Owner-supplied or contractor-supplied: who buys, receives, installs and warrants each item
The owner's fermentation tanks are due next week. The mechanical trade expects the owner to arrange unloading, while the owner assumes the contractor has included it. The chiller supplier's startup visit is also missing from everyone's scope list.
Make an item-by-item responsibility table covering procurement, delivery, unloading, protection, installation, connections, startup and warranty handling. Agree the boundaries with the authorized owner and contractor representatives before shipment. Separate doing a task from paying for it and approving its method. The schedule can give an item a delivery date while leaving these scope obligations unresolved; this table closes those particular gaps.
Follow each item from purchase to service
- Identify the exact item and supply basis. Record the approved description, supplier and purchasing party. List required information and its release owner. Confirm who checks compatibility with the project requirements instead of assuming an owner purchase removes that coordination need.
- Assign delivery and receipt. Identify destination, receiver, booking contact and what condition or quantity record is required. State who resolves shortages and delivery discrepancies through the agreed commercial process. Align these responsibilities with the actual purchase and project agreements.
- Resolve unloading and movement. Name the party arranging a qualified handling plan, resources and workface route. Record the cost responsibility separately. This table should expose the need for technical planning without prescribing a lift, machine or capacity from the item's weight alone.
- Set storage and protection boundaries. Agree the location, receiving date and party maintaining the item's condition. Identify whether early arrival needs a revised delivery or an approved storage arrangement. Record the handoff between responsibility stages.
- Separate installation, connections and startup. Identify the trade's scope and the supplier's required participation from the approved project documents. Name who books each stage, provides inputs and retains its completion record. A supply-only label does not answer every interface question.
- Confirm service and warranty communication. Have the commercial parties agree who handles reports, supplier contact and any disputed shortage or damage. Check the table against the agreements, obtain authorized acceptance and review open responsibilities as delivery approaches.
Common mistakes
- Using owner supplied as though it also assigns receipt and installation.
- Naming a task owner without settling its payment basis.
- Leaving warranty communication until a problem occurs after handover.
Checklist
Before confirming shipment
- Item and purchasing party identified.
- Receiver and discrepancy process.
- Handling review and cost owner.
- Storage and protection handoffs.
- Installation, connection and startup parties.
- Warranty contact and unresolved terms.
Check your understanding
The owner bought the item and your trade installs it. Does that settle who unloads and protects it?
