How long between site grading and equipment installation at a new plant?
Most owners run somewhere between nine and eighteen months from first dirt move to first machine bolted down. Tilt-up concrete runs longer than a pre-engineered metal building. A full process plant with heavy foundations and a lot of underground utility work runs longer still. If you've been quoting equipment for a while, you already know the honest answer is "it depends," but the phases in between are predictable enough to plan around, and that's what actually matters for a sales calendar.
The phases between grading and install
Earthwork comes first: clearing, mass grading, pad preparation. On a straightforward site this takes four to ten weeks depending on soil conditions and how much cut-and-fill the grading plan calls for. This is also the stage almost nobody outside the civil contractor sees, which is the whole problem for anyone trying to quote early.
After the pad is graded and compacted, foundations go in. Slab-on-grade for a light manufacturing building can move fast, two to six weeks for footings and slab pours. A tilt-up building adds panel casting and tilt-up crane days. A plant with deep foundations for heavy process equipment, kilns, presses, large vessels, can add months here alone.
Shell erection follows: structural steel or tilt-up panels go up, the building gets "dry-in" (roof and walls weathertight), and MEP rough-in starts, electrical, plumbing, HVAC ductwork, process piping. This phase typically runs eight to sixteen weeks depending on building size and how much of the rough-in is happening in parallel with the shell going up.
Only after rough-in is far enough along does equipment installation really start in earnest, though some OEMs do begin rigging in heavy equipment before walls are fully closed if the crane access window requires it. Final equipment hookup, commissioning, and certificate of occupancy typically land somewhere in the final one to three months before the plant opens.
Stack those phases end to end and you get the nine-to-eighteen-month range. Stack a permitting delay, a utility hookup delay, or a steel lead time problem on top, and that range stretches further. None of that is secret information, any GC on the job could walk you through it. But nobody flags the day grading starts, so most reps don't hear about the project until someone's already driving the forklift fleet off a flatbed.
Why the pad-to-production-line window is the one that matters for quoting
Your sales cycle, submittal review, spec match, quote revisions, PO, lead time on your own equipment, probably needs three to six months of runway before the plant needs the machine on the floor. If you find out about the project at groundbreaking announcements or permit filings that hit the trade press, you're already working with a shortened window, and a competitor who had eyes on the site earlier is working the account while you're still drafting a proposal.
The month grading starts is the month a site stops being a rumor and starts being a real capital project with a real schedule. Owners don't always announce it. County permit records lag. Local press picks up ribbon cuttings, not the week the dozers showed up. If your territory covers more than a couple of counties, watching every parcel by hand, driving past, checking permit portals, calling contacts, isn't something one rep can keep up with across a whole region.
That's the gap Greenfield Watch is built to close. A monthly pass over your watch area flags cleared land, graded pads, and new access roads the month earthworks start, with a dated alert and location, so your quote can go out while the site's still being built instead of after someone else's fleet is already parked on it.
If your territory has more greenfield activity than you can track by driving past it, it might be worth putting Greenfield Watch on your next watch area.
