Managing the 10 to 40 Yard Size Mix on Each Roll-Off Truck's Day

Ten, fifteen, twenty, thirty, forty. Five sizes, and every one of them changes how a roll-off day runs. A truck that alternates between a 10 and a 40 all day spends half its time in the yard. A truck that runs all 20s can chain swap after swap with barely a stop.

Landfill runs, the topic of Planning Landfill and Transfer Station Runs Between Roll-Off Stops, shape where a truck goes. Size shapes what it can carry when it gets there. This guide covers planning the size mix on each truck's day.

Why Size Changes the Route

A delivery requires the truck to have the right empty on board. A swap requires the right empty going in and handles whatever full can is coming out. If the next job needs a different size than what the truck has, the truck goes to the yard first. Each of those yard stops is a detour.

Grouping jobs by size on a truck's day cuts the detours. Two 20-yard swaps back to back mean the empty from the first dump can, in some setups, go straight to the second site. A 20-yard pickup followed by a 20-yard delivery lets the driver dump the full can and take the now-empty 20 to the delivery, if your operation works that way and the can is in good shape.

The cost of a yard stop depends on where the yard is. If your yard sits in the middle of your service area, a stop is a minor detour. If it sits on one edge, every unplanned yard stop can cost half an hour or more. Knowing that number for your own operation tells you how hard to work at grouping sizes.

Know Which Trucks Handle Which Sizes

Not every truck in every fleet runs every size well. A lighter truck might be best on 10s and 15s. A heavier one might be the only one you trust with full 40s or with 20s full of concrete. Those limits are about your equipment, so set them yourself and stick to them.

When you assign a driver and truck in one step, the truck is on the job and the size is on the job, so the board shows you whether you have put a 40 on a truck that should not carry it. Make checking that a habit before you hit assign.

Read the Mix on the Board

Every job on the DumpsterBossPro dispatch board carries the dumpster size in yards and a unit number. Scan each truck's day and read the sequence: 20, 20, 30, 10, 40. Every time the size changes from one delivery or swap to the next, ask whether the truck needs a yard stop there.

Sometimes a quick reorder fixes it. Move the 30 next to the 40 so one yard stop handles both. Move the 10 to the end so the driver grabs it on the last trip out. Small changes like that add up to hours over a week.

It also helps to agree on what the driver does when the size on the job does not match what is available. Call the office? Take the next size up? Leave it for tomorrow? Decide the rule in advance so the driver is not making a pricing decision on the spot.

Check Your Empties Before Promising Dates

The software does not track which unit is sitting where, so the size mix on the board is also a planning check you do yourself. If Thursday shows five 30-yard deliveries and you only have four empty 30s expected back by Wednesday night, something has to move. Better to know that on Monday than at 6 a.m. Thursday.

Look at upcoming pickups as well as deliveries. Pickups bring cans back into circulation. If you need more 20s for Friday, pulling the 20s that are due on Thursday on time matters more than usual.

Debris Type and Weight Go With Size

A 10-yard can full of concrete can be heavier than a 30 full of household junk. Debris type is recorded on every job, and it belongs in your size-mix thinking. Heavy materials often go in smaller cans for a reason, and a day of heavy pulls is hard on the truck and the driver even if the sizes look small.

It also affects billing. Scale-ticket weight in tons goes on the job after the dump, and tons over the included weight are billed per ton on the invoice. Size, debris type and weight together are what make a roll-off job profitable or not.

For customers who are not sure which size they need, a short question about the project helps you steer them. Too small, and you will be back for a swap in two days. Too large with heavy debris, and the weight becomes a problem. Getting the size right on the phone is the cheapest way to keep the mix sensible.

Plan the Mix, Then Let It Run

A good size mix is not about perfect sequences. It is about avoiding the obvious waste: three yard trips that could have been one, a 40 on the wrong truck, a delivery promised with no empty to send. Ten minutes of checking each morning prevents most of it.

Next up is dispatching swaps, the job type where size planning matters most. For the full set of dispatch tools, see the DumpsterBossPro roll-off dispatch software page.
