical inspection, electrical testing and water flushing

  • Control sequences, alarms, manual modes and backup operation

  • Training agenda, operating manuals and maintenance schedule

  • Acceptance tests, punch list and completion documents

  • Warranty start, exclusions, response process and spare parts

Change-Control Rule

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.

Frequently Asked Questions

What is the most common greenhouse exclusion?

Civil work, local utilities, unloading and installation responsibilities are frequently interpreted differently and must be listed explicitly.

Should optional equipment be in the same matrix?

Yes. Show its price, interfaces and effect on structure, power, water and controls.

Can drawings replace a responsibility matrix?

No. Drawings show design intent, while the matrix assigns commercial and execution responsibility.

When should the matrix be frozen?

Before contract award, then controlled through formal revisions and approved changes.
