Delays on long lead items are usually decided months before anyone notices them. A switchgear panel, a chiller, a lift package or a facade system can take months to manufacture and ship. If the order goes out late, no amount of site effort recovers that time.
Yet on many projects, long lead items are bought like any other package. The order waits for approved drawings, then for three quotes, then for a budget sign-off. By the time the PO is issued, the delivery date already sits behind the installation date on the programme.
The site team finds out when the item does not arrive. The cause was in the planning stage.
Long lead items are not always the most expensive packages. They are the ones with manufacturing slots, specialist approvals, or import routes the contractor does not control. Electrical switchgear, generators, lifts, specialist glazing and engineered steel are common examples on contractor projects in the region.
Many of them also sit on the critical path. A late chiller does not just delay its own installation. It holds up testing and commissioning, which holds up handover, which triggers delay exposure with the client. The cost of a missed order date is rarely the item itself.
Lead times are not fixed either. They move with factory backlogs, shipping routes and approval cycles. A quote that promised twelve weeks in January can mean eighteen by the time the order is placed. We covered how quickly that can shift in our piece on construction procurement and supply chain breakdowns.
The planning discipline is well established. PMI research on schedule improvement through procurement strategies treats identifying critical long lead equipment as an integral part of front-end planning, not a task left for the construction phase. The same paper cites industry studies estimating that 10 to 12 percent of construction labour cost could be saved if materials and equipment were available when needed.
In practice, that means working backwards. Take the installation date from the programme, subtract delivery, manufacturing, submittal approval and procurement time, and the result is the date the order must go out. For some packages that date falls before the design is fully complete, which is exactly why it gets missed.
A contractor who builds that backwards schedule at the start of the project knows which approvals to chase first. One who does not discovers it package by package.
The backwards schedule also changes the conversation with the consultant. A submittal flagged as blocking a long lead order gets reviewed faster than one sitting in a general queue, because everyone can see what waiting will cost the programme.
Most contractors do track long lead items, but in a spreadsheet owned by one person. The programme lives in the planning software. Submittal status lives with the document controller. Supplier commitments live in the procurement manager’s inbox. Nobody sees all three together.
When a drawing approval slips by two weeks, nothing tells procurement that the order date has moved. When a supplier extends the lead time, nothing tells the planner. Each change is small, and each is visible to only one person. It is the same admin layer behind why your procurement manager spends more time on emails than decisions.
The fix is connecting the three records. Each long lead item carries its required-on-site date, its order-by date, its submittal status and its supplier commitment in one place. When any of them moves, the others update and the people who need to act are told.
That is what construction ERP does for procurement planning. Mismar works with contractors across UAE and KSA to flag long lead items before the order date passes, not after the delivery is missed. If your long lead tracking lives in one person’s spreadsheet, let’s get on a call.
