When we carry out environmental screening we consult with English Heritage or the relevant county archaeological officer if a capital scheme could affect buried archaeology or other cultural heritage.
If our work is going to have an impact and we are unable to avoid any remains, we carry out a range of archaeological assessments and mitigation to reduce any adverse impacts on the historic environment.
- desk based assessments - all the known documentary evidence relating to the area is evaluated to gauge the potential impact
- non-intrusive evaluations such as geophysical surveys, field walking or landscape assessments
- intrusive evaluations including trial trenching or excavations of sections by specialists
- mitigation during construction such as an archaeological watching brief which involves a specialist archaeological contractor being on site to monitor and record any features encountered during construction
- post excavation reporting so that the public and specialists are aware of our discoveries when we encounter significant archaeological remains.
The above techniques are carried out by specialist archaeological contractors working closely with our project teams, county archaeological officers and, where relevant, English Heritage.
The results of this work and our excavations becomes part of the relevant local authority’s historic environment record which is publicly available.
