The requirement for and Environmental (or Ecological) Clerk of Works (ECoW) often appears as a planning condition for development projects. This requirement is to monitor that mitigation measures and environmental management practices outlined in the planning documents / other planning conditions are delivered.
ECoWs require a wide base of knowledge to support the role, including:

  • Ecology and protected species
  • Water management and pollution control
  • Waste and resource management
  • Auditing skills and project management

An ECoW may be required during the pre-construction, construction and post-construction phases. The role of the ECoW varies project to project, but as a minimum the ECoW is there to monitor and advise on compliance with planning conditions, environmental legislation and project specific documents .
ECoWs act independently, sitting between the project teams and the regulators, facilitating the best possible outcome for the Client, whilst keeping the project compliant.

Our ECoW Expertise

Atmos has extensive experience of providing ECoW services across a range of sectors and projects within varying scopes including: renewable energy, gas pipeline, overhead power line, residential housing and physical infrastructure (road, rail and grid) developments.  

Our approach is to ensure that sensitive environmental site issues are identified early and managed according to good practice guidelines, whilst recognising the need to progress within the required time-scales. We recognise that effective communication is paramount to project success and have a proven track record of effectively liaising with statutory bodies, site contractors and project managers to achieve successful and commercially pragmatic outcomes.

Working in partnership with developers and their contractors, we act in an independent capacity, undertaking compliance monitoring and providing good practice advice and guidance. Our ECoW team all hold up to date CSCS cards and relevant Health and Safety qualifications.  As such they are able to provide both supervisory and advisory ECoW roles.
