How early should you quote equipment before a plant breaks ground?
If you're in capital equipment sales and you wait for the RFP to hit your inbox, you're quoting against someone who already walked the site.
The honest answer to "how early" is: before the general contractor has a signed notice to proceed. Not after. By the time a plant owner issues a formal request for equipment quotes, the civil package is usually awarded, the pad grading is scheduled, and your competitor's regional rep has probably already had a lunch with the plant manager. The quote window that actually matters opens the week earthworks start, which is months before anyone sends you a spec sheet.
Where the quote has to land on the build schedule
Walk a typical greenfield build backward from the ribbon-cutting and the quoting math gets obvious fast.
Commissioning and equipment install sit at the tail end, usually 60 to 90 days before startup. Before that you've got structural steel and building envelope, often 4 to 6 months. Before that, foundations and slab, another 2 to 3 months. Before any of that, site prep: clearing, grading, pad work, access roads.
If your equipment has a fabrication lead time of 6 to 9 months (which is normal for anything custom-built, a conveyor system, a baghouse, a process skid) and install has to happen before structural close-in, you need a signed PO roughly a year ahead of commissioning. Work that back further to account for the buyer's internal approval cycle, budget sign-off, and the 2 to 3 competing quotes they're required to collect, and your quote needs to be in their hands while the site is still raw dirt. Not a rendering. Dirt.
Most OEM reps treat the plant not being built yet as a reason to sit on their hands. That's backward. The window before the plant exists is the only one where your quote isn't competing against three others the buyer already collected.
What happens if you wait for the RFP
By the time a formal RFP goes out, the buyer usually already has a shortlist. Someone on their team, often a project engineer or the EPC's procurement lead, has already called two or three OEMs for budgetary numbers. Those informal conversations happen during site prep and foundation work, long before procurement posts anything. If your first contact with the account is the RFP, you're the fourth call, not the first.
There's also a scheduling trap. Standard, off-the-shelf equipment might have a 60 to 120 day lead time and can slot in late. Anything requiring engineering review, custom fabrication, or a dedicated production slot does not have that flexibility. If the buyer only reaches out once they're ready to buy, and your lead time doesn't fit their remaining schedule, you lose the deal on timing alone, regardless of price or spec match.
The lead-time math most reps get wrong
Reps tend to measure lead time from "quote accepted" to "equipment delivered." That's the wrong clock. The clock that matters is from "site breaks ground" to "equipment must be on-site for install," minus your fabrication and shipping time, minus the buyer's internal approval cycle. Run that math on a real job and the result is almost always the same: you needed to be in front of the buyer before they had a project name for it.
Most regional reps already know this lead-time math cold. What's harder is finding out a greenfield project exists while it's still earthworks and grading, not after the building is framed and the buyer's procurement team starts calling vendors. Permit filings lag, press releases lag further, and by the time a site shows up on an industry list it's usually mid-construction.
A monthly pass over your territory's industrial zones catches that first break of ground, the cleared pad, the new access road, before any of that information makes it into a press release. That's the entire premise behind Greenfield Watch: flag the site the month it starts, not the month it opens, so the quote goes out while there's still time for it to matter.
If your territory has a plant going up right now and you don't know it yet, that's the gap worth closing first.
