Services

Specialist engineering support from concept to operation

We provide focused consultancy across tunnelling, inspection, structural assessment, temporary works and civil engineering. Services can be commissioned as targeted reviews, defined design packages, independent checks or embedded project support.

Tunnel and Infrastructure Inspection

Inspection and investigation of tunnels and infrastructure assets to establish their condition, identify defects and support maintenance and repair decisions.

  • Condition surveys and assessments
  • Visual inspections and defect mapping
  • Inspection of structural fixings, connections and supports
  • Corrosion and material deterioration assessments
  • Planning and coordination of intrusive investigations and material testing
  • Inspection and monitoring strategies
  • Remedial and maintenance recommendations

Structural Assessment, Modelling and Remedial Design

Assessment of existing structures to understand their behaviour, establish structural capacity and develop practical repair or strengthening solutions.

  • Assessment of existing structures and asset integrity
  • Structural analysis and detailed calculations
  • Finite-element modelling
  • Structural capacity and loading assessments
  • Investigation of structural defects and failures
  • Repair and strengthening design
  • Technical support during remedial works

Tunnelling and Underground Engineering

Engineering support for the planning, design and construction of tunnels, shafts and underground structures across a range of ground conditions and construction methods.

  • Tunnel alignment, feasibility and concept development
  • Tunnel boring machine tunnelling
  • Sprayed-concrete-lined and conventionally excavated tunnels
  • Drill-and-blast tunnelling
  • Pipe jacking and microtunnelling
  • Shafts, tunnel connections and underground structures
  • Tunnel lining design, assessment and design review
  • Construction methodology and sequencing reviews

Temporary Works and Independent Checking

Temporary works engineering to support safe construction, practical installation sequences and coordination with permanent works.

  • Construction sequencing and programme support
  • Engineering management and design coordination
  • Site engineering and technical supervision
  • Resolution of site queries and construction-stage design issues
  • Coordination of specialist contractors and suppliers
  • Inspection and test planning, quality checks and handover support
  • CDM advisory support and design risk management

Civil, Structural and Geotechnical Design

Design of civil infrastructure and permanent works, considering structural requirements, ground conditions, construction methods and site constraints.

  • Concept and detailed civil and structural design
  • Reinforced concrete and steelwork design
  • Foundation design and assessment
  • Retaining structures and excavation support
  • Ground–structure interaction analysis
  • Drainage, chambers, duct routes and associated infrastructure
  • Design drawings, calculations and technical specifications
