Highways and Infrastructure

Site Access and Spine Road Design:

We design strategic access routes and internal highways to unlock development potential and ensure safe, efficient connectivity.

  • Site access junction design (priority, roundabout, and signal-controlled)
  • Spine road design for phased residential and mixed-use developments
  • Vehicle tracking and swept path analysis
  • Road safety audits coordination
  • Visibility splay and speed survey assessments

S278 and S38 Technical Approval:

We prepare and manage technical submissions for adoptable highway works under Sections 278 and 38 of the Highways Act 1980.

  • Section 278 highway works for new junctions, signals, and access improvements
  • Section 38 submissions for adoptable internal roads and drainage
  • Coordination with local highway authorities and adoption teams
  • Preparation of construction details and specification documents
  • Support through design checks, legal agreements, and inspections

External Levels and Compliance Design:

We deliver level strategies that support planning and detailed design for large-scale residential and commercial schemes, ensuring accessibility and compliance with relevant regulations.

  • Finished floor level (FFL) strategies and coordination with drainage
  • Access grading in line with Building Regulations Part M and DDA requirements
  • Design for inclusive access to plots, footways, and public open space
  • Retaining structure integration and cut/fill balance support
  • Collaboration with architects, planners, and landscape teams

Floodplain Compensation and Fluvial Protection:

We help developments progress in areas of fluvial risk by designing mitigation strategies that ensure safety, compliance, and resilience to flooding.

  • Floodplain compensation design to offset loss of flood storage volume
  • Coordination with Flood Risk Assessments and hydraulic modelling
  • Assessment of existing and proposed ground levels within flood zones
  • Design of raised development platforms with sufficient freeboard
  • Compliance with Environment Agency guidance and local flood policy
