Mitigation in the construction industry
The term ‘mitigate’ means to make less severe or serious.
This can be important in the construction industry in a number of different circumstances.
- In relation to project delays, it refers to minimising the impact of the risk event (an event or cause of delay or disruption). For example, acceleration might be used to mitigate a delay. Where there is a claim for an extension of time, the contractor may be required to mitigate the delay and any resulting loss, even where the fault is not their own.
- In terms of losses incurred, it can refer to claimant's duty to mitigate their loss. A claimant will generally not be allowed to recover damage which could have been avoided had the claimant acted reasonably. For more information see: Mitigation of loss.
- In relation to planning policy, planning obligations or planning conditions might be used to mitigate or compensate for the negative impacts of a development. For more information see: Planning obligation and planning condition.
- In terms of risks, a contingency plan might be enacted to mitigate project risks, such as adverse weather, industrial disputes and so on. For more information see: Contingency plan.
Mitigation strategies might also be used in relation to:
- Environmental impact.
- Loss of habitat.
- Carbon emissions.
- Flood protection.
- Duty to warn.
A handbook on environmental impact assessment, 4th edition, published by Scottish Natural Heritage in 2013, suggests that:
These are the measures taken to avoid, cancel or reduce adverse impacts of a project. They are:
- Avoidance measures: Designed to avoid or eliminate any adverse impacts arising in the first place, including alternative or ‘do nothing’ options;
- Cancellation measures: Designed to nullify or cancel out any adverse effects of a project before adverse effects are felt;
- Reduction measures: Designed to minimise or at least reduce adverse impacts remaining after avoidance and cancellation measures have been applied to a project.
Culvert, screen and outfall manual, (CIRIA C786) published by CIRIA in 2019, suggests that the mitigation hierarchy is typically:
NB Global Warming of 1.5 ºC, Glossary, published by the Intergovernmental Panel on Climate Change (IPCC) in 2018, defines mitigation (of climate change) as: ‘A human intervention to reduce emissions or enhance the sinks of greenhouse gases.’
