A procurement schedule records when design freedom ends. Delivery date is only the final milestone; approval, shop drawings, manufacturing, shipping, storage and installation all begin earlier.
Track the decision date
Long-lead items should identify the last date for dimensions, finishes and interfaces to change. That date depends on a complete shop-drawing review, not a placeholder approval.
Where quality depends on a prototype, add the build, review and correction cycle from the joinery mock-up process.
Link every item to predecessor work
A banquette cannot install before power and floor finishes; its exact section follows the fixed-seating coordination test. Ceiling equipment depends on the resolved map explained in the reflected ceiling plan guide.
Define substitution before delay
Record who can approve alternatives and which performance criteria cannot change. Finally, transfer warranties, spares and approved data into a handover manual operators will use.
