How to manage long-lead items

List every long-lead item in the first week of the job, calculate each one's latest order date by working back from the install date through shipping, fabrication, and submittal approval, then treat those submittals as the most urgent paperwork on the job and expedite each order every week until it ships.

To manage long-lead items, identify them during estimating or the first week after award, set a need-by date for each from the schedule, and subtract shipping, fabrication, and submittal time to get the latest date you can release the order. Put those items on their own tracking log, push their submittals through first, get the owner to approve early release if needed, and confirm fabrication and ship dates every week. The goal is simple: no crew should ever stand around waiting for switchgear, a rooftop unit, or a storefront system.

What counts as long lead depends on the market and the year. Electrical gear, generators, elevators, custom HVAC equipment, structural steel, curtain wall and storefront, specialty doors and hardware, and fire alarm panels show up on many lists. The only reliable way to know is to ask suppliers for current lead times on your specific products, in writing, and to ask again before you order.

Why long-lead items cause so many delays

The fabrication clock usually does not start when you sign the PO. It starts when the supplier has approved shop drawings and a release. That means every day lost in submittal preparation, architect review, or resubmittal comes straight off your schedule. A switchgear package with a long factory lead time can be late before it is ordered if the submittal sits in someone's inbox for three weeks.

How to manage long-lead items step by step

1. Flag them at bid time

During estimating, ask suppliers and subs for lead times along with prices. Mark items that could affect the schedule. If lead times are longer than the bid schedule allows, say so in your bid clarifications rather than discovering it after award.

2. Build a long-lead log in week one

3. Work backward to the latest order date

Need-by date, minus shipping time, minus fabrication lead time, minus submittal review time (including one resubmittal if your architect tends to bounce things), equals the latest release date. If that date is already past, you have a problem to raise today, not next month.

4. Put long-lead submittals first

Ask subs and suppliers for long-lead submittals before anything else. Review them quickly in house, mark them clearly as long lead when sending to the design team, and ask for a review date. Your submittal schedule should show these at the top. How to manage submittals on a construction project covers the wider process.

5. Get early release or owner purchase if needed

If the job is still in design or awaiting permits, ask the owner for written authorization to release long-lead orders early, or for the owner to buy the item directly. Spell out who pays deposits, who carries cancellation risk, and where the material will be stored. Get it in writing before money moves.

6. Release the order and confirm

Issue the purchase order and the release with approved drawings attached. Ask for a written order acknowledgment with the promised ship date. Compare it with your need-by date the same day.

7. Expedite every week

Call or email each long-lead supplier weekly. Ask for fabrication status, any changes to the ship date, and carrier details once shipping is arranged. Record who said what and when. A slipping date found eight weeks out leaves options; one found at the loading dock does not.

8. Plan the delivery and storage

Large equipment needs a crane, a rigging plan, a clear path, or a protected storage spot. Coordinate the delivery date with the site logistics plan. If the item arrives early, check your contract to see whether it can be billed as stored materials and what documentation and insurance that requires.

Worked example: switchgear on a medical office building

Here is an illustration. A GC is building a two-story medical office with permanent power needed in week 26. The electrical sub's distributor quotes a long factory lead time after approved shop drawings, plus about one week of shipping. The GC's PM works backward:

  • Need-by on site: week 24 (two weeks of buffer before energizing).
  • Shipping: one week, so it must ship by week 23.
  • Factory lead time from release: in this example, 16 weeks, so release by week 7.
  • Submittal prep and review with one possible resubmittal: five weeks, so the submittal must go in by week 2.

The contract was signed in week 0, so the electrical submittal is due almost immediately. The PM tells the sub at the kickoff meeting, gets the submittal in week 2, and asks the architect for a 10-day review. It comes back with minor comments in week 4, the sub resubmits, and approval lands in week 6. The release goes out in week 6, one week early. Weekly expediting shows the factory slipping by a week in month three; because the buffer exists, the gear still arrives in week 24.

Who should own long-lead tracking

On most commercial jobs, the project manager owns the long-lead log and reviews it in the weekly project meeting, with the superintendent confirming need-by dates and site readiness. Subcontractors report status on their own long-lead equipment to the GC each week, in writing. On smaller companies without a coordinator, the PM may update the log during the Monday expediting calls. What matters is one owner, one log, and a standing agenda item so the list never falls off the radar after the first month.

Mistakes to avoid

  • Trusting old lead times. Ask again before you order; they change.
  • Treating long-lead submittals like any other. They control the schedule. Mark and chase them.
  • Leaving it to the sub. Subs buy their own gear, but the GC owns the schedule. Track their long-lead items too.
  • No written acknowledgment. A verbal ship date is not a commitment.
  • Forgetting the last mile. A crane, a road closure, or a full laydown yard can delay delivery as much as the factory.
  • Not telling the owner early. If a long-lead item threatens the finish date, put it in writing right away. The guide on how to document construction delays for claims explains why timing matters.

Templates and tools that help

Keep the long-lead log alongside a submittal log template and a three-week look-ahead template, so install dates and deliveries stay in sync. How to manage construction procurement and how to track shipments for construction projects cover the rest of the chain.

Smart Business Automator tracks submittals and shipments against each project and can flag items at risk, so a slipping ship date shows up before it hits the schedule. See RFI and submittal tracking automation.

Frequently asked questions

What are long-lead items in construction?

Materials or equipment whose time from order to delivery is long enough to affect the schedule if not ordered early. Common examples include electrical gear, generators, elevators, custom mechanical units, structural steel, and storefront or curtain wall systems.

When should long-lead items be ordered?

By the latest release date you get when you work back from the need-by date through shipping, fabrication, and submittal review. On many jobs that means the first weeks after award, or earlier with owner authorization.

Can an owner buy long-lead items before the contractor is hired?

Yes, owners sometimes pre-purchase equipment and assign it to the contractor later. The contract should state who is responsible for coordination, receiving, storage, warranty, and installation.

Who tracks long-lead items, the GC or the subcontractor?

Usually the subcontractor buys its own equipment, but the GC should track every long-lead item on one log because the GC owns the overall schedule.
