Project Scope and Challenges

WJ’s scope covered extensive baseline and construction-phase environmental monitoring, including:

  • Water Sampling & Field Testing: Conducting multi-parameter field assessments and laboratory 
chemical testing to monitor water quality.
  • Flow & Ecology Surveys: Assessing hydrological changes and ecological impact across various watercourses.
  • Instrumentation & Telemetric Monitoring: Providing 
real-time data collection to track groundwater and surface water conditions.
  • Data Visualisation & Reporting: Delivering structured reports in compliance with HS2’s technical specifications and the Water Framework Directive.

Managing over 428 active borehole and surface water monitoring locations, along with 215 active discharge points, required a highly organised approach. Testing schedules varied based on site conditions, weather events, and construction activities, demanding a flexible and proactive strategy.

WJ’s Innovative Approach

WJ deployed cutting-edge technology to streamline data management and forecasting:

  • Custom-Developed Monitoring Software: Allowed field teams to access real-time location, activity status, 
and sampling requirements on tablets, ensuring 
efficient operations.
  • Automated Lookahead Programme: Provided dynamic forecasting of future monitoring needs based on evolving construction schedules, reducing delays 
and improving cost planning.
  • Regulatory Compliance & Environmental Protection: Ensured strict adherence to HS2’s environmental commitments by proactively managing water quality data and providing early warnings on potential risks.
A Key Contribution to HS2’s Success

WJ’s real-time data collection and reporting systems enabled HS2’s construction teams to make informed decisions, optimising project efficiency while maintaining environmental integrity. The ability to dynamically adjust monitoring schedules improved compliance tracking and minimised disruptions.
