A large proportion of the works take place within historical town cores, as well as in rural areas within rich archaeological landscapes where there is the potential for the presence of previously unknown archaeological remains (both above and below ground). In urban areas in particular there is also the potential for upstanding recorded heritage located in close proximity to works that may require the implementation of appropriate measures to protect them during on-site works.
Key considerations are identifying the potential/level of risk for previously unrecorded sub-surface archaeological remains and the location of recorded upstanding remains in order to implement appropriate mitigation measures.
To date AMS has assessed upwards of 100 water mains schemes, identifying potential impacts on the archaeological and architectural heritage resource and implementing appropriate mitigation measures including archaeological monitoring and preservation by record. Works have included:
- Assessment of the baseline heritage (archaeological and architectural) environment.
- Assessment of the level of risk for the presence of previously unknown archaeological remains, both above and below ground.
- Design and implementation of appropriate mitigation measures to offset any identified impacts.
- Licenced monitoring of areas identified as archaeologically sensitive; preservation by record of any identified archaeological remains or preservation in situ where feasible.
- Advise on appropriate mitigation to protect upstanding heritage located in close proximity to proposed works e.g. from machine movements, noise vibration etc.
