How far in advance should you book a concrete pump?

When the pour goes on the schedule — not the week of. In pour season a good pump outfit’s calendar fills days ahead, and the morning slots go first. Booking early costs nothing (you can move it); booking late means taking whatever boom and whatever start time is left, or losing the pour date the GC already built around.

What does the pump company need to know when you book?

Where the pump sets up and what it has to reach over — that drives boom size more than yardage does. Then: overhead power lines anywhere near the setup or the reach, the start time, estimated yards and your target rate, the mix (they’ll want to know it pumps), whether line or system needs beyond the boom, and the site contact’s cell. A dispatcher who asks none of these questions is telling you something.

When should the pump arrive relative to the first truck?

Comfortably first — commonly about an hour before the first load, enough to set outriggers, run the boom out, and prime the line. The first truck should be timed to when the pump is ready to take concrete, not to when the crew clocks in. A pump setting up while a loaded mixer idles beside it is the most expensive way to spend the 90-minute clock.

What size boom do you need?

It’s a site question, not a volume question. The boom has to reach from where the outriggers can legally and physically sit to the farthest point of the placement — over the formwork, the scaffold, or the building edge in between — while keeping required clearance from power lines. Give dispatch the setup spot and the far corner; sizing the boom is their job, and they’re better at it than a guess from the office.

What happens if the pour cancels after the pump is booked?

Inside the cancel window, most pump outfits charge something — a cancellation or minimum fee, sometimes travel if the unit already rolled. Ask for the cancel cutoff when you book and write it on the pour. It’s one more reason the go/no-go call gets made at 4–6 AM: early enough to stop the pump as well as the trucks.

Pump Truck Scheduling: How Concrete Subs Book the Boom

Of everything rolling toward a pour, the pump is the piece you can least improvise. Ready-mix can add a truck; the crew can stay an hour; but if the boom isn’t booked, isn’t big enough, or isn’t set up when the first drum arrives, the whole morning re-prices itself while you watch. Pump scheduling is a short discipline — book early, brief dispatch properly, sequence the arrivals — and it’s worth doing in exactly that order.

Book the pump when you book the pour

The moment a pour lands on the schedule with a date, the pump call happens — not the week of. In season, good outfits are spoken for days ahead and the early-morning slots go first; wait and you’re choosing between somebody’s third-choice boom and moving a date the GC has already sequenced trades around. Booking early is free insurance: a booked pump can be moved, but a busy Saturday can’t be conjured. While you’re on the phone, get two numbers and write both on the pour: the arrival time and the cancel cutoff.

Brief dispatch like it matters — because the boom is a site question

Yardage is the least interesting thing you’ll tell them. What sizes the unit is geometry: where the outriggers can sit, what the boom reaches over — formwork, scaffold, a building edge — and how far the farthest point of the placement is from that setup spot. And before any of it: overhead power lines, the first question every competent dispatcher asks, because clearance rules around energized lines are non-negotiable and re-positioning a pump mid-morning costs more than answering honestly on the phone. Add the start time, the target rate, the mix (say it’s a pump mix), any line or system work beyond the boom, and the cell number of the person who’ll actually be standing at the pour.

The timing chain: pump, then trucks, then crew math

The sequence that wastes nothing: the pump arrives about an hour before the first truck — outriggers down, boom out, line primed — and the first load is timed to pump-ready, not to the crew’s start time. From there the pour runs at the pump’s pace: a boom sustaining 70–90 yards an hour will drain a 10-yard drum in minutes, so the truck rotation — not the machine — sets the day’s real rate. That’s an ordering problem, and it has its own guide: spacing tightened to the pump’s appetite, a first truck that lands on a pump that’s ready, and a dispatcher who hears about drift early. A loaded mixer idling beside a pump that’s still setting up is both clocks burning at once.

Cancel windows: the pump belongs in the go/no-go

Pumps bill like the specialized equipment they are — minimums, travel, and a cancellation charge inside the cutoff you asked about when you booked. Which means the 4–6 AM go/no-go call isn’t just about stopping trucks: it has to beat the pump’s rolling time too. A no-go decided at 5 that reaches the pump at 7:30 bought a boom standing in front of a pour that isn’t happening — the most avoidable invoice in concrete.

Three vendors, one change, one message

Here’s the quiet failure mode: the pour moves a day, the crew hears, the plant hears — and the pump hears nothing, because the schedule lives in a spreadsheet and the news travels by whoever-remembers. On the Place & Finish board the pump operator rides on the pour card with the plant and the GC, so when the pour is confirmed, moved, or canceled, one click reaches all of them at once — reason, old date, new date. The booking discipline is yours. Making sure a change reaches every vendor you booked — that’s what the board is for.

Book it early, brief it once, move it in one click

A pump morning that goes right is quiet: boom set before the first drum, trucks landing on a machine that’s ready, and every change reaching every vendor before anyone rolls.
