The short answer
Create the matrix by deliverable, not by company name alone. For every survey, calculation, drawing, permit, material, utility, shipment, installation task, inspection, test, training item, and handover record, identify who prepares it, who reviews it, who approves or accepts it, who supplies inputs, and when it is due. Add the physical and information interface, governing document, acceptance evidence, and escalation path. One party must own completion even when several parties contribute.
A statement that foundations are by the owner does not say who provides column reactions, anchor layouts, tolerances, survey benchmarks, grout requirements, drainage levels, embedment details, or final inspection. The matrix breaks a broad package into deliverables that can actually be coordinated.
Responsibility should follow the project sequence. The party that needs information must know when it will arrive, and the party producing it must know the required format and acceptance criteria. A correct document delivered after procurement or concrete placement is still a project failure. Add early-warning dates before each final due date so a missing input can be escalated while recovery is still possible.
This guide supports procurement and project coordination. Project-specific values, contract terms, legal duties, and safety decisions remain with the buyer, qualified designers, logistics providers, contractors, insurers, and authorities responsible for the work.
Information to fix before requesting a firm offer
| Input group | Record | Decision supported |
|---|---|---|
| Design and approvals | Survey, geotechnical data, climate basis, codes, structural calculations, foundations, drainage, utilities, fire and life safety, environmental approvals, professional seals, and design changes. | Allocates both input and approval responsibility. |
| Supply and local procurement | Structure, cladding, screens, equipment, controls, cables, pipes, fasteners, consumables, tools, lifting accessories, temporary works, and approved substitutions. | Prevents small but essential items from falling between packages. |
| Logistics and site | Export documents, freight, insurance, customs, permits, unloading, inspection, laydown, weather protection, security, access, welfare, temporary power, and waste. | Defines custody and readiness from factory to erection point. |
| Installation and integration | Setting out, foundations, anchors, erection, cladding, mechanical work, electrical work, network, water, drainage, fuel, controls, labeling, testing support, and correction. | Assigns every connection between greenhouse and local infrastructure. |
| Acceptance and operation | Inspection plans, commissioning scripts, instruments, witnesses, utilities, crop-free test conditions, training, manuals, as-built records, spares, punch closure, warranty notice, and service response. | Defines how completion becomes usable operation. |
Mark every unknown as provisional and give it an owner and closure date. If a supplier proposes an alternative, require the offer to identify the changed assumption and its effect on scope, interfaces, performance, delivery, site work, risk, and price.
A practical review sequence
1. Start with the work breakdown and interfaces
List systems and project stages, then identify where information, materials, power, water, drainage, control signals, physical supports, custody, and approval pass from one party to another. Give each interface an identifier that appears in drawings and meeting actions.
2. Assign producer and acceptor
For each deliverable, name one party that produces the result and one party that confirms it meets the agreed requirement. Contributors and consultees may be added, but shared responsibility without a lead usually becomes no responsibility.
3. Add timing and prerequisites
Record the required date, predecessor input, review duration, approval gate, and effect of delay. Link design reactions to foundation dates, utility data to equipment selection, packing lists to customs preparation, and training to system availability.
4. Maintain the matrix through change
Review it at design, procurement, pre-shipment, pre-installation, commissioning, and handover meetings. When scope changes, update the matrix and affected contract documents together. Closed actions should point to evidence rather than a verbal status.
Keep decisions in a controlled clarification register. When a drawing, bill of materials, shipment plan, or work method changes, the team can trace which quotation line, interface, delivery milestone, and acceptance record also needs revision.
Divide responsibilities at the interfaces
Owner and grower
Provide crop, site, utilities, operating priorities, acceptable risk, local resources, permits, insurance requirements, and approval authority.
Greenhouse supplier
Define the contracted design, supply, documents, packing, supervision, testing, training, exclusions, and interface data.
Local specialists
Confirm local codes, civil works, electrical and water connections, import rules, lifting, safety, labor, and professional approvals.
Project and logistics team
Control dates, changes, documents, inspections, transport, receipt, storage, installation readiness, punch items, and evidence.
A named party should be responsible for each deliverable, and another named party should accept it. Words such as complete, standard, by others, or site preparation are not adequate where two contracts meet.
Common failures to close before award
| Failure | Why it matters and what to do |
|---|---|
| RACI letters replace deliverables | A colored cell does not define what must be produced. Add a clear output, format, due date, interface, and acceptance evidence. |
| By others has no named owner | Replace the phrase with the actual owner, local contractor, consultant, utility, broker, or supplier and confirm that party has accepted the duty. |
| Design and installation are separated incorrectly | The installer needs tolerances, methods, inspection points, and approved changes. Allocate feedback and as-built responsibility as well as original design. |
| The matrix stops at shipment | International supply still needs customs, receipt, storage, erection, connections, tests, training, defect correction, documents, and warranty communication. |
Record accepted deviations in the contract documents. A verbal promise or meeting note should be transferred to the drawing, schedule, specification, packing list, responsibility matrix, or test record that governs the work.
Define acceptance and evidence early
Agree which documents require approval, which components require factory checks, what will be inspected at dispatch and receipt, and what must be demonstrated after installation. State witnesses, notice periods, instruments, sample size, tolerances, photo requirements, nonconformance handling, retesting, and record format.
Connect supply and delivery checks to the greenhouse commissioning checklist. Use the handover document and spare-parts schedule to confirm that manuals, settings, certificates, lists, tools, and agreed spares arrive with the correct shipment and remain identifiable through installation.
Payment milestones should refer to objective deliverables rather than calendar dates alone. The commercial contract and applicable law must be reviewed by qualified advisers, but the technical team can reduce ambiguity by defining the evidence that shows each deliverable is complete.
Questions the buyer should answer
Who supplies and accepts every design input? Who confirms local code and permit requirements? Who purchases interface materials and consumables? Who owns goods at each transport stage? Who checks shortages and damage? Who provides cranes, tools, temporary services, safety supervision, and skilled labor? Who energizes equipment? Who writes, witnesses, and accepts tests? Who closes punch items and keeps the final records?
Frequently asked questions
Is a responsibility matrix the same as a contract?
No. It is a coordination tool and should be consistent with the executed contracts. If it reveals a gap or conflict, the relevant contract documents need formal clarification.
Can two parties be responsible for one task?
Several parties can contribute, but one lead should own completion and one named party should accept the output. Otherwise decisions and delays become difficult to control.
How detailed should the matrix be?
Detailed enough to expose interfaces that can stop work, cause rework, affect safety, delay approval, or prevent acceptance. Group routine items only when their owner and evidence are genuinely the same.
Who should maintain it?
The project manager or designated interface manager should control the current version, while each organization confirms its assigned duties and dates.
