How vacuum excavation can significantly reduce reinstatement costs
Vacuum excavation can reduce reinstatement costs by limiting the size of the excavation, reducing spoil volumes, minimising disturbance to surrounding surfaces and lowering the risk of expensive damage to buried utilities.
That can be particularly valuable on highways, utility projects, urban sites and other locations where reinstatement can become a significant part of the total project cost.
Vac-Ex, operated by John Mee Construction Ltd, provides nationwide vacuum and suction excavation using specialist equipment and experienced operators.
What are reinstatement costs in excavation?
Reinstatement costs are the costs involved in restoring an excavation area after the work has been completed.
Depending on the project, they can include:
- Backfilling the excavation
- Replacing sub-base and surfacing
- Road or footway reinstatement
- Replacing topsoil or landscaping
- Removing or disposing of spoil
- Importing replacement material
- Additional labour and plant
- Traffic management
- Repairs following accidental service damage
The larger and more disruptive the excavation, the more work may be required to return the area to its original condition.
How does vacuum excavation reduce reinstatement costs?
Vacuum excavation can reduce reinstatement costs because it allows contractors to excavate more precisely and remove only the material needed to expose or access the target area.
The main savings can come from:
- Smaller excavation footprints
- Less surface disruption
- Reduced spoil volumes
- Lower risk of damaging buried services
- Cleaner material handling
- Less unnecessary manual excavation
- Shorter reinstatement programmes in suitable applications
That is one reason vacuum excavation can be more valuable when assessed against the total project cost rather than simply the day rate of the equipment.
Smaller excavations can mean less to reinstate
One of the clearest cost advantages of vacuum excavation is the ability to create a more targeted excavation.
Traditional mechanical excavation can sometimes require a larger working area to provide access for the bucket and reduce the risk of contact with underground services.
Vacuum excavation removes material through a suction hose, allowing the operator to expose buried infrastructure progressively and with greater control.
If a smaller area is disturbed, there may be less road surface, pavement, verge, landscaping or other material to replace afterwards.
This is particularly useful on highway excavation projects, where every additional area of carriageway or footway opened can increase reinstatement and traffic-management requirements.
