Critical insight beneath the surface to reduce risk.
Beneath every project lies information that determines its success. Plowman Craven provides complete understanding of subsurface conditions to help clients plan, design and build with confidence.
By locating, modelling and assessing underground assets and structures, we reduce uncertainty, prevent costly clashes and support safe, efficient delivery.
Our subsurface data connects seamlessly with wider site and design information, creating a clear digital foundation for confident decision-making.
Understanding ground conditions is essential for safe, efficient construction. Our Ground Investigation Support service precisely records and correlates boreholes, trial pits and monitoring wells with utility and topographical data, reducing design errors, ground movement and delays.
Utility mapping is essential to risk management across the built environment. Our PAS 128-compliant surveys provide a clear understanding of buried utilities, preventing service strikes, protecting safety and supporting compliance. Integrated within digital models, PAS 128 data also enables long-term asset tracking and maintenance.
Complex sites demand a single, coordinated view of what lies beneath. Our Underground Geospatial Surveys combine utility detection, CCTV and sewer surveys into one digital model, improving coordination, reducing risk and supporting efficient construction.
Sewer networks play an essential role in public health and environmental protection. Our Sewer Surveys assess structural condition, capacity and connectivity to support compliance, maintenance planning and sustainable asset management. Early identification of issues prevents collapses, flooding and costly disruption.
Our CCTV Surveys use high-definition inspection to assess the condition and integrity of underground assets. Linking visual evidence to precise coordinates gives project teams confidence in drainage and service data before construction begins.
Trusted subsurface intelligence for safer, more predictable projects.
Plowman Craven combines decades of expertise with advanced digital workflows to deliver clarity where it matters most — below ground. Our Subsurface Mapping & Investigation services provide the insight and assurance needed to plan, design and build with confidence.
