Procurement starts before a purchase order.
Major equipment can influence how a building is designed and when it can become operational. Waiting until construction starts to discuss procurement leaves fewer options. Start by identifying the equipment that could control the sequence of work.
Work backward from installation.
For each significant item, map the installation date, delivery needs, manufacturing time, submittal review, and design information required to place an order. Verify these steps with the relevant suppliers and project team. Lead times are project-specific and can change.
Connect the item to the building.
An equipment selection may affect electrical capacity, structural support, cooling, access, or clearances. A procurement log is most useful when it connects these dependencies to the people responsible for resolving them.
Track decisions as well as deliveries.
A shipment date does not tell the whole story. Track approved submittals, release dates, confirmed vendor commitments, and open decisions. When something changes, review its effect on related work and update the team.
Keep the owner involved.
Early purchases can create financial and design commitments. The owner should understand the scope, assumptions, storage arrangements, and consequences of later changes before authorizing a release.
