How we help
Integrated water and highways engineering for infrastructure.
Infrastructure projects demand coordinated flood risk, drainage, and highways inputs across complex alignments. We deliver catchment-scale modelling, DMRB-compliant highways design, and SuDS strategies that satisfy multiple authorities.
- Catchment-scale flood modelling for linear and area-wide schemes
- DMRB highways design with S278/S38 adoption support
- SuDS design for transport corridors and public realm
Our Approach
From constraint mapping to construction support.
-
Constraint mapping
We map flood, drainage, and highways constraints across the project corridor.
-
Coordinated design
We align water, civils, and environmental inputs into one design package.
-
Regulatory engagement
We liaise with the EA, LLFA, and highways authorities to secure approvals.
-
Construction support
We provide technical supervision and resolve site issues during build.
