Mass handling – how to control the mass flow in a project

Mass handling is the process of taking care of the material that arises in – and is needed for – a construction or civil engineering project: soil, clay, gravel, stone and rock. It is about knowing what material you have, what it contains, where it should go, and being able to show what actually happened.

The difference from the material itself matters: excavation material is what the material is, while mass handling is how you organise the flow of it. To understand the material and the rules around it – when it becomes waste, how it is classified and what applies in transport – read our complete guide to excavation material.

The biggest lever in mass handling sits before the first shovel even hits the ground. It is in planning that you decide whether material can be reused within the project, whether an embankment can be raised instead of trucking the surplus away, and whether a receiver is in place in time. The decisions made here drive both the cost and the climate footprint of the whole project.

What it costs to dispose of material is largely determined by how it is classified. The cleaner the material can be shown to be, the more – and cheaper – routes are available for it. Material that must be handled as contaminated or hazardous is significantly more expensive, both in receiving charges and in transport to a facility that will accept it. That makes classification one of the biggest cost items in the mass flow – and something you can influence with the right documentation.

Cleaner material is cheaper to dispose of

Material that can be recovered in a construction project is often cheaper to handle than material that has to be landfilled. For what is landfilled there is also a statutory landfill tax of several hundred kronor per tonne – a tax that is adjusted upward each year and charged on top of the receiving fee. That cost disappears if the material can be recovered instead. Each step up the classification ladder, from clean towards contaminated towards hazardous, normally means higher cost and fewer receivers willing to accept it.

Misclassification costs twice

Guessing wrong on classification is expensive in two ways. If material is not tested, it may have to be handled according to the most expensive assumption just to be safe. And if a receiving facility discovers during inspection that the material does not match what was declared, penalty fees are often added – and in the worst case the load has to be driven back and the whole handling redone. Many facilities charge extra for incorrectly declared material, on top of the higher treatment fee.

The right documentation keeps material in the right class

What keeps material in the right – and usually cheaper – class is well-considered documentation: correct sampling, proper classification and records the receiver can trust. If you can show the material is cleaner, you avoid paying for a higher class unnecessarily. The documentation is therefore not just a compliance issue – it is directly tied to what the project pays.

This is where traceability delivers concrete value. When every load is documented with classification, quantity and receiver, the documentation that keeps the material in the right class – and proves to the receiver that it is what you say it is – is in place. Pinpointer keeps that documentation collected per delivery.

In many projects, mass handling is fragmented: a consultant classifies, a contractor digs, a hauler drives, a facility receives – and no one has the full picture. Information lives in Excel sheets, on paper and in phone calls. When something deviates, it is often discovered only at final reconciliation, when the money has already been spent.

The steps below are one example of how a mass flow can run. The order and content vary between projects – but most projects move through some variant of this chain.

Checks on the receiver's and hauler's permits, deadlines and the full rulebook are covered in our guide to excavation material.

Mass handling works best when every party works in the same flow instead of in their own separate system.

When the mass flow is gathered in one system instead of in scattered Excel sheets, every party gets the same picture in real time. Each load is documented automatically: weighed amount, material type, classification, receiver, position and timestamp. Deviations show up immediately, and the basis for follow-up and reporting is built up while work is ongoing.

That is what Pinpointer does – we gather the entire mass flow, from excavation to receiving, with per-load traceability and support for all five roles.

If the material comes from an area that is known or suspected to be contaminated, the requirements rise along the entire chain. Remediation works have to be notified to the supervisory authority before they start, and when the work is finished a final report must show what was done – including where the contaminated material was transported and how it was handled.

This is where the follow-up step of the mass flow goes from nice to have to necessary. The final report requires someone to be able to account for where every load went – and that account is hard to reconstruct after the fact if it was not built up while the work was ongoing. The rules around this – the Section 28 notification, allocation of responsibility and what the final report must contain – are covered in our guide to excavation material.
